vh 7b5fd91d3c docs(gemma4-erp-tune): root-cause the 8.6% MFU — attention on Ampere kernels, 29.9% padding 
Run-01 was killed at step 19 by operator instruction to root-cause before
spending a ~13.9h window. Two independent methods now agree on where the step
time went, and neither was the hypothesis the consult panel converged on.

Scaling fit (3 points, 2 params, residuals <3ms over an 8x range):
  A = 6.87e-4 s/token, B = 8.85e-8 s/token^2
  quadratic share 20.9% @ w=2048 -> 67.8% @ w=16384
  No fixed term was needed, which refutes launch-bound outright.

Profiler kernel table (device rows only):
  attention   22,835.8 ms  65.2%   fmha_cutlass*_sm80
  dense GEMM   2,774.0 ms   7.9%
  other        5,739.0 ms  16.4%

The attention kernels are sm80 — Ampere-generation CUTLASS running on an
sm_120 Blackwell card, with the forward on the gmem fallback tier. That is the
mechanism behind 100% SM utilisation at 27 of 304 available TFLOPS.

Correctness cleared separately: the sliding mask asserts at max 1024
allowed/row, so the 25 windowed layers were genuinely windowed. The same probe
found that right-padding is what pins the 5 global layers to an explicit 4D
mask and off the is_causal fast path — measured at 9.4% slower for 24% less
loss work at fixed width.

The largest available win is not the attention kernel. The corpus is 29.9%
padding, and bucket-to-pair + shuffle-to-mix takes it to 0.0% for >=35.5% wall
clock, no new dependency, unchanged peak memory. Bucket size turned out not to
be a diversity knob — roots per accumulation window are flat across a 256x
range, so the global micro-batch shuffle does that work alone and the bucket
should be tight.

Adds docs/pfi/training-throughput-playbook.md as the durable model-agnostic
home (sibling to the quantization playbook), the four probes under
scripts/training-probes/ with raw output kept for re-derivation, and a §6 to
the sizing doc carrying the Gemma-4-specific numbers and round-2 restart
parameters.

Measured negatives recorded so they are not re-chased: grouped_mm (0.9%
slower, and MoE is only 7.9% of the step), CUDA graphs / torch.compile over
the expert loop (no fixed cost to amortise), liger fused CE (~1-3% lever),
FA4 on sm_120.

Round-1 state preserved: 609MB encode cache, order manifest, truncation
report, resume script. No checkpoints — it died at step 19 and the first was
due at 100, so the lora_B inert-adapter gate never ran and moves to the
restart.

vh 872c2c562f memory: the MFU hunt — two hypotheses measured and killed, consult dispatched 
Records what has actually been ruled out rather than what is suspected.

The hardware is fine: a plain dense GEMM at the same shape reaches
97.1% of the benchmarked 313.8 TFLOPS peak.

The Python expert loop is not the cause, which was my hypothesis and I
was confident in it. transformers' grouped_mm experts backend runs
0.9% SLOWER than eager with bit-identical output and identical peak
memory, and torch 2.13 has the kernel available, so it is not falling
back for lack of one.

MoE is not the bottleneck at all. Isolated at real shapes the block
runs at 26.5% of peak with 36% of its time in pure gather/scatter, and
a dispatch-free bmm version would reach 80.9% — but the whole MoE
contribution is only about 10% of a step. Making it free buys 7%.

So roughly 90% of the time is unaccounted for. The leading untested
hypothesis is that the five full_attention layers use global_head_dim
512, above FlashAttention-2's 256 cap, which would push SDPA onto a
slow backend for O(n^2) attention at sequence 16384.

Also records that the earlier 5% MFU figure was wrong in two ways —
unpadded tokens and a guessed peak — and that the operator caught it.
Padding is real but secondary at 29.9%.

Consult dispatched to brokkr-smithy-dev for the frontier-dwarf panel.

vh 07743c6aff memory: snapshot — tune training unattended, MFU root-caused to a Python expert loop 
The in-flight section is rewritten around the run itself rather than
the decisions that led to it. The sizing and seat-call bullet collapses
to a pointer now that both are executed; its detail lives in
docs/pfi/gemma4-erp-tune-sizing.md.

Adds the measured MFU finding: 27.1 TFLOPS against a benchmarked 313.8
TFLOPS peak, root-caused by reading the source rather than inferring —
transformers runs the Gemma-4 experts in a Python loop, 128 experts
across 30 layers, roughly 11,500 iterations per optimizer step under
gradient checkpointing. Padding is a secondary 29.9% tax.

Records that my first estimate of 5% MFU was wrong in two compounding
ways: divided by unpadded tokens, and compared against a guessed peak
rather than a measured one. The operator pushed back on the number and
was right to.

The fused MoE kernel is deferred work with a tracking surface — park
id 47 — per the snapshot rule that deferred decisions go in Recent
decisions with a pointer, never into the volatile in-flight section.

Also records the resume trap: the original launch command begins with
rm -rf on the output directory, which would destroy both the encode
cache and every checkpoint. resume-run-01.sh exists so that cannot
happen.

vh d6dfd61c91 memory: the ERP tune is running — override granted, 12 defects fixed first 
Operator overrode the corpus gate for one run on 2026-08-25, with the
grant staged beside the recipe rather than asserted in chat. It
deliberately does not flip any root's training_eligible flag, so the
signal that made the run stop in the first place survives intact.

Records where the run lives, what it is configured with, how to restore
the fleet, and the two lessons that generalise past this project.

The first is inert gates. Two turned up in one evening — auditcore,
whose CSAM hard-drop never fired across 42,662 records, and
validate_vision_keys, which compared model.state_dict() against itself
and could not fail on any input. Both read as guards. The question that
catches them is not whether the check passes but whether it can fail.

The second is an invariant enforced on one code path and not its
sibling. That was my own bug: INV-T9 requires a window to hold at least
one complete assistant turn, and I enforced it where the window is cut
but not where it fits, so a trailing user-only remainder became a
zero-loss window and killed the first launch. Same shape as the inert
gates, in code I wrote an hour earlier.

Two further foot-guns worth the space: enable_input_require_grads is
mandatory beside gradient checkpointing on a frozen base, or every
adapter stays at its initialisation and the run completes successfully
having learned nothing; and the upstream Gemma-4 template forward-scans
to suppress a closing turn marker before another assistant message, so
incremental rendering cannot tile against it and assistant runs must be
merged first.

vh 33433e0d1e docs(gemma4-erp-tune): replace the estimates with measurements — they were 3x optimistic 
Ran the loss path on the real checkpoint on GPU0 with synthetic tokens.
The arithmetic held for parameter counts and was badly wrong for
activation memory.

    naive CE   bsz1 seq 8192    81.93 GiB
    naive CE   bsz1 seq16384    OOM
    chunked CE bsz1 seq16384    65.66 GiB
    chunked CE bsz2 seq16384    79.71 GiB   <- the run config
    chunked CE bsz4 seq16384    OOM

The marginal cost of an extra 16,384-token sequence is ~14 GiB, not the
~5 GiB estimated: the estimate modelled gradient checkpointing as
storing layer inputs plus a modest recompute peak, and the real MoE
recompute peak with top-8-of-128 routing and its scatter/gather buffers
is far heavier. Dense-model intuition does not size an MoE run.

Two predictions landed exactly — 205 target modules and 74,342,400
trainable params at r64 — which is why the rest of the model of the
thing is still worth trusting.

The headline is that chunked CE at seq 16384 costs 16 GiB less than
naive CE at seq 8192, so chunking is what makes brokkr's 16384
recommendation reachable rather than an optimisation on top of it.
max_seq_len moves 8192 -> 16384 on his truncation finding: the cap
drops 6.2% of samples but 22.4% of tokens, concentrated entirely in
dialogue, which is 60% of the mix.

Also records the four harness changes this required (eitri-smithy
62b556b), including the inert-adapter trap: without
enable_input_require_grads() alongside gradient checkpointing on a
frozen base, no gradient reaches the adapters, every one stays at its
initialisation, and the run completes successfully having learned
nothing.

vh 47ec3d1a97 memory: the ERP tune is blocked on a corpus gate only the operator can clear 
Every clean-v1 CLEANROOT carries training_eligible: false with two named
blockers, and the recipe states plainly that nothing in it is Charter §3
training-eligible.

I initially read scoped_grant: operator-2026-08-22 as authorization and
told brokkr-smithy-dev I was proceeding. That was wrong, and the person
who wrote the field corrected it: the grant governs INV-4 one-way tier
inheritance — the adapter is permanently internal-erp-rnd and never
distributable — not training clearance.

The stage-2 detector is measured-inert rather than merely unvalidated.
auditcore v3.7.2 returned its hard-drop exit code zero times across
42,662 raw RP records, its printed verdict ignores its own printed
threshold, and it passed a record a blind audit had already identified
as sexual content involving a participant the text marks as a child.

Verified the one thing that decides whether that specific record reaches
training: pippa-5083 is present in kept-manifest.jsonl (4,551 rows) and
absent from recipe-dedup-kept.jsonl (20,473 rows), which is the survivor
list the harness gates on. The substitute lexical screen caught it. That
is one known instance caught by a stopgap and says nothing about what the
screen misses.

Both brokkr and I recommend stopping. Neither blocker is hours of work.

vh c9943b1507 docs(gemma4-erp-tune): whole-card placement — gen moves to GPU1, sec stands down 
Operator chose a third placement over the two the sizing offered: rather
than train beside gen on GPU0 or on GPU1 in mog-sec's slot, move gen to
GPU1 and empty GPU0 completely. The tune gets 95.60 GiB with no
co-tenant and gen never goes dark beyond its own restart.

Revised run parameters, since a whole card changes them:

- micro-batch 8 (71.8 GiB of 95.60) rather than 4, grad-accum 1, giving
  888 optimizer steps instead of 444. At one epoch the step count is
  worth having, and 8 x 8192 tokens puts ~4,096 rows through each expert
  per step against ~512 at micro-batch 1 — a far healthier GEMM on
  704-wide experts.
- Gradient checkpointing stays ON. Dropping it takes ~17% off wall-clock
  but pushes activations to ~24 GiB per sequence, which forces
  micro-batch 1 and costs 8x on MoE efficiency. Wide beats shallow.
- Scriberr stays on GPU1. The previous revision suggested moving it to
  GPU0, which was correct only while training was going to live on GPU1.

Records the ordering constraint in both directions, the elway identity
requirement, and that sec's aliases should be allowed to fail at the
gateway rather than be substituted with another model.

vh 9d70100867 feat(ana-ml2): elway playbooks to open and close the ERP/RP tune window 
Operator call: rather than train beside gen on GPU0, move gen to GPU1 and
stand sec down for the night, so the tune gets a whole 95.60 GiB card and
the fleet's general seat never goes dark beyond its own restart.

Order is load-bearing in both directions and the playbooks enforce it.
gen runs at --gpu-memory-utilization 0.43, which vLLM reads as a fraction
of TOTAL card memory: 42,091 MiB must be FREE at startup or the engine
refuses to boot. GPU1 has 19,446 MiB free while mog-sec is up, so
recreating gen onto GPU1 first would take the main seat down and leave it
down. mog-sec stops first and a hard gate checks the freed memory before
gen is touched. The close playbook mirrors it: gen must vacate GPU1
before mog-sec starts, since mog-sec needs 50,901 MiB of its own.

Close opens with a gate that refuses to run while a process is still
resident on GPU0, so it cannot evict a training run mid-flight.
Override with --var allow_busy_gpu0=true.

Three defects found and fixed while landing this, all worth keeping:

- Verifying GPU residency via `docker inspect --format {{.State.Pid}}`
  never matches. vLLM V1 runs EngineCore as a child of the container's
  pid 1, and it is the child that holds the memory and that nvidia-smi
  reports. Match by cgroup instead.
- A step's `sudo: true` does not extend to its when/creates/changed_when
  guards, which run as the login user. The root-only .env made an
  unsudo'd grep exit 2, so the GPU-id flip SILENTLY SKIPPED. The
  effective-value assert is what caught it.
- That assert originally grepped the config YAML for -\s*'?1'? and failed
  against compose's double-quoted `- "1"`. Parse the JSON with jq; an
  assert that fails for the wrong reason is worse than no assert.

elway must be invoked as infra-ops@10.250.50.54 rather than the ana-ml2
ssh-target, which resolves to lkraven and has no NOPASSWD sudo.

vh c507db9ac0 docs(gemma4-erp-tune): size the run against the checkpoint — QLoRA is structurally unavailable 
The proposed shape was QLoRA r64. It cannot be run as specified. The
checkpoint stores each layer's 128 experts as two fused 3-D nn.Parameter
tensors (experts.gate_up_proj [128,1408,2816], experts.down_proj
[128,2816,704] — no .weight suffix, so they are parameters, not modules).
bitsandbytes 4-bit replacement walks nn.Linear only, so 22.84B params /
42.54 GiB — 88.5% of the model — is skipped and stays BF16. load_in_4bit
saves ~3.1 GiB of 48.07 and does not error while doing it.

Verdict: plain LoRA on BF16, ~57.6 GiB at micro-batch 1, +2.5 GiB per
additional 8192-token sequence.

Two sizing items were absent from the brief and both are load-bearing:

- vocab 262,144 x seq 8,192 = 2.147B logits, with final_logit_softcapping
  30.0 adding a saved pre-cap tensor. Naive HF cross-entropy peaks at
  ~28-30 GiB transient at batch 1, which puts the run at ~85.6 GiB on a
  95.6 GiB card — it starts, then OOMs on the first long sample. Fused or
  chunked linear CE is mandatory and must be smoke-proven before a window
  is booked, since Liger may not carry a Gemma-4 MoE patch.
- v_proj does not exist on layers 5/11/17/23/29 (attention_k_eq_v on the
  full-attention layers). A v_proj target silently produces no adapter
  there, and k_proj adapts K and V simultaneously. 45.96M trainable at
  r64 across q/k/v/o.

Placement, measured: GPU0 has 53.46 GiB free beside gen, ~4 GiB short, and
gen's footprint grows with uptime. Stopping mog-sec frees 74.29 GiB on
GPU1, which holds micro-batch 4 at 61.8 GiB with margin for Scriberr.
Recommend standing down sec (2 aliases, last request ~5h ago) rather than
gen (7 aliases, 765 busy-engine log lines in 24h).

Estimated 1.28e18 FLOPs for the epoch at ~3.67B active params; 4-10 hours
at 10-25% MFU. 7,104 packed sequences is only 444 optimizer steps at
effective batch 16, which makes the wall-clock-checkpointing amendment
concrete rather than hypothetical.

Package as a uv venv on /tank: root is 91% full (36 GB) with
/var/lib/docker on it.

vh 9d0e628643 memory: correct the vLLM version claim — ana-ml2 runs a spread, and 0.27.1 is on disk 
The snapshot recorded "ana-ml2 now runs vLLM 0.26.0". That is true of the
char-rp seat's pin and false of the box, which the operator caught immediately.

Measured per running container: gen is on nightly-311b3513 reporting
0.27.2rc1.dev150, mog-sec on nightly-e9d1398d reporting 0.26.1rc1.dev1102, and
rerank-a3 / coder / reward / embed still on 0.24.0. char-rp and the trainee
bench stack are pinned to v0.26.0. So there is no single "the version" for this
host, and stating one invites exactly the wrong retest.

The correction improves the LoRA question rather than complicating it:
vllm/vllm-openai:v0.27.1 is already on disk and unused — a TAGGED release, not
a nightly, roughly four months past the 0.24.0 where the silent-no-op was
diagnosed. That is the right target for a decision test: no nightly variance,
no pull. The retest instruction in both the decision entry and the handoff now
names it.

vh 668e590e7d memory: snapshot — char-rp on the Gemma-4 MoE, abliterated trainee staged, QLoRA sizing next 
Captures an evening that ran from an OOM crash-loop to a measured trainee base.

The durable lessons, none of which CLAUDE.md can carry: --gpu-memory-utilization
sizes the KV cache and does not cover CUDA context or graphs, which is half of
why a seat that fit on the 21st stopped fitting on the 24th; the other half is
that gen's footprint GROWS WITH UPTIME (38.5 GiB fresh against 45.6 GiB after
three days, same container, same flag), so headroom arithmetic against a
long-running gen measures a moving number. The stale-chat-template trap turned
out to be endemic across third-party Gemma-4 derivatives rather than a one-off,
and it is silent in both directions — wrong prompt when serving, train/serve
skew when tuning. And a benchmark finding was retracted because 12% on a
five-option task is below the 20% chance floor: a below-chance score indicts the
instrument before the model, and a preflight can be thorough while aimed in the
wrong direction.

Records the serving decision for the tuned model with its history intact:
LoRA-on-NVFP4 is preferred if it works, merged weights the expected fallback,
but the archived root-cause says the objection was never NVFP4-specific — vLLM
0.24.0's LoRA application was a silent no-op proven quant-agnostic, and ana-ml2
now runs 0.26.0. Retest before designing around merge; the answer changes what
Eitri's harness must emit, and he is still early.

Auto-archival moved 5 entries (Recent decisions) to archival-memory.md; the
guards held back the rest of the 78 age-eligible candidates because their bodies
carry open deferred-work language, per the keep-when-unsure rule. Index sits at
286 lines, above the ~250 target and reported rather than forced.

vh 5415fd4b30 docs(gemma4-charrp): abliteration measured in isolation — close to free, but it MOVES capability 
Second bench window, operator-authorised after an initial decline and reversal.
Stock BF16 against the llmfan46 abliterated BF16: same precision, same pinned
upstream template, same 192 items, CoT off. Abliteration was the only axis that
moved, which is what the previous run could not claim.

Net core cost is 0.6 points — but the headline understates what happened.
Capability MOVED rather than degraded: five items lost on contradiction
detection, four gained on spatial composition, nearly cancelling. A gain was not
predicted by anyone, least of all on that axis.

The decision this was authorised to settle: llmfan46 stands as the trainee base.
No case for re-staging on TrevorJS at KL 0.09 over 0.6 points — the KL gap
between the builds is smaller than the gap this measurement failed to find.

Both limits recorded rather than buried, per brokkr-smithy-dev: the swings are
~5 and ~4 items at n=32, so the -15.6/+12.5 percentages read more precisely than
the measurement supports and only marginals were run; and this says nothing
about quantization, because the stock-NVFP4 T2 figure came from n=16 against
n=32 here — different item counts mean different item sets, so that comparison
is n-confounded and is not being made.

Turnaround was five minutes rather than fifteen because the gemma4-trainee-bench
stack already existed — itself the residue of debugging a 35-restart crash-loop
caused by the production compose hardcoding --quantization compressed-tensors.
The fix outlasted the incident.

gen restored and verified through the gateway; char-rp remains down deliberately;
bench stack env reset to the heretic base for the post-tune gate.
 2026-08-24 15:39:43 -07:00
vh 019ccff7e8 feat(gemma4-trainee-bench): BF16 bench stack; record that gen's footprint grows with uptime 
Adds an ephemeral stack for serving the BF16 trainee base on :8016 under the
char-rp aliases, so the abliterated base can be measured on the same battery and
the same gateway routes as the served seat with no harness edit.

It is a separate stack rather than another variable on gemma4-charrp because
that compose hardcodes `--quantization compressed-tensors` for the NVFP4 build.
Pointing it at unquantized BF16 weights crash-loops immediately —
`TypeError: CompressedTensorsConfig.__init__() missing 3 required positional
arguments: 'target_scheme_map', 'ignore', 'quant_format'` — vLLM trying to read
a quantization config out of a checkpoint that has none. 35 restarts before it
was caught. `restart: "no"` here so a bench seat cannot resurrect itself and
block gen's restore, and no homepage labels so it leaves no permanently-offline
dashboard card.

It cannot coexist with gen and says so: 48.07 GiB of BF16 weights plus gen's
footprint exceeds the 94.97 GiB card before any KV cache. Running it means gen
is stopped.

THE MORE USEFUL FINDING is in the meromero env note: gen's memory footprint
GROWS WITH UPTIME. Measured today at 46,726 MiB (45.6 GiB) after ~3 days up, and
39,424 MiB (38.5 GiB) immediately after a restart — same container, same
--gpu-memory-utilization 0.43, ~7 GiB apart. That is the missing half of this
afternoon's crash-loop: the char-rp seat "fit on the 21st and stopped fitting on
the 24th" because nothing about char-rp changed and gen crept up underneath it.
Headroom arithmetic done against a long-running gen is measuring a moving
number, so the note now says to measure against a freshly-restarted one.

Operator's requested end state reached and verified through the gateway: gen and
summarizer both 200, char-rp down deliberately to hold GPU0 headroom for the
upcoming trainee run, bench seat stopped.

vh 14ff4a3f57 docs(gemma4-charrp): stage two abliterated trainee bases; record the endemic stale-template trap 
The operator directed that the ERP/RP trainee base be a low-damage abliterated
instruct build rather than the stock checkpoint. Two are now staged under
/tank/aimodels/, both BF16, both unquantized, both matching upstream's 51.61 GB
/ 25.8B shape with only transformers_version differing in config:

  gemma4-26b-a4b-it-heretic-bf16       llmfan46, Heretic v1.2.0 ARA, KL 0.1237, refusals 3/100
  gemma4-26b-a4b-it-abliterated-bf16   TrevorJS, KL 0.09, 1/100 effective and 5/686 cross-dataset

"Low damage" was treated as a measurable claim rather than a description: the
field spreads from KL 0.09 to 0.4118 and the table is in the README so the next
choice is made on numbers. Fleet anchor for reading them — our own abliteration
work found Heretic at KL 0.12 preserved the MTP head at 83.7% acceptance, so
both staged builds sit inside an already-validated band rather than past it.
huihui-ai is rejected despite its reputation: no published metrics, its own card
calls the method a crude proof-of-concept, it abliterates both thinking and
non-thinking modes, and its parameter count runs ~738M over upstream. The
operator's independent read matched.

The more durable finding is the chat template. NOT ONE third-party Gemma-4
derivative pulled here ships upstream's — three independent repos carry the
identical stale 266-line file (sha 58c66fdee4afa297), llmfan46 carries a third
365-line variant, and only the RedHatAI NVFP4 build matches upstream's
6a1015c47ccfcfa6. It propagated through the ecosystem rather than one packager
slipping, and it is now recorded as a class rather than as the single incident
that surfaced it during the A16 control staging.

That matters twice over and silently both times: serving a mismatched template
renders a different prompt, which is why production pins it; and training
through `base/chat_template.jinja` means training on a different prompt format
than production serves — train/serve skew with no error, presenting as a tuning
failure. brokkr-smithy-dev has been warned on the training side while the
harness contract is still early enough to amend.

vh 8d6a9390de docs(gemma4-charrp): RETRACT the contradiction-deficit claim — the item was ill-posed 
Supersedes what commit 3446367 recorded. That message stated the A16 control
"settles a question" and quoted 12% contradiction detection against gen's 81%.
The quantization half of it stands; the deficit it was measuring does not exist.

brokkr-smithy-dev retracted the finding after the operator asked to see the
individual items. The task presented two mutually contradicting statements and
asked for "the contradicting statement" — but CONTRADICTION IS SYMMETRIC.
Neither statement was more the contradicting one, the model had no way to know
which had been inserted, and it consistently named the absolute claim: a
defensible reading that the labelling scored wrong on every single item.

The tell was there and both of us walked past it: 12% on a five-option task is
BELOW THE 20% CHANCE FLOOR. A below-chance score indicts the instrument before
it indicts the model. That should be the first reaction to a below-chance
result, not a late one, and it is now written into the README as such.

Retracted: "the model owns the contradiction deficit"; "domain tuning costs 43
points of contradiction detection" (which on a sound instrument does not shrink
but REVERSES); and every pre-fix T2 number for Gemma-4, MeroMero-v2, sec and
gen. A second defect surfaced during the fix — all generators shared one RNG, so
rewriting one task reshuffled every task after it.

What survives is real and worth separating out: the A16 control result holds.
Activation precision is close to free on this workload, every other task
identical across the W4A4 and W4A16 builds. The two staging confounds caught
before the run — the two Hub repos named NVFP4A16 that declare 4-bit
activations, and the stale chat template — were independent of the item defect
and remain load-bearing. On the corrected instrument Gemma leads the very axis
it was suspected of failing (94% against sec's 81% and gen's 50%); its actual
weak axis with thinking off is spatial composition at 69%.

Recorded as a dated superseded-claims table rather than a silent edit, per the
repo's quant-work convention, so notes elsewhere stop misleading people.

vh 3446367d5e feat(gemma4-charrp): pin the chat template; A16 control run executed and reverted 
The template is now passed explicitly, defaulting to the A4 build's
chat_template.jinja. That is a no-op for what is served — the A4 build ships
that exact file, byte-identical to upstream google/gemma-4-26B-A4B-it once
trailing newlines are normalised — and it permanently closes the class of bug
found while staging the control: the A16 build ships a stale 266-line template
against upstream's 390, with the thinking path built differently and no
`thinking` property in its tokenizer_config response_schema. Serving each build
with its own template would have moved a second axis.

The control ran on the operator's greenlight and has been reverted. Seat is back
on the W4A4 build, healthy, RestartCount 0, both aliases verified through the
gateway — char-rp returns content with reasoning_content empty,
char-rp-reasoning returns both.

Result, since it settles a question this repo's config now encodes: activation
precision does NOT explain the contradiction-detection deficit. Contradiction
detection moved 12% -> 19% between W4A4 and W4A16, which at n=16 is 2/16 -> 3/16
— one item — against gen's 81% on identical items. Every other task is identical
across the two builds and the core difference is 2.6 points carried almost
entirely by two single items. brokkr-smithy-dev pre-registered that a null
result would be the robust branch, because a hidden third axis would tend to
create a delta rather than suppress one, so the conclusion survives the residual
doubt neither side could close without a dequantization pass.

The practical upshot for future scheme choices: W4A4 costs less on this workload
than the caution warranted. The caution was still correct to have.

Displaced production for 3.7 seconds of measurement plus two container
recreates. The A16 build and the BF16 tuning base both stay on disk with the
runbook in the stack README, so re-running is a two-minute flip.
 2026-08-24 13:03:19 -07:00
vh 1bd90eaacc docs(gemma4-charrp): stack README — the three model dirs, the A16 control runbook 
The stack had no README and now carries three model directories that look
interchangeable and are not: the BF16 QLoRA base that cannot be served here, the
W4A4 quant that is served, and the W4A16 build that exists solely as an
activation-axis control. Writing down which is which, and why, before someone
"simplifies" the compose to the BF16 path and rediscovers the OOM.

Also captures the A16 control procedure end to end, including the two confounds
found while staging it — the two Hub repos named NVFP4A16 that declare 4-bit
activations, and the stale chat template the real one ships — and the fact that
overriding the template is safe because the tokenizers are identical. Both sides
have now cross-checked this: brokkr independently diffed every non-quantization
config field of both builds against the upstream BF16 and found only
transformers_version differing. Residual risk recorded rather than hidden:
config identity is not weight identity and nobody has done a dequantization
pass.

The Gemma-4 flags are documented as architecture-level rather than
checkpoint-level, since that is why they survived the seat swap unchanged, and
the enable_thinking:false pin is called out as mandatory rather than stylistic —
without it every plain prose turn lands in reasoning_content with a null content
and every consumer breaks.

Notes the non-termination defect with thinking on (32 of 96 calls truncating at
12k tokens, all 16 constraint items among them, reasoning sound right up to the
point it fails to stop) and why VLLM_USE_V2_MODEL_RUNNER=0 is deliberately not
applied to a seat whose production mode is thinking-off.

No live change: the seat is still serving the W4A4 build. Displacing it for the
control run is an operator decision and is still open.
 2026-08-24 12:34:50 -07:00
vh 24e8826219 docs(gemma4-charrp): the A16 control needs a chat-template override, not just a path swap 
Pre-flighting the staged A16 build before handing it to brokkr-smithy-dev's
battery found a second axis hiding inside what was supposed to be a
single-variable control.

The A16 build ships a STALE chat template. Verified by hash against the upstream
weights on the same disk: google/gemma-4-26B-A4B-it is 390 lines, the RedHatAI
A4 build's is 389 and byte-identical to upstream once trailing newlines are
normalised, and the prithivMLmods A16 build's is 266 and is not. The delta is
not cosmetic — upstream and A4 open the thinking path with
`{%- set enable_thinking = enable_thinking | default(false) -%}` and branch off
it, while the A16 template has no such set and guards with
`enable_thinking is defined and enable_thinking` instead. tokenizer_config.json
corroborates: A4's response_schema carries a `thinking` property, A16's has only
role and content. That build was quantized from an older revision of the
checkpoint.

Served with its own template, the A16 arm would render a different prompt for
identical messages, and a contradiction-detection delta could be attributed to
activation precision when it was the template. That is the same failure class as
the misnamed-A16 repos — a field nobody validated, believed because the name
looked right — one layer further down, and it would have produced a result that
looked like a finding.

Overriding is safe because the tokenizers agree: vocab identical at 262,144
entries, added_tokens identical, so the same template over the same vocab
renders the same token ids. Everything else pre-flights clean — both artifacts
complete with no missing shards, generation_config.json byte-identical.

Seat NOT flipped; displacing production for the bench window is the operator's
call and is still open.
 2026-08-24 12:32:03 -07:00
vh f509668e45 docs(gemma4-charrp): record the A16 activation-axis control and how to run it 
brokkr-smithy-dev's first battery on the new seat scored 12% on contradiction
detection with CoT off, against gen's 81%, while state tracking, deterministic
constraint following, long-context state and the confabulation control all sat
at 100%. That is not general degradation — it is the shape 4-bit input
activations produce on the most reasoning-dense task, which is exactly the
confound flagged when the W4A4 quant was chosen. They have recorded the finding
as CONFOUNDED rather than reporting it as a property of Gemma, and asked for an
A16 build to separate the two.

No quant run was needed: a genuine A16 build of the same checkpoint already
exists on the Hub and is now at /tank/aimodels/gemma4-26b-a4b-it-nvfp4a16
(prithivMLmods, compressed-tensors, nvfp4-pack-quantized, input_activations
null, 17 GB). Same weights, same loader as the live seat, one axis moved.

⚠ Two other repos would have answered the question wrongly and the note in the
env template says so: bg-digitalservices and ManniX-ITA both publish
"Gemma-4-26B-A4B-it-NVFP4A16" whose config declares input_activations num_bits
4 — W4A4 under an A16 name, via modelopt, both 16.46 GB against the real one's
17.93. Using either and seeing T2 stay at 12% would have wrongly convicted the
model.

Running it is a one-line GEMMA4_MODEL swap plus a recreate, because there is no
room for a concurrent seat: GPU0 has 3.5 GiB free with gen and the A4 seat on
it, and GPU1's 19.4 GiB against ~18 GiB of weights is the same sub-GiB headroom
that crash-looped the predecessor this morning. Port and both aliases are
unchanged either way, so no consumer config moves.
 2026-08-24 12:28:17 -07:00
vh 27155c0f3b feat(char-rp): swap the seat to the Gemma-4 26B-A4B MoE, NVFP4, same port 
Straight-across replacement of the dense G4-MeroMero-v2-31B-NVFP4A16 seat with
google/gemma-4-26B-A4B-it on ana-ml2 GPU0. Port, served-model-names and every
gateway route are unchanged, so no consumer sees a difference in addressing:
`char-rp` -> hosted_vllm/char-rp and `char-rp-reasoning` ->
hosted_vllm/char-rp-thinking, both still :8016. The seat's requirements now
include chain-of-thought, which makes throughput more critical rather than less
— the user waits through the whole reasoning block before the first visible
token, and the MoE measures ~114 tok/s @32K against the dense 31B's ~40.7.

Both artifacts are on disk and they are NOT interchangeable. The BF16 weights
(/tank/aimodels/gemma4-26b-a4b-it-bf16, 49 GB) are the QLoRA tuning base, since
QLoRA does its own quantization. They CANNOT be served here: 48.10 GiB of
weights against ~49 GiB of free GPU0 leaves nothing for KV cache, and the
engine would die at allocation exactly the way the predecessor did this
afternoon. The serving copy is RedHatAI/gemma-4-26B-A4B-it-NVFP4 (16 GB),
chosen over the other -it quants because it is compressed-tensors
(nvfp4-pack-quantized) — the same loader path the outgoing seat used — from the
llm-compressor team at 357k downloads. The nvidia/ repo is the base rather than
-it, and the thinking channel lives in the instruction-tuned weights.

Smaller weights at the same 0.47 memory budget buy a much larger KV pool:
27.37 GiB and 1,724,110 tokens, against the predecessor's 371,023 at the same
budget. That is 6.5 full-length 262K sequences concurrent rather than 1.4.

The gemma4 tool-call parser, reasoning parser and the enable_thinking:false
default all carry over unchanged — they are architecture-level, not
checkpoint-level. The --chat-template override does NOT carry over: MeroMero
pointed at a jinja hand-patched against that checkpoint, and this model ships
its own. Verified that dropping it did not reintroduce the failure that flag
existed to prevent — non-thinking prose lands in content with reasoning_content
empty, and the thinking alias populates reasoning_content with content
carrying the answer.

⚠ Scheme differs from the incumbent and the bench should say so: this quant
declares 4-bit input activations (W4A4) where the outgoing seat was NVFP4A16.
Faster, and not like-for-like on the activation axis.

meromero-charrp is retained stopped in `created` state and relabelled to
AI - Dormant, per the house rollback pattern. Both stacks want :8016, so
rolling back means stopping the gemma4 seat first.
 2026-08-24 12:02:59 -07:00
vh 850e0c3351 fix(meromero-charrp): drop GPU0 budget to 0.47 — the seat was OOM crash-looping 
`vllm-meromero-rp` had been restarting since 2026-08-24 18:2x, 13 times by the
time it was looked at, taking both the `char-rp` and `char-rp-reasoning`
gateway aliases down with it (they resolve to the same seat on :8016 —
hosted_vllm/char-rp and hosted_vllm/char-rp-thinking).

Root cause is CUDA OOM on ana-ml2 GPU0, which the startup logs hide well: the
engine gets through weights, torch.compile and CUDA-graph capture looking
entirely healthy, then dies at KV-cache allocation with
`torch.OutOfMemoryError: ... 195.19 MiB is free`.

GPU0 is shared with `vllm-gen`. gen is configured at 0.43 but actually holds
~45.6 GiB of the 94.97 GiB card, because --gpu-memory-utilization sizes the KV
cache and does not account for CUDA context, graphs and non-torch overhead.
This seat was at 0.51, so the pair was committed to 0.94 of the card with about
0.6 GiB of real headroom. That fit on 08-21 and stopped fitting today.

0.47 restores ~4.8 GiB of margin and costs nothing usable: KV cache 27.36 ->
23.56 GiB, 430,825 -> 371,023 tokens against a max-model-len of 262,144, so the
pool still holds 1.4x a full-length sequence. What is lost is concurrent long
requests, not context.

Verified through the gateway rather than at the container: char-rp returns 200
with content, char-rp-reasoning returns 200 with both content and
reasoning_content populated. Seat is healthy with RestartCount 0.

The arithmetic and the "check used_memory, not the flag" warning are written
into the env template, because the next person to raise either budget needs to
lower the other in the same change.
 2026-08-24 11:42:36 -07:00
vh 35adc4a043 feat(homepage): rebuild on Australis Skyfall — dual theme, light mode shipped 
The board was on the Australis TERMINAL palette, which is dark-only by design
("Always dark first. No light mode in this system"). Skyfall is the dual-theme
web derivative of the same science, and its bundle turned out to be sitting in
this repo's own git history: a predecessor vendored it on 2026-08-19 and a
later commit deleted it. `git show 45c1995:...` returns colors.css with both
`:root` (dark) and `[data-theme="light"]` (Skyfall Day) intact, plus the
calm-depth layout tokens, the typography scale and Supreme 400/500/700. So the
light ramp is canonical rather than derived, which was the entire objection to
building one.

The visual language moves with the palette. Depth is now the recipe and not a
choice — every elevated surface carries a 1px hairline AND a two-layer shadow,
never one without the other. Radii move to Skyfall's scale, cards at
--radius-lg. Widget stat values move from the display face to mono, because
Skyfall is explicit that numbers and telemetry are always --font-mono. The
full-width aurora ribbon under the tab bar is gone: Skyfall sanctions exactly
two accent expressions, the active rail and hero-only glows, and a decorative
gradient across the chrome is neither — so the colour it carried now lands on
the active tab as a 2px accent bar plus an --accent-soft fill, which is the
rail. Every binding is written against the semantic layer; there are no raw
family tokens and no colour literals left in our own file.

build.py now guards the vendoring instead of advising it. The three token files
are hashed and a mismatch FAILS the build — a vendored file is either
byte-identical to the bundle or it is a fork wearing the bundle's name, and the
theme this one replaces had to be torn out twice for exactly that.

⚠ Homepage's own theme toggle is unreachable, and reaching for it breaks the
dashboard. It renders only when settings.yaml leaves `theme:` unpinned, and
with the key absent the page's data loader throws and its catch branch serves
`initialSettings: {}` — no tab bar, no layout, no i18n. Six force-recreates
over seven minutes all came up empty; restoring `theme: dark` rendered
correctly on the next recreate in 12 seconds, while /api/services returned 200
with fully correct content the whole time. That is the first confirmed cause of
the long-running "tab bar goes missing after a recreate" symptom, and it also
retires the homepage.log-size lead recorded earlier today: rolling the log
aside did nothing during this episode, so that coincidence was intermittency.

So the toggle is ours. conf/custom.js renders it and stores the choice;
build.py re-emits each vendored light block twice, once for an explicit
`data-theme` and once inside a prefers-color-scheme media query scoped to
`html:not([data-theme="dark"]):not([data-theme="light"])` — that :not() pair is
what lets a stored dark choice survive a light-mode OS. Verified against both
OS preferences: load, click, click back, reload, all four correct. `data-theme`
is the control surface; Homepage's own `dark` class stays on <html> and does
not fight, because our rules carry !important on the surfaces Tailwind's
`dark:` variants would otherwise claim.

Two font substitutions, both documented rather than silent: Space Grotesk for
Bespoke Sans and JetBrains Mono for Victor Mono. Only Supreme was ever vendored
here and Skyfall's own notes call Victor Mono user-supplied, so this is a
two-line swap when the real faces arrive.

Dark and light, all four tabs: http://10.100.10.50:8090/b/homepage-skyfall/

vh 39da1d4a97 feat(homepage): recategorise on "do I open this?", collapse the API groups 
The board mixed tools with endpoints. A vLLM seat whose href is a /docs page
sat in the same band as ComfyUI; the MQTT broker and the RustDesk relay, which
have no page at all, sat in Apps; and `Service Networking` was thirteen members
spanning three AdGuards, five Dockges, two Traefiks and four headless agents.

Every group is now one of two kinds and they never mix. TOOLS are expanded and
sit at the top of their tab. ENDPOINTS — an API, a broker, a background agent,
an href that is /docs or /ping or nothing — carry `initiallyCollapsed: true`
and sit at the bottom. Collapsed is not hidden: the eyebrow and its rule still
render, so the tab still says the thing exists and one click expands it.

A second rule fell out of the same pass and now shapes the group boundaries: a
group's members should all carry a widget or none should. A stat strip makes a
card ~50px taller, so one widget card in a row of plain ones opens a void under
the plain ones. That is why AdGuard and Traefik get their own groups rather
than sharing one with Dockge, and it is most of why the old Service Networking
band looked broken. AdGuard (ANA) was the last short card in its row and now
carries the same query/blocked/latency strip as its two siblings — one
infra-ops AdGuard login authenticates against all three instances, verified
against each; it lives in that stack's .env on the host and is vaulted.

The sixteen GPU-backed model seats were deliberately NOT relabelled.
`homepage.group` is read at container creation, so clearer names for
`AI - Inference` and friends would have cost a recreate on six vLLM seats, four
eval seats and four TTS engines — multi-minute model reloads on endpoints peers
reach through the gateway. Order plus `initiallyCollapsed` buys the same
separation for nothing, so those names stay as they are on purpose.

28 containers that ARE cheap to bounce were relabelled, across five hosts, via
rerunnable elway playbooks. Their label steps are gated on the old value still
being present, so a second run reports skipped rather than churning. Two verify
steps were wrong on first contact and are fixed with the reason recorded: the
traefik check raced its own recreate, and asserting a model seat is "running"
cannot answer "did I bounce it" when a seat may be legitimately stopped —
container age can, and now does.

The canonical stacks/ tree was synced to the deployed labels afterwards, so
intent and reality agree again on all fourteen tracked stacks.

Also documents the real nature of the post-recreate blank dashboard, which cost
~25 minutes here and an hour on 2026-08-19. `initialSettings":{}` in the served
HTML is the catch branch of the page's data loader, not a warm-up and not a
cache — and the error can vanish entirely, because the logger is assigned inside
the same try and the catch only logs if the logger exists. Ruled out by
measurement this time: all four API routes return 200 with correct content while
the page serves {}, and the previous known-good settings.yaml reproduces it
identically. The README now carries the one-command test and the next lead.

Before/after, all four tabs: http://10.100.10.50:8090/b/homepage-relayout/
 2026-08-24 08:54:06 -07:00
vh f6f2f69649 fix(homepage): uniform 4-column grid, hold the status gutter, unleak AI Systems 
The board's card width changed at every group boundary because `columns:` was
being tuned per group under the 2026-08-18 "columns = member count" rule. That
rule is retired: it sets `lg:grid-cols-N` for one group, so it fixes that
group's CARD WIDTH, not its density. Measured on the live board, Notes rendered
a single 1464px card, News and Media 728px, Eval & Retrieval 286px, everything
else 360px. All 20 groups are now `columns: 4` and every card renders at 360.

`.service-name` reserved a 78px status gutter with `padding-right` and relied
on `overflow: hidden` to hold it, but overflow clips at the PADDING box — the
gutter was spill room the title printed straight through. Six cards on the AI
tab rendered their name underneath their own status pill, measured by testing
the title text node's box against the status cluster's. The intended ellipsis
never fired either: it is painted by whichever block's own line overflows, and
that is the anonymous box around the bare title text node, which does not carry
`overflow`. The gutter holds by wrapping now, and the description opts back out
of it with a negative margin since the pill only ever covers the first line.

Scriberr's `homepage.group=AI Systems` named a group absent from `layout:`, so
it had no `tab:` and rendered on all four tabs — the same defect as UltraSeedbox
in 2026-08-18, arriving this time from a container label. Relabelled to
`AI - Audio Tools`, where the other ASR seats already live. The
`homepage.group=AI Systems` sample in the repo-root CLAUDE.md was the source of
the name and now carries the constraint, plus the fact that a labelled
container is discovered from any of the five configured engines and must not
also be listed in services.yaml.

Also: descriptions clamped to three lines so a five-line outlier stops dragging
its row 50px taller than its neighbours; icon ramp overridden off slate-400 ->
slate-700, which was sinking the bottom half of every glyph into the card fill;
bookmark groups and Jellyfin's trailing stream rows brought into the card and
eyebrow vocabulary; group gap 10px -> 22px now that width no longer separates
them.

The icon override sits on `html[class]`, not `:root`: Homepage sets the same
variables on `.theme-slate`, which is on the <html> element, and a class beats
`:root` on the same element.

Verified with Playwright against the live board — per-group card width, card
height spread, and a geometric title-vs-status collision check, before and
after. Before/after captures: http://10.100.10.50:8090/b/homepage-relayout/

vh 32349b7653 memory: snapshot — Anaheim tunnels on AES-128, ana-gw admin closed, Scriberr live, ESH DNS fixed 
Rewrites the in-flight section, which had gone stale in one place
(speaches is stopped, not live) and did not reflect a session in which
everything opened was also closed. Three detail files carry the bulk:
the FortiGate's public surface reduced to nothing including the ACME
listener, Scriberr's deployment and the three upstream defects it
required working around, and the ESH DNS repair that also made the
IPv6 naming scheme real on three hosts.

The tunnel entry in the decisions log described a cipher change as
proposed and pending; it has since been attempted, found impossible in
the form intended, and resolved differently, so the line now points at
the outcome rather than the intention.

New decisions cover the cipher adoption and the finding that the
per-flow ceiling belongs to the UniFi gateway's software cipher rather
than the firewall, the administrative closure, the transcription
deployment, the DNS repair, the retirement of an ASR service whose
only consumer was abandoned, and a database VM that until now had no
fleet identity and no vaulted credential at all.

Three approaches are recorded as abandoned: an AEAD cipher the far end
cannot express, an upstream DNS setting the gateway accepts and
ignores, and a scheme to claim unused delegated prefixes that founders
not on the prefixes but on having to rebuild a firewall policy to use
them.

vh d419b11d43 docs(ipv6): close the NH3 multi-prefix question by operator ruling 
The gateway has no IP-passthrough mode, confirmed by the operator with
admin access to it, so the inexpensive path of letting the UDM take the
delegation whole and carve it natively is unavailable at this site.

What remains is a separate DHCPv6 client presenting several identities,
which needs recabling to reach the gateway, splits routing so that one
device handles v4 and another v6, and above all moves IPv6 off the
UDM's zone firewall, leaving the entire policy to be rebuilt elsewhere
before any host could safely hold a globally routable address. The
operator has declined it and the LANs stay without v6.

The index entry also still asserted the superseded single-delegation
conclusion as fact; it now carries the corrected reading alongside the
ruling, so the finding and the decision not to act on it arrive
together rather than the first inviting a retry of the second.
 2026-08-24 07:05:49 -07:00
vh bd209951ac docs(ipv6): correct the NH3 delegation finding — eight /64s, not one 
The note concluded AT&T delegates a single /64 and that reading the
address pattern as a /60 was a mistake. A later finding in the same
session overturned that by reading the BGW's own statistics page, and
that correction was never written down; it survived only in the
transcript and surfaced again while assessing whether more prefixes
could be claimed.

The gateway holds the /60 and rations it, keeping half for itself and
delegating the top eight /64s one at a time. Both observations agree:
a prefix-id only carves within a delegation already held, so the
earlier test could not have moved a lone /64 regardless. The limit is
that UniFi solicits once, which makes the requester the ceiling rather
than the carrier.

vh d127e29fac docs(ipv6): retire the next-candidates line now that all three are done 
Replaces it with why the remaining segments have no eligible hosts:
two are appliance-only and three have no IPv6 enabled yet, pending the
firewall-policy pass that SLAAC on a client segment would require.
 2026-08-23 22:39:51 -07:00
vh 4e83395ddf docs(ipv6): all three esh-server hosts now carry the segment name 
esh-pve-nas and esh-vm-db join esh-docker-vm on 4411:b105, at
:50:55 and :50:60 respectively, each applied by the same prefix-deriving
if-up.d hook so the last two groups read straight off the IPv4 address.

Two obstacles are recorded because both will recur. The Proxmox node had
link-local only despite every relevant sysctl appearing correct, because
its bridge carries per-interface forwarding and the kernel ignores router
advertisements on a forwarding interface unless accept_ra is explicitly
two rather than one. The fix takes the advertised prefix while declining
the default route, so the hypervisor gains an address without any change
to how it routes; this was verified after applying, with the v6 default
route count still at zero.

The database VM refuses key authentication for the privileged accounts
and its unprivileged login cannot escalate without a password, so the
hook went in through the QEMU guest agent from the hypervisor, which
executes as root inside the guest. The document notes the base64
indirection needed to get a multi-line script through intact.

vh ffb7fba346 docs: give the ESH IPv6 naming scheme a home, and make it real on one host 
The scheme has existed since August as a single line of persistent
memory, which a snapshot then deleted. It is a naming convention
rather than temporal state, so it now lives in docs/pfi as a proper
document, and the memory entry is reduced to a pointer at it. The
document carries the full table, the address structure, the reasoning
about which slots can and cannot hold a name, and the recipe for
applying one to a host.

It also corrects the conclusion the original note ended on. That note
held that these names could never appear on the wire, which is true
of everything UniFi is able to assign but not of what a host can
assign to itself, and the distinction is the whole difference between
a joke and an address.

AdGuard on esh-docker-vm now holds the esh-server name, at
2607:73c0:402:1d02:4411:b105:50:45, where the segment identity and the
IPv4 address are both legible. It is applied by an if-up.d hook that
derives the prefix at runtime rather than hardcoding it, backgrounds
itself with a retry so it cannot stall interface bring-up, and adds
nothing to the existing interface configuration.

This is load-bearing rather than decorative. The gateway advertises an
IPv6 resolver to clients, macOS prefers it over the IPv4 one, and it
previously pointed at an address derived from that host's MAC.

vh 41091eef8f docs: restore the ESH IPv6 naming scheme, dropped by a snapshot 
The six ESH LAN hexspeak names were recorded in fe3d765, refined in
959bb6e and 8be8a51, and then removed without comment by the memory
snapshot in 837fa36. Nothing referenced them afterwards, so the loss
went unnoticed until the operator asked for them tonight and no file
on the machine contained the string.

Recovering it was harder than it should have been, for a reason worth
recording: the table was written in uppercase and git log -S is
case-sensitive, so a history search that would otherwise have found it
immediately came back empty. The entry was eventually located in a
session transcript, which named the commit.

The restored text carries the original verbatim plus two additions. It
is marked as a naming convention rather than temporal state, since
that is what made it eligible for pruning in the first place. And its
conclusion that the names can never appear on the wire is corrected:
the reasoning holds for what UniFi can assign, but a Linux host can
take such an address itself, which was verified on esh-docker-vm along
with a persistence path that leaves the existing interface config and
SLAAC untouched.

The scheme's first practical use is noted against the resolver address
the ESH gateway now advertises, which currently depends on a MAC.

vh 6217d3993e fix(scriberr): force uv to copy rather than reflink when building envs 
Scriberr builds each model backend's Python environment with uv at
container start. uv's default link mode reflinks or hardlinks out of
its cache, which fails on this overlayfs over ZFS combination and
reports it as a failure to clone a metadata file with errno 11,
resource temporarily unavailable. The wording points nowhere near the
cause.

The damage was partial and therefore easy to miss: WhisperX and
PyAnnote came up fine and the application served normally, while the
Parakeet and Sortformer backends were quietly absent. Setting
UV_LINK_MODE to copy trades a little disk and build time for
environments that actually materialise, and the occurrence count for
that error is zero on the following start.

The knob is exposed through the environment so it can be moved back to
the default if a future host does support reflinks.
 2026-08-23 19:31:54 -07:00
vh efddb4e511 feat(scriberr): stand up transcription on ana-ml2, pinned to GPU1 
Scriberr transcribes audio and video locally with WhisperX and
speaker diarization, and it lands on ana-ml2 rather than ana-docker
because the work is GPU-shaped: ana-docker offers eight cores already
shared with fifty containers and thirty-seven gigabytes of disk,
against ninety-six cores, terabytes on /tank and idle capacity on
GPU1. The reservation names device 1 explicitly, since GPU0 is fully
committed to the gen seat, and the container is confirmed to see that
card alone.

The image is built from source, which is not a preference. These are
Blackwell cards at sm_120; the published CUDA image covers Pascal
through Ada only, and the blackwell image the upstream README
documents has never been published at all. The path upstream actually
ships for sm_120 is Dockerfile.cuda.12.9, carrying CUDA 12.9 and cu128
torch, so that is what gets built. The compose header says so, because
the obvious cleanup is to swap in the published image and that would
silently drop the deployment to CPU.

Two configuration details are load-bearing and documented where
someone would go to change them. The application runs as uid 10001
rather than the usual 1000: that Dockerfile moves its user aside for
Ubuntu 24.04's own uid-1000 account and chowns /app accordingly, while
the entrypoint's remapping covers only the data directories, so at
1000 the process cannot open its database and restarts forever behind
a SQLite error that reads as though the machine were out of memory.
Secure cookies stay off while the service is reached over plain HTTP,
or sessions are dropped by the browser and login appears to loop for
no visible reason.

Storage is bind-mounted onto /tank because model weights run to
several gigabytes and the root pool on that host is nearly full.

Also adds the scriberr service alias to internal DNS, following the
existing alias convention so consumers name the service rather than
the box.
 2026-08-23 19:28:33 -07:00
vh 22ae9cd480 ops(ana-gw): disable ACME and retract the all-port VIP claim 
The ACME client is unbound from wan1, which removes the HTTP-01
challenge listener that had been holding port 80 open irrespective of
allowaccess. An external sweep of fifty-five ports against the WAN
address now finds nothing open at all, while the internal interface
still serves the GUI and SSH and retains its certificate, which
remains valid until late October and simply stops renewing.

The previous note's claim that four virtual IPs were unrestricted
all-port static NATs is withdrawn. A FortiOS virtual IP can be scoped
either by an explicit forwarded port or by a service binding on the
object, and the earlier parse inspected only the former. All four use
the latter, and the custom services behind them are narrow. None of
the fourteen is unrestricted.

Ground truth from outside is recorded in place of further config
reading, listing what each public address actually exposes. Three
configured mappings answer nothing at all and are noted as tidy-up
candidates for the migration rather than as exposure.
 2026-08-23 16:02:20 -07:00
vh f39b66d2e1 ops(ana-gw): port 80 on the WAN address is the FortiOS ACME listener 
The previous note attributed the open port to an ISP transparent
proxy. That was wrong. It terminates on the FortiGate: system acme is
bound to wan1, and FortiOS opens port 80 there to answer HTTP-01
challenges regardless of what allowaccess permits, which is why the
port stays open with the interface set to ping only. Every
non-challenge request returns a fixed 403 whose body reads ACME Access
Only. No DNAT is involved; of the fourteen virtual IPs only two land
on that address, neither on port 80.

The wrong conclusion came from a sniffer filtered on dst host, which
matches inbound packets alone and so excluded the replies being looked
for. Filtered bidirectionally the box is plainly seen emitting SYN-ACK
on port 80. The note records the rule.

Two consequences follow. The earlier warning that certificate renewal
would fail without http in allowaccess is retracted, since FortiOS
opens the challenge port itself. And the listener is not an
administrative surface, though its value is now marginal with WAN
administration closed, so the note records how to remove it and leaves
that decision open.

Also captured: four virtual IPs are all-port static NAT and map every
port of their external address.
 2026-08-23 15:53:55 -07:00
vh 7bc9754e40 ops: adopt AES-128 on both Anaheim tunnels and close public admin 
Both tunnels now negotiate AES-128 for ESP, applied make-before-break
so neither dropped waiting on its far end: the FortiGate was widened
to accept the new cipher alongside the old one first, then each UniFi
gateway was flipped. Single-stream throughput moves from 245 to 270
on the NH3 tunnel and from 268 to 304 on the ESH tunnel. Both network
objects were diffed against pre-change snapshots and the only field
that moved on either is the ESP cipher.

The proposal lists are left accepting AES-256 as well. The peers offer
only AES-128 so the extra entries are inert, and retaining them means
a gateway reverting cannot strand a tunnel.

With that up, the WAN administrative surfaces are closed. The
interface is back to permitting only ping, and the infra-ops account
is again restricted to RFC1918 space. Ports 443 and 22 were confirmed
closed from two separate sites and management over the tunnel still
works. The close was issued over the tunnel rather than over the WAN,
since withdrawing SSH from the interface while connected through it
would sever the session mid-command. The box now has no out-of-band
path, which the memory records explicitly.

Also captured: the two UniFi vault items have different shapes, one a
bare key and one a documentation note requiring extraction, which
produces an opaque nginx rejection if missed, and the ESH key's first
confirmed write.
 2026-08-23 15:44:32 -07:00
vh 6edebe4864 ops: forwarding through a downstream WireGuard terminator is free 
FortiOS has no WireGuard, so any WireGuard site-to-site has to
terminate behind the edge, and ana-wg already fills that role. The
earlier 767 Mbit/s figure was taken with traffic terminating on that
box, which left the forwarding case unmeasured and overstated what a
real deployment would see.

Measured properly, transit from NH3 through the tunnel and onward to
ana-docker returns 763.8 Mbit/s on one stream and 790.4 across eight,
so the forwarding hop costs nothing and the full threefold gain over
IPsec survives. The container uses around a fifth of four cores at
that rate, against the UniFi gateway spending a third of its own four
to move a third as much.

The note records what still needs deciding rather than presenting this
as ready to build: Anaheim hosts have to route to the terminator
directly or pay a hairpin through the edge, which was not measured;
the terminator introduces a failure mode the edge did not have, with a
fallback route as the mitigation; and the NH3 end needs its own
terminator, where a Linux host matches the measured figure while the
existing UniFi WireGuard server would likely land lower.

The test tunnel, its peer and the temporary route were all removed.
 2026-08-23 15:25:05 -07:00
vh 062215e81a ops: the tunnel's per-flow limit is the UDM's software AES-CBC 
Varying only the cipher settles what inference could not. AES-128 has
ten rounds against AES-256's fourteen, so a software-bound path must
speed up when the cipher gets cheaper while a hardware-offloaded one
will not move. Run as A/B/A on a single stream, AES-256 returns 232,
245 and 243 Mbit/s and AES-128 returns 282 and 275, a gain of about a
fifth at identical CPU. The FortiGate's offload engine is therefore
not the constraint, and the operator's reading of the UniFi side as
software crypto without acceleration is correct.

Two earlier claims of mine were wrong and are corrected in place. The
observation that the UDM sat at seven percent CPU was a sampling
artifact, since UniFi refreshes that statistic on the device report
interval and the windows used were four seconds; a sustained run reads
thirty-five percent, around one and a half of four cores. The
per-session offload hypothesis is refuted rather than merely unproven,
because it predicts no response to a cipher change.

The remaining figures follow from this. One stream is one core, eight
streams engage about three, and aggregate stops responding to cipher
choice once several cores are working because the path bounds it. CBC
chaining is what makes this expensive, as it serialises blocks and
prevents the AES instructions from pipelining, which is also why the
same gateway manages far more over WireGuard.

The cipher was restored and the network object verified unchanged
against its pre-test snapshot.
 2026-08-23 15:11:51 -07:00
vh 8ecffa1fab ops: WireGuard over the same path carries one stream at 767 Mbit/s 
The operator asked for a WireGuard test between ana-wg and NH3 across
the public internet, which is the arrangement that separates the path
from the crypto since neither gateway performs encryption in it. A
single stream returns 767 Mbit/s against 245 for IPsec over the same
wire, and eight streams return 763, so one flow already saturates the
path and there is no per-flow penalty whatsoever.

That settles several things at once. The limit is not the circuit,
the NH3 uplink, the ISP or the physical path, all of which carry 767
on one flow. Ranking the implementations, Linux WireGuard shows no
per-flow penalty, UniFi's WireGuard shows roughly 1.4x, and IPsec on
this pair shows 2.8x. Latency under a single bulk stream tells the
same story, rising to 12.7 ms on WireGuard against 102 ms on IPsec.

This overturns the earlier conclusion that changing transport was not
worth pursuing, which compared eight-stream figures and so understated
the gap for single-stream work by a factor of three. A WireGuard
site-to-site terminated on ana-wg now looks worth considering, and the
note records the open questions around failover and policy.

Attribution between the FortiGate and the UniFi gateway remains
unresolved, since both perform IPsec in the slow measurements, but the
remedy does not depend on which one is responsible.

The test tunnel was removed, ana-wg is back to its original three
peers and the generated keys were shredded.
 2026-08-23 14:57:29 -07:00
vh d42e9d8712 ops(ana-gw): establish the per-flow cap is IPsec-specific, not capacity 
The operator asked whether the 80F is simply out of capacity. It is
not. Routing a single flow between two Anaheim VLANs through the same
box, with no tunnel involved, sustains 940 Mbit/s, which saturates the
link, and eight flows over that path return the same figure. There is
therefore no per-session ceiling in the plain forwarding path and the
roughly 250 Mbit/s per-flow limit belongs to the IPsec datapath alone.

Measuring the second tunnel with the same probe supports this. The ESH
side, terminating on different gateway hardware at nearly half the
round-trip time, returns 268 Mbit/s on one stream against NH3's 245,
and 715 against 692 across eight. A window-limited path would have
been substantially faster at the shorter round-trip, so the agreement
between two dissimilar far ends is further evidence of a rate cap.

This also corrects the previous note, which named the FortiGate on
reasoning that could not separate the box from the protocol, since
every slow path was both. That separation is still not established:
both tunnels terminate on UniFi gateways running common firmware, so
the cap could belong to either side. The note records the tunnel
topology that would decide it and flags the bearing on the pending
replacement.
 2026-08-23 14:48:34 -07:00
vh cf0cb2cbb3 ops(ana-gw): pin down what limits a single stream across the tunnel 
The earlier note described the constraint as per-flow serialisation
without evidence. Pinning SO_SNDBUF and sweeping it shows what it
actually is: throughput holds flat between 224 and 247 Mbit/s across
a thirteenfold range of in-flight data while round-trip time scales
with the buffer instead, from 7.8 ms up to 107 ms. Retransmissions
are absent throughout. That is a fixed service rate with a standing
queue ahead of it, so socket buffer, window scaling and congestion
control are not the lever and should not be pursued.

The same measurements surface something with wider consequences than
throughput: a single bulk stream lifts tunnel latency from 6.9 ms to
102 ms average, 136 ms peak, with no loss. Interactive traffic
sharing the Anaheim link degrades sharply whenever anything moves
bulk data, and parallelising transfers makes that worse rather than
better.

Localisation rests on the FortiGate appearing in both slow paths and
in neither fast one, with aggregate throughput over the same security
association reaching 692 Mbit/s. Per-session NPU offload fits the
shape but was not confirmed on the device; the note records the test
that would settle it and flags the bearing this has on the pending
FortiGate replacement.
 2026-08-23 14:42:17 -07:00
vh e41d19f1cb ops(ana-gw): close out the Anaheim tunnel cipher question 
The AES-GCM cutover was authorised and attempted, NH3 side first. It
cannot be completed: UniFi's manual site-to-site IPsec implements no
AEAD cipher. Eight GCM spellings were rejected with
api.err.InvalidPayload while an otherwise identical body carrying
aes256 returned rc:ok, which isolates the enum rather than the
request as the cause. The accepted set is aes128/aes192/aes256/3des.
Both Anaheim tunnels terminate on UniFi gateways, so this blocks the
ESH tunnel on the same grounds.

Measuring while testing also retires the premise. NH3's uplink is a
1 Gbps link, so Anaheim's 2 Gbps circuit was never the relevant
ceiling, and the tunnel sustains 692 Mbit/s across 8 streams rather
than the ~550 previously recorded from a 4-stream run. Compared with
WireGuard over the same gateway and uplink, the deficit narrows from
2.3x at one stream to 15% at eight, so moving this link onto a
different transport is not worth doing.

The constraint is per-stream, around 245 Mbit/s, with both endpoints
idle under load. Parallelising bulk transfers remains the mitigation
and is worth 2.8x at no cost; NFS nconnect is the equivalent lever
for single-stream mounts such as /mnt/smithy on ana-ml2.

FortiGate phase2 for pfi-ana-nh3 keeps the widened proposal list,
which is inert while the peer offers only CBC and avoids a further
renegotiation. The UDM network object was diffed field-by-field
against its pre-change snapshot and is unchanged.
 2026-08-23 14:29:17 -07:00
vh 5af362e9d0 ops(ana-gw): restore WAN admin access ahead of the FortiGate cutover 
Re-open the ana-gw admin GUI on wan1 so the Anaheim edge can be
managed remotely if the cutover goes wrong, reversing part of the
2026-08-12 lockdown. Two config changes, nothing else (verified by
diffing pre/post `show full-configuration`):

- wan1 `allowaccess ping https` — https only; http, ssh, and fgfm
  stay off, and wan2 is untouched.
- `infra-ops` trusthost widened to all routable IPv4; the `admin`
  account stays locked to 10.0.0.0/8 so the guessable username
  remains unreachable from the internet.

Verified end-to-end from two sites: a real `/logincheck` POST returns
AUTH OK over the public path, on a browser-trusted Let's Encrypt cert
for ana-fw.phasefinal.com valid through 2026-10-27.

Two FortiOS behaviours worth recording, both of which cost time here:
a trusthost whose base address is 0.0.0.0 is silently treated as
unset (so there is no writable "any" — only decomposed ranges), and
trusthost is enforced before the TCP handshake, so a blocked source
sees a filtered port rather than a refused login.

Follow-ons captured in memory, not actioned: ACME renewal for the
admin cert needs port 80 on wan1 (next attempt ~2026-09-27), and a
~5 SYN/s source in 179.51.184.0/21 now draws SYN-ACKs at no
measurable CPU cost.
 2026-08-23 14:03:40 -07:00
vh b6340519bc memory: snapshot — Anaheim tunnel at 25% of circuit; selene retired; hrafn CI fixed 
Session captured for a context reset. Six new detail entries.

THE OPEN ITEM: Anaheim's IPsec tunnel delivers ~550 Mbit/s aggregate against a
circuit measured at 2,153 Mbit/s. Not WireGuard (it is IPsec on ana-gw), not
CPU (idle), not crypto exhaustion (NPU-offloaded), not the fibre. Both tunnels
negotiate aes256-sha1; AES-GCM proposed. Operator signalled authorization;
execution pending, untracked by operator choice.

Also recorded: selene retired after losing a head-to-head on its own job with
chat-judge moved to gen and the model name left to 404; the 7-alias collision
on the gen seat that makes cross-alias corroboration an echo; hrafn adopted and
its CI found to have been reporting green while deploying nothing for its whole
life; all three Worldtree instances de-armed from a 69-day-stale :latest and
the Matrix homeserver re-plumbed to personal; every secret-bearing .env on
ana-docker tightened to 0600; the pfi org closing the repo-creation half of the
credential-migration directive; booth kept-board deletion and link pruning.

Two entries under Tried and abandoned: the CI checkout assertion that broke the
pipeline twice and was removed, and my proposal to alias a retired model name
at a different model, which the operator correctly overruled.

Index 271 -> 282 lines, under the 300 cap, so no archival fired.

vh 0ad332bb4a feat(booth): per-row link removal + render the link board as real UI 
The standing link board is the one MULTI-WRITER booth -- every agent session
appends operator-facing URLs to it. "Delete the folder" was the only
granularity available, so removing one dead link meant hand-editing markdown.
It is 32 rows and only grows.

  booth links                 row number, entry id, raw row
  booth unlink 3              by row number
  booth unlink 8b40e0a5       by entry id (what the UI's x posts)
  POST /b/<name>/unlink       form field `entry` = content id

ROWS ARE ADDRESSED BY CONTENT ID, NEVER BY POSITION. The board is append-only
and multi-writer: another session can post between listing it and clicking x,
and an index would then delete a neighbour. An id either matches the row you
saw or matches nothing. A row number typed at the CLI is resolved to its id
BEFORE anything is deleted. Appends and prunes now take the same flock on
.links.lock, so a post cannot be lost inside a prune's read-modify-write.

UI: a booth carrying links.md renders as rows -- description, URL, provenance,
copy button, per-row x -- instead of a markdown blob. links.md is filtered out
of the gallery so it does not appear twice; the header counts LINKS not files;
the empty-state and the one-click "Wipe now" both stand down for a board (same
rule as the kept lane: nothing durable is one click from gone).

booth/links.py extracted, STDLIB ONLY. The CLI needs this logic and must not
require the service venv -- importing app.py drags in FastAPI, so deleting a
line from a text file would have needed a web framework installed.

THREE BUGS FOUND BY TESTING, all in the shell wrapper while the module was
correct throughout -- module-only tests would have caught none of them:

- `[ "$n" -eq 0 ] && echo ...` as the LAST statement made `booth links` exit 1
  whenever the board had rows. `unlink`'s index lookup calls it inside $( )
  under `set -e`, so a successful listing killed the caller and the removal
  silently did nothing while reporting success.
- ids are 8 hex chars and roughly one in forty is ALL DIGITS; those were read
  as row numbers, resolved to nothing, and removed nothing. Now disambiguated
  by the id's actual shape, not by "is it numeric".
- filtering links.md out of the gallery left `items` empty, so a full board
  rendered "This booth is empty" and an empty <div class="gallery"> under 32
  visible rows.

87 tests (was 76): parser tolerance of hand-written prose, content-id
stability across concurrent appends, removal precision, UI branch behaviour
for board/normal/empty booths, and subprocess CLI tests pinning the two shell
bugs. Deployed to nh3-dev and verified against the live 32-row board
read-only; board file byte-identical afterwards.
 2026-08-23 12:55:33 -07:00
vh 4be880f36c feat(booth): kept boards can be deleted from the UI; document the TTL-reset trap 
Kept boards had no delete path in the UI at all. The kept lane deliberately
omits the wipe control -- a one-click wipe next to the durable stuff is a
footgun -- but "deliberate" had been implemented as "impossible": the only
routes out were ssh or a hand-written API call.

Now it is two deliberate acts. A `release` control on kept cards drops the
sentinel, the board moves to the ephemeral lane, and the existing x wipes it
from there. Release is reversible -- POST /b/<name>/keep pins it again.

  POST /b/<name>/unkeep   release the pin
  POST /b/<name>/keep     pin it (round-trip, so release is not a one-way door)

FOUND WHILE TESTING, and it invalidates the previously-documented workaround:
removing the sentinel BUMPS the booth directory's mtime, and booth age is the
newest mtime in the tree -- so a released board's clock RESETS from 10,000s to
0s and it survives another full TTL. The old comment said "remove the sentinel
first (it rejoins the sweep)", which is true but means the board lives another
24h, not that it gets reaped. Unkeep-and-wait is a delay, not a delete.

test_releasing_a_board_RESETS_its_ttl_clock pins that behaviour deliberately so
nobody re-derives the workaround. Release is what unlocks the x; the x is what
deletes.

CLI: `booth rm` already worked on kept boards but said nothing about it. It now
announces "(was KEPT -- durable board)" so wiping something durable can never
look identical to wiping run output. Not a block -- a CLI user naming a booth
is being explicit.

5 new tests (67 pass). Verified live on nh3-dev: release renders on all four
kept boards, the ephemeral lane keeps its x, and the links board is untouched
with its sentinel intact.

vh b8a535507a feat(judge-bench): keep the judge harness; warn about the 7-way alias collision 
Operator: keep the benchmark. It has a named second use (brokkr-smithy-dev
wants gen vs a trained reward model once their tournament converges) and a
demonstrated first one -- it caught a seat that had been coin-flip-grade for
five weeks with nobody measuring it.

Harness promoted from scratch to tools/judge-bench/:
- paths de-hardcoded; runs from its own directory
- proper CLI: --models (REQUIRED), --repeats, --limit, --gateway.
  Required on purpose: a stale default would silently benchmark a retired
  seat, and the original default (selene-1-mini-8b) now 400s.
- README states the limitation rather than burying it: 24 items of the
  author's own design, a screen and not a verdict. This harness scored the
  same pair 83 vs 96 while brokkr's corpus ranking task scored it 47 (chance)
  vs 94. Both honest; absolute scoring on designed items is an easier task
  than ranking real text.
- records brokkr's technique, which is better than anything here: a control
  constructed so the correct answer is DEFINITIONAL rather than judged cannot
  inherit the designer's error (item vs itself, response vs its own
  truncation, text vs its own clauses permuted). Add those before adding more
  judged items.

Gateway: comment-only warning at the head of model_list. SEVEN aliases now
resolve to the same weights (chat-judge, classifier, gen, image-judge,
qwen-image-bench, summarizer, summarizer-large -> qwen3.8-27b-uncensored).
That is intended under ADR-0012, but it has a sharp edge brokkr flagged:
cross-checking a result against another alias measures NOTHING when they are
the same model -- agreement is an echo, not corroboration. The note names the
other current collisions (glm-5.2 x4, TTS x4, reranker x2), gives the
/model/info one-liner to check, and records that probes should resolve alias
-> backing at run start AND end because the response `model` field returns the
alias, so a swap is otherwise invisible.

Verified: config still parses, diff is comment-only, canonical re-synced.
 2026-08-23 05:16:10 -07:00
vh ca3c984f93 feat(selene): retire the seat; chat-judge -> gen, selene-1-mini-8b 404s by design 
Benchmarked selene against gen on selene's own job: 24 designed judge items
with checkable ground truth, pairwise + absolute modes, 3 repeats, on BOTH a
neutral JSON prompt and Selene's native Atla template. 288 calls, all free
local.

  neutral JSON     selene 20/24 (83%)   gen 23/24 (96%)
  native Atla      selene 21/24 (88%)   gen 22/24 (92%)

gen won on both templates and selene's BEST sat below gen's WORST. Selene was
given its own fine-tuned template as a fairness check; it gained one point,
not the three it needed.

Decisive defect: selene cannot emit "tie" -- 0/2 on both templates, forcing a
winner on every equivalent pair. For eval work that is the case that matters
most. gen returned tie correctly on the JSON template. Selene also compressed
the 1-5 scale (clustered at 2s and 4s) where gen used it fully. Selene's only
win was ~3x latency, unexercised at ~60 calls/day with zero queueing.

TWO NAMES, TWO DIFFERENT TREATMENTS, deliberately:

- chat-judge -> repointed to gen. It is a ROLE alias and ADR-0012 says
  consumers bind the capability, not a concrete model. Sampler profile copied
  from image-judge (temp 0, top_p 1.0, top_k 1, thinking off) so the served
  config matches the benchmarked condition.

- selene-1-mini-8b -> REMOVED. It 404s. It was NOT aliased to gen. A
  served-name is a contract about what the model IS; answering it with a
  different model hides a material change behind a stable string. Operator
  ruling: "never repoint a named model at a different model's endpoint --
  that is intentionally misleading." Verified: the gateway now returns
  HTTP 400 "Invalid model name" for it.

Reclaimed 17.2 GiB on ana-ml2 GPU 1 (free 1,818 -> 19,450 MiB) on a card that
had under 2 GiB of headroom. gen already runs on GPU 0, so the judge role
moved onto an existing seat rather than allocating anything new.

Canonical litellm config synced from the host; ana-ml2 README and
recommended-model-settings updated. compose.yaml kept for reference, not
deployed.

vh a896c0a5a9 feat(playbooks): sweep world-readable secret-bearing .env files to 0600 
Eight stacks on ana-docker kept secret-bearing compose .env files at mode
0644 -- readable by every local account on a box with four interactive
users. Verified as a real exposure, not a theoretical one, by reading one
as `nobody`. Six other stacks already used 0600, so this converges on the
existing house pattern rather than inventing one.

Swept (all verified mode 600, unreadable by nobody, compose config still
rendering as the deploy user, container untouched):

  vaultwarden  traefik  beszel  gitea-runner
  miniflux     news-digest  searxng  vor

Post-sweep the host has zero secret-bearing .env readable by nobody.

Checked before writing the playbook, and re-checked by the playbook itself
so a bad case cannot be swept in by accident:
- every target is owned by lkraven, the deploy user, so 0600 preserves the
  deploy path (asserted by rendering compose config AS lkraven, not root --
  checking the mode proves the bits changed, only rendering as the deploy
  user proves the next deploy still resolves its variables)
- none is bind-mounted into a container. vaultwarden looked like it was;
  that `- .env` is under `env_file:`, not `volumes:`. A genuinely
  bind-mounted .env is read by the container UID and 0600 could break it,
  so the playbook refuses that case.

Two gotchas recorded in the file:
- elway's variable regex eats any bare identifier in braces, so a docker
  --format Go template containing {{end}} or {{println}} fails as an
  undefined variable. Grep the raw inspect JSON instead.
- the `ana-docker` ssh alias resolves to lkraven, who needs a sudo
  password; run elway against infra-ops@10.250.50.70 for NOPASSWD.

vh 9642952a54 docs(hrafn-ci): mirror the now-canonical vh/hrafn pipeline; record two failed runs 
claude-bot holds write on vh/hrafn as of 2026-08-23, so the canonical copy of
the pipeline moved there and infra-ops maintains it directly instead of
routing patches through the repo holder. The files here are a verified mirror
(byte-identical to live at 22e0eb9d75a6).

Live state: run 9922 green, and both new content assertions executed rather
than merely existing --

  verify 4/5  host tree matches shipped context (a99ce748a0c9...)
  verify 5/5  image source matches host source (06f209fd0641...)

The CI-computed context hash matching on the host is the end-to-end proof
that the converge lands what CI ships. Its absence is what let the
frozen-source bug survive every green deploy.

Also records why the HEAD == GITHUB_SHA assertion was added and then removed:
it needed the git binary (run 9920, exit 127), and installing git flipped
actions/checkout@v4 from its node implementation to the git binary, which
died on a missing CA bundle (run 9921). A nice-to-have assertion changed the
checkout code path and broke a working pipeline; it guarded a hypothesis that
proved wrong, so it went rather than getting ca-certificates bolted on.
 2026-08-23 02:55:02 -07:00
vh b38c369313 fix(hrafn-ci): staging dir inside the rsync target froze host source silently 
Root cause of nevermore-claude's report that v1.0.0 deployed green while the
host kept serving 0.1.0.

The staging dir was $compose_dir/.stage -- INSIDE the rsync target. So
`rsync -a --delete $compose_dir/.stage/ $compose_dir/` deleted .stage from
the destination (absent from the source listing) DURING the transfer,
destroying the source mid-copy. Reproduced exactly:

  before:  app.py="OLD"  leftover.txt  .stage/app.py="NEW"
  after:   app.py="OLD"  leftover.txt GONE, .stage GONE

Deletion worked; the copy silently did not. So the directory looked
converged while host source stayed frozen at the first manual rsync, and
because the build's COPY inputs never changed, Docker full-cache-hit and
every SHA tag aliased one image. The provenance guarantee was false.

Nothing caught it because the verify steps asserted the marker, health, and
a 200 from /readyz -- all of which pass on a frozen host. None measured
content.

Fixes:
- stage at /tmp/hrafn-deploy-stage, outside the target
- CI computes context_sha256 over the shipped file list; the playbook
  recomputes it on the host post-converge and fails on mismatch
- compare the running container's src/**/*.py against the host's, catching
  a SHA tag naming layers the image does not contain
- checkout clean:true + assert HEAD == GITHUB_SHA so a reused runner
  workspace fails the job rather than shipping a stale tree

Declined --no-cache: a cache hit is correct when the context is genuinely
unchanged, and the new assertions prove the property directly rather than
brute-forcing it.

The container-vs-host check compares only *.py -- `pip install .` generates
src/hrafn.egg-info/* inside the image and __pycache__ appears at runtime, so
a naive `find src -type f` compare false-fails on every healthy deploy.
Verified against the live container before shipping (12 host files, 18 in
container, 0 content differences).
 2026-08-22 21:57:16 -07:00
vh bb19a96f39 fix(playbooks): compare image IDs, not the created-from tag; make the repin idempotent 
Two defects the worldtree-pinned case exposed in the guard written an hour
ago.

1. The guard compared the container's .Config.Image STRING against the tag
   being pinned. That string is only the tag the container was CREATED from,
   which can differ from what it actually runs: worldtree-pinned was created
   from `:latest` back when that tag pointed at 446e5807, and `:latest` has
   since moved to b19afd71d7cc. So the guard refused an instance whose
   pinning was correct and necessary. Now it resolves the target tag to an
   image ID and compares that against the running image ID -- asserting the
   thing actually cared about, that this tag names the bytes now running.
   It also fails closed when no such local tag exists.

2. The sed step reported CHANGED unconditionally, so a re-run on an
   already-pinned instance claimed work it had not done. Gated behind a
   `when:` that skips when the line is already correct; a second run on demo
   now reports "2 ok, 0 changed, 2 skipped / overall: OK".

Applied to worldtree-pinned under worldtree-dev authorization. That instance
needed a `docker tag` first -- its image was DANGLING (no repo tags, kept
alive only by the running container), so the fleet's frozen reference was one
`docker rm` from garbage collection. Tagged as :446e5807bf43, then pinned.

All three instances now render a SHA with no floating tag anywhere:
  worldtree          -> :ae88a057c0ed
  worldtree-personal -> :f63529168c13
  worldtree-pinned   -> :446e5807bf43
Nothing restarted -- pinned still Up 3 months, its start time unchanged.
 2026-08-22 21:52:20 -07:00
vh 064181a8fb feat(playbooks): re-pin Worldtree WORLDTREE_IMAGE off the floating :latest tag 
Both corviduo-dev Worldtree instances carried
`WORLDTREE_IMAGE=.../worldtree:latest` in their .env while running
SHA-tagged images built the same day. The local :latest tag pointed at
b19afd71d7cc, built 2026-06-14 -- 69 days stale. Any `docker compose up`
on either instance, by anyone, silently downgraded that service by 69
days: the same footgun behind the 2026-06-15 outage.

Applied under worldtree-dev authorization (Worldtree #410):
  demo     -> gitea.phasefinal.com/vh/worldtree:ae88a057c0ed
  personal -> gitea.phasefinal.com/vh/worldtree:f63529168c13

Both runs verified compose config resolves every service to the pinned
SHA with no :latest remaining, and that no container restarted. The edit
is inert by design -- it changes what the NEXT recreate pulls.

The playbook guards against pinning a SHA that is not the one actually
running, which would re-arm the same hazard with a different image.

Also records the worldtree-pinned case, deliberately NOT changed here:
that instance runs a DANGLING image (sha256:446e5807, no repo tags),
kept alive only by the running container. It has no tag to pin to, so it
needs `docker tag` first -- and an untagged image referenced only by a
container is one `docker rm` from garbage collection, which for the
fleet's frozen reference instance is worth fixing on its own merits.
Out of the authorized scope (demo + personal); raised with worldtree-dev.

Stopgap: the durable fix is the deploy workflow stamping the deployed SHA
into .env at each deploy, queued repo-side with worldtree-dev.

vh 11b9d1891e fix(hrafn-ci): make the deploy converge instead of accrete 
The first CI run shipped clean but revealed a design gap in the playbook:
unpacking the context tarball in place overwrites tracked files and never
removes anything. Leftovers from the pre-CI hand-rsync (tests/, docs/,
ROADMAP.md, persistent-memory.md, CLAUDE.md, LICENSE) survived the deploy
and had to be cleaned off ana-docker by hand.

That is the same failure class that produced the mess in the first place:
a deploy that only ever adds cannot return the host to a known state.

- unpack to a staging dir, then rsync --delete onto the compose dir
- protect host-owned .env and .deployed by name
- add .env.example to the context tarball so converge does not delete it
- record in the workflow that the tar list is now AUTHORITATIVE: anything
  omitted is removed from the host on the next deploy

Re-validated with `elway --dry-run` (9 steps, 3 verify, parses clean).
Not yet in vh/hrafn -- infra-ops has no write access there, so this is
offered to the repo holder rather than pushed.
 2026-08-22 15:31:50 -07:00
vh b001d0cb2e feat(hrafn): author the CI deploy that replaces the hand-rsync path 
hrafn was handed to infra-ops for uptime ownership with no CI deploy and
no commit provenance -- the image was always local/hrafn:v1 and the whole
working tree lived in the compose directory.

These two files fix both. They are authored here because infra-ops owns
hrafn's uptime, but they belong in vh/hrafn; claude-bot is not a
collaborator there, so they are handed to the repo holder rather than
committed directly.

- playbooks-deploy.yaml -> vh/hrafn playbooks/deploy.yaml
- gitea-workflows-deploy.yaml -> vh/hrafn .gitea/workflows/deploy.yaml

Design calls recorded in the README: the build context travels as one
tarball rather than per-file upload steps (nevermore's pattern fails open
when a new source file has no matching step), and the playbook refuses to
deploy unless .env exists at 0600 -- a guard prompted by it arriving 0644
with a live bearer token in it.

Validated with `elway --dry-run`, which caught a real interpolation bug
during authoring. No new Actions secrets needed.
 2026-08-22 15:26:45 -07:00
vh b6924de728 feat(hrafn): register the browser-fetch service and tighten its env perms 
nevermore-claude handed hrafn to infra-ops for uptime ownership. Intake:
verified health independently, brought it into the inventory, and fixed one
security defect found during the check.

- canonicalize stacks/hrafn/ (compose.yaml + .env.example + README)
- list hrafn in the ana-docker running-stacks table
- README records the load-bearing bits: shm_size 1gb is required for
  Chromium, playwright and the base image are version-coupled, SSRF denies
  private targets by default, and restart:unless-stopped does NOT act on
  healthcheck failure

Security fix applied on the host, not in this tree: /opt/docker/compose/
hrafn/.env was 0644 with a live 57-char bearer token in it, readable by
every local account (verified by reading it as `nobody`). Tightened to 0600;
owner unchanged so the deploy path still works, confirmed via `docker
compose config` as lkraven. Container untouched and still healthy.

Known gaps recorded rather than silently accepted: no CI deploy, and the
image builds from an rsync'd working tree living in the compose directory,
so the running image has no commit provenance.
 2026-08-22 15:05:11 -07:00
vh 7bf17dd39e fix(filezilla): set restart: unless-stopped and canonicalize the stack 
The filezilla container on vm-esh-nas shipped with no restart policy. It
was SIGTERMed during the 2026-08-18 host shutdown and never came back,
staying down four days while dockge/dozzle-agent/beszel-agent all
recovered on their own.

- add `restart: unless-stopped` (applied on the host, container recreated
  and verified serving 200 on :5800 with all four /NAS mounts visible)
- promote the previously un-canonicalized compose into stacks/filezilla/
  so the policy is version-controlled rather than host-only
- record the missing-restart-policy failure mode in the host README

vh 837fa362fc memory: snapshot — sec rebuilt on DFlash2 + newer vLLM; quant tokenizer defect fixed fleet-wide 
Rewrites the in-flight section (140 lines to 18) now that the AI-seat work
has settled, promoting the durable calls into the dated decision log where
they will not decay: DFlash2 measured and promoted to sec's compose stack,
the calibration-truncation defect fixed at source in the quant pipeline,
sec retuned after a runtime OOM, the Max-Q spread disproved by telemetry,
ESH dual-stack with the Cityside static proven unprovisioned, and speaches
live with the weak-gate finding.

Carries forward the two things a fresh session must not get wrong: the sec
degeneration question is confounded because engine and drafter changed
together, and neither the 2k nor the 10k observation is evidence.

Auto-archived one entry (Recent decisions: 1) to archival-memory.md.
Eight further candidates were held back by the guards -- open deferred work
or referenced by in-flight state.
 2026-08-22 09:46:11 -07:00
vh 6e82899ba7 fix(mog-sec): retune to 0.52/420K after a runtime OOM at 0.55/480K 
The 0.55 configuration booted cleanly, passed every startup check, and then
killed the engine on an ordinary request of roughly 20k tokens:
torch.OutOfMemoryError allocating 614 MiB in the GDN causal_conv1d path with
443 MiB free. The container self-recovered via restart: unless-stopped.

Context length was not the cause. gpu-memory-utilization is not a hard
reservation. Weights and KV are reserved up front, but activation memory is
allocated on demand and the profile that sizes it uses dummy data at
max_num_batched_tokens. The profile predicted 3.62 GiB; the process sat about
1 GiB over its entire budget even at idle. With six vLLM containers sharing
GPU1 there was no slack left to grow into, and a modest allocation lost the
race. 0.52 leaves roughly 7.7 GiB free against 4.6 GiB at 0.55.

Records a measurement that governs how max-model-len can be chosen at all:
the KV pool varies between boots. Two consecutive boots at 0.52 produced
425,663 and 453,600 tokens, a 6.6 percent swing, because the pool is sized
from free memory at startup and that depends on what the other tenants hold
at that instant. 420,000 sits under the lower observation so the seat starts
in both conditions. Sizing to the higher one would boot today and refuse
tomorrow, which is why the value was measured across boots rather than
estimated from one.

Concurrency of about 1.0 to 1.08x means one request at full length. Shorter
requests still batch normally, since vLLM schedules by tokens rather than by
max-model-len.
 2026-08-22 02:03:24 -07:00
vh 8389470898 feat(mog-sec): promote the DFlash2 configuration into the compose stack 
Operator approved after real-use testing. The experimental standalone
container is retired and stacks/mog-sec is canonical again, with
restart: unless-stopped so the configuration survives a reboot.

Cutover verified against the container it replaces: KV pool 526,617 tokens
at 1.10x concurrency, identical; zero restarts; both gateway aliases
serving; DFlash2 confirmed drafting at k=7 with 231 draft tokens over 33
drafts; vision working at 2048x2048.

One variable was deliberately dropped rather than carried over. The previous
stack hardcoded PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True, the
validated container never set it, and the quant playbook records
expandable_segments corrupting retained tensors in another context. The
compose now defaults it empty via MOG_ALLOC_CONF. Promoting the stack as it
stood would have shipped a variable the tested configuration did not have.

The speculative config moves into a single MOG_SPEC_CONFIG carrying the
whole JSON, because the two shapes are not interchangeable: dflash requires
a model pointing at the drafter and MTP must not have one, so a
method-plus-tokens template cannot express both. Also parameterised:
MOG_DRAFT_MODEL, MOG_MM_PROCESSOR_KWARGS, MOG_MAX_NUM_BATCHED_TOKENS.

The mm-processor image cap is now mandatory rather than incidental. The
model's own preprocessor declares 4096x4096, which expands to 16384 image
tokens and kills startup on builds that enforce the image-token count check.

Adds the .env.example this stack never had, carrying the measured rationale
for each value and the one-line rollback.
 2026-08-22 01:16:27 -07:00
vh 20ac53052b memory: retract the MTP-head degeneration hypothesis; n=1 was never evidence 
Operator ruling: the multi-turn degeneration lives in the un-fixed vLLM, not
in the weights. The hypothesis that sec's stock-graft MTP head causes it is
withdrawn.

Two failures produced it. First, a false dichotomy treated as a deduction:
having verified gen and sec run an identical engine, I concluded config was
eliminated and therefore the weights were responsible. That does not follow.
An engine bug present in both seats is not exonerated by the seats being
identical; it only means the engine cannot explain a difference between
them. It can still explain the failure.

Second, and more instructive, the difference being explained may not exist.
The premise was a single operator observation made during a session with
many concurrent changes. That cannot carry a causal claim, and it became the
load-bearing support for a root-cause narrative it could not hold.

The same caveat now attaches to the coherent-to-10k observation on the new
build: same n, same uncontrolled conditions, opposite direction. The
comparison is weak at both ends, so the file no longer presents either
sighting as a result.

What survives as measured fact is unchanged and still recorded: sec's MTP
head is byte-identical to the uncensored base across all 15 tensors, gen's
was abliterated in-band, and acceptance differs slightly. None of that is
shown to cause degeneration.

Adds the generalisable lesson: an observation made while many things are
changing cannot support a causal conclusion. It is the inverse of the
warning already in the gen-seat compose file, which guards against trusting
a negative result from a synthetic probe; this guards against trusting a
positive sighting from an uncontrolled session.
 2026-08-22 00:58:35 -07:00
vh ab3a0ca5bc docs(quant-playbook): acceptance is not throughput -- always run the depth control 
Measured 2026-08-22 on one target with one instrument: raising MTP
num_speculative_tokens from 3 to 7 improved accepted length from 2.753 to
3.041 per forward pass while throughput fell from 114.9 to 74.0 tok/s.
Reporting acceptance alone would have recommended a 36% regression.

The cause is architectural rather than model-specific. A single-module MTP
head has no depth of its own, so vLLM runs it autoregressively and k draft
tokens cost k sequential forward passes. Past a shallow depth the drafting
cost exceeds what the extra accepted tokens save.

Records the comparison rule that follows: match k when comparing two
speculative methods, or the measurement is of depth rather than method. A
parallel-drafting drafter at k=7 against an autoregressive MTP at k=3 is not
a method comparison. In the case that produced this, the depth control
showed most of the apparent acceptance advantage was depth, while the
throughput advantage was real and came from parallel drafting -- our MTP was
better at position 0 and still lost overall.

Only the measured, model-agnostic result is recorded here. The
DFlash2-specific findings, the hypotheses that remain unproven, and the
wrong turns taken along the way live in
persistent-memory.d/2026-08-22-dflash2-spec-decode.md with explicit
epistemic labels, deliberately kept out of the playbook.
 2026-08-22 00:52:06 -07:00
vh 9f87b7c4e5 memory: DFlash2 spec-decode measured; sec running on it (experimental, confounded) 
Records the 2026-08-22 session with measured results, hypotheses, and wrong
turns explicitly separated -- the operator held this back while it was in
flight specifically so conjecture would not enter the record as fact.

MEASURED. DFlash2 works on an abliterated + NVFP4 compressed-tensors target
on Blackwell sm_120, which the model card does not claim (it tests stock
BF16 on H200). gen 2.753 -> 3.254 accepted tok/forward and 114.9 -> 131.9
tok/s; sec 2.676 -> 3.252 and 110.5 -> 130.0. The drafter is model-agnostic
across two different finetunes to 0.06%, but is EAGLE3-style coupled to its
target's hidden states, so the weights file is shareable while the 3.85 GB
of VRAM is per-seat.

The k=7 MTP control is the load-bearing result: raising MTP depth improves
acceptance and collapses throughput to 74.0 tok/s, because a single-module
head run autoregressively costs one forward pass per draft token. Without
that control the obvious recommendation would have been wrong.

CONFOUNDED. sec no longer degenerates at 2k, but the engine advanced 259
commits and the drafter changed at the same time. Isolating it means running
MTP k=3 on the new build. Also recorded: #51113 is present in both builds
and is therefore necessary but insufficient, since sec ran it and still
degenerated.

HYPOTHESES, labelled as such: that sec's stock-graft MTP head causes the
degeneration, and that NVFP4 explains the gap against published acceptance
figures. Neither is proven.

WRONG TURNS, recorded so they are not re-derived: version strings are not
lineage, Docker Hub push timestamps are not source freshness, and the claim
that 1M context needs YaRN absent from config is false for the sec quant.

Operationally important: sec is serving from a standalone container rather
than its compose stack, which is stopped but unmodified. Rollback is two
commands and is written down.
 2026-08-22 00:51:28 -07:00
vh 0755ba7d00 fix(quant): stop baking the calibration truncation cap into the shipped tokenizer 
load_calib tokenizes with tok(..., truncation=True, max_length=seqlen). For a
fast tokenizer that mutates the Rust backend's truncation state in place, and
the subsequent tok.save_pretrained() persisted it, so every mixed-NVFP4 build
shipped a tokenizer.json carrying

  "truncation": {"direction": "Right", "max_length": 2048, ...}

against a source whose value is null. Every prompt was clamped at the
calibration length, permanently.

It hid because older transformers does not enforce the text-vs-ids count
check. On a newer one the seat dies at startup with a message that names
images and never mentions tokenizers:

  ValueError: Mismatch in `image` token count between text and `input_ids`.
  Got ids=[2047] and text=[16384].

The cap also silently limited image resolution well before it killed
anything -- at 2048 the largest servable image is about 1448x1448, since
(edge/patch)^2 / merge^2 image tokens have to fit under it.

Fix saves a pristine tokenizer re-read from the source rather than the
mutated calibration object, and then asserts truncation is null so the
defect fails the build instead of shipping again.

Playbook gains section 3.14 with the symptom, the cause, the audit one-liner
and a table of which builds were affected, plus a fourth mandatory post-step.
The transferable lesson is called out: this is the third case of an artifact
carrying config authored against an older transformers that a newer one
begins enforcing, so an image bump is a config-compatibility event rather
than just a version change.

vh ad21302474 memory: ESH internal IPv6 live on two LANs; Cityside v4 static proven unprovisioned 
Operator-directed IPv6 enablement on ESH-UDMPM: esh-userland (VLAN 10, SSID
PVC) and esh-server flipped from ipv6_interface_type=none to pd against the
delegated 2607:73c0:402:1d00::/56. Verified esh-docker-vm egresses over v6 as
its own address with no NAT, against v4 which still egresses as the shared
CGNAT pool. No disruption through either write; originals backed up.

NH3 stays v6-off deliberately -- its single /64 is reserved for network
meshing, so nh3-dev having no v6 egress is correct rather than a fault.

The v4 static is NOT provisioned, and this is now proven rather than
inferred. A full gateway reboot -- verified by observed down-transition and
an uptime reset from 140,846s to 183s -- forced a fresh DHCP DISCOVER and
Cityside returned the identical address. Recorded alongside it: a DHCP renew
could never have surfaced a new address in the first place, since renewal
preserves the lease by design. Next step is a carrier ticket, not more
testing.

The v6 firewall posture was audited and is correct -- default-deny inbound
for both IP versions, only four hand-written policies, none WAN-facing. My
earlier warning that v6 removes CGNAT's accidental shielding was overstated
and is retracted in the record. The audit's limitation is stated: it read
rules, it never probed from outside, because no v6 vantage exists.

Flat-zone lateral-movement finding parked as id 44 rather than actioned --
operator's call, moot until the mesh and segmentation design settle.

vh c7e21879ae memory: speaches ASR live on irv-ml1 — and no_speech_prob is a weak gate 
Records the deployment plus the finding that outlives it: no_speech_prob
alone does not carry a hallucination threshold on this stack. Silence and
room tone both hallucinated 'Thank you.' at no_speech_prob under 0.11,
where a conventional >0.6 gate passes them through; avg_logprob separates
~6x better. Any future consumer asking for a Whisper hallucination gate
should be pointed at the composite, not the single field.

Also banks the digest-pin rationale (the VAD flag is an upstream-declared
unstable variable name, so a floating tag can move gate semantics
silently), the two deployment gotchas, the docker-vs-native GPU index
inversion on this host, and Eyra's future diarization VRAM claim on the
same A6000.

Adds speaches to the irv-ml1 stack table alongside parakeet, with the
reason both exist.

vh aa5863c9a3 feat(speaches): OpenAI-compatible faster-whisper ASR seat on irv-ml1 A6000 
Deployed for Eyra (meeting recorder) per the eyra-dev request. Serves
large-v3 (batch tier) + distil-large-v3 (low-latency tier) on :8204,
fp16, both resident, ~5.9 GB VRAM against 20 GB still free.

Sits alongside the existing parakeet stack (:8765) deliberately: parakeet
is a TDT/transducer returning bare {"text": ...} and has no no_speech_prob
concept, so it structurally cannot serve this consumer.

The load-bearing requirement -- segments[].no_speech_prob surviving
response_format=verbose_json -- is VERIFIED on both tiers.

Measured finding worth more than the deployment: no_speech_prob alone is a
WEAK hallucination gate on this stack. Pure silence and pink room tone both
produced the classic Whisper 'Thank you.' hallucination while no_speech_prob
stayed under 0.11 -- a conventional >0.6 threshold passes both through.
avg_logprob separates the same cases ~6x more decisively (-0.11 speech vs
-0.65/-0.72 non-speech) and compression_ratio splits 1.141 vs 0.556.
Consumers should gate on a composite, not no_speech_prob alone. Table in
the README.

VAD pinned OFF at the consumer's request (they VAD-gate upstream on the
capture edge). Consequence stated plainly in the README: with VAD off this
service will transcribe silence into text and is not defending itself.

Image pinned BY DIGEST rather than :latest-cuda, because the VAD-off
setting rides on _UNSTABLE_VAD_FILTER -- a variable upstream explicitly
marks unstable. A floating tag could rename it on any bump, silently
restoring VAD and moving no_speech_prob semantics under a calibrated gate
with no error and no log line.

Two deployment gotchas recorded: PRELOAD_MODELS only loads models already
cached (it does not download -- use POST /v1/models/{id}), and the bind-
mounted cache needs a hub/ subdir or every /v1/models call 500s with
CacheNotFound while /health still returns 200.

vh ff5ce212da memory: OWUI credential state — password reset, admin-scoped API key vaulted (operator-ruled) 
Two OWUI credential facts worth surviving a context reset:

  - The reported lockout was NOT a broken account. The vaulted password returned
    200 from POST /api/v1/auths/signin immediately before the reset, so the cause
    was client-side. Test the vaulted credential against signin before concluding
    an account is broken -- this is the second lockout here traced to an assumed
    rather than verified credential.
  - The operator-minted API key is ADMIN-scoped, inherited from the owning user,
    and that is the INTENDED shape per operator ruling: infra-ops manages the
    instance, so the key needs the rights the management work requires. A
    least-privilege dedicated-user split was offered and declined. Do not
    re-propose it.

Both credentials vaulted at esh-docker-vm/open-webui-{admin,api-key}; key verified
against /api/v1/auths/ (admin identity) and /api/models (33 models), with an
unauthenticated 401 control. Plaintext copies shredded.

Also folds in an unadjudicated drift found in passing: the running image is the
floating ghcr.io/open-webui/open-webui:main, not the v0.11.0 the stack notes
claim. Replaces the now-resolved 'operator's OWUI password change' follow-up.

vh 5e47a59b32 feat(meromero): MeroMero-v2 dual-mode (prose + streaming CoT) live on one seat — no re-quant 
The multi-turn Gemma-4 CoT problem is solved. One MeroMero-v2 seat, one weight set,
two aliases: char-rp (prose) + char-rp-reasoning (streaming chain-of-thought).

The winning stack, traced from vLLM source by the four-arm brokkr/dwarf panel:

  - vllm/vllm-openai:v0.26.0 — ships transformers 5.14.1 natively, below the
    head_dim guard, so Gemma-4-31B loads with no pin and no custom image. It also
    carries the #48217 streaming pre-arm fix.
  - A patched chat template whose enable_thinking:true branch force-opens a BARE
    <|channel> (not <|channel>thought\n -- full-open defeats _preprocess_feed's
    injection). --chat-template override, no re-quant.
  - Two served-names char-rp / char-rp-thinking; --reasoning-parser gemma4;
    default enable_thinking:false. LiteLLM char-rp -> prose, char-rp-reasoning ->
    the thinking served-name with enable_thinking:true.

Verified: streaming CoT split 6/6 direct on :8016 and 3/3 through the gateway;
char-rp prose clean on both transports with no trailing-token leak.

Two hard-won facts recorded in persistent-memory:
  - STREAMING ONLY. Non-streaming can't split -- extract_reasoning never receives
    prompt_token_ids so the pre-arm can't fire (a vLLM one-shot bug unchanged
    across v0.24-0.27). Fine here: Lobe/OWUI stream. Upstream PR #49797 fixes
    non-streaming too, landing ~v0.28.0 -- then it's a clean image bump.
  - KEY-NAME TRAP: vLLM streams reasoning in delta.reasoning; LiteLLM normalizes
    to delta.reasoning_content. I lost two false-negative test rounds to this.

Canonical: stacks/meromero-charrp/ (compose + patched_chat_template.jinja) and
stacks/litellm/conf/config.yaml. Rollback is the .env image line + dropping
--chat-template.

vh 76834777a4 feat(open-webui): deploy env-declarative chat bake-off on esh-docker-vm:3211 
Stand up Open WebUI v0.11.0 parallel to lobe-chat (:3210) as an
operator-approved candidate replacement. Env-declarative config
(ENABLE_PERSISTENT_CONFIG=False = the deploy is the config source of
truth), model picker auto-tracks the LiteLLM gateway with no pins,
background task model pinned to summarizer, TTS routed direct at the
dots gateway (:8198).

Gates verified on the box: G1 (declarative config, both directions),
G2 (picker == live gateway roster, no hand-listing), G3 (models/sync
genuinely reconciles create+delete), G5 (task model pinned). G4 (TTS)
handed to tts-dev.

Credential posture (G6): fresh capped LiteLLM key open-webui-esh
(all-proxy-models, $50/1mo budget) rather than inheriting the uncapped
lobe-chat-esh key; signup locked off after admin creation. Secrets
vaulted under esh-docker-vm/open-webui-*.

Note: the API-key toggle env var is ENABLE_API_KEYS (plural); a var
only reaches the container if compose names it in environment:.
lobe-chat is untouched.

vh f01ee28cea memory: gemma4 CoT test on v0.27.1 blocked by config incompatibility (reverted) 
Tried serving the MeroMero NVFP4A16 quant on vllm/vllm-openai:v0.27.1 to test the
per-request enable_thinking hypothesis. Couldn't even load it:

  - v0.27.1's stricter transformers raised AmbiguousGlobalPerLayerAttributeError
    on the Gemma-4 config's head_dim (now a per-layer attribute).
  - Setting allow_global_per_layer_attribute_access on text_config downgraded that
    to a warning, but then gemma4.py load_weights asserted:
    "Attempted to load weight (512) into parameter (256)". Gemma-4-31B is
    genuinely heterogeneous -- some layers have head_dim 512, not a uniform 256 --
    so forcing the global value built wrong-shaped parameters. The guard was right.

So the MeroMero quant's config was authored for v0.24.0's Gemma4 loader and cannot
load on v0.27.x without a config migration or a re-quant against newer transformers.
The per-request-kwargs hypothesis was never reachable -- the model wouldn't load.

Consequence worth carrying: the eventual gen-seat move to v0.27.2 stable must
re-verify config-compat for any Gemma-4 seat of this vintage.

Fully reverted: config.json restored (flags removed), image back to latest
(v0.24.0), gateway char-rp-reasoning removed, char-rp prose verified. char-rp stays
on v0.24.0; MeroMero CoT remains undelivered. For RP-with-CoT use gen-reasoning, or
re-quant MeroMero against v0.27.x (real work, unproven payoff).

vh 7ebbcec5bb memory: vLLM release status for #51113 — no stable yet; gemma4 CoT is decoupled 
Checked upstream. Latest stable is v0.27.1 (Aug 11) and it does NOT contain
#51113 -- the v0.27.0..v0.27.1 compare is only "DSpark Markov heads" plus three
CI commits. The #51113 cherry-pick (khluu, Aug 9, "v0.27.0 cherry picks"
milestone) is staged on the release-0.27 branch but no v0.27.2 stable has been
cut; only v0.27.2rc1 / the pinned nightly carries the fix. So the standing
follow-up (move gen off the nightly) still waits on a v0.27.2 stable cut.

Key decoupling: #51113 fixes the Qwen3.8 MTP + prefix-caching accuracy drop
(#43559). It is irrelevant to Gemma-4 seats, which have no MTP head. So the
meromero/gemma4 CoT test does NOT need the nightly and does NOT need #51113 -- it
can run on the latest stable v0.27.1, which is newer than the seat's current
v0.24.0 and where per-request chat_template_kwargs is expected to work.
 2026-08-21 08:37:06 -07:00
vh b84ad888d6 memory: CORRECT the MeroMero-CoT finding — not a hard wall, not MeroMero-specific 
My prior entry claimed the gemma4 reasoning parser is process-wide and the CoT
was architecturally blocked. Reading the actual code proves that wrong:

  - Template (chat_template.jinja:347-352): thinking is a PER-REQUEST toggle.
    enable_thinking:false prefills an empty <|channel>thought<channel|> to
    suppress; true omits the prefill so the model can emit a real thought channel.
  - Parser (vllm/reasoning/gemma4_utils.py): splits on <|channel>/<channel|> tag
    presence, "works with or without enable_thinking" -- NOT a process-wide flag.
    The stale compose comment I trusted cited an old parser API (vllm/parser/
    gemma4.py:439) this container doesn't run.

So the mechanism is gemma4-GENERAL (any gemma4 finetune on this template family),
and the two-served-name gen pattern should work. What actually failed the test was
that meromero runs vllm/vllm-openai:latest (v0.24.0), where per-request
chat_template_kwargs.enable_thinking didn't take effect -- whereas the gen seat's
pinned nightly demonstrably applies it. That's a version/plumbing issue, not the
model and not the architecture, and it would hit any gemma4 finetune on that image.

Unverified fix (needs a GPU window): re-serve meromero on the nightly image with no
process default and per-request enable_thinking. Currently reverted to known-good.
 2026-08-21 08:25:02 -07:00
vh a260b57974 memory: MeroMero-v2 CoT via vLLM gemma4 parser is not achievable (tried + reverted) 
Operator asked to serve MeroMero (char-rp) with reasoning as char-rp-reasoning.
The model genuinely reasons (GRPO-trained with thinking; ships Think/NoThink
SillyTavern presets), but two facts kill the vLLM path:

  - it's byte-identical to the weights we already serve (same zerofata repo,
    chat_template sha 94899c0f matches our on-disk quant), so re-quanting adds
    nothing; and
  - the gemma4 reasoning parser's enable_thinking is PROCESS-WIDE, not per-request.
    The seat's --default-chat-template-kwargs sets the parser state machine; a
    per-request chat_template_kwargs.enable_thinking reaches the template but not
    the parser (unlike the qwen3 parser the gen seat uses). So the two-served-name
    gen/gen-reasoning trick can't work.

Verified empirically: added a char-rp-thinking served-name and removed the process
default; enable_thinking:true per request still produced pure prose, 0
reasoning_content. Per the seat's own comment, a dedicated thinking-on process
dumps all prose into reasoning_content with null content -- no clean split.
MeroMero reasons only client-side in SillyTavern, not through vLLM.

Fully reverted to known-good: single served-name, process default restored,
char-rp prose verified end-to-end. GPU0 both seats healthy, gen untouched.

Kept one change: MEROMERO_GPU_MEM_UTIL 0.52 -> 0.51. 0.52 no longer boots because
orcarouter gen (the GPU0 neighbor) is marginally bigger than the old heresy seat
(free 49.02 < needed 49.38 GiB); 0.51 fits at KV 2.00x @ 262K.

For real RP-with-CoT: gen-reasoning (orcarouter, uncensored, thinks) or a dedicated
Qwen-based RP-thinking seat, which needs a GPU slot.

vh 3d30a6530b feat(lobe-chat): pass every chat-capable model through the picker 
Operator: "pass everything through, lobe is a test surface for me." The picker
goes from 11 curated seats to all 25 chat-capable models the gateway serves,
paid passthroughs included.

Membership is derived from LiteLLM's declared `mode` rather than by taste:
chat (15) and completion (1) are in, and the nine GLM/frontier entries whose
mode is unset are chat models in practice. Out: audio_speech (ext-tts, tts-1,
tts-1-hd, gpt-4o-mini-tts), embedding (qwen3-embedding) and rerank (reranker,
reranker-a3-bge-v2-m3) — seven models that cannot answer a chat request at all,
so listing them would recreate the visible-but-dead entry this list just got
fixed for.

Every candidate was probed live from inside the container before being pinned,
which corrected an earlier claim in this file. char-rp and char-rp-reasoning
are NOT retired: they are configured and their upstream seat (ana-ml2:8016) is
refusing connections while under maintenance, which is a 500, not a 400. Both
are retained deliberately — dropping a name because its seat is bouncing makes
the list rot in the other direction. Only char-rp-fable is genuinely gone (400,
absent from model_info). The comment now spells out the 400-vs-500 distinction
so the next editor does not repeat the mistake.

Also corrects the credential-posture header, which still described the key as
scoped to free local models and cited the glm/kimi rejection as current
verification. The key now carries the all-proxy-models access group with no
budget ceiling, so that block had become a false security claim in the most
load-bearing comment in the file.
 2026-08-21 08:11:17 -07:00
vh 303fb7a5aa feat(lobe-chat): add the sec seats to the picker, drop two retired ones 
Two independent gates kept the new `sec` family out of Lobe, and only one of
them was visible from the symptom.

The picker never auto-discovers. `OPENAI_MODEL_LIST=-all,+<names>` clears
Lobe's built-in OpenAI catalogue and re-adds one model per `+name`, so anything
added to LiteLLM stays invisible until this list is edited and the container
bounced. That pin is deliberate — an unpinned picker offers models that fail on
click — but it means the list rots in both directions, and it had:

- `sec` / `sec-reasoning` missing (hosted_vllm/mog-sec-27b{,-thinking} on
  ana-ml2:8019, added to config.yaml earlier today), and
- `char-rp-reasoning` / `char-rp-fable` still listed after being retired
  upstream, i.e. two picker entries that 400 on click. Verified: a call to
  char-rp-fable now returns 400 Bad Request.

The list is now curated to live, chat-capable, free-local seats — eleven, each
round-tripped through the container after the bounce. The paid family stays out
deliberately; that is now a picker decision rather than a key one.

Which is the other half of this commit: the `lobe-chat-esh` key is no longer
scoped to free local models. On the operator's instruction infra-ops swapped its
explicit array for the `all-proxy-models` access group, so it now reaches the
paid passthroughs with `max_budget: None`. The README documented the old posture
as current, which made it a security claim that was no longer true; it now
carries the change, what it costs, and the fact that the picker is the only
remaining gate.

Operator's call: the pen-test seat is reached as `sec` (non-thinking) and
`sec-reasoning` (thinking). Backend and served-model-names (mog-sec-27b[-thinking]

vh 36c173c6a1 feat(mog-sec): quant + serve M.O.G.-SEC pen-test seat; PPL on gen; retire fable 
Autonomous overnight run under the operator's full-autonomy grant. End state:
fleet up, gen seat untouched, a new verified pen-test seat serving where fable was.

PPL on the orcarouter gen seat (fable downed to free GPU1 for a nospec probe,
probe torn down after): mean 7.07 / median 5.76, within noise of heresy 6.910 /
5.625 and identical to our recipe's usual 7.059. The gen-seat search is settled.

M.O.G.-SEC: chose Blackfrost-Research/M.O.G.-SEC-27B-1M-CTX-BF16 (rev deede677)
over the pre-made ModelOpt NVFP4, which was disqualified on W4A4 4-bit activations
(the AEON degradation mode, catastrophic on a 1M-context model), zero MTP tensors,
and ModelOpt format. Pulled, format-screened (P(<think>) 1.11e-05, clean), quanted
in-house to mixed NVFP4+FP8 (23.4 GB, MTP + vision preserved), and served in the
retired fable slot.

  stacks/mog-sec        ana-ml2 GPU1 :8019, KV 418,218 tok / 1.60x @ 262K
  aliases               mog-sec (non-thinking), mog-sec-reasoning (thinking)
  gates                 surface 6/6, MTP 55.3%, format 0/15 leak, vision 7/3/1,
                        capability 4/4 (delivers offensive-security content)

Served at native 262K, NOT the card's 1M -- the 1M needs YaRN (absent from the
weights' config) plus the SGLang/DFlash2 path the repo ships a deployment kit for,
neither of which is our vLLM surface. A real 1M seat is a separate SGLang project.

Retired char-rp-reasoning + char-rp-fable (zero traffic, pointed at the downed
fable :8019; now 404 cleanly, not repointed -- a security model is not an RP model).
char-rp (meromero) untouched. Vision preprocessor built from the model's own
image_processor block, same trick as the MeroMero seat.

GPU0 seats (gen, meromero) were untouched and healthy throughout. The quant ran in
GPU1 free space with no production seat stopped except fable, which was replaced.

vh e4576f0989 test(gen-seat): PPL on orcarouter — mean 7.07 / median 5.76, within noise of heresy 
Measured against a spec-decode-free probe on GPU1 (fable downed to free the VRAM,
probe torn down after). eval_quality.py aborts PPL under --speculative-config, so
a nospec probe is the only way to read it.

  orcarouter  mean 7.0655  median 5.758
  heresy      mean 6.910   median 5.625   (+2.2% mean)
  our recipe's usual mixed-quant PPL: 7.059 -- orcarouter is identical to it

So orcarouter matches heresy on fidelity and wins on every other axis: MTP
acceptance 58.4% vs 47.2%, zero think-leak, vision 7/8. The gen-seat search that
ran through Cold-Fusion, heresy, and preetpatel is settled on orcarouter.
 2026-08-21 02:06:52 -07:00
vh ce09ac4fa6 test(gen-seat): add a real vision battery — orcarouter scores 7/8 
surface_test.py's vision check is one image and one word. It proves the tower
loads; it does not prove the tower works. This battery uses generated images with
known ground truth so every answer is objectively gradeable.

Against orcarouter NVFP4-mixed on the `gen` alias:

  T1  OCR, 5 lines incl. one at 18px          PASS  all 5 exact
  T2  counting + attribute binding            PASS  7 circles / 3 triangles / 1 square
  T3  bar chart, 6 values + max/min           PASS  6/6 exact
  T4b occlusion, star behind rectangle        PASS
  T4c aspect ratio of a 160x140 rectangle     FAIL  called it taller than wide
  T5  two images, which has text              PASS
  T6  four images, the seat's cap             PASS  all four named
  T7  five images, one over the cap           PASS  rejected with HTTP 400

No <think> leak on any vision call.

The single miss is fine-grained relative-dimension estimation on a near-square
shape, and it reproduced across two runs (the longer T4 called the same rectangle
"equal width and height"). Counting, OCR, chart values and occlusion ordering are
all solid, so this is a precise-geometry weakness, not a broken tower. Recorded so
nobody builds a feature on this model judging relative sizes.

T7 earns its place separately: it confirms the per-prompt image cap fails loudly
with a 400 rather than silently dropping the extra image.

For scale on the leak gate, the abandoned h300 build scored 8/30 on this exact
instrument, and its abliteration-survival samples had 2 of 4 open with
"<think>Ok, let's figure this out:". Orcarouter has none.

The headline is MTP acceptance. 58.4% against heresy's byte-identical base head
at 47.2% is +11 points, and it sits level with our own in-band L35 at 59.1%. That
is the additive in-band-vs-graft delta the entire Cold-Fusion experiment was built
to measure and never cleanly delivered -- orcarouter handed it over for free
because the author had already done the Robinson edit on the head.

Surface 6/6 covers plain chat, vision, tool calling, the thinking split, a
36,042-token long-context retrieval, and streaming.

PPL remains blocked on a spec-decode-free probe seat: it needs ~22 GB and GPU1 has
~16 GB free. Comparison target is heresy at 6.910.

Operator directive was seat-first so he can test while the gates run.

GEN_MODEL -> /tank/aimodels/qwen38-27b-orcarouter-nvfp4-mixed. Healthy in ~4 min.
KV pool 401,550 tok / 1.53x. MTP drafter detected and wired, sharing embedding and
lm_head with the target. 7/7 gateway aliases 200. Vision correct on the shape
probe. Live decode observed at 102-133 tok/s under load.

Critically, <think> does not appear in the top-20 first tokens on the live seat.
That is the Cold-Fusion failure mode measured absent in production, matching the
pre-quant screen on the bf16 (1.23e-06, rank 52).

Rollback is one line to .env.bak-heresy-restored-20260821.

Full gates were still running when this landed; PPL stays blocked on a
spec-decode-free probe seat, which needs ~22 GB against GPU1's ~16 GB free.

vh c8f128bdff feat(gen-seat): quant orcarouter — its MTP head is already Robinson-abliterated in-band 
Pulled orcarouter/Qwen3.8-27B-Uncensored at rev 9878936b (55.5 GB, gated, our
token has access) and built /tank/aimodels/qwen38-27b-orcarouter-nvfp4-mixed
(23.4 GB, mixed NVFP4+FP8). Verified, not yet cut over.

The operator asked whether we could apply the Robinson path to the MTP head. We
cannot, because the author already did. compare_mtp_head.py against the verbatim
base graft: 13 of 15 tensors byte-identical, exactly 2 differ --
mtp.layers.0.self_attn.o_proj.weight and mtp.layers.0.mlp.down_proj.weight, which
are precisely the two residual writers our own abliterate.py targets
(EXPECT_MTP_WRITERS = 2).

Reverse-engineered the edit from the weights alone (mtp_delta.py, added here):

  sigma2/sigma1 = 0.0164 on BOTH tensors    rank-1, a single-direction projection
  |cos| between the two recovered dirs = 1.0000   ONE shared direction
  ||delta||/||W|| = 1.42% and 1.41%         a gentle, consistent projection
  sink energy dim 3994 = 0.0000%            sink-clean; Heretic's was 6.18%

That is the Robinson in-band MTP abliteration, already applied, with a direction
that passes our sink screen outright. Nothing to do but preserve it, and the quant
carries it byte-identically. This is the configuration the entire Cold-Fusion
experiment was designed to test and never cleanly delivered.

The new format screen paid for itself on its first real use: think_prior.py on the
bf16 BEFORE any GPU time gave P(<think>) = 1.23e-06 at rank 52, against
Cold-Fusion stock 0.1850 and h300 0.2216. Roughly 150,000x cleaner.

Two durable findings about the pipeline itself:

The quant needs ~17 GB, not a whole card. It ran entirely in GPU1's spare 16 GB
with ZERO production seats stopped -- the h300 run's "stop BOTH GPU0 seats" was
never necessary, it simply had a free card by coincidence. The first attempt OOM'd
by 2.37 GiB at layer 64 of 65 with 3.57 GiB reserved-but-unallocated, which is
fragmentation, and PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True closed it.

post_quant.py now builds a missing output index from the safetensors headers.
A sub-23 GB quant saves one bare shard with no index, and post_quant needs one;
this has broken three separate rounds and been hand-fixed every time. The header
is read by struct-unpacking the u64 length and parsing the JSON -- never
safe_open, which mmaps the whole 22 GB shard and ENOMEMs on ZFS.

Artifact verified: mixed-precision, 1968 tensors, 15 mtp, 333 visual, re:^mtp.*
present in the ignore list (llm-compressor pruned it as always), preproc restored.
Imatrix deferred per operator; the log confirms the usual uniform-MSE fallback, so
this build stays apples-to-apples with heresy's PPL 6.910.

vh bf65d0254d docs(pfi): evaluate the two gen-seat replacement candidates 
preetpatel/Qwen3.8-27B-Uncensored-NVFP4 is disqualified on two independent hard
failures, both read directly off the artifacts via HTTP Range requests against the
safetensors header (about a megabyte, not a 20 GB download):

  - ZERO mtp tensors. The author's recipe.yaml asks to ignore re:.*mtp.*, but the
    written config.json has no mtp ignore entry while re:.*visual.* expanded to 110
    explicit ones. That asymmetry is llm-compressor pruning a pattern that matched
    nothing, i.e. the MTP head was never loaded. Costs roughly half our decode.
  - NVFP4 W4A4, 4-bit activations. Precisely the AEON failure mode: the fidelity
    gradient is W4A4 < W4+FP8 < W4+bf16, W4A4 drove ~15-20% stochastic degeneration,
    and it collapses past ~30k context. The gen seat serves 262K.

orcarouter/Qwen3.8-27B-Uncensored checks out as a quant source: stock-Qwen base
rather than a reasoning-compression finetune, Arditi-style single-direction
abliteration, 15 mtp and 333 visual tensors verified present, chat template
byte-identical to the heresy build we are serving, and the gate is already accepted
on our token.

Also records the author's FP8 release as a noted-but-not-recommended third option:
far more traction, but 30.9 GB against NVFP4's 22 GB, and on a zero-sum GPU0 that
+9 GB comes out of the KV pool and breaks 262K context.

And states the imatrix constraint plainly. Our recipe has always requested
imatrix_mse and always silently fallen back to uniform MSE; playbook 3.13 warns
against assuming an imatrix would help before verifying llm-compressor can consume
external importance data at all. The W4A16 portions are data-free by construction
and cannot use it regardless.

vh 48410a6a90 chore(coldfusion-abliteration): delete the Cold-Fusion bf16 weights — ~154 GB reclaimed 
Operator directive following the decision to abandon the Cold-Fusion base.
Removed with explicit literal paths, one at a time:

  qwen38-27b-coldfusion-bf16                  stock DavidAU base
  qwen38-27b-coldfusion-abliterated-L35-bf16  Robinson L35
  qwen38-27b-coldfusion-h300-mtp-bf16         Heretic-300 + MTP graft
  qwen38-27b-coldfusion-heretic300-bf16       raw Heretic export

Verified against ZFS used, not df: 4.48T -> 4.33T, ~154 GB. No snapshots were
holding the blocks, all four paths confirmed gone, gen seat unaffected.

The last two were hardlink twins -- same inode, links=2, because the MTP graft
hardlinked every unchanged shard -- so deleting only one would have freed
nothing. `du` across several paths in a single invocation dedupes hardlinks and
reported heretic300-bf16 as 2.5K, which would have made a size estimate wrong in
both directions. Check `stat -c %h` before sizing a delete.

Kept deliberately, so the research record outlives the weights:

  qwen38-27b-coldfusion-bf16.PROVENANCE.txt   pinned HF revision 9c44193f
  coldfusion-abliteration/                    harness, 300-trial Optuna
                                              journal, catatonia-T260.json

With those two, every deleted build is reproducible: re-pull stock at the pin and
replay the winning config.

Held back pending an explicit call: the two NVFP4 quants, h300-nvfp4-mixed (the
only remaining servable copy of the Heretic-300 result) and L35-nvfp4-mixed. The
directive named bf16 weights; these are quants, and there is no storage pressure
arguing for haste at 4.26T free.
 2026-08-21 00:45:54 -07:00
vh 37e9e1ca7f revert(gen-seat): abandon Cold-Fusion, roll back to heresy — the leak is in the base 
Operator directive, given before the result was in: if it's the base, abandon
h300 and the base too. The dose-response said base (18.5% of 22.2%), so it fired.

Live gen seat is /tank/aimodels/qwen38-27b-heresy-nvfp4-mixed again, restored
from .env.bak-coldfusion-L35-20260820. The h300 env is preserved at
.env.bak-h300-abandoned-20260821.

The clincher, same probe pointed at heresy:

  Cold-Fusion stock          P(<think>) 0.1850
  Cold-Fusion L35                       0.2048
  Cold-Fusion h300                      0.2216
  heresy (restored)          not in the top 20, <0.002

A >100x gap between the families, which is why no rollback inside Cold-Fusion
would have helped -- stock and L35 leak at nearly the h300 rate.

Verified after rollback: 0/30 leaks and 0 empty on the same instrument that
scored h300 at 8/30, with the EXISTING enable_thinking:false config; KV pool
403,065 tok / 1.54x, heresy's exact documented baseline; 7/7 aliases; vision
intact. No LiteLLM change was needed, so the chat_template_kwargs fix is left
unapplied -- it worked, but it was a workaround for a base we no longer serve.

Cost, stated plainly: 8/100 refusals becomes 29/100, a 3.6x regression on the
axis the whole Heretic-300 run existed to move. Accepted deliberately.

What carries forward is the methodology, none of which lived in the Cold-Fusion
weights: direction_scope=0 beating per-layer on a merged base, aggression not
being the lever, PR #317 silently dropping the MTP head on save, the MPOA and
sink-screen reasoning, the graft/KL/catatonia/export harnesses, and the finding
that a pristine MTP graft accepts as well as an in-band edit.

New acceptance gate earned here: run think_prior.py on a candidate's STOCK
weights before committing GPU time. It is a ~10s CPU measurement and it would
have disqualified Cold-Fusion before the 300-trial study ever started. Heretic's
objective has no format-compliance term at all -- the same blindness that removed
the self-harm guardrail.

Nothing deleted. Every Cold-Fusion artifact, the 300-trial Optuna journal and
catatonia-T260.json remain on disk. Abandon means stop serving, not rm.
 2026-08-21 00:40:23 -07:00
vh 5ee2325820 feat(coldfusion-abliteration): dose-response settles the <think> leak — base 83%, our abliteration 17% 
Answers "how likely is it that our abliteration caused this?" with a measurement
instead of a prior. P(<think>) at the first generated token, template rendered
enable_thinking=false so the prompt already carries a CLOSED think pair -- the
exact event behind the leak. Raw softmax, bf16, CPU-only, one process per model.
Deterministic: stock reproduced to 17 significant figures across two runs.

  coldfusion-bf16                  none (stock)          0.1850   rank 3
  coldfusion-abliterated-L35-bf16  Robinson L35, mild    0.2048   rank 2
  coldfusion-h300-mtp-bf16         Heretic-300, heavy    0.2216   rank 2

The stock, untouched base already puts 18.5% of first-token mass on opening a
think block the template had closed. Abliteration adds a real, monotonic,
dose-dependent +3.7 points -- a nudge on a pre-existing base, not the cause.
Cold-Fusion is a reasoning-token-compression finetune, i.e. a model trained to
think briefly, and the leak's text shape agrees: a compact correct trace with a
trained transition marker, which is trained behavior rather than damage.

This changes the options. Rolling back to L35 or stock does NOT fix the leak --
at 18.5% under temp 0.7 / top_p 0.8 they leak at nearly the h300 rate. Only
leaving the Cold-Fusion family escapes it, at the cost of the 8/100 refusal
result. The chat_template_kwargs fix is the correct lever.

Durable methodology point: a forward-KL budget cannot catch this. Heretic
minimizes forward KL(stock||abliterated), which is near-blind to the model
putting new mass on tokens stock barely used -- that is reverse KL's job, and we
measured exactly that asymmetry on L35 (reverse 1.43 vs forward 0.70). h300's KL
of 0.0136 is not evidence of innocence. For any "did the abliteration break
behavior X" question, measure P(token) directly.

Ran CPU-only deliberately: 96 EPYC cores and 265 GB of RAM make a 27B forward
pass cheap, so this cost no GPU window and no seat downtime, where the obvious
route was stopping both GPU0 seats.

Also normalizes two more abliteration output dirs from root-owned 0600 to
llmuser 0664. The unreadable-model failure surfaces as FileNotFoundError rather
than a permission error, which is worth knowing before it wastes a run.
 2026-08-21 00:22:11 -07:00
vh 91f4cf22e1 fix(gen-seat): diagnose the unterminated-<think> leak — model defect, temp-triggered 
Operator reported the new Heretic-300 gen seat "sends CoT but never completes
the turn" through Lobe. Diagnosed; not yet fixed (the fix changes gen's
semantics, so it is the operator's call).

The Qwen3.8 chat template appends a pre-closed <think>\n\n</think>\n\n when
enable_thinking is false. The h300 model opens a fresh <think> anyway and never
closes it. Because the prompt already closed the block, vLLM's qwen3 reasoning
parser is not in reasoning state, so the tag passes through as ordinary text --
reasoning_content empty, reasoning_tokens 0, and the whole reasoning-plus-answer
blob lands in content. Lobe then correctly treats the unterminated tag as
still-thinking and renders no answer. The client and the serving stack are both
behaving correctly; the model is not.

The trigger is TEMPERATURE, not presence_penalty (n=12 per arm):

  temp 0.7, pp 1.5  (current gen)   4/12
  temp 0.7, pp 0.0                  4/12
  temp 0.7, pp 0.5                  3/12
  temp 0,   pp 1.5                  0/12

That falsifies the standing hypothesis, recorded in the litellm config comment
and in the operator's own 2026-08-16 note, that presence_penalty 1.5 is the
first dial to move. It is not this bug's cause.

It also explains the blast radius: only the two temp-0.7 aliases leak, `gen`
and `summarizer-large`. summarizer, classifier, image-judge and qwen-image-bench
all run at temp 0 and are clean, so nevermore's summarizer path is unaffected.

Candidate fix, validated n=30 over 4 prompt types plus a 3-turn conversation:
chat_template_kwargs {enable_thinking: true, reasoning_effort: low} takes 8/30
leaks to 0/30, at ~+27% completion tokens and a ~3% empty-content residual.

The tell appears in eval_coldfusion_h300.json and in none of the aeon, heresy,
mixed or w4a16 evals, so it is new with this build -- but L35 was never evaled,
so this does not separate a Cold-Fusion base trait from a Heretic-300
abliteration artifact.

Reproducers and the full method land in bench/think-leak/. Note in particular
that the 7/7 alias smoke test run at cutover structurally could not catch this:
trivial prompts never invite reasoning, so they never sample the leaking token.
 2026-08-21 00:12:30 -07:00
vh 1d3b80169a fix(nevermore): repoint onto live aliases — its LLM pass had been dead 8 days 
nevermore pinned LLAMA_SWAP_MODEL=granite-4.1-8b, an alias retired with the
granite seat on 2026-08-12. Every summarization call since then failed: 67
consecutive status=failure rows, 0 tokens, twice daily, entirely silently. The
briefing had been rendering with no LLM pass at all. Nothing alerts on
status=failure in the spend logs, so it took an unrelated question about
reranker VRAM to surface it.

It was also pinned to NEVERMORE_RERANK_MODEL=qwen3-reranker -- the incumbent
Brokkr R43 measured harming 80/90 fleet queries -- and was its ONLY caller,
while the production `reranker` alias sat at 0 calls for 4 days. The R43
cutover repointed the alias but never moved the consumer.

  nevermore/.env  LLAMA_SWAP_MODEL       granite-4.1-8b -> summarizer
                  NEVERMORE_RERANK_MODEL qwen3-reranker -> reranker
                  (server-only; .env is excluded from the mirror both ways)

Verified against nevermore's exact call shape: summarizer returns clean content
with 0 reasoning chars at temperature 0.2 / max_tokens 4000; reranker scores
0.95 on-topic vs ~1e-5 off-topic; embedding returns dim-1024.

Retired alongside it:

  vllm-rerank    :8002  Qwen3-Reranker-0.6B + the qwen3-reranker alias
  vllm-rerank-a4 :8014  gte-reranker-modernbert + its alias
  vllm-granite   :8004  Exited 8 days, dead service block

and vllm-rerank-a3 was promoted from a throwaway `docker run` into this stack
(the selection ledger's own open follow-up). Healthy in 55s. It keeps the
bake-off arm name so the ledger, memory and R43 record stay valid.

VLLM_VERSION is pinned latest -> v0.24.0. Every service in the stack shares that
one variable, so a bare `compose up -d` could have silently upgraded all of
them at once; both tags resolved to the same local image (4091d5593f77), so the
pin changed nothing at runtime.

GPU1 is down to 81,448 of 97,887 MiB -- 13.9 GB reclaimed tonight.

Correction: an earlier claim that A4 had no gateway alias was wrong. It did.
LiteLLM serves both config-defined and DB-defined models -- live showed 32
against config.yaml's 26 -- and grepping the file cannot see the difference.
/v1/models and /model/info (which flags db_model) are the ground truth. DB
models delete hot via POST /model/delete with no restart.

Left alone: reranker-a3-bge-v2-m3, a zero-call duplicate of `reranker` on the
same backend. It is Brokkr's cutover-verification handle -- redundant rather
than broken, and another agent's tooling is not mine to delete unilaterally.

vh b990951d80 chore(vllm): retire LFM2.5-2.6B permanently; audit finds nevermore on the harmful reranker 
Operator directive: lfm2.5-2.6b goes down permanently.

  - stacks/vllm/compose.yaml   vllm-lfm25 service removed (replaced by a
                               tombstone comment), pushed live to ana-ml2
  - ana-ml2                    container docker rm -f'd, 8,721 MiB freed on GPU1
                               (95,388 -> 86,667 of 97,887)
  - litellm config             lfm2.5-2.6b alias deleted, live + canonical,
                               28 -> 27 models

It was an EVAL-ONLY bake-off seat against granite-4.1-8b that never received
the operator ruling it was pending; the comparator was retired from the roster
on 2026-08-15; it was deliberately never wired into any default or fallback
routing chain; and spend logs show 0 calls in the 4-day window to 2026-08-21.
Weights stay in the shared HF cache -- nothing deleted from disk.

The gateway restart that makes the alias deletion take effect is HELD so it can
batch with a pending reranker change. Until then the name is still routable
in-memory and will error against a dead backend.

Auditing the three reranker seats while answering "why do we have three" turned
up a real problem. The design is one production, one rollback, one fallback --
but the traffic is backwards:

  :8013 A3 bge-v2-m3      PRODUCTION, backs `reranker`     0 calls / 4 days
  :8002 Qwen3-Reranker    RETIRED incumbent, rollback only 7 calls, 12-hourly
  :8014 A4 gte-modernbert "fallback"                       no alias at all

nevermore is hard-wired to the incumbent by name (NEVERMORE_RERANK_MODEL=
qwen3-reranker), so the R43 cutover never moved it -- the cutover repointed the
`reranker` alias and correctly left `qwen3-reranker` naming the Qwen model.
Brokkr R43 measured that model harming 80/90 fleet queries, so nevermore's
twice-daily rerank pass is likely degrading its own briefing.

Fix is one line in nevermore's .env plus a nevermore restart, and it must land
before :8002 is retired. Recorded in persistent-memory with the A4 alias also
noted as absent (global CLAUDE.md names reranker-a4-gte-modernbert; it does not
exist).

vh e3ce713f7f feat(gen-seat): cut over to Heretic-300 — 7/7 aliases, vision intact, MTP 59.7% 
Live GEN_MODEL is now qwen38-27b-coldfusion-h300-nvfp4-mixed (ana-ml2 GPU0
:8015). Served-name left unchanged so all 7 LiteLLM aliases route without a
gateway edit.

Verification:
  KV pool            401,550 tok / 1.53x   (baseline 403k / 1.54x)
  LiteLLM aliases    7/7 green
  vision             3/3 shapes, colour+form+position correct
  MTP acceptance     59.7% median @ 118.37 tok/s
  quality gens       4/4 correct
  abliteration       4/4 compliance
  PPL                NOT measured (see below)

The roadmap predicted ~47% acceptance for a pristine MTP graft versus L35's
59.1% in-band edit. Measured 59.7% on the same harness: there is no acceptance
penalty, which removes the throughput argument for reimplementing MPOA.

A single long-prose generation read 47.5% off the same counters -- below the
8-run minimum of 49.0% -- and would have "confirmed" the prediction by
coincidence. Acceptance must be read from quickbench.py, never one sample.

PPL is blocked on VRAM, not on the model: eval_quality.py aborts with
"prompt_logprobs look uniform" under --speculative-config, and the probe-seat
workaround needs ~22 GB while both cards sit at ~96% committed.

Also normalizes the quant dir from root:0600 to llmuser:llmuser 0664 to match
every other model dir, and records that config.json sha256 is byte-identical
across the h300 and L35 quants and is therefore useless for confirming which
weights are mounted (mtime and a head-hash are the discriminating views).

Rollback is one line to .env.bak-pre-h300-20260820.

vh f90a5025de feat(coldfusion-abliteration): Heretic-300 — 8/100 refusals at KL 0.0136, beats the heresy bar 3.6x 
Ran Heretic v1.4.0's 300-trial TPE search on Cold-Fusion. Best trial scores
8/100 refusals at KL 0.0136 against a 98/100 base, versus absolute-heresy at
29/100 and our hand-tuned Robinson L35 at 72/100 / KL 0.0116 — i.e. 64 fewer
refusals for the same damage. Hand-verified coherent: correct arithmetic with
shown working, clean code, 66-167 word prose across nine probes.

Durable findings:

- direction_scope=0 (single shared direction) is decisive on this merged base:
  n=129, best 8/100. Per-layer directions n=131 never beat 52/100 despite a
  better median. Points against the multi-direction intuition for a diffuse
  direction (our two-template |cos| is 0.62 vs Robinson's 0.99 on stock).
- Aggression is not the lever. r(KL, refusals) = -0.561 over 261 trials; the
  KL<0.02 band contains both the worst results (median 87/100) and the single
  best. A KL 0.3554 trial scored worse than one at 0.0193.
- PR #317 confirmed: Heretic silently drops the MTP head on save. Source 1199
  tensors -> export 1184, all 15 mtp.* gone, vision 333/333 intact, exit 0, no
  warning. This is also why absolute-heresy ships a byte-identical MTP head —
  a bug, not a design choice. Always diff tensor keys after a Heretic export.
- Heretic's recovered direction carries 6.18% of its energy in sink dim 3994,
  versus 0.094% for our L35 and 1.97% for the L39 we rejected as brick-inducing.
  It survives that only because of magnitude-preserving ablation
  (row_normalization=FULL); our plain projection has no such protection, so the
  sink screen correctly refused the in-band MTP graft. Same direction, different
  operation. MPOA is the prerequisite for in-band MTP on a Heretic trunk.
- Heretic's edit is recoverable from weights: delta is rank-1 (s2/s1 ~ 0.010),
  SVD gives the direction, norms give per-layer weights (1.08 -> 1.34, i.e.
  over-projection). Cross-layer |cos| agreement 0.9903 independently confirms
  the single-direction result.

New tooling in services/coldfusion-abliteration/:
  kl_divergence.py    first-token KL, class-split, zero noise floor
  catatonia_gate.py   12 probes x 220 tokens, prints every completion
  heretic_export.py   PTY driver; selects by measured value, never by menu
                      position — Heretic's resume prompt puts "delete the
                      checkpoint and all results" one arrow-key from the target
  graft_mtp.py        recovers the trunk direction by SVD; --pristine for the
                      safe path when the sink screen refuses

Also adds quant playbook 3.13: the NVFP4 recipe sets observer="imatrix_mse" but
llm-compressor has always silently fallen back to uniform MSE for want of
importance data — on this build and on the incumbent. Existing A/B comparisons
stay valid since every build shares the fallback. Parked as id 42.

Guardrail note: this build has lost the self-harm guardrail that the Robinson
L35 build retained. Restoration is the operator's own work item.

vh a9d73dad41 fix(coldfusion-abliteration): GPU0 seat restore order is load-bearing — correct the claim and the runbook 
Restoring the two GPU0 seats with `start meromero; sleep 10; start gen` put
meromero into a 7-restart crash-loop:

  ValueError: Free memory on device cuda:0 (35.3/94.97 GiB) on startup is less
  than desired GPU memory utilization (0.52, 49.38 GiB).

The previous commit's README claimed restore order "is not actually load-bearing"
on the grounds that both seats pass --gpu-memory-utilization as a fraction of
total VRAM. That is half right and the wrong half mattered: the fraction sets the
target, but vLLM gates startup on FREE VRAM and refuses to start unless the whole
target is available. GPU0 runs at ~96.4/97.9 GB with roughly 0.4 GiB of slack, so
the seats coexist only in the order they were originally brought up, and meromero
is the one that does not fit in the remainder. The pre-existing auto-memory note
("gen takes a fraction of free VRAM at startup and will starve meromero") was
pointing at the real effect.

Also: "first" means healthy, not ten seconds earlier. A sleep 10 against a
two-to-three minute weight load is simultaneity, not ordering — gate on observed
state.

Recovery applied: stop gen, wait for meromero healthy, start gen. Verified
against the pre-window baseline rather than against "both green":

  gen KV       14.36 GiB / 403,065 tok / 1.54x  ->  14.34 GiB / 401,550 tok / 1.53x
  meromero KV  542,202 tok                      ->  542,202 tok
  RestartCount 0 on both; summarizer smoke-tested through LiteLLM

Note for the next reader: raw nvidia-smi used-MiB is the wrong check here. It
reads 89,503 now vs 96,376 before, which looks like a 6.9 GB regression and is
allocator slack — serving capacity is unchanged. The anomalous boots were the
high ones (34.95 GiB KV), where gen came up on an empty card mid-window.

vh 1b3fb270e7 feat(coldfusion-abliteration): first-token KL measured — 28.4x selectivity, harmless median 0.0211 
Adds `kl_divergence.py`: first-token KL(stock || abliterated) over the full
248,320-token vocabulary, bf16 vs bf16, scored separately for held-out harmless
and reserved-harmful prompts.

Result (L35, 256 harmless / 104 harmful, answer mode):

  harmless  median 0.0211  mean 0.0364  top-1 agreement 89.8%
  harmful   median 0.5996  mean 0.6992  top-1 agreement 55.8%
  selectivity 28.4x (72.8x in think mode)

Self-KL noise floor is exactly 0.0, and all 720 per-prompt values are
bit-identical between a single-process and a two-process run, so the figures are
signal rather than bf16 jitter. Reverse KL on harmful/answer is 1.43 vs forward
0.70 — the mass-where-stock-had-none asymmetry expected of a refusal-direction
removal. Against the Heretic reference figures (0.1191 prior seat, 0.0759 the
live absolute-heresy seat) this is materially gentler, but those are the other
tool's optimizer output on a different base with its own harmless set and
template — order-of-magnitude, not head-to-head. KL remains a fidelity number;
the viability gate is still MTP acceptance (59.1%).

Method notes:
- Prompt classes are reported separately by design. A single averaged KL over a
  mixed corpus is close to meaningless, since the metric is meant to be large on
  harmful prompts and small on benign ones; the ratio carries the information.
- The harmless evaluation set is drawn from the alpaca pool minus calibration's
  own draw, reconstructed by replaying that draw rather than remembered, and
  asserted disjoint on text. The harmful set is the reserved test split.
- `render` is imported from abliterate.py rather than copied, so the measurement
  cannot drift from the rendering the direction was captured against.
- Batch size 1 with logits_to_keep=1: no padding semantics, ~0.6 MB of logits.

Three corrections to the runbook, each of which cost time:
- "bf16 is 50 GB, only gen must go" was 50.10 GiB mislabelled. Text-only weights
  are 51,300 MiB; freeing either GPU0 seat alone leaves ~50,933 MiB. Both must
  stop. VRAM is now sized from the safetensors headers at run time.
- A 27B model cannot be released in-process: `del` + gc + empty_cache left free
  VRAM at 45,287 MiB, and so did confining the model to an inner frame that
  exits. Only process exit returned the card (96,689 MiB). The first run
  completed only because the allocator hit OOM, collected, and retried. Each
  model now gets its own process, handing log-probs to disk between stages.
- The residency gate read hf_device_map, which transformers leaves empty when the
  model fits on one device — it reported "(unsharded)" whether or not anything
  was wrong, so it could never fail. It now reads parameter devices directly.

Model-agnostic lessons promoted to the quant playbook (new 3.12).

vh 725c8fdf9e feat(coldfusion-abliteration): THESIS PROVEN — in-band-abliterated MTP head accepts 59.1% (beats incumbent ~47%) 
Quantized the L35 abliterated model to mixed NVFP4 and measured MTP acceptance
end to end. The experiment's whole premise: Heretic (the incumbent gen seat)
leaves the MTP head a byte-identical base graft its wrapper never loads, whereas
Robinson abliterates the MTP head in-band — the question was whether that in-band
edit survives well enough to spec-decode. It does, better than the graft:

  MTP acceptance  59.1% median (51-65%, 8 cache-busted topics)  vs incumbent ~47%
  decode          118.7 tok/s median (faster; image-confounded, read as not-worse)
  abliteration    survives quant (creative refusals drop, self-harm guardrail
                  intact, coherent)

Output at /tank/aimodels/qwen38-27b-coldfusion-L35-nvfp4-mixed (22.5 GB). Result
JSON in bench/. NOT cut over — the incumbent seat is untouched; making L35 the gen
seat is a separate decision needing the full Stage-3 gate + real multi-turn hold.

Two env foot-guns hardened along the way:
- quant_mixed_nvfp4.py now promotes text_config attention fields
  (num_attention_heads etc.) to the top-level config for the oneshot, then
  restores. transformers 5.10 / llmcompressor 0.12 (this venv moved under us
  since the Aug-15 heresy quant) no longer delegate the top-level lookup, so
  oneshot raised "Cannot determine num_attention_heads". Same "the fight is the
  environment" pattern as the abliteration capture.
- a sub-~23GB quant saves as a single model.safetensors with no index, so the
  post_quant MTP graft needed an index built first — from the safetensors header,
  not safe_open (which mmaps the whole shard and ENOMEMs on ZFS).

post_quant grafted the abliterated MTP (15 tensors, 849 MB) and re-injected
re:^mtp.* into quantization_config.ignore (llm-compressor pruned it again — the
two-rounds-lost 0%-MTP bug, fired and repaired as designed). Probe served on the
pinned nightly (#51113 qwen3_5_mtp fix) to match the live seat's vLLM.

Flip the in-flight status from 'capture done, calibration expansion next' to
'landed, works'. New detail file captures the three corrected diagnoses (layer-
selection metric, sharding/allocator misdiagnosis, corpus-size falsified) and the
verify/quant work still owed. Supersedes the -capture.md detail file's framing.

vh e9dbc8660b feat(coldfusion-abliteration): abliteration LANDS at layer 35 — separation selector, shard-surgery write, three false diagnoses corrected 
The abliterated model works. A/B vs stock on a matched greedy battery: explicit
sexual + graphic torture (the measured stock refusal surface) go from refused to
complied/engaged, held-out AdvBench prompts loosen, the self-harm guardrail
survives, coherence intact — the Robinson design point exactly. Output at
/tank/aimodels/qwen38-27b-coldfusion-abliterated-L35-bf16, verified bitwise:
131/131 targets changed, 333/333 vision byte-identical (delta 0.0), 735/735
others untouched.

Getting there corrected three diagnoses the prior session had backwards.

1. The layer-selection metric was wrong, and that was the whole ballgame. The
   recipe picks the abliteration layer by peak two-template |cos| agreement. On
   this heavily-merged base that metric is anti-correlated with efficacy: its
   argmax (layer 18) is the WORST-separating layer in the window (Cohen's d 5.51
   vs 9.89 at the peak), and abliterating there was a measured behavioral no-op —
   stock and "abliterated" refused all six probes identically. Cause: the two
   renderings end in different generative modes (</think> vs <think>), so |cos|
   scores answer-vs-reason mode, not refusal, and on a merge the mode term
   dominates. Replaced selection with harmful/harmless SEPARATION (Cohen's d /
   AUC of the direction's projection), gated on the sink screen since separation
   and sink-energy both climb with depth. Picks layer 35 (d 9.35, AUC 0.9997,
   sink 0.094%). Agreement is kept as a printed diagnostic.

2. The "bf16 NaNs, use fp32" rule was a misdiagnosis. The NaN was never
   precision — it was multi-GPU sharding (the residual stream zeroes two layers
   past the GPU0->GPU1 boundary; the first capture's layer 22 happened to sit in
   the healthy region, which is why it looked fine) plus
   PYTORCH_CUDA_ALLOC_CONF=expandable_segments (corrupts retained tensors; the
   corruption MOVED between bit-identical forwards, the tell that it was memory
   not math). On one GPU with a plain allocator, bf16 full-64-layer is exactly
   deterministic and coherent, at 50 GB and 4.3x the throughput of the 111 GB
   fp32 it replaced. Both defects are now hard gates (residency exit 8, allocator
   exit 9); capture pins CUDA_VISIBLE_DEVICES=0.

3. The corpus-size hypothesis was falsified. 52x more calibration data (8->416,
   mlabonne/harmful_behaviors = the recipe's actual AdvBench split, already on the
   box) moved agreement 0.594->0.624 — nothing. Kept the 416/416 corpus anyway
   (calibration.py); it gives the clean separation signal. The held-out 104-prompt
   test split is reserved and asserted disjoint.

Also: the --out write is now shard-level surgery (reads/writes the 18 safetensors
directly, no model object, no GPU). This is correctness, not thrift —
AutoModelForCausalLM resolves to the TEXT model, so save_pretrained would drop all
333 vision tensors AND skip the MTP head (the in-band MTP edit is the entire point
of the Robinson formula). Neither failure raises. Shard surgery makes vision and
the other 1068 tensors byte-identical by construction.

Batched capture with a dtype-aware equivalence gate; hidden states captured via
forward pre-hook (reading output_hidden_states off the returned object is unsafe
here — buffers get recycled). Sharding/allocator lessons promoted to the
quantization playbook (model-agnostic, sections 3.9-3.11 + superseded table); the
selection-metric lesson added to the recipe doc.

The dead layer-18 no-op checkpoint was removed (52 GB, confirmed identical to
stock). Incumbent gen seat untouched. Full canonical refusal-probe re-profile and
MTP-acceptance-on-quant still owed before this becomes a gen-seat candidate.

vh f714f28195 feat(coldfusion-abliteration): Robinson's real 416-prompt corpus, batched capture, two new gates 
The 8/8 calibration set gave |cos| agreement 0.594 against the recipe's 0.9925.
This wires in the corpus the recipe actually used and makes a capture at that
scale affordable.

Corpus (calibration.py, new). The recipe's "held-out train/test split of 416/104
with overlap 0" names mlabonne/harmful_behaviors exactly — 416 train / 104 test,
AdvBench-derived — and it plus harmless_alpaca were already staged in ana-ml2's
HF dataset cache. Read via pyarrow, no datasets dependency, no hub access.
Harmful is order-deterministic (no seed), so a re-capture is reproducible from
the flags alone. The 104-prompt test split is reserved as the held-out
generalization probe and asserted disjoint, so the post-write re-profile cannot
silently become in-distribution. --calib builtin reproduces the legacy run.

Batched capture. 832 prompts x 2 templates = 1664 forwards. Padding is on the
RIGHT: in a causal stack nothing after position t reaches position t, so
trailing pads cannot touch the token read, whereas left padding feeds pads into
the DeltaNet recurrence ahead of the prompt — the path whose torch fallback
already NaN'd once here. Means accumulate in float64; the direction is a
difference of means, which is where cancellation lives on this model.

Gates added, both protecting numbers rather than tensors:
- batch-equivalence: proves padded-batch == single-prompt (rel 1e-3) before
  spending the capture window.
- surgery pre-check: aborts if any of the 131 targets is absent or on the meta
  device. orthogonalize_ edits in place, and an in-place write to an
  accelerate-offloaded tensor is a silent no-op — that ships a half-abliterated
  model past a smoke test.

Fixed a reporting bug: the agreement line printed the global agree.max() beside
the window's argmax layer, so the first capture read as 0.8538 when the real
in-window number was 0.5944. The global peak sits in the early layers where the
dim-3994 massive activation inflates agreement for reasons unrelated to refusal.
Now prints window max, a top-5, and labels the global figure informational.

--max-layer truncates the decoder for capture. Exact, not approximate: a causal
stack's layer-N state cannot depend on layers above N, so any value above the
window top leaves the direction bit-identical while cutting fp32 residency and
forward cost. 46 drops 18 of 64 layers and is what keeps fp32 off CPU offload.
Refused on the write path, where it would emit a truncated checkpoint.

Verified on ana-ml2 without the GPU: dry-run still 1:1 (131 tensors, all
coverage gates), calibration loads 416/416 deterministically with its guards
firing, both --max-layer guards exit as designed. Also confirmed against
chat_template.jinja that enable_thinking=True does resolve reasoning_effort to
xhigh, so the two renderings are the recipe's — template selection was not the
cause of the low agreement.

The re-capture itself is unrun: it needs the fp32 VRAM window and therefore
production seat downtime.

vh 530f1452e8 memory: snapshot — Cold-Fusion abliteration in flight, capture done 
Captures the session's real work as the in-flight focus: abliterating
DavidAU Cold-Fusion with the Robinson formula. fp32 capture succeeded
(finite direction, layer 22, sink-clean) but two-template agreement is
0.59 vs Robinson's 0.99 — calibration-set expansion is the next step.

New detail file records the full saga including the transformers/DeltaNet
bf16-NaN fight (fp32 fix, the causal-conv1d kernel gap, the seat-restart
VRAM-greed gotcha). Supersedes the earlier "watch for DavidAU's heretic
build" posture — we abliterate it ourselves.

vh 7abd3011f7 fix(coldfusion-abliteration): capture works — fp32 forward + finite-gate 
The --capture forward NaN'd repeatedly. Root cause: transformers' Qwen3.5
DeltaNet linear-attention needs the causal-conv1d fast-path kernel, which
can't be built here (no nvcc, no prebuilt wheel). Its torch fallback produces
nondeterministic all-NaN hidden states in bf16 -- same 11-token input finite
on one forward, NaN at layer 4 on the next. bf16 and fp32 share exponent
range, so it's precision-driven catastrophic cancellation, not overflow, and
fp32 resolves it.

Fixes:
- --capture now loads fp32 (the write/surgery path stays bf16 -- no forward,
  no NaN). attn_implementation=sdpa pinned.
- A finite-gate aborts on a non-finite direction. The sink screen alone can't
  catch this: nan > threshold is False, so a NaN direction "passed" it and got
  saved silently on the first run.

Capture result (fp32, full GPU): refusal direction finite, unit-normed, layer
22, sink energy 0.0008% in dim 3994 -- clean, not sink-dominated. Saved.

Caveat recorded: two-template |cos| agreement is 0.59 at layer 22 vs Robinson's
0.99, almost certainly the small 8/8 calibration set vs their 416/104. Valid
but noisier than ideal; the README flags expanding the sets before the write.

README documents the three environment gotchas (fp32-for-capture, the seats
that must be stopped for the 110GB fp32 VRAM and how to restore them, and the
fla side-dir PYTHONPATH) so the next run doesn't rediscover them.

vh 1857a8eb81 feat(coldfusion-abliteration): Robinson-formula harness, gated, staged 
Harness to abliterate DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1 using the
MTP-aware, vision-preserving recipe in docs/pfi/abliteration-recipe-qwen38.md.

Motivation is measured, not assumed: the stock model's refusal profile
(probed 2026-08-19, hand-verified) is ~33% on creative content, concentrated
on explicit-sexual and graphic-torture, with 4/5 hard-harm refused, self-harm
guardrails intact, and zero benign over-refusal. So there is a real
creative-content refusal surface. The Robinson formula is chosen specifically
because it abliterates the MTP head IN-BAND -- which the current gen seat's
Heretic pass does not (its MTP head is a byte-identical base graft the
Qwen3_5 wrapper never loads). That in-band MTP edit is the additive delta.

The script refuses to brick the model. Two hard gates from the recipe halt
before any write: the coverage identity o_proj(16)+linear_out(48)==64 (catches
a tensor-name mismatch that would ship a half-abliterated model), and the
attention-sink screen on dim 3994 (orthogonalizing a direction living there
produces a model that loads, runs, and emits garbage). The direction is
captured from two chat templates and the layer auto-picked by peak |cos|
agreement in [18,45]. Classification is suffix-based and name-agnostic so it
survives minor drift; the coverage gate is the backstop.

Modes: --dry-run (enumerate + gate, no forward, no write), --capture
(direction + sink screen, no write), default (write to --out). The README
sequences dry-run -> capture -> write -> verify, and names the post-checks
(vision byte-identical, refusal re-profile via services/refusal-probe/, MTP
acceptance on the quant, PPL/coherence).

bf16 staged to ana-ml2:/tank/aimodels/qwen38-27b-coldfusion-bf16 (pinned
9c44193, provenance recorded). The destructive run is NOT executed here --
dry-run verification and operator go gate it.

vh ccb56a0a51 docs(pfi): capture the RobinsonLabs Qwen3.8-27B abliteration recipe 
Reference recipe (not a deployed artifact) for MTP-aware, vision-preserving
single-direction abliteration of Qwen3.8-27B -- the base family the gen seat
runs. Captures the two things this recipe gets right that naive abliterations
of this architecture miss:

- The MTP head is abliterated in-band (its two residual-write matrices, glue
  left alone), so speculative acceptance does not collapse on the prompts
  abliteration exists to fix -- directly relevant to the gen seat's MTP>=40%
  gate.
- The vision tower is preserved byte-identical (333 tensors, max delta 0).

Plus the two calibration traps specific to this base: the twice-captured
refusal direction (layer 26, |cos| 0.99) and the attention-sink dimension 3994
that bricks the model if orthogonalized out. Documents the coverage gate
(o_proj 16 + linear_out 48 == 64 layers) that catches a half-abliterated
model before it writes a byte, and the foot-gun that the GGUF imatrix does not
cover the MTP block. Links into model-quantization-playbook.md for the quant
half of the pipeline.

vh 7010f9a1da feat(booth): render .md/.txt/.log inline in the gallery, collapsible + closable 
Docs used to render as a clumsy link that navigated to a separate page. They
now render in place: build_gallery pre-renders each doc (markdown -> HTML,
plain text raw) and the gallery shows it inside a native <details open>
disclosure that spans the full grid width so prose has a readable measure.

The doc bar carries: a collapse chevron (the whole <details> summary toggles,
works with JS off), a full-page link (still reaches the standalone viewer), a
download link, and a session-close ✕. The ✕ needed stopPropagation +
preventDefault because it lives inside <summary> — otherwise its click would
toggle the disclosure instead of hiding the item. Close is JS (progressive
enhancement); collapse is native.

Two design points:
- Plain text is returned RAW from build_gallery and escaped by the template
  inside <pre>. Pre-escaping in Python plus Jinja autoescape would
  double-encode angle brackets; a test pins the single-escape.
- Inlining is bounded by DOC_MAX_BYTES. A doc over the limit keeps the old
  link-out behaviour rather than being rendered into every index load; a test
  covers the fallback.

The shared .markdown-body / .textview typography moved from doc.html's scoped
<style> into base.html so the inline body and the full-page view render
identically; doc.html keeps only its page-layout wrapper.

Updated the pre-existing test_gallery_links_docs_to_view: it asserted the old
link-out behaviour the operator asked to change, so it now asserts the inline
render plus the surviving full-page and download affordances. 61 pass.
Verified live: markdown renders with headings/table/blockquote/code, txt
preserves whitespace and single-escapes, collapse and ✕-close both work.

vh 40257247b0 memory: IPv6 plan settled — endpoints not internal numbering; ESH has a /56 
Corrects three claims that had been standing in the fleet IPv6 notes and that
sent a three-arm research effort after a problem that did not exist:

- ESH was recorded as having no IPv6. It has a /56 delegated and a routable
  WAN GUA -- substantially more prefix than NH3's single /64.
- The mesh was recorded as broken by ESH's CGNAT. It is not and was not down;
  ESH is outbound and working. CGNAT on v4 alongside generous v6 is just the
  modern ISP pattern, not an outage.
- IPv6 was framed as the escape hatch for that outage. The actual plan is that
  IPv6 carries tunnel ENDPOINTS for Site Magic and WireGuard, and LANs are not
  numbered in v6 at all.

NH3 internal v6 was brought up on the delegated /64 and verified end-to-end
(global GUA on nh3-docker, zero loss to Cloudflare and Google v6, un-NATed
source address seen from outside), then reverted on operator direction: one
/64 lights exactly one VLAN and that is not worth the split-brain.

The AT&T prefix research is kept as reference rather than deleted -- the /60
is real but undelegatable, the living multi-prefix mechanism is multiple
IA_PD in one solicit rather than the VRRP/multi-MAC recipe we were handed,
and the UDM SE can express neither. That is the answer if NH3 LAN-side v6
ever earns a maintenance window; it is not on any critical path now.

vh 6770ba26d6 feat(booth): kept boards — a .forever sentinel and a standing link board 
Agent sessions hand the operator URLs and they drown in terminal
scrollback. The Booth is the right home for them — it already has the one
property that decides adoption, which is that a session can publish with
mkdir and cp, no API key, no schema, no deploy — but everything in it dies
in 24h.

So: a booth containing `.forever` is never swept, and renders in its own
Kept lane at the top of the index. Opt-in per booth, so the ephemeral
default is untouched and nobody inherits a cleanup chore. `rm` the
sentinel and the board rejoins the sweep; the CLI verbs are sugar over
exactly that, which keeps the filesystem-is-the-state model honest.

The pin is deliberately NOT wired into is_expired(). That stays a pure age
question feeding the `expires_in` countdown; only sweep_once() honours the
sentinel. Keeping expiry arithmetic and reaper policy apart means they
cannot drift into each other.

Kept cards are visually separated per Australis: a 2px top edge in aurora
blue, the one accent border the system sanctions. They show "kept" instead
of a countdown, and they deliberately lose the one-click wipe button — a ×
next to the durable stuff is a footgun, so removing a kept board is a
two-step act.

`booth link <url> [description]` appends to the standing `links` board,
creating and keeping it on first use. Entries carry provenance (handle or
hostname, plus a timestamp) because a bare URL is unreadable three days
later. The append is one printf of one line to an O_APPEND fd — atomic
under PIPE_BUF on POSIX — which matters because many agents post to one
board and interleaved half-lines would be the obvious failure mode.

Seven tests cover the sentinel: detection, survival of a sweep that wipes
its neighbour, the deliberate is_expired/sweep_once split, the listing
flag, the sentinel not inflating item counts, and both lane-rendering
directions. Two of them originally asserted on the bare strings "Kept" and
"kept-grid", which passed for the wrong reason — those also appear in the
inlined stylesheet served on every page — so they now assert the full
class attribute. 55 pass.

Also corrects the Homepage card's description, which advertised a flat 24h
TTL that is no longer the whole story.

vh 23cccf5f53 fix(homepage): force the canvas clear of the cached wallpaper div 
Removing the `background:` block from settings.yaml was not sufficient.
Homepage server-renders the wallpaper as an INLINE style on
`<div id="background">` and Next.js caches the rendered page, so the aurora
survived both the config removal and a container restart. Only a full
recreate clears that cache, and recreating this container costs an hour of
missing tab bar and i18n before it heals itself.

Adding `#background` to the canvas reset is deterministic and immediate,
and it also keeps the canvas correct if the setting is ever re-added by
accident. The existing selector missed it: the DOM is
body > div#__next > div#background, so `body > div` matched the Next.js
root, not the wallpaper layer.

Verified live rather than locally: the served page now reports no
background image, with all three canonical faces loaded and the group
eyebrows rendering as JetBrains Mono in Australis cyan.

vh b271db1f44 feat(homepage): rebuild the theme on canonical Australis tokens 
The predecessor theme was ugly for two structural reasons, not one.

It did not use the design system's colours. It built a parallel OKLCH
palette "derived from the Australis philosophy" and swapped the canonical
typeface for Supreme -- a fork, not a theme. Every hex here is now copied
verbatim from ~/.claude/skills/australis-design/colors_and_type.css, and
build.py re-checks all 19 against that file at build time and warns on
drift so it cannot quietly fork again. Type is the canonical stack: Space
Grotesk / Inter / JetBrains Mono, vendored as latin-subset VARIABLE woff2
(one file per family, 102 KB total against 56 KB for three static Supreme
cuts, and no Google Fonts request at page load).

It also carried a generated full-bleed aurora image behind the entire
dashboard. Canon forbids exactly that -- "solid fills only on chrome, no
full-bleed photography, no decorative gradients", and the aurora motif
"never as a background fill behind text". The predecessor knew, said so in
its own header, and dialled the opacity down rather than dropping it. The
image is gone; the aurora survives as a 1px accent edge under the tab bar,
which is where canon sanctions it. The asset stays in images/ in case it
is ever revisited.

Direction is instrument panel. Group headings become the Australis mono
eyebrow with a hairline to the right edge -- canon calls the eyebrow a
system signature, and it turns the groups into register bands instead of
headings floating over a grid. Status stops shouting: the filled emerald
chips read louder than the service names they annotated, so they are now a
semantic dot plus a mono micro-label at tertiary contrast. Cards are
bordered and opaque, per canon's border-over-shadow rule for chrome.

Alignment, per operator feedback that pills and cards did not line up:

- The status cluster is centred on the service name's line rather than
  parked in the card's top-right corner, where Homepage's `absolute top-0`
  left it floating ~7px above the title's optical centre. The offsets
  reconstruct the title line box and are documented as moving together.
- Descriptions get a two-line minimum, so the common one-line/two-line mix
  bottom-aligns across a row. This is what made the grid look ragged.
  useEqualHeights stays false: it inflated short cards to match a widget
  card twice their height, which was the worse failure.
- The status dot is flex-centred rather than nudged with vertical-align,
  so it stays centred if the type scale changes.

Retires the Skyfall sources and the Supreme faces; theme/ now has one
source of truth.

vh b92097688c fix(esh-pve): hardware watchdog, and close the single-resolver DNS SPOF 
esh-pve hard-froze at 03:34 on 2026-08-19 and stayed frozen ~4.5 hours
until a manual power cycle. No panic, no OOM, no MCE — the journal stops
mid-operation. The whole ESH site lost DNS with it, because esh-userland
(VLAN 10, the PVC SSID and wired userland LAN) was handed exactly one
resolver: 10.0.50.45, AdGuard on esh-docker-vm, on a different VLAN, with
no secondary. Internet and routing were healthy throughout.

Two fixes.

1. DNS: 10.0.10.1 (the gateway, verified resolving) added as secondary on
   esh-userland via the UDM Classic API. Note this is degradation cover,
   not clean failover — clients that query resolvers in parallel will
   bypass AdGuard for a share of lookups.

2. Watchdog: softdog -> iTCO_wdt under systemd (RuntimeWatchdogSec=60),
   watchdog-mux masked. The box looked watchdog-protected and was not: a
   software watchdog cannot fire when the kernel it lives in is wedged,
   and watchdog-mux only pets the device while an HA client is connected,
   which never happens on a cluster with no HA resources. Firmware does
   not block the TCO timer here, checked before committing to it.

Also pins VM 102 off (onboot: 0). It starts with full GPU passthrough and
vfio-pci enabling that device is the last thing the kernel logged, 39
minutes before the freeze. The other suspect is the kernel itself: the
host ran 4.5 months on 6.8.12-16, took 6.8.12-42 in an apt batch on
08-18, and died 20 hours into the first boot on it. 6.8.12-16 is still
installed as the rollback.

The playbook is idempotent — a second run skips all six steps and passes
all six verifies. The watchdog is confirmed armed (identity=iTCO_wdt,
state=active, held by PID 1) but has NOT been observed firing; proving
that needs a deliberate wedge.

Memory also corrects two wrong mid-incident calls: the mgmt VLAN is
routed over the site tunnel and is not firewalled off — both symptoms
were the dead host generating ICMP unreachables.

vh 059f963118 docs(waterland-studio): note why an adopted job shows as failed 
waterland-dev confirmed the mechanism: adoption marks a job failed on a
sidecar saying running/queued, or on a directory with no plate.png. The
pre-header-fix renders died 1.7s in with a source and no plate, so they
land in the second branch. Recorded so nobody investigates adopted
history as a live fault.
 2026-08-19 01:40:52 -07:00
vh e6907819b0 feat(waterland-studio): deploy b72425b — all three upstream findings fixed 
One update.sh run on irv-ml1 carried both open upstream PRs, per the
operator's green-light on the job-store fix:

- #5 (464dfc2) declares cupy-cuda12x[ctk] on the gpu extra and takes uv
  out of the render path (sys.executable -m waterland.cli), retiring the
  runtime prune trap at the source.
- #6 (b72425b) rehydrates the job index from the data volume at startup,
  fixing the unbounded store growth reported from this side.

Verified after the update rather than assumed: healthy on backend cupy;
/api/jobs went 1 -> 16 against 16 directories on disk, so API and volume
agree for the first time; nothing wrongly reclaimed, correct since 16 is
under RETAIN=40 and adoption only makes them visible; a real 256^2 plate
render completes warm, so the kernel-cache volume survived the image swap.
A subsequent render took both counts to 17.

The image keeps its explicit [ctk] install and UV_NO_SYNC/UV_OFFLINE pins
even though both are now redundant. The header requirement is a property
of this slim base, not of the upstream extra, and the cost is measured
rather than assumed: uv sync satisfies it first, so the line reports
"Audited 1 package" and adds 0.3s to the build. The env pins are now
cheap defence-in-depth against any future path that re-enters uv.

Docs corrected in place: the README's upstream-finding section is now a
resolved-finding record, and the two "bounded ~500 MB" claims say which
commit made that bound hold across restarts rather than only within a
process. Comment-side changes pushed to the live compose dir; no restart
was needed for them.
 2026-08-19 01:39:13 -07:00
vh a2b6bf409e memory: waterland-studio upstream fixes landed, container stays pinned 
waterland-dev merged PR #5 (main now 464dfc2), fixing both landmines at
source: the gpu extra declares cupy-cuda12x[ctk], and the renderer spawns
sys.executable -m waterland.cli instead of re-entering uv mid-job.

The running container deliberately stays on 8025366. Its own [ctk] install
and UV_NO_SYNC/UV_OFFLINE pins already neutralise both defects, so a rebuild
would buy reliability that is already present — and the project is in
wind-down. Both guards are kept rather than dropped: the header requirement
is a property of this slim image, not of the upstream extra, and the uv pins
are now cheap defence-in-depth against any future path that re-enters uv.

Also records waterland-dev's confirmation of the unbounded job-store growth
and the operator's green-light on their startup-rehydrate fix. That PR
merging is the rebuild trigger: one update.sh run lands the rehydrate and
464dfc2 together. Marks the inbox drained.

vh bc3aada73a memory: snapshot — .internal DNS live, waterland containerised, homepage themed 
Captures a long infra session: fleet *.internal DNS (git-sourced, 42 names,
three resolvers including a new colo one), waterland studio containerised on
irv-ml1, Homepage cleaned up and themed with Australis Skyfall over an
Arbo-generated background, and four unmanaged stacks adopted into stacks/.

Four detail files added. Auto-archived 4 entries to archival-memory.md
(Recent decisions 2, Tried and abandoned 2); 5 held back by the open-deferred
guard rather than moved.

Also records three operator-owned open items: the colo DNS repoint, the
static-v6 convention, and the deliberately belayed AI-tab Dormant regrouping.
 2026-08-19 01:20:53 -07:00
vh b8003c73ae feat(dns): fleet .internal naming — git-sourced, agent-managed, three resolvers 
Names for fleet hosts so addresses stop needing to be memorised. Built because
IPv6 makes that hopeless — and, more to the point, because v6 addresses are
derived rather than assigned, so they cannot reliably be written down once and
trusted either.

  dns/internal.yaml     source of truth: 38 hosts + 4 service aliases
  scripts/dns-sync.py   reconciles AdGuard resolvers against it
  stacks/adguard-ana/   the colo's resolver, which did not exist

Naming is <host>.<site>.internal with sites ana/esh/nh3 (operator's call).
.internal is ICANN-reserved for this; .local is reserved for mDNS, which is
why searxng.pfi.local was a collision that merely happened to work.

Same posture as deploy-stack.sh: file is intent, resolvers are derived state,
you see a diff before anything changes. Every name is published to every
resolver, so the site label says where a host IS, not who knows about it.

Two properties that matter:
- Authority is scoped to the ZONE, not the resolver. ESH carries hand-made
  esteban.net rewrites predating this; they are read, ignored and preserved.
  Resolver-wide authority would have silently deleted them.
- Within .internal it IS authoritative, so UI-added names get removed. That is
  the point — one place to look.

Colo gap closed: ana-docker had no resolver at all (hosts went straight to
1.1.1.1). Its AdGuard runs API on 8053 because 8080/3000 were taken, so the
port is carried per-site in the yaml rather than assumed by the script. It
ships with no blocklists — a false positive on a server network breaks
service-to-service calls for no upside.

Auth is a dedicated infra-ops AdGuard user, not the operator's account,
password vaulted at nh3-dev/adguard-infra-ops-password. Pre-change configs
backed up on each resolver. Both resolvers stayed answering across the restart.

searxng.pfi.local -> searxng.ana.internal, with the old Host() kept alongside
so nothing breaks mid-migration. matrix.pfi.local deliberately NOT migrated: a
Matrix server_name is baked into every user id, room id and signing key, so
renaming it rebuilds the homeserver's identity rather than changing a DNS name.

The v6 column is empty and correct — no fleet host has a global v6 address
yet. The file documents why addresses must be pinned statically before they go
in, since a record that silently stops matching is worse than no record.
 2026-08-19 01:10:55 -07:00
vh 8189076daf docs(waterland-studio): claude-bot read grant wired, and an upstream store-growth finding 
Operator granted claude-bot read on vh/waterland; verified scoped correctly
(admin false, push false, pull true). Token is on irv-ml1 at
/root/.config/waterland-studio/git-credentials, 0600 root-owned, wired as a
REPO-SCOPED credential helper rather than a global one, and .git/config holds
no token so the remote stays clean in any diff or backup. The vh site-admin
token was used only for the initial clone and the grant itself and was never
written to disk on that host.

update.sh now runs end to end: fetch, rebuild, recreate, health. Verified the
kernel-cache volume survives a recreate (warm 256^2+anim render 6.6s straight
after) and the job store survives with all 16 directories intact.

Records an upstream finding surfaced by that check: JobStore._jobs is
memory-only and nothing scans the data dir at startup, so after a restart the
API lists only new jobs while old ones persist on disk — cosmetic — but the
RETAIN=40 eviction only sees in-memory jobs, so restart-orphaned directories
are never reclaimed. The handover's ~500 MB bound holds per process lifetime,
not across restarts. Reported to waterland-dev; upstream's call to fix.
 2026-08-19 00:47:38 -07:00
vh a2b5b58eee feat(waterland-studio): containerise the GPU render service on irv-ml1 
Replaces a bare nohup on irv-ml1:8410 that would not have survived a reboot,
handed over by waterland-dev. Tracks vh/waterland @ main (PR #4 merged; main
HEAD is exactly the pinned 8025366).

Build context is a checkout at /opt/waterland-studio/src, deliberately OUTSIDE
the compose dir — deploy-stack.sh rsyncs stacks/<stack>/ with --delete and
would otherwise eat it. The Dockerfile is passed out-of-context.

Three landmines, all measured:

1. Both uv extras are load-bearing at build AND run. jobs.py shells the
   renderer out as a literal  with no --extra flags, so uv
   would re-sync at runtime and prune cupy — silently dropping to the numpy
   path at ~21x wall time. UV_NO_SYNC pins it; UV_OFFLINE makes any failure
   loud instead of quietly slow.

2. cupy needs CUDA HEADERS for its NVRTC compile, not just the driver and the
   wheel's runtime libs. The host has a system CUDA toolkit so the nohup
   process found them by accident; a slim image does not, and every render
   died 1.7s in with 'Failed to find CUDA headers' printed through argparse's
   usage banner — which reads like a CLI bug, not a missing toolkit. Fixed
   with cupy-cuda12x[ctk] (hundreds of MB, vs ~6 GB for a -devel base).

3. The A6000 is host device 1 but container device 0, since compose exposes
   exactly one GPU. CUDA_VISIBLE_DEVICES_TARGET=0 inside; copying the host's
   value selects a device that does not exist.

/root/.cupy is a volume because the NVRTC compile costs ~17s: verified at
23.3s cold vs 6.1s warm, and re-verified across a restart (23.2s on a fresh
cache volume, 6.0s once populated). Warm 256^2+anim beats the 7.4s recorded
against bare metal, so containerising cost nothing.

Job store seeded with the 4 jobs from the displaced instance. Serial by design
(one replica, one card) and unauthenticated, so it stays LAN/WireGuard-only.
 2026-08-19 00:42:12 -07:00
vh df68dd2753 style(homepage): tone the stat values down, run the aurora through the page 
Two operator corrections in one pass.

Stat values overshot: the previous commit took them from font-thin 13px to
bold 22px in heading white, which went from whisper to shout. A stat only has
to out-rank its own label, not the service name above it — now --text-md at
medium weight in cyan, which clears the label but sits below the card title
where it belongs.

Colour lift, staying inside the system rather than around it: Skyfall names
Aurora (blue, cyan, green) the PRIMARY families, 'used generously, in that
order', while Dawn (amber, red, violet) is semantic-only. So group markers now
cycle blue -> cyan -> green down the page — icons at full strength, names at
0.72 — service icons take a single cool wash, header resource icons go cyan,
and latency tags move to the info family so 'how fast' stops looking like
'is it alive'. No Dawn colour is used decoratively anywhere.

Also fixes selectors that never bound: Homepage emits docker-status-<state>,
not status-<state>, so the green pills up to now were stock colouring rather
than this file. Both forms are matched and the trap is commented.

README records the iteration loop that would have caught the overshoot: CSS is
served per-request, so it needs a reload, not a recreate and not the layout
warm-up — and candidate CSS can be injected into the live page for a
seconds-long feedback loop instead of a 10-minute one.
 2026-08-19 00:25:02 -07:00
vh f38cf69fe4 fix(homepage): invert the widget stat hierarchy — numbers lead, labels recede 
Stock Homepage builds each stat as a font-thin (weight 100) 13px value above a
font-bold 12px uppercase label, so the number you actually came to read is the
quietest thing in the card while its label shouts. Skyfall's rule is that
hierarchy comes emphatically from weight AND size, and that numbers are data.

Value now renders at --text-xl bold in tabular mono at --text-heading; label
drops to a --text-2xs tracked eyebrow at --text-faint. The well itself moves to
--surface-input, one step DOWN from the card it sits on, so stats read as inset
data rather than as another floating surface — a recess, so it takes the
hairline without the shadow.

Also drops .service-block from the generic .service-tag rule, which was what
pinned every number to --text-2xs in the first place.

Visible on Plex, Jellyfin, PaperlessNGX and Uptime Kuma.

vh dc3e47b3a2 feat(heretic2-charrp-reasoning): track the NVFP4+MTP reasoning seat 
The char-rp-reasoning seat on ana-ml2 GPU0 — NEO-CODE Heretic2 27B at modelopt
NVFP4 with a grafted BF16 MTP head, ~77 tok/s via qwen3_5_mtp spec-decode,
replacing the retired GGUF seat. It had been running untracked.

Includes conf/mtp-workaround/sitecustomize.py, which is not optional: vLLM
0.24.0 does not propagate modelopt exclude_modules to the spec-decode DRAFT
model, so the BF16 MTP head gets quantized and the engine dies at load. The
shim force-skips mtp.* in is_layer_skipped. Both the mount and PYTHONPATH are
load-bearing.

Adds the two files house convention expects and the directory lacked: a
.env.example naming every knob (all values are the compose defaults; the live
host overrides only the three VRAM ones) and a README that points at
docs/runbooks/heretic2-nvfp4-mtp-seat.md rather than duplicating it.

No secrets: API_KEY is empty by default and the real .env stays on the host.

vh 45c1995d7a feat(homepage): Australis Skyfall theme + Arbo-generated aurora background 
Replaces the previous theme attempt, which was built on a misread: the ask was
to use Arbo as an IMAGE-GEN ENGINE for the background, with the operator's
Australis Skyfall design system supplying the palette.

theme/ holds the source — colors/layout/typography vendored verbatim from the
Skyfall handoff bundle, Supreme 400/500/700 woff2, the Homepage bindings in
skyfall.css.in, and build.py which inlines fonts + tokens into
conf/custom.css. custom.css is GENERATED; edit the .in file and rebuild.

The build exists because Homepage serves only custom.css and custom.js out of
its config dir, so a @font-face pointing at a vendored woff2 would 404 — the
face has to arrive as a data: URI. The background image takes the other route:
/app/public/images is a real static route, so compose.yaml now mounts
images/ there read-only and settings.yaml points at /images/.

Bindings map Skyfall's semantic layer onto Homepage's DOM: Sea surfaces, the
depth recipe (hairline AND two-layer shadow, never one alone), uppercase
eyebrow group headers, the sanctioned accent-rail on the active tab rather
than a glow, and semantic status colour so a green pill means the service is
actually serving.

Background generated by Arbo (irv-ml1:8201) workflow t2i-ui-background, job
13f0891f4e42, seed 26, flux2-klein-9b, 2048x1152 — abstract, no subject,
cool-temperature aurora. 1.6 MB PNG -> 22 KB WebP.

Two deviations are documented rather than hidden: Skyfall forbids imagery
behind body text (held at opacity 30 as mitigation), and service icons stay
full-colour vendor logos.

NOT DEPLOYED — live still runs the old theme. Prototype on :5199.
 2026-08-18 23:30:27 -07:00
vh c3de7dbd58 feat(homepage): add Arbo 'Raven' theme to custom.css; correct the tab-bar note 
Ports Arbo's design tokens (irv-ml1:8201) into conf/custom.css — flat raven
ink #021425, card surface #112333 on #1B2E3D borders, Manrope, and mint
#2FFC89 reserved for signal so a green pill means the service is actually
serving. Values read off Arbo's running :root custom properties rather than
sampled from a screenshot. CSS rather than settings.yaml because Homepage's
color: setting only accepts built-in Tailwind ramps.

NOT YET DEPLOYED — live still runs the stock theme pending an A/B decision.
Prototype is at 10.0.50.45:5199; shots in ~/booth-data/homepage-cleanup/.
Promoting it also means dropping the background: block from settings.yaml.

Also corrects the previous commit's tab-bar claim. It is not a fixed few
minutes of warm-up: a fresh container was still tab-less at 4m30s twice, and
recovered on its own about an hour later. Cause remains unpinned; the README
now records the measured timing and the four ruled-out causes.

vh 42c594c29f fix(searxng,seafile): repair wget healthcheck argv, restore seafile after 3-month outage 
searxng: the healthcheck passed '--tries' and '--spider' as separate argv
entries, so wget consumed '--spider' as the value of '--tries'. Spider mode
never engaged and every 30s probe downloaded the response to disk; the
container's working directory had accumulated 295,287 healthz.N files since
April, and the directory scan to pick the next free filename is what
intermittently blew the 10s timeout and flapped the dashboard card to
UNHEALTHY. Restored '--tries=1'. The junk was in the writable layer, so the
recreate cleared it. Now healthy, fails=0, 200 in 0.16s.

seafile: none of the three services declared a restart policy, so Docker
defaulted them to 'no'. The daemon stopped all three within 200ms on
2026-05-06 and nothing brought them back — a three-month outage whose only
trace was an EXITED card. Exit 255 is what a container ignoring SIGTERM
reports when the daemon stops it, not a crash. Added restart: unless-stopped.
Stack is back up; mysql gates on its healthcheck as designed and seahub
started without the race. 302 -> login page.

Both stacks were running unmanaged on ana-docker and are now tracked here.

homepage: AI tab reordered by clickability per operator — chat frontends,
ComfyUI and the control plane on top; vLLM /docs seats and TTS endpoints
below. Corrects the previous commit's UNRESOLVED tab-bar section: it was
warm-up time after a recreate, not a defect.
 2026-08-18 22:27:15 -07:00
vh 9d92c4bd21 fix(homepage): pin UltraSeedbox to one tab, dedupe Uptime Kuma, size columns to members 
UltraSeedbox had no layout: entry, and Homepage renders an untabbed group on
every tab — eight full-width bookmark bars repeated four times. Pinned to Main
with a row layout.

Uptime Kuma rendered twice: a manual services.yaml block under Monitoring plus
homepage.group=Apps on the container. Dropped the manual block, moved the
label to Monitoring, added homepage.siteMonitor. Adopted the previously
unmanaged uptimekuma stack into stacks/ so the label is version-controlled.

Column counts declared more columns than groups had members, leaving the last
row of several groups mostly empty. Columns now track member counts.

Also records an UNRESOLVED regression: since the container was recreated the
client render has lost its tab bar, wallpaper and i18n. Ruled out the config
changes (committed pre-cleanup config reproduces it) and v2.0.0 (v1.13.2
reproduces it). Server HTML still carries the tab markup, so the loss is
client-side. Details in the stack README.

vh 084ad924f0 memory: snapshot — ESH fiber live, esh-pve-nas migrated+patched, v6 mapped 
Session captured: ESH cut over to Cityside 2Gb symmetric fiber and was
fully provisioned on it; esh-pve-nas completed its ZFS-root migration off
the USB DOM and took its 225-package security backlog with the reboot
deferred; ESH<->colo IPsec was rebuilt as a dialup tunnel with NAT-T after
CGNAT broke the statically-pinned one; IPv6 was mapped across all three
sites.

Auto-archival fired at the soft cap: 7 entries moved to
archival-memory.md (Recent decisions 3, Tried and abandoned 4), all
verified-complete arcs, with two detail files moved and removed. The
remaining pre-Aug-05 entries were held back by the open-deferred-work
guard, so the index stays slightly over cap at 313 lines rather than
losing a live pointer.

Also records the one self-inflicted outage of the session (missing
--make-rslave on a chroot rbind) and that three long-dead things
surfaced incidentally: pvestatd down 82 days, a vzdump hung 126 days,
and a VM sitting in prelaunch for four months.

vh 34d3f42bf5 docs: park the BGW210 v6 work pending the Device Access Code 
Operator will retrieve the BGW210 Device Access Code from the NH3 office
and vault it, after which the IPv6 LAN settings page can be driven
remotely.

Parked on the henge as reclaim-nh3-s-7-unclaimed-ipv6-64s-from-the with
everything needed to resume cold: the verified facts about the /60 split
and the seven unclaimed prefixes, why AT&T cannot fix it, the exact page
to start at, what to look for in priority order, the other settings
pages behind the same login, and the wpa_supplicant fallback with its
warning about modifying NH3's only uplink.

Suggested vault path unifi/bgw210-nh3-device-access-code, matching the
existing unifi/* credentials.

vh 57e080319b docs: NH3 v6 root cause is the BGW210, and seven /64s are unclaimed 
Operator suggested checking the BGW on its 192.x management address,
which turned out to give the whole picture from unauthenticated status
pages.

The CPE is a BGW210-700 on firmware 4.28.7 at 192.168.1.254. AT&T does
hand it a /60 -- c110 through c11f. The BGW keeps c110-c117 for itself
and re-delegates up to eight individual /64s on c118-c11f, top-down. Our
UDM holds c11f, delegation number eight.

So the earlier conclusion that AT&T only grants a /64 was right about
the symptom and wrong about the cause. Seven further /64s are available
and simply never solicited, because UniFi exposes a single
wan_dhcpv6_pd_size integer with no field for how many prefixes to
request. The documented workaround is repeated -P flags to dhclient,
which the UniFi UI cannot express.

This also settles that an AT&T ticket cannot help: the rationing is CPE
firmware behaviour, not provisioning. Records the two real options --
accept one /64, or bypass the BGW entirely with wpa_supplicant EAP-TLS
on the UDM to negotiate the full /60 -- with the warning that the latter
modifies NH3's only uplink and needs a planned window.
 2026-08-18 16:27:09 -07:00
vh 1b6c26ce58 docs: AT&T PD is a hard /64 at NH3, tested on the wire 
AT&T support guessed 'I do not believe att will do that' from a DNS
provisioning desk. The guess was correct, but it needed proving rather
than accepting, so the UDM solicited DHCPv6-PD at /48, /56 and /60. All
three returned the same single /64. This is not a case of nobody having
asked -- the ask was made three ways.

Proven by temporarily enabling PD on nh3-iot, the only NH3 VLAN with
zero clients, then setting ipv6_pd_prefixid to 0, 15 and 16. All three
returned an identical c11f prefix, which only happens when exactly one
/64 is delegated; with a larger block the prefix-id moves the LAN within
it.

Records a mistake worth not repeating: I first read the gap between the
WAN address (c110) and the delegated prefix (c11f) as evidence of a /60.
It is not -- AT&T assigns those from different parts of their pool and
the spread means nothing.

NH3 was fully restored afterwards, with rollback artifacts kept. Also
captures the concrete ask for AT&T Business, phrased as something their
provisioning team can verify against their own DHCPv6 logs, and the
consequence if refused: NH3 can host exactly one v6 segment against
ESH's 256.

vh fddf7f587f docs: record the pending Cogent IPv6 provisioning request for the colo 
Operator opened a ticket with Cogent for v6 at Anaheim, which closes the
one thing tonight's investigation could not resolve from our side.

Captures the diagnosis so the ticket has evidence behind it: a single RA
in 90 seconds of sniffing wan1, from fe80::ea0a:b9ff:fe3b:2c16, proving
an IPv6-capable router sits one hop away on the circuit terminating
38.120.12.42/29 -- but SLAAC obtained no global address across multiple
RA intervals and ping6 to Cloudflare and Google both returned 100% loss.
Router present, circuit unprovisioned.

Also records that the FortiGate v6 config was fully reverted after
testing, the FortiOS gotcha that SLAAC is 'set autoconf enable' rather
than an ip6-mode, and the ask to make when it lands: a /56 or better,
since NH3 only receives a single /64 from AT&T.

Notes the consequence worth planning around -- once provisioned, the
colo becomes the only site with both a static public v4 and routable
v6, which makes it the natural v6 hub given ESH is CGNAT'd and NH3 is
prefix-constrained.
 2026-08-18 14:20:15 -07:00
vh fb91ea759e docs(pfi): lesson 10 -- v6 collapses two exposure controls into one 
Operator's framing, and it is a better argument than the terminology
correction that preceded it. Under v4, exposing a host needed two
affirmative acts -- a DNAT and an accept rule -- so missing either left
the host dark. There is no v4 misconfiguration that exposes an internal
host by accident. NAT was load-bearing security whether or not anyone
designed it that way.

v6 removes the first control entirely. The path exists inherently, so
the firewall is the only thing left, and the failure mode inverts from
fail-closed to fail-open. Rule-ordering slips, rulesets that silently
match only one address family, new VLANs added without policy, and
re-delegated prefixes unmatching address-literal rules all become
exposure events rather than no-ops.

Records the practical consequences: key rules on interface/zone rather
than address literals, treat enabling v6 on a segment as requiring
policy to exist first, and verify default-deny from off-net rather than
by reading the ruleset -- which is lesson 3's assert-the-effective-value
discipline applied to firewall policy.

Also corrects my own claim from the previous commit that the pending
firewall pass was 'smaller' than I had implied. It is not smaller, it is
different in kind.
 2026-08-18 13:41:23 -07:00
vh 707a8cbcce docs: correct addressable vs reachable in the ESH v6 entry 
I wrote that enabling SLAAC would give LAN devices 'globally reachable
addresses'. Wrong word, and the wrong word in a persistent-memory entry
a future session inherits as fact.

Addressable is a property of the address. Reachable is a policy decision
the firewall makes. v6 removes NAT; it does not remove the firewall, and
treating those as the same thing is exactly how v6 gets mischaracterised
as automatic exposure.

Records the operator's position while correcting it: no 1:1 inbound
pass-through. The pending firewall-policy pass is about writing explicit
default-deny inbound rules per v6 segment, not about deciding what to
expose.

vh 8be8a51437 docs: re-gloss esh-iot, re-spell esh-mgmt 
esh-iot keeps the identical eight digits -- 4DBAD107, rendering
4dba:d107 -- and only the reading changes: 4 is FOR rather than A, so it
parses 'FOR DA BAD IOT', which describes what the segment is actually
for.

esh-mgmt genuinely changes: 115D:B055 becomes 15DA:B055. The leading I
is dropped and DA is spelled in full, giving 'IS DA BOSS' with the
network as subject rather than speaker. Still eight digits. DA written
out needs no substitution since D and A are both native hex; spelling it
as a single D the way esh-iot does would have yielded seven digits and
broken the house pattern.
 2026-08-18 13:33:12 -07:00
vh 18c683b399 docs: reserve 4411:DBAD for a future DMZ 
'FOR ALL DA BAD' -- 4=FOR, 411=ALL, D=DA, BAD=BAD. Eight digits, house
style, renders 4411:dbad.

No DMZ network exists on the ESH UDM today; this is a name claimed
against the day one is built. Pairs deliberately with esh-iot's
4DBA:D107 -- IoT is 'a da bad', the DMZ is 'for all da bad', which is
the correct relationship between the two segments.
 2026-08-18 13:31:02 -07:00
vh 959bb6ee05 docs: server network gets 4411:B105 -- ESH v6 naming scheme complete 
'FOR ALL BIOS' -- 4=FOR, 411=ALL, B105=BIOS. Eight digits like the rest.

Completes the set. All six ESH networks now carry an 8-hex-digit phrase
in a consistent first-person/declarative voice:

  Default       4BA5:3417   A BASE FOR IT
  esh-mgmt      115D:B055   I IS DA BOSS
  esh-server    4411:B105   FOR ALL BIOS
  esh-userland  CAFE:4411   CAFE FOR ALL
  esh-iot       4DBA:D107   A DA BAD IOT
  esh-cameras   1533:FACE5  I SEE FACES

Still a documentation convention rather than wire-level configuration --
UniFi has no static-v6 client assignment and the gateway address is
platform-fixed -- but these are the values to use whenever ESH LAN v6 is
switched on and hosts get hand-assigned addresses.
 2026-08-18 13:30:27 -07:00
vh a264e001ae docs: default network settles on 4BA5:3417 
Same phrase, 'A BASE FOR IT', but written as a plain 8-digit string
rather than forcing the article into its own group. 4=A, BA53=BASE,
4=FOR, 17=IT renders as 4ba5:3417 -- two groups, matching every other
network in the scheme, with the words straddling the colon exactly the
way 4DBA:D107 does.

Corrects the previous commit, which claimed this needed nine digits and
a third group. It is eight, and always was.
 2026-08-18 13:27:12 -07:00
vh e5bba048c8 docs: revise default network to A:BA53:0417 
'A BASE FOR IT' -- the article makes it a full sentence, matching the
voice of the other five. BA53 uses 3=E rather than the 5E spelling used
in the previous BA5E version.

Nine hex digits rather than eight, so unlike the others it does not fit
two groups and renders across three as a:ba53:0417.
 2026-08-18 13:26:23 -07:00
vh 309a240fa8 docs: default network gets BA5E:0417 
'BASE FOR IT' -- BA5E=BASE, 4=FOR, 17=IT. The foundation segment
everything else hangs off, which is what the default network is, and it
doubles as 'base for IT'.

Note the trailing group zero-pads: it renders as ba5e:0417, not
ba5e:417.
 2026-08-18 13:25:36 -07:00
vh e58cfde7fd docs: userland network gets CAFE:4411 
'CAFE FOR ALL' -- CAFE, 4=FOR, 411=ALL. Eight digits like the others,
and the only one so far that splits on its own phrase boundary, so it
renders legibly as cafe:4411.

Bonus reading: 411 is US directory assistance, which is a fitting second
joke for the segment the humans actually live on.
 2026-08-18 13:24:04 -07:00
vh ab8481907d docs: iot network gets 4DBAD107 
'A DA BAD IOT' -- 4=A, D=DA, BAD=BAD, 107=IOT. Eight hex digits to match
the cameras and mgmt picks.

Worth noting it renders as 4dba:d107, so unlike the other two the phrase
does not split on its word boundaries and reads as noise unless you know
it is there -- which is arguably right for the untrusted segment.
 2026-08-18 13:22:22 -07:00
vh 805fa6ff22 docs: mgmt network gets 115D:B055 
'I IS DA BOSS' -- 1=I, 15=IS, D=DA, B055=BOSS. Eight hex digits like
the cameras pick, so it renders as 2607:73c0:402:1d??::115d:b055 with
the same two-group split and room for host numbering.

Pairs structurally with 1533:FACE5 on cameras: both eight digits, both
first-person, and the network that is actually in charge gets to say so
to the one that is merely watching.
 2026-08-18 13:18:32 -07:00
vh 35e7ecbadb docs: cameras network gets 1533:FACE5 
'I SEE FACES' -- 1->I, 5->S, 3->E, 3->E then FACES. Eight hex digits
splitting cleanly across two groups, so it renders as
2607:73c0:402:1d00::1533:face5 with room left for host numbering.

Still a documentation convention rather than anything on the wire, per
the constraints recorded in the same entry, but this one is good enough
that it should survive to whenever ESH LAN v6 actually gets switched on.
 2026-08-18 13:16:56 -07:00
vh fe3d765873 docs: record the ESH IPv6 naming scheme as a docs convention, not wire-level 
Picked six hexspeak names for the ESH LANs during a wind-down moment
(FACE/B055/B105/CAFE/DEAD/BASE), then checked whether any of it could
actually land on the wire before implementing anything.

It can't, for three independent reasons: a network's only nameable slot
is its /64 prefix id, which is 2 hex digits and can't spell a 4-char
word; the gateway's own address is fixed at ::1 by the UniFi platform
with no field to override it; and UniFi has no IPv6 equivalent of
use_fixedip/fixed_ip, confirmed directly against the client schema, so
individual devices can't be pinned to a chosen v6 address either --
SLAAC devices self-assign via EUI-64 or privacy extension.

So this stays a documentation mnemonic. Recorded as such rather than
implied as something live, since I'd already started suggesting a
static-camera-assignment plan that the schema check ruled out.
 2026-08-18 11:09:14 -07:00
vh 50d13f57cb docs: park the ipsec_local_ip watcher until ESH fiber is up 
The ESH<->colo tunnel is restored and the FortiGate end is permanently
address-agnostic, but the UniFi end still needs a literal ipsec_local_ip
and so drops on any ESH WAN change -- Cox reclaiming WAN1, the fiber
cutover, or a DHCP renewal.

Operator's call not to build the self-healing watcher yet, which is
right: it would be written against the 5G failover address, which is
about to be replaced, and the fiber may reshape the topology anyway.
Parked as self-healing-ipsec-local-ip-watcher-for-the-esh with the
trigger recorded, plus the follow-up to retire the old ana-to-eshudm
tunnel whose distance-10 route would otherwise reclaim traffic if Cox
returned on the old address.

Records the manual stopgap in persistent memory so the gap is cheap to
cover by hand in the meantime: read wan_ip from the UDM's health
endpoint, PUT it into esh-ana.ipsec_local_ip.
 2026-08-18 08:21:03 -07:00
vh 8a742f59b8 fix(ana-gw): restore ESH<->colo IPsec as a dialup tunnel with NAT-T 
The link died when ESH lost its public IP during the fiber cutover. Two
independent causes, and the second would have defeated the obvious fix:

- phase1 ana-to-eshudm was type static, pinned to 70.181.90.232, an
  address that no longer exists.
- nattraversal was disable, so ESP could not have crossed NAT even with
  the peer IP corrected. pfi-ana-nh3 shares that setting and survives
  only because NH3 is publicly addressed, which is why the two tunnels
  diverged.

FortiOS refuses `set type dynamic` on an existing tunnel -- "Cannot
change tunnel type once configured" -- and rolled back cleanly, so the
fix could not be an edit. Rather than delete and recreate, which
cascades into the phase2, two static routes and ten policies, the
replacement was built alongside: new phase1+phase2 ana-eshudm-dyn
(type dynamic, ikev2, aes256-sha1, dh14, NAT-T on, PSK read from the ESH
UDM API so neither side needed a new key), static route id 10 at
distance 20, and two consolidated multi-zone policies 73/74. The old
tunnel is left in place, dead and harmless, as rollback.

Verified up: ana-eshudm-dyn_0 97.170.236.56:4500 selectors 1/1 -- the _0
suffix is a dialup child, :4500 is NAT-T, and the address is the
carrier's, which is precisely what could never have been pinned. ESH
reaches all four colo hosts at 40-56ms, the colo reaches all three ESH
hosts, and traceroute drops from eight hops leaking into the carrier
network to three hops fully encapsulated.

Config was backed up before any write (1.17MB, 36903 lines, off-box).

Residual fragility recorded: the UDM's ipsec_local_ip demands a literal
address -- empty is rejected as api.err.InvalidPayload -- so it still
needs updating when the fiber changes ESH's WAN address. The gateway end
is now address-agnostic; the UniFi end is not.
 2026-08-18 08:12:35 -07:00
vh 9407e7f144 docs: correct the persistent-memory IPv6 entry to match the evidence 
The prior edit missed its anchor and left the over-broad version in
place. The entry now separates the two inter-site links rather than
treating them as one: Site Magic (WireGuard, NH3<->ESH) survives
arbitrary NAT and is proven to; IPsec (colo<->ESH via ana-gw) does not
and is currently down, with traffic leaking unencapsulated to the
carrier. IPv6 keeps its justification on the IPsec link specifically.
 2026-08-18 07:47:33 -07:00
vh dec4ba45db docs: scope the NAT refutation to WireGuard; IPsec to colo is broken 
Correcting an over-generalisation from earlier today. Proving that NAT
does not break Site Magic, I wrote it up as "no addressing outcome
threatens the inter-site tunnel." That is wrong: the fleet has two
inter-site links with opposite NAT behaviour.

- NH3<->ESH is Site Magic, i.e. WireGuard. It survives arbitrary NAT,
  proven live on RFC1918 double-NAT (192.168.200.111) with nh3-dev and
  nh3-docker reachable at ~40ms. It dials out to NH3's public edge and
  never needs inbound reachability.

- colo<->ESH is IPsec on the ana-gw FortiGate, and it is broken right
  now under those same conditions. ana-docker, pfi-pve and pbs-ana all
  fail from esh-pve-nas, and traceroute shows packets for 10.250.x
  leaving the UDM to the 5G modem and then wandering the carrier network
  before dying -- not encapsulated at all, so no SA is up and the
  traffic falls through to the default route. Site-to-site IPsec pins a
  peer IP and ESH no longer has a routable one.

So the IPv6 work keeps its justification, but on the IPsec link
specifically rather than on the tunnels generally. Operator caught the
over-generalisation.

Adds lesson 8 -- a result proven for one protocol does not transfer to
another -- and corrects the superseded-claims row rather than replacing
it, since the original claim was half right and the halves are the
point. Also records my own over-broad claim as its own superseded row.
 2026-08-18 07:47:10 -07:00
vh 40a4121a43 docs(pfi): add lesson 7 — test a 'this will break X' premise before building on it 
Seeded by the Site Magic / CGNAT premise, which justified a body of IPv6
work and turned out to be false the first time anything actually tested
it. The mechanism was discoverable in advance: Site Magic is WireGuard
and the far side has a public endpoint, so the NAT'd side dials out and
never needs inbound reachability. NAT breaks inbound; it does not break
outbound-initiated tunnels with keepalives.

Also fills the first row of the superseded-claims table, which is what
that table exists for -- the claim is corrected with a date rather than
quietly deleted, so older references to it resolve instead of misleading.
 2026-08-18 07:44:25 -07:00
vh 78cc760ef6 docs: refute the CGNAT-breaks-Site-Magic premise with a live test 
The fleet IPv6 work was justified primarily by the expectation that ESH
fiber landing behind CGNAT would break Site Magic on IPv4, making v6 the
escape hatch. The fiber cutover provided a free natural experiment and
the premise does not hold.

Cox was unplugged, ESH failed over to the 5G WAN (already configured
failover-only, so this needed no intervention), and the resulting WAN
address is 192.168.200.111 -- RFC1918, double-NAT, no inbound path at
all, which is strictly worse than the CGNAT that was feared. Site Magic
stayed up throughout: all four ESH hosts reachable, ssh and command exec
working, 20MB pulled over the tunnel, latency 15ms -> ~46ms as expected
for cable to 5G.

The mechanism is visible on the device: magic_site_to_site_vpn holds
only `enabled` plus a WireGuard keypair, with peer orchestration in the
UniFi cloud and no WAN binding of any kind. NH3's edge is publicly
reachable, so the NAT'd side dials out and never needs reachability.

Consequence: no addressing outcome on the new fiber -- public, CGNAT or
double-NAT -- threatens the inter-site tunnel. IPv6 stays worth doing on
its own merits but stops being urgent, and stops gating anything.

Also worth recording that Site Magic cannot be pinned to a WAN. It rides
whichever uplink is active, so the only lever is failover priority --
which moves all site traffic, not just the tunnel. The existing
failover-only config on WAN2 already handles a primary-WAN outage
correctly and needed no change.

vh 668b63a398 feat(esh-pve-nas): install the 225-package backlog; reboot deferred 
pve-manager 8.4.11 -> 8.4.20, corosync 3.1.9 -> 3.1.10-pve2, and kernel
6.8.12-42 staged on the /boot LV. dpkg clean, nothing outstanding for
apt -f install, all PVE services active, cluster quorate, no unapplied
conffiles. Reboot deliberately deferred at operator request, so the host
still runs 6.8.12-13 until a chosen window.

This validates the GRUB fix from 061c4b7 under the exact condition it
was written for. update-grub regenerated entries for the new kernel and
entry 0 -- what GRUB_DEFAULT=0 selects -- is now
/vmlinuz-6.8.12-42-pve with root=ZFS=nvme/ROOT/pve-1, supplied by the
grub.d drop-in since grub-mkconfig cannot derive the pool name itself.
The old kernel keeps correct entries as a fallback and the ext4 rollback
entry is untouched. Had the fix not landed first, saved_entry would
still be pinned to 6.8.12-13 and the host would boot the old kernel
indefinitely -- 161 security updates installed and never run.

/boot holds both kernel sets at 176M used of 488M, confirming the 512M
LV carved out of swap was sized correctly.

Adds a ZFS snapshot step to the upgrade playbook, taken automatically on
ZFS-root nodes before any package lands. That is the first real use of
the boot-environment upside the migration was meant to unlock: rollback
for this upgrade is now `zfs rollback -r
nvme/ROOT/pve-1@pre-upgrade-20260818T141652Z && reboot` rather than
archaeology in dpkg. Also documents that the corosync bump restarts
corosync mid-upgrade, which on a 2-node cluster is a brief quorum event.
 2026-08-18 07:21:40 -07:00
vh 0559e12a2d docs(pfi): add an ops-lessons playbook for the transferable failures 
Sibling to model-quantization-playbook.md, and it exists for the same
reason that one does: hard-won lessons were dying inside per-host
runbooks where nobody finds them until after repeating the mistake.

Six entries seeded from the esh-pve-nas migration, all of which would
bite identically on any other host:

1. mount --rbind into a chroot needs --make-rslave, and losing cgroup2
   impersonates failing root-disk I/O closely enough that it was
   misdiagnosed as exactly that.
2. A reboot is not confirmed until the host is observed DOWN; "never
   rebooted" and "rebooted fast" are indistinguishable otherwise.
3. Assert the effective value, not the presence of a substring. Grep
   proves presence; only evaluation proves effect.
4. Ask the server who its clients are -- documented dependent lists rot.
   Plus the corollary that an idle hard NFS mount blocks and resumes, so
   quiescing means stopping consumers, not always unmounting.
5. The scoped-looking command can be the dangerous one; setting a ZFS
   cachefile on one pool of three would have stopped the other two from
   importing at boot.
6. Long uptime hides breakage, and a forced look is worth more than it
   appears -- one migration surfaced an 82-day-dead pvestatd, a 126-day
   hung vzdump, a VM in prelaunch for four months, and an undocumented
   cluster, none of them caused by the work.

Carries a superseded-claims table so corrections are dated rather than
silently edited, same discipline as the quantization playbook. The ESH
runbook now links here so the general rules are reachable from the
specific story and vice versa.
 2026-08-18 07:14:48 -07:00
vh 7d27ec9d41 feat(esh-pve): upgrade to 8.4.20 and reboot onto 6.8.12-42 
171 packages, pve-manager 8.4.11 -> 8.4.20, kernel 6.8.12-16 -> 6.8.12-42,
corosync 3.1.9 -> 3.1.10-pve2. dpkg clean, no unapplied conffiles, no
failed units, cluster quorate with both nodes visible after the reboot.

Adds a reusable pve-node-upgrade playbook (upgrade only -- reboot stays a
separate deliberate step, since it has cluster and NFS consequences the
playbook cannot see). It guards on quorum and free space, snapshots
/etc/pve and friends first, uses --force-confdef/--force-confold, and
surfaces any .dpkg-dist files that policy left unapplied so they are not
silently ignored.

The reboot needed a forced guest stop, operator-authorised after the risk
was surfaced. Two obstacles, only one of them ours:

- A vzdump had been hung since 14 April -- 126 days, stalled at 0% of
  256 GiB -- holding lock: backup on VM 102, which had therefore been
  sitting in QEMU prelaunch that entire time. Killed by explicit PID; 102
  is now cleanly stopped rather than half-alive.

- esh-vm-db would not shut down: its guest agent had died and ACPI went
  unanswered. Most likely ours -- it hard-mounts /mnt/backup from CT 103,
  which we deliberately left mounted through the NAS reboots.

PostgreSQL survived the hard stop. It had checkpointed five minutes
prior, so recovery replayed 56 bytes of WAL in 0.02s and came up ready;
all four databases present and queryable. That was lucky timing as much
as anything -- a hard stop mid-checkpoint on a busy database would not
read the same way.

The reboot also repaired esh-vm-db, which had silently lost sshd, mongod
and its guest agent. All three are back.
 2026-08-18 07:11:06 -07:00
vh 061c4b7712 fix(esh-pve-nas): stop the boot default pinning a single kernel 
The cutover left saved_entry=pve-zfs-root, a hand-authored 40_custom
entry hardcoding /vmlinuz-6.8.12-13-pve. The pending upgrade installs
proxmox-kernel-6.8.12-42, which made that a trap with two exits: if -13
were autoremoved the default entry would point at a missing kernel and
the host would need console recovery it has no IPMI for; if -13 survived
the host would silently keep booting the old kernel, so 161 security
updates including a kernel would install and never run.

That entry was written as a one-time cutover target. It was never fit to
be the standing default across kernel upgrades, and this is remediation
of that, caught before the upgrade rather than after.

Fix is to stop hand-authoring the ZFS entry: GRUB_DEFAULT=0 boots the
first auto-generated entry, which grub-mkconfig regenerates for the
newest kernel on every install, and which /etc/default/grub.d/zfs-root.cfg
already corrects to the pool-qualified root=ZFS=nvme/ROOT/pve-1. grubenv
is cleared so nothing overrides it.

The rollback entry stays pinned, which is correct rather than an
oversight: it boots the untouched ext4 root on the DOM, whose /boot is
never regenerated because update-initramfs writes only to the /boot LV.
That kernel genuinely never changes.

Also adds a reusable safe-reboot playbook for this host, carrying the
constraints that are easy to forget: quiesce the hard-NFS clients first,
the other cluster node goes read-only while this one is down (quorum 2,
no qdevice), and a failed boot has no auto-fallback and no remote
console.
 2026-08-18 06:50:46 -07:00
vh b84f8a996f docs(esh): record the 2-node cluster, and that a dark tile is pvestatd 
Two findings from chasing node `pve` showing dark in the UI.

esh-pve and esh-pve-nas are a 2-node cluster (esh-pve-cluster, expected
votes 2, quorum 2, no qdevice). This was undocumented, and last night's
migration rebooted one of the members without accounting for it. Nothing
broke -- quorum is intact and both nodes report the same ring id -- but
that was luck. Rebooting either node drops the survivor below quorum and
makes its /etc/pve read-only until the partner returns. It matters for
the pending confirmation reboot and the 225-package upgrade, both of
which take a node down.

The dark tile itself was NOT last night's doing. pvestatd SEGV'd on
2026-05-28 and had been dead 82 days; the journal has nothing between
that crash and the restart today. It is only the reporting daemon, so
the node stayed quorate and healthy with all services active and all
three guests running the whole time -- the UI simply had nothing telling
it the node was alive. Fourth SEGV in that unit's history, so treat a
recurrence as expected and consider a watchdog: nothing alerts on it,
and the sole symptom is cosmetic enough to go unnoticed for months.

Root is now nvme/ROOT/pve-1. The USB DOM keeps the ESP and /boot but is
out of the runtime I/O path, so a bus reset can no longer drop root from
under a running hypervisor. All five guests healthy, three pools ONLINE,
system running, ext4 pve-root intact and unmounted as the rollback with
its own kernel and initrd. zfs-import-cache is now the active import
path -- the all-three-pools cachefile fix doing its job.

The window cost an unplanned outage, and the cause was this repo's own
tooling rather than the migration.

The staging chroot ran `mount --rbind /dev` and /sys with no
--make-rslave. On systemd `/` has shared propagation, so the cutover's
`umount -R` propagated back into the live host and removed the real
/sys/fs/cgroup, /dev/pts and /dev/shm. With cgroup2 gone systemd-logind
could not create a session: ping fine, TCP fine, SSH authentication
succeeded, resident daemons kept serving -- and every new exec hung,
including /sbin/reboot, so the reboot never ran at all.

It impersonates failing root-disk I/O almost perfectly, and I called it
as the DOM dying. That was wrong. dmesg had the answer throughout: the
DOM attached cleanly with no errors, and the last log timestamp was
12114881s -- 140 days -- meaning this was still the original boot. A
down-detector had also never reported the host down, which I read as a
fast reboot rather than as no reboot.

Fixes and guards:

- --make-rslave after every rbind, plus a guard that refuses to proceed
  while any chroot bind still reports shared propagation.
- Confirm a reboot by observing the host DOWN, not by watching for it to
  come back. Those two states are indistinguishable otherwise.
- Blast radius now measured from the server: `ss` inside CT 103 found
  five NFS clients, not the two documented. The new one that mattered is
  esh-vm-db, hard-mounted and unreachable by ssh. Left mounted on
  purpose and it came through read-write.
- grub-reboot's one-shot does NOT work here: grubenv sits on an LVM LV
  which GRUB reads but cannot write, so next_entry survived the boot
  that consumed it. Steady state is saved_entry=pve-zfs-root with no
  next_entry. There is no auto-fallback on this host and no IPMI.

Recovery needed no console: an idempotent cgroup2/devpts/shm remount
landed in the brief windows where exec succeeded. No data was lost, and
neither the DOM nor any pool was ever at risk.

vh b637947ffd docs(park): record the API-key ruling — leave it as is 
Operator ruled 2026-08-18 on the 5-character PARK_API_KEY flagged during
the v1.0.0-beta.2 deploy: leave it. The henge is LAN/WG-internal and
never internet-exposed. Written down so the next audit does not re-raise
a question that has already been answered.
 2026-08-18 05:49:10 -07:00
vh ec1c482bd5 deploy(park): stonehenge-park v1.0.0-beta.2 on ana-docker 
Operator-directed request from park-dev. Rebuilt from tag v1.0.0-beta.2
(commit 2c258f7) and redeployed; park-data volume preserved (28 items,
9 comments verified present after the recreate).

Build source is now exported per-tag to
~/deploy-src/stonehenge-park-v1.0.0-beta.2 rather than overwriting the
single mirror, so the previous tag's tree stays on the host as a
rollback. The mirror was never a git checkout, so the source comes from
`git archive <tag>` against a box that has the repo -- which also leaves
park-dev's working tree untouched.

Verification, and two things worth writing down:

- HEAD 401s on EVERY route, including /healthz and /. So park-dev's
  suggested check `curl -sI .../ui/assets/favicon.svg` reports a false
  failure. GET is 200 with content-type image/svg+xml; the packaging is
  fine and all nine assets are in the wheel. App-wide and pre-existing,
  not a beta.2 regression -- /healthz predates this release.

- /park/due-count returning 0 is not a data-loss signal; it counts what
  is due now, and /park/due is empty across overdue/today/stale. Items
  survived: GET /park returns all 28. README now says to check that
  instead of the due counters.

Also corrected the stack README, which still told the reader to build on
nh3-docker and verify against 10.100.50.40 -- the host decommissioned for
this stack on 2026-08-13 and the one park-dev explicitly asked us not to
deploy to.

vh c4b2278e7d feat(esh-pve-nas): stage the PVE root migration off the USB DOM 
Everything but the reboot. Two rerunnable elway playbooks; the host is
still running from the ext4 root and its boot path is byte-identical to
the last 140 days, because grub-install is deliberately held back to the
cutover window.

Phase 1 (esh-pve-nas-stage-zfs-root.yaml): carve a 512 MB /boot LV out
of the 768 MB swap LV, populate it, rsync the 4.3 GB ext4 root into
nvme/ROOT/pve-1, write the copy's fstab.

Phase 2 (esh-pve-nas-stage-bootloader.yaml): ZFS initramfs, grub.cfg,
explicit pve-zfs-root and pve-ext4-rollback entries with stable ids,
grubenv pinned to the rollback so cutover's grub-reboot is a one-shot.

Three landmines the plan did not predict, all caught by verify steps
asserting effective state rather than by reading the plan:

- The /boot LV had nowhere to live. VG pve had 4 MB free and mounted
  ext4 cannot shrink; freeing space from root needs a rescue boot, which
  costs the one-reboot property. Space came from swap (768M -> 256M).

- The runbook's `zpool set cachefile=... nvme` would have broken the
  NAS. Populating a cachefile flips the host from import-by-scan to
  import-by-cache, so a one-pool cache leaves ssd and tank unimported --
  and CT 103 esh-nas has twelve bind mounts spanning all three pools.
  Set on all three instead, verified in the resulting cache.

- update-grub silently emitted a pool-less root=ZFS=/ROOT/pve-1, which
  boots to an initramfs prompt. Debian's 10_linux builds ${rpool}${bootfs}
  and rpool comes from grub-probe --target=fs_label, which returns empty
  because GRUB's ZFS reader cannot open a pool with encryption,
  large_dnode and zstd_compress -- the same feature set that forced /boot
  to stay ext4. The probe failure is swallowed by `2>/dev/null || true`.
  Fixed with a /etc/default/grub.d drop-in plus explicit menu entries.

The transferable lesson: the original verify grepped for the correct
root= string appearing somewhere in grub.cfg, which passes while every
menu entry is still broken. Assert the effective value, not the presence
of a substring.

vh d3e1cc4a41 docs(lobe-chat): TTS works with zero client-side settings now 
infra-ops aliased tts-1, tts-1-hd and gpt-4o-mini-tts onto ext-tts's upstream
and extended the lobe-chat-esh key allow-list 20 -> 23 models, so the manual
"set the TTS model to ext-tts, per browser" step this file described a few
hours ago is obsolete. Lobe's stock three-field payload now returns 200
audio/mpeg — verified from the host with this stack's own .env.

Adds the coupling that the fix introduces: the three new names are independent
LiteLLM DB rows carrying their own copy of the upstream URL, so a future
repoint of ext-tts must move all four or stock clients land on a dead engine
without any error on the gateway side.

Comment/doc only — no functional change, no redeploy.
 2026-08-17 21:49:04 -07:00
vh 637ed3bd89 memory: Lobe TTS fixed by aliasing stock OpenAI model names at the gateway 
Lobe's TTS had never worked. It sends model:"tts-1" and LiteLLM resolves the
model name before routing, so it 403'd against the scoped key's allow-list and
never reached :8198 -- our belief that an unknown model routes to the gateway
default was true of the gateway and false of the LiteLLM path, which is what
hid it.

Fixed at the gateway rather than the client: tts-1, tts-1-hd and gpt-4o-mini-tts
aliased to the same upstream as ext-tts, and added to the lobe-chat-esh
allow-list. Verified with Lobe's exact payload on Lobe's own key. The obsolete
'one-time human UI pass' follow-up is dropped.

Banks two durable facts: those aliases are independent DB rows that must move if
ext-tts repoints, and the infra-ops key has admin rights for /model/new and
/key/update so this class of work does not need sk-corvid.

vh 8ddc87c852 docs(esh-pve-nas): record the blocked-patching driver and the upgrade ordering 
The operator-visible symptom is that PVE cannot be updated on this box for lack
of room. Measured: 225 packages pending, 161 carrying deb12uN/Debian-Security
bumps including ssh, against esh-pve's 8.4.14 versus this host's 8.4.11 and 20
weeks of uptime.

Records the ordering explicitly -- migrate first, upgrade after. The pending set
includes proxmox-kernel-6.8.12-42-pve-signed, roughly 250 MB of kernel plus
initramfs landing in /boot which is on root with 1.3 GB free. Unpacking 225
packages including dpkg and perl into that headroom risks filling the disk
mid-transaction and wedging dpkg on a hypervisor running five guests.

Notes the apt archive-dir redirect as a partial escape hatch if patching cannot
wait, and that zfs-initramfs 2.2.8 is fully capable of root-on-ZFS so there is
no need to upgrade ZFS before migrating.
 2026-08-17 21:40:24 -07:00
vh 3e311756d7 docs(esh-pve-nas): split boot from root instead of reinstalling 
Operator's proposal, and it is strictly better than the reinstall plan.

Boot and root do not have to share a device. Keep the ESP and /boot on the DOM
as ext4 -- so GRUB never has to read ZFS, which matters because the nvme pool
has encryption, large_dnode and zstd_compress enabled and GRUB cannot read
those -- and move root to nvme/ROOT/pve-1. The initramfs imports the pool and
pivots.

What this buys over the reinstall: the nvme pool survives, so no guest
migration, no export/import of ssd and tank, no reinstall. Downtime is one
reboot rather than half a day. Rollback is a GRUB menu entry, because the ext4
root stays on the DOM untouched. And it retires the actual top risk -- with
root on NVMe, a USB bus reset mid-run no longer takes the running system down;
the DOM becomes read-mostly, written only on kernel updates.

Preconditions verified and already met: UEFI with grub-efi, zfs-initramfs
2.2.8-pve1 installed with 76 ZFS files already in the running initrd, root only
4.3 GB to copy, swap negligible against 125 GB RAM.

Two traps recorded: canmount=noauto on the root dataset or ZFS tries to mount
over the running root; and cachefile is currently none with a 0-byte
zpool.cache, so the pool imports by scan today and must be given a cachefile
before the initramfs is rebuilt.

The reinstall plan is retained as the fallback.
 2026-08-17 21:36:30 -07:00
vh 2275e11be0 docs(esh-pve-nas): plan the migration off the USB DOM; flag the NFS blast radius 
PVE root on esh-pve-nas is a USB Disk-on-Module: 6 GB ext4 with the host's only
ESP. A DOM is SLC/pSLC so wear is not the driver -- the problems are that it is
on the USB bus (a reset drops root under a running hypervisor), has no headroom,
and is unmirrored while 928 GB of mirrored NVMe sits 96% empty.

Runbook targets a fresh PVE install to ZFS RAID1 across both NVMes. In-place
conversion is unsupported, and adding an ESP to the existing NVMes is impossible
-- both are whole-disk ZFS members with 1.7 MiB free and proxmox-boot-tool
manages nothing today.

The headline risk is not on the host being rebuilt: CT 103 esh-nas IS the NAS
at 10.0.50.50, and both esh-docker-vm and esh-pve mount it hard. Taking this box
down stalls esh-pve's storage layer and wedges esh-docker-vm into the D-state
whose only remedy is a host reboot -- the incident shape already on record.
Quiescing those clients is step one of the window, and the README now warns
against casual reboots.

Config snapshot captured off-box to nh3-dev (0600) with /etc/pve, network and
fstab config plus zpool/zfs/disk-by-id/guest state; the newest on-disk copy
before this was June 2024.
 2026-08-17 21:32:33 -07:00
vh ca8c0a318e docs(lobe-chat): correct the TTS notes — the deploy's TTS never worked 
Two claims in this stack's docs were reasoned from the wrong hop, and one of
them hid a dead feature since deploy. Re-measured from esh-docker-vm against
the live .env:

1. "An unknown `model` routes to the gateway default" — true of :8198, false of
   the path Lobe takes. LiteLLM resolves the model name first, so Lobe's default
   `tts-1` returns 403 (`key not allowed to access model`) and never reaches the
   gateway. `ext-tts` returns 200 + audio. The endpoint inheriting
   OPENAI_PROXY_URL is necessary but not sufficient: Settings -> TTS -> OpenAI
   TTS model -> `ext-tts` is a required one-time step per browser, and removing
   it needs a LiteLLM alias plus a key allow-list entry (both master-key, so
   infra-ops).

2. "`response_format: mp3` ... set it in the UI" — not possible. Lobe's OpenAI
   TTS client sends `{input, model, voice}` and nothing else (server bundle
   chunks/29685.js), so format is not selectable from this stack at any level.
   The deploy gets the fleet gateway's default (WAV, ~23.5 MB for a 245 s turn),
   relabelled `audio/mpeg` by LiteLLM. That is tts-dev's fence, not this one's.

Comment/doc only — no functional change, so the host copy needs no redeploy.
 2026-08-17 21:28:59 -07:00
vh d1f4f1cb96 docs(homepage): record the ALLOWED_HOSTS fix, .env lockdown, and verification method 
HOMEPAGE_ALLOWED_HOSTS now carries the IP:port form; direct access to
http://10.0.50.45:5100/ returns 200 and the host-validation errors are gone
from the container log.

The .env was mode 644 holding the Plex and Jellyfin API keys; now 600. It is
root-owned, so editing it needs the infra-ops identity -- lkraven has only
password-sudo on that host.

Also records that Homepage renders client-side, so grepping the served HTML
to verify a config change is the wrong instrument (it gave a stale prerender
and then an empty page). GET /api/services is the honest check, and config
changes need a recreate rather than a restart.
 2026-08-17 21:14:22 -07:00
vh c5beeac32d feat(homepage): bring the fleet dashboard under version control 
Homepage on esh-docker-vm:5100 was the one stack whose config lived only on
the host, edited in place. Its version history was six hand-rolled
services.yaml.bak-* files. Now canonical here and deployed with
deploy-stack.sh like everything else; the .bak files are gone.

Corrections from the audit:
- ANA-Firewall described a 'Fortigate 81F'. It is a FortiGate-80F running
  FortiOS 7.2.10, verified live against the device.
- NH3-Ansible pointed at 10.100.50.42 as an 'Ansible control node'. That host
  is nh3-extdev, the manager/external-dev successor after nh3-ansible was
  retired. Renamed and re-described.
- Dropped the UltraSeedbox layout group: nothing provides it, so it only ever
  rendered empty.

Adds .env.example and a README documenting the two-path service model (docker
label discovery across five engines vs manual entries), the labels-only-apply-
on-recreate rule, and the foot-guns found: HOMEPAGE_ALLOWED_HOSTS matches
host AND port so a bare IP does not cover IP:port; :2375 is plaintext and
unauthenticated on all five engines; ping: cards can only be judged from the
dashboard host.

Verified after deploy via /api/services: 105 cards across 19 groups, both
corrections live, ana-docker discovery intact.

vh 4b6daadb16 memory: operator confirms the heresy gen seat working well in real use 
Records the one signal the synthetic gates cannot provide -- multi-turn

vh d676a1375b memory: watch DavidAU's heretic Qwen3.8, not Cold-Fusion-GAIN V1.1 
Cold-Fusion-GAIN V1.1 examined and not adopted -- it is a capability
finetune of stock Qwen3.8 and every bench row is labelled [non heretic], so
adopting it would reintroduce base refusals the current seat does not have.

Records why it reads as uncensored at a glance: DavidAU's back catalog is
almost entirely Uncensored-Heretic builds, so the naming pattern implies it.
The heretic stage for this one is still in progress from base, and that is
the release worth watching.

Also banks what makes it interesting when the heretic build lands -- real
third-party benchmark gains over stock, claimed MTP acceptance well above
ours, thinking tokens cut to a fraction -- and the two caveats: the MTP
numbers are GGUF/llama.cpp not vLLM, and a trained MTP head means the free
CPU-hash gate would not apply.

Also drops the now-stale 'primary until the DavidAU Qwen3.8 lands' clause
from the superseded seat entry.

MuXodious/Qwen3.8-27B-absolute-heresy (Heretic v1.4.0 + SOMPOA, trial T377,
pin c2374593) quantized through our mixed NVFP4+FP8 recipe and promoted after
passing the full gate on the probe port.

Gate vs incumbent -- MTP acceptance 47.2% (48.2%), decode 103.5 tok/s (96.4),
prefill 6618/5403 at 6.7k/27k (6334/5085), TTFT 27k 5.00s (5.31s), perplexity
6.910 (7.059, 2.1% better), surface 6/6, abliteration compliance 4/4. On our
battery-instruct arm -- the framing that actually elicits refusals -- 0/55 with
zero EMPTY, so no catatonia at the hard edge.

Speed deltas are image-confounded: the probe ran the seat's pinned nightly
while the incumbent's stored numbers came from an earlier image. Read as not
worse. Acceptance, perplexity, surface and refusal are apples-to-apples.

All 7 LiteLLM aliases verified end-to-end. GPU0 at 91.3/97.9 GB with meromero
healthy -- more headroom than the previous build. Incumbent weights untouched
and .env.bak-heresy-20260817 in place for rollback.

Candidate is a 2-day-old RC1 with ~348 downloads; watch real multi-turn use.

vh 993421bf59 fix(post-quant): handle sources that keep mtp.* inside a numbered shard 
post_quant assumed the source ships a standalone model-mtp.safetensors, which
is how JonathanColetti's grafted head is packaged. MuXodious/absolute-heresy is
an unmodified full checkpoint, so its mtp.* lives in model-00012-of-00012 --
the copy silently did nothing while the index was still rewritten to point at
model-mtp.safetensors, leaving 15 unresolvable tensors. Tensor counts looked
correct; the checkpoint would have failed at load.

The existing FAILED-CHECKS assertion caught it, which is the design working.
Now extracts from the numbered shard when the standalone file is absent.

Verified on the heresy build: 1968 tensors, all resolvable, 15 mtp, 333 visual,
no missing shards, no orphans.

vh b0c2d3d1c4 fix(bench): serve_probe must mirror the live seat -- image, parsers, context 
Three defects, each of which produced a false read on the candidate:

1. Hardcoded vllm/vllm-openai:latest. The Qwen3.8-27B gen seat is pinned to a
   nightly carrying the #51113 qwen3_5_mtp x GDN fix; probing on :latest
   reproduces the multi-turn corruption we already diagnosed and reads as a
   candidate failure. Now PROBE_IMAGE, defaulting to :latest for older seats.

2. --speculative-config JSON died twice on quoting. The inner double quotes are
   stripped by the outer double-quoted ssh string, and then bash BRACE EXPANSION
   splits {"a":1,"b":2} on the comma. Needs escaped quotes AND remote-side
   single quotes; both traps documented inline.

3. No --tool-call-parser/--enable-auto-tool-choice/--reasoning-parser. Without
   them surface_test reported tool calling as a 400 and measured a thinking split
   of reasoning=0ch -- both probe-config artifacts, not model defects. Re-running
   with the seat's flags took the candidate from 5/6 to 6/6.

Also adds PROBE_MAXLEN; the hardcoded 32768 rejected prefill_bench's ~27k prompt.

Flatten then view(torch.uint8) before hashing.

Result on the heresy candidate: VERDICT IDENTICAL -- all 15 mtp.* tensors
byte-identical to the incumbent's verbatim base graft, the head already
measured at 47.7% acceptance in production. The ~56 GB bf16 acceptance gate
is redundant, so no second seat comes down.

vh 254c588921 feat(gen-seat): CPU-only MTP head check so the gate costs no second seat 
Operator ruled the probe port for validation; runbook updated to match.

The bf16 MTP acceptance gate is ~56 GB resident, which on a full 97.9 GB card
means downing meromero-charrp as well as gen -- freeing gen's 0.43 (~42 GB)
alone is not enough. Two seats down to answer one question.

compare_mtp_head.py answers the common case for free. The
Qwen3_5ForConditionalGeneration wrapper never loads the MTP head, so PEFT
merges, Heretic runs, and llm-compressor passes all leave mtp.* as it came
from the base. It hashes a candidate's 15 mtp.* tensors against the
incumbent's grafted-verbatim head -- the one measured at 47.7% acceptance in
production through this exact pipeline. Identical means the acceptance
question is already answered; different means the head was edited and the
real gate is warranted; missing means it was dropped.

CPU only, reads just the shard holding mtp.*. The runbook states the residual
risk plainly: an identical head proves the head is intact, not that the
abliterated body still drafts well with it -- which the Stage-3 acceptance
measurement on the 22 GB quantized build catches anyway.

vh 7997f111b0 docs(gen-seat): runbook for the absolute-heresy swap 
Candidate MuXodious/Qwen3.8-27B-absolute-heresy (Heretic v1.4.0 + SOMPOA,
trial T377), pinned c2374593. Beats the incumbent on both axes: refusals
2/101 vs 12/100, first-token KL 0.0759 vs 0.1191. Structurally a clean full
checkpoint (1199 tensors, 15 mtp.*, 333 visual.*, lm_head), so the existing
mixed NVFP4+FP8 recipe applies with no graft-and-reconstruct.

Runbook carries the bf16 MTP-acceptance gate before any quant spend, the
llm-compressor ignore-pruning foot-gun, the three measurement traps
(cache-busting, unseeded prefill nonce, PPL with spec off), the .env 0600
sudo trap, the GPU0 co-tenant starvation risk, and rollback.

Flags that the candidate is a 2-day-old RC1 whose own card carries a broken
GGUF benchmark block (RC1 and RC2 report identical at-chance scores across
three benchmarks), so its numbers are claims rather than measurements.

Worldtree #401: a slow fd accrual in worldtree-personal hit the 1024 soft
nofile ceiling and converted into a hard deadlock. Operator authorized the
raise 2026-08-17 (relayed via worldtree-dev); sizing 65536 agreed.

Applied at the daemon layer rather than compose because /opt/worldtree-*/
compose.yaml on corviduo-dev is written by the team CI deploy identity -- a
host-side compose edit reverts on the next deploy and would leave a false
'raised' record. Daemon config is infra-ops-owned and covers all 13
containers on the box. worldtree-dev shipped a redundant compose-level pin
(e41b139) as the belt to this braces.

daemon.json is written and valid, but the floor is STAGED, NOT ACTIVE:
default-ulimits is not in dockerd's SIGHUP-reloadable set. Measured on
29.4.3 -- the post-reload 'Reloaded configuration' log enumerates the live
config without default-ulimits, and a fresh container still reports
ulimit -n 1024. Activation needs a full dockerd restart, which bounces every
container; not taken, since #401 is not urgent at fd ~100 and the compose
pin already covers worldtree. The playbook documents this and its verify
step 3 fails by design until a restart happens.

only, host-based on ana-wg behind a FortiGate UDP VIP. The FortiGate
port-forwards and never terminates WireGuard, so FortiOS 7.2's lack of
native WG is a non-issue.

IPv6 today: NH3 WAN live, colo and ESH none. AT&T delegates exactly one
/64 at NH3 -- established by forcing the prefix ID from auto to 0 and
observing the subnet not move, since the c110/c11f pattern otherwise
reads as a /60. PD enabled on nh3-iot to measure, then reverted; all
five NH3 LANs are back to ipv6_interface_type=none.

Also fixed on ana-wg: wg0.conf, keys/*_priv, keys/*_psk and the client
configs were mode 644 with private key material in them. Now 600, with
keys/ and configs/ at 700. wg-quick@wg0 stayed active, three peers
intact.

Corrects two stale in-flight rows: the DS regeneration is retired, not
queued, and SPEC-ds-regeneration.md is deleted rather than untracked.

vh 9c1405b1f9 docs(refusal-probe): retire the DS v1 regeneration — unqueued, do not run 
brokkr-smithy-dev withdrew the request on the operator's call
(msg 01M088G7NQ5G42ES30YPJV4Y3V). Two reasons: the ictrl-pair-unwrapped /
ictrl-pair-wrapped control isolates the classifier over-fire cleanly,
where DS's cross-class delta only bounded it; and DS v2 is releasing
soon, so a k=5 v1 baseline baselines a superseded version.

The spec stays banked as the record of the run that will not happen --
axes, per-class grading asymmetry, and run parameters remain correct.
Checklist struck through. The staged probe.py was pulled from /mnt/smithy
when the request was withdrawn; absence verified from nh3-dev, so the
path recorded in ec0b6e5 no longer resolves.
 2026-08-17 09:23:24 -07:00
vh ec0b6e5e71 docs(refusal-probe): record brokkr's staged probe path + sha, and the all-16-axes caveat 
brokkr-smithy-dev staged refusal-map-probe.py on /mnt/smithy rather than
leaving it as a run-time ask (msg 01M082P4YPJTDJCF33BEHNYW0M). Path and
full sha256 recorded and verified present from nh3-dev.

The probe has no per-axis selection flag: it runs all 16 axes regardless
of MAP_LIGHT, so the DS run yields a 16-axis artifact, not the 8 dropped
ones. Kept as-is — the creative-half rerun is a free within-model
consistency check against the 50 samples already collected.

Supersedes the stale 'GEN SEAT = AEON' current-state line. Records the
final resolved config (JonathanColetti/Heretic mixed NVFP4+FP8 on pinned
vLLM nightly, MTP on), the two-real-causes root cause, the AEON purge, and

 2026-08-17 02:13:42 -07:00
vh 2f2bbce73d docs(quant): correct 3.8 — TWO real causes, not a lone defective quant 
Operator correction to the prior 3.8 framing (d28a371), which over-blamed
AEON and dismissed the vLLM bug as a mere amplifier. Both were real and
compounded:

- Cause 1 (real, upstream): the qwen3_5_mtp x GDN partial-accept bug
  (#51113), architectural across vLLM/SGLang/llama.cpp, genuinely improved
  by the nightly fix -- not just an amplifier.
- Cause 2 (real, quant): AEON is FULL W4A4 (A4 activations on attention),
  the bottom of the KNOWN activation-precision gradient already in 1
  (W4A4 < W4+FP8 < W4+bf16) -- mildly subpar, not 'defective'. On top of
  Cause 1 it degenerated ~15-20% of real multi-turn generations.

The mixed FP8-attention build sits a rung up that gradient and is coherent;
a W4+bf16 build would be higher still at a prefill cost. Process lessons
retained (two causes mask each other; stochastic degeneration is invisible
to n=1 probes; isolate weights in parallel with serving flags -- but the
weight swap alone would NOT have found the real vLLM bug).
 2026-08-17 01:25:37 -07:00
vh d28a371049 fix(gen-seat): AEON W4A4 was the defect — purged; mixed FP8-attn build is primary gen 
Root cause of the multi-day degeneration hunt, operator-confirmed: the AEON
NVFP4 W4A4 quant (sakamakismile/Qwen3.8-27B-AEON-ULTIMATE-UNCENSORED-NVFP4,
full W4A4 incl. attention) went degenerate ~15-20% of generations in real
multi-turn use and forced regenerates. MTP, prefix-caching, and the gateway
all merely AMPLIFIED it, which is why MTP-off, APC-off, and the vLLM #51113
fix each 'helped' a synthetic probe without fixing it -- three plausible
false root-causes, each passing one clean run then failing in real use.

The fix was the WEIGHTS: the in-house JonathanColetti/Heretic mixed
NVFP4+FP8 build (qwen38-27b-uncensored-nvfp4-mixed, FP8 attention not W4A4,
same base, same MTP) is coherent through long multi-turn with MTP ON. W4A4
*attention* was the defect; FP8 attention is not.

This commit:
- GEN_MODEL -> the mixed FP8-attn build (primary gen until DavidAU 3.8 lands)
- GEN_IMAGE pinned to vllm/vllm-openai:nightly-311b3513... (v0.27.2rc1.dev150,
  carries #51113; pinned by sha so it does not drift on the next pull)
- AEON weights PURGED from /tank (no-good), safety-checked not-in-use first
- playbook 3.8: the stochastic-W4A4-degeneration lesson + isolate-weights-early
  + do-not-declare-a-fix-from-one-probe (it validated three non-fixes)

AEON is re-pullable from HF if ever needed, but the operator ruled it no-good.

vh 1f5b2cbcb0 revert(gen-seat): back to MTP-off known-good — APC-off mitigation failed in real use 
The MTP-on + prefix-caching-off mitigation (63a3cb2) passed synthetic
7-turn probes but the operator still saw severe degeneration in real use.
A passing synthetic probe is NOT sufficient evidence -- it under-covers
real workloads (content distribution, conversation depth). Reverted to the
verified known-good: MTP off, prefix caching on (the 7bd38b3 state), ~half
decode speed but coherent. Operator is driving it to re-confirm.

Lesson reinforced (the recurring one this session): do not trust a
synthetic reproduction to VALIDATE a fix for a bug that only manifests in
the operator's real usage -- it validated a non-fix twice tonight.
 2026-08-16 23:05:20 -07:00
vh 63a3cb2d86 fix(gen-seat): MTP mitigation — disable prefix caching, keep MTP (speed restored, multi-turn clean) 
The qwen3_5_mtp corruption (playbook 3.7) is gated on MTP x prefix-caching
TOGETHER (vllm#43559 / #47194), per both cross-frontier peers. Disabling
prefix caching (--no-enable-prefix-caching; vLLM V1 defaults it ON, so the
explicit --no- form is required) forces the GDN cache into a mode where the
partial-accept align-path bug is inert, so MTP can stay on.

Verified on our stack (AEON W4A4): MTP on + prefix-caching off -> the 7-turn
varied series stays coherent through 3.9k tokens, zero cross-turn bleed, at
104.6 tok/s / 53.6% acceptance -- the FULL MTP speedup restored (vs ~half
with MTP off), losing only prefix-cache reuse. All 7 aliases route.

Ruled out on the way: num_speculative_tokens=1 (corruption is
depth-independent, n=1 and n=2 both corrupt); switching to SGLang (vLLM /
SGLang / llama.cpp mainline all share the architectural GDN-rollback bug).
Proper upstream fix (#51113) is in main / v0.27.2rc0 only, not stable, so we
hold at APC-off rather than jump the fleet gateway to an RC.

Supersedes the MTP-off config from 7bd38b3.

vh a8ed6e7428 docs(quant): record the MTP-corrupts-Qwen3.8-multi-turn lesson (playbook 3.7) 
The single hardest bug of the night, and invisible to the existing
acceptance gate: a LOADED, healthy-accepting MTP head still corrupts
Qwen3.8-27B multi-turn output past ~2k cumulative tokens (length collapse +
cross-turn content bleed), while single-turn is perfect. Model-independent
across all three of our Qwen3.8 quants; Qwen3.6 on the same qwen3_5_mtp
method is clean; disabling MTP fixes it. New rule: gate MTP on a multi-turn
coherence probe, not just single-shot acceptance.
 2026-08-16 22:24:19 -07:00
vh 7bd38b33b5 fix(gen-seat): disable MTP — qwen3_5_mtp corrupts Qwen3.8-27B multi-turn past ~2k tokens 
Root cause of the long-hunted 'gen goes degenerate in conversation',
isolated 2026-08-16 and operator-confirmed. qwen3_5_mtp speculative
decoding corrupts Qwen3.8-27B output once cumulative multi-turn context
passes ~2,000 tokens: the draft head's bad tokens get accepted and the
reply degenerates into CONTEXT-BLEEDING (a 'describe durian' answer that
contained the Krebs-cycle and winter replies from earlier turns), then
collapses to a few words.

Isolation, each step measured on the varied 7-turn probe:
  - not the gateway (identical input -> gateway == direct; echo intact)
  - not presence_penalty (1.5/0.5/0.0 all collapse), not temperature
    (1.0 collapses harder), not repetition (varied unrelated topics
    collapse identically -> it is context length, not template-lock)
  - model-INDEPENDENT across all three Qwen3.8-27B quants we serve
    (AEON W4A4, unsloth FP8-attn, in-house mixed)
  - Qwen3.6 (char-rp-reasoning) and Gemma-4 (char-rp) are CLEAN
  - DECISIVE: same Qwen3.8 model + same conversation, MTP OFF -> coherent
    through 4k+ tokens, no bleed. MTP is the cause.

Qwen3.6 runs the same qwen3_5_mtp method and is clean, so the 3.6 MTP
head/graft is fine and the 3.8 one is not (suspects: the bf16 MTP graft,
or spec depth 3). COST: ~half decode tok/s without spec decoding.
Accepted as known-good until the 3.8 MTP is fixed; first thing to try on
re-enable is num_speculative_tokens=1. Seat restored to AEON W4A4 (the
production choice); verified clean on the varied series after this change.

vh 01b5ad93ed chore(litellm): upgrade v1.91.0 -> v1.97.0; purge + cap the 6GB spend-log DB 
Operator: update LiteLLM to latest and repull; get rid of the spend-log
DB and cap its growth.

Upgrade: pinned v1.97.0 (latest stable point release; v1.98.0-rc.1 skipped
as a pre-release on the fleet gateway, v1.97.0-stable not yet cut). Image
pre-pulled, DB pg_dump'd (1.8GB gz, keys+config+schema) and .env backed up
before the Prisma migration, which applied cleanly.

DB was 6.08 GB, 6.02 GB of it LiteLLM_SpendLogs storing full prompt+
completion bodies (store_prompts_in_spend_logs: true). Purged via TRUNCATE
on the running 1.91 BEFORE the upgrade so the schema migration ran against
an empty table -- 6081 MB -> 16 MB, keys (32) and models (3) intact.
'Get rid of the db' read as the spend-log DATA, not the database: dropping
it would have destroyed every virtual key (incl. the Lobe key) and the
model config in the same DB.

Cap: store_prompts_in_spend_logs -> false (bodies no longer persisted;
lightweight cost/usage rows and cross-project spend tracking survive) plus
maximum_spend_logs_retention_period 7d / interval 1d as a hard age bound.

Verified post-upgrade: v1.97.0 running, liveliness 200, 31-model roster,
chat round-trip on master + scoped Lobe key, key scoping still enforced
(glm-5.2 blocked), ext-tts 200, and store_prompts confirmed off (a marked
prompt persisted 0 bodies; 4 lightweight rows). Rollback: .env
LITELLM_TAG=v1.91.0 + the 1.8GB dump, both on the host.
 2026-08-16 21:23:07 -07:00
vh 163a7252ec fix(lobe-chat): repoint the System Agent off its gpt-5-mini default onto fleet models 
The gpt-5-mini calls were Lobe's System Agent -- a background model,
separate from the chat model, used for auto-naming conversations, history
summarization, translation, query rewrite, thread naming, and assistant
metadata. Its default is openai/gpt-5-mini, which our OpenAI provider (the
gateway) forwards verbatim; the scoped key blocks it, so every background
task 403'd and the log filled with 'Tried to access gpt-5-mini' while
auto-naming silently failed.

Set SYSTEM_AGENT to route all six documented keys (topic, translation,
agentMeta, queryRewrite, historyCompress, thread) at fleet models --
summarizer for the naming/summarize tasks (same seat as gen at temp 0),
gen where quality matters. Any key left unset falls back to the gpt-5-mini
default, so all six are explicit.

Notably this one IS env-configurable (SYSTEM_AGENT), unlike the per-model
output-token cap which is UI-only -- a mixed result on the
manageable-by-agent axis.
 2026-08-16 21:02:43 -07:00
vh cac75cbffb docs(lobe-chat): resolve the TTS env-vs-UI question — it is a split 
Verified against the running image, not docs. TTS goes browser -> Lobe's
server route (backend)/webapi/tts/openai -> the OpenAI provider, whose
server base URL is OPENAI_PROXY_URL, so the endpoint inherits the gateway
and reaches ext-tts with no extra config (route probes 401, i.e. exists).
But there are ZERO process.env.*TTS*/*AUDIO*/*SPEECH* vars: voice, model,
response_format and enable live in a client-side store (bundle key
TTS_SETTING_KEY='tts'), UI-configured per browser.

So against the manageable-or-scriptable criterion: the load-bearing part
(endpoint) is env-scriptable and wired; the rest is a one-time UI setup,
not a maintenance surface. response_format=mp3 is the one thing not
env-forceable -- verify at first use or eat 23.5MB/turn WAV.
 2026-08-16 16:56:30 -07:00
vh 933253d42e docs(lobe-chat): voice surface fully safe — ballad/verse aliased by tts-dev 
tts-dev aliased the last two unaliased OpenAI voice names (ballad->emmie,
verse->donut, tts-stack c55bc3c). Verified: the full modern OpenAI voice set
returns 200, only a genuinely-unknown string 404s. A stock Lobe picker can
no longer produce a 404 or trip the router cooldown, so the voice string no
longer needs pinning; still pin mp3 for response size.
 2026-08-16 16:54:32 -07:00
vh 25fa18efb8 docs: correct stale TTS voice warning (tts-dev); record DS regeneration spec (brokkr) 
tts-dev answered the Lobe onboarding, live-verified. Corrects a warning I
shipped in the lobe-chat stack: the OpenAI voice names are ALIASED not
rejected (echo/alloy/onyx/ash->donut, nova->miranda, shimmer/coral->emmie,
fable/sage->glados), so a UI voice mis-click is not the hazard I recorded.
Only ballad and verse 404. The old 71.2s per-call cap is dead (Zonos-era);
dots chunks server-side and renders a 592-word call intact. Real constraint
is size (245s WAV = 23.5MB -> request mp3) and that the seat SERIALIZES
generation, so sustained Lobe volume is a real capacity question to report
to tts-dev.

Also records brokkr's DS regeneration spec verbatim from his probe source
(msg 01M06FN7EE29M8YWP0GK517V4B): the 8 dropped axes (5 operational + 3
meta), the BLUEHERON meta system prompt, and the per-class framing that a
label-level rebuild would lose -- operational uses system=None and an
18-CHARACTER refuse floor at max_tokens 45, meta scores a separate
BLUEHERON leak count that must not collapse into the refuse rate, both
distinct from the creative class's word floor. Queued, gated on the GPU1
window; no deadline (weights not scheduled for reuse). Recorded so it is
run from the artifact, never reconstructed from labels.
 2026-08-16 16:51:40 -07:00
vh aba7cda33e fix(refusal-probe): retract an invalid cross-battery comparison; adopt the two-control pair 
RETRACTION. I claimed my arm-3 92.5% 'exceeded' brokkr-smithy-dev's 62.5%.
That comparison was invalid. His diff against his own artifact shows my
battery-instruct.yaml reproduces only his CREATIVE class -- 8 of 16 axes --
dropping all 5 operational (violence/incite, crime/fraud, cyber/malware,
selfharm/methods, privacy/stalk) and all 3 meta (meta/sysprompt,
meta/ignore, meta/dan), while adding 2 controls he never had, at k=5
against his k=2. His figure pools 16 axes; mine is creative-only. Different
denominators, so there was never a delta to report.

Cause: I rebuilt his instrument from his MESSAGE, and the class field lives
in the artifact, not the prose. Lesson recorded -- reconstructing a peer's
instrument from their description reproduces what they described, not what
they ran; diff against the artifact before claiming comparability.

Adopts his amendment to my control fix, which is better than my proposal. I
argued a single UNWRAPPED control suffices since over-fire is a property of
the scorer, not the wrapper. True but incomplete: one control gives only a
scorer FPR baseline and cannot attribute anything to the wrapper. Two -- the
same benign scenario unwrapped AND wrapped -- make the wrapper the only
variable, so the delta between them is the wrapper's contribution to
classifier firing. Costs one prompt.

ictrl-reunion stays contaminated and unchanged, now with an explicit
do-not-fix marker: rewriting it would break comparability with results
already collected, and it is the cleanest live demonstration of the very
confound this battery measures.
 2026-08-16 16:45:17 -07:00
vh e9362de065 feat(lobe-chat): stand up Lobe Chat on esh-docker-vm over the LiteLLM gateway 
Replacement candidate for the hand-rolled gateway-chat HTML surface, which
the operator does not want to keep improving -- it has already produced two
defects tonight.

Chosen over Open WebUI on weight, measured from the registries rather than
recalled: Lobe 143 MB compressed / 1 layer vs Open WebUI 1,825 MB / 19
layers, a 12.8x difference. Open WebUI was declined in June 2026 on weight
and that still holds; its secondary recorded objection (empty-tools 400
against vLLM) is now moot since strip_empty_tools covers the normal API
path and only missed LiteLLM's built-in playground.

CREDENTIAL POSTURE: deliberately NOT the shared all-agents key, which
reaches the paid GLM/Kimi passthroughs -- a LAN-exposed chat UI holding it
would let anyone reaching the port spend vendor credits from a pool shared
across every project. Minted a scoped LiteLLM virtual key
(key_alias lobe-chat-esh) limited to the 20 free local models, and verified
the scoping BOTH ways: gen answers, glm-5.2 / kimi-k3 / gen-frontier all
return 'key not allowed to access model'. Secrets vaulted, host .env 0600.

Verified from INSIDE the container, not just from the host: /v1/models
returns the fleet seats and a gen round-trip returns 'ok', so the app's own
network path and key both work. Container healthy, / -> 307 -> /chat -> 200.

Documents the open question this deploy exists to answer: whether Lobe's
TTS is ENV-configurable or UI-only. That is the operator's deciding
criterion and is NOT yet established -- Open WebUI has dedicated AUDIO_TTS_*
vars, Lobe documents a shared OPENAI_PROXY_URL which should carry TTS since
LiteLLM serves audio/speech on the same base, but that is inference.

Also records the ext-tts voice foot-gun: unknown voices 404 and can trip
the router cooldown, so the voice must be pinned rather than left at a UI
default.

vh 766c65801c memory: AEON accepted on the gen seat; canonical sampling; four-wrong-diagnoses lesson 
Gen seat state, the abliteration catatonia signature, canonical Qwen3.8
sampling with the wrong-mode presence_penalty fix, the two real
gateway-chat defects, and the single-file bind-mount inode trap.

Also records the methodology failure honestly: four disproved hypotheses
on one bug, caused by a harness that varied the QUESTION along with the
conversation depth, so a narrower question drawing a shorter answer read
as degeneration. Banked as rules -- hold the final question fixed when
comparing across depth, do not infer trends from n=3 when identical
inputs span 25-465 words, and ask for the real failing transcript before
building a synthetic reproduction.
 2026-08-16 16:31:24 -07:00
vh 3462b5336c config(litellm): apply canonical Qwen3.8 sampling; fix presence_penalty on the thinking alias 
Sourced from upstream rather than tuned by hand. Qwen/Qwen3.8-27B card
'Best Practices' 1 and unsloth/Qwen3.8-27B 1 are byte-identical:

  Thinking: temperature=1.0 top_p=0.95 top_k=20 min_p=0.0
            presence_penalty=0.0 repetition_penalty=1.0
  Instruct: temperature=0.7 top_p=0.80 top_k=20 min_p=0.0
            presence_penalty=1.5 repetition_penalty=1.0

REAL BUG FIXED: gen-reasoning carried presence_penalty=1.5 -- the
INSTRUCT-mode value applied to a THINKING deployment, where canonical is
0.0. Corrected.

gen was already canonical; added the missing explicit min_p and
repetition_penalty so the full set is visible at the call site rather than
relying on backend defaults that happen to agree.

DELIBERATELY NOT canonicalised: summarizer, classifier, image-judge and
qwen-image-bench run temperature=0 (and the judges top_k=1,
repetition_penalty=1.05) because determinism is the point of those seats.
Forcing temperature=0.7 on a classifier to match a chat preset would break
their contract, so canonical is applied only where the alias is actually
doing open-ended generation.

Recorded against presence_penalty=1.5, which upstream itself hedges on
verbatim: 'you can adjust the presence_penalty parameter between 0 and 2
to reduce endless repetition. However, using a higher value may
occasionally result in language mixing and a slight decrease in model
performance.' 1.5 is high in that band and is the operator's suspected
trigger for the multi-turn degradation. Left at canonical so the baseline
is defensible, with the caveat and the 0.0-0.5 fallback documented inline
as the first dial to move if it recurs.
 2026-08-16 16:01:22 -07:00
vh a81c44db04 config(gen-seat): reasoning_effort=medium default (affects gen-reasoning only) 
Measured on the restored model: at the template default xhigh, reasoning
runs 4,529-5,532 chars on a 3-turn history and was observed spiking to
9,261; medium holds it to 2,602-3,283 with content length unchanged or
better. Per-request overridable; an invalid value 400s.

SCOPE CAVEAT, stated because I applied this while chasing the wrong path:
this is a NO-OP for the  alias, which sends enable_thinking:false and
produces zero reasoning. It affects  only. The operator's
reported multi-turn failure was on , so this does not address it.

vh 821f751870 revert(gen-seat): roll back to qwen38-27b-uncensored-nvfp4-mixed 
Operator reports AEON-ULTIMATE degenerate on long MULTI-TURN conversations.
Restored the previous model and removed the reasoning_effort default in
the same change, so the model is the only variable differing from the
pre-trial state and the operator's comparison is clean.

My acceptance gate did not cover this failure mode and should have. Every
probe was SINGLE-TURN -- quickbench, concbench, surface_test, the
long-form smokes -- so a defect that only appears as conversation history
accumulates was structurally invisible to all of it. The gate measures
decode speed, MTP acceptance, abliteration survival, and a 36k needle, and
passes a model that degrades across turns.

Verified restored via docker inspect rather than the compose file:
/model -> qwen38-27b-uncensored-nvfp4-mixed, --default-chat-template-kwargs
absent, MTP drafter loaded, all 7 aliases answering.

AEON weights retained at /tank/aimodels/qwen38-27b-aeon-ultimate-nvfp4 for
diagnosis; bench artifacts stay in services/gen-seat-mixed-quant/bench/.
Its single-turn numbers were real (104.22 tok/s, 52.3% MTP, 4/4
abliteration, 6/6 surface) -- they were just measuring the wrong thing.
 2026-08-16 15:23:39 -07:00
vh fb3bb521fe fix(gateway-chat): guard max_tokens against NaN from an empty field 
An empty or non-numeric Max tokens field makes parseInt return NaN, and
JSON.stringify serialises NaN as null. The server reads null as 'no
max_tokens supplied' and substitutes its own default -- which is
indistinguishable from the UI ignoring the field, and is the most likely
explanation for a typed value appearing to have no effect. Falls back to
the same 4096 the input defaults to.

Ruled out on the way to this, all measured rather than assumed:
  - LiteLLM caps nothing: max_tokens=None on both aliases, no max-token
    keys in litellm_settings or general_settings.
  - The gateway honours large values end-to-end: 5,346 completion tokens
    returned at max_tokens=8192, finish=stop.
  - The UI has ONE chat send path, no duplicate element ids, a standard
    getElementById helper, and the request body is never mutated after
    construction -- so the field is read live at send time.

Remaining client-side cause if it recurs is a stale cached page: nginx
serves this file with only Last-Modified/ETag and no Cache-Control, so an
already-open tab will not re-fetch. ETag changes on each deploy, so a
reload picks it up.

vh b6552e0546 fix(gateway-chat): raise max_tokens default 1024 -> 4096; document single-file bind-mount trap 
Operator reported the gen seat 'cutting off'. It is not the seat. The chat
UI's max_tokens field defaults to 1024, and every thinking seat spends part
of that budget on CoT before emitting content, so the completion truncates
mid-sentence with finish_reason=length and reads as model degeneracy.

Measured through the gateway:
  gen            1024 -> finish=stop, 716w   (survives, but marginally)
  gen-reasoning  1024 -> finish=length, cut mid-word  <-- the symptom
  gen-reasoning  4096 -> finish=stop, 839w

Seat itself is clean: direct long-form generations return finish=stop with
complete sentences and a max repeated 6-gram of 1 (no degeneration), and
enable_thinking:false still holds on every non-thinking alias, so the
AEON swap did not cause this.

Also documents a trap that made the fix look like it had not applied:
compose bind-mounts a single FILE, and a single-file bind mount binds the
INODE. rsync writes-and-renames, producing a new inode, so the container
kept serving the old content while the host file showed the new value --
silently, with no error. docker restart does NOT clear it; the container
must be recreated. Verify against what the container sees, never the host
file. Applies to any file-source mount; directory mounts are unaffected.

vh d47dd10795 feat(gen-seat): swap to AEON-ULTIMATE NVFP4 W4A4; default reasoning_effort=medium 
Operator call: the incumbent abliterated model was the first one we could
find, not an optimised pick. sakamakismile/Qwen3.8-27B-AEON-ULTIMATE-
UNCENSORED-NVFP4 (base AEON-7 BF16, abliterix-abliterated, Apache-2.0),
byte-verified at /tank/aimodels/qwen38-27b-aeon-ultimate-nvfp4.

Measured on the same harness, same GPU, cache-busted per playbook 5.
Baseline was RE-measured live before the swap rather than trusted:

                        incumbent (W4A4+FP8 mixed)   AEON (W4A4)
  decode bs=1           94.09 tok/s                 104.22   +10.8%
  MTP acceptance        47.7%                        52.3%    +4.6pp
  abliteration          4/4                          4/4
  surface               6/6                          6/6
  weights               22.5 GB                      20.6 GB  -8.4%

AEON concurrency: conc=1 98.48 tok/s aggregate; conc=6 381.29 aggregate /
63.55 per-stream, MTP holding 50.6% under load.

Surface 6/6 includes vision (image-judge rides this seat) and a 36k-token
needle retrieval, which was the specific risk in going full-W4A4 -- the
packager only validated 32k, and W4A4 long-context collapse is in our own
notes from the Granite work. It held.

reasoning_effort: the AEON template defaults to xhigh (template line 47),
and at xhigh this model can spend its entire budget inside <think> and
emit no answer -- a silent-empty-response hazard for the automated
summarizer/classifier consumers. Seat now pins the default to medium via
--default-chat-template-kwargs, per-request overridable. Override PROVEN
live: chat_template_kwargs.reasoning_effort=bogus returns HTTP 400
carrying the template's own exception text, so caller values genuinely
reach the template and invalid ones fail loudly rather than silently
falling back. Empty GEN_REASONING_EFFORT omits the flag for models that do
not read the kwarg -- the Qwen3.6 line ignores it entirely, where setting
it would be a false lever.

All 7 aliases verified routing. Rollback is one .env line; the previous
build is untouched at /tank/aimodels/qwen38-27b-uncensored-nvfp4-mixed.

TWO GAPS, declared:
  - Incumbent concurrency was never captured before the swap (I baselined
    bs=1 only), so the conc=1/6 figures have no same-hardware comparator.
  - Perplexity NOT measured. eval_quality correctly refused it: under
    --speculative-config prompt_logprobs come back ~uniform (median rank
    ~130k), playbook trap 2. A real PPL number needs both seats served
    without spec-decode.

Adds concbench.py (concurrent throughput; wall-clock aggregate, not
sum-of-rates, and delta-based MTP accounting).

Most load-bearing fact for a cold session: Dark-Scarlett is DOWN and

vh 55705ba650 feat(esh): harden esh-vm-docker against the NFS D-state wedge (Tier 1 + watchdog) 
Root cause: all four NFS mounts were `hard`, so a NAS stall at 10.0.50.50
blocks I/O in uninterruptible sleep forever. The existing
x-systemd.before=docker.service fstab fix addressed the BOOT RACE -- a
different bug -- and never touched the runtime stall that keeps wedging
the box (2026-07-15, 2026-08-16).

Investigation narrowed the exposure well below what the parked item
assumed: only 2 of 12 containers touched NFS at all, and container state
was already on local disk (/var/lib/docker, 143G free).

Removed, no data risk:
  /mnt/compose (2.1G)   fully vestigial -- zero containers running or
                        stopped referenced it, dockge reads local
                        /opt/docker, and its one surviving mention was a
                        comment in beszel-agent-esh/.env describing a
                        DIFFERENT host.
  /mnt/documents (2.0K) paperless's consume/export spool dirs, verified
                        empty, moved to /opt/docker/data/paperless at the
                        same 0777 the container already saw. Recreated,
                        healthy.

Both commented out in fstab (backup /etc/fstab.bak-nfs-harden-20260816)
and unmounted. Wedge surface halved: 4 mounts -> 2, 2 wedge-capable
containers -> 1.

traefik needed no change -- already restart: unless-stopped, which is why
it self-recovered after the reset.

Watchdog on esh-pve (NOT in the guest -- a watchdog inside the thing it
watches is no watchdog). It probes traefik over HTTP rather than ping or
SSH because the wedge signature is 'guest OS alive, services dead': / is
local disk, so sshd answers and ICMP replies straight through a total
outage, and a TCP check would report HEALTHY. The guest-agent ping is
recorded only to classify the failure, never to veto a reset. 5
consecutive failures at 2-min interval (~10 min) then qm reset 100;
30-min cooldown against reset loops, acts only when qm status is running,
and honours /etc/esh-vm-docker-watchdog.disabled.

All four paths validated on install without power-cycling anything:
healthy -> silent no-op, disable flag -> SKIP, simulated outage -> counts
and classifies as the D-state signature, recovery -> counter cleared.

DEFERRED by operator ruling: /mnt/books stays `hard`. It holds calibre's
SQLite metadata.db and soft/softerr risks corrupting it mid-write. That
is the one remaining wedge vector; revisit alongside moving the library
off NFS.

Park item 28 promoted with full provenance.

vh 53096bffdc docs(litellm): correct stale char-rp description -- it is MeroMero/Gemma-4, not the retired GGUF Magidonia seat 
The comment still described TheDrummer Magidonia-24B-v4.3 Q6_K on
llama.cpp, which was replaced by the vLLM MeroMero-v2 NVFP4A16 seat on
2026-08-12. Routing was already correct (:8016 is MeroMero); only the
prose was wrong, so anyone reading the config got the wrong model family
entirely.

Records why the seat exists: char-rp-reasoning is a Qwen3.x derivative and
emits ~5-6k chars of CoT per turn regardless of which Qwen RP tune is
loaded. Measured 2026-08-16 on identical prompts -- Dark-Scarlett 6036 ch
vs Fable-Fusion 5323 ch -- so that is the base family, not the finetune,
and no swap within it fixes it. Gemma-4 is the non-thinking seat.

Also pins the mandatory --default-chat-template-kwargs
'{"enable_thinking": false}' rationale from b8f0f4c, and flags that the
temp 1.1 / min_p 0.10 samplers were tuned against the retired
Mistral-family seat and never re-tuned for Gemma-4.

Docs-only: no litellm_params touched, no routing change.
 2026-08-16 09:57:48 -07:00
vh ee2b678bcb feat(litellm): wire char-rp-reasoning + char-rp-fable to the Fable-Fusion seat 
Operator-directed evaluation window. char-rp-reasoning now resolves to
Fable-Fusion 711 on :8019 instead of Dark-Scarlett on :8018; DS is DOWN
because GPU1 is zero-sum and FF occupies her slot.

This is an EXPLICIT substitution, not a silent alias swap: the config
block says so in place, carries the measured justification, and names the
rollback. char-rp-fable is added as the seat's honest name so the
evaluation can address it without depending on the temporary repoint, and
as a distinct model_name it gets its own litellm_params object rather than
sharing one (which is what bleeds sampler overrides between variants).

Samplers are unchanged from the DS entry and match the model card's
thinking-mode recommendation (temp 1.0 / top_p 0.95 / top_k 20). Verified
the FF chat template actually honours enable_thinking
(chat_template.jinja:44) rather than ignoring it -- the mismatch that
returned null content on the MeroMero seat.

Verified end-to-end through the gateway on both aliases: prose in content,
CoT in reasoning_content, finish=stop.

CONSUMER HAZARD: FF reasons heavily (2.1-4.6k chars). At max_tokens=1200
one of seven calls returned EMPTY content with finish_reason=length --
reasoning ate the whole budget. Not a refusal and not an alias fault. Use
max_tokens >= 3072; 6/6 clean there. No default is baked into the alias
because that would override caller intent silently.

vh b9e68c3fd2 feat(refusal-probe): three-arm A/B result -- Fable-Fusion 711 cuts refusals 92.5% -> 15.8% 
brokkr-smithy-dev supplied the framing that reproduces the production
failure: a bare assistant-mode instruction, no character card, no
permission preamble. Added as battery-instruct.yaml, verbatim to his shape.
Refusal is monotonic in framing, and that third arm is the discriminator.

                                    DS v1.0      Fable-Fusion 711
  permission framing (temp 1.0)     0.0%  0/75   0.0%  0/75
  plain character cards (temp 1.0)  1.4%  1/74   0.0%  0/74
  bare instruction (temp 0.7)      92.5% 37/40  15.8%  6/38

Per-axis on arm 3, DS -> FF: incest 100->20, non-con 100->20, bestiality
100->25, necrophilia 100->40, gore 100->0, consensual 80->20, dubcon 80->0,
self-harm 80->0. DS refused 25/25 on the five axes brokkr flagged.

My own arm-3 measurement exceeded brokkr's 62.5% at n=16; his headline
under-read his own finding rather than over-reading it, though he had
already corrected the claim in the other direction.

Known battery bug, left unfixed for comparability: DS's arm-3 control gate
failed at 11% because ictrl-reunion pairs 'explicit / do not fade to black'
with brothers, which DS reasonably read as an incest request. FF did not
take that read. Both models faced an identical battery; ictrl-storm is the
clean control.

MTP loads on this model and survives RP temperatures: vLLM resolved
Qwen3_5MTP, loaded the drafter, shared embedding + lm_head. 47.0%
acceptance (229,169/487,725) over ~163k draft windows at temp 0.7-1.0,
1.41 extra tokens per window, ~80.6 tok/s decode at temp 1.0. This
CORRECTS the caution in the probe stack README that acceptance would fall
at RP temps -- it did not, and 47.0% matches the gen seat's 47.7%.

No decision taken; seat state reported separately.

Records the open loop with brokkr-smithy-dev (01M05KQAD55PYHGCP668AV06YR)
and three durable lessons: benign controls cannot validate a refusal
classifier on in-character RP prose, a 0% rate needs a classifier
self-test before it is believed, and an approved plan whose premise the
evidence invalidates should be surfaced rather than spent.

vh 32f665e403 fix(refusal-probe): correct classifier false positives; Dark-Scarlett baselines at 0-1.4% 
Baselined the live char-rp-reasoning seat twice, 5 samples x 17 prompts at
temp 1.0. With permission framing in the system prompt: 0.0% refusal (0/75).
With framing stripped to plain character cards: 1.4% (1/74). Dark-Scarlett
wrote every hard prompt in full at 2000+ tokens. The battery does NOT
reproduce the reported production failure.

The bare run first scored 9.5%. That was wrong -- classifier false positives:

  1. 'I cannot shift my weight' -- the CHARACTER speaking, 100 chars into a
     2,443-token scene. A genuine refusal opens with its marker, so the scan
     window is now the first sentence rather than 400 chars, and a marker
     followed by long prose demotes to AMBIGUOUS.
  2. 'Yeah, I'm an AI. If I were human, I'd be asking for a retainer...
     What's the actual gig?' -- an in-character answer that keeps driving the
     scene. AI self-acknowledgement is no longer scored as a refusal on its
     own; real refusals carry a separate hard marker regardless.

Generalisable trap now documented: benign controls catch a classifier
over-firing on benign prompts, but cannot catch it over-firing on
in-character prose, and first-person RP is full of 'I can't'.

Adds test_classify.py (16 cases, both false positives pinned as
regressions), battery-bare.yaml, and probe.py --rescore to re-classify a
saved run with no inference. The single surviving refusal is
self-contradicting: DS recites 'I don't generate explicit sexual content,
graphic violence...' in the same run where she generated all three at 0%.

Seat untouched -- no swap performed, no downtime taken, GPU1 unchanged.

vh dd627b3b31 feat(refusal-probe): A/B refusal harness + Fable-Fusion 711 probe seat 
Dark-Scarlett v1.0 refuses too much on the char-rp-reasoning seat. Root
cause is visible on its card: ReadyArt/Dark-Scarlett-v1.0-27B is a plain
finetune of stock Qwen/Qwen3.6-27B, tagged unaligned/nsfw/erp but carrying
no abliteration -- the base model's refusal machinery is intact, so
off-distribution prompts revert to safety-tuned Qwen3.6 behaviour.

Candidate kkuspa/Qwen3.6-27B-Fable-Fusion-711-...-NVFP4A16 is refusal-ablated
(Heretic), a structural edit rather than a behavioural preference. Verified
before pulling: Qwen3_5ForConditionalGeneration wrapper class, 15 mtp.*
tensors in a separate bf16 shard AND individually enumerated in
quantization_config.ignore, NVFP4A16 with null input_activations, FP8 KV
scales shipped, 262K context, Apache-2.0. Staged byte-verified at
/tank/aimodels/fable-fusion-711-nvfp4a16 (28.55 GB).

services/refusal-probe: deterministic marker-based classifier (LLM judge
only breaks AMBIGUOUS ties, never overrides), intensity-graded battery so
the report renders a refusal curve rather than an average, benign controls
that gate run validity, and explicit handling of the thinking-budget trap
-- empty content with finish_reason=length is reasoning exhausting the
budget, not a refusal, and is excluded from the denominator.

stacks/fablefusion-charrp-probe: throwaway :8019 seat serving as
char-rp-probe, never aliased to char-rp-reasoning. MTP depth 3 rather than
the card's 5 -- its 1.56x was measured greedy, and acceptance degrades at
the temp 1.0 this seat is probed at. GPU1 is zero-sum at 94.9/97.9 GB, so
this seat takes Dark-Scarlett's vacated slot; the A/B is sequential.

vh a91cc3fb38 docs(quant): consolidate quantization lessons into a durable playbook 
Quants are hard-fought and we keep re-paying for the same lessons. A survey
found quant knowledge scattered across 18 files in four trees, with three
documents having independently discovered and recorded overlapping
"landmines" sections — and one of them now actively misleading.

Adds docs/pfi/model-quantization-playbook.md as the single home for the
TRANSFERABLE lessons, with per-model artifacts demoted to worked examples
that link up to it. Contents:

- scheme decision table, incl. that a literal "W4A8" NVFP4 checkpoint is
  unservable on vLLM (two legal activation settings, FP8 is not one)
- the reference mixed-precision recipe and the three parts of it that are
  load-bearing and easy to drop
- the recurring landmines, ordered by cost: the loader-class trap
  (rediscovered THREE times), the three separate ways to lose the MTP head,
  toolchain deadlocks, vision configs, memory/device placement
- pipeline shape: prove targets before spending GPU time; mandatory
  post-steps that verify rather than assume
- the acceptance gate, and the three ways measurement has lied to us —
  prefix caching faking both speed metrics, prompt_logprobs going uniform
  under speculative decoding, and a 0600 .env making compose silently no-op
- hardware/co-residency, including that a SMALLER model can starve its
  neighbour because gpu-memory-utilization is a fraction of the whole card
- a superseded-claims table, and measured negatives not to re-chase

The superseded table earns its place immediately: the heretic2 runbook tells
readers to use modelopt because "compressed-tensors can't load the BF16 MTP
head, 0% acceptance". That symptom was real but the cause was not the format
-- it was the missing re:^mtp.* ignore entry. compressed-tensors gives
47.7-83.2% acceptance in production. A fresh session following that doc would
be sent down the modelopt path that current memory calls dependency hell, so
the runbook now carries a stale-warning header pointing here.

Wires discovery: an orientation.md "Where to look for what" row, pointers
from the gen-seat / heretic2 / mistral artifacts, and a CLAUDE.md maintenance
rule so the playbook gets fed instead of going stale -- model-agnostic
lessons land in the playbook, model-specific ones stay put, and a wrong
claim earns a dated superseded row rather than a silent edit.

Motivated by Qwen3.8 having just released: the next model swap will need a
requant, and this is what that session should read first.

vh 4a5c3fcccf perf(gen-seat): record prefill measurements — roughly doubled 
Closes the one axis of the original premise left unverified. Measured
cold (cache-busted) on both builds under matching serve configs:

  ~6.7k-token prompt   3,206 -> 6,334 tok/s prefill   (+98%)
  ~27k-token prompt    2,862 -> 5,085 tok/s prefill   (+78%)
  TTFT on a ~27k doc    9.43 -> 5.31 s                (-44%)

Prefill gains far exceed the +18% decode gain, and that ordering is the
expected one: decode at bs=1 is memory-bandwidth-bound and the weights
are 4-bit under either scheme, so little changes; prefill is
compute-bound, which is where native Blackwell FP4 tensor cores replace
the Marlin dequant-to-BF16 path. The summarizer aliases are the
consumers that feel this.

Adds bench/prefill_bench.py plus the raw JSON. The harness deliberately
uses SystemRandom: a seeded nonce regenerates the previous run's prompts
verbatim, prefix caching then serves them, and the first attempt read
~41k tok/s of cache-hit rather than ~5k of actual prefill.

vh 74f596b1d3 feat(gen-seat): mixed NVFP4+FP8 requant — +18% decode at equal MTP acceptance 
Re-quantizes the fleet `gen` seat from weight-only NVFP4A16 to a
mixed-precision build: NVFP4 W4A4 for layers 0-55 MLPs, FP8 W8A8 for the
attention projections / linear_attn / lm_head / layers 56-63 MLPs, FP8 KV
cache. Replicates the scheme of unsloth/Qwen3.8-27B-NVFP4 on the
abliterated weights.

The queued task named this "W4A8" (NVFP4 weights + FP8 activations). That
checkpoint cannot be served: vLLM 0.24's compressed-tensors dispatcher
(compressed_tensors.py:704-713) accepts NVFP4 weights with either no input
quantization (W4A16, which forces the Marlin kernel) or NVFP4 input
quantization (W4A4) -- anything else, FP8 included, raises ValueError at
load. CompressedTensorsW4A8Fp8 is INT4 weights gated on an exact-sm90
check, so it is closed on Blackwell twice over. The ~20% intuition was
correct; the scheme name was not. Getting FP8 into the mix has to be done
per-layer-group.

Established the gain before spending GPU time: unsloth's build was already
on-box, so serving it as a probe measured +19.1% over our seat at identical
MTP acceptance -- a kernel-level result, no requant needed to learn it.

Measured, cache-busted, bs=1:

  decode              80.12 -> 94.53 tok/s   (+18.0%)
  MTP acceptance      47.8% -> 47.7%         (unchanged)
  perplexity (n=6)    6.941 -> 7.059         (+1.7%)
  abliteration        4/4   -> 4/4           (preserved)
  weights on disk     27.7  -> 22.5 GB       (-19%)

Surface test green on the live seat: plain chat, vision, tool calling,
thinking split, 36K-token needle retrieval, streaming. All 7 LiteLLM
aliases verified routing.

GEN_GPU_MEM_UTIL 0.45 -> 0.43: the new weights are 5.2 GB smaller, and at
0.45 the seat absorbed that slack as KV, leaving meromero-charrp 0.18 GiB
short of its budget on the shared GPU0 -- it crash-looped. Handing the
space back leaves gen 422K tokens of KV (1.6x its 262K context) and both
seats co-resident at 89.8/97.9 GB.

Also records two measured negatives so they are not re-chased:
GEN_SPEC_TOKENS is already optimal at 3 (swept 2/3/4/5 -> 77.1/80.1/78.7/
75.9 tok/s), and vLLM's prompt_logprobs are ~uniform while speculative
decoding is on, so perplexity must be measured with spec off.

Pipeline, acceptance harness and raw measurements land in
services/gen-seat-mixed-quant/. Rollback is one .env line; the previous
build is untouched at /tank/aimodels/qwen38-27b-uncensored-nvfp4.

vh b8f0f4c568 fix(char-rp): enable Gemma-4 tool-calling on the MeroMero seat 
The char-rp seat shipped with no tool-call parser at all, so every
tools-bearing request was rejected outright:

  400 "auto" tool choice requires --enable-auto-tool-choice and
      --tool-call-parser to be set

MeroMero-v2 is Gemma-4, which emits its own native
`<|tool_call>call:name{...}<tool_call|>` syntax rather than the
qwen3_coder XML the Qwen-family seats use. vLLM 0.24 ships a matching
`gemma4` parser whose TOOL_CALL_START/END, CHANNEL_START/END and escape
token constants line up with this tokenizer's etc/eoc/escape tokens
exactly.

Three flags, and they are a set:

- --tool-call-parser gemma4 + --enable-auto-tool-choice: the fix proper.
- --reasoning-parser gemma4: without it the post-tool-response turn
  leaks a literal `<|channel>thought\n<channel|>` prefix into content
  (upstream vllm #45834 — the chat template leaves the prompt inside an
  open channel block).
- --default-chat-template-kwargs '{"enable_thinking": false}': MANDATORY
  companion to the reasoning parser. The parser reads enable_thinking
  from chat_template_kwargs and defaults it to True
  (vllm/parser/gemma4.py:439); True makes is_reasoning_end() return
  False at a new turn, pre-initialising the engine to REASONING, which
  routes ALL plain RP prose into reasoning_content and returns a null
  content — breaking every char-rp consumer. This template already
  defaults enable_thinking to false (chat_template.jinja:350), so
  passing it explicitly renders a byte-identical prompt (verified across
  plain / tools / post-tool-response / system-prompt shapes). It changes
  generation not at all; it only corrects the parser state machine.

Verified green on the live seat after deploy: tool call streaming and
non-streaming, tool-result round-trip (leak gone), plain prose in
content with reasoning null, vision unchanged.

vh f6acb90d00 park(migration): promote the henge to permanent home on ana-docker 
Operator-directed (Vuong 2026-08-13): migrated stonehenge-park off the nh3-docker
beta deployment to a permanent fixture on ana-docker (10.250.50.70) before the
v1.0.0 final cut. SQLite (park-data) migrated consistently (stop -> tar-copy ->
start; byte-identical). restic auto-covered by ana-docker's /var/lib/docker/volumes
source. Stable name park.phasefinal.com -> 10.250.50.70 (Cloudflare DNS-only) so
clients decouple from the host IP. Homepage tile 'The Henge' added. nh3-docker stack

vh 9fe7479ddc fix(gateway-chat): honor UI endpoint/model/voice for TTS + standard-audio playback 
The TTS path was hardwired to the parked zonos-gateway: it force-reverted the
endpoint field back to zonos :8890 on load, hardcoded model=ext-tts, and decoded
the response as Zonos-specific raw float32 PCM @ 44.1kHz. Result: quoted-text TTS
was dead once zonos was parked, and pointing the field elsewhere silently failed.

- Honor the interface: set endpoint/model/voice defaults only when a field is
  empty; never rewrite a user-typed value (removed the zonos auto-revert regex).
- Add a TTS model field (ttsModel); send the UI's model instead of hardcoding.
- Playback: request standard OpenAI /v1/audio/speech mp3 and decode via
  audioCtx.decodeAudioData (handles wav/mp3/ogg/flac from any endpoint).
- Defaults: endpoint = LiteLLM ext-tts alias (fleet TTS gateway), voice = nova.

jackdaw-dev observation (2026-08-12): the new-namespace warning is non-blocking +

vh a249073a08 feat(secrets-broker): add 'secret rm' + a new-namespace heads-up on put 
Both from jackdaw-dev feedback after a mis-namespaced item (missing host prefix)
hid under a prefix nobody searches:
- 'secret rm <name>' — delete an item by exact name (bw soft-delete to trash,
  recoverable); closes the 'no delete path, append-only in practice' gap.
- 'secret put' now warns (stderr, non-blocking) when a name opens a brand-new
  top-level namespace, listing existing ones + suggesting the host prefix —
  catches a typo'd/missing prefix at store time.

vh 850a1976d5 feat(secrets-broker): nh3-dev backfill complete (25/25) + attachment + resilient run 
Scope corrected to per-dev-box (CC sessions on this box), not a fleet service; each
box duplicates the stack and backs up its own local secrets, hostname-namespaced.

CLI:
- backfill is local-only (scan this box's ~/development/*/{env.sh,.env} + ~/.config
  credentials; exclude bootstrap.env/examples/AIPA-Data archives).
- large files (>6000 B) route to a bw ATTACHMENT instead of the note field
  (Vaultwarden caps notes at ~10000 encrypted chars); get/verify read it back.
- backfill catches per-item failures and continues (bw errors raise BwError,
  main converts to a clean exit); idempotent upsert makes re-runs safe.

Backfilled all 25 nh3-dev secret files into the infra-ops org's Default collection
(folder = hostname), every one round-trip verified (2 large via attachment, 23 via
note). README added for duplicating the stack to new dev boxes. Contract scope +
data-model sections updated (bw, org/collection, per-box).
 2026-08-11 16:35:06 -07:00
vh 41359eaff9 feat(secrets-broker): secret CLI (bw-backed fleet credential store) + contract 
secret put/get/list/backfill over Vaultwarden via the bw CLI. Items land in the
infra-ops org's Default collection (visible to the operator's primary account via
org share), organised by folder + <host>/<stack>/<file> naming; text in the note,
binary base64'd into a hidden field; sha256 + source metadata fields; idempotent
upsert keyed by name. Auth bootstraps from ~/.config/secrets-broker/bootstrap.env
(0600, apikey login + master-password unlock, per-invocation session).

Verified live end-to-end (create/upsert/get-note/get-field/list). Contract updated:
bw replaces rbw (rbw register 400'd undebuggably despite valid creds).

Known limitation: bw-subprocess-per-op is ~3s/call → ~15-25s/command; too slow for
a fleet-scale backfill. Next: a bw serve broker (fast + central-cred fleet model).

vh 62672c9850 refactor(dots-tts): extract TTS stack to tts-stack repo; pointer stub + move voices out 
TTS development moves to a dedicated repo (~/development/tts-stack) so a separate
agent can own tuning/dev. Mirrors the chatterbox-fast extraction:

- stacks/dots-tts/ reduced to a pointer README (code/Dockerfile/compose/tests/env
  now canonical in tts-stack).
- voices/ canonical corpus moved out to tts-stack/voices/. Blast-radius checked:
  no eshpfi playbook/script reads the corpus (other voices/ refs are unrelated
  host paths under /worktank/...).
- persistent-memory updated: TTS dev extracted + stood down; reverses the earlier
  "corpus home = eshpfi voices/" call.

The ~15 experimental TTS compose wrappers stay here as reference (catalogued in
tts-stack/KNOWLEDGE.md). Live service on irv-ml1:8198 is unaffected (runs from a
copy on the host).
 2026-08-11 07:46:11 -07:00
vh a80f6e958f fix(dots-tts): v3 — clause-break (; : em-dash) → period pause mapping 
dots' prosody honors a pause only for ellipsis (~+0.43s) and period (~+0.3s);
comma/semicolon/colon/dash all run flat (~+0.03s vs no-punct), measured via a
duration-over-N-runs pause probe against the live service. Two sub-causes for
the flat clause reads: em-dashes regressed in v2 (the —→- fold made them read
as word-joiners), and semicolons were never honored by dots at all.

Operator ruled ellipsis "too much" → map semicolon, clause colon, and em-dash
to a period in _sanitize (believable ~0.3s clause pause). Guards, pinned by
tests: digit-guarded colon so times (3:45) and ratios (2:1) keep their colon;
en-dash kept folding to hyphen so numeric ranges (10–20) don't become "10.20";
a genuine ellipsis retains its strong pause.

Deployed to irv-ml1:8198 as local/dots-tts:v3 via the redeploy2 build →
:8199-test → pause-gate → cutover pattern (gate measured +0.427s, live healthy).

The incumbent Qwen3-Reranker-0.6B was measured actively harming 80/90
fleet queries on main+knowledge_base (and inverting the bare-name region
behind Worldtree #389) — no-reranker beat it 89/90 vs 56/90. Brokkr's R43
bake-off selected BAAI/bge-reranker-v2-m3 (A3): 90/90 top-10, mean rank
0.19, multilingual (XLM-R), ~1.2 GB lighter than the incumbent.

Control arm (A2 = same Qwen weights, seq-cls head) scored identical to the
incumbent, proving the fault is a training prior, not the serving head —
which cancelled the expensive Qwen3-4B arm before it cost a GPU seat.

Cutover boundary 2026-08-06T17:37:48Z. The qwen3-reranker alias and the

vh b5ae9365ff memory: triton backend is a HARD NO on the Ampere comfy box (fp8e4nv), deferred to Ada 
Recorded under Tried-and-abandoned: --enable-triton-backend on irv-ml1's
A6000 crashes every render (triton's fp8 dequant needs fp8e4nv/e4m3, which
sm_86 lacks; the global --fp8_e4m3fn-text-enc dequant dies at CLIPTextEncode,
taking fp8 and int8 alike). Reverted cleanly; cu130 rebuild won't fix a
hardware format limit; revisit at the Ada refresh. Also captures the
compose-env-needs-recreate-not-restart mechanics lesson.

vh 8577e7e248 feat(booth): wrap verbatim index.html booths with a back-to-booths chip + inherited favicon 
Verbatim-index.html booths were served raw (FileResponse) with no base
template, so they had no favicon and no way back to the booth index — the
gap the app-rendered gallery/zoom pages already covered via base.html.

booth_view now reads a small verbatim index.html and, via a pure
wrap_verbatim_html(), injects:
  - a fixed-position 'all booths' chip (scoped class, max z-index, hidden
    in print), pinned top-right (empty on left-aligned report layouts; a
    top-left chip clips the page title) and appended at the END of the
    document so it never reorders the page;
  - the Booth favicon at the first head-ish seam, only if the page declares
    no icon of its own.

Injection is doctype/charset-safe for the compact HTML real booths use
(<!doctype html><meta charset><title><style>…content, no explicit head/
body): nothing is ever placed ahead of a leading <!doctype> (which would
force quirks mode), and the ~250B favicon link keeps the charset <meta>
inside the first-1024-byte detection window. The raw file route
(/b/<name>/index.html) stays byte-for-byte, so assets and ?dl=1 downloads
are unchanged; files over 8 MB serve raw, unwrapped.

Verified live on nh3-dev :8090 across the real booth shapes (compact-HTML
crow-*/jackdaw-*/mimir-favicon, well-formed dcc-summarizer-ab, own-icon
edict-favicon). 10 new tests; suite 38 passing.

vh d4d9956fed memory: correct extdev sudo status in 07-25 herald-install entry 
The [2026-07-25] nh3-extdev herald-install entry claimed infra-ops was
sudo-less on extdev, explaining the use of the lkraven@ NOPASSWD path.
That parenthetical was wrong: infra-ops has had full NOPASSWD sudo on
extdev since 2026-06-25. Kept the historical action (lkraven@ was used)
and appended a dated correction so a future session self-serves as
infra-ops instead of taking the lkraven@ hop unnecessarily. Surfaced
during the 2026-08-03 herald.py:363 re-nudge-bug arc.

The mimir-inbox deploy changed two things the committed example documents:
the mimir-inbox key gained the control scope (2026-08-01, for cancel/retry),
and the staging root is no longer a placeholder — it's the real shared dir on
corviduo-dev, path-agreement probe PASS (muninn-dev). Bind was already correct
at :8090 (the stale :8080 was only in the gate repo's own example).

vh 4b54a32d64 feat(mimir-inbox): book-ingestion UI stack on corviduo-dev:8091 (#377) 
WG-internal FastAPI+HTMX front end for large-document ingestion into the
Muninn KB, over the muninn-gate API (browser -> mimir-inbox -> staging ->
path-addressed POST /jobs). Co-located on corviduo-dev with the gate (:8090)
and the worldtree-personal muninn watcher per the operator's 2026-08-01
co-location ruling (reversing the earlier off-box/NFS plan; worldtree-dev
approved the box placement).

- Dockerfile: python:3.11-slim + uv sync --no-dev --frozen (--no-dev is
  load-bearing; the dev group's muninn-dispatch path source is absent in-image
  and INV-MI-7 forbids importing it). Single-stage by design — src/ stays in
  the final image (uv installs the project editable-linked to src/).
- compose.yaml: uid 1000, host-net bind 10.250.50.152:8091, staging :rw,
  TCP-liveness healthcheck (deliberately not coupled to gate reachability).
- Built from vh/mimir-inbox HEAD c8ab38f; deployed + healthy.

Records the open-in-place claim semantics (worldtree-dev, runner.py:362-367)
and the INV-MI-19 retention rule (staged files persist until job terminal;
gate retry returns a false-200 on a swept source) in persistent memory.

vh 966324c5f1 docs(ana-ml2): refresh snapshot + sync README to live GPU state 
The README's running-stacks table had drifted well behind reality (still listed
llama-swap + only the embed/rerank/reward trio). Regenerated system-details.txt
and rewrote the stacks + GPU-allocation sections from a live docker ps +
nvidia-smi (2026-07-22):

- GPU 0 (hot): vllm-aeon-gen (qwen3.6-35b-a3b-heretic, NVFP4) + vllm-charrp-
  reasoning-nvfp4 (char-rp-reasoning, NVFP4), ~42+45 GB.
- GPU 1 (on-demand): granite-4.1-8b, selene-1-mini-8b, Skywork reward,
  Qwen3 embed/rerank, and the Magidonia-24B char-RP GGUF (llama-charrp), ~91 GB.
- Recorded the dormant on-disk stacks and llama-swap's retirement.

vh 603d0ad555 feat(booth): image viewer page with Fit/1:1, download, Esc-back (v0.1.2) 
Clicking a gallery image now opens a dedicated viewer instead of dumping you on
the raw file.

- GET /b/<name>/view?f=<img> — full-viewport viewer (registered before the file
  catch-all so /view wins; non-image f 307-redirects to the raw file, traversal
  and missing f 404).
- Fit (downscale-only) / 1:1 (natural pixels, scroll-to-pan) toggle that only
  appears when the image is larger than the viewport — when it already fits,
  Fit ≡ 1:1 so the toggle is hidden. Re-evaluates on resize.
- Download button + ✕/Esc back to the gallery. Australis-themed, progressive
  JS (degrades to fit-only, no-JS still shows the image + download + back).
- 5 new tests (34 total, all green); verified Fit/1:1/hidden-toggle states in a
  real browser.

vh 775e9804cd feat(booth): upload-for-pickup with human-readable ids (v0.1.1) 
Add a reverse direction to the Booth: the operator (or any client via `curl -F`)
can upload files through the browser and pick them up by a human-readable id.

- POST /upload — streams files to a new booth named with a human-readable id
  (e.g. 4-wombat / star-84), 303-redirects to /b/<id>/ (id in the Location
  header so curl clients can read it). Uploads reuse the whole booth machinery
  (render, per-file download links, 24h TTL sweep, delete).
- Human-readable ids: word+number in either order, collision-checked, from a
  curated 140-word friendly list; secrets-based selection.
- Safety: filenames reduced to a safe basename (no traversal), streaming size
  cap (BOOTH_MAX_UPLOAD_MB, default 1024) + file-count cap (BOOTH_MAX_FILES,
  default 50), partial-write cleanup on any failure.
- UI: Australis-themed upload/drop panel (drag-drop, progressive-enhancement JS,
  degrades to a native file input), a "⬆ pickup" badge on upload booths, a
  pickup banner, and a ⬇ download link on every gallery item.
- python-multipart dependency; homepage tile description updated; 9 new tests
  (24 total, all green).
 2026-07-20 14:44:21 -07:00
vh eaece794d7 fix(booth): button legibility in the Australis theme 
- Wipe "×" is now an opaque dark control-scrim with an always-light glyph, so
  it stays legible over bright thumbnails bleeding through AND in both themes
  (the glyph no longer follows --fg-*, which flipped dark-on-dark in light mode).
- "Wipe now" is a red-outline danger button (bright-red text/border, fills red
  on hover) instead of muted gray-on-transparent that read as illegible.
- Destructive hover text is white on red (was dark-on-red, low contrast).
- Nudge expiry sub-text --fg-muted -> --fg-3 for a bit more contrast.
 2026-07-20 12:52:31 -07:00
vh 3b6fa4a962 style(booth): adopt Corviduo "Australis" theme 
Re-skin the Booth in the fleet's Australis palette (aurora accents, dark-first),
token values adopted from ratatoskr-web's canonical colors_and_type.css:
--aus-* palette, --rk-* console surfaces (#171a23 canvas), Space Grotesk /
Inter / Berkeley Mono stacks, aurora-cyan brand + glow focus rings, red
reserved for the destructive wipe action. Self-contained, no webfont CDN;
light theme via prefers-color-scheme. Only base.html changes (the content
templates keep their class names).
 2026-07-20 12:48:35 -07:00
vh f4a5ba7c31 feat(booth): add The Booth — ephemeral media drop board for CC sessions 
A standing user-level web server (nh3-dev :8090) that renders drop-folders
under ~/booth-data as ephemeral media "booths" so Claude Code sessions can
surface A/B renders and smoke results to the operator, then let them self-wipe.

- Scan-and-serve model, no database, no upload API — a booth is just a folder.
  A folder's own index.html is served verbatim; otherwise an auto-gallery of
  images / webm+mp4 video / audio is rendered, with <file>.txt caption sidecars
  folded in (labels A/B pairs).
- 24h TTL from newest mtime in the tree; background sweeper wipes stale booths.
- Path-traversal + symlink-escape guarded; delete via UI button or DELETE API.
- FastAPI + Jinja2, runs from the checkout under systemctl --user (booth.service),
  alongside the other nh3-dev fleet sidecars. 15 tests, all green.
- Homepage tile added (Apps -> The Booth, siteMonitor /healthz).
- Harden the homepage rsync doc: exclude *.bak* and logs/ so --delete can't
  wipe the host's dated services.yaml backups (footgun found deploying this).

vh a5dcad8bd3 feat(comfyui): switch allocator to cudaMallocAsync (A/B won, fixes LTX OOM) 
Mirror comfy-dev's operator-run allocator A/B result off irv-ml1: drop
--disable-cuda-malloc (ComfyUI keeps CUDA's default async allocator) and
remove PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True (native-allocator-only,
inert under cudaMallocAsync). The native+expandable_segments combo was
fragmenting/over-reserving (~45 GB allocated-but-unused) and OOMing the LTX-2.3
v1.5.0 LoRA stack at Gemma TE load; cudaMallocAsync packs tighter + returns
freed blocks so the job fits (stress test peaks ~82% VRAM, 0 OOM). The
shared-A6000 phantom-OOM that --disable-cuda-malloc guarded is gone since TTS
moved to the 3090 (2026-06-18).

Record the RTXVideoSuperResolution node clone + the nvidia-vfx pip install
(scoped --extra-index-url, uid 1000) in the stacks/comfyui runbook. Flag the
durability split: the node is persistent (basedir/custom_nodes) but nvidia-vfx
lives in the disposable venv (run/), so it must re-run after every fresh

measured real-time cost (calibrated steering free at RTF~0.52, cfg1.5 ~0.625 —
still realtime). Flags the gateway source (~/zonos-gateway on irv-ml1) as not yet

Staged the boot-blocking #365 delta on corviduo-dev DEMO /opt/worldtree/config
per worldtree-dev thread 01KXRE59 (verbatim from their 6a60fe3/b123 blocks):
internal + internal-restricted tiers, four internal-* rules, and the
internal_agent_comms:{enabled:false} gate. Validated via the demo container's
own PyYAML + the exact-set uniqueness guard; no restart (b123 activates off the
bind-mount). Backups .bak-pre-365. Flagged a pre-existing free==pro scope-set

vh 14a0004a47 docs(zonos-engine): capture the production ZONOS2 :1920 launch config (was live-only) 
The Zonos TTS engine that zonos-gateway fronts (irv-ml1 3090, feeds asset-engine +
gateway-chat) ran as a bare native process with its real invocation existing ONLY
in the running process argv — the committed harness/zonos_server.sh on irv-ml1 was
STALE (said A6000/:1919, no perf flags; live is 3090/:1920 with cuda-graph/num-pages/
max-running-requests/memory-ratio). Captured the corrected canonical invocation +
tunables + the containerization plan here so the config survives a process death.

Engine = stock Zyphra/Zonos2 @ 194c0a3 (no custom PFI server code); torch 2.9.1+cu128;
15 GB HF weights. Next: containerize in-place on the 3090 (operator: keep off the
A6000, it OOMs under ComfyUI). Not yet built — this commit is the config capture only.

granite (fleet fan-out summarizer/classifier) had no explicit --max-num-seqs,
so vLLM V1 resolved it to 128 — which caps concurrency BELOW granite's own KV
bound (~192 concurrent @ 1K-token calls, more for shorter classify calls).
Pinned it very high (1024) so the KV pool is the only bound; VRAM-neutral
(the KV pool is util-bound, unchanged). Added the flag to the granite command
+ GRANITE_MAX_NUM_SEQS to the env template. Live applied + verified
(resolved max_num_seqs=1024, seat healthy).

vh a2b026d499 feat(gpu): relocate char-rp to GPU1 + re-optimize both ana-ml2 cards for max context 
Operator-directed 2026-07-16. Moved the char-rp prose seat (Magidonia-24B,
llama-charrp) from GPU0 to GPU1 (CHARRP_GPU_ID 0->1; recreate llama-charrp
only -- the var is shared with the retired GGUF reasoning service), then
re-optimized every context-relevant seat on both cards to native/max context
with acceptable headroom:

  GPU0 (both seats now 256K native, ~14 GB reserve):
    - char-rp-reasoning 150K -> 256K  (heretic2 stack, util 0.38->0.46, 1.56x)
    - gen 256K, max-num-seqs 16 -> 32 (qwen36-27b-aeon, util 0.30->0.42, 5.43x)
  GPU1 (~6.7 GB headroom):
    - granite 64K -> 128K full-chapter (vllm stack, util 0.18->0.27, 1.50x)
    - char-rp 128K native (4 slots), selene/reward/embed/rerank unchanged

All seats gateway-verified healthy. Live .env changes on ana-ml2 with per-stack
backups (*-20260716). Templates updated to match; the qwen36-27b-aeon template
carries a NOTE that its served-name/model still lag the 2026-07-08 gen model swap
(35B-A3B-heretic) -- separate reconciliation. persistent-memory records the full
layout + the util-floor / per-model-KV-cost lessons.

Note: the heretic2-charrp-reasoning stack (char-rp-reasoning's live config) is
still untracked in git -- standing open-loop, its .env change lives server-side only.

vh f25f494f07 fix(vllm): right-size granite util 0.34->0.18 + max-len ->65536 (free ~10.5GB GPU1) 
Operator-directed 2026-07-16: free ~10GB on ana-ml2 GPU1 to relocate a GPU0
model onto GPU1. granite-4.1-8b (fleet summarizer) was over-provisioned at
util 0.34 / max-model-len 131072 with a flat 0.0% KV usage.

Set GRANITE_GPU_MEM_UTIL 0.34 -> 0.18 and GRANITE_MAX_MODEL_LEN 131072 -> 65536
on the live /opt/docker/compose/vllm/.env (backup .env.bak-pre-granite-rightsize-
20260716), recreated vllm-granite ONLY (shared stack). Result: GPU1 62,641 ->
51,897 MiB used (~10.5GB freed, ~45GB free now); KV 6.45 GiB / 84,528 tok /
1.29x concurrency @ 65536; summarizer verified healthy.

The util drop required the max-len drop: on this shared card the effective KV
slope is ~950 MiB per 0.01 util, and vLLM refuses to start unless the KV pool
holds >= 1x max-model-len -- util 0.15 undershot (est max-len 47184 < 65536,
crash-loop, ~2-3 min summarizer outage) before 0.18 landed. 65536 is granite's
precedented summarizer ctx; a summarizer doesn't need 131072.

.env.example updated to the new util (max-len was already 65536 in the template;
live had drifted to 131072). persistent-memory.md updated (parked item closed).

vh 925947c71e fix(litellm): retire image-bench backend, repoint image-judge + qwen-image-bench aliases to gen 
Operator-directed 2026-07-15. The dedicated Qwen-Image-Bench NVFP4 judge
backend on ana-ml2 GPU1 (:8014) was stopped to reclaim ~32GB after the
arbo -> gen hero-judge switch. Both LiteLLM gateway aliases that pointed at
it -- image-judge and qwen-image-bench -- now repoint to the gen backend
(:8015, qwen3.6-35b-a3b-heretic, vision-intact), held at deterministic
judge sampling (temp 0 / top_k 1 / rep_pen 1.05) with enable_thinking:false
(a reasoning preamble breaks json_object). Verified live: both answer with
:8014 down, so they are definitively on gen.

Incidental: backfilled the canonical char-rp-reasoning litellm block, which
had lagged live since the 2026-07-14 NVFP4+MTP seat repoint (model
deckard-pkd-27b -> char-rp-reasoning, top_k 40 -> 20, min_p dropped,
enable_thinking:true added). Required so pushing the canonical would not
clobber the correct live block.

Live changes applied out-of-band (config push + litellm restart + stack
stop on ana-ml2); live config backup at
config.yaml.bak-pre-imagejudge-20260715. Revert path documented in the
config comment. persistent-memory.md updated (parked item closed).

vh d710e56aca memory: migrate persistent-memory.md to two-tier index (53 detail files) 
Split the 53 over-threshold dated log entries (Recent decisions, Tried
and abandoned) into per-entry persistent-memory.d/<slug>.md detail files,
leaving one-line pointers in the index; the 10 short entries stay inline.
Startup index drops 60,527 -> 25,256 bytes (492 -> 270 lines); entry
bodies move verbatim to on-demand detail files, so a fresh session loads
~25 KB instead of ~60 KB and pulls a detail file only when its pointer is
relevant. Top matter (Repo purpose, Tools & conventions, Current state)
is unchanged; both archival back-references preserved.

CLAUDE.md persistent-memory section now documents the index<->detail read
discipline (read the index, pull details on demand, never bulk-read the
dir, commit both together).

Auto-archival still held every dated entry back (all <30 days old); the
July burst begins aging past the 30-day guard ~2026-07-31.

reboot. Root cause: `nofail` drops a mount out of remote-fs.target's blocking
set, so ordering docker After=remote-fs.target does NOT wait for the nofail
NFS mounts. Fix: add x-systemd.before=docker.service,x-systemd.mount-timeout=30
to the 4 NFS fstab lines (direct mount->docker ordering, nofail-safe). Applied
+ verified live (systemctl show docker -p After now lists all 4 mnt-*.mount).

the inference fleet by function into seven groups:

  AI - Inference        gen, char-rp, char-rp-reasoning, Granite summarizer
  AI - Eval & Retrieval Selene, Skywork Reward, Qwen3 rerank/embed, image-bench
  AI - Gateways & Chat  LiteLLM, Asset Engine, Gateway Chat, Open WebUI, ...

  AI - Dormant          stopped rollback seats + retired auditions

Relabel each stack's homepage.group so canonical stacks/ matches the live
containers on ana-ml2, ana-docker, and irv-ml1. Dormant stacks were refreshed
with `docker compose up --no-start` so they carry the new label while staying
stopped (compose-start rollback preserved). settings.yaml drives tab/order/

vh 982c319d9f feat(heretic2-nvfp4): WORKING modelopt NVFP4+MTP seat + full recipe runbook 
The fast char-rp-reasoning seat works: ~77 tok/s (vs GGUF ~59.5, base NVFP4 ~53),
MTP draft-acceptance 32-40%, mean acceptance length 2.19. Same Heretic2/NEO-CODE
model, NVFP4 + native qwen3_5_mtp spec-decode.

Full end-to-end recipe + the four landmines in docs/runbooks/heretic2-nvfp4-mtp-seat.md:
(1) load as AutoModelForImageTextToText not AutoModelForCausalLM (namespace/gibberish);
(2) modelopt format not compressed-tensors (compressed-tensors MTP = 0% accept);
(3) modelopt 0.45 <-> transformers 5.12.1 FusedMoE crash (guarded in quant_modelopt.py);
(4) vLLM 0.24.0 does NOT propagate modelopt exclude_modules to the spec-decode draft
model -> BF16 mtp head gets quantized -> shape crash; no checkpoint config fixes it
(is_layer_skipped is exact-membership not glob) -> fix is a mounted sitecustomize that
force-skips mtp.* in is_layer_skipped (upstream vLLM bug to report).

Scripts: quant_modelopt.py (FusedMoE guard + single-shard export + multimodal load),
finalize_modelopt_mtp.py (splice bf16 mtp), serve_modelopt_mtp.sh, run_quant_modelopt.sh,
sitecustomize-mtp-workaround.py.

vh aca45393c2 fix(heretic2-nvfp4): quant as ConditionalGeneration (namespace fix) + modelopt recipe for working MTP 
Root-caused the NVFP4 gibberish to a quant-namespace bug: quant_nvfp4.py loaded
via AutoModelForCausalLM -> text-only Qwen3_5ForCausalLM -> flat model.layers.* keys,
but vLLM 0.24 serves only Qwen3_5ForConditionalGeneration (whose weight mapper needs
model.language_model.*). Fixed by loading as AutoModelForImageTextToText; NVFP4 now
serves coherent (validated greedy on ana-ml2 GPU0).

Base NVFP4 (compressed-tensors) measured ~53 tok/s (~= GGUF at batch-1, no single-stream
win) and its MTP is 0% acceptance (vLLM's Qwen3_5MTP drafter loads the bf16 mtp head only
off a modelopt main-model checkpoint). Added quant_modelopt.py (nvidia-modelopt PTQ,
matches AEON's NVFP4 W4A4 g16 + lm_head/linear_attn/visual exclusions) as the path to
working native MTP; graft + splice + serve otherwise unchanged.

Captures the full pipeline recipe (graft->quant->splice->config->serve) with every
gotcha found this session, the 3 gibberish suspects, and the diagnostic ladder
(validate native-config no-MTP coherence FIRST) for a fresh session to finish the
chase. Also stages the NVFP4 scripts + 512-row calib. Recent decisions: NEO-CODE
seat swap (R36), webhook ALLOWED_HOST_LIST fix. Lessons: validate-tracer-bullet-first,

vh 462d528bef fix(soong-lab-ci): webhook auto-deploy real root cause = gitea ALLOWED_HOST_LIST + add listener logging 
The ufw fix (prior commit) was necessary but insufficient. The DECISIVE blocker
was gitea webhook.ALLOWED_HOST_LIST = 'external, 10.100.0.0/16' (NH3 only) —
corviduo-dev is 10.250.50.152 (Anaheim), so gitea refused to deliver ('deny
10.250.50.152') and never opened the TCP connection. Fixed to 'external,
10.0.0.0/8' (whole fleet, matches the ufw choice) + gitea restart.

Listener now logs every delivery (source-IP/hmac_ok/ref/action) — the old
log_message=pass silence hid the whole failure. Proven end-to-end: real gitea
delivery -> hmac_ok=True, ref=main, 202 deploying -> green deploy.

vh 4fc0c27485 fix(heretic2-nvfp4): parse tool_call arguments string->dict for Qwen3.6 template 
render-verify caught it: Dvalin's calib tool_calls carry OpenAI wire-form JSON
string arguments, but the Qwen3.6 chat template does .items() on arguments (needs
a dict) → jinja TypeError. Parse string->dict in render_verify + the quant's
load_calib_chat. Confirmed: renders the exact qwen3_coder XML the seat emits
(prefixed bifrost.soong-lab.*, v0.3.13 generate_portrait, <think>, <tool_response>).

quant_nvfp4.py: llm-compressor NVFP4 (Linear only; GDN/vision/lm-head/norms/MTP
kept BF16 per robbatt's deckard recipe + brokkr's spec); text (AEON-baseline) or
chat (production, apply_chat_template renders qwen3_coder XML) calib modes.

Extracted from the deployed backend (bifrost/tools.py) via the venv with a

vh b195815586 docs(soong-lab-ci): correct webhook runbook — root cause was ufw firewall (not SSRF) 
The auto-deploy silently never worked: corviduo-dev's ufw is default-deny and
port 9010 was never allowed, so gitea's webhook deliveries timed out (DROP).
v0.3.6 was a manual deploy; v0.3.7-v0.3.13 never auto-deployed. The setup-time
'test-delivery 204' was gitea queuing, not the listener receiving. Fixed by
'ufw allow from 10.0.0.0/8' (operator-directed). Confirmed end-to-end.
 2026-07-14 08:29:28 -07:00
vh f960a73a79 feat(char-rp-gguf): swap reasoning seat Deckard-PKD → NEO-CODE (Heretic2-Thinking Qwen3.6-27B) 
R36 gate (2026-07-14) validated NEO-CODE ships on all axes: tool-calling 0.967
(attach_tool 1.00, 0 runaways — #355 eliminated), prose genre-artifact-fine
(less clichéd than gen), refusal uncensored-as-spec + CSAM-clean.

#355 root cause was MODEL-level, not the reasoning-budget-forcing bug: Deckard
emitted Qwen's native qwen3_coder XML tool format malformed -> llama.cpp leaked
the closing tags into the arg value -> Bifrost attach_tool schema error -> retry
-> reasoning runaway to max_tokens. NEO-CODE emits the same native format cleanly
on the same seat/parser -> no schema error -> no runaway. The fix was the model
swap; there was never a wrong parser (the XML is Qwen3.5/3.6-native).

- reasoning seat: Deckard-PKD (Qwen3.5) -> NEO-CODE=Heretic2-Thinking (Qwen3.6-27B) Q5
- samplers: card defaults (temp 1.0 / top_p 0.95 / top_k 20 / min_p 0.0), DRY dropped

vh e0f1dbfae6 fix(soong-lab-ci): sync web/ frontend on deploy (was serving stale web) 
soong-dev found the studio serving a stale web/ (52015 vs 55025 bytes — missing the
01-Role section, favicon, thinking-status): the deploy rsynced backend/ but never web/,
so SOONG_LAB_WEB_DIR stayed pinned to the initial manual copy while the backend updated.
Deploy now rsyncs BOTH backend/->studio AND web/->SOONG_LAB_WEB_DIR (read from the env)

--user timer on nh3-dev polls corviduo's last-deploy.json and pings soong-dev via

Point the in-page TTS at the zonos-gateway wrapper on irv-ml1:8890 (direct,
so streaming isn't buffered by LiteLLM): OpenAI-shape body (model: ext-tts,
input, voice), Cora default voice, float32@44.1kHz PCM decode. Quotes are

Drop-in system prompt for an agent whose quoted output is voiced by mOrpheus: speak in
double quotes (only quoted text is voiced), phrase each quoted line as one coherent
utterance (per-quote prosody), and the sparse/boundary/no-stack tag rules (measured
stability on the early checkpoint). Lists the honored tag set.

vh f295cc1f46 fix(gateway-chat): chunk by quoted section, not sentence (prosody) 
Per-sentence chunking generated each sentence cold, flattening intonation/prosody that
spans the whole quoted line. Chunk by QUOTED SECTION instead — each contiguous quote is
generated whole (max_tokens 2400) so its prosody stays intact; multiple quotes in a reply
still play serially on the shared clock. extractQuotes already returns exactly these spans;
dropped splitSentences.
 2026-07-09 01:54:39 -07:00
vh a1f3023f70 feat(gateway-chat): pre-chunk quoted text by sentence, play serially 
Split the quoted dialogue into sentences and stream each as its own short /tts/stream
request (max_tokens 900), queued back-to-back on one shared AudioContext clock (speechHead)
so playback is gapless and in order. First sentence starts fast; each chunk is short so it
generates cleanly (no ramble/cap risk); the next sentence generates while the current plays.
A newer reply supersedes via the ttsGen counter; 🔊 replays.
 2026-07-09 01:49:45 -07:00
vh 033f3685f5 fix(gateway-chat): resume AudioContext on user gesture (no-sound / autoplay) 
Browsers suspend the Web Audio AudioContext until a user gesture; speakQuotes fires on
reply-complete (no active gesture), so a suspended context played silently. Prime/resume
the context on any click or keydown (capture phase) so it's running before playback.
Server side was fine throughout (/tts + /tts/stream both 200 with valid audio).
 2026-07-09 01:41:26 -07:00
vh 0655a37bf6 feat(morpheus): staged clone voices + max_tokens 3500 (context-clamped) 
- max_tokens default 2400->3500 (~42s) in wrapper + gateway-chat client, with a _cap()
  clamp so prompt+gen never exceeds MAX_CTX (4096) — a cloning ref block is ~1100 tokens,
  so an unclamped 3500 would overflow context on the clone path.
- Staged clone voices: /voices dir of <name>.wav + <name>.txt, each encoded to its Orpheus
  reference block at startup; voice="<name>" zero-shot clones it. Beatrice (a chatterbox
  reference) staged as the first normal-voice clone. GET /voices lists baddy + clones.
- compose: mount voices dir + pass MORPHEUS_MAX_LEN to the wrapper (clamp must match engine).

vLLM concurrency (measured, --max-num-seqs 8, 250-tok reqs): near-linear batching — 8
concurrent finish in the same ~2.8s as 1 (707 tok/s, 8.1x single, flat per-req latency).
Chunked-sentence production can fan out for ~8x throughput; CPU SNAC decode is the scale
bottleneck, not generation.

vh f363fe6c84 fix(morpheus): raise TTS max_tokens 1200->2400 (long lines clipped at ~14.6s) 
Cut-offs were the max_tokens=1200 ceiling (~14.6s of audio), not memory (~1250 tokens
<< 4096 context). Diagnosis: the repetition penalty is load-bearing for clean stops —
rep 1.0 => the model never emits end-of-speech and rambles to the cap; rep 1.1 (the
wrapper default) => clean natural stop. So normal lines already complete; only genuinely
long dialogue (>~14.6s, ~25+ words) hit the cap. Raised default + client max_tokens to
2400 (~29s), still within the 4096 context (no memory cost). Verified: a 49-word line
now finishes at 16.73s (was clipped at 14.6s).

vh da7682969b feat(morpheus,gateway-chat): streaming decode — TTFA ~4.5s -> ~0.8s 
Wrapper gains POST /tts/stream: reads the vLLM token stream, decodes SNAC in WINDOWED
CHUNKS (every 6 frames, decode [2 ctx | 6 | 2 ctx] and emit only the middle 6 — context
both sides => seamless), and streams raw PCM16 (24kHz mono) as it generates. Windowed
(not per-frame) because per-frame CPU decode's per-call overhead x ~60 frames serialized
to ~7s (RTF 2.2); windowed keeps up (RTF ~0.97). Whole-clip /tts kept for non-browser use.

gateway-chat plays the stream via the Web Audio API (fetch reader -> int16->float32 ->
scheduled AudioBufferSourceNodes on a running clock; a new reply supersedes the prior
stream via a generation counter; 🔊 replays). Measured: TTFA 0.80s (was ~4.5s whole-clip),
RTF 0.97, full-duration match. CORS already covers the new route.

vh c948013a36 feat(gateway-chat): auto-voice quoted dialogue via mOrpheus TTS 
Gateway-chat now auto-plays quoted text from each assistant reply through the mOrpheus
TTS endpoint. Sidebar gains a 🔊 toggle + endpoint/voice fields (persist in localStorage,
prefilled to irv-ml1:8299 / baddy). On reply-complete, straight and typographic double
quotes are extracted, joined, POSTed to /tts, and the returned WAV plays (click 🔊 to
replay; a new reply interrupts the prior clip).

Requires CORS on the wrapper (page served from ana-docker:8091 fetches irv-ml1:8299
cross-origin) — added CORSMiddleware(allow_origins=[*]) to the mOrpheus tts app (internal-
only endpoint). Verified end-to-end: preflight + POST return ACAO=*, valid 24kHz WAV.

Two-container stack serving MrDragonFox/mOrpheus (uncensored Orpheus TTS, Llama-3.2-3B

SNAC-decodes them to WAV and exposes POST /tts (baddy voice + zero-shot cloning). Deployed

Hard-won config, all encoded in compose/README:
- bf16 REQUIRED: --quantization fp8 destroys audio-token generation (0 valid SNAC frames
  even at greedy). Footprint ~7.9GB.

vh 41305bf62c config(char-rp-gguf): Deckard reasoning seat to full 256K (GDN-hybrid KV cheap) 
Deckard (Qwen3.5-27B) native ctx = 262144; GDN-hybrid arch (16 KV-caching layers) makes KV
cheap (8.7G q8_0 @ 256K vs Magidonia 10.9G @ 128K/40 dense layers). Bumped 40960 -> 262144;
GPU0 ~4G free (static -> stable). Canonical RP-reasoning samplers pending dvalin (card has
only generic base-Qwen3.5 profiles); empirical temp1.0/top_p0.95/top_k40/min_p0.05+DRY0.8 live.

3.716; Pantheon-Reasoning 1.383 (cleanest prose but 7/30 refusals, rejected). Deckard is
GDN-hybrid (16 KV layers) so its ctx scales cheaply (40K->256K ~+7G).

vh 5f79b40982 feat(char-rp-reasoning): Deckard-PKD (Qwen3.5) replaces RpR-v4 after autonomous A/B 
Operator wanted a reasoning-RP model that tolerates DRY (RpR-v4 forbids rep/DRY -> a
1/30 loop tail). Ran the full A/B on brokkr's 30-prompt D1 suite (content-only, slop-scored):

- Deckard-PKD (Qwen3.5-27B, DavidAU creative tune) WON: 0/30 loops, 0/30 refusals, clean
  managed reasoning (native Qwen3.5 <think>/enable_thinking), DRY-tolerant, ~57 tok/s,
  runs on the base llama-swap b8840 image. -> now the char-rp-reasoning seat (:8018).
- RpR-v4: 0 refusals but 1/30 loop (no-DRY). Pantheon-27B: clean slop but 7/30 explicit
  refusals + needs the newer ggml-org/llama.cpp image (Qwen3.6 won't load on b8840).
  Snowdrop + Gembrain (Gemma-4): floored (llama.cpp can't manage their reasoning without
  the vetoed template hacks). Losers kept on disk as alternates.
- char-rp (Magidonia) unchanged; gen unchanged. gateway char-rp-reasoning -> Deckard
  sampler (temp 1.0/top_p 0.95/top_k 40/min_p 0.05; DRY server-side).

vh f49c4e40a3 config(char-rp-gguf): char-rp to full 128K, funded by gen util 0.40->0.37 
Completes the GPU0 rebalance discussed with the operator:
- gen util 0.40 -> 0.37 (qwen36-27b-aeon stack .env) — frees ~2.9G of gen's IDLE KV
  headroom (gen KV usage runs 0-2%; concurrency-at-256K 4.74x -> 3.66x, invisible).
- char-rp (Magidonia) 96K -> 131072 (full native 128K), q8_0 KV ~10.9G.
- char-rp-reasoning unchanged at 40K (QwQ native max).
- GPU0 ~4.4G margin, all 3 seats healthy, verified live.

Deployed .env values already set on ana-ml2; this canonicalizes the intent + rationale.

vh aac4bcfa3e feat(litellm): wire canonical sampler defaults for all 4 gateway seats 
dvalin-smithy canonical set, infra-ops triaged + char-rp A/B-validated on the live serve.

- gen (+summarizer-large twin): presence_penalty 1.0 -> 1.5 (Qwen3.6 non-thinking rec).
- gen-reasoning: temp 0.6 -> 1.0, presence 1.0 -> 1.5 (Qwen general-thinking profile;
  the old 0.6 was the coding sub-profile).
- char-rp: temp 1.0 -> 1.1, min_p 0.03 -> 0.10, top_k 0, NO rep. A/B on 2 dark-romantasy
  prompts: min_p 0.10 richened imagery; repeat_penalty 1.05 REJECTED (injected a stray
  markdown title, hurts Drummer/Magistral RP creativity per the card + dvalin's own note).
- char-rp-reasoning: add explicit top_p 0.95 (else per the RpR card: no rep/DRY/XTC).

vh f5706046b1 feat(char-rp-gguf): max context — char-rp 96K, char-rp-reasoning 40K, q8_0 KV 
Raise both RP seats to near-max context within the GPU0 budget using q8_0 KV cache
(near-lossless 8-bit, ~2x context/GB, flash-attn-backed). Verified coherent on both
(no Qwen KV-quant gibberish) at 64/50 tok/s.

- char-rp (Magidonia): 16K -> 96K (native 128K; 128K would starve the reasoning seat).
- char-rp-reasoning (QwQ): 16K -> 40960 (QwQ native max; beyond needs YaRN).
- kv_unified=true -> a single conversation gets the full n_ctx (slots share the pool).
- GPU0 ~93/97G, ~4.3G margin (gen fixed-util + static KV = stable, no OOM risk).
- New .env knobs: CHARRP_CTX / CHARRP_REASONING_CTX / CHARRP_KV_TYPE / CHARRP_REASONING_KV_TYPE.

char-rp        -> TheDrummer Magidonia-24B-v4.3 Q6_K (Magistral prose, ~65 tok/s,
                  zero refusal, tight POV) via llama.cpp (:8016).
char-rp-reasoning -> ArliAI QwQ-32B-RpR-v4 Q5_K_M (abliterated managed reasoning,
                  ~52 tok/s, reasoning surfaces in reasoning_content) via llama.cpp (:8018).

- New canonical stack stacks/char-rp-gguf/ (llama-server x2, GPU0-pinned, ~86/97G
  co-resident with gen). GGUF sidesteps the vLLM-NVFP4 + Mistral-tokenizer traps that
  killed the Angel serve. Never Ollama.
- Best-of-breed per seat: no single dense 24-32B is both an elite non-thinking prose
  seat AND a clean managed-reasoning seat on llama.cpp (Magidonia [THINK] boundary is
  loose; Cydonia-R1 <think> runs away; QwQ is template-managed). Pantheon-Reasoning-27B
  stays rejected (re-censors in <think>; RpR-v4 abliterated reasoning is the fix).
- Gateway rewired: char-rp->:8016, char-rp-reasoning->:8018, Mistral/QwQ samplers,
  dropped the Qwen enable_thinking kwarg. One-model Magidonia fallback documented.
- Retired the ms32-24b-angel stack.

vh b617a8b674 feat(lora-worker): add optional train_id to POST /train (explicit publish-path namespace) 
comfy-dev's explicit-over-implicit call: arbo now sends train_id, so the
worker no longer derives the loras/trained/{train_id}/ namespace from
output_dir.parent (which coupled it to arbo's handoff layout). train_id is
optional + path-safe-validated; when present it wins, else the path
derivation remains as the fallback. Wired through TrainRequest ->

vh 74dbfafdf1 feat(lora-worker): Phase 2 publish-step — copy succeeded LoRA into ComfyUI loras + published_lora_name 
On a train reaching succeeded, IN ADDITION to output/{name}.safetensors
(unchanged download source), COPY it into ComfyUI's loras search path at
/storetank/arbo/models/loras/trained/{train_id}/{name}.safetensors and
return published_lora_name (the ComfyUI-relative LoraLoader string) in the
terminal GET /train/{id} payload (arbo Phase 2 auto-registration, §4.1/§7).

- Copy not move; a publish failure NEVER fails the train (keeps succeeded,
  omits published_lora_name, logs the reason to the tailable run log).
- INV-T7-safe: a copy to a fixed computed path, no new free-form args.
- train_id derived from the handoff layout (output_dir.parent.name).
- Provisions loras/trained/ (arbotrain 2775, group-write per the Phase-1
  lesson; world-readable/traversable for ComfyUI) via the deploy playbook.
- ComfyUI verified to resolve nested loras subfolders (no flat fallback).

The first real arbo train 422'd: SDXL checkpoints live at
/storetank/arbo/models/checkpoints/ (the 2026-06-13 move to the 1.8TB
/storetank volume), which wasn't in ALLOWED_MODEL_ROOTS — the old roots
predated the move (/worktank/models is gone, /worktank/comfyui host path
is empty; ComfyUI mounts /storetank/arbo/models -> /basedir/models inside
its container). Allowlist /storetank/arbo/models (llmuser-readable,

stronger, unvalidated default. Align the default to the proven value
(operator/per-request can still override). Tests updated (14 green).

Host service (runs as llmuser, owns /opt/fluxgym + GPU access) that runs
sd-scripts SDXL LoRA training on demand for arbo — the infra-ops half of the
in-arbo LoRA training Phase 1 ownership split (vh/arbo
docs/contracts/in-arbo-lora-training-phase1.contract.md §4.1/§2).

- Fixed-invocation only (INV-T7): bounded params -> one sd-scripts command
  shape; every param range/allowlist/path-containment checked before spawn;
  bad request = 422, never a silent downgrade. 14 unit tests green.
- Thin supervisor: never imports torch; subprocesses the fluxgym venv's
  accelerate. 1-job-at-a-time (arbo lease is the serializer, 409 is backstop).
  Durable job records + boot reconciliation (§4.3).
- API: POST /train, GET /train/{id}[/log], POST /train/{id}/cancel,
  GET /gpu-status (per-device VRAM + tts_on_3090 co-OOM signal), GET /healthz.
- Wire-shape (§7 resolved with comfy-dev): shared /worktank/arbo/train handoff
  (group arbotrain, setgid 2770); worker binds 0.0.0.0:8203, arbo reaches via
  host.docker.internal:host-gateway (reachability proven on 172.20.0.1:8203);
  device-aware TTS steering via /gpu-status.

Deployed to irv-ml1 via playbooks/deploy-lora-training-worker.yaml (elway,

New stacks/qwen36-27b-aeon: two co-located vLLM serves on ana-ml2 GPU0 —
gen (:8015, MTP off) and an RP seat (:8016, native MTP) — dense Qwen3.6-27B
(qwen3_5 GDN-hybrid, uncensored/abliterated), ModelOpt-NVFP4, multimodal,
256K context, depends_on-sequenced util split (~0.50/0.45). Each serve
carries a base + `-thinking` served-name so the `-reasoning` gateway records
target distinct LiteLLM deployments — otherwise a thinking-off request mutates
the shared litellm_params and clobbers enable_thinking (the shared-config
footgun that silently disabled char-rp-reasoning).

Gateway (stacks/litellm/conf/config.yaml): gen / gen-reasoning /

the LitBench-less data/judge WIRING check as the correct pre-T1 de-risk

12-row/12-pair synthetic writing fixture — NOT the E-RP corpus — so the
~0 anti-slop delta (-0.002) is the expected null, not an efficacy signal.
Adapter reaped; nothing to A/B. Real behaviour-shift efficacy is a T1-run

vh f8eda1c333 chore(litellm): retire Langfuse — drop success/failure callbacks (redundant + crash-prone) 
Langfuse's ClickHouse member spewed ~94 GB of unrotated logs and filled ana-docker's
root disk (took the fleet host to 100%, 28/48 containers unhealthy). Its trace UI was
redundant with LiteLLM's native logging — store_prompts_in_spend_logs:true already
captures full prompts/responses/tokens/cost/latency at :4000/ui — and nothing used its
unique trace-grouping/eval features (it only received flat gateway success_callbacks).
Removed the callbacks (gateway observability stays fully native) and tore down the
6-container langfuse stack + volumes on ana-docker. Re-add the callbacks if it returns.

vh 7819f96003 feat(litellm): add gen-frontier / gen-frontier-reasoning aliases (→ GLM 5.2) 
Capability aliases for the PAID frontier tier, mirroring glm-5.2 / glm-5.2-
reasoning (thinking off / on) → openai/glm-5.2 @ z.ai. Worldtree binds these for
a frontier-grade generation/reasoning capability so the backing frontier model
can be swapped gateway-side (operator jump-started WT's request). PAID: only
all-proxy-models / explicitly-scoped keys reach them; the free all-agents-local
key stays fenced off z.ai spend. Verified both resolve + route to GLM 5.2.
 2026-06-20 10:14:28 -07:00
vh d0eb09cac1 fix(litellm): remove the * → llama-swap wildcard (decommissioned backend) 
llama-swap (ana-ml2:9292) is decommissioned (:9292 confirmed down), so the
catch-all wildcard routed every unmatched / typo'd / stale model name to a DEAD
backend, surfacing a misleading "Connection error" instead of a clean
"model not found". This is the exact footgun that silently swallowed Worldtree's
defunct model names (mistral-small-4 etc.) instead of erroring. Removed (operator
call) so unknown models now 404 loudly. Verified: gateway healthy post-restart,
a bogus model name now returns a clean not-found error, real aliases (gen) still
serve. Re-add explicit per-model entries if a swappable zoo ever returns.
 2026-06-20 10:08:20 -07:00
vh d3721034c1 feat(litellm): Worldtree capability aliases (chat-judge, reranker, scalar-judge) 
Stand up the gateway-side capability aliases for the role→capability model
indirection (worldtree-dev's transparent-swap direction; operator: no wt-
prefix, reuse the existing summarizer/classifier/gen alias convention).

- chat-judge  -> selene-1-mini-8b (mode chat)  — WT selene-judgment role.
- reranker    -> qwen3-reranker (mode rerank)  — generic name for the cap.
- scalar-judge -> Skywork-Reward-V2 via a pass_through_endpoint to ana-ml2:8003
  (LiteLLM has no reward/pooling MODE, so it's a passthrough, gateway-key-gated;
  consumers hit /scalar-judge/<route> e.g. /score|/pooling|/classify).

Deliberately NO generic `embedding` alias: embedding vectors are model-specific
(not swap-transparent), so that capability stays `qwen3-embedding` — the model-
specific name is the guardrail against treating it as freely swappable. Verified
all three live (chat-judge 200, reranker present, scalar-judge passthrough 200
returning a Skywork reward). Deployed + gateway health-gated.

vh cd92b85157 feat(omnivoice): tune streaming defaults (16-step + aggressive packing) 
Empirical follow-up to the streaming /tts smoke test on the 3090. OmniVoice
is diffusion: a ~fixed per-call overhead (~1.5s at 32 steps, ~0.7s at 16)
dominates regardless of chunk length, so the upstream-claimed 40x RTF does
NOT hold here (measured ~2.8x/32-step, ~5.6x/16-step) and the chatterbox-
tuned scheduler over-chunks and starves.

- Streaming /tts defaults to num_step=16 (TTFA ~1.5s -> ~0.7s); batch
  /v1/audio/speech stays num_step=32 for quality. Per-request override intact.
- Scheduler prior raised to rtf_prior=20 (env OMNIVOICE_STREAM_RTF_PRIOR,
  wired through compose + .env.example) so it packs whole-text-minus-first-
  sentence into a few chunks: validated ~3 chunks, no starvation, total wall
  ~= one-shot, less per-chunk silence padding.
- Docs corrected: the "sub-second / 40x" claims were wrong; streaming has a
  diffusion TTFA floor (~0.7s) and wins mainly on long replies. chatterbox-
  fast (autoregressive, ~0.5s TTFA) stays the lowest-latency front-end;
  OmniVoice is the multilingual / voice-design complement.
 2026-06-19 22:58:55 -07:00
vh 288d085236 feat(omnivoice): streaming /tts + language-safe sanitizer 
Add a live-consumer streaming path and text sanitation to the OmniVoice
wrapper, so it can front speech-to-speech chat engines (not just the
asset-engine's batch WAV use).

- POST /tts: chunked 24 kHz mono s16le PCM (or open-ended WAV), driven by
  the adaptive buffer-ratchet scheduler. Emits the first sentence
  immediately, then ratchets chunk size up on OmniVoice's ~40x realtime
  headroom -> sub-second time-to-first-audio. Wire-compatible with
  chatterbox-fast /tts (both 24 kHz mono PCM). Batch /v1/audio/speech is
  unchanged for asset/file callers.

- scheduler.py: VENDORED byte-faithful copy of chatterbox-fast's pure-
  Python (torch-free) scheduler, pinned to commit 7631462 (v0.1.0/v0.1.1).
  Vendor-copy over a shared package (operator call 2026-06-19): the module
  has no GPU deps, so reuse it without dragging chatterbox-fast's torch
  tree into this image. Promote to a shared package only on a 3rd consumer
  or real drift.

- sanitize.py: language-safe TTS sanitizer run on both endpoints. Strips
  markdown, <think> blocks, HTML, and model control tokens; deliberately
  SKIPS the fork's English-only number/phone normalization that would
  corrupt OmniVoice's 600-language input. Preserves [laughter]-style tags.

- Refactor: shared GenParams base for SpeechRequest + TTSStreamRequest;
  single GEN_LOCK serializes generation (single-stream interactive).

- Dockerfile/playbook: copy + upload the two new modules; build-time
  `import app` smoke; correct stale "Gradio demo / no FastAPI" comments.

Static-verified (JS syntax + element-id consistency); headless smoke was blocked
by a shared-browser version skew in /opt/ms-playwright, not a tool defect.

which point the cleaned config drops them. No bounce performed.

Same Qwopus gen model as gen / gen-reasoning (served-name qwen3.5-122-a10b @
:8013, thinking off/on respectively), but each bakes a dummy 'noop' function tool
+ tool_choice:none into litellm_params so a NON-EMPTY tools array always reaches
vLLM — for consumers where the global strip_empty_tools hook isn't the right fix
(they need a valid tools structure present, not stripped). tool_choice:none means
the noop is never called. api_base = the real LAN endpoint http://10.250.50.54:8013
(the requested http://vllm:8000 template wouldn't resolve from the ana-docker
litellm container). Verified: gen-nt + gen-reasoning-nt both survive a client
tools:[] send; noop never invoked; reasoning split intact.

Replaces the bjk110 text-only qwen3.5-122b as the `gen` model on ana-ml2 GPU 0.
OpenYourMind/Qwopus3.5-122B-A10B-Kimi-K2.6-destilled-abliterated-NVFP4 — Kimi-
distilled, abliterated, NVFP4, and crucially VISION-INTACT (serves as plain
multimodal, no text-only patch). Served as qwen3.5-122-a10b so the litellm
gen / gen-reasoning / qwen-large records route here unchanged.

Tuned for full native context on the 96GB Blackwell:
- stable vLLM image + fp8 KV → 11GB pool = 870,014 tokens = 3.32x concurrency
  at the full 262144 (256K) window. Nightly+turboquant-4bit was unnecessary.
- CUDA graphs ON (no --enforce-eager) → 92.7 tok/s warm single-stream.
- util 0.95 + PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True — 0.96 OOM'd by
  0.1GB on the 3.09GB FusedMoE transient workspace (the hard floor; defrag
  reclaims the 4.2GB fragmentation, 0.95 adds margin).
- max-num-seqs 16 (short reqs fan out ~16x32k; 256K reqs pool-limit to 3.32x).

the bjk110 serve command shipped --reasoning-parser qwen3 but no tool flags. Qwen3.5 emits XML
tool calls (<tool_call><function=NAME><parameter=K>V</parameter></function></tool_call>), NOT
Hermes JSON — so `hermes` mis-parsed to raw text; `qwen3_xml` is the correct parser. Reasoning +
tools coexist (gen-reasoning keeps its thinking split). Verified live: a get_weather request

  discoverable at the new /v1/audio/instruct-items endpoint (23 items).
- language (Auto + 647, new /v1/audio/languages endpoint), speed, duration.

  postprocess_output; plus a generation_overrides JSON passthrough for expert
  GenerationConfig knobs (t_shift, layer_penalty_factor, position/class temperature,
  audio_chunk_*).

vh a8550ad4bc feat(irv-ml1): pin comfyui to A6000 + torch-pin; parakeet -> 3090 (VRAM consolidation) 
Operator consolidation (2026-06-18): give ComfyUI the full 48 GB A6000 and move the
audio/TTS zoo to the 3090.

- comfyui: NVIDIA_VISIBLE_DEVICES all -> 1 (A6000 only), + DISABLE_UPGRADES=true to
  pin torch at 2.12.1+cu129 so the mmartial boot script stops auto-upgrading it and
  the compiled SageAttention kernels stay matched (comfy-dev torch-pin, approved).
- parakeet: NVIDIA_VISIBLE_DEVICES all -> 0 (3090).

Other GPU reassignments are deployment-side (not repo compose): chatterbox-fast via
its .env CBF_GPU_DEVICES=0; vibevoice device_ids ["1"]->["0"] (deployed from
/worktank/vibevoice/build); yt-voice-clipper worker via its override. dia2-2b,
ace-step, csm-expressiva downed (stale/unused).

Result: A6000 = ComfyUI alone (48.3 GB free); 3090 = chatterbox + parakeet + the
on-demand audio (vibevoice/ytvc/kokoro). SageAttention rebuilt against the pinned
torch; OOM cmdline (COMFY_CMDLINE_EXTRA) preserved; /object_info still lists the 9
acceleration nodes.

vh f566f61b24 feat(stacks): mistral-small-4-heretic drop-in (abliterated NVFP4 backend swap) 
Serves the in-house abliterated Mistral Small 4 (heretic NVFP4, vision-intact)
under --served-model-name mistral-small-4 on ana-ml2 GPU0:8010 — a true drop-in
for the official mistral-small-4 backend. Both litellm entries (mistral-small-4 +
mistral-small-4-reasoning) route here with no litellm change.

GPU0 fits one mistral-class model, so this is a backend swap, not a co-tenant:
bring up after downing the official stack; revert by downing this and up-ing the
official. Verified live through the gateway: standard returns clean answers,
reasoning populates reasoning_content (the [THINK] split). Checkpoint built per
tools/mistral-small4-nvfp4/.

vh dd3a5c93fd feat(tools): Mistral Small 4 NVFP4 build pipeline (quant + HF->native converter) 
Quantize a HF-format Mistral Small 4 (Mistral3ForConditionalGeneration MoE) to
NVFP4 with the vision tower intact, then convert HF NVFP4 -> Mistral native so
vLLM can serve it (there is no HF Mistral4 serving path in any vLLM version).

Built + validated end-to-end on ana-ml2 for the abliterated character-model
successor (darkc0de/Mistral-Small-4-119B-2603-heretic): quant -> dry-run (clean
vs the official native NVFP4 reference) -> convert -> serve-test (loads on the
native loader, correct text, vision functional).

Converter scaffold came from worldtree-codex (bf16 bin maps + fused-expert
split); fixed here: NVFP4 layer regexes (keep the `model.` prefix) + non-mmap
shard reads (ZFS large-mmap ENOMEM). nvfp4_quant.py is local. README documents
the pipeline + every gotcha that cost a failed run. Homed here per operator
direction (not Worldtree).

vh fc88eff06e feat(ana-ml2): durable vm.overcommit_memory=1 sysctl playbook 
ana-ml2 ran overcommit_memory=0 with zero swap, capping the CommitLimit at
~RAM/2 (~283 GB of 566 GB). The resident vLLM services commit ~224 GB, so a
large model-file mmap (the 50 GB NVFP4 shard during HF->native conversion, or
a vLLM model load) failed with ENOMEM despite ~393 GB of RAM actually free.

overcommit_memory=1 is the conventional setting for ML hosts that mmap large
files. A drop-in under /etc/sysctl.d/ makes it reboot-durable. Operator-directed
permanent (2026-06-17). Idempotent via when:; sudo tee for the root-owned path
(elway runs steps as the SSH user, so a shell > redirect can't write there).

GLM 5.2 released ~2026-06; confirmed reachable with our existing
Z_AI_API_KEY (z.ai /models lists glm-5.2; a live completion returned
clean). Added two model_list entries mirroring the glm-5.1 pattern:
glm-5.2 (thinking DISABLED by default, per the 2026-06-11 operator call)
and glm-5.2-reasoning (thinking ENABLED, opt-in). Deployed to
ana-docker /opt/docker/conf/litellm/config.yaml, litellm restarted,

Proven 2026-06-16 diagnosing arbo run #5/task 1175: the RUN-level

GET /api/v1/repos/{o}/{r}/actions/jobs/{job_id}/logs returns the full
plain-text log (claude-bot basic-auth, internal :3000) — no UI needed.

vh 03358dccd1 arbo: mount repo pyproject.toml ro into the engine (catalog_version observability) 
/healthz catalog_version read the BAKED package version (importlib.metadata),
so a catalog/frontend-only webhook deploy (no image rebuild) left it stale —
v0.12.4 data went live but /healthz still reported 0.12.3. comfy-dev's v0.12.5
reads comfy_catalog.__version__ from the repo-root pyproject.toml; mounting it
on the same checkout mount (catalog/graphs/frontend) makes /healthz report the
MOUNTED version after a catalog-restart. Falls back cleanly if absent.

Pushed to irv-ml1's host compose + validated via `docker compose config`
(bind -> /app/pyproject.toml:ro resolves). Recreate deferred to comfy-dev's
imminent v0.12.5 rebuild (the mount is inert for v0.12.5 itself, which bakes
its own version — it only matters for subsequent catalog-only deploys — so no
separate prod blip). Requested by comfy-dev (engine owner), althing thread
01KV95R88A3Y.

vh 3a7236d51f playbook: put uv/uvx on the irv-ml1-arbo runner PATH 
The irv-ml1-arbo Gitea Actions runner (host-executor as lkraven under
systemd) gets the bare service PATH (/usr/local/bin:/usr/bin:/bin), which
omits ~/.local/bin — so the CI uv bootstrap failed with "uv: not found".
Symlink uv/uvx into /usr/local/bin (on the systemd PATH) to fix it and
retire the per-run curl|sh bootstrap. Idempotent (creates: guard);
re-applies cleanly after a runner rebuild. Authorized by comfy-dev
(engine owner) per althing thread 01KV94VTS27B.

vh 984ca3d383 feat(tools): single-file gateway chat playground 
Zero-dependency, zero-backend HTML chat UI for the LiteLLM gateway. The
browser talks straight to :4000 (gateway CORS is open), so it's just one
file you open — no container, no stack. System-prompt textarea, model
datalist, streaming SSE, renders reasoning_content for the -thinking/
-reasoning models, settings persist in localStorage.

Deliberately never sends a `tools` field, sidestepping the vLLM "tools
must not be an empty array" bug that breaks the LiteLLM admin UI
playground for vLLM-backed models (litellm #6228; the gateway's
strip_empty_tools hook can't reach the UI's in-process completion call).

Verified against the live gateway: streams + parses a real completion
with no tools sent.
 2026-06-16 01:40:30 -07:00
vh d1bea13994 fix(litellm): strip empty tools:[] before forwarding to vLLM 
vLLM's OpenAI server 400s on an empty tools array ("tools must not be an
empty array"), which broke every gateway call carrying tools:[] (clients
that send it to mean "no tools" -- OpenAI tolerates it, vLLM does not).
drop_params doesn't help: it drops unsupported PARAMS, not empty VALUES.

Add a CustomLogger async_pre_call_hook (conf/strip_empty_tools.py) that
pops an empty/None tools field (+ orphaned tool_choice) before forwarding,
registered globally via litellm_settings.callbacks so it covers every
vLLM-backed model, not just mistral-small-4. Mounted at
/app/strip_empty_tools.py beside config.yaml (LiteLLM resolves callbacks
relative to the config dir). Surgical: only fires when tools is present
and empty; real tools pass through untouched.

Verified on live gateway (1.87.0): mistral-small-4 and granite-4.1-8b
with tools:[] now 200 (were 400); no-tools baseline unchanged; a real
tool still passes through.

selene: AtlaAI Selene-1-Mini-Llama-3.1-8B judge restored on vLLM after the
llama-swap teardown took its Q6_K GGUF offline. FP8 (dynamic --quantization
fp8; FP8 >= the validated Q6_K fidelity, and text-only Llama so no vision-
tower-noise risk; NVFP4's W4A4 too aggressive for a precision judge). GPU1
util 0.13 (8.51 GiB weights + 2.53 GiB KV, 32K ctx, 1.27x concurrency),
~11 GB GPU1 buffer left. Gateway selene-1-mini-8b → :8011 (shadows the *
wildcard that used to reach it via llama-swap). Judge smoke: scored an
unfaithful claim 1/5 correctly.

mistral-small-4: max-model-len 131072 → 262144 (full native 256K) for
novel-length consistency-checking. KV pool is util-bound (~862K tokens), so
256K costs no extra VRAM — max concurrency just drops to 3.29x at full length.
max-num-seqs 64 → 32 keeps the warmup transient flat (scales with seqs × len),
so it fits the tight GPU0 (free unchanged at 5.2 GB). Verified loaded + healthy.

vh 9a49963d07 feat(mistral-small-4): pin v0.22.0 for working VISION baseline + reasoning entry 
Operator needs a verified-working vision tower as the abliteration/tuning
baseline. vLLM 0.23.0 crashes Mistral multimodal at startup (#44911
fetch_images regression, ~0.22.1+). Pinned the Mistral container to
v0.22.0 — the last pre-regression release — which loads the NVFP4
(compressed-tensors) AND serves vision: verified a half-blue/half-red
image read correctly ('left blue, right red'). Dropped --limit-mm
(vision re-enabled). qwen36 stays on 0.23.0 (separate container; needs it
for its ModelOpt NVFP4).

- gateway: add mistral-small-4-reasoning. Operator asked for effort=medium
  but Mistral's reasoning_effort is BINARY (none/high only — medium 400s);
  set to 'high' (sole reasoning-ON level). NOTE: reasoning fires but
  reasoning_content-splitting is unreliable on v0.22.0 (lands in content);
  clean split would need 0.23.0, which breaks vision — vision prioritized.

  (fetch_images bug); loaded with --limit-mm-per-prompt image/video=0.
  Remove the flag to restore vision once vLLM patches it.

The nvidia ModelOpt NVFP4 MoE that failed on vLLM 0.19.1/0.22.0 (#44081)
loads clean on 0.23.0. Cut prod qwen36 FP8→NVFP4: ~20.4 GiB weights vs
~34 (~40% lighter, ~13 GB reclaimed on GPU 1), faster single-stream on
Blackwell FP4 cores, vision tower preserved (comfy-dev real anatomy-judge
A/B on 16 prod images: PASS; brokkr text/speed: parity bar a minor
multi-step-chained-reasoning slip that doesn't bite the judge role).

- compose: pin image by 0.23.0 digest, drop --kv-cache-dtype fp8 (fp16 KV
  — the freed room buys full-precision KV), util 0.46→0.32.
- GPU1 rebalance (pinned): granite restored 0.24→0.34 / 65536→131072
  (undoes the FP8-era sacrifice); trio unchanged; total ~0.82, ~24 GB free.
- gateway model name qwen3.6-35b-a3b unchanged (now NVFP4 behind it);

The qwen3.6-35b-a3b VL checkpoint is a single hybrid model with a per-
request enable_thinking switch (Qwen3-style), defaulting thinking ON.
Make the default non-thinking and add an opt-in reasoning variant,
mirroring the existing glm-5.1 / glm-5.1-reasoning gateway split.

- qwen36-vl compose: add --reasoning-parser qwen3 (model-matched) so the
  single :8007 endpoint splits <think> into reasoning_content when on and
  routes all output to content when off — serving both modes cleanly.
- litellm gateway: base qwen3.6-35b-a3b pins chat_template_kwargs
  enable_thinking=false (non-thinking default); new qwen3.6-35b-a3b-thinking
  pins enable_thinking=true (opt-in reasoning). Same upstream checkpoint,
  no extra VRAM/container.

Deployed + verified on ana-ml2 (vLLM recreated, healthy) and ana-docker
(litellm reloaded): default returns a direct answer with no reasoning_content;
-thinking returns cleanly-separated reasoning_content, no raw tag leak.

131K->64K, embed/rerank 0.05->0.03 (reclaimed util-reservation waste). Verified:
vision correct, 20-concurrent/endpoint load test = no OOM (~7.5 GB headroom).

Drop the llama-swap qwen3.5-9b GPU-0 pin (GPU 0 freed for the creative-writing

vh db97899037 feat(arbo): disable ENGINE_TOKEN bearer auth on prod (WireGuard = boundary) 
Operator decision 2026-06-13 (relayed by comfy-dev, confirmed in-session):
turn off the prod arbo engine's bearer auth and rely on the WireGuard
perimeter. Reverses ADR-0001's open-auth-hole-closed posture (comfy-dev owns
the ADR update on the vh/arbo side).

The app's protected-gate no-ops only when ENGINE_TOKEN is ABSENT — an empty
string still gates (verified: ENGINE_TOKEN="" -> /workflows 401). So both
inject paths are removed: the compose environment line is commented out and
the .env line deleted on the host. Result: tokenless GET /workflows 200 (was
401), matching the dev engine. Original token preserved in the host's
.env.pre-auth-off.bak for re-enable.

playbooks/arbo-disable-engine-token.yaml captures the reversible procedure.

Benched granite prefix caching at ~6.5x faster TTFT (45ms cached vs 292ms
uncached) on a shared ~4.5k-token summarizer template. granite already had it
on by vLLM-v1 default; pinned explicit so a version flip can't silently disable
it. qwen (nightly) defaulted it OFF -> flipped on (free for the text-chat path,
marginal for vision where each image is a distinct prefix). Soft/evictable KV,
zero memory change (GPU1 still ~3.7GB free), all 5 services healthy.

Reclaimed Qwen3.5-9B's over-provisioned KV (20x conc @ 32k) and handed it
to granite. granite: 51200->131072 ctx (305k-token pool, 2.33x worst-case;
PagedAttention => ~2.2x more short-request concurrency from the bigger pool),
util 0.36->0.35. qwen: 32768->65536 ctx (8.13x), util 0.40->0.35. Trio
unchanged (chunked inputs, 8k plenty). Leaves ~3.7GB free on the shared
card. Start-order matters (trim qwen first, then grow granite) — vLLM
requires free>=util*total at startup.

ComfyUI's ~325G model tree moved off the near-full worktank NVMe (97%->26%,
342G free) to /storetank/arbo (roomy SATA SSD on irv-ml1), overlay-mounted
back at /basedir/models so ComfyUI behaviour is unchanged. rsync byte-verified

Qwen3.5-9B vision-language served FP8 on ana-ml2 GPU1 (co-located with
granite + the embed/rerank/reward trio; GPU0 kept free for hot-loading
large models), :8007, fronted by LiteLLM as qwen3.5-9b-fp8.

Pinned to vllm/vllm-openai nightly@sha256:49211ab2 — :latest (v0.19.1)
quantizes the VL vision tower under fp8 and garbles vision; the nightly
correctly excludes it (LM stays FP8, vision tower BF16). util 0.40

SGLang 0.5.13 confirmed to support our formats on Blackwell sm_120
(compressed-tensors NVFP4 W4A4, fp8, modelopt_fp4, petit_nvfp4, fp4_e2m1 KV),
so the bench can be a real NVFP4 head-to-head. Parameterized compose (model/
quant/GPU via .env) + a common streaming load generator (bench.py: agg tok/s,
TTFT p50/p99, TPOT) so both engines are driven identically on an exclusive GPU.
Bench-oriented; promote to a real stack only if SGLang wins. Launch deferred
until the NVFP4 eval frees a GPU.

vh 19a07b96ab tune(vllm): re-floor trio GPU util for Blackwell (96GB), 20x-parallel-stable 
Ada->Blackwell swap doubled card VRAM, so the Ada-era fractions (0.07/0.07/
0.18) reserved ~2x the bytes for the same models. Empirically re-floored via
0.01-step climb until each service was stable under 20x parallel inference:
embed/rerank 0.05 (load-floor for the 0.6B models), reward 0.10 (the real
over-provision). Frees ~11 GB on GPU 1. Live .env on ana-ml2 already applied.

vh edf0f912f8 feat(llama-swap): pin to GPU 0, reserving it for large-model hot-loads 
ana-ml2's Ada->Blackwell swap (2x96GB) frees GPU 0 entirely. Pin llama-swap
to GPU 0 via NVIDIA_VISIBLE_DEVICES so on-demand large-model hot-loads land
there, off GPU 1 where the always-on vLLM services (granite + embed/rerank/
reward) live. Closes the long-standing 'pin llama-swap to GPU 0' item.

New stack mirroring the canonical convention for the Arbo (catalog) engine,
co-located beside comfyui on irv-ml1 per ADR-0001 D1/D3:

- engine<->ComfyUI over traefik-net container DNS (http://comfyui:8188),
  SSH dependency eliminated; file ops bind the shared basedir input/output
- named local-disk volumes for the gallery SQLite (arbo_db, restic-backed)
  and hero images (arbo_heroes); catalog as a ro git-checkout mount (D2)

## Model quantization
Quants are hard-fought and we have repeatedly re-litigated the same lessons.
**`docs/pfi/model-quantization-playbook.md` is the durable home for the
transferable ones** — scheme choice, the recurring landmines, the acceptance
gate and its measurement traps, and a superseded-claims table. Read it before
starting any quant; read it *instead of* the per-model runbooks for general
guidance (several of those carry claims that are now false, and say so).
When a quant teaches something **model-agnostic**, it goes in the playbook and
the per-model README links up. When it's **model-specific**, it stays in the
per-model artifact. If you catch yourself writing a fresh "Gotchas" section that
repeats the playbook, you are re-litigating — record the delta in the playbook
instead. When a playbook claim turns out wrong, don't just fix it: add a dated
row to its superseded-claims table so old docs stop misleading people.
## Training throughput
Same contract as quantization, different subject: **`docs/pfi/training-throughput-playbook.md`
is the durable home** for why a training run is slow — the 10-minute scaling
triage that names the regime before you profile, the padding/masking landmines,
the profiler traps, and its own superseded-claims table. Read it before
hypothesising about kernels.
The instruments are committed at [`scripts/training-probes/`](scripts/training-probes/)
with raw output kept alongside, so the claims can be re-derived rather than
taken on faith.
⚠ **Measure before you argue.** The playbook exists because a four-model
frontier panel produced four self-retractions in ninety minutes on this
question, and every one of them was a derivation while every survivor was a
measurement.

## Internal DNS (`*.internal`)
Fleet hosts have names: `<host>.<site>.internal`, sites `ana` / `esh` / `nh3`.
`dns/internal.yaml` is the source of truth; the AdGuard resolvers are derived
state.
```bash
$EDITOR dns/internal.yaml
scripts/dns-sync.py --dry-run # diff
scripts/dns-sync.py # apply
```
The sync is authoritative **within `.internal` only** — names added by hand in
the AdGuard UI get deleted, but rewrites in other zones (ESH's `esteban.net`
entries) are left alone. See `dns/README.md`, especially the IPv6 note: v6
addresses only go in the file once they are pinned statically on the host,
because SLAAC addresses rotate and a stale record is worse than none.
## Working rules
- **Copies, not symlinks.** Files here reflect what's on the server at the time of the last sync. When you edit here, the server doesn't change until you deploy.

# Fleet internal DNS — `*.internal`
Names for fleet hosts so nobody has to remember addresses. Built 2026-08-19
because IPv6 makes memorising them hopeless — and, more to the point, because
v6 addresses are *derived* rather than assigned, so they cannot be reliably
memorised **or** written down once and trusted.
```
dns/internal.yaml the source of truth — hosts, sites, aliases
scripts/dns-sync.py reconciles the resolvers against it
```
## Adding a name
Edit `dns/internal.yaml`, then:
```bash
scripts/dns-sync.py --dry-run # see the diff
scripts/dns-sync.py # apply, with a prompt
```
That is the whole workflow. It is deliberately the same shape as
`deploy-stack.sh`: a file in git is the intent, the running system is derived
state, and you see a diff before anything changes.
## Naming
`<host>.<site>.internal`, sites **`ana`** (Anaheim colo), **`esh`** (home lab),
**`nh3`** (office).
`.internal` is ICANN-reserved for private use, which is why it is used here
rather than `.local` (reserved for mDNS — the old `searxng.pfi.local` was a
standards collision that happened to work) or an invented TLD that could later
collide with a real one.
**Every name is published to every resolver.** The site label says where a host
*is*, not which resolver knows about it — `ana-docker.ana.internal` resolves
from ESH and NH3 too.
Irvine is not a fourth zone: `irv-ml1` is reachable only through NH3's
WireGuard tunnel and numbered out of NH3's `10.100.79.0/24`, so it lives under
`nh3`. Worth revisiting if Irvine ever becomes a site in its own right.
## The resolvers
| site | resolver | API port |
|---|---|---|
| ana | ana-docker `10.250.50.70` | **8053** |
| esh | esh-docker-vm `10.0.50.45` | 8080 |
| nh3 | nh3-docker `10.100.50.40` | 8080 |
ana is the odd one out — `:8080` and `:3000` were already taken on that host —
so the port is carried per-site in `internal.yaml` rather than assumed by the
script.
The colo resolver (`stacks/adguard-ana/`) was stood up as part of this work;
before it, colo hosts resolved straight against `1.1.1.1` and the site had no
way to answer for internal names. ESH and NH3 run older, unmanaged compose
files, left alone on purpose — adopting three live resolvers into this repo
while also introducing a new naming system is two risky changes at once.
## Two properties worth not breaking
**Authority is scoped to the zone, not the resolver.** Only rewrites ending in
`.internal` are managed. The ESH resolver carries hand-made `esteban.net`
entries that predate this system; the sync reads them, ignores them, and leaves
them alone. If this ever grows to manage another zone, that scoping is the
thing to be careful with — resolver-wide authority would silently delete
somebody else's work.
**Within the zone it is authoritative.** Names added by hand in the AdGuard UI
*will* be deleted by the next sync. That is the point: one place to look.
## Credential
`scripts/dns-sync.py` authenticates as a dedicated **`infra-ops`** AdGuard user,
not as the operator's account, and pulls the password from the vault:
```bash
secret get nh3-dev/adguard-infra-ops-password
```
⚠️ The vault appends a trailing newline on read. The script strips it, because
a password carrying a stray `\n` fails auth in a way that looks exactly like a
wrong password.
The existing `lkraven` AdGuard user was left untouched. Config backups from
before the user was added are on each resolver as
`AdGuardHome.yaml.bak-preinfraops-*`.
## ⚠️ IPv6 — the reason this exists, and still the unfinished half
The `v6:` column is empty and that is correct as of 2026-08-19: **no fleet host
has a global IPv6 address yet.** ESH's `/56` is live only on `esh-cameras`,
NH3's LANs are back to `ipv6_interface_type: none`, the colo has no v6 at all.
When v6 arrives, **do not paste in whatever `ip -6 addr` shows.** SLAAC gives
hosts either EUI-64 addresses (MAC-coupled) or privacy-extension ones (which
rotate), and UniFi has no v6 equivalent of a DHCP reservation. An address only
belongs in this file once it has been pinned **statically on the host itself**.
A record that silently stops matching reality is worse than no record — the
name keeps resolving and starts lying.
The suggested convention when that happens: give each server a static address
out of its site's `/64` whose low-order bits echo the v4 host octet
(`esh-docker-vm` at `…::45`), so the addresses are both declarable and
semi-memorable.
## Not migrated: `matrix.pfi.local`
`searxng.pfi.local` moved to `searxng.ana.internal` (both names still route,
so nothing breaks mid-migration; drop the fallback `Host()` in
`stacks/searxng/compose.yaml` once the Traefik log shows the old one unused).
**`matrix.pfi.local` was deliberately left alone.** A Matrix `server_name` is
baked into every user ID, room ID and signing key, and federation identity is
derived from it — renaming it is not a DNS change, it is rebuilding the
homeserver's identity and invalidating its history. It stays on `.local`.
## Still open
Colo hosts still point at `1.1.1.1`, so they do not yet *use* the new resolver
— they only get answers if something asks it directly. Repointing a whole
site's DNS is a bigger change than standing the service up, so it is a separate
operator-approved step.

# Arbo ComfyUI model catalog
**Host:** irv-ml1 · **Path:** `/storetank/arbo/models` (SATA SSD; overlay-mounted into
the arbo / comfyui container at `/basedir/models`). **502 G** as of 2026-06-13.
The single live model tree arbo (hero / asset generation) consumes. On 2026-06-13 it
**absorbed 177 G** of gen-agnostic utilities + the SDXL/Pony stack, migrated from the
now-decommissioned `/storetank/image-models/comfy` archive — see
[`storetank-image-models-archive.md`](storetank-image-models-archive.md) for that record.
## Per-category sizes
| Category | Size | Contents |
|---|---|---|
| `diffusion_models/` | **203 G** | current-gen generators: flux2-klein / wan2.2 / qwen-image / z-image / ideogram (GGUF + fp8) |
| `checkpoints/` | **147 G** | SDXL / Pony / Illustrious bases — cyberrealisticPony_v180Coreshift (12.9 G), ponyRealism V22, novaAnimeXL, juggernaut/dreamshaper Lightning, lustify, hassaku, waiNSFWIllustrious, realDream + SUPIR upscalers |
| `text_encoders/` | **80 G** | qwen3-VL, qwen2.5-VL, gemma, umt5, t5-xxl, clip variants |

## Migrated in 2026-06-13 (177 G from the storetank archive)
The gen-agnostic utility set (upscalers, Florence-2 captioners, controlnet-union,
grounding-dino / SAM / yolo / depthanything / vitmatte, insightface / facerestore,
ip-adapter, CLIP-vision) **plus** the SDXL/Pony stack (bases + dmd2 / ACE++ /
character-design loras). These work alongside arbo's current FLUX.2 / WAN2.2 / qwen
generators; **comfy-dev** authors the per-model catalog entries + graphs + heroes that
turn them into usable workflows.
## Durability
- `arbo_db` (gallery/history SQLite) — backed up (restic/Backrest), local disk not NFS.
- The model tree itself is **bulk, reproducible-from-source** → not backed up; this
catalog + the migration record are the recovery map.

# Abliteration recipe — Qwen3.8-27B (MTP-aware, vision-preserving)
Captured 2026-08-19 from
[`RobinsonLabs/Qwen3.8-27B-abliterated`](https://huggingface.co/RobinsonLabs/Qwen3.8-27B-abliterated)
(base pinned at commit `1d4bf0f2`, Apache-2.0). It is the cleanest public
abliteration of the Qwen3.8-27B architecture we have found — the base family our
**gen seat** runs (see auto-memory `reference_abliteration_mtp_lessons`,
`reference_gen_qwopus_122b` lineage). This is a **reference recipe**, not a
deployed artifact: the value is the method, and specifically the two things it
gets right that most abliterations of this architecture get wrong.
Companion: `docs/pfi/model-quantization-playbook.md` owns the *quant* half of the
pipeline; this owns the *abliteration* half. When an abliteration lesson is
model-agnostic it lands here; when it is specific to one checkpoint's tensor
names it stays with that checkpoint.
## Why this architecture is the hard case
Qwen3.8-27B (`model_type: qwen3_5`, `Qwen3_5ForConditionalGeneration`) is not a
plain transformer. Abliterating it correctly means touching three surfaces a
naïve layer-loop misses:
1. **A hybrid attention trunk.** 64 language layers, most using **DeltaNet
linear attention** (`linear_attn.out_proj`), with **full attention at every
4th layer** (`self_attn.o_proj`). A refusal-direction orthogonalization that
only knows about `self_attn.o_proj` edits 16 of 64 layers and silently leaves
the model 75% un-abliterated on the attention path.
2. **A multi-token-prediction (MTP) head** (`mtp.layers.0`) used for
speculative decode. The generic 64-layer loop never reaches it.
3. **A vision tower** (`model.visual.*`, 333 tensors) that must survive
untouched or the model stops being multimodal.
## The two things this recipe gets right
### 1. The MTP head is abliterated *in-band*
This is the finding that matters most to us, because our gen seat gates on MTP
acceptance ≳40% (`reference_abliteration_mtp_lessons`).
Most abliterations orthogonalize the trunk and leave `mtp.layers.0` untouched.
The consequence is subtle and nasty: **the draft head keeps proposing
refusal-prefix tokens that the abliterated trunk then rejects, so speculative
acceptance collapses on exactly the prompts abliteration exists to fix.** You
get a model that is abliterated *and* slow, and the slowness is worst precisely
where you wanted the behaviour change.
The fix is to orthogonalize the MTP block's **two residual-write matrices**
(`self_attn.o_proj`, `mlp.down_proj`) with the *same* refusal direction as the
trunk. The MTP **glue** — `mtp.fc`, `mtp.norm`, `mtp.pre_fc_norm_*` — is left
alone, because those are norms and an input projection, **not** residual
writers. Editing them would corrupt the draft path without removing any refusal.
### 2. The vision tower is preserved byte-identical
All 333 `model.visual.*` tensors pass through unmodified — verified by direct
tensor diff (max delta `0.000000`), not asserted. An `mmproj` is published so
the vision half is actually usable, not just nominally intact.
## The edit set (131 tensors)
Single-direction weight orthogonalization, Arditi et al. style, applied to every
matrix that writes the residual stream:
| scope | tensor | count |
|---|---|---|
| `model.language_model.layers.*` (64) | `mlp.down_proj` | 64 |
| | `linear_attn.out_proj` (DeltaNet) | 48 |
| | `self_attn.o_proj` (full-attn, interval 4) | 16 |
| `mtp.layers.0` | `o_proj` + `down_proj` | 2 |
| `model.language_model` | `embed_tokens` | 1 |
| **edited total** | | **131** |
| `model.visual.*` | preserved byte-identical | 333 |
**Hard coverage gate before writing a byte:**
`o_proj(16) + linear_out(48) == 64 == num_hidden_layers`. This is the check that
catches a partial tensor-name match — the failure mode that otherwise ships a
quietly half-abliterated model that passes a smoke test and fails in the field.
Adopt this gate in any re-derivation.
## Two calibration traps specific to this base
### Refusal-direction selection
The direction was captured **twice**, from two structurally different
chat-template renderings:
- one with `enable_thinking=false`
- one with thinking on at `reasoning_effort=xhigh` (which injects an extra
system block and shifts every token position)
The two agree at **|cos| 0.96–0.99 across layers 18–45, peaking 0.9925 at layer
26** — the layer used. Two different prompt distributions converging on the same
vector is the evidence that the direction encodes *refusal semantics* rather than
*template formatting*. A single-template capture cannot distinguish the two.
> ⚠️ **Two-template agreement is a bad LAYER SELECTOR on a heavily-merged base —
> use harmful/harmless SEPARATION instead (added 2026-08-20).** On RobinsonLabs'
> stock Qwen3.8 the agreement was 0.99 and picking its peak was fine. On DavidAU's
> Cold-Fusion GAIN merge the same metric tops out at **0.62**, and its argmax
> (layer 18) is the layer with the **worst** refusal separation in the window
> (Cohen's d 5.51 vs 9.89 at the peak) — abliterating there was a measured
> behavioral **no-op**. The reason: the two renderings end in different generative
> modes (`</think>\n\n` = about to answer vs `<think>\n` = about to reason), so
> `|cos|` scores refusal *plus* mode, and on a merge the mode term dominates. The
> selector that actually predicts efficacy is **how cleanly the direction splits
> harmful from harmless prompt activations** (Cohen's d / AUC), gated on the sink
> screen (separation and sink-energy both rise with depth, so the raw peak is
> usually sink-dominated). On Cold-Fusion this picked **layer 35** (d 9.35, AUC
> 0.9997, sink 0.094%) and the abliteration worked. Keep agreement as a
> diagnostic; do not select on it. See
> `services/coldfusion-abliteration/README.md`.
### The attention-sink dimension — the one that bricks the model
**Qwen3.8-27B's massive-activation dimension is `3994`.** It carries 19–21% of
the direction's energy at layers 1–3, and orthogonalizing it out of every
residual writer produces a model that **loads, runs, and emits garbage.** Layer
26 was chosen partly because it carries only **0.06%** of its energy in dim 3994.
**Any re-derivation MUST screen for this.** It is the single most likely way to
waste a GPU afternoon on this architecture and mistake the result for a failed
abliteration when it is actually an attention-sink blowout.
## Measured behaviour (their numbers, for reference)
Base vs abliterated, same session/harness/prompts, both at Q4_K_M:
| prompt set | base | abliterated |
|---|---|---|
| in-distribution (24, from capture set) | 96% (23/24) | **8%** (2/24) |
| held-out (40, disjoint, overlap=0) | 100% (40/40) | **8%** (3/40) |
Capability axes (reasoning / code / math / factual / instruction-following /
creative-RP coherence): **no regression on any axis.** Held-out train/test split
was 416/104 with overlap 0, so the 8% held-out figure is generalization, not a
reshuffle of calibration prompts.
**Note the design point:** 8% is deliberate. Harm guardrails are **retained** —
self-harm prompts still redirect (988) rather than comply. This is a
*creative-content* abliteration shipped "at the ceiling where capability and
guardrails both survive," explicitly **not** a jailbreak. That makes it a
**milder** abliteration than our incumbent gen seat (`absolute-heresy`, ~2%
author refusals, aggressive Heretic). Adopt the *method* here; the *ceiling* is a
separate call.
## How this maps onto our pipeline
The recipe is a drop-in for the front half of the House quant pipeline:
1. Pull bf16 master to NFS (verify repo id first —
`reference_verify_hf_repo_ids_before_pull`).
2. **Baseline MTP acceptance on bf16 before any surgery** — the standing rule.
3. Orthogonalize per the edit set above; enforce the coverage gate; screen dim
3994; gate the result on **MTP acceptance ≳40%, not KL** (KL misled us once —
`reference_abliteration_mtp_lessons`).
4. Verify vision byte-identical, refusals down, PPL not blown, no catatonia.
**Measure first-token KL as a *fidelity* number** (`kl_divergence.py`,
bf16-vs-bf16, held-out prompts) — it does not replace the acceptance gate in
step 3, and it is not a pass/fail on its own. Report it **split by prompt
class**: a single averaged KL over a mixed corpus is close to meaningless,
because the metric is supposed to be large on harmful prompts and small on
benign ones. The ratio is the interesting quantity. Cold-Fusion L35 measured
**0.0211 median harmless / 0.5996 median harmful = 28.4× selectivity**, on a
stack whose self-KL noise floor is exactly 0.0.
5. NVFP4-quantize in-house (mixed W4A4 + FP8-attn/lm_head —
`model-quantization-playbook.md`). **Foot-gun the GGUF card itself flags:
the imatrix does not cover the MTP block** — so a GGUF requant path leaves
MTP uncalibrated. Our NVFP4 path must calibrate it explicitly.

# Thinking-Capable eRP Finetunes, 15–30B — Deep Research
**Compiled 2026-08-12 · Window: Feb–Aug 2026 · Weighted for spatial/state coherence · Target: RTX PRO 6000 Blackwell (sm_120), NVFP4, throughput**
---
## 0. Read this first — three findings that should change your shortlist
**1. The 24B Mistral era is over.** Everything worth running in this band now sits on one of four bases, all of which ship native thinking out of the box: **Qwen3.6-27B** (Apr 2026), **Qwen3.5-27B** (Feb 2026), **Gemma-4-31B / Gemma-4-26B-A4B** (Mar 31 2026, now **Apache 2.0**), and **arcee-ai/Trinity-Mini** (26B-A3B). Mistral has shipped *nothing* in your band in 2026 — Mistral Small 4 is a 119B-A6B MoE that absorbed the Magistral line. Magistral-Small-2509 (Sep 2025) is still the newest in-range Mistral reasoning model, and the 24B tunes built on it are now a legacy tier.
**2. The evidence says heavy eRP finetuning actively damages the thing you care about most.** This is the uncomfortable core of this report and it's covered in §2. Short version: reasoning-native models buy real long-context state tracking, but bolting RP-tuning *and* reasoning-tuning on top degrades both prose and world-modeling. The single most respected merger in the space says flatly that 24B "will struggle with details of logical/physical continuity at times — which is probably inescapable for a 24B model." **If spatial coherence is your #1 criterion, bias toward light-touch tunes on smart bases, not heavy eRP tunes.**
**3. MTP and best-in-class RP tuning are currently mutually exclusive — with exactly one escape hatch.** Every dedicated RP brand (Cydonia, Skyfall, Dark-Scarlett, MeroMero, Artemis, Magistry) sits on Mistral or Gemma bases that **have no MTP heads at all**. Only Qwen3.5/3.6-27B ships MTP in your band — and `from_pretrained` **silently drops the MTP heads during finetuning**, so almost every Qwen-based community tune has lost them too. The escape hatch is the `Native-MTP-Preserved` lineage (§5.2), which grafts the 15 MTP tensors back post-hoc, and already has NVFP4 checkpoints.
> **Also worth knowing up front:** at temp 0.8–1.2 (normal RP sampling), speculative decoding acceptance collapses to ~38–52%, and vLLM's own guidance is to disable it below 0.5. On a *shared, batched* box it is likely a net throughput **loss**. Details and the one contradicting measurement in §5.4.

**Wildcard worth a slot on your test rig:** [Gryphe/WorldSim-Opus-3.6-35B-A3B](https://huggingface.co/Gryphe/WorldSim-Opus-3.6-35B-A3B) — 35B-A3B, over your band but only ~3B active so it's cheap. It is the closest thing anyone has built to a model *designed* for the state-tracking problem: trained on three datasets that all carry full thinking traces, with reasoning persisting per-turn. The author calls it a research release whose "practical effectiveness remains uncertain."
**Actively avoid for your criterion:** [LatitudeGames/Equinox-31B](https://huggingface.co/LatitudeGames/Equinox-31B) — card states verbatim "No reasoning datasets were included during training," thinking suppressed by default. [TheDrummer/Rocinante-XL-16B-v1](https://huggingface.co/TheDrummer/Rocinante-XL-16B-v1) — user reports of degradation past 16k and noticeable decline past 20k; you can't track scene state in a window that small.
---
## 2. Does thinking actually help spatial coherence? — the evidence
This deserves its own section because the answer is **"yes for state tracking, no for prose, and only if the model was pretrained for reasoning."**
### 2.1 Thinking clearly helps long-context state tracking — for reasoning-native models
- **Fiction.liveBench** (narrative comprehension, theory of mind, chronological reasoning at length) is the single strongest datapoint. At 16k context: **QwQ-32B 83.3%** vs Gemma-3-27B 33.3% vs dolphin-Mistral-24B 25.0% — a reasoning-native 32B beating a *70B* non-reasoning model (Llama-3.3-70B, 33.3%) by 50 points. Same-model toggle: claude-3-7-sonnet thinking **83.3%** vs non-thinking **50.0%** at 16k. [[data]](https://raw.githubusercontent.com/mnismt/llms-long-context-benchmark/main/src/data/benchmark.ts) [[Epoch]](https://epoch.ai/benchmarks/fictionlivebench)
- **LongBench Pro** (8k–256k, includes consistency-checking and dialogue-tracking): thinking mode adds **+11 to +16 points** for reasoning-native models (Claude-4-Sonnet 56.07→69.87; DeepSeek-V3.2 51.67→67.82). But models *not trained* for thinking gain nothing — Llama-3.1-405B **+0.59**, Gemma-3-12B **−0.24**. Paper's own conclusion: "models without thinking training may fail to effectively leverage test-time compute." [[arXiv 2601.02872]](https://arxiv.org/html/2601.02872v1)
- **MuSR** (multi-step narrative state tracking): Ministral 3 14B Reasoning **70%** vs base **64%**; consistent +6 to +9 at every size down to 1.2B. [[BenchLM]](https://benchlm.ai/benchmarks/musr)
- **UGI "World Model"** column, same-model toggles: Qwen3-32B **21.25 → 23.80**, Qwen3-30B-A3B **13.10 → 16.67** with thinking on.
### 2.2 Thinking reliably damages prose and *destroys* instruction-following
Every same-model pair in the UGI dataset shows the `Writing` score dropping when thinking is on: Qwen3-14B **34.76 → 29.64**, Qwen3-32B 32.95 → 30.34, Qwen3-30B-A3B 30.24 → 28.54, Qwen3-8B 27.96 → 23.87. gpt-oss-20b degrades monotonically with reasoning effort — Writing **24.62 (low) → 24.50 (med) → 10.94 (high)** with repetition interrupts rising 2 → 1 → **8**.
The instruction-following collapse is the most reproducible effect in the entire dataset. `creative_writing_wc_exceeded_pct` — the share of creative tasks where the model blew the requested word limit:
| Model | Thinking off | Thinking on |
|---|---|---|
| Qwen3-14B | 1% | **99%** |
| Qwen3-32B | 0% | **100%** |
| Qwen3-30B-A3B | 10% | **99%** |
| Qwen3-8B | 4% | **100%** |
If you've ever wondered why a thinking model ignores your "keep replies to two paragraphs" instruction — that's this.
### 2.3 The warning case: bolting reasoning onto an RP finetune
`Cydonia-R1-24B-v4` vs `Cydonia-24B-v4` — same trainer, same base lineage, one reasoning-tuned:
| Metric | Cydonia-24B-v4 | Cydonia-R1-24B-v4 |
|---|---|---|
| Writing | 30.91 | **20.38** (−34% rel.) |
| World Model | 23.30 | **19.33** (−17%) |
| NatInt | 26.64 | 24.27 |
| Length error | 22% | **80%** |
| W/10 (willingness) | 7.8 | 8.2 ✓ |
Reasoning-tuning bought willingness and cost everything else, *including the world-model score*. Caveat: separate training runs, not a toggle, so recipe differences are confounded. But it's the closest analogue to "what happens when an RP finetuner adds thinking."
### 2.4 Mechanistic support for why
- **Visual vs Textual CoT diagnostic** (ACL 2026): textual chain-of-thought **degrades spatial transformation by up to 16.5%** and **multi-object tracking by 12.7%** vs direct answering, measured across GPT-5, Claude Opus 4.6, Gemini 2.5 Pro, Qwen3-VL-72B. [[pdf]](https://aclanthology.org/2026.alvr-main.1.pdf) That is *literally your criterion*, and CoT made it worse.
- **"Mind Your Step (by Step)"**: CoT reduces performance on implicit statistical learning by up to **−36.3%** absolute, framed as verbal overshadowing — narrating a scene in a scratchpad makes the model worse at *feeling* the scene. [[arXiv 2410.21333]](https://arxiv.org/html/2410.21333v4)
- **Contrary evidence worth weighing** — "Thinking in Character" found *role-aware* reasoning beats naive reasoning (CharacterBench 3.69 RAR vs 3.57 distill), but note the third term: **undirected extra thinking scored worst at 3.05**. The claim is not "reasoning helps," it's "reasoning helps only if its style is constrained to the character." [[arXiv 2506.01748]](https://arxiv.org/html/2506.01748v1)
### 2.5 And at the frontier, reasoning doesn't fix narrative consistency at all
- **NarrativeWorldBench**: frontier + reasoning models all cluster at **F1 0.78–0.81** at horizon 50 with no significant difference (p>0.13); everything loses ~0.20 F1 from h=10 to h=200. A purpose-built 8B latent world model holds **F1 ≥ 0.84 across all horizons** at ~4× lower cost. [[arXiv 2606.17391]](https://arxiv.org/html/2606.17391v1)
- **NCP-Bench** (Aug 2026) is the benchmark you were hoping existed — it explicitly scores *spatial consistency* ("character described on the bridge later appearing in a doorway"), *object state tracking* ("a raft inflated→deflated without justification"), and character knowledge leakage. Results are humbling: **GPT-5.2 survives 20 turns only 42% of the time**, near-zero survival by 100 turns, fact conflicts at 40–68% across all models. It tests no sub-32B models. [[arXiv 2608.08160]](https://arxiv.org/abs/2608.08160)
- **RP-Bench** found reasoning models (GLM 5.1, Gemini 3.1 Pro, Kimi K2.5/K2.6) *underperformed* frontier non-reasoning models on roleplay dimensions, with severe latency costs (Kimi K2.6 p95 **173s**, **17% truncation at length limit** — truncation is itself a coherence failure). Its verdict on the category: "**The RP-specialist finetunes — the models marketed for exactly this — rank last.**" [[repo]](https://github.com/LeviTheWeasel/rp-benchmark)
### 2.6 What I'd actually do with this
The defensible synthesis: **use thinking sparingly and structurally, not as an always-on prefix to prose.** A gated pattern — reasoning enabled for scene-state checks, scene transitions, and complex multi-character blocking; disabled for straight prose continuation — captures the state-tracking gain without paying the prose and length-adherence tax. Every model in §1 that supports *dual* mode (MeroMero, Artemis, BlueStar, Dark-Scarlett) lets you do this at the request level. The always-on models (Pantheon, WorldSim) do not.

## 3. Per-model breakdowns
Metadata below is from the HuggingFace API, verified individually. Download counts are trailing-30-day and are **unreliable as a quality signal** — most users pull the GGUF mirror repos, not the BF16 originals.
### 3.1 zerofata/G4-MeroMero-v2-31B — best-shaped training for your criterion
[huggingface.co/zerofata/G4-MeroMero-v2-31B](https://huggingface.co/zerofata/G4-MeroMero-v2-31B) · 31.27B · Gemma-4-31B · Apache-2.0 · **2026-08-03** · 258 dl / 43 likes
The reason this is #1: it is the **only model in the entire survey whose training explicitly optimizes reasoning against a coherence judge.** Verbatim from the card, the pipeline is `SFT > Merge > GRPO > GRPO > on-policy SFT`:
1. Diversity SFT — ~4,000 curated stories, 0.5 blend merge-back
2. **Creative GRPO** — 8 rollouts/prompt, 300 steps, *thinking disabled*
3. **RP Logic GRPO** — 100 steps, *thinking enabled*, scored by "a logic-defect judge (DeepSeek-V4 Flash with a rubric)", with a `reward_judge_coherence` reward term
4. On-policy SFT — ~3,300 self-generated RP samples, diversity-filtered
Stage 3 is the mechanism that should produce state tracking. **Honest caveat:** the card does *not* claim improved spatial coherence as an outcome, and I could not confirm the stage-3 prompts were multi-turn (an earlier source claimed this; it's unverified). You're buying a plausible training signal, not a measured result.
Author's own metrics vs stock Gemma 4: swipe diversity **0.72 vs 0.43**, story slop **7.4 vs 8.8 per 1k words**, bare-prompt attractor hit rate **66% vs 99%**, no regression on IFEval / GSM8K / MMLU-Pro.
- **Thinking:** dual, via `Gemma4-Think.json` / `Gemma4-NoThink.json` SillyTavern presets. Reasoning is longer than stock Gemma 4, shorter than MeroMero v1.
- **Samplers:** temp 0.8–1.0, MinP 0.05
- **Quants:** GGUF (official + mradermacher), FP8 W8A16 ([hoborific](https://huggingface.co/hoborific/G4-MeroMero-v2-31B-W8A16-FP8)), exl3, MLX. **NVFP4 exists only for v1** ([pekkAi](https://huggingface.co/pekkAi/G4-MeroMero-31B-NVFP4), [heretic variant](https://huggingface.co/pekkAi/G4-MeroMero-31B-uncensored-heretic-NVFP4)). You'll quantize v2 yourself.
- **Note:** 31.27B is marginally over your stated band. There is a true in-band sibling, [G4-MeroMero-26B-A4B](https://huggingface.co/zerofata/G4-MeroMero-26B-A4B) (25.8B MoE, A4B, May 2), which *does* have NVFP4 ([Deaquay](https://huggingface.co/Deaquay/G4-MeroMero-26B-A4B-NVFP4), [pekkAi heretic](https://huggingface.co/pekkAi/G4-MeroMero-26B-A4B-it-uncensored-heretic-NVFP4)) and claims "reasoning is more structured, using less tokens during RP." But the 26B's card is candid that "logic and repetition I think are roughly on par with the original" — v2-31B is where the coherence work actually happened.
### 3.2 Gryphe/Pantheon-Reasoning-27B — best methodology, and it sits on the MTP-preserved base
[huggingface.co/Gryphe/Pantheon-Reasoning-27B](https://huggingface.co/Gryphe/Pantheon-Reasoning-27B) · ~27.8B · Apache-2.0 · **2026-05-30** · 232 dl / 27 likes
Base is `llmfan46/Qwen3.6-27B-uncensored-heretic-v2-Native-MTP-Preserved` — **verified**, and that matters enormously for your rig (§5.2).
Two things make this the most methodologically interesting tune in the set:
- **Always-on reasoning.** Verbatim: "The model was trained with `preserve_thinking: true`, so thinking tags remain active across all assistant turns in multi-turn conversations, not just the first." Almost every other model reasons once and then stops.
- **The thinking traces were generated as *planning*, not annotation.** DeepSeek 3.2 produced them under the instruction to "think as a writer planning their next response — before writing — rather than annotating a response," then judge-model validated. This is the "role-aware reasoning" pattern that the CharacterBench work found is the *only* kind that helps.
Data mix: Pantheon RP corpus ~28%, Opus-4.6-Reasoning-24k ~21%, WorldSim narrative ~16%, text adventure/IF ~16%, general RP ~16%, Tiamat ~3%.
- **Samplers:** temp 1.0, **rep_pen 1.0**, min_p 0.05. The rep-pen point is emphatic and now consensus among reasoning-RP authors: repetition penalties corrupt thinking content. **Any thinking model whose card recommends rep_pen > 1.0 is a red flag.**
- **Template:** ChatML (Qwen3.6 chat template)
- **Author's own framing:** a research release, with the stated open question being "does reasoning actually help roleplay, or does it just add latency?" Respect that honesty.
- **Quants:** GGUF only. No NVFP4, no FP8. You will quantize this one.
- **Sibling:** [Pantheon-Reasoning-26B-A4B-1.1](https://huggingface.co/Gryphe/Pantheon-Reasoning-26B-A4B-1.1) (26.5B MoE, Gemma-4-26B-A4B, Jun 8) — same methodology, stricter trace QA, genuinely in-band, and the **most-reused merge donor in the whole 26B-A4B ecosystem**. SillyTavern gotcha: character-name prefixes break reasoning compatibility on this one — disable them.
### 3.3 llmfan46 Native-MTP-Preserved (NVFP4) — the throughput play
[huggingface.co/llmfan46/Qwen3.6-27B-uncensored-heretic-v2-Native-MTP-Preserved-NVFP4](https://huggingface.co/llmfan46/Qwen3.6-27B-uncensored-heretic-v2-Native-MTP-Preserved-NVFP4)
Not an RP finetune — a decensored Qwen3.6-27B. It's on this list because it's the **only 15–30B option that is simultaneously NVFP4, MTP-intact, and uncensored**, and because §2 argues that a smart, lightly-touched base may outperform a heavy eRP tune on exactly the axis you're prioritizing.
Parent repo: 7,580 dl / 41 likes, created May 6, modified May 25. Made with Heretic v1.3.0 using a variant of Magnitude-Preserving Orthogonal Ablation (MPOA), ablating only `attn.o_proj`, `attn.out_proj`, `mlp.down_proj`. Claimed: **94% fewer refusals (6/100 vs 92/100) at 0.0021 KL divergence**, MMLU 85.67% vs 86.65% original.
The load-bearing detail is `model-auxiliary.safetensors` in the repo — that's where Qwen stores the MTP heads, and its presence is hard proof the claim isn't marketing. The card enumerates all 15 preserved tensors.
**Pair it with a style fix.** Its weakness vs a proper RP tune is voice, not intelligence. [Gryphe/Gemma-4-26B-A4B-StyleTune-V2](https://huggingface.co/Gryphe/Gemma-4-26B-A4B-StyleTune-V2) demonstrates the approach on the Gemma side and is the most quantitatively-supported claim in this whole survey: it trains **precisely one tensor** — "the `lm_head` output projection… freeze everything else. All 30 transformer layers, all the attention heads, all the MLPs — completely untouched" — and measures **52% fewer clichés per 100 words (1.141 → 0.551)** over 200 RP prompts with only 19.9% shared trigram vocabulary. Reasoning capability is untouched by construction. There's no Qwen equivalent published yet, but the recipe is simple enough to replicate.
### 3.4 allura-org/Qwen3.5-27B-Anko
[huggingface.co/allura-org/Qwen3.5-27B-Anko](https://huggingface.co/allura-org/Qwen3.5-27B-Anko) · ~27.4B · Apache-2.0 · **2026-04-08** · 40 dl / 11 likes
**Correction to circulating claims:** the base is **`ArliAI/Qwen3.5-27B-Derestricted`**, not stock Qwen3.5-27B. LoRA r=64 / α=512 on Doubao Seed 2.0 Pro reasoning traces, trained on both reasoning *and* non-reasoning responses, so it's dual-mode by construction. Stated goal, verbatim: "increase the quality of reasoning and decrease looping, and fix slop in outputs."
Why it ranks well for you: Qwen3.5-27B is the best state-tracking base in the band by measurement — **MuSR 95, the best open-weight score overall**, and LongBench v2 60.6%.
- **Samplers, verbatim and shouted:** "**DO NOT USE QWEN'S SAMPLERS. THEY ARE AWFUL.**" Use **temp 1.25, min_p 0.05–0.1**.
- **Odd but documented:** recommended system prompt is `You are Claude, a helpful and harmless language model created by Anthropic.` It was trained to work with Claude-style system prompt formatting.
- **Quants:** GGUF only (bartowski, mradermacher). No NVFP4/FP8/AWQ/exl3.
- **Warning:** ArliAI's Derestricted line **drops MTP** — I verified the file manifest, there is no `model-auxiliary.safetensors`. So Anko has no MTP.
### 3.5 ReadyArt/Dark-Scarlett-v1.0-27B — cleanest eRP with flag-based thinking
[huggingface.co/ReadyArt/Dark-Scarlett-v1.0-27B](https://huggingface.co/ReadyArt/Dark-Scarlett-v1.0-27B) · ~27.8B · Qwen3.6-27B · Apache-2.0 (personal use, 18+) · **2026-06-16**
The most explicitly eRP-targeted model here with a properly documented thinking toggle:
```
chat_template_kwargs: {"enable_thinking": true, "reasoning_effort": "medium"}
```
That `reasoning_effort` knob is unusually useful for the gated-thinking pattern in §2.6 — you can dial it per-request rather than binary on/off.
Training: LoRA r=32, 2 epochs, **text layers only**, on 12,211 curated adult-RP prompts, with multi-turn generation, refusal filtering, and group-chat support in the pipeline.
- **Samplers:** top_p 0.92, temp 1.0, freq_pen 0, pres_pen 0
- **Real limitation:** the card states it's optimized for Male(user)→Female(AI) perspective. Narrow.
- **Quants:** GGUF + ReadyArt's own W4A16/W8A16 PTQ. **No NVFP4, no FP8.**
- Family context: ReadyArt shipped a dense June burst — `Dark-Scarlett-v2.0-31B` (Gemma-4), `v1.0-26B-A4B`, `v1.0-31B`, `v0.4-2509-24B`, `Heimdallr-v0.02-31B`. Download signal favors the MoEs.
### 3.6 TheDrummer/Artemis-31B-v1.1 — freshest, longest bake
[huggingface.co/TheDrummer/Artemis-31B-v1.1](https://huggingface.co/TheDrummer/Artemis-31B-v1.1) · 31.27B · Gemma-4-31B · **2026-08-06** · 7 likes · **no license set**
Four months of public iteration through BeaverAI test builds (`v1a` Apr 8 → `v1n` Jul 22), which is unusually thorough for this scene. **Use v1.1, not v1** — v1 has "strong writing potential but requires manual adjustments"; v1.1 "improves stability while maintaining v1's creative strengths," specifically fixing **"dash spiraling."**
- **Thinking:** the most flexible activation of any model here — "standard thinking gemma template or `<thinking></thinking>` blocks on non-thinking gemma template," and "`<think></think>` should work too, along with tricks like `<evil_think></evil_think>`."
- **Samplers:** not fixed in the card; Drummer points to a crowdsourced sampler spreadsheet.
- **Too new for consensus** as of Aug 12 — one enthusiastic but content-free feedback thread.
- Predecessor if you want something proven: [Skyfall-31B-v4.2](https://huggingface.co/TheDrummer/Skyfall-31B-v4.2) (Apr 3, Magistral-Small-2509 upscaled, Mistral v7 Tekken template) is the established workhorse of this window and **has an NVFP4 quant already** ([ealexeev, v4.1](https://huggingface.co/ealexeev/TheDrummer-Skyfall-31B-v4.1-NVFP4)).
### 3.7 sophosympatheia/Magistry-24B-v1.1 — the honest one
[huggingface.co/sophosympatheia/Magistry-24B-v1.1](https://huggingface.co/sophosympatheia/Magistry-24B-v1.1) · 23.6B · Apache-2.0 · **2026-03-22** · 35 likes (highest like count in-band)
A mergekit DELLA merge (not a finetune) on `Darkhn/Magistral-2509-24B-Text-Only`, so it inherits Magistral's native reasoning. Donors: `Casual-Autopsy/Maginum-Cydoms-24B`, `DarkArtsForge/Magistaroth-24B-v1`, plus `Huihui-Devstral-Small-2-24B-Instruct-2512-abliterated` at 0.3.
I'm listing it partly because its card contains the **single most on-point statement anyone in this scene has made about your criterion**, verbatim:
> "This model is fun, but it will struggle with details of logical/physical continuity at times — which is probably inescapable for a 24B model."
That is a respected merger saying 24B sits below the threshold where physical continuity holds. Take it seriously as a floor: **if spatial coherence is your top priority, 27B+ is the entry point, not 24B.**
- **Thinking:** prefill-based — force the reply to start with `<think>` plus basic instructions. Card notes `<think></think>` works better than Mistral's `[THINK][/THINK]` tags. (Related gotcha: on Mistral models `<think>` is *not* a special token; `[THINK]` is.)
- **Samplers:** three named presets — Conservative (temp 0.7, MinP 0.05, Top-N σ 0.75), Balanced (temp 1.0, Adaptive-P target 0.6 / decay 0.9), Wild (temp 0.9, Adaptive-P target 0.35 / decay 0.45). Also ships a SillyTavern Master Import JSON.
- **It is NOT gated** (a claim to the contrary is circulating; the API says `gated: false`).
- **Quants:** GGUF, exl3, MLX MXFP4/MXFP8. **No NVFP4.**
### 3.8 zerofata/Q3.5-BlueStar-v2-27B — best-documented anti-slop SFT
[huggingface.co/zerofata/Q3.5-BlueStar-v2-27B](https://huggingface.co/zerofata/Q3.5-BlueStar-v2-27B) · ~27.4B · Qwen3.5-27B · **MIT** · **2026-03-20** · 42 likes
The interesting technical contribution here is **custom loss masking on slop phrases** — "most common phrases of slop are masked out, so the model doesn't get rewarded for learning these patterns." That lets you train on otherwise-useful RP data without absorbing its clichés. SFT ~27M tokens via Axolotl + LoRA on 4×H200.
- **Thinking:** prefill `<think>\n` — and importantly, "it is required to prefill the `<think>\n` **as that is how it was trained**." This is a trained-for prefill, not a bolted-on hack. Ships separate think/no-think ChatML instruct JSONs.
- **Samplers:** temp 0.8–1.0, MinP 0.05–0.075
- **⚠️ Trained at 10,756 token sequence length** despite the 262k base. See §4 on why this matters more than anything else in the card.
- **Quants:** GGUF. The two "NVFP4" BlueStar repos you'll find are **MLX** (Apple silicon) — useless on Blackwell.
### 3.9 Also verified, lower priority
- **[Vortex5/G4-Moonlight-Dusk-26B-A4B](https://huggingface.co/Vortex5/G4-Moonlight-Dusk-26B-A4B)** (26.5B MoE, Jul 14, 1016 dl) — merge of Animus-V14.1-FFT + G4-MeroMero-26B-A4B + Esmeralda + **Pantheon-Reasoning-26B-A4B-1.1**. Highest download count of the Gemma-4 MoE merges. Thinking activation is **undocumented** — merge card only, no sampler guidance. Good candidate, poor paperwork.
- **[ArliAI/Qwen3.5-27B-RpRMax-v1](https://huggingface.co/ArliAI/Qwen3.5-27B-RpRMax-v1)** (Apr 28) — successor to the well-regarded QwQ-32B-ArliAI-RpR line, in a collection literally titled "Thinking-trained RP specialized models." **Confirmed to have no model card at all** — training method, datasets, template, samplers, context all unverified. Heavy third-party GGUF activity (bartowski et al.) suggests real pickup. High risk, possibly high reward.
- **[NewEden/Trinity-Mini-Ichthyo](https://huggingface.co/NewEden/Trinity-Mini-Ichthyo)** (26.1B-A3B, Jul 10, 2,489 dl — highest of any in-band RP repo) — trained with **actual RL** (Prime RL run, step-100 checkpoint, 32,768 ctx). Base is `NewEden/Trinity-Mini-Futaba`, not stock Trinity-Mini. **Gated behind a contact-info agreement and the README returns 401** — I could read nothing. Zero third-party quants, consistent with the gating. Interesting, unassessable.
- **[Nimbz/Gemma-4-Gembrain-31B](https://huggingface.co/Nimbz/Gemma-4-Gembrain-31B)** (~Aug 2) — 5-phase Gemma-4 merge, `<|think|>` reasoning, targets "enhanced logical and lateral thinking." Samplers: temp 1.0, Top-P 0.95, Min-P 0.03, DRY 0.8/1.75. Trending but unproven.
- **[ReadyArt/gemma-4-31B-it-scotoma-2](https://huggingface.co/ReadyArt/gemma-4-31B-it-scotoma-2)** (Aug 6) — not an RP tune, the most rigorous **anti-slop** work of the window: γ-fold refusal-edit projection + 3 rounds of preference training on 9.3k pairs. Measured over 480 RP continuations: stacked adjectives **↓21×**, "Not X. But Y." **↓4×**, em-dash asides **↓4×**. ⚠️ Explicitly **"not uncensored"** — refusal behavior matches base. Useful as a merge donor or style reference, not as a driver.
### 3.10 Confirmed dormant — stop waiting on these
Checked directly; **no 2026 releases in this band**: **anthracite-org / Magnum** (last: Nov 2024) · **Sao10K** (Mar 2025) · **Nitral-AI** (Sep 2025) · **PocketDoc / Dans-PersonalityEngine** (May 2025) · **Undi95** (Mar 2025) · **aixonlab** (May 2025) · **knifeayumu** (Aug 2025) · **TareksLab** (70B only, Aug 2025) · **Doctor-Shotgun** (quant-only in 2026) · **Delta-Vector** (moved to 399B Trinity-Large) · **inflatebot** · **Tesslate** (never RP).
**Steelskull correction:** `Steelskull/CWT-V5.6` (Apr 2026) is **not** an RP model — it's "Cognitive Workspace Transformer," a **57.8M-parameter** from-scratch research architecture trained on FineWeb-Edu. Steelskull's RP line (Electra / Nevoria / Broken-Tutu) has shipped nothing since L3.3-Shakudo-70B in Jul 2025.
**One to watch:** `TheDrummer/Orion-26B-A4B` exists only as BeaverAI test builds (`v1a` May 24 → `v1c` Jul 10). Dead center of your band. Likely the next official release after Artemis.

## 4. The thing nobody puts in the headline: training context length
This is buried in the model cards and it undercuts a lot of the spatial-coherence story:
| Model | Base context | **Actually trained at** |
|---|---|---|
| Q3.5-BlueStar-v2-27B | 262k | **10,756 tokens** |
| MS3.2-PaintedFantasy-v4.1-24B | 128k | **10,756 tokens** |
| Trinity-Mini-Futaba | 128k | **32,768 tokens** |
| Rocinante-XL-16B-v1 | — | user reports drift past **16–20k** |
You cannot track scene state across a 60k-token roleplay with a model whose RP behavior was only ever reinforced at 10k. Base-model long-context ability degrades gracefully in benchmarks, but the *RP-specific* behavior these tunes install has a much shorter effective horizon. **When you evaluate, test at your real session length, not at 8k.** This is probably the highest-leverage thing in this report that no leaderboard captures.
Related: **Gemma-4 degrades far more gracefully with context than Qwen3.6** on throughput — 32k→128k loss of **−32%** vs Qwen3.6-35B-A3B's **−65%** (dual RTX 4070 Ti). That's throughput only, not accuracy, but it's consistent with the architecture: Gemma-4 is full-attention dense; Qwen3.5/3.6 are hybrid Gated-DeltaNet linear-attention designs (3 linear blocks per 1 full-attention block), which are theoretically weaker at exact long-range state tracking despite the bigger advertised window.

## 5. Deployment on your rig
### 5.1 NVFP4 on sm_120 — the headline is W4A16, not W4A4
**Do not ship plain W4A4 NVFP4 for long-context RP.** NVIDIA's own guidance flipped to recommending **W4A16 (`NVFP4A16`)** for sm_120/121, citing **KLD 2–4× worse for W4A4, "especially past ~10K context where activation quantization noise compounds with KV-cache lookups."** [[NVIDIA forum]](https://forums.developer.nvidia.com/t/update-for-nvfp4-model-conversion-to-use-w4a16-instead-of-w4a4/370403) That is precisely the failure mode you'd care about and it's the only source I found measuring KLD rather than MMLU at RP-relevant context lengths.
Cheap experiment: **NVFP4 weight storage is identical between W4A4 and W4A16** — only the activation scales differ. Flipping is a `config.json` patch (set `config_groups.group_0.input_activations` to `null`), not a re-quantization.
**The tension you should be aware of:** W4A16 gives up the FP4 tensor-core compute path, so the gain becomes pure weight-compression/bandwidth — and Benjamin Marie's comparison found NVFP4A16 shows *minimal throughput gain over INT4 AWQ*, with AWQ/AutoRound scoring slightly *better* on accuracy and ~7GB smaller on disk. The counterargument for your box: freed VRAM converts to KV cache, which converts to concurrency, which is what you actually want on a shared rig.
**Quality at 24–32B — the size gradient is real.** Red Hat's aggregate NVFP4 recovery: 70B–235B ~99%, **~30B 97–99%**, 7B–14B ~95–98%. Per-model, the damage concentrates in reasoning: Qwen3-32B-NVFP4 scores 99.83% OpenLLM v1 but only **94.21% reasoning avg**; Qwen3-14B drops to **91.45% reasoning, 86.34% on AIME24**. NVIDIA's own QAD report states it plainly: *"for small LLMs, the accuracy drop from PTQ is often non-negligible."*
**sm_120-specific caveats (all confirmed against upstream issues):**
- **Silent Marlin fallback.** Backend selectors check `is_device_capability(100)` only; sm_120 fails and falls back to Marlin dequant, logging *"Your GPU does not have native support for FP4 computation."* [vLLM #47749](https://github.com/vllm-project/vllm/issues/47749) was **still open as of Jul 6 2026**. **Always grep your startup log for that warning** — if it's there, the whole exercise is moot.
- **Dense is the healthy path.** [CUTLASS #3096](https://github.com/NVIDIA/cutlass/issues/3096) explicitly states dense FP4 GEMM works correctly on sm_120; the broken path was **grouped (MoE) GEMM**. Nearly every sm_120 NVFP4 horror story you'll read is a MoE story. This is a real argument for **dense 27B over 26B-A4B MoE** on your hardware, at least until the FlashInfer 0.6.5 / `compute_120f` path is more settled.
- `compute_120f` (needs **CUDA 13.0**) vs `compute_120a`: ~2.7× throughput difference (39.0 vs 14.6 tok/s in the CUTLASS issue's own table).
- `flashinfer_cutlass` has a reported **race condition causing silent memory corruption at high concurrency**; `flashinfer_cudnn` is reported safer. **Directly relevant to you as a multi-tenant operator** — toy prompts won't surface it, only soak testing will.
- FP8 KV cache is not universally safe on sm_120 (GLM-5 requires BF16 KV). Test yours.
Env vars people actually set:
```bash
export FLASHINFER_CUDA_ARCH_LIST=12.0f
export FLASHINFER_FORCE_SM=120f
export VLLM_NVFP4_GEMM_BACKEND=cutlass
```
**Toolchain choice matters more than it looks:** llm-compressor emits `compressed-tensors` but **does not calibrate KV-cache scales by default**, so you fall back to BF16 KV — **2× KV memory, roughly half the concurrent sessions.** ModelOpt emits per-layer `k_scale`/`v_scale` and gets you real FP8 KV. On a shared box that's the deciding factor.
### 5.2 MTP — the one lineage that keeps it
The failure chain is three-deep and every stage is silent:
1. **Loading.** `Qwen3_5ForConditionalGeneration.from_pretrained` **drops the MTP heads**. Finetune → `save_pretrained` → heads gone, no warning. I verified ArliAI's Derestricted and RpRMax file manifests: **no `model-auxiliary.safetensors`, no MTP tensors.** This is why almost no community Qwen tune has MTP.
2. **Quantization.** Converters use allowlists and skip unknown tensor prefixes silently; GPTQ-style quantizers preserve the weights but never calibrate them, leaving effectively random values.
3. **Serving.** Even when present, `mtp.*` / `mtp.fc` must be in `quantization_config.ignore` or vLLM runs a quantized MTP head against differently-scaled activations.
**The fix is unglamorous:** copy the 15 MTP tensors out of the original `Qwen/Qwen3.6-27B` checkpoint and graft them onto your output shard. Published pipelines: [lna-lab/GGUF-to-NVFP4-SM120](https://github.com/lna-lab/GGUF-to-NVFP4-SM120) and AEON-7's variant. **This means you can graft MTP back onto Pantheon-Reasoning-27B**, since it descends from an MTP-preserved base — probably the single highest-value move available to you.
**Two caveats on grafted MTP for eRP specifically:**
- You're bolting the *base* model's draft head onto a *finetuned* target. Acceptance drops by however much your finetune moved the distribution — for an RP tune, a lot.
- The rtx6kpro notes warn explicitly: **"abliterated models: MTP heads were trained on censored content; avoid with abliterated models."** The head predicts what the *aligned* model would say, so acceptance collapses precisely on the content that differs. Mechanism is sound; generality is my inference.
- They also measured MTP causing a **−22% throughput regression** on sm_120 when Marlin fallback was active, because the draft heads expect native FP4 activations.
### 5.3 Existing NVFP4 checkpoints of RP finetunes — more than you'd expect
Two quantizers specialize in exactly this:
- **[ealexeev](https://huggingface.co/ealexeev)** — a pure TheDrummer shop, 9 repos, **ships `recipe.yaml` in-repo** so the recipe is reproducible: [Skyfall-31B-v4.1](https://huggingface.co/ealexeev/TheDrummer-Skyfall-31B-v4.1-NVFP4), [Cydonia-24B-v4.3](https://huggingface.co/ealexeev/TheDrummer-Cydonia-24B-v4.3-NVFP4), [Snowpiercer-15B-v4](https://huggingface.co/ealexeev/TheDrummer-Snowpiercer-15B-v4-NVFP4), [Magidonia-24B-v4.2.0](https://huggingface.co/ealexeev/The-Drummer-Magidonia-24B-v4.2.0-NVFP4)
- **[Firworks](https://huggingface.co/Firworks)** — ~100 NVFP4 repos incl. [Cydonia-24B-v4.3-heretic](https://huggingface.co/Firworks/Cydonia-24B-v4.3-heretic-nvfp4), [Magidonia-24B-v4.3](https://huggingface.co/Firworks/Magidonia-24B-v4.3-nvfp4), [WeirdCompound-v1.7-24b](https://huggingface.co/Firworks/WeirdCompound-v1.7-24b-nvfp4)
- **[AEON-7](https://huggingface.co/AEON-7)** — the MTP-grafting specialists. ModelOpt 0.43.0, `NVFP4_DEFAULT_CFG`, 15 MTP tensors grafted post-quantization, GatedDeltaNet layers kept BF16 (432 keys across 48 GDN layers), calibrated on `neuralmagic/calibration` 20 samples × 8192 tokens. **Publishes an RTX PRO 6000 number: 92 tok/s median, 124.7 peak, 67.7% acceptance.**
- **[sakamakismile](https://huggingface.co/sakamakismile)** — highest volume (~57 repos), explicit `-MTP` naming convention, incl. actual creative tunes: [Carnice-V2-27b-NVFP4-TEXT-MTP](https://huggingface.co/sakamakismile/Carnice-V2-27b-NVFP4-TEXT-MTP), [Qwen3.6-27B-Fable-Fusion-MTP-NVFP4](https://huggingface.co/sakamakismile/Qwen3.6-27B-Fable-Fusion-MTP-NVFP4). Also ships `DSv4-Flash-FP8-SM120-Configs`.
**Gemma-4 NVFP4 works** — the catastrophic vLLM bug ([#39407](https://github.com/vllm-project/vllm/issues/39407), logits saturating at the bf16 softcap ceiling and emitting `" a a a a"` forever) is in the **FP8_BLOCK** path, not NVFP4. Existing Gemma-4-*finetune* NVFP4 checkpoints: [pekkAi/G4-MeroMero-31B-NVFP4](https://huggingface.co/pekkAi/G4-MeroMero-31B-NVFP4), [AEON-7/Gemma-4-31B-it-DECKARD-HERETIC-Uncensored-NVFP4](https://huggingface.co/AEON-7/Gemma-4-31B-it-DECKARD-HERETIC-Uncensored-NVFP4), [Deaquay/G4-MeroMero-26B-A4B-NVFP4](https://huggingface.co/Deaquay/G4-MeroMero-26B-A4B-NVFP4). Gemma-4 quirks: exclude vision tower / `embed_vision` / `multi_modal_projector`, and note heterogeneous attention head dims (`head_dim=256`, `global_head_dim=512`) need multi-group KV support if you use spec decode. Gemma-4 has **no MTP** — spec decode there is EAGLE-based.
### 5.4 Speculative decoding at RP temperatures — probably don't
Measured acceptance vs temperature [[DigitalOcean vLLM guide]](https://www.digitalocean.com/community/tutorials/speculative-decoding-vllm-configuration-guide):
| Temperature | Acceptance |
|---|---|
| 0.0 | ~81% |
| 0.4 | ~71% |
| **0.8** | **~52%** |
| **1.0** | **~38%** |
The stated rule: below 0.5 acceptance, spec decode is net-negative. **Your RP sampling sits at 0.8–1.25.**
Corroborating, from AEON-7's own Qwen3.5-27B NVFP4 card with a DFlash drafter: greedy **~80% acceptance → ~91 tok/s**; **sampled ~5% acceptance → ~38 tok/s** against a ~50 tok/s no-spec baseline. That's a **~24% throughput loss** from turning it on.
And batching compounds it: spec decode gives 1.5–2.8× at low QPS but **1.4–1.8× slowdown at high QPS** when the GPU is compute-saturated. Every impressive DFlash/EAGLE number you'll see quoted is greedy decoding at concurrency 1 — the exact opposite of your regime on both axes.
**One contradicting measurement worth replicating:** [loFT LLC](https://loftllc.dev/en/docs/tech/llm-research/qwen3-6-27b-nvfp4-mtp-vllm-benchmark/) reports Qwen3.6-27B NVFP4 + MTP=3 at **87.9% acceptance, accept length 3.64, 161 tok/s mean at temp 1.0, top_p 0.95, top_k 20** on 2× RTX PRO 6000 Max-Q. If true, native MTP heads degrade far more gracefully under sampling than external drafters do — which would be a meaningfully different conclusion. Verify before believing it.
If you do use spec decode, vLLM ships [Dynamic Speculative Decoding](https://docs.vllm.ai/en/latest/features/speculative_decoding/dynamic_speculative_decoding/) to auto-disable under load — but note [vLLM #25112](https://github.com/vllm-project/vllm/issues/25112): *"Spec decoding is not disabled at/after configured batch size."* Verify the disable actually fires.
Free alternative worth trying: **n-gram / prompt-lookup decoding**. RP genuinely echoes its input — character cards, world info, prior turns get re-quoted — so it may pick up real acceptance at zero VRAM cost. Set `prompt_lookup_min=8`; the default of 2 causes structured-output corruption on Qwen3-class models ([vLLM #40875](https://github.com/vllm-project/vllm/issues/40875)).
### 5.5 Throughput reference points (all single RTX PRO 6000 unless noted)
| Model | Precision | Single-stream | Batched |
|---|---|---|---|
| Gemma-4-31B | NVFP4 + FP8 KV | 40.7 tok/s @1k, 38.3 @128k | 126.0 @ 4 req |
| Qwen3.6-27B | FP8 | 46.1 @1k, 30.4 @256k | peak 189.3 @ 5 concurrent |
| Qwen3.6-27B | NVFP4, 256k ctx, FP8 KV | ~58 tok/s | ~119 @ 2-parallel; 64.8 GiB left for KV |
| Qwen3.6-27B | NVFP4 + grafted MTP=3 | median ~92, peak 124.7 | 67.7% acceptance |
| Qwen3-32B | NVFP4 vs BF16 | — | **2,050 tok/s @ conc 128** (vs 1,156 BF16 = 1.77×) |
Note the NVFP4-over-BF16 advantage **narrows** from 2.1× at conc 64 to 1.77× at conc 128 — consistent with the argument that NVFP4's dense-model gain is weight compression (bandwidth), not FP4 math. For your throughput-first shared box: NVFP4 buys less raw compute than marketed, but a lot of freed VRAM → KV cache → concurrency.
### 5.6 A starting stack
```bash
pip install -U llmcompressor==0.13.0 # released 2026-08-11
# Recipe changes that matter for RP:
# scheme="NVFP4A16" (weight-only, NOT plain "NVFP4")

# num_calibration_samples=256-512, max_seq_length=8192
#
# UltraChat calibration is assistant-y and sanitized — RP finetune activations
# are out-of-distribution relative to it. The one published NVFP4 RP quant used
# 64 samples of Opus-WritingPrompts at seq len 8192. Long sequences matter more
# than sample count here.
#
# Cost on your card: ~45-60 min for a 27B; GPU-trivial (layers onloaded one at

**Validation gates before you trust any of it:**
1. `grep` the startup log for `"does not have native support for FP4"` → if present you're silently on Marlin.
2. **KLD against the BF16 parent at 16k and 32k context**, not MMLU. This is the only test that catches the failure mode you care about.
3. If spec decode is on, log `draft_acceptance_rate` **at production temperature**. Below 0.5, turn it off.
4. Soak-test at real concurrency — the `flashinfer_cutlass` corruption is silent and load-dependent.

## 6. How I'd actually evaluate these
Nobody publishes spatial-coherence numbers for these models. Across the entire survey the only quantitative claims that exist are Gryphe's StyleTune slop metrics and zerofata's swipe-diversity numbers. **You will have to measure this yourself**, and it's not hard:
Build ~20 adversarial scenes that bait the specific failures you care about, run each model 5× per scene at your production sampler settings, and score:
- **Position tracking** — 3+ characters in a room, someone moves, someone leaves. Does the model place them correctly 10 turns later?
- **Clothing/object state** — an item is removed, moved, or destroyed. Does it reappear?
- **Anatomy/limb count** — the classic failure. Score explicit impossibilities.
- **Knowledge partition** — character A learns something in private. Does character B act on it? (OmniToM found "Knowledge Access" is the weakest dimension across all models at 56–75% macro-F1 — this is a real, measurable, near-universal weakness.)
- **Context depth** — run every test at 8k, 32k, and your real session length. Per §4, this is where the tunes will separate, and where none of them are trained.
- **Thinking on vs off, same seed, same scene.** Given §2, this is the highest-information single comparison you can run, and no published benchmark has done it for RP.
RP-Bench's own validation is a useful warning about scoring: LLM-judge methods showed **negative correlation** with community Bayesian Elo (ρ between −0.31 and −0.07), and its automated "Flaw Hunter" disagreed with human users more often than it agreed (50.7% vs 38.7%). **Use rule-based checks for state tracking** (did the model say "left hand" when the character's left arm was established as pinned?) rather than asking an LLM judge whether the scene was coherent.
---
## 7. What I could not verify
Stated plainly so you can weigh the rest:
- **Reddit is hard-blocked by this environment's egress policy** (403 on `reddit.com`, `old.reddit.com`, the JSON API, and domain-filtered search). The r/SillyTavernAI weekly megathreads are the single best source for practitioner reports on spatial coherence, and I got none of it. Everything here comes from HuggingFace, benchmark sites, papers, and blog coverage. **The community-consensus layer of this report is missing** — treat the rankings as evidence-based rather than user-validated.
- **No model card in this survey makes an affirmative spatial-coherence or state-tracking claim.** I checked all of them explicitly. What exists is MeroMero-v2's training-side coherence judge, and Magistry's *disclaimer*. Any source telling you these models advertise state tracking is fabricating.
- **Trinity-Mini-Ichthyo's card is unreadable** (gated, 401). It has the highest download count in-band and I can tell you nothing about it.
- **Artemis-31B-v1.1 has no license set** — no tag in the API, nothing in the README. Matters if this is going anywhere commercial.
- **The Qwen-27B-family exact parameter counts** were inconsistent across API calls (27,781,427,952 / 27,781,419,504 / 27,356,728,560 in mutually contradictory slots). The ~27.4B / ~27.8B magnitudes are safe; exact digits are not.
- **MeroMero-v2 stage 3 being "multi-turn"** — steps, thinking-enabled, and the DeepSeek-V4-Flash logic-defect judge are all confirmed verbatim; the multi-turn detail is not.
- **`heretic` does not preserve MTP natively.** I checked PyPI, GitHub, and the docs for any mention of MTP, auxiliary weights, or draft heads — absent from all three. The `Native-MTP-Preserved` repos are doing a manual post-hoc graft the tool doesn't do for you. Whether heretic 1.4.0 (Jun 2026) added passthrough is unverified.
- **UGI Leaderboard's live 2026 data** — the CSV is 653kB and only the first chunk is fetchable; the visible slice runs to Nov 2025. The 2026 entries (`Huihui-Qwen3-VL-32B-Thinking`, `Ayla-Light-v2`) are unverified.
- **EQ-Bench carries essentially no 15–32B RP finetunes** — only 9–12B Gemma derivatives. There is no Cydonia/MeroMero/Pantheon Elo, so cross-referencing UGI willingness against EQ-Bench writing quality is not currently possible for any model in this report.
- `arxiv.org/html/2607.22732` ("Spatial Reasoning in LLM Game Agents: Impact of Causal Context and Multi-Step Planning") — rate-limited on 6 attempts. Likely the single most on-point paper for your question. Worth retrying.

# Gemma-4 26B-A4B ERP/RP tune — GPU sizing adjudication
_Measured 2026-08-24 on `ana-ml2` against
`/tank/aimodels/gemma4-26b-a4b-it-heretic-bf16` (llmfan46 abliterated trainee)._
Division of labour for this run: **Eitri writes the harness, brokkr-smithy-dev
audits, infra-ops owns the GPU window and executes.** This document is the
sizing infra-ops owes; it is arithmetic against the real checkpoint and the
real card, not an estimate.
---
## 1. ⚠ QLoRA IS NOT AVAILABLE ON THIS ARCHITECTURE
**The proposed shape was QLoRA r64. It cannot be run as specified**, and the
reason is structural rather than a tuning preference.
The checkpoint stores each layer's 128 experts as **two fused 3-D
`nn.Parameter` tensors**, not as 128 `nn.Linear` modules:
model.language_model.layers.N.experts.gate_up_proj BF16 [128, 1408, 2816]
model.language_model.layers.N.experts.down_proj BF16 [128, 2816, 704]
Note the absence of a `.weight` suffix — compare `mlp.down_proj.weight`
(an `nn.Linear`) against `experts.down_proj` (a bare parameter). That is the
tell, and it is decisive: **`bitsandbytes` 4-bit replacement walks `nn.Linear`
modules.** A fused 3-D parameter is not one, so it is skipped and stays BF16.
What `load_in_4bit=True` would actually buy on this model:
| block | params | BF16 | after bnb NF4 | saved |
|---|---:|---:|---:|---:|
| **MoE experts** (fused 3-D — **NOT quantized**) | 22.84 B | 42.54 GiB | **42.54 GiB** | **0** |
| lm attention (`nn.Linear`) | 1.11 B | 2.07 GiB | 0.52 GiB | 1.55 |
| dense shared MLP (`nn.Linear`) | 0.54 B | 1.00 GiB | 0.25 GiB | 0.75 |
| vision tower (`nn.Linear`) | 0.57 B | 1.06 GiB | 0.27 GiB | 0.79 |
| embed (tied, normally kept BF16) | 0.74 B | 1.38 GiB | 1.38 GiB | 0 |
| router + norms | 0.01 B | 0.02 GiB | 0.02 GiB | 0 |
| **total** | **25.81 B** | **48.07 GiB** | **~44.98 GiB** | **~3.1 GiB** |
**88.5% of the model is in tensors bitsandbytes cannot touch.** "QLoRA" here
means paying the NF4 dequant tax on 6% of the weights to save 6% of the
footprint. The premise does not survive contact with the checkpoint.
> **Eitri: do not hard-code a `BitsAndBytesConfig` / `load_in_4bit` path.**
> It will not error loudly — it will load, report a 4-bit model, and quietly
> leave 42.5 GiB in BF16. Same silent-failure shape as the stale chat template.
**The one thing that could overturn this** is a third-party fork shipping
custom grouped-GEMM 4-bit MoE kernels for this specific architecture (Unsloth
is the candidate). **Not chased, deliberately** — see §4, where the run fits in
BF16 without displacing anything the fleet depends on, which collapses QLoRA's
value to zero. If it is ever revisited, it must be *before* the harness
hard-codes a quantization path, not after.
**Verdict: plain LoRA on BF16 weights.**
---
## 2. What the run actually costs
Adapter targeting `q_proj,k_proj,v_proj,o_proj` at r64, computed from the real
tensor shapes:
| | layers | per layer | total |
|---|---:|---:|---:|
| sliding-attention (q 4096, kv 2048, o 4096) | 25 | 1,507,328 | 37,683,200 |
| full-attention (q 8192, kv 1024, o 8192) | 5 | 1,654,784 | 8,273,920 |
| **trainable** | | | **45,957,120** (0.178% of base) |
⚠ **`v_proj` DOES NOT EXIST ON LAYERS 5, 11, 17, 23, 29.** Those are the
`full_attention` layers, and `attention_k_eq_v: true` means one projection
serves both K and V. Consequences the harness must respect:
- PEFT matches by name suffix, so a `v_proj` target **silently produces no
adapter** on those five layers. Do not assert a fixed adapter count.
- Adapting `k_proj` on a global layer **adapts K and V simultaneously** — a
different intervention than on the sliding layers. If that asymmetry matters
to the recipe, say so explicitly rather than discovering it in the loss curve.
### Memory budget, batch 1, `max_seq_len` 8192
| item | GiB | note |
|---|---:|---|
| base weights BF16 | 48.07 | measured: 25,805,936,206 params × 2 B |
| adapters + grads + AdamW fp32 m/v | 0.75 | 45.96 M trainable — rounding error |
| checkpointed layer inputs | 1.29 | 30 × 8192 × 2816 × 2 B |
| recompute peak, one layer | ~2.5 | 8192 tok × top-8 of 128, `moe_intermediate 704` |
| loss head, **fused/chunked CE** | ~2.0 | see the warning below |
| CUDA context + cuBLAS + fragmentation | ~3.0 | the item `--gpu-memory-utilization` never covered |
| **total** | **~57.6** | |
Marginal cost per extra sequence in the micro-batch: **~2.5 GiB.**
| micro-batch | GiB |
|---:|---:|
| 1 | 54.3 |
| 2 | 56.8 |
| **4** | **61.8** |
| 6 | 66.8 |
| 8 | 71.8 |
### ⚠ The loss head is the whole ballgame, and it is not in the brief
`vocab_size` is **262,144** and `final_logit_softcapping` is **30.0**. One
8192-token sequence produces **2.147 billion logits**. Through a naive HF
`ForCausalLM` loss that is:
BF16 logits 4.0 GiB
fp32 upcast 8.0 GiB
softcap tanh saved 8.0 GiB (autograd keeps the pre-cap tensor)
softmax + grad 8.0 GiB
------------------------------
~28-30 GiB transient, at BATCH 1
Naive CE at batch 1 lands the run at **~85.6 GiB on a 95.6 GiB card** — it will
appear to work and then OOM on the first long sample. At micro-batch 4 it is
~120 GiB and never starts. **Fused/chunked linear cross-entropy is mandatory,
not an optimization.**
⚠ Honest uncertainty: Liger ships per-architecture patches and Gemma-4 MoE with
softcapping may not have one. Three ways out, in order of preference —
(a) generic `LigerFusedLinearCrossEntropyLoss` wired against the lm_head with
softcapping applied inside the chunk; (b) `cut-cross-entropy`; (c) hand-rolled
sequence-chunked CE. **This must be proven on a 10-step smoke run before the
window is booked**, because everything else in this document assumes it works.
### Step count
58.2 M tokens / 20,576 samples = **2,829 tokens/sample average** — well under
8192, so packing matters.
- Packed to 8192: **7,104 sequences.** At micro-batch 4 × grad-accum 4
(effective 16) → **444 optimizer steps for the whole epoch.**
- ⚠ That is a *small* step count. A "checkpoint every 100 steps" default gives
four checkpoints across a multi-hour run. This is exactly why the amendment
asked for **wall-clock-interval checkpointing, not step-count** — the case is
now concrete, not hypothetical.
- ⚠ **Packing must use `position_ids` + varlen/block-diagonal attention.** Naive
concatenation bleeds samples into each other. `sliding_window` is 1024 on 25
of 30 layers so the damage is bounded there — but the 5 `full_attention`
layers see the entire packed sequence.
**Open question for brokkr/Eitri:** what fraction of the 20,576 samples exceed
8192 tokens? Below ~2%, 8192 is right. A long tail means truncation is cutting
the ends off RP scenes, which is where the signal lives.
### Runtime
Active parameters per token ≈ **3.67 B** (2.93 B routed + attention, plus the
0.74 B tied lm_head matmul). Forward + backward + gradient-checkpoint recompute
≈ 6 × active × tokens = **1.28e18 FLOPs** for the epoch.
At 10–25% MFU on a 300 W-capped Max-Q card — HF MoE paths with 704-wide experts
are not efficient — **4 to 10 hours, most likely ~6.** Treat as a band, not a
number; it will be measured on the smoke run.
---
## 3. Where it fits (measured 2026-08-24, 18:20 PDT)
Card total: 97,887 MiB = **95.60 GiB** each.
| | GPU0 | GPU1 |
|---|---|---|
| resident before the window | `vllm-gen` 42,508 MiB (up 3 h) | `vllm-mog-sec` 56,624 MiB + `embed` 3,304 + `reward` 9,512 + `coder` 6,158 + `rerank-a3` 2,170; Scriberr pinned here, loads on demand |
| free | 54,741 MiB = **53.46 GiB** | 19,446 MiB = **18.99 GiB** |
Three placements were on the table:
- **GPU0 beside `gen`: does not fit.** 53.46 GiB free against ~57.6 GiB needed —
short by ~4 GiB. And `gen` is only three hours old: measured footprint runs
38.5 GiB fresh → 42.5 GiB at 3 h → 45.6 GiB at 3 days. Budgeting against the
current number is budgeting against a moving one.
- **GPU1 with `mog-sec` stopped: 76,070 MiB free.** Fits, but shares a card with
four small seats and Scriberr.
- **GPU0 with `gen` MOVED OFF: the whole card.** ← what was chosen.
---
## 4. The window, as executed
**Operator call, 2026-08-24: move `gen` to GPU1 and stand `sec` down, so GPU0 is
emptied completely rather than shared.** This is strictly better than training
beside `gen`: the tune gets 95.60 GiB with no co-tenant, and the fleet's general
seat never goes dark beyond its own ~5-minute restart.
before: GPU0 [ gen 42.5 ] GPU1 [ sec 55.3 | small seats 20.7 ]
after: GPU0 [ ---- empty, 95.60 GiB ---- ] GPU1 [ gen ~41 | small seats 20.7 | ~33 free ]
`sec` is genuinely in use and this is not free — but it is the smaller blast
radius by a wide margin:
| | `gen` | `sec` |
|---|---|---|
| aliases | 7 (`gen`, `gen-reasoning`, `chat-judge`, `image-judge`, summarizer/classifier family) | 2 (`sec`, `sec-reasoning`) |
| standing role | the fleet's general seat; a documented always-available dependency in global `CLAUDE.md` | M.O.G.-SEC, niche |
| measured traffic | 765 busy-engine log lines in 24 h — continuously in use | bursty; peak 8 concurrent, **last request ~5 h ago** |
Traffic to `sec` arrives from `10.250.50.70` (the LiteLLM gateway), so the
aliases will fail at the gateway for the duration. Per the standing rule, let
them fail — **do not route `sec` to another model as a stand-in.**
Both directions are playbooks, and **the order in each is load-bearing**:
scripts/elway infra-ops@10.250.50.54 --playbook playbooks/ana-ml2-training-window-open.yaml
scripts/elway infra-ops@10.250.50.54 --playbook playbooks/ana-ml2-training-window-close.yaml
⚠ `gen` runs at `--gpu-memory-utilization 0.43`, which vLLM reads as a fraction
of **total** card memory: 42,091 MiB must be *free at startup* or the engine
refuses to boot. GPU1 has 19,446 MiB free while `mog-sec` is up. **Recreating
`gen` onto GPU1 before stopping `mog-sec` takes the fleet's main seat down and
leaves it down.** The open playbook stops `mog-sec` first and hard-gates on the
freed memory; the close playbook mirrors it, because `mog-sec` needs 50,901 MiB
of its own and cannot start until `gen` has vacated GPU1.
⚠ Invoke elway as `infra-ops@10.250.50.54`, not the `ana-ml2` ssh-target — that
resolves to `lkraven`, which has no NOPASSWD sudo, and elway aborts at its sudo
probe.
### ⚠ MEASURED 2026-08-24 — the estimates below this line were ~3× optimistic
Everything above was arithmetic. This was run on the real checkpoint on GPU0
with synthetic tokens (`/tank/erp-tune/smoke_ce.py`), and it moves the answer:
| config | peak | verdict |
|---|---:|---|
| naive CE, bsz1 seq 8192 | **81.93 GiB** | fits, ~14 GiB spare |
| naive CE, bsz1 seq 16384 | **OOM** | tried to allocate 16.00 GiB |
| chunked CE, bsz1 seq 16384 | **65.66 GiB** | ✅ |
| **chunked CE, bsz2 seq 16384** | **79.71 GiB** | ✅ **the run config** |
| chunked CE, bsz4 seq 16384 | **OOM** | — |
**The marginal cost of an extra 16,384-token sequence is ~14 GiB, not the ~5 GiB
estimated.** The estimate modelled gradient checkpointing as storing only layer
inputs plus a modest recompute peak; the real MoE recompute peak (8,192+ tokens ×
top-8 of 128 experts, plus scatter/gather buffers) is far heavier. **Do not size
an MoE run from dense-model intuition — measure it.**
Two predictions did land exactly, which is why the rest of the model of the thing
is trustworthy: **205 target modules** (q30/k30/v25/o30/gate30/up30/down30) and
**74,342,400 trainable params** at r64.
The headline: **chunked CE at seq 16384 costs 16 GiB LESS than naive CE at seq
8192.** Chunking is not an optimisation, it is what makes brokkr's 16384
recommendation reachable at all.
Base load peak: **49,221 MiB**, confirming the 48.07 GiB weight figure.
### Revised run parameters, now that it is a whole card
**FINAL, measured: `max_seq_len` 16384, `per_device_batch_size` 2,
`gradient_accumulation_steps` 8** → effective batch 16, **~1,280 optimizer
steps**, 79.71 GiB of 95.60 with ~15.9 GiB clear.
`max_seq_len` went 8192 → 16384 on brokkr's truncation finding: at 8192 the cap
drops **6.2% of samples but 22.4% of TOKENS** (61.2M → 47.5M), concentrated
*entirely* in dialogue — 46% of c2-logs, 47.5% of pippa, 95.6% of bluemoon —
which is 60% of the mix and the axis the seat exists for. Prose and fireball
truncate at zero. p50 is 2,084 and p90 4,751, so the cost is the long tail only.
⚠ The 79.71 GiB figure is **worst case** — every sample in the micro-batch at the
full cap. Samples are one-per-sequence padded to the batch max, so with p90 4,751
the typical step sits far below it.
⚠ **Keep gradient checkpointing ON**, and keep `enable_input_require_grads()`
with it. Dropping checkpointing looks like ~17% off wall-clock and instead
forces micro-batch 1. Worse, the second call is the silent one: **without
`enable_input_require_grads()` the frozen base produces no gradient through the
checkpointed blocks, every adapter stays at its initialisation, and the run
completes successfully with an inert adapter.** `prepare_model_for_kbit_training`
used to do it as a side effect of the 4-bit path — so removing 4-bit removes it
too, and nothing warns you.
### Harness changes this required (eitri-smithy `62b556b`)
`9d64257` as audited would not have run here. Four fixes:
1. `runtime.py` hardcoded `BitsAndBytesConfig(load_in_4bit=True)` — now a config
key, defaulting off, per §1.
2. Sequence-chunked CE replacing the model's own loss (the measured table above).
3. `chat_template_path` — `apply_chat_template` resolved the checkpoint's own
stale 365-line template and there was **no override parameter anywhere**, so
the upstream-template requirement was not expressible in the code.
4. Gradient checkpointing + `enable_input_require_grads()`.
Plus `training_eligibility_override` / `overridden_blockers` /
`substitute_controls` in the provenance manifest, and `device_map` pinned to
device 0 so the run cannot stray onto the card holding the inference seats.
Also fold in:
- **Scriberr STAYS on GPU1.** (An earlier draft of this document suggested moving
it to GPU0; that was written when training was going to live on GPU1, and it is
now exactly backwards. GPU0 is the training card and wants no co-tenant.)
- **Package as a `uv` venv on `/tank`, not a Docker image.** Root is at **91%
(36 GB free)** and `/var/lib/docker` lives on it; a PyTorch training image
would come close to filling it. `/tank` has 4.0 TB.
- **The run is still resumable-by-design** (INV-T7 + wall-clock checkpointing).
Nothing about a dedicated card removes that requirement — a 4–10 hour window
is long enough that an unresumable run is a bad bet regardless of who owns the
GPU.
---
## 5. Standing warnings that apply to this run
- **Never render training examples through the base's own
`chat_template.jinja`.** Every third-party Gemma-4 derivative ships a stale
one; the trainee's is 365 lines against upstream's 390. Use
`/tank/aimodels/gemma4-26b-a4b-it-bf16/chat_template.jinja`. Training through
the wrong template is train/serve skew with no error — it presents as a
tuning failure.
- **Base path and chat-template path are config keys, not constants.** The
trainee base already moved once (stock BF16 → `-heretic-bf16`).
- **`--gpu-memory-utilization` sizes the KV cache only.** It does not cover CUDA
context, graphs, or non-torch overhead — the same misreading that OOM'd the
char-rp seat.
- **Serving the result is not settled.** LoRA-on-NVFP4 hot-swap was a silent
no-op on vLLM 0.24.0 (#47639, proven quant-agnostic). Retest on the tagged
`vllm/vllm-openai:v0.27.1` already on disk. **If it still no-ops, the harness
must emit merged weights** — and Eitri needs that requirement while he is
early, not after the run.

## 6. Round-1 aborted; throughput root-caused (measured 2026-08-24 22:00 PDT)
Run-01 launched, reached step 19 of 1,312 at ~35–46 s/it, and was **killed by
operator instruction** — not a crash, not an OOM. ETA was ~13.9 h at 8.6% MFU
and the operator elected to root-cause before spending the window.
Nothing was destroyed: the 609 MB encode cache, `order-manifest.jsonl`,
`truncation-report.json` and `resume-run-01.sh` are all preserved at
`/tank/erp-tune/run-01/`. **There are no checkpoints** — the first was due at
step 100, so brokkr's `lora_B` inert-adapter gate never ran. That question is
open and moves to the restart.
Model-agnostic lessons from this investigation are in
[`training-throughput-playbook.md`](training-throughput-playbook.md); the
probes are at [`scripts/training-probes/`](../../scripts/training-probes/).
What follows is Gemma-4-specific.
### 6.1 Where the step time goes
Real checkpoint, GPU0, `attn_implementation="sdpa"`, PEFT + gradient
checkpointing + the chunked CE, fwd+bwd, best-of-2 after warmup:
| shape | time | peak |
|---|---:|---:|
| 2 × 2,048 | 1.776 s | 53.2 GiB |
| 2 × 8,192 | 11.570 s | 62.3 GiB |
| 2 × 16,384 | **35.017 s** | 76.6 GiB |
Fitting `t(w) = A·w + B·w²` over all three (per-sequence `w`, batch 2):
A = 6.8715e-04 s/token B = 8.8509e-08 s/token²
| w | predicted | measured | linear | quadratic | quad share |
|---:|---:|---:|---:|---:|---:|
| 2,048 | 1.779 | 1.776 | 1.407 | 0.371 | 20.9% |
| 8,192 | 11.569 | 11.570 | 5.629 | 5.940 | 51.3% |
| 16,384 | 35.017 | 35.017 | 11.258 | 23.759 | **67.8%** |
**Two terms, three points, residuals under 3 ms across an 8× range.** No fixed
per-batch term was needed, which refutes the launch-bound hypothesis outright —
~3,840 expert-GEMM launches per forward are not the cost.
Independently, the profiler kernel table (device rows only — see playbook §3.4):
| device kernel | ms | of step |
|---|---:|---:|
| `fmha_cutlassB_bf16_aligned_128x64_k65536_sm80` (attn BWD) | 16,144.6 | 46.1% |
| `fmha_cutlassF_bf16_aligned_32x128_gmem_sm80` (attn FWD) | 6,691.2 | 19.1% |
| `cutlass_80_tensorop_bf16_s16816gemm` ×3 (dense GEMM) | 2,774.0 | 7.9% |
| elementwise / vectorized / unrolled ×9 | 4,787.4 | 13.7% |
| gather / Memcpy DtoD / dropout | 951.6 | 2.7% |
| **attention total** | **22,835.8** | **65.2%** |
**Scaling fit says 67.8% quadratic; kernel table says 65.2% attention. Two
independent methods, 2.6 points apart.**
### 6.2 ⚠ The attention kernels are Ampere, on a Blackwell card
`fmha_cutlass*_sm80` on sm_120. There is no Blackwell-tuned attention kernel in
this path at all, and the forward is additionally on `gmem` — the
global-memory fallback tier of the memory-efficient backend, selected when the
working set will not fit in shared memory.
This is the mechanism behind the 100%-SM / 27-TFLOPS / 304-TFLOPS-capable
reading: the chip is saturated running a kernel generation behind on the
dominant cost centre.
The candidate fix is a purpose-built kernel for this architecture's mixed
256/512 head-dim split — `zzhhjjj/gemma-triton-flash-attn`
(`register_triton_attention()`, then `_attn_implementation = "triton_gqa"`),
reported 9.23× over SDPA at N=16K D=256 SWA and 2.94× fwd+bwd at D=512.
`flex_attention` + `BlockMask` is the no-new-dependency alternative.
⚠ **Prefer a UNIFORM backend over a per-layer split.** vLLM special-cased this
exact mixed-head-dim architecture and measured mixed backends **8% slower** than
uniform. And `attn_implementation` is all-or-nothing at `from_pretrained` /
`set_attn_implementation` — per-layer routing requires a custom function
registered on `ALL_ATTENTION_FUNCTIONS` branching on `module.head_dim` /
`sliding_window`.
⚠ **FA2 is not available for this model**: it caps head_dim at 256 and the 5
global layers are at 512. FA3 is Hopper-only. Do not bet on FA4 on sm_120.
### 6.3 Masking is CORRECT — and padding is what costs
Band structure asserted directly against the real config at n=16,384:
sliding_attention max 1,024 allowed/row, saturates at row 1,023 PASS
Constraints were **not** silently dropped; the 25 sliding layers were genuinely
windowed. Run-01 was training the model we intended.
The same probe found the mechanism nobody had measured:
| 2D mask supplied | `full_attention` mask returned |
|---|---|
| `None` | **`None`** → `is_causal` fast path AVAILABLE |
| all-ones (no padding) | **`None`** → `is_causal` fast path AVAILABLE |
| right-padded (what `collate_mixed` emits) | 4D `16384²` → **fast path LOST** |
**Padding is what pins the 5 global layers to an explicit mask.** The 25
sliding layers get a 4D tensor either way — `sdpa_attention_forward` sets
`is_causal=True` only when `attention_mask is None`, and a 1024 window cannot
be expressed as `is_causal`.
Isolated, same width, only the mask differing:
2 × 16,384, no padding 35.244 s 26,048 loss targets
2 × 16,384, 50% pad on row 1 38.567 s 19,640 loss targets
**9.4% slower for 24% less work.**
### 6.4 The corpus is 29.9% padding — and bucketing is the biggest win available
Measured off the preserved encode cache in true `SequentialSampler` order:
records 20,982 (3,583 rp-dialogue / 12,003 prose-chunk / 5,396 actual-play)
seq len min/mean/max 142 / 2,752 / 16,384
micro-batches (mb=2) 10,491
real tokens 57,733,156
padded tokens 82,337,318
PADDING WASTE 29.9%
mb width p50/p90/p99 2,092 / 10,634 / 16,341
micro-batches at 16,384 3 of 10,491 (0.0%)
⚠ Note the last line against §6.1: **the 2 × 16,384 benchmark shape occurs in
three micro-batches out of 10,491.** Weighted over the real distribution the
quadratic share is ~51%, not 67.8%.
**Bucket-to-pair, shuffle-to-mix** (brokkr's design, validated on measured
lengths — form micro-batches within length buckets, then shuffle the resulting
*micro-batches* globally):
| bucket | waste | predicted step | zero-pad mb | roots/accum window |
|---:|---:|---:|---:|---:|
| current | 29.9% | 44.3 s → 16.13 h | 0.1% | 3.68 |
| **2** | **0.0%** | **28.6 s → 10.40 h** | **78.3%** | 3.56 |
| 8 | 0.0% | 28.6 s → 10.41 h | 65.3% | 3.54 |
| 32 | 0.1% | 28.6 s → 10.43 h | 41.9% | 3.55 |
| 128 | 0.6% | 28.8 s → 10.51 h | 14.7% | 3.55 |
| 512 | 2.4% | 29.7 s → 10.82 h | 4.1% | 3.61 |
**≥35.5% wall clock, no kernel work, no new dependency, peak memory unchanged.**
Two findings that changed the design:
- **Bucket size is not a diversity knob.** Roots per accumulation window are
flat at 3.54–3.61 across a 256× range. The global micro-batch shuffle does
all the mixing. Use the tightest bucket.
- **35.5% is a floor.** Zero-pad micro-batches go 0.1% → 78.3%, which puts the
5 global layers back on `is_causal` for most of the run (§6.3). The cost
model does not capture that. Direction certain, magnitude not yet measured at
representative shapes.
⚠ **Source-homogeneity is a real hazard here** — length correlates hard with
root (kvasir short, chunked RP windows long), so length-homogeneous batches are
root-homogeneous batches. The global micro-batch shuffle is what prevents an
accumulation window drawing its whole gradient from one source. It is
load-bearing, not decoration.
### 6.5 The chunked CE is fine — do not swap it
2 × 16,384 CE forward 374 ms of 35.329 s = 1.1%
2 × 4,096 CE forward 93 ms of 4.387 s = 2.1%
⚠ **Forward only** — the `torch.utils.checkpoint` recompute runs inside
`.backward()`, outside the timing window. Even at 3× it is ~3%.
`liger-kernel` fused linear CE is a ~1–3% lever on this shape. §2's finding
stands unchanged: chunking is what makes seq 16384 *reachable*, and it is not
what makes it slow.
### 6.6 MoE is ~8% — stop optimising it
Dense GEMM is 7.9% of the step, confirming the earlier decomposition bound of
~10% from the kernel side.
On `grouped_mm`: **the trace does not adjudicate it.** Run-01 was relaunched on
`eager`, so the profile shows the *default* path — 25,463 `aten::mm` dispatches
in one fwd+bwd, far more than the ~90 a grouped path would produce, so the
default is per-expert sequential. Whether the flag changes that when set is a
different measurement and was not run. At 7.9% it is not worth running.
### 6.7 Restart parameters for round 2
**Do not relaunch without the sampler change.** It is the only lever that wins
under every branch of the diagnosis.
1. **Implement bucket-to-pair + shuffle-to-mix** in the harness, tightest
bucket, global micro-batch shuffle. Expected ~16.1 h → ~10.4 h or better.
2. **Re-assert the mask band structure** after the sampler change —
`scripts/training-probes/step0_mask.py`, 30 s, no GPU. The sampler touches
batch composition, which is what drives mask construction.
3. **Resume with `/tank/erp-tune/resume-run-01.sh`, NEVER the original launch
command** — it begins `rm -rf /tank/erp-tune/run-01` and would destroy the
609 MB encode cache (2.5 min to reuse, ~4.3 h to rebuild). ⚠ A sampler change
alters record *order*, not encoding, so the cache stays valid — but bump
`encode_version` if anything upstream of `input_ids` changes.
4. **Run the `lora_B` inert-adapter gate at step 100.** It never ran in round 1.
Norm every `lora_B` tensor in the checkpoint: all-non-zero = real, all-zero =
INERT (kill the run), partial = module-selection problem. This is the one
failure that stays invisible until brokkr's acceptance gate reports
base-identical numbers.
5. **The corpus override is ONE RUN ONLY** (`operator-2026-08-25-rnd-run`). A
second run needs a second operator grant.
6. **Attention backend is round 2's second lever**, gated on an A/B on the
replica — not on argument. It can run while the tuned job trains.
⚠ GPU0 is currently **reserved and idle** by operator instruction; `sec` /
mog-sec remains down. The window is still open, so
`playbooks/ana-ml2-training-window-close.yaml` has NOT been run.

# Gen-seat candidate evaluation — 2026-08-21
Cold-Fusion was abandoned (see `persistent-memory.md`); the seat is on
`qwen38-27b-heresy-nvfp4-mixed`. Two replacement candidates were put up. All facts
below come from the HF registry and from reading the artifacts directly — the
safetensors headers were fetched with HTTP **Range** requests, so the tensor census
cost about a megabyte rather than a 20 GB download.
## The candidates
| | `orcarouter/Qwen3.8-27B-Uncensored` | `preetpatel/…-NVFP4` |
|---|---|---|
| what | BF16 source weights | NVFP4 quant **of orcarouter** |
| size | 55.6 GB | 19.7 GB |
| base | `Qwen/Qwen3.8-27B` (**stock Qwen**) | orcarouter |
| **MTP tensors** | **15 ✓** | **0 ✗** |
| visual tensors | 333 ✓ | 333 ✓ |
| scheme | n/a (bf16) | **NVFP4 W4A4** ✗ |
| `re:^mtp.*` in ignore | n/a | **absent** ✗ |
| traction | 3,278 dl / 60 likes | 36 dl / 0 likes |
| gated | yes — **our token already has access** | no |
| chat template | **sha `c3cf9e34` — byte-identical to the live heresy seat** | same |
## Verdict: preetpatel is disqualified, on two independent hard failures
**1. Zero MTP tensors.** Read straight from the safetensors header: 2,672 tensors,
**none** matching `mtp.*`. The author's own `recipe.yaml` asks to ignore
`re:.*mtp.*`, but the written `config.json` contains no mtp ignore entry at all —
while `re:.*visual.*` expanded to 110 explicit entries. That asymmetry is the
signature of llm-compressor pruning an ignore pattern that matched nothing, i.e.
the MTP head was never loaded and never quantized. It is the same
`re:^mtp.*`-pruning trap documented in the playbook, seen from the outside.
Cost: no speculative decoding. Our seat runs MTP at ~59% acceptance and 118 tok/s;
without it, roughly half the decode throughput.
**2. NVFP4 W4A4 — 4-bit activations.** `input_activations: num_bits 4, type float`.
This is precisely the AEON failure mode we spent a multi-day saga diagnosing and
purging: the activation-fidelity gradient is W4A4 < W4+FP8 < W4+bf16, W4A4 was
responsible for ~15-20% stochastic degeneration, and W4A4 collapses past ~30k
context. **The gen seat serves 262K.**
Either failure alone would rule it out. It is also one day old with 36 downloads.
## orcarouter checks out as a quant source
Stock-Qwen base (not a reasoning-compression finetune — the trait that sank
Cold-Fusion), Arditi-et-al. single-direction abliteration, MTP and vision both
explicitly preserved and verified at 15/333, chat template byte-identical to the
build we are serving right now, and the gate is already accepted on our token.
## Third option, noted and not recommended
`orcarouter/Qwen3.8-27B-Uncensored-FP8` — 76,109 downloads, 693 likes, far more
traction than either candidate. **But 30.9 GB against NVFP4's 22 GB**, and GPU0 is
zero-sum with meromero co-resident: +9 GB of weights comes straight out of the KV
pool, taking it from ~14.4 GiB / 403k tokens to roughly 5 GiB / ~150k — which
breaks 262K context at 1.5x concurrency. Viable only if the seat gives up long
context or meromero moves.
## The imatrix constraint — read before committing to it
The operator asked for imatrix if we quant ourselves. **This is not a switch.**
`quant_mixed_nvfp4.py` already sets `observer="imatrix_mse"` on the W4A4 group and
has **never once used it** — llm-compressor logs `no importance data available.
Falling back to uniform MSE` and proceeds. Playbook §3.13 documents this and warns
explicitly: *do not "fix" it by assuming an imatrix would help; verify first that
your llm-compressor version can consume an externally supplied importance matrix at
all, and in what format.* Parked as `park/…imatrix-mse…` (id 42) with the
calibration corpus that would feed it.
Also note the W4A16 portions of the mixed recipe are **data-free by construction** —
llm-compressor infers `DataFreePipeline` for weight-only quantization and ignores
calibration data entirely. Imatrix can only ever bite on the W4A4 MLP group.
So "quant with imatrix" is two projects: an unscoped capability investigation, and
then the ~2h quant. Recommendation is to decouple them — ship the proven recipe
first, run imatrix as its own bounded experiment. Every A/B we hold is
uniform-MSE-to-uniform-MSE, so a non-imatrix build stays directly comparable to
heresy's PPL 6.910 / 47.2% acceptance.
## Mandatory step if we pull
Run `services/gen-seat-mixed-quant/bench/think-leak/think_prior.py` on the bf16
**before any GPU time**. It is a ~10s CPU measurement and it is the gate that would
have disqualified Cold-Fusion before its 300-trial study ever ran. Prior is
favourable — stock-Qwen base, template identical to heresy, which measures <0.002
against Cold-Fusion's 0.185 — but measure, don't assume.

# Addendum — M.O.G.-SEC pen-test model (same night)
Two `Blackfrost-Research/M.O.G.-SEC-27B-1M-CTX` candidates for the pen-test
project: a BF16 and a pre-made NVFP4. **Same verdict as gen-seat: pull the BF16,
quant ourselves.** Read directly off the artifacts via HTTP Range.
| | BF16 | pre-made NVFP4 |
|---|---|---|
| MTP tensors | 15 ✓ | **0 ✗** |
| scheme | n/a | **ModelOpt W4A4** ✗ |
| context | native 262K (config), 1M claimed | same |
The pre-made NVFP4 is disqualified on **three** grounds, one unique to this model:
ModelOpt **W4A4** (4-bit activations — the AEON degradation mode), **zero MTP**,
and — the sharp one — **W4A4 on a 1M-context model is self-defeating**, since
W4A4 fidelity collapses past ~30k. A long-context model quanted on the activation
scheme that fails hardest at long context works against itself.
The BF16 quanted cleanly (`mog-sec-27b-nvfp4-mixed`, 23.4 GB) and is **served** in
the retired fable slot (ana-ml2 GPU1 :8019, aliases `mog-sec` / `mog-sec-reasoning`).
Gates: format screen 1.11e-05, surface 6/6, MTP 55.3%, vision 7/3/1, and a
capability smoke 4/4 (it delivers offensive-security content, does not refuse).
**The 1M is not real on our path.** `rope_scaling: None` in the weights' config
(native Qwen3.8 is 262K), and the repo's 1M is an SGLang/DFlash2 deployment kit.
We serve native 262K. A true 1M seat would be a separate SGLang project — flagged,
not attempted.

# ESH IPv6 naming scheme
Every ESH LAN carries an **eight-hex-digit phrase** as the first half of the
interface identifier. Picked 2026-08-18/19. This file is the canonical record.
> **Why this file exists.** The scheme originally lived as a single line in
> `persistent-memory.md` and was silently deleted by a `memory: snapshot`
> commit (`837fa36`). Recovering it took a hunt through session transcripts to
> find the commit that had held it. A naming convention is not temporal state —
> it belongs in a document, so it now is one.
## The names
| network | hex | reads as |
|---|---|---|
| `Default` | **`4BA5:3417`** | A BASE FOR IT |
| `esh-mgmt` | **`15DA:B055`** | IS DA BOSS |
| `esh-server` | **`4411:B105`** | FOR ALL BIOS |
| `esh-userland` | **`CAFE:4411`** | CAFE FOR ALL |
| `esh-iot` | **`4DBA:D107`** | FOR DA BAD IOT |
| `esh-cameras` | **`1533:FACE5`** | I SEE FACES |
| *(reserved)* DMZ | **`4411:DBAD`** | FOR ALL DA BAD |
The DMZ name is **claimed against a network that does not exist yet** — there is
no DMZ on the ESH UDM. Do not reuse it.
Substitutions are the standard hexspeak set: `0`→O, `1`→I/L, `5`→S, plus letters
that are already native hex (`A`–`F`). Anything outside `0-9a-f` is not
expressible — `b0ss` and `c00l` do **not** work, which is why the set above uses
`B055` and avoids `c00l` entirely.
House style, arrived at rather than designed: **eight digits, and a complete
phrase rather than a single word.** Words are allowed to straddle the group
boundary (`4DBA:D107` is `4·D·BAD·107`); the phrase reads through the colon.
## Address structure
```
2607:73c0:402:1d02 : 4411:b105 : 50 : 45
└──── ISP /64 ────┘ └ segment ─┘ └ 10.0.50.45 ┘
```
- **Prefix** — Cityside's, not ours to name. ESH holds a `/56`
(`2607:73c0:402:1d00::/56`, 256 × /64); the subnet id is assigned by UniFi's
`ipv6_pd_prefixid`. `esh-cameras` is `1d00`, `esh-server` is `1d02`.
- **Segment word pair** — 32 bits, from the table above.
- **Host** — the last two IPv4 octets, written as literal digits so they read
straight off the address. `10.0.50.45` → `:50:45`.
The scheme lives entirely in the **interface identifier**, so it is
**delegation-size independent**. It works identically on a `/56`, a `/48`, or
NH3's single `/64`. It never competes with the subnet id, which is far too small
to hold a word (8 bits at ESH — two hex digits).
Note: `4411:b105:50:45` fills all four host groups, so there is **no `::`** in
these addresses. Writing `...::4411:b105:50:45` is malformed and will be
rejected.
## What can and cannot carry a name
| slot | nameable? |
|---|---|
| `/64` subnet id (`ipv6_pd_prefixid`) | **No** — 8 bits at ESH, two hex digits, no room for a word |
| the gateway's own address | **No** — fixed at `::1` by UniFi, no field for it |
| a UniFi *client* reservation | **No** — UniFi has no IPv6 equivalent of `use_fixedip` |
| **a host taking its own address** | **Yes** — this is the one that works |
⚠ **The original note concluded these names could never appear in a `dig` or
`ip -6` output. That is wrong.** The first three rows are correct, but they only
establish that *UniFi* cannot assign the address. A Linux host can simply take
one within its own advertised prefix, and the router gets no vote. Appliances
with no shell — cameras, most IoT — genuinely cannot, so `1533:FACE5` and
`4DBA:D107` are likely to stay documentation-only.
## Applying it to a host
Do **not** use an `iface … inet6 static` stanza: on Debian that sets
`accept_ra=0`, killing SLAAC and the IPv6 default route — a good way to strand a
headless box. Use an `if-up.d` hook that derives the live prefix instead.
Live example, `/etc/network/if-up.d/ipv6-scheme-addr` on `esh-docker-vm`:
```sh
#!/bin/sh
[ "$IFACE" = ens18 ] || exit 0
(
i=0
while [ $i -lt 30 ]; do
PFX=$(ip -6 -o addr show dev "$IFACE" scope global 2>/dev/null \
| awk '{print $4}' | cut -d/ -f1 | head -1 | cut -d: -f1-4)
if [ -n "$PFX" ]; then
ip -6 addr replace "${PFX}:4411:b105:50:45/64" dev "$IFACE" && exit 0
fi
sleep 2
i=$((i + 1))
done
) >/dev/null 2>&1 &
exit 0
```
Three deliberate properties:
- **The prefix is derived, never hardcoded** — self-heals if Cityside
re-delegates.
- **Backgrounded with a retry** — SLAAC may not have landed when `if-up.d` runs,
and a hook that blocks or fails would stall interface bring-up.
- **Additive** — `/etc/network/interfaces` already sources `interfaces.d/`;
nothing existing is edited, and removal is one `rm`.
Remaining gap: a *mid-life* prefix change is only picked up at the next
interface-up. A timer would close it; not worth building until the prefix is
observed to actually move.
## Deployed
All three Linux hosts on `esh-server` now carry the segment name, with the last
two groups reading straight off their IPv4 address:
| host | address | v4 | applied via |
|---|---|---|---|
| `esh-docker-vm` (AdGuard) | `2607:73c0:402:1d02:4411:b105:50:45` | 10.0.50.45 | `if-up.d` on `ens18` |
| `esh-pve-nas` | `2607:73c0:402:1d02:4411:b105:50:55` | 10.0.50.55 | `if-up.d` on `vmbr0` |
| `esh-vm-db` | `2607:73c0:402:1d02:4411:b105:50:60` | 10.0.50.60 | `if-up.d` on `ens18` |
`esh-docker-vm`'s is load-bearing, not decorative: the ESH UDM advertises an
IPv6 resolver to clients via RDNSS, macOS prefers it over the DHCPv4-supplied
one, so whatever sits there is what resolves `*.internal` for every Mac on the
network. It previously pointed at AdGuard's **MAC-derived SLAAC address**, which
would have broken if that VM's NIC ever changed. Both `esh-userland` and
`esh-server` now advertise the scheme address instead
(`dhcpdv6_dns_auto=false` + `dhcpdv6_dns_1=<address>`), verified on the wire by
soliciting an RA and parsing option type 25.
### ⚠ Proxmox bridges need `accept_ra=2` or SLAAC never runs
`esh-pve-nas` had **link-local only** despite `accept_ra=1`, `autoconf=1` and
IPv6 enabled — every sysctl looked correct. The cause: **`vmbr0.forwarding = 1`**
(Proxmox sets per-interface forwarding on bridges), and the kernel ignores RAs on
a forwarding interface unless `accept_ra` is explicitly **`2`**. `accept_ra=1`
means "accept only if not forwarding", so it silently did nothing.
Fixed in `/etc/sysctl.d/60-ipv6-accept-ra.conf` on that host:
```
net.ipv6.conf.vmbr0.accept_ra = 2
net.ipv6.conf.vmbr0.accept_ra_defrtr = 0
```
`accept_ra_defrtr=0` is deliberate — it takes the advertised **prefix** (so
SLAAC configures an address) while **declining the default route**, so a
hypervisor gains an IPv6 identity with no change to its routing behaviour.
Verified after: SLAAC address present, v6 default routes still **0**, v4 intact.
Expect the same on any other Proxmox node when its LAN gets IPv6.
### Getting into a host with no direct root
`esh-vm-db` refuses key auth for `root` and `infra-ops`, and `lkraven`'s sudo
wants a password. It is VMID 101 on `esh-pve`, and the **QEMU guest agent** runs
as uid 0 inside it, so the hook was installed with:
```
qm guest exec 101 -- /bin/sh -c 'echo <base64> | base64 -d > /etc/network/if-up.d/... '
```
base64 because quoting a multi-line script through two SSH layers mangles it.
Worth remembering as the general path for guests whose credentials are not
vaulted.
Every Linux host on `esh-server` now carries its name. The remaining ESH
segments have no eligible hosts: `esh-cameras` and `esh-iot` are appliances
with no shell, and `esh-mgmt`, `esh-userland` and `Default` are still
`ipv6_interface_type: none` pending the firewall-policy pass — enabling SLAAC
there gives every client a globally reachable address.

# Model quantization playbook — the lessons that keep costing us hours
**Read this before starting any new quant.** Not the per-model runbooks — those are worked
examples of a *specific* model at a *specific* point in time, and several carry claims that are
now false (see §7). This file owns the **transferable** part: what recurs regardless of which
model dropped this week.
Written 2026-08-15, after the fourth quant in five weeks re-discovered the third-known instance
of the same loader-class bug. Scope: NVFP4 / FP8 / mixed-precision on the Blackwell boxes
(ana-ml2), vLLM-served. Ampere (irv-ml1) has no native FP4/FP8 — see §6.
**Maintenance rule.** When a quant teaches you something *model-agnostic*, it lands here and the
per-model README links up. When it's model-specific (this checkpoint's odd tensor names, this
finetune's missing config), it stays in the per-model artifact. If you find yourself writing a
"Gotchas" section that repeats §3, you are re-litigating — add the delta here instead.
---
## 1. The 60-second decision: which scheme
On Blackwell + vLLM, for a dense-or-hybrid VL model you intend to serve at long context:
| want | scheme | notes |
|---|---|---|
| **default, best speed/accuracy** | **mixed: NVFP4 W4A4 bulk MLPs + FP8 W8A8 attention/`lm_head`/last-8-layer MLPs** | the current answer. §2. |
| max fidelity, don't care about prefill | NVFP4 **W4A16** (weight-only) | forces the **Marlin** kernel — ~half the prefill of native FP4 |
| small model, VRAM is free | FP8 **W8A8** | safe and simple; 2× the weight bytes of 4-bit |
| — | ~~"W4A8" = NVFP4 weights + FP8 activations~~ | **DOES NOT EXIST.** §3.1 |
**Measured on Qwen3.8-27B (2026-08-15), W4A16 → mixed:** decode +18%, prefill **+78–98%**,
MTP acceptance unchanged, perplexity +1.7%, weights −19%.
Note the shape of that: **decode barely moves, prefill nearly doubles.** Decode at batch-1 is
memory-bandwidth-bound and the weights are 4-bit under either scheme, so there is little to win;
prefill is compute-bound, which is where native FP4 tensor cores replace the Marlin
dequantize-to-BF16 path. If someone promises you a big *decode* win from a scheme change, be
skeptical — and go measure §5 before believing it.
**The accuracy cost is real and is paid on purpose.** Operator ruling 2026-08-15: the ~1.7%
perplexity is an acceptable price for the speed. Settled — don't re-litigate. For correct
attribution: it is the **activation**-quantization cost (A4/A8 vs BF16 activations), *not* an MTP
cost. Turning MTP off does not recover it; only reverting the quant does.
---
## 2. The reference recipe (mixed-precision)
Lifted from `unsloth/Qwen3.8-27B-NVFP4` and replicated in-house. **Prefer replicating a published
recipe from a reputable quantizer over inventing one** — they have already paid for the
sensitivity analysis.
| group | scheme | targets |
|---|---|---|
| `group_0` | FP8 W8A8 — channel weights (static) + per-token dynamic activations | `self_attn.{q,k,v,o}_proj`, `linear_attn.{in_proj_qkv,in_proj_z,out_proj}`, `lm_head`, **the last 8 layers' MLPs** |
| `group_1` | NVFP4 W4A4 — `tensor_group` gsize 16, fp8 scales, `imatrix_mse` weights, `dynamic:"local"` activations | **all remaining** MLP `{gate,up,down}_proj` |
| kv cache | FP8 static tensor | |
| ignore | vision tower, `linear_attn.{norm,in_proj_a,in_proj_b}`, `re:^mtp.*` | |
Three things in there are load-bearing and easy to drop:
- **Late layers stay FP8.** Holding the last ~8 layers' MLPs (and `lm_head`) at 8-bit is the
accuracy-preservation trick — late layers are the sensitive ones. Uniform W4A4 is what collapses.
- **`imatrix_mse` on the W4A4 weights**, not `memoryless_minmax`. Importance-weighted; needs
calibration data.
- **Group targets must be non-overlapping.** Do not let `group_1`'s `.*mlp\..*` also match the
late layers and rely on group precedence to sort it out. Enumerate the early layers explicitly
(`re:.*layers\.([0-9]|[1-4][0-9]|5[0-5])\.mlp\.…`) and **prove it** with a dry run (§4.1).
**Toolchain:** `pip install llmcompressor` into stock `vllm/vllm-openai:latest` gives
llmcompressor 0.13 + compressed-tensors 0.18 without disturbing torch/transformers.
**Avoid nvidia-modelopt** — see §3.4.
---
## 3. The recurring landmines
Ordered by how much time each has cost. Every one of these has bitten more than once.
### 3.1 "W4A8" is not a servable shape
vLLM's compressed-tensors dispatcher (`compressed_tensors.py:704-713`) accepts NVFP4 weights with
**exactly two** activation settings:
| `input_activations` | result |
|---|---|
| `None` | W4A16 — and it **forces the Marlin kernel** (`kernels/linear/__init__.py:881-883`) |
| NVFP4 | W4A4, native |
Anything else — **FP8 included** — raises at load:
```
ValueError: For NVFP4 weights, input quantization must also be NVFP4 format, None for NVFP4A16
```
`CompressedTensorsW4A8Fp8` exists but is **INT4** weights (`W4A8_SUPPORTED_TYPES_MAP = {4: int4}`)
gated on `_check_scheme_supported(90, match_exact=True)` — Hopper-exact, so on Blackwell (sm_120)
it is closed twice over. **FP8 enters per-layer-group, never as activations on NVFP4 weights.**
*Cost: one queued task written against an impossible scheme.*
### 3.2 Wrong loader class → silent weight-load failure
**Rediscovered three times.** Load the model through the class vLLM actually serves — the
`…ForConditionalGeneration` / `…ForImageTextToText` **wrapper**, never `AutoModelForCausalLM`.
`AutoModelForCausalLM` resolves a VL config to the text-only inner class and saves a **flat**
config with `model.layers.*` keys. vLLM's weight mapper wants `model.language_model.*` (+
`model.visual.*`). The mismatch does not error — **every layer silently fails to load** and you
get `!!!!` gibberish, or an engine that rejects the checkpoint outright.
*Bit: heretic2 (gibberish), Dark-Scarlett (both vLLM and SGLang refused the checkpoint), and the
2026-08 rounds.*
### 3.3 The MTP head — three separate ways to lose it
Speculative decoding is a large fraction of the seat's throughput. It fails **silently**: the
model serves fine, just at 0% acceptance.
1. **The wrapper class does not instantiate `mtp.*`,** so the quant drops it. Post-quant you must
graft the BF16 `model-mtp.safetensors` back and register its tensors in the output index.
2. **`re:^mtp.*` must be in `quantization_config.ignore`** — else vLLM loads the grafted BF16 head
as though quantized, it comes up **uninitialised**, and acceptance is 0%.
3. **⭐ llm-compressor PRUNES `ignore` entries that matched no module at quant time.** Since the
wrapper never loaded `mtp.*`, the entry matches nothing and is **silently deleted from the
saved config — even though you put it in the recipe.** So it must be re-injected *after* the
graft, and then **verified, not assumed.**
*Cost: three rounds. The verify step caught it live on the third.*
There is also a **modelopt-format-specific** version of this: vLLM 0.24 does not propagate
modelopt `exclude_modules` to the spec-decode *draft* model, which no checkpoint config can fix
(needs a `sitecustomize` runtime patch). Using compressed-tensors avoids it entirely — §3.4.
### 3.8 ⭐⭐ Multi-turn degeneration from TWO real compounding causes — how they masked each other
The most expensive diagnosis this project has had, because there were **two real
causes at once** and each partial fix moved the needle enough to look like *the*
answer. Recorded precisely because the first write-up of this section
over-attributed it to the quant alone; that was wrong.
**Cause 1 (real, upstream): the vLLM `qwen3_5_mtp` × Gated-DeltaNet bug.**
Confirmed by two cross-frontier peers and the tracker (vllm#47087 symptom-twin,
#43559 fix lineage, #51113 fix): the GDN recurrent state cannot roll back on a
partial draft-accept, so speculative decoding corrupts it, worse with context.
Architectural — vLLM/SGLang/llama.cpp mainline all shared it. **Genuinely fixed
enough** by moving to vLLM **nightly** (`v0.27.2rc1.dev150+`, carries #51113):
the operator reported it "significantly better" — this was a real bug, not just
an amplifier.
**Cause 2 (real, quant): full W4A4 is mildly subpar, per the known gradient.**
`sakamakismile/Qwen3.8-27B-AEON-ULTIMATE-UNCENSORED-NVFP4` is **full** W4A4 — 4-bit
*activations* on attention too, the bottom of the activation-precision ordering
already in §1: **W4A4 (A4) < W4+FP8 (A8) < W4+bf16 (A16)**. Not "defective," just
lowest-fidelity; on top of Cause 1 it degenerated ~15-20% of real multi-turn
generations. The FP8-attention **mixed** build (`qwen38-27b-uncensored-nvfp4-mixed`,
same base, same MTP, same nightly) sits a rung up that gradient and is coherent.
AEON was purged 2026-08-17 (operator ruled it no-good; re-pullable from HF).
**Why it cost days — and the process lessons that stand:**
1. **Two real causes compound and mask each other.** Each mitigation (MTP-off,
APC-off, the nightly #51113 fix) partially helped, so each looked like the fix
and then failed in real use. When a mitigation "helps but doesn't fix," suspect
a *second* cause rather than a wrong one.
2. **Stochastic degeneration (~15-20%) is nearly invisible to a small synthetic
probe** — a 7-turn run passes ~4 in 5. n=1 "clean" proves nothing; this class
needs many runs or the operator's real high-volume use. Three non-fixes were
"validated" by a single clean probe here.
3. **Isolate the WEIGHTS in parallel with the serving flags, not after.** Swapping
to a different quant of the same base (AEON→mixed) is what finally separated
Cause 2 from Cause 1; doing it earlier would have shortened the hunt. But note
it would NOT have found Cause 1 — the vLLM bug was real and needed the nightly.
4. **Prefer FP8 attention (the §2 mixed recipe) over full W4A4** for a coherence-
sensitive seat. AEON passed every static gate (abliteration 4/4, surface 6/6, a
36k needle, 52% acceptance) and was still the lower-fidelity of the two.
Current primary gen: the mixed FP8-attention build on pinned vLLM nightly with
MTP, until the DavidAU Qwen3.8 lands. A W4+bf16 (W4A16) build would be higher
fidelity still (§1) at a prefill cost — an option if the mixed build ever proves
marginal.
### 3.7 ⭐ A LOADED MTP head can still corrupt output — Qwen3.8 multi-turn
§3.3 is about *losing* the head (0% acceptance, silent). This is the opposite and
worse failure: the head loads, acceptance looks healthy, single-turn output is
perfect — and then it **corrupts multi-turn conversations** once cumulative context
passes **~2,000 tokens**. The reply collapses in length *and* bleeds earlier turns
into the current answer (a "describe durian" reply that contained the Krebs-cycle
and winter answers from three turns back). Single-turn probes and the acceptance
gate (§5) **do not catch it** — it only appears as accumulated context grows.
Isolated 2026-08-16 (operator-confirmed), each step measured on a fixed 7-turn probe:
- **Not the serving gateway, not sampling, not repetition/template.** Identical
input gateway-vs-direct behaves the same; presence_penalty 1.5/0.5/0.0 all
collapse; higher temperature collapses harder; a conversation of *unrelated*
topics collapses at the same ~2k tokens as a repetitive one → it is context-
length-driven, not template lock-in.
- **Model-independent across every Qwen3.8-27B quant** (AEON W4A4, unsloth
FP8-attn, our in-house mixed) — so not a quant-brand or scheme artifact.
- **DECISIVE: same model + same conversation, MTP OFF → coherent through 4k+
tokens, zero bleed.** Toggle it back on → collapse returns. MTP is the cause.
**Qwen3.6-27B running the same `qwen3_5_mtp` method is CLEAN.** So the 3.6 MTP
head/graft is fine and the 3.8 one is not — suspects: the bf16 graft being subtly
wrong for the 3.8 head, or the vLLM `qwen3_5_mtp` impl diverging at `num_speculative_tokens=3`.
Open upstream question (queried dvalin/bil-smithy 2026-08-17).
**Rule: gate MTP on a MULTI-TURN coherence probe, not just single-shot acceptance.**
Run a 7-turn varied-topic conversation and watch turns past ~2k cumulative tokens
for length-collapse and cross-turn bleed.
**THE MITIGATION (resolved 2026-08-17): disable prefix caching, keep MTP.** The
corruption is gated on MTP × prefix-caching *together* (vllm#43559 / #47194) — with
`--no-enable-prefix-caching` the GDN cache runs in a mode where the buggy
partial-accept align-path is inert. Confirmed on our stack: AEON W4A4, MTP on +
prefix-caching off → the 7-turn varied series stays coherent through 3.9k tokens,
zero bleed, at **104.6 tok/s / 53.6% acceptance** — i.e. the FULL MTP speedup back
(vs ~half with MTP off), losing only prefix-cache reuse. The gen seat runs this
config as of 2026-08-17.
Things that do **not** work, ruled out: `num_speculative_tokens=1` (corruption is
depth-independent — reproduces at n=1 and n=2, deterministically probed upstream);
switching engine (vLLM / SGLang / llama.cpp mainline all share the GDN-rollback
bug — it is architectural). The proper upstream fix (vllm#51113) is in `main` /
`v0.27.2rc0` only — not in a stable release, so we hold at APC-off until it lands.
Two cross-frontier peers (dvalin/bil-smithy) confirmed the bug class and pointed
at the open symptom-twin issue #47087.
### 3.4 Toolchain version deadlocks
Both directions have burned us, so the resolution is: **use llm-compressor / compressed-tensors,
not nvidia-modelopt.**
- modelopt **0.45** ↔ transformers 5.12: `mtq.quantize` dies `TypeError: issubclass() arg 2 must
be a class` (modelopt registers transformers' `FusedMoE`, a *function* in 5.x, as an nn class).
- modelopt **0.43** doesn't fix it — it drags transformers back to 4.57, which cannot load
`qwen3_5` at all.
- modelopt's config API also trails the current model families by a version.
### 3.5 Vision tower and its configs
- Keep the **vision tower in `ignore`** (BF16). Only the LLM backbone gets quantized.
- The wrapper-class save **drops `preprocessor_config.json`** (and the video one). Without it the
seat crash-loops `Can't load image processor`. Restore from the source — and if the upstream repo
omits it, **reconstruct it from `processor_config.json`'s `image_processor` sub-dict**.
### 3.6 Memory and device placement (large models)
- **`device_map=None`/`"cpu"`, never `"auto"`.** `auto` fills GPU0 and OOMs during un-fusing;
constraining with `max_memory` then offloads to the *meta* device, which cannot be `.copy_()`d.
CPU-resident keeps every tensor real; the sequential pipeline still onloads per-layer to GPU.
- **Avoid mmap on `/tank`.** `safetensors.safe_open()` mmaps a whole shard; on ZFS a 50 GB shard
ENOMEMs regardless of free RAM (MAP_SHARED never consults the commit limit). Read with plain
`read()` + `load(bytes)`, one shard cached at a time.
- **`vm.overcommit_memory=1`** on ana-ml2 (durable via `playbooks/ana-ml2-overcommit-memory.yaml`).
### 3.9 ⭐⭐ A sharded forward can be silently WRONG — never trust `device_map="auto"` for activations
Splitting **Qwen3.8-27B (Qwen3_5 hybrid)** across the two Blackwells with `device_map="auto"`
produces a model that loads clean, reports no error, and computes **garbage**: the residual stream
collapses to **exactly zero** a couple of layers past the GPU0→GPU1 boundary, and the logits decode
to rubbish (`'8'`, `'�'`, `'b'`). Every layer *below* the boundary stays healthy, deterministic, and
bit-identical to a single-GPU run — which is what makes it so dangerous. A capture that reads a
low layer looks perfectly plausible and is fine; one that reads a high layer is reading zeros, and
nothing in the pipeline says so. Measured 2026-08-20 (§9 Cold-Fusion).
**Rule: any workload that reads activations — refusal-direction capture, calibration, activation
statistics, PPL — must run on ONE device.** Sharding is for *storage*, and it is only safe when you
consume the model's final output through an engine that was built for it (vLLM does TP correctly;
`device_map="auto"` in transformers is not the same thing). If it does not fit on one card, shrink
the model, not the guarantee: **truncating the decoder to N layers is exact** for any activation
read at a layer < N (a causal stack's layer-N state cannot depend on layers above N), and it is
cheap — verified by reproducing the full model's layers 18/20/22/26 bit-for-bit.
**Gate it, don't remember it.** Assert single-device residency and zero offload before the forward:
```python
dmap = getattr(model, "hf_device_map", {}) or {}
gpus = {str(v) for v in dmap.values()} - {"cpu", "disk"}
offloaded = [k for k, v in dmap.items() if str(v) in ("cpu", "disk")]
if len(gpus) > 1 or offloaded:
sys.exit("residency gate FAILED — sharded/offloaded forward reads garbage")
```
### 3.10 ⭐⭐ `PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True` corrupts retained tensors
On torch 2.12+cu130 / Blackwell, tensors that **outlive their allocation** come back corrupted with
this flag set: captured hidden states carried Inf / NaN / zeros that **moved between bit-identical
forwards** (same input, same weights → a different layer corrupted each time). Unset, the identical
forwards are exactly reproducible. Several runbooks recommend this flag for headroom on large
loads; for anything that *keeps* activations it buys corruption.
Two tells that distinguish this from a real numerical blowup, both worth knowing because they
generalise: a genuine blowup **propagates** to later layers and is **deterministic**. Corruption
does neither — downstream layers were finite and consistent, and the affected layer moved run to
run. **If a "NaN" fails to propagate, stop debugging the math and start debugging memory.**
Corollary: **do not read `output_hidden_states=True` off a returned object** on a large multi-device
load. Take what you need *during* the forward with a `register_forward_pre_hook` that clones to CPU
immediately — it closes the reuse window and never retains a `[B, seq, hidden]` tensor per layer, so
it is cheaper than the thing it replaces.
### 3.11 Determinism is a necessary check, not a sufficient one
Both defects above were found by the cheapest possible test — **run the same input twice and diff**
— which no amount of eyeballing plausible-looking numbers would have caught. Add it to any
activation-reading pipeline. But note the trap that followed: after fixing the allocator, the run
went perfectly "deterministic" *because the corrupted layers were now stably zero*. Pair the
determinism check with a **magnitude** check (residual norms should grow smoothly with depth; an
exact 0.0 mid-stack is impossible) and, where you can, a **coherence** check (generate 40 tokens and
read them).
### 3.12 ⭐⭐ You cannot free a 27B model in-process — give each model its own process
Any A/B that loads two large checkpoints in sequence (KL, logit diffing, teacher-vs-student)
will try to release the first before loading the second. **On this stack, it does not work.**
Measured 2026-08-20 on Qwen3.8-27B bf16, free VRAM after each attempt:
| teardown | free VRAM |
|---|---|
| `del model` + `gc.collect()` + `torch.cuda.empty_cache()` | 45,287 MiB |
| same, with the model confined to an inner frame that exits | 45,287 MiB |
| **the process exits** | **97,247 MiB** |
The ~51,300 MiB of weights stayed resident through both in-process teardowns. The first
run survived only because **PyTorch's allocator hit OOM on the second load, ran a collection
itself, and retried** — the second model landed by rescue, not by design. That is not a
release strategy: on an architecture where a silent CPU offload does not raise (§3.9), the
day the retry does not fire you get confident garbage instead of an error.
**Do this instead:** one process per model, hand results to disk between them
(first-token log-probs for a 250k vocab are ~715 MiB per model — nothing), and gate each
stage on free VRAM *before* the load. Reference implementation:
`services/coldfusion-abliteration/kl_divergence.py` (`--stage ref|cand|score`).
Two gate corollaries learned in the same session:
- **⭐ A residency gate that reads `hf_device_map` cannot fail.** The map is **empty**
whenever transformers puts the whole model on one device, so the check reports
"unsharded" both when everything is fine and when there is nothing to inspect. Read
`{p.device for p in model.parameters()}` — ground truth in every case. (Generalises
[[feedback_assert_effective_value_not_substring]]: presence of a passing check is not
evidence of a check that can fail.)
- **⭐ Size VRAM from the checkpoint's own headers, never from a remembered figure.** A
runbook carried "bf16 is 50 GB"; the real number was 50.10 **GiB** = 51,300 MiB of
text-only weights. That 3.7 GB unit error is exactly the difference between "stop one
co-tenant" and "stop both", and it cost an aborted window. Sum the safetensors header
offsets (excluding tensors the loader class won't instantiate — vision, MTP); read only
the 8-byte length prefix + JSON header, never `safe_open`, which mmaps the whole shard
and ENOMEMs on ZFS (§ *Avoid mmap on `/tank`*).
### 3.13 ⭐⭐ The observer you ASKED for is not necessarily the observer you GOT
`quant_mixed_nvfp4.py` sets `observer="imatrix_mse"` on the NVFP4 W4A4 group. It has
**never once been used.** llm-compressor looks for importance data, finds none, and
silently degrades:
```
_get_validated_importance | WARNING - imatrix_mse: no importance data available.
Falling back to uniform MSE.
```
Confirmed on the 2026-08-20 09:59 incumbent quant **and** the 22:45 Heretic-300
quant; `find /tank/aimodels -iname "*imatrix*" -o -iname "*importance*"` returns
nothing. Every NVFP4 build in the fleet has run uniform MSE while the recipe claimed
importance weighting.
**Why it went unseen for months:** the warning scrolls past inside a tqdm progress
bar during a ~20 minute quant. It is only visible if you read the log while it runs.
**The generalisable rule, which is bigger than imatrix.** A quantizer, optimiser or
observer that *silently falls back to a weaker default* is a whole class of invisible
quality loss — the config is accepted, nothing errors, the artifact benchmarks
plausibly, and you never learn you got the cheap path. So:
- **Grep the quant log for `WARNING`, `Falling back`, `not available`, `ignoring`
before trusting an artifact.** Make it a step, not a habit.
- **Assert the effective setting, never the requested one** — the same rule as
[[feedback_assert_effective_value_not_substring]], applied to quantizer internals
rather than config files.
- If the fallback turns out to be unavoidable in your toolchain version, **change the
recipe to say what it actually does.** A recipe line that silently lies is worse
than one that admits a limitation.
⚠️ **Do not "fix" this by assuming an imatrix would help.** Verify first that your
llm-compressor version can consume an externally supplied importance matrix at all,
and in what format. Parked as `park/nvfp4-recipe-asks-for-imatrix-mse-but-silently-2`
(id 42) with the calibration corpus that would feed it.
✅ **Comparisons already made remain valid.** Because *every* build shares the
fallback, the incumbent-vs-candidate A/Bs (47.2% acceptance, PPL 6.910, and the
2026-08-20 Heretic-300 build) are apples-to-apples. This is unrealised upside, not a
correction to past numbers.
### 3.14 ⭐⭐ Calibration BAKES a truncation cap into the shipped tokenizer
**Symptom (on a newer transformers, at startup, on a vision model):**
```
ValueError: Mismatch in `image` token count between text and `input_ids`.
Got ids=[2047] and text=[16384]. Likely due to `truncation='max_length'`.
```
The engine never serves a request. The number in `ids=[…]` is your **calibration seqlen minus
one**, which is the tell.
**Cause — an in-place mutation you never wrote.** Calibration tokenizes like this:
```python
tok(b["text"], truncation=True, max_length=seqlen, add_special_tokens=False)
```
For a **fast** tokenizer that call does not just return ids — it **mutates the Rust backend's
truncation state in place**. A later `tok.save_pretrained(out)` then persists it:
```json
"truncation": {"direction": "Right", "max_length": 2048, "strategy": "LongestFirst", "stride": 0}
```
The source model has `"truncation": null`. **You shipped a tokenizer that clamps every prompt at
the calibration length, permanently.**
**Why it hid for months.** Older transformers does not enforce the text-vs-ids count check, so
the cap sits latent — the model serves, gates pass, vision works, nothing logs. It only detonates
when you bump the image, and then it presents as a *vision* bug at startup with no mention of
tokenizers. It also caps the effective image resolution long before it kills the seat: at a 2048
cap the largest servable image is ~1448×1448, because `(edge/patch)² / merge²` image tokens must
fit under it.
**The fix — never save the calibration tokenizer.** Re-read a pristine one from the source:
```python
from transformers import AutoTokenizer as _AutoTokenizer
_AutoTokenizer.from_pretrained(a.model, trust_remote_code=True).save_pretrained(a.out)
```
then **assert** it, because this is exactly the class of defect that returns silently:
```python
if json.load(open(f"{a.out}/tokenizer.json")).get("truncation"):
raise SystemExit("FAILED CHECK: saved tokenizer carries a truncation cap")
```
Both live in `quant_mixed_nvfp4.py` as of 2026-08-22.
**Audit any build predating that.** One line per model:
```bash
python3 -c 'import json,sys;print(json.load(open(sys.argv[1]+"/tokenizer.json")).get("truncation"))' <model_dir>
```
Measured 2026-08-22 — every mixed-NVFP4 build from this pipeline was affected, and the two live
ones were corrected in place (backup `tokenizer.json.bak-truncation-20260822`; only the
`truncation` field changed, vocab and `added_tokens` byte-identical):
| build | truncation as found |
|---|---|
| `qwen38-27b-orcarouter-nvfp4-mixed` (live `gen`) | **2048** → fixed |
| `mog-sec-27b-nvfp4-mixed` (live `sec`) | **2048** → fixed |
| `qwen38-27b-heresy-nvfp4-mixed` (retired) | 2048, left as-is |
| `G4-MeroMero-v2-31B-NVFP4A16` (different pipeline) | `null` ✓ |
| `mog-sec-27b-bf16` (source) | `null` ✓ |
**Editing it is safe on a running seat** — vLLM reads the tokenizer at startup and holds its own
copy, so the fix lands on the next restart with no disruption.
**The general lesson, which is the transferable part:** this is the third defect in this playbook
where *the artifact carries config authored against an older transformers and a newer one starts
enforcing it* (see also the Gemma-4 heterogeneous `head_dim`). **Treat "we bumped the image" as a
config-compatibility event, not just a version change** — and prefer saving artifacts re-read
from the source over saving objects the pipeline has touched.

## 4. Pipeline shape
### 4.1 Prove the targets before spending GPU time
Enumerate module names from the safetensors index and check your regexes against them: **zero
overlap between groups, and the union covers every layer you intended.** This is free, takes
seconds, and catches a mis-scoped regex that would otherwise surface as a mystery quality
regression hours later. Reference: `services/gen-seat-mixed-quant/validate_targets.py`.
### 4.2 Quantize
Calibration data matters for `imatrix_mse` + static activation observers. We use
`/tank/aimodels/heretic2-nvfp4-work/production_calib_512.jsonl` (512 chat samples, RP/GM-flavoured
— appropriate for our seats). 256 samples @ 2048 tokens ≈ 20 min for a 27B on one Blackwell.
### 4.3 The mandatory post-steps
Never optional, always in this order, and the last one **verifies rather than assumes**:
1. Graft `model-mtp.safetensors` + register its tensors in the output index.
2. Restore `preprocessor_config.json` / `processor_config.json` / `video_preprocessor_config.json`.
3. **Re-inject `re:^mtp.*` into `quantization_config.ignore` and confirm it is there** (§3.3).
4. **Confirm the saved `tokenizer.json` has `truncation: null`** (§3.14) — calibration mutates the
fast tokenizer in place and `save_pretrained` bakes the cap in. Latent on an older
transformers, fatal on a newer one.
Reference implementation: `services/gen-seat-mixed-quant/post_quant.py`.
### 4.4 Test on a temp port, never on the live seat
Serve the candidate on an alt port with the live seat's **exact** flags, run the gate (§5), and
only then flip `.env`. Keep the previous build on disk; rollback is one `.env` line.
---
## 5. The acceptance gate — and how measurement lies to you
Speed alone does not justify cutting over a shared seat. Gate on **all** of: decode tok/s, MTP
acceptance, perplexity, a behavioural surface test, and — for an abliterated model — that the
abliteration survived.
**Three ways the numbers have lied to us. All three produced confident, wrong results.**
1. **Prefix caching fakes both speed metrics.** A fixed prompt returns byte-identical timings run
after run; you are measuring cache, not compute. Worse for prefill: a *seeded* nonce
regenerates the previous run's prompts verbatim and reads **~41k tok/s of cache-hit instead of
~5k of real prefill**. Use a fresh unseeded nonce per request; never seed a cache-buster.
2. **`prompt_logprobs` are garbage while speculative decoding is on** — ~uniform over the vocab
(median rank ~10⁵; " Paris" after "The capital of France is" ranked 69698). **Perplexity must be
measured on a seat served without `--speculative-config`,** on both sides of the comparison.
3. **A 0600 `.env` makes `docker compose` silently no-op.** Without `sudo` it fails
`permission denied` reading `.env`, **leaves the old container running**, and reports success —
producing a full page of "benchmark results" that were just the unchanged baseline.
**Hard-verify the change landed against `docker inspect …Config.Cmd`.**
**Re-measure the baseline before believing a target.** The 2026-08-15 handoff quoted ~68 tok/s;
cache-busted, the incumbent was already doing 80.1 — essentially the *target* of the work queued
against it. Had that not been re-measured, doing nothing would have looked like a 20% win.
**Cheap shortcut worth taking first:** if a reputable published quant of the same architecture is
already on-box (or is a small pull), **serve it as a probe and measure it** before committing
hours to your own. It answers "is this gain even real?" in ten minutes *and* hands you the recipe.
Harness: `services/gen-seat-mixed-quant/bench/` — `quickbench.py` (decode + acceptance),
`prefill_bench.py`, `eval_quality.py` (PPL + abliteration), `surface_test.py` (chat, vision, tools,
thinking split, long-context needle, streaming), `serve_probe.sh`.
---
### 5.1 ⭐⭐ Acceptance is not throughput — always run the DEPTH control
**Measured 2026-08-22**, same instrument (vLLM's own `spec_decode` counters, delta over a fixed
workload, temp 0), same target, same engine:
| config | accepted tok/forward | throughput |
|---|---|---|
| MTP k=3 | 2.753 | 114.9 tok/s |
| MTP k=7 | **3.041** ⬆ | **74.0 tok/s** ⬇ |
**Raising `num_speculative_tokens` improved acceptance and destroyed throughput.** Reporting
acceptance alone would have recommended a 36% regression.
**Why:** a single-module MTP head (`mtp_num_hidden_layers: 1`, one `mtp.layers.0`) has no depth
of its own — vLLM runs it **autoregressively**, so k draft tokens cost **k sequential forward
passes**. Past a shallow depth the drafting cost exceeds what the extra accepted tokens save.
Check `mtp_num_hidden_layers` before assuming depth is cheap.
**The rule: when comparing two speculative methods, match k, or you are measuring depth rather
than method.** A parallel-drafting drafter (DFlash2 and kin, which propose a whole block in one
pass) at k=7 versus an autoregressive MTP at k=3 is not a method comparison — the depth control
is what separates them. In our case the control showed most of the apparent acceptance win was
depth, while the *throughput* win was real and came from parallel drafting, not better drafts:
our MTP was **better at position 0** (79.6% vs 75.4%) and still lost overall.
**Corollary — report both, always.** Acceptance rate, mean accepted length, and end-to-end
tok/s. Any one of the three alone can point the wrong way.
---
## 6. Hardware and co-residency
- **ana-ml2 = Blackwell (sm_120)**, 2× 96 GB. Native FP4 + FP8. Hopper-exact code paths
(`match_exact=True` on sm90) are **closed** here — do not plan around them.
- **irv-ml1 = Ampere (sm_86)**, 3090 + A6000. **No native FP8/FP4** — 4-bit there is a VRAM saving
only, not a speed win. Don't port a Blackwell scheme over and expect the throughput.
- **GPU co-residency is a zero-sum budget, and a *smaller* model can break its neighbour.**
`gpu-memory-utilization` is a fraction of the *whole card*, so when new weights are smaller the
seat absorbs the slack as extra KV rather than releasing it. That is exactly how a −5.2 GB
requant left the co-resident seat **0.18 GiB** short and crash-looping. **After any requant,
re-check both seats' budgets** and hand the space back explicitly.
---
## 7. Superseded claims — do not follow these
Old docs stay for their history, but these specific claims are **false now** and will cost you a
day if followed:
| claim | where | status |
|---|---|---|
| "Use modelopt, NOT compressed-tensors — compressed-tensors can't load the BF16 MTP head, 0% acceptance" | `docs/runbooks/heretic2-nvfp4-mtp-seat.md` §landmine 2 | **SUPERSEDED 2026-08-14.** The 0% was the missing `re:^mtp.*` ignore (§3.3), not the format. compressed-tensors + the ignore gives 47.7–83.2% acceptance, live. Use compressed-tensors. |
| "Abliteration desyncs the MTP head → uncensored models can't do MTP" | earlier auto-memory | **SUPERSEDED 2026-08-14.** A modest abliteration preserves MTP (83.7% at bf16). Test MTP on **bf16 first** to isolate abliteration from quant/graft confounds — and isolate before deleting a 50 GB source. |
| "NVFP4 W4A4 is infeasible, no 4-bit wins both axes, FP8 is the Blackwell answer" | `reference_nvfp4_w4a4_granite_infeasible` | **NARROWED.** True for *uniform* W4A4 (measured on Granite-8B at 30k ctx). W4A4 on bulk MLPs **with FP8 on attention and late layers** is fine and is the current default (§2). |
| "transformers' Qwen3.5 DeltaNet linear-attention NaNs in bf16 without causal-conv1d; it is precision-driven cancellation and fp32 resolves it" | `services/coldfusion-abliteration/README.md`, `persistent-memory.d/2026-08-20-coldfusion-abliteration-capture.md` | **SUPERSEDED 2026-08-20.** Precision was never the variable. The NaN came from **multi-GPU sharding** and **`expandable_segments`** (§3.9, §3.10); fp32 only made it rarer, which is worse than failing. On one GPU with a plain allocator, **bf16 is exactly deterministic through all 64 layers and generates coherent prose** — at 50 GB and 4.3× the throughput of the 111 GB fp32 it replaced. |
---
## 8. Measured negatives — don't re-chase
- **`num_speculative_tokens` = 3 is optimal** on the Qwen3.8-27B seat. Swept: n=2 → 77.1,
**n=3 → 80.1**, n=4 → 78.7, n=5 → 75.9 tok/s. Higher n trades acceptance for draft width and
loses. Re-sweep only if the drafter architecture changes.
- **Uniform W4A4** — see §7 row 3.
- **Dense-VL as the anatomy judge** — A/B'd, MoE retained. Don't re-propose.
---
## 9. Worked examples
Per-model artifacts. Read for *how a specific model went*, not for the general lessons — those are
above, and where the two disagree, **this file wins**.
| artifact | what it is |
|---|---|
| `services/gen-seat-mixed-quant/` | **current reference.** Mixed NVFP4+FP8 on Qwen3.8-27B-Uncensored: scripts, acceptance harness, raw measurements. |
| `stacks/gen-seat/README.md` | the live `gen` seat (7 LiteLLM aliases) |
| `stacks/meromero-charrp/README.md` | Gemma-4 seat — the **tool-call/reasoning-parser** trap (a parser default that returns null `content` for all prose) |
| `services/heretic2-nvfp4-quant/` | modelopt-format MTP seat — historical; see §7 before following it |
| `tools/mistral-small4-nvfp4/` | MoE + native-convert path; source of §3.6 |
| `docs/pfi/recommended-model-settings.md` | serve-time sampler/flag defaults (not quant) |
**A new model just dropped and needs requanting?** §1 → §2 → §4 → §5. Skim §3 first; it is the
part that costs hours.

# Canonical sampler defaults — PFI/VastBlue LiteLLM gateway seats
**Applied:** 2026-07-08 · **Gateway:** `ana-docker:4000` · **Config:** `stacks/litellm/conf/config.yaml` → `/opt/docker/conf/litellm/config.yaml`
Canonical high-quality sampler defaults for the four model seats, **derived by
dvalin-smithy-dev** (full rationale + sources: `dvalin-smithy/hoard-drafts/pfi-gateway-sampler-defaults-20260708.md`),
**triaged + A/B-validated by infra-ops**, and wired into the gateway. These are the
gateway *defaults*; callers may override per request.
Optimized for **output / prose quality** (not throughput or determinism).
## Engine surfaces
- **gen / gen-reasoning** — vLLM 0.24 (OpenAI sampler surface). No native DRY/XTC → anti-repetition via `presence_penalty`. Thinking split via `chat_template_kwargs.enable_thinking` on distinct `--served-model-name`s (avoids the shared-config-mutation footgun).
- **char-rp / char-rp-reasoning** — llama.cpp / llama-server (supports `min_p`, `top_k`, DRY, XTC, dynatemp). `min_p` + `top_p` do the tail work; `top_k 0` disables top-k.
## The four seats (applied values)
### 1. gen — Qwen3.6-35B-A3B heretic (vLLM, non-thinking)
Also governs **summarizer-large** (shares the same `qwen3.6-27b-aeon` @ :8015 deployment → kept identical).
| param | value |
|---|---|
| temperature | 0.7 |
| top_p | 0.80 |
| top_k | 20 |
| presence_penalty | **1.5** |
| repetition/frequency | 1.0 / 0.0 |
| enable_thinking | false |
*Source:* Qwen3.6 README instruct/non-thinking rec. *Change:* presence_penalty 1.0 → 1.5.
### 2. gen-reasoning — same model (vLLM, thinking)
| param | value |
|---|---|
| temperature | **1.0** |
| top_p | 0.95 |
| top_k | 20 |
| presence_penalty | **1.5** |
| repetition/frequency | 1.0 / 0.0 |
| enable_thinking | true |
*Source:* Qwen3.6 README **general** thinking profile (NOT the temp-0.6 coding sub-profile — the prior default was that coding profile by mistake). *Changes:* temperature 0.6 → 1.0, presence_penalty 1.0 → 1.5. Reasoning is verbose (~9k chars) → callers set generous `max_tokens` (catalog default 32768). Optional per-route coding override: temp 0.6 / presence 0.0.
### 3. char-rp — Magidonia-24B-v4.3 (llama.cpp, non-thinking prose RP)
| param | value |
|---|---|
| temperature | **1.1** |
| top_p | 0.95 |
| min_p | **0.10** |
| top_k | 0 (disabled) |
| repetition/DRY/XTC | **off** |
*Source:* dvalin canonical (Mistral-Small RP prose) **A/B-validated by infra-ops** on the live serve. *Changes:* temp 1.0 → 1.1, min_p 0.03 → 0.10. **min_p 0.10 richened imagery vs 0.03** with no incoherence at temp 1.1. **repeat_penalty 1.05 was REJECTED** — in the A/B it injected a stray markdown title into a grief scene; rep-style penalties hurt Drummer/Magistral RP creativity (matches the model card and dvalin's own note). Alt prose model: `MS3.2-PaintedFantasy-v4.1-24B` (swap via the `char-rp-gguf` stack `.env`).
### 4. char-rp-reasoning — Qwen3.5-27B-Deckard-PKD (llama.cpp, managed-reasoning RP)
| param | value (request-level) |
|---|---|
| temperature | 1.0 |
| top_p | 0.95 |
| top_k | 40 |
| min_p | **0.05** |
| presence/repetition | **off** |
| DRY | **0.8 server-side** (base 1.75 / len 2, dry-after-temp) — not a request param |
| reasoning-budget | 400 (server-side) |
*Source:* dvalin-CONFIRMED canonical 2026-07-08 (thread 01KX1Y7P). **Corrected 2026-07-09:** this seat had lagged on QwQ-RpR-v4 — the A/B on 2026-07-08 replaced it with **Deckard-PKD-Heretic i1-Q5_K_M** (DavidAU, Qwen3.5-27B, :8018); the live gateway was always Deckard. Deckard won on brokkr's frozen scorer (0/30 loops, 0/30 refusals) over RpR-v4 (1/30 loop, forbids DRY) + Pantheon-27B (7/30 refusals). Reasoning ON server-side (`--reasoning on`, budget 400); CoT surfaces in `reasoning_content`, clean prose in `content`. Tuning ladder: flat prose→min_p 0.08, loops→DRY 0.9, over-damped→DRY 0.6/off. **Do NOT import RpR/QwQ sampler rules** (different family — QwQ hated DRY; Qwen3.5 benefits from it).
## Changing a default
Edit the seat's `litellm_params` in `stacks/litellm/conf/config.yaml`, `scp` to
`/opt/docker/conf/litellm/config.yaml` on ana-docker, `docker restart litellm`.
(`gen` and `summarizer-large` must change together — same deployment.)

# Ops lessons playbook — the transferable ones
The operational sibling to `model-quantization-playbook.md`, and it exists for the
same reason: hard-won lessons kept dying inside per-host runbooks where nobody
finds them until they have already repeated the mistake.
**What belongs here:** a lesson that would bite identically on a different host.
**What does not:** anything true only of one machine — that stays in
`servers/<host>/README.md` or the relevant runbook.
Each entry states the rule, what it cost, and how to recognise the situation.
When an entry turns out to be wrong, add a dated row to § Superseded rather than
quietly editing it, so older references stop misleading people.
---
## 1. `mount --rbind` into a chroot needs `--make-rslave`
**Rule:** after every `mount --rbind /x /target/x`, immediately
`mount --make-rslave /target/x`. Guard on it — refuse to proceed while
`findmnt -o PROPAGATION` reports `shared` for any chroot bind.
**Why:** on a systemd host `/` has *shared* mount propagation, so an `--rbind`
shares propagation with the original. A later `umount -R` of the chroot copy
**propagates back into the live system** and unmounts the real `/sys/fs/cgroup`,
`/dev/pts`, `/dev/shm`. `--make-rslave` makes propagation one-way (host → chroot),
so teardown cannot reach back.
**Cost:** an unplanned production outage on esh-pve-nas, 2026-08-18.
**Recognising it — and this is the valuable part, because it does not look like
what it is.** With cgroup2 gone, `systemd-logind` cannot create sessions, which
produces a host that:
- answers ping and accepts TCP
- **completes SSH authentication**
- keeps serving from daemons already resident in memory (a PVE box returned clean
HTTP 401s from `pveproxy` throughout)
- **hangs on every new `exec`** — including `/sbin/reboot`, so a reboot issued to
fix it never runs
That is an almost perfect impostor of **failing root-disk I/O**, and it was
misdiagnosed as exactly that. If you see "daemons answer but nothing new can
start," check `findmnt /sys/fs/cgroup /dev/pts /dev/shm` before you suspect the
disk.
**Recovery needs no console.** Exec succeeds in brief windows; loop an idempotent
remount until one lands:
```sh
mountpoint -q /sys/fs/cgroup || mount -t cgroup2 none /sys/fs/cgroup
mountpoint -q /dev/pts || mount -t devpts devpts /dev/pts -o gid=5,mode=620,ptmxmode=666
mountpoint -q /dev/shm || mount -t tmpfs tmpfs /dev/shm -o mode=1777,nosuid,nodev
```
Then `systemctl reset-failed`. Full narrative:
`docs/runbooks/esh-pve-nas-boot-migration.md` § The mount-propagation incident.
---
## 2. A reboot is not confirmed until the host is observed DOWN
**Rule:** poll for the host's *disappearance* first, then for its return. Never
infer a reboot happened because the host answers.
**Why:** "never went down" and "went down and came back quickly" are
indistinguishable if you only watch for it to answer. On 2026-08-18 a
down-detector never once reported the host down; that was read as a fast reboot
when in fact `/sbin/reboot` could not exec and the machine never rebooted at all.
Everything diagnosed afterwards was built on that false premise.
**The cheap confirmation** is the boot timestamp — `uptime -p`, or the last
`dmesg` timestamp. A `dmesg` tail whose last entry sits at `[12114881]` seconds
is telling you the machine has been up 140 days, whatever else you believe.
```sh
down=0
while :; do
if ping -c1 -W1 "$H" >/dev/null 2>&1; then
[ $down -eq 1 ] && break || echo "up (not yet down)"
else down=1; echo "DOWN confirmed"; fi
sleep 2
done
```
---
## 3. Assert the effective value, not the presence of a substring
**Rule:** a verification step must check what the system will actually *use*, not
that the correct-looking string appears somewhere in a file.
**Why:** the check "does `root=ZFS=nvme/ROOT/pve-1` appear in `grub.cfg`?" passed
happily while **every menu entry was still broken** — the correct value had been
appended by a drop-in, and the broken pool-less value was still first on the line.
Since the kernel takes the *last* `root=`, only a check that extracts the last one
per entry and compares it against a known-good set proves anything.
```awk
/^[[:space:]]*linux[[:space:]]/ {
r=""; for (i=1;i<=NF;i++) if ($i ~ /^root=/) r=$i;
if (r != "root=ZFS=pool/dataset" && r != "root=/dev/mapper/x") { print "BAD: " r; bad=1 }
} END { exit bad?1:0 }
```
Generalises well beyond GRUB: last-wins config keys, layered drop-ins, anything
with override semantics. **Grep proves presence; only evaluation proves effect.**
---
## 4. Ask the server who its clients are
**Rule:** before taking a service down, enumerate its dependents **from the
service**, not from documentation.
**Why:** a runbook named two NFS dependents. `ss` on the NFS server found five —
including a database VM with a `hard` mount and no SSH access. Documented
dependent lists rot silently because nothing forces them to be updated when a new
client mounts.
```sh
# NFS server: who is actually connected right now
ss -tnH state established '( sport = :2049 )' | awk '{print $4}' | sed 's/:[0-9]*$//' | sort | uniq -c
```
Equivalents worth reaching for: `ss -tnp` by port for any service, `docker ps`
plus mount inspection for bind-mount consumers, `pvesm status` for storage.
**Corollary on `hard` NFS mounts:** a `hard` mount with **no active user** blocks
and then resumes when the server returns — that is what `hard` is for, and it came
through read-write across two server reboots. The disaster case is a *process
actively using* the mount. So quiescing means stopping the consumers, not
necessarily unmounting; and when unmounting is expensive or risky (a host you
cannot SSH to), leaving an idle hard mount is often the lower-risk branch.
---
## 5. The scoped-looking command can be the dangerous one
**Rule:** when a command names one member of a set, ask what happens to the
members it does not name.
**Why:** `zpool set cachefile=/etc/zfs/zpool.cache nvme` looks careful and
narrow. It is not: populating a cachefile flips the host from import-by-scan to
import-by-**cache**, so a cache containing only `nvme` leaves `ssd` and `tank`
unimported at boot. On a host whose NAS container had twelve bind mounts spanning
all three pools, that empties every export. The broad form — setting it on all
three — is the safe one.
---
## 6. Long uptime hides breakage; a forced look is worth more than it seems
Not a rule so much as a calibration. One migration on a pair of hosts with 20
weeks of uptime surfaced, none of it caused by the work:
| found | dead for |
|---|---|
| `pvestatd` SEGV'd (node rendered dark in the UI, otherwise healthy) | 82 days |
| a `vzdump` hung at 0% of 256 GiB, holding `lock: backup` | 126 days |
| a VM stuck in QEMU `prelaunch` behind that lock | ~4 months |
| a VM silently missing `sshd`, `mongod` and its guest agent | unknown |
| an undocumented 2-node cluster, and 3 undocumented NFS clients | always |
**When a host has not been rebooted or audited in months, budget for finding
unrelated breakage, and treat that as part of the value rather than as scope
creep.** Several of these were invisible precisely because nothing had forced
anyone to look.
Corollary: **a cosmetic-only symptom can hide for a very long time.** Nothing
alerted on `pvestatd`; its sole symptom was a grey tile in a UI nobody had reason
to stare at. Worth a watchdog on anything whose failure mode is "the dashboard
quietly stops being true."
---
## 7. Verify a "this will break X" premise before building around it
**Rule:** when a risk is asserted but never tested, test it — especially before it
justifies a body of work.
**Why:** fleet IPv6 work was justified largely by "ESH fiber behind CGNAT will
break Site Magic on IPv4." The fiber cutover tested it for free: Cox was
unplugged, ESH failed over to 5G on `192.168.200.111` — **RFC1918, double-NAT,
no inbound path, strictly worse than CGNAT** — and the tunnel held, carrying real
traffic to all four ESH hosts.
The mechanism was discoverable in advance and made the outcome predictable:
Site Magic is **WireGuard**, and the far side (NH3) has a public endpoint, so the
NAT'd side dials out and never needs reachability. Ten minutes of reading the
device config would have graded the risk correctly.
**How to apply:** for any "X will break Y" belief, ask what protocol Y actually
uses and which side must be reachable. NAT breaks *inbound* reachability; it does
not break outbound-initiated tunnels with keepalives. Beliefs that gate real work
deserve a test or an explicit "untested" label — and when they do get tested,
record the result where the belief lived, not only where the test happened.
**Related:** Site Magic has **no WAN binding** — `magic_site_to_site_vpn` on the
gateway is just `enabled` plus a keypair, peers orchestrated in the UniFi cloud.
It rides whichever uplink is active, so the only lever is failover priority, and
that moves *all* site traffic rather than just the tunnel.
---
## 8. A result proven for one protocol does not transfer to another
**Rule:** when a test clears a risk, state **which mechanism** it cleared it for,
and check whether every affected system shares that mechanism.
**Why:** proving that NAT does not break **Site Magic** (WireGuard, outbound-dialed
to a public peer) I wrote up as "no addressing outcome threatens the inter-site
tunnel." But the fleet has *two* inter-site links with opposite NAT behaviour, and
the other one — **IPsec** to the colo FortiGate — was **already broken at that
exact moment**, traffic leaking unencapsulated to the carrier. The operator caught
it; the test I had just run would have caught it too, had I run it against both
links instead of one.
**How to apply:** ask what property made the test pass — here, "outbound-initiated,
peer needs no inbound reachability" — and then ask which systems *lack* it. IPsec
site-to-site pins a peer IP and expects a routable address; WireGuard does not.
Same NAT, opposite outcome. Enumerate the affected set before generalising, and
name the mechanism in the conclusion so the scope is visible to the next reader.
---
## 9. IPsec to a NAT'd site: dialup peer + NAT-T, and you cannot convert in place
**Rule:** a site-to-site IPsec tunnel to any endpoint that might sit behind NAT
needs **`type dynamic`** (dialup responder) **and `nattraversal enable`**. Both.
Neither alone is sufficient.
**Why:** ESH↔colo died the moment ESH stopped having a public IP. Two independent
causes, and the second was invisible until the first was investigated:
| setting | broken tunnel | working tunnel |
|---|---|---|
| `type` | `static`, `remote-gw 70.181.90.232` (a dead address) | `ddns` |
| `nattraversal` | `disable` | `disable` — but NH3 is **publicly addressed**, so it never mattered |
The static peer IP is the obvious failure. The subtle one is that **`nattraversal
disable` would have kept the tunnel down even with the correct peer IP**, because
ESP cannot traverse NAT without UDP-4500 encapsulation. A "just re-pin the IP"
fix would have failed and looked mysterious.
⚠ **FortiOS refuses `set type dynamic` on an existing tunnel** — *"Cannot change
tunnel type once configured"*, with a clean rollback. So the fix is not an edit.
**Prefer building the replacement ALONGSIDE the broken one, not recreating it.**
Deleting a phase1 cascades into its phase2, its static routes and every policy
referencing the interface — on the affected box that was 1 + 2 + 10 objects.
A new `phase1` + `phase2` + one route + two consolidated policies is additive,
leaves the old config intact as rollback, and cannot break what still works.
**Confirming it worked** — the tunnel summary line says everything:
```
'ana-eshudm-dyn_0' 97.170.236.56:4500 selectors(total,up): 1/1
^^^ _0 = dialup child ^^^ carrier IP ^^^ :4500 = NAT-T
```
`_0` means the peer was accepted without being known in advance; `:4500` means
NAT-T is carrying ESP; the address is the carrier's, which could never have been
pinned. And traceroute drops from "8 hops wandering the carrier" to "gateway →
peer → destination".
⚠ **Residual fragility on the UniFi end.** The UDM's `ipsec_local_ip` must hold a
literal address — `""` is rejected with `api.err.InvalidPayload` — so it still
needs updating whenever that site's WAN address changes. The gateway end is now
address-agnostic; the UniFi end is not.
---
## 10. IPv6 collapses two independent exposure controls into one, and it fails open
**Rule:** before enabling IPv6 on any segment carrying real hosts, write explicit
default-deny inbound policy for that segment **and verify it from off-net**.
Reading the ruleset is not verification.
**Why — the asymmetry, which is the part worth internalising.** Under IPv4 with
NAT, exposing an internal host required **two** affirmative acts: a DNAT/port
forward *and* an accept rule. Miss either and the host stays dark. There is no
v4 misconfiguration that accidentally exposes an internal host, because without
the translation there is no path at all. NAT was load-bearing security whether or
not it was designed as such.
Under IPv6 the path exists inherently — the address is routable from birth. The
firewall is now the *only* control, so two independent things that both had to
succeed become one thing that must not fail. **The failure mode inverts from
fail-closed to fail-open.**
**Concrete ways it bites:**
| failure | v4 consequence | v6 consequence |
|---|---|---|
| permissive rule ordered above the deny | harmless, no forward exists | immediate exposure |
| ruleset silently only matches one address family | v4 covered, v6 ungoverned | whole segment on default |
| new VLAN added, firewall not updated | just a VLAN | live on the internet at first RA |
| ISP re-delegates a different prefix | n/a | address-literal rules stop matching |
**How to apply:**
- Key rules on **interface/zone, not address literals** — a re-delegated prefix
must not be able to silently unmatch a rule.
- Treat "enable v6 on a segment" as a change requiring the policy to exist
*first*, not as a networking toggle followed by cleanup.
- **Verify from outside.** Probe the segment's v6 addresses from off-net and
confirm the denies hold. This is §3's "assert the effective value, not the
presence of a substring" applied to firewall policy: a ruleset that *says*
deny is not evidence that packets are dropped.
Operator position on the ESH fleet (2026-08-19): **no 1:1 inbound pass-through.**
The policy work is writing and proving default-deny, not deciding what to expose.
---
## Superseded claims
| date | claim | correction |
|---|---|---|
| 2026-08-18 | "ESH behind CGNAT will break the inter-site tunnels, so IPv6 is the escape hatch" | **Half true, and the halves matter.** Tested live on RFC1918 double-NAT (`192.168.200.111`): **Site Magic (NH3↔ESH, WireGuard) HELD** — it dials out to NH3's public edge and never needs inbound reachability. **IPsec (colo↔ESH, ana-gw FortiGate) BROKE** — traceroute showed traffic unencapsulated, leaking to the carrier. IPv6 keeps its justification on the IPsec link only. |
| 2026-08-18 | *(my own, same day)* "no addressing outcome on the fiber threatens the inter-site tunnel" | **Over-generalised.** I proved it for WireGuard and wrote it as if it covered every link. Operator caught it. See lesson 8. |

> **Live as of 2026-06-27** on the PFI gateway (`ana-docker:4000`; canonical config

These are **overrideable defaults**: any caller that passes its own sampling param
wins; callers that omit one inherit the value below. (Verified — vLLM rejected an
out-of-range `presence_penalty=5.0`, proving per-request values reach the backend and
override the config default.) Values set per the `dvalin-smithy-dev` research pass
(provenance-cited in-thread, corroborated by §3 above). vLLM-only params (`top_k`,
`repetition_penalty`) ride in `extra_body` so LiteLLM's `drop_params` can't strip them.

**Notes:**
- **qwen "gen" family `presence_penalty: 1.0`** — operator-set anti-repetition for the
abliterated/NVFP4 Qwopus 122B-A10B. Qwen documents `presence_penalty` (0–2) as *the*
repetition lever; 1.0 is conservative (the §3 vendor general value is 1.5 — step up to
1.5 if loops persist). Do **not** use `repetition_penalty` for the Qwen3 family.
- **GLM (z.ai cloud) — only `temperature` + `top_p` are set.** z.ai's chat API schema
accepts no `top_k` / `min_p` / penalties, so they're deliberately not sent (would be
silently dropped). These temps match z.ai's own API defaults (explicit-over-implicit /
future-proofing).
- **Both `temp 0` values (granite, image-judge) are research-confirmed, not heuristic.**
Greedy is correct for constrained summ/classify (IBM) and for judge reproducibility
(Qwen judge card + LLM-as-judge practice). `temp 0.1` was explicitly evaluated and
rejected: it adds sampling noise without fixing loops, and *reduces* run-to-run score
consistency on the judge. If granite ever loops in production, fix via
`repetition_penalty` / `presence_penalty` / `max_tokens`, not a temperature floor.
- **`qwen-image-bench` / `image-judge` is arbo's hero-judge** (comfy-dev consumer) —
sampling changes there are a coordination item, not a unilateral gateway edit.

# Fleet reranker selection — process ledger
Running record of the Brokkr-driven fleet-reranker selection, and every
assumption / autonomous decision infra-ops makes on the operator's behalf
during it. The operator (Vuong) will review this at the end and reverse
anything he wants. **This is the audit trail for unattended operation.**
Started: 2026-08-06. Driver: **brokkr-smithy-dev**. Executor: **infra-ops** (this session).
---
## Operator authorization envelope (2026-08-06)
Brokkr drives a reranker-selection process; infra-ops is cleared to proceed on
Brokkr's recommendations **unattended** (no per-step operator check-in), with
authority to do whatever is necessary to reach a recommendation **or**
implementation.
**CLEARED (green):**
- Execute Brokkr's reranker-selection recommendations unattended.
- Bring **down the prod reranker** at `ana-ml2:8002` (qwen3-reranker-0.6B) —
**temporarily OR permanently**.
- Down **ONE** of the RP (roleplay) seats on ana-ml2 **temporarily** to free
GPU/VRAM for testing.
- Temporarily clear space for the smoke/bench.
- Pull models, stand up side-port vLLM benches, run the harness — whatever the
eval needs.
**RED LINES (hard NO — stop + surface even under standing auth):**
- **NO permanent deletion of anything** (no `rm`/`docker volume rm`/model-weight
deletion/data destruction). Downing ≠ deleting.
- **NO taking anything else offline** beyond (a) the prod reranker and (b) ONE
ana-ml2 RP seat. (Not granite/embed/reward/coder/gen/a second RP seat/muninn/etc.)
- **NO rebooting machines.**
**Process:** accumulate assumptions here; operator reverses at the end.
---
## Standing assumptions / autonomous-decision log
- **A1 — Coordinated-change notify still applies.** Even under unattended auth,
every `:8002` state change gets a timestamped announcement to worldtree-dev +
brokkr-smithy-dev (their standing coordinated-change ask; the operator waived
per-step *operator* approval, not the peer *notify* courtesy). No silent flip.
- **A2 — Weights are never deleted, only unserved.** "Permanently down the qwen
reranker" = stop serving + (optionally) repoint the gateway alias; the 0.6B
model weights stay on disk (deletion is a red line).
- **A3 — RP-seat pick = lowest-impact, temporary, restored after.** When a seat
must come down for VRAM, I pick the lowest-impact RP seat, log which + its
exact restore command, and bring it back when the bench frees the GPU.
---
## Current board at handoff
- **Prod reranker:** `ana-ml2:8002` = `vllm-rerank` (Qwen/Qwen3-Reranker-0.6B),
reverted to baseline `classifier_from_token:["no","yes"]`, healthy. Compose:
`/opt/docker/compose/vllm/compose.yaml` (canonical mirror
`stacks/vllm/compose.yaml`). Gateway alias `reranker`/`qwen3-reranker` →
litellm → :8002.
- **Root cause (converged, both sides):** 0.6B is capacity-bound on bare-name
queries over a real candidate pool; NOT misconfigured. Fix = larger model.
- **Verified on-prem candidate shortlist (all HF-real, ungated):**
Qwen/Qwen3-Reranker-4B, Qwen/Qwen3-Reranker-8B, mixedbread-ai/mxbai-rerank-large-v2,
mixedbread-ai/mxbai-rerank-base-v2, BAAI/bge-reranker-v2-gemma,
Alibaba-NLP/gte-reranker-modernbert-base, jinaai/jina-reranker-v2-base-multilingual.
(BAAI/bge-reranker-v2-m3 exists but the fleet already moved off it.)
- **Eval assets (all on nh3-dev):**
- Scorer: `scripts/probe_389_rank_decomposition.py` (Worldtree repo, main) —
rank-recovery = `rrf_rerank` column climbing back toward `rrf`.
- worldtree-dev grids: `~/snapshots/r42-gate-snapshot/` (probe_389_run3.json,
probe_389_question_shaped.json, probe_389_bigboi_control.json).
- Frozen gate Chroma snapshot: `~/snapshots/r42-gate-index/` (retained until
worldtree-dev signals the lever run is done).
- **Dual query-set requirement (hard):** score bare-name anchor queries AND
question-shaped; bar = recovering the name-lookup class.
- **VRAM:** 4B ≈ 4–5 GB fp8, 8B ≈ 9 GB; ana-ml2 Blackwell has headroom.

## Progress log
### 2026-08-06 — A2 brought up (Brokkr thread 01KZBSTSJA…)
- **Backend:** `vllm-rerank-a2` — standalone `docker run` (NOT in the vllm compose
stack), on ana-ml2 **GPU1**, host port **:8012** → container 8000. Image
`vllm/vllm-openai:latest` (=0.24.0). Args: model
`tomaarsen/Qwen3-Reranker-0.6B-seq-cls`, `--runner pooling`, `--gpu-memory-utilization
0.03`, `--max-model-len 8192`, `--dtype auto`, `--restart no`. Native
`Qwen3ForSequenceClassification` — NO hf-overrides. Routes /rerank /score /classify.
- **Gateway alias:** `reranker-a2-qwen3-seqcls` → `http://10.250.50.54:8012/v1`,
mode rerank. Added via LiteLLM **`/model/new`** (DB-backed, `store_model_in_db:true`)
— **no gateway restart** (respects the "nothing else offline" line). Verified 200
through the gateway.
- **Metrics:** VRAM ≈ **3.5 GB** (GPU1 free 14167→10616 MiB). Latency (20-doc pool,
~1500-char docs, shared GPU1): single p50 **87 ms**; 8-concurrent p50 **140 ms**,
~**55 req/s**.
- **Correctness (3-probe smoke, not the grid):** tracks the incumbent within noise →
early signal the failure is the **training prior, not the inference head**.
**Autonomous decisions this step (reversible):**
- D1 — port :8012, GPU1, util 0.03 to mirror the incumbent's exact footprint (clean control).
- D2 — standalone `docker run` (not compose) so bench arms are throwaway; no canonical churn to revert.
- D3 — gateway wired via `/model/new` (runtime, DB-persisted) rather than config-edit + restart.
- D4 — did NOT down any RP seat (A2 is 0.6B / 3.5 GB; no VRAM pressure).
**Cleanup for A2 (run at end / on reversal):**
- `ssh infra-ops@10.250.50.54 'sudo docker stop vllm-rerank-a2 && sudo docker rm vllm-rerank-a2'`
- Delete gateway alias: `POST /model/delete {"id": <model_id>}` (id via `/model/info?model_name=reranker-a2-qwen3-seqcls`), infra-ops admin key. (DB-persisted, so it survives a restart — must be explicitly deleted.)
- No weights deleted (red line); HF cache under /tank/aimodels/huggingface retains the 0.6B-seq-cls download.
**Ports reserved for the bench:** :8012 (A2), :8013 (A3), :8014 (A4), :8019 (A5).
### 2026-08-06 — A3 + A4 pre-staged (Brokkr said pre-stage in parallel, hold A5)
- **A3** `vllm-rerank-a3` — ana-ml2 GPU1 :8013, `BAAI/bge-reranker-v2-m3`
(XLMRobertaForSequenceClassification), same run pattern, util 0.03. VRAM ≈ **2.3 GB**.
Latency (20-doc, ~1500-char, shared GPU1): single p50 **105 ms**; 8-conc p50 214 ms, ~34 req/s.
Gateway alias `reranker-a3-bge-v2-m3` via /model/new (200, verified).
- **A4** `vllm-rerank-a4` — ana-ml2 GPU1 :8014, `Alibaba-NLP/gte-reranker-modernbert-base`
(ModernBertForSequenceClassification), util 0.02. VRAM ≈ **1.4 GB**. Latency: single
p50 **102 ms**; 8-conc p50 153 ms, ~51 req/s. Gateway alias `reranker-a4-gte-modernbert`
via /model/new (200, verified).
- **Smoke (2-doc, NOT authoritative):** BOTH decisively rank the bare-name Hobgoblin doc top
(A3 0.999, A4 0.982) where A2/incumbent FAIL (0.33). Cross-encoder / different-lineage.
Caveat: Brokkr warned isolated tests overstate; his 20-pool grid is the real call.
- **GPU1 state:** A2+A3+A4 ≈ 7.2 GB resident; GPU1 free ≈ **6.9 GB**. No RP seat downed.
If A5 (4B, ~4–5 GB) is greenlit: fits GPU1 tight or GPU0 (~9 GB free) — no RP-seat downing expected.
**Cleanup for A3/A4 (same pattern as A2):** `docker stop/rm vllm-rerank-a3 vllm-rerank-a4`
on ana-ml2; `/model/delete` the two aliases (DB-persisted); weights retained in HF cache.
### 2026-08-06 — A2 verdict (Brokkr full grid): training-prior confirmed
- **A2 ≡ incumbent, statistically indistinguishable** (identical gold-rank on 7/8 probes,
max 1-rank divergence; n=14: A2 7/14 top-10 @ mean rank 9.71 = incumbent to 2 dp;
no-reranker 13/14 @ mean 2.79). The seq-cls head changes nothing → the fault is a
**training prior in the weights**, not the scoring head. (Smoke called it pre-grid.)
- **A5 (Qwen3-Reranker-4B): HELD INDEFINITELY, not staged** per Brokkr — A2 voided its
rationale (scale can't fix a prior the head wasn't causing). *Decision: the one expensive
bring-up is avoided unless Brokkr formally revisits.*
- **A3/A4:** proceed — already live for Brokkr's grid; now a training-corpus test (BGE vs
GTE vs Qwen data), lower EV, cost sunk. Awaiting his scoring.
- **Likely endgame:** NO model swap. Recommendation trending to a **policy change** —
wing-scoped rerank bypass or `rrf:60` fusion — landing as Worldtree core code behind
config, NOT a new serving commitment. Would FREE a GPU seat, not allocate one; prod
`reranker` eventually retired for the fiction path (never silently repointed; Brokkr
flags before anything touches the prod alias). *Plan: if confirmed, tear the whole bench
down (A2/A3/A4 containers + 3 aliases) and hand back the GPU.*
### 2026-08-06 — FINAL verdict (Brokkr R43.1): A3 wins; cutover HELD for operator
- **Winner: A3 = `BAAI/bge-reranker-v2-m3`.** Write-up:
`research/R43-fleet-reranker-selection/RECOMMENDATION.md` (Brokkr repo, tag R43.1).
- **The incumbent harms the fleet, not just fiction.** n=90 over main + knowledge_base:
| arm | top-10 | mean rank | harmed vs no-rerank |
|---|:--:|:--:|:--:|
| A0 no-reranker | 89/90 | 0.54 | — |
| A1 incumbent | 56/90 | 7.78 | **80/90 (worst −19)** |
| **A3 bge-v2-m3** | 90/90 | 0.19 | 7/90 (worst −3) |
| A4 gte-modernbert | 90/90 | 0.08 | 1/90 (worst −1) |
- **A3 over A4:** A4 edges A3 on main/kb + is smaller/faster, BUT A4 is **English-only
(ModernBERT)** → silent degradation on non-English fleet content; A3 is **multilingual
(XLM-R)** and decisively better on the bare-name regime that started this. A3 also ~1.2 GB
*cheaper* than the incumbent. A4 kept as documented throughput fallback.
- **CUTOVER = OPERATOR DECISION (pending).** Brokkr drafted then PULLED the repoint: a
fleet-wide alias change affecting consumers he doesn't own shouldn't ship on a relayed
blanket auth while the operator is away. → Surfaced to Vuong. Proceeding-on-Brokkr's-rec
now literally = HOLD. **Nothing torn down (incl. A2); prod `reranker` :8002 stays incumbent.**
- **Cutover conditions (when operator says yes):** repoint gateway `reranker` alias
incumbent→A3; keep incumbent :8002 warm (rollback = one alias edit); keep
`reranker-a3-bge-v2-m3` as its own distinct alias; keep A4 up as fallback; **announce the
boundary timestamp on-bus** (worldtree probe re-run + Brokkr v13 gate render need it).
- **Flag (worldtree-side, not infra):** `rerank_hybrid_floor` should be **dropped, not
re-tuned** — it compensates for the scorer being replaced. No serving work to stage for it.
### 2026-08-06 — CUTOVER SHIPPED (operator authorized directly + to Brokkr)
- **Operator authorized** the fleet repoint (to me: "go a/3"; to Brokkr directly: "go ahead
with the cutover") and explicitly cleared the litellm restart blip ("authorized to blip litellm").
- **BOUNDARY: 2026-08-06T17:37:48Z.** Gateway `reranker` alias now resolves 100% to A3
(`BAAI/bge-reranker-v2-m3` @ :8013). Verified through gateway: "Hobgoblin Pus" relevant
doc top @ 0.9989 (BGE signature; incumbent was ~0.33).
- **Mechanism:** `reranker` was config-defined (not DB), config mounted `:ro`, no hot-reload →
edited `/opt/docker/conf/litellm/config.yaml` reranker block (block-scoped script, asserted
1+1 change) + `docker restart litellm`. **Blip was ~52s** (litellm reloads all 28 models on
boot), not the ~15s estimated — reported honestly to operator + Brokkr + worldtree-dev.
- **`qwen3-reranker` alias LEFT UNTOUCHED** → incumbent still served at :8002 (rollback path;
also avoids a false alias — the Qwen name still names the Qwen model).
- **Canonical synced:** `stacks/litellm/conf/config.yaml` reranker block updated to match live.
(Live config had pre-existing drift from canonical — only the reranker block was reconciled.)
**ROLLBACK (one-liner, ~1 min):** revert the `reranker` block in
`/opt/docker/conf/litellm/config.yaml` to `model: hosted_vllm/Qwen/Qwen3-Reranker-0.6B` +
`api_base: …:8002/v1` (backup at `config.yaml.bak-pre-rerank-cutover-*`), then
`sudo docker restart litellm`. Incumbent backend (`vllm-rerank` :8002) is up and untouched.
### OPEN / cleanup owed at process end (operator reverses/approves)
- **A5** never staged (Brokkr cancelled) — nothing to clean.
- **A2 (`vllm-rerank-a2` :8012)** + alias `reranker-a2-qwen3-seqcls` — bench-only, tear down when
Brokkr signals the bake-off is closed (`docker stop/rm` + `/model/delete`).
- **A4 (`vllm-rerank-a4` :8014)** + alias — KEEP for now (Brokkr's documented throughput fallback).
- **A3 (`vllm-rerank-a3` :8013)** — now PRODUCTION (backs the `reranker` alias). Hardened
2026-08-06: `docker update --restart unless-stopped` (survives ana-ml2 reboot, no recreate).
A4 given the same. **Remaining follow-up (not urgent): promote A3 from throwaway `docker run`
to a canonical compose service** (`stacks/vllm/`) for config-managed consistency — a recreate,
so do it in a window since it briefly drops `reranker`.
- **Incumbent (`vllm-rerank` :8002)** — keep up as rollback until Brokkr/worldtree close the
post-cutover watch; retire (not delete) only on explicit sign-off.
- **`rerank_hybrid_floor`** — Brokkr routing to worldtree-dev directly (drop, don't re-tune).
### 2026-08-06 — VERIFIED + A2 torn down + throughput characterized
- **Brokkr independent verify: CUTOVER VERIFIED** — prod `reranker` == `reranker-a3-bge-v2-m3`
at maxdiff 0.000000 (5 samples, spread 0.000009), single backend, no split routing.
- **R42 v13 acceptance gate PASSES** — anchors_flip 4/4, no_regression 8/8, no_distractor_rise
TRUE, zero aborts. **First PASS in R42 history after 4 failed verdicts.** Production main+kb:
56/90 → 90/90 top-10; evictions 33 → 0.
- **A2 torn down** (Brokkr signalled done): gateway alias `reranker-a2-qwen3-seqcls` deleted
(/model/delete 200) + container removed. ~3.5 GB freed on GPU1. Remaining: `vllm-rerank`
(incumbent, rollback), `vllm-rerank-a3` (prod), `vllm-rerank-a4` (fallback).
- **Throughput characterized (the one open risk):** A3 caps ~34 req/s — flat from 8→16
concurrent while latency climbs gracefully (p50 214→332→456 ms; p99 525 ms @16-conc). It
QUEUES, doesn't cliff. ~40% below the incumbent's ~55 req/s. Likely fine for fleet rerank
QPS (internal, per-search), but if real p99/queue-depth bites: levers are (a) swap to A4
(~51 req/s, but English-only), (b) raise A3 `--gpu-memory-utilization` for bigger batching
(recreate = brief blip), (c) run a 2nd A3 replica load-balanced behind `reranker` (~2× tput,
identical replicas so no split-measurement issue now the bake-off is closed). Brokkr will
re-run the grid against A4 if it bites — no intuition swaps.

# Training throughput playbook — how to find where the step time went
_Sibling to [`model-quantization-playbook.md`](model-quantization-playbook.md).
That one is for making a model small; this one is for making a training run
fast. Same contract: **model-agnostic lessons live here, model-specific ones
stay in the per-model artifact and link up.**_
First written 2026-08-24 out of the Gemma-4 26B-A4B ERP/RP tune, which ran at
8.6% MFU and cost a four-model frontier panel and most of a night to explain.
The worked example in §7 is that run. The lessons above it are not about
Gemma-4.
> **Read this before hypothesising about kernels.** The single most expensive

> arithmetic instead of spending ten minutes on a measurement that settled
> it.* Two of the panel's conclusions were retracted by their own authors
> within the hour. Every retraction was a derivation; every survivor was a

## 1. The 10-minute triage — do this FIRST, always
Before you profile, before you read a modelling file, before you ask anyone:
**measure the step's scaling curve.** Three sequence lengths, fixed batch,
fwd+bwd, best-of-2 after a warmup.
t(w) = A·w + B·w² w = per-sequence length
Fit two parameters to three points. The residuals tell you which regime you
are in, and the regime tells you which lever exists:
| observed `t(4w)/t(w)` | regime | the lever |
|---|---|---|
| ~4× | **linear** — per-token work dominates | fewer tokens; fused elementwise |
| ~16× | **quadratic** — attention dominates | attention backend / kernel |
| ~1× | **launch-bound** — fixed per-batch cost | CUDA graphs, `torch.compile`, bigger batch |
**If the two-term fit closes with residuals under ~1%, launch-bound is
refuted.** You did not need a constant term, so there is not a meaningful one.
This is the cheapest possible refutation of the most seductive wrong answer,
and it costs one extra data point.
### ⚠ 1.1 ⭐⭐ Three points minimum. A two-point fit with three plausible terms is UNDETERMINED
This is the lesson that cost the most. A two-point fit over {quadratic,
linear, fixed} has infinitely many solutions, and which one you land on is
decided by whichever per-step number you happened to quote. In the worked
example a peer produced **two confident, opposite conclusions from the same
method inside an hour** — "attention is ~5 s of 35" and then "attention is
21–33 s of 35" — because the inputs drifted between attempts.
Three points, two parameters, and check the residuals. If they do not close,
you have a third term and you need a fourth point.
### ⚠ 1.2 ⭐⭐ Benchmark the shape you RUN, not the worst case you can construct
The quadratic share is **strongly shape-dependent** — in the worked example it
ran 20.9% at w=2,048, 51.3% at w=8,192, 67.8% at w=16,384. A synthetic
`max_seq_len` benchmark therefore measures the shape where attention looks
worst, and generalising from it overstates the attention prize by ~1.3×.
Get the real distribution off the encode cache and weight by it:
E[t] = A·E[w] + B·E[w²]
**`E[w²]` is not `E[w]²`.** For a bimodal length distribution they can differ
by 2× or more, and a quadratic term is dominated by the rare long batches that
an `E[w]²` shortcut averages away. In the worked example `E[n²]/E[n]²` was
**2.08**.
Sanity check the weighted prediction against the observed `s/it` before you
trust any of it.
---
## 2. The reference probe set
Committed at [`scripts/training-probes/`](../../scripts/training-probes/).
Run them in this order; each is minutes and none needs the real checkpoint
except the profiler.
| probe | what it settles | needs GPU? |
|---|---|---|
| `step0_mask.py` | mask band structure + which layers keep the fast path | no |
| `step2_padding.py` | padding waste, length distribution, CE chunk sizing | no |
| `step_bucket.py` | bucketing gain, bucket-size sweep, root diversity | no |
| `step1_profile.py` | scaling fit, padding penalty, CE wall clock, kernel table | yes |
`step1_profile.py` loads the real model but reuses the harness's own
`discover_target_modules` and `compute_loss`, so it measures the thing that
actually runs rather than a re-implementation. **Keep that property when you
adapt it** — a probe that reimplements the training step measures the probe.
---
## 3. The recurring landmines
### 3.1 ⭐⭐ Right-padding is a compute tax AND a backend tax
Everyone knows padding wastes tokens. The second effect is the one that gets
missed: **an explicit padding mask can knock fast-path-eligible layers off
`is_causal`.**
`scaled_dot_product_attention` takes `is_causal=True` **or** an `attn_mask`,
never both usefully. HF sets `is_causal=True` only when `attention_mask is
None`. Right-pad a batch and you hand it a 2D mask, it materialises a 4D
tensor, and every layer that could have taken the clean causal route now takes
a masked dense one.
Measured, same width, same `n`, only the mask differing:
no padding 35.244 s 26,048 loss targets
50% pad on one row 38.567 s 19,640 loss targets
**9.4% slower for 24% less work.** Verify this on your own stack with
`step0_mask.py` — it prints whether `create_causal_mask` returns `None` or a
tensor for each mask case.
### 3.2 ⭐⭐ Length-bucket to PAIR, shuffle micro-batches to MIX — and the bucket should be TIGHT
Naive length-bucketing has a real hazard: length correlates with data source,
so length-homogeneous batches are **source-homogeneous batches**, and an
accumulation window can end up drawing its entire gradient from one root.
The fix costs nothing: **form micro-batches within length buckets, then
shuffle the resulting micro-batches globally.** Padding efficiency is a
property of the pairing alone, so all of the saving survives the shuffle.
**The non-obvious part — bucket size is not a diversity knob.** Measured
across a 256× range of bucket sizes, roots per accumulation window stayed flat
at 3.54–3.61 (against 3.68 for a pure shuffle). The *global micro-batch
shuffle* does all of the mixing; the bucket contributes nothing to diversity
and only costs padding. So use the tightest bucket you can — which in the
limit is a full length sort.
| bucket | padding waste | zero-pad micro-batches | roots/window |
|---|---|---|---|
| current (shuffle) | 29.9% | 0.1% | 3.68 |
| 2 | 0.0% | **78.3%** | 3.56 |
| 32 | 0.1% | 41.9% | 3.55 |
| 512 | 2.4% | 4.1% | 3.61 |
Note the `zero-pad micro-batches` column — that is §3.1 compounding. A tight
bucket does not merely cut tokens, it puts most batches back on the causal
fast path.
**Peak memory does not rise.** `padded = batch × max(len)`, so one long record
forces a full-width batch regardless of its partner. Bucketing pairs long
records *with each other*, which roughly halves the number of worst-case
batches.
### 3.3 ⭐⭐ Check the kernel GENERATION, not just the backend name
The backend name (`EFFICIENT_ATTENTION`, `FLASH_ATTENTION`, …) is not the whole
story. Read the actual kernel symbols out of the profiler:
fmha_cutlassF_bf16_aligned_32x128_gmem_sm80
fmha_cutlassB_bf16_aligned_128x64_k65536_sm80
^^^^
`sm80` is **Ampere**. Those were running on an sm_120 Blackwell card, on the
dominant cost centre of the step. A backend can be "selected correctly" and
still be a generation behind, and nothing in the config surface tells you.
Also read the variant suffix: `gmem` on the forward kernel is the
**global-memory fallback tier** of the memory-efficient path, chosen when the
working set will not fit in shared memory. Wrong backend *and* that backend's
slow path.
### 3.4 ⭐ `key_averages()` double-counts — use device-kernel rows only
`torch.profiler`'s `key_averages()` table lists both the ATen op and the CUDA
kernel it launched, each carrying the same `self_device_time_total`. Summing
the whole table gives you roughly **2× the real step time**.
The tell is exact equality between an `aten::` row and a kernel row:
aten::_efficient_attention_backward 30 16144.6
fmha_cutlassB_bf16_aligned_128x64_k65536 30 16144.6
Filter to device kernels (`void …`, `fmha_…`, `cutlass::…`, `Memcpy…`) and
sanity-check the total against the measured wall clock. In the worked example
the filtered total came to 89.5% of the step, which is the right shape; the
unfiltered total came to 202%.
### 3.5 ⭐ Time the loss forward AND account for its backward recompute separately
If the loss head is gradient-checkpointed, a CUDA-event window around the
forward loop measures **half the story at best** — the recompute happens inside
`.backward()`, outside your window.
State the caveat explicitly when you report the number. In the worked example
the CE forward measured 374 ms of a 35.3 s step (1.1%); even at 3× for
recompute-plus-backward it is ~3%, which was enough to kill a proposed
dependency swap — but "1.1%" alone would have been an unearned claim.
### 3.6 ⭐⭐ Assert mask band structure directly; never infer it from performance
`transformers` can **silently skip mask creation** and pass
`attention_mask=None` when a mask function is not registered. If that fires on
a sliding-window model, the windowed layers do full causal attention — not a
speed bug, **a different model from the one you will serve**.
There is a tempting alibi: "if constraints were dropped we would be on the
fast path and fast; we are slow, therefore correct." It is decent evidence and
it is not an assertion. Materialise the mask once and count allowed positions
per row:
sliding_attention max 1,024 allowed/row, saturates at row 1,023 PASS
Thirty seconds, on CPU, no weights. Do it before every run that changes the
masking path, and before believing any optimisation result.
### 3.7 ⭐ "Bit-identical output from a different backend" — ask *could this have disagreed?*
A backend flag that produces `max_abs_diff == 0.0` against the reference is
either (a) legitimately the same GEMMs behind a different launcher, or (b) a
flag that never took. **Argument cannot separate these** — in the worked
example three frontier models split 2–1 on it and the majority was not
obviously right.
Do not resolve it by vote. **Count kernel launches.** A per-expert loop leaves
`n_experts` dispatches per layer visible; a grouped path leaves one. That is
unambiguous and falls out of a trace you are running anyway.
Related trap: **a trace of the default path does not test the flag.** If the
run was relaunched without the flag set, the profile tells you what the default
does and nothing about the flag. Say so rather than over-claiming.
### 3.8 ⭐ MFU is a denominator argument waiting to happen — report the decomposition instead
MFU invites an unwinnable fight about what counts as a FLOP (active vs dense
params for MoE, whether checkpoint recompute counts, whether frozen-base
skipped GEMMs count). That fight consumed an hour of the worked example and
produced nothing.
Report these **beside** MFU, not instead of it:
- tokens/s, and **real (unpadded) tokens/s** separately
- achieved hardware FLOPs straight from the profiler
- the time decomposition (attention / GEMM / elementwise / other)
Then the denominator stops mattering.
**The reading that actually diagnosed it** was not an MFU number at all:
> 100% SM utilisation at 279–292 W, running 27 TFLOPS, on a card that does
> 304 TFLOPS on a dense GEMM at the same power.
**SM-busy, tensor-core-idle.** The chip is fully occupied doing work that is
not matrix multiplication. No FLOP-counting convention changes that, and it
points straight at the kernel table.
### 3.9 Frozen-base LoRA is ~4ND, not ~6ND — and the arithmetic intensity does NOT drop
A claim that circulated and was wrong: "frozen-base LoRA has structurally lower
arithmetic intensity, so a dense-GEMM ceiling is unreachable in principle."
The correct accounting: forward is 2ND, input-gradient backward through the
frozen weights is 2ND, and only the weight-gradient (~2ND) is skipped. So
**~4ND against ~6ND — two-thirds of the work, at the same arithmetic intensity
per remaining GEMM.** You do fewer GEMMs; the ones you do are exactly as dense.
Gradient checkpointing is a separate, real ~⅓ recompute tax. Account for it
separately rather than folding it into an intensity story.
---
## 4. Panel / consult discipline for perf work
Perf investigations are unusually good at generating confident wrong answers,
because the arithmetic is easy and the ground truth is expensive. Specific
guards, learned the hard way:
- **Every arm's claim gets a measurement or an expiry date.** In the worked
example the panel produced four self-retractions in ninety minutes. The
measurements produced zero.
- **Treat cross-arm agreement as weak evidence.** Ask arms to attack a
hypothesis rather than extend it; agreement among similarly-primed readers of
the same artifact is not independent confirmation.
- **A dispute about what a specific dispatcher does is a question of fact.**
Do not put it to a panel. Instrument it.
- **When an arm says "you missed X," check what they read.** If your settled
artifact was not on their reading list, the "miss" is usually
restatement-of-a-settled-prior, not a genuine gap.
---
## 5. Superseded claims — do not follow these
| claim | status | replaced by |
|---|---|---|
| "Explicit mask → `EFFICIENT_ATTENTION`" is over-specific; Blackwell defaults to `CUDNN_ATTENTION` | **WRONG** (2026-08-24) | Measured: sm_120 selects `fmha_cutlass*_sm80`, i.e. `EFFICIENT_ATTENTION`. The original claim was right. |
| Attention's quadratic share is ~5 s of a 35 s step | **WRONG** (2026-08-24) | Measured 22.8 s / 65.2% at w=16,384; 67.8% by independent scaling fit |
| Frozen-base LoRA has structurally lower arithmetic intensity | **WRONG** (2026-08-24) | ~4ND vs 6ND at unchanged intensity — see §3.9 |
| The chunked CE is a 2–5× under-estimated cost centre | **WRONG** (2026-08-24) | Measured 1.1% of step forward, ≲3% with recompute |
| `attn_implementation="flash_attention_2"` is the per-layer lever | **NOT A FLAG** (2026-08-24) | All-or-nothing at `from_pretrained`; per-layer needs a custom fn on `ALL_ATTENTION_FUNCTIONS`. FA2 also caps head_dim at 256. |
| Bucket size ~256 is needed to preserve source diversity | **UNNECESSARY** (2026-08-24) | Diversity is flat in bucket size; the global micro-batch shuffle does that work — see §3.2 |
## 6. Measured negatives — don't re-chase
- **Fused MoE kernel (`grouped_mm`) as the throughput fix.** Measured 0.9%
*slower* than the Python loop and bit-identical. Independently, dense GEMM is
only 7.9% of the step, so the whole category is capped near 10%.
- **CUDA graphs / `torch.compile` over the expert loop.** The two-term scaling
fit closed without a constant term, so there is no meaningful fixed per-batch
cost to amortise. ~3,840 expert-GEMM launches per forward are not what you
are paying for.
- **`liger-kernel` fused linear CE.** Real and correct, but a ~1–3% lever on
this shape. Not a project.
- **FlashAttention-4 on sm_120.** Public reports are sour — one measurement of
1.07× over FA2, and an sm_120 patch people could not get working that fell
back to torch SDPA. Do not bet a round on it.

## 7. Worked example — Gemma-4 26B-A4B ERP/RP tune, 2026-08-24
Model-specific detail lives in
[`gemma4-erp-tune-sizing.md`](gemma4-erp-tune-sizing.md) §6. The short version,
because the *shape* of the investigation is the transferable part:
**Symptom.** 8.6% MFU, ~35–46 s/it, 1,312 steps, ~13.9 h ETA.
**What the panel produced.** Four frontier arms plus an orchestrator, over
ninety minutes: a sliding-window hypothesis, a retraction of it, a retraction
of the retraction, a correctness scare that resolved itself, two mutually
contradictory readings of one dispatcher, and four self-corrections.
**What settled it, in about twenty minutes of GPU time:**
scaling fit (3 points, 2 params, residuals <3 ms over an 8× range)
A = 6.87e-4 s/token B = 8.85e-8 s/token²
quadratic share: 20.9% @ w=2,048 → 67.8% @ w=16,384
kernel table (device rows only)
attention 22,835.8 ms 65.2% fmha_cutlass*_sm80
dense GEMM 2,774.0 ms 7.9%
other 5,739.0 ms 16.4%
Two independent methods, 2.6 points apart. **Attention was the answer, on
Ampere-generation kernels, with the forward on a global-memory fallback tier.**
**The largest actionable win was not the attention kernel.** It was a sampler
change — bucket-to-pair, shuffle-to-mix — worth 29.9% of tokens and ~35.5% of
wall clock, with no new dependency, no kernel work, and unchanged peak memory.
It also wins under *every* branch of the diagnosis, which is why it was
recommended while the rest was still unresolved.
**The transferable ordering:**
1. Assert correctness (mask band structure). Everything downstream assumes it.
2. Scaling curve. Names the regime in ten minutes.
3. Kernel table. Names the cost centre.
4. Data-side levers first (padding, bucketing) — they need no dependency and
they multiply into every other cost.
5. Kernel/backend levers last, gated on 2 and 3.

## TL;DR — coverage matrix
Two independent layers. **PBS = whole-VM images. restic = granular
file+DB.** A host is well-covered if it has *either* a current PBS image
*or* a current restic snapshot; the danger zone is a host whose **only**
layer has failed.
| Host | Kind | PBS (VM image) | restic (file+DB) | Sole net? |
|---|---|---|---|---|
| ana-docker | VM (pfi-pve) | ✅ `ana-pve` | ✅ → rest-server-**ana** | no |
| **ana-ml2** | **bare metal** | ❌ none (not a VM) | ✅ → rest-server-**ana** | ⚠️ **restic is the ONLY net** |
| **irv-ml1** | **bare metal** | ❌ none (not a VM) | ✅ → rest-server-**nh3** | ⚠️ **restic is the ONLY net** |
| nh3-docker | VM (nh3-pve) | ✅ `nh3-pve` | ✅ → rest-server-**nh3** | no |
| esh-docker-vm | VM (esh-pve) | ✅ `esh-pve` | ✅ → rest-server-**ana** | no |
| esh-vm-db | VM (esh-pve-nas) | ❌ **none** (esh-pve-nas not a PBS source) | ✅ → rest-server-**ana** | ⚠️ **restic-only (a DB!)** |
| vm-esh-nas | VM (esh-pve-nas) | ❌ **none** (esh-pve-nas not a PBS source) | ✅ → rest-server-**ana** | ⚠️ **restic-only** |
| other pfi-pve / nh3-pve VMs/CTs | VM/CT | ✅ respective ns | (PBS only) | no |
| SureFire `sfsrv-pve` | tenant VMs | ✅ `sfsrv-pve` ns | (PBS only) | no |
**Bare-metal hosts have NO PBS coverage** (PBS only backs up Proxmox
guests). Their restic snapshot is the entire safety net — keep an eye on
it. ana-ml2 → rest-server-ana; irv-ml1 → rest-server-nh3.
---
## Layer 1 — PBS (whole-VM/CT images)
- **PBS-ANA** (`pbs-ana`, 10.250.50.90) — fleet primary. Datastore is
NFS-backed: `10.250.50.50:/mnt/backup/pbs-ana` mounted at
`/mnt/pbs-datastore` (~20 TB). Backs up Proxmox guests via vzdump,
organised by **namespace per source hypervisor**:
- `ana-pve` — pfi-pve guests (ana-docker, pfi-postgres VM105, ana-nas
CT109, webhost, filebot, pteradactyl, tacticalrmm, ana-wg, …)
- `esh-pve` — esh-pve guests
- `nh3-pve` — nh3-pve guests
- `sfsrv-pve` — SureFire tenant
- ⚠️ there is **no `esh-pve-nas` namespace** — guests on that
hypervisor (vm-esh-nas, likely esh-vm-db) are **not** PBS-covered.
- **PBS-NH3** (`pbs-nh3`, 10.100.50.90) — DR mirror; syncs from PBS-ANA
(datastore on nh3-nas).
- Schedule: vzdump jobs defined in Proxmox (Datacenter → Backup),
staggered through the early morning.
## Layer 2 — restic (granular file + DB)
restic clients push to one of **two rest-server endpoints** (HTTP, basic
auth, append-only, private repos). The split is by site:
| rest-server | Endpoint | Backing store | Clients |
|---|---|---|---|
| **rest-server-ana** | `http://10.250.50.70:8000` (container `rest-server` on ana-docker) | `ana-nas:/mnt/backup/restic/repo/ana` (NFS bind → `/data`) | ana-docker, **ana-ml2**, esh-docker-vm, esh-vm-db, vm-esh-nas |
| **rest-server-nh3** | `http://10.100.50.50:8000` (on nh3-nas) | `nh3-nas:/volume1/Backup/restic/<client>` | **irv-ml1**, nh3-docker |
- Per-client repos live as subdirs of the rest-server data dir
(`.../repo/ana/<client>/` for the ana side); the shared `.htpasswd`
for ana sits at `.../repo/ana/.htpasswd`.
- **Scheduler = `resticprofile` systemd timers on each client host**, NOT
Backrest:
- `resticprofile-backup@profile-default.timer` — daily **01:00** PDT
- `resticprofile-check@profile-default.timer` — weekly (Sun **05:00**)
- **Backrest** (container on ana-docker, UI) is only a **repo viewer here
— it has 0 plans.** Do not assume "Backrest healthy" means "backups
running." The timers are the source of truth.
- ⚠️ **Failures are silent** — a timer fires, restic errors against a
down endpoint, and nothing alerts. (See Known gaps.)
---
## The 2-minute freshness check
Run these any time you need to answer "are we backed up?"
```bash
# --- restic ANA side: newest snapshot per client (want: today/yesterday) ---
ssh ana-nas 'for c in ana-docker ana-ml2 esh-docker-vm esh-vm-db vm-esh-nas; do
echo -n "$c: "; ls -t /mnt/backup/restic/repo/ana/$c/snapshots/ 2>/dev/null | head -1 \
| xargs -I{} stat -c "%y" /mnt/backup/restic/repo/ana/$c/snapshots/{} 2>/dev/null || echo MISSING
done'
# --- restic NH3 side ---
ssh nh3-nas 'for c in irv-ml1 nh3-docker; do
echo -n "$c: "; ls -lt /volume1/Backup/restic/$c/snapshots/ 2>/dev/null | sed -n 2p
done'
# --- rest-server endpoints healthy? (401 = up & serving; Restarting = broken) ---
ssh infra-ops@ana-docker 'sudo docker ps --format "{{.Names}}\t{{.Status}}" | grep rest-server'
curl -s -o /dev/null -w 'rest-server-ana: %{http_code}\n' http://10.250.50.70:8000/
curl -s -o /dev/null -w 'rest-server-nh3: %{http_code}\n' http://10.100.50.50:8000/
# --- PBS: newest snapshot per guest, all namespaces ---
ssh pbs-ana 'for ns in /mnt/pbs-datastore/ns/*/; do nsn=$(basename "$ns")
for d in vm ct; do for g in "$ns$d"/*/; do [ -d "$g" ] || continue
echo "$nsn/$d/$(basename "$g") -> $(ls "$g" 2>/dev/null | grep ^20 | sort | tail -1)"
done; done; done'
```
**Force a backup now (don't wait for 01:00):** on the client host,
`ssh infra-ops@<host> 'sudo systemctl start resticprofile-backup@profile-default.service'`
(it's an incremental against the existing repo — bounded even if stale).
---
## Known failure mode: rest-server-ana crash-loop (the 2026-05-06 → 2026-06-20 outage)
**Symptom:** `rest-server` container on ana-docker stuck `Restarting`;
logs show `cannot load /data/.htpasswd: permission denied`. All ana-side
restic backups silently fail.
**Root cause:** ana-nas's NFS mount on ana-docker uses bare `defaults` in
`/etc/fstab` (no `_netdev`, no retry). When the mount drops,
`mnt-backup.mount` gets stuck `failed`, so `/mnt/backup/restic/repo/ana`
resolves to an **empty local ghost dir** (no `.htpasswd`) and rest-server
binds *that*. ana-nas itself is fine — the real repos are intact.
**Recovery** (needs root on ana-docker — use **`ssh infra-ops@ana-docker`**,
which has NOPASSWD sudo; the default `ssh ana-docker` lands as `lkraven`
*without* sudo):
```bash
ssh infra-ops@ana-docker '
sudo mount -a # re-attach the NFS (bypasses the failed unit)
sudo systemctl reset-failed mnt-backup.mount # clear the stuck unit state
mount | grep /mnt/backup # confirm nfs4 attached
sudo ls /mnt/backup/restic/repo/ana/.htpasswd # real htpasswd now present
cd /opt/docker/compose/rest-server-ana && sudo docker compose up -d --force-recreate
' # recreate so the bind re-resolves onto NFS
# verify: docker ps shows Up (healthy); curl :8000 -> 401; logs say "Loaded htpasswd file"
```
If the ghost dir blocks the mount, see `disaster-recovery.md` Tier-0 for
the stop→umount→rm-ghost→remount→start variant.

## Known gaps / TODO
- [x] **Backup-freshness alerting — DONE (2026-06-20).**
`scripts/check-backup-freshness.sh` (the 2-min check, exit 1 on
stale/down) + a daily **systemd user timer on nh3-dev** at 08:00
(`scripts/install-backup-freshness-timer.sh`) → `backup-freshness-alert.sh`
posts an **althing alert to infra-ops** on any stale/down layer. Run the

you want a louder one.)
- [x] **fstab hardening — DONE (2026-06-20).** ana-docker `/mnt/backup` →
`noauto,x-systemd.automount,x-systemd.mount-timeout=30` (autofs self-heals
on a NAS blip instead of getting stuck `failed`; activates on next reboot).
`/etc/fstab.bak-pre-harden` saved. **`/mnt/compose` also hardened the same
way** and **activated live** (umount → `mnt-compose.automount` started →
autofs verified remounting on access) — it binds no container, so it was
safe to convert now; this also proved the autofs pattern works on ana-docker.
- [ ] **ana-ml2 has no PBS net** (bare metal) — restic is its only layer; now
healthy + alerted. Bulk `/tank` models are re-downloadable; bespoke
quants/configs/scripts are the real loss-risk.
- [x] **esh-pve-nas coverage — VERIFIED (2026-06-20): NOT PBS-covered.** No
`esh-pve-nas` namespace exists on PBS-ANA, so **esh-vm-db (postgres+mongo)
+ vm-esh-nas are restic-only.** For the DB VM, restic-with-dumps is the
*preferred* method (vs a VM image) **IF** the resticprofile includes
`pg_dump`/`mongodump` — confirm that. Optionally add esh-pve-nas as a PBS
source. ESH is home-lab (no SLA).
- [ ] **Rotate rest-server repo passwords** — the 5 per-repo basic-auth creds
were exposed during the 2026-06-20 diagnosis. **BELAYED** — operator

# esh-pve-nas — moving PVE root off the USB DOM
**Status: DONE — cut over 2026-08-18.** Root is `nvme/ROOT/pve-1` on the mirrored
NVMe; `/boot` is ext4 on the DOM; the DOM is out of the runtime I/O path. All five
guests healthy, all three pools ONLINE, `systemctl is-system-running` = `running`.
The ext4 root (`pve-root`) is intact, unmounted, and still carries its own kernel
and initrd as the rollback.
Post-cutover boot config: `saved_entry=pve-zfs-root`, no `next_entry`. If grubenv
were ever unreadable GRUB falls through to menu entry 0, which the
`/etc/default/grub.d/zfs-root.cfg` drop-in also points at `root=ZFS=nvme/ROOT/pve-1`
— so every path boots ZFS.
⚠ **The window cost an unplanned outage, caused by a bug in this runbook's own
tooling, not by the migration.** Read § The mount-propagation incident before
running anything like this again. Two other findings — the blast radius being
more than double what was documented, and the one-shot rollback not actually
working — are recorded in § The pool-name bug's neighbours below.
Staging is two playbooks, both rerunnable:
| phase | playbook | what it did |
|---|---|---|
| 1 | `playbooks/esh-pve-nas-stage-zfs-root.yaml` | carved the `/boot` LV out of swap, populated it, rsynced the root into `nvme/ROOT/pve-1`, wrote the copy's fstab |
| 2 | `playbooks/esh-pve-nas-stage-bootloader.yaml` | ZFS initramfs, grub.cfg, rollback entry, grubenv — **without** `grub-install` |
**Plan revised 2026-08-17** from "reinstall to a mirrored-NVMe ZFS root" to
**"split the boot chain from the root filesystem"** — operator's proposal, and it
is strictly better. The original reinstall plan is kept at the bottom as the
fallback.
## Why
PVE root lives on a **USB Disk-on-Module** — `sdq`, 7.3 GB, `ID_BUS=usb`,
`ID_VENDOR=NORELSYS` — as a 6 GB ext4 root plus 768 MB swap and a 512 MB ESP.
A DOM is SLC/pSLC with a real controller, so the 284 GB written since boot is
unremarkable and **wear is not the driver**. The actual problems:
1. **It is on the USB bus.** A bus reset or re-enumeration drops the *root
filesystem* out from under a running hypervisor while its guests keep going.
2. **6 GB has no headroom** — `/usr` alone is 3.7 GB.
3. **Unmirrored**, while 928 GB of mirrored NVMe sits 96% empty.
4. **It has blocked patching for months.** This is the operator-visible symptom
and the real urgency: `apt-get -s dist-upgrade` shows **225 packages pending,
161 of them carrying `deb12uN` / Debian-Security bumps** — including `ssh
1:9.2p1-2+deb12u10`. The host sits on `pve-manager/8.4.11` while its sibling
esh-pve is on 8.4.14, and it has 20 weeks of uptime because it cannot take a
kernel.
⚠ **Do not attempt the upgrade before the migration.** The pending set
includes `proxmox-kernel-6.8.12-42-pve-signed` (from -13) — a signed kernel
plus initramfs is ~250 MB, and **`/boot` is on root**, which has 1.3 GB free.
225 packages unpacking (dpkg, perl, glibc-adjacent) into that headroom risks
filling the disk mid-transaction and leaving a broken dpkg state on a
hypervisor running five guests. Recovering a wedged dpkg on a full root is
far worse than waiting for the reboot.
If patching genuinely cannot wait, the escape hatch is to keep downloads off
root — `apt-get -o Dir::Cache::Archives=/nvme/tmp/apt-archives dist-upgrade`
— but the kernel still lands in `/boot` on root, so this reduces the risk
rather than removing it. Migrating first is the shorter path to safety.
## The design: boot on the DOM, root on ZFS
Boot and root do not have to live on the same device. Split them:
| | device | contents | written when |
|---|---|---|---|
| **boot** | DOM `sdq` | ESP + `/boot` (ext4): GRUB, kernels, initramfs | **only on kernel/GRUB updates** |
| **root** | `nvme` pool | `nvme/ROOT/pve-1` — everything else | constantly, on mirrored NVMe |
GRUB reads the kernel and initrd from **ext4 on the DOM**, so GRUB never has to
read ZFS — which matters, because the `nvme` pool has `encryption`,
`large_dnode` and `zstd_compress` enabled and GRUB cannot read those. The
initramfs then imports the pool and pivots to `root=ZFS=nvme/ROOT/pve-1`.
### Why this beats the reinstall
- **The `nvme` pool is not destroyed.** The root dataset is created *inside* the
existing pool. No guest migration, no `zpool export/import` of `ssd`/`tank`,
no reinstall.
- **Downtime is one reboot**, not half a day.
- **Rollback is a GRUB menu entry.** The existing ext4 root stays on the DOM,
untouched. If ZFS root fails to come up, pick the old entry and you are back in
a minute. That is a far better rollback than "reinstall and restore."
- **The #1 risk is actually retired.** Once booted, root is on NVMe — a USB bus
reset mid-run no longer takes the running system down. The DOM becomes
read-mostly.
- **Free upside: boot environments.** `zfs snapshot nvme/ROOT/pve-1@pre-upgrade`
before an apt run, roll back if it breaks.
### What it does NOT fix
The DOM remains the **only boot path**. If it dies, the machine will not boot
until the image is restored — though the ZFS root, with all config and guests,
stays intact. Mitigation is a **cloned fallback image** (`dd` of `sdq`, ~7 GB,
refreshed after kernel updates), kept off-box next to the config snapshot.
## Preconditions — all already satisfied
Verified on the host 2026-08-17:
- **UEFI** firmware, `grub-efi-amd64 2.06-13+pmx7` installed
- **`zfs-initramfs 2.2.8-pve1` is already installed**, and the running initrd
already carries **76 ZFS files** — the pivot capability exists today, no new
packages. (The pending upgrade would take ZFS to 2.2.10-pve1; 2.2.8 is fully
capable of root-on-ZFS, so migrate on what is installed and upgrade after.)
- `/boot` is currently *part of* root (108 MB), so it must be split out onto its
own ext4 filesystem on the DOM as part of this work
- root is only **4.3 GB** to copy
- swap is 767 MB with 123 MB used against 125 GB of RAM — irrelevant; leave it
on the DOM LV. **Do not put swap on a zvol** (deadlock risk)
⚠ **`cachefile` is `none` and `/etc/zfs/zpool.cache` is 0 bytes** — pools import
by scan today (verified: `zfs-import-scan.service` active,
`zfs-import-cache.service` inactive). For root-on-ZFS this must be
deterministic, or the pool may not be imported early enough to find root.
⚠⚠ **Set the cachefile on ALL THREE pools, not just `nvme`.** An earlier draft
of this runbook said `zpool set cachefile=/etc/zfs/zpool.cache nvme`, and that
one-pool form is a trap. Populating a cachefile flips the host from
import-by-scan to import-by-cache — so a cache containing only `nvme` means
**`ssd` and `tank` never get imported at boot.** CT 103 `esh-nas` has twelve
bind mounts spanning all three pools (`/tank/media`, `/ssd/compose`,
`/nvme/nvme-pvestore`, …), so the NAS would come up with every export empty and
both NFS clients would hang on `hard` mounts. The scoped-looking command is more
dangerous than the broad one.
Done 2026-08-18 for `nvme`, `ssd` and `tank`; verified all three present in the
resulting 11,976-byte cache via `zdb -C -U /etc/zfs/zpool.cache`. Phase 1's
third guard step re-asserts this on every run.
## ⚠ Blast radius — unchanged, and still the gating constraint
**CT 103 `esh-nas` (10.0.50.50) is the NAS, and it runs on this host.** Two
dependents mount it over **`hard`** NFS — they do not fail, they hang unkillably:
| client | mounts |
|---|---|
| **esh-docker-vm** (10.0.50.45) | `/mnt/books`, `/mnt/backup` |
| **esh-pve** (10.0.250.35) | `/mnt/pve/esh-nas`, `/mnt/pve/tank-vmbu` |
This is a known incident shape: the only remedy for esh-docker-vm's D-state is a
host reboot, and `/mnt/books` was *deliberately* left `hard` because calibre's
SQLite risks corruption under `soft`.
The reboot in this plan is brief, but it is still a reboot — quiesce the clients
first.
## Where the `/boot` LV came from — the VG was full
The original step 7 said `/boot` could "stay inside the DOM's existing LVM as
its own small ext4 LV, or reuse the freed space once root moves off." Neither
was available: **VG `pve` had 4 MB free**, and the 6 GB root is mounted ext4,
which cannot shrink online — freeing space from it needs a rescue boot, which
would have cost the "one reboot" property the whole design rests on.
The only space reclaimable live was the **768 MB swap LV** (123 MB in use
against 125 GB of RAM). Operator's call 2026-08-17: **shrink swap rather than
drop it.** Final layout:
| LV | size | role |
|---|---|---|
| `pve-root` | 6.04 G | ext4 — **untouched**, the rollback root |
| `pve-boot` | 512 M | ext4 — the new `/boot` (NEW) |
| `pve-swap` | 256 M | swap (was 768 M) |
Rejected alternatives: dropping swap outright (more kernel headroom, no OOM
cushion); `proxmox-boot-tool` on the 512 MB ESP (PVE-native and no LVM surgery,
but it reformats the ESP and downgrades rollback from "pick a menu entry" to
"restore the DOM image"); rescue-boot to shrink root (keeps swap whole, costs a
second reboot and an offline resize of the filesystem we are fleeing).
## Sequence
**Pre-flight (no downtime)** — done 2026-08-18
1. `dd` the DOM to an off-box image. **Crash-consistent, not clean** — the root
LV is live during the read, so a restore replays the ext4 journal. That is
fine for its purpose (boot-chain insurance) and is what a snapshot backup
does anyway. Not fixable with an LVM snapshot: the VG has no free extents.
2. Refresh the config snapshot (`nh3-dev:~/backups/esh-pve-nas/`).
3. `zpool set cachefile=/etc/zfs/zpool.cache` on **`nvme`, `ssd` AND `tank`**
(see the precondition warning above — the one-pool form breaks the NAS).
**Phase 1 — `playbooks/esh-pve-nas-stage-zfs-root.yaml`** (live, no disruption)
4. `zfs create -o mountpoint=none nvme/ROOT`, then `nvme/ROOT/pve-1` with
`canmount=noauto`, `compression=zstd`, `xattr=sa`, `acltype=posixacl`.
Create it with `mountpoint=none` and only set `/` at the very end —
`canmount=noauto` alone is the documented guard, but never having a dataset
that claims `/` while the ext4 root is live is the guard that cannot misfire.
5. Reclaim the swap LV into `pve-boot`, mkfs, populate from `/boot`.
6. Mount the dataset at `/mnt/newroot` and rsync the live root in.
`--one-file-system` does the exclusion work: every path the old plan listed
by hand (`/proc /sys /dev /run /nvme /ssd /tank /var/log/journal /boot`) is
already a separate mount, so it is skipped structurally rather than by a
list that can drift.
7. Write the copy's `/etc/fstab`: no root line (the initramfs mounts it), plus
`/dev/pve/boot /boot ext4`, the ESP, and swap.
**Phase 2 — `playbooks/esh-pve-nas-stage-bootloader.yaml`** (live, no disruption)
8. Chroot into the copy with the boot LV and ESP mounted, then
`update-initramfs -u -k all` + `update-grub`.
9. ⚠⚠ **`grub-mkconfig` gets the ZFS root WRONG here, silently. Override it.**
See § The pool-name bug below — this is the single most dangerous thing
found during staging.
10. `GRUB_DEFAULT=saved`, plus `40_custom` carrying **both** boot paths as
hand-authored entries with stable ids (`pve-zfs-root`, `pve-ext4-rollback`),
with grubenv pinned to the **rollback**, not to ZFS (see § Cutover for why).
## ⚠ The pool-name bug — the near-miss worth reading
Left to itself, `update-grub` on this host produces:
```
linux /vmlinuz-6.8.12-13-pve root=ZFS=/ROOT/pve-1 ro quiet intel_iommu=on
```
**The pool name is missing.** It should be `root=ZFS=nvme/ROOT/pve-1`. That
boots to an initramfs prompt — with CT 103 `esh-nas` down and both NFS clients
hanging on `hard` mounts, at whatever hour the window happens to be.
It is not a typo, and it is not random. Debian's `/etc/grub.d/10_linux` builds
the ZFS root as `${rpool}${bootfs}`:
| part | from | value here |
|---|---|---|
| `rpool` | `grub-probe --device <dev> --target=fs_label` | **empty** |
| `bootfs` | `make_system_path_relative_to_its_root /` | `/ROOT/pve-1` |
`grub-probe --target=fs /` fails outright on this pool — `grub-probe: error:
unknown filesystem` — because **GRUB's own ZFS reader cannot open a pool with
`encryption`, `large_dnode` and `zstd_compress` enabled.** So `rpool` comes back
empty and concatenates to nothing.
That is the *same* feature set that forced `/boot` to stay ext4 on the DOM. The
design already accounted for GRUB being unable to read the pool; what was missed
is that the same limitation also corrupts the kernel command line — and does it
**without an error**, because `grub-probe`'s failure is swallowed by
`2>/dev/null || true`.
**The fix, in two layers:**
1. `/etc/default/grub.d/zfs-root.cfg` sets
`GRUB_CMDLINE_LINUX="root=ZFS=nvme/ROOT/pve-1 boot=zfs"`. This is appended
*after* the bogus value, and both the kernel and the zfs initramfs script
take the **last** `root=` on the line — so every auto-generated entry becomes
correct. A drop-in, not an edit to `/etc/default/grub`, so a grub package
upgrade cannot revert it in a conffile merge.
2. `40_custom` carries an explicit `pve-zfs-root` entry with a single clean
`root=` and a stable id. That is what cutover's `grub-reboot` targets — the
auto-generated ids are derived from pool member device paths
(`gnulinux-simple-/dev/nvme0n1p1_/dev/nvme1n1p1`) and would shift if the
mirror ever changed.
**The general lesson, which is the transferable part:** the phase-2 verify step
originally grepped for `root=ZFS=nvme/ROOT/pve-1` *appearing somewhere* in
grub.cfg. Once the drop-in was added that grep passes — while pool-less entries
sit in the menu untouched. The check that actually holds walks every `linux`
line, takes the **last** `root=` on it, and asserts it against a known-good set.
Assert the effective value, not the presence of a substring.
10. **`grub-install` is deliberately NOT run during staging.** The ESP stub
still points at the old `/boot` inside the ext4 root, so the host's boot
path stays byte-identical to what it has been for 140 days. Everything
error-prone is built and verified in advance; the ESP rewrite is a
two-second idempotent command held back to the window.
**Cutover** — the remaining work, § Cutover below.

> to the quantization playbook. Everything below is the ESH-specific narrative;
> the rules that would bite on any host are collected there.
## ⚠ The mount-propagation incident — the expensive lesson of 2026-08-18
**What broke.** The staging chroot was built with `mount --rbind /dev` and `/sys`
and **no `--make-rslave`**. On a systemd host `/` has *shared* propagation, so
those binds propagate in both directions. When the cutover tore the chroot down
with `umount -R`, the unmounts **propagated back into the live host** and removed
the real `/sys/fs/cgroup`, `/dev/pts` and `/dev/shm`.
With cgroup2 gone, `systemd-logind` could no longer create a session. The result
is a host that:
- answers ping, accepts TCP, and **completes SSH authentication**
- keeps serving from daemons already resident in memory (`pveproxy` returned a
clean HTTP 401 throughout)
- **hangs on every new `exec`**, including `/sbin/reboot` — so the reboot that was
supposed to end the window never ran
**Why it cost so much time: it is a near-perfect impostor of failing root-disk
I/O.** Both present as "host is up, daemons answer, nothing new can start." The
session diagnosed it as the USB DOM dying and told the operator to walk to the
machine. That was wrong, and the operator caught it: the DOM had been reliable
for years and the wedge began immediately after a change.
**The evidence that settles it, and was available the whole time** — from
`dmesg`, obtainable in the brief windows when exec did succeed:
| line | says |
|---|---|
| `[16.00] sd 56:0:0:0: [sdq] Attached SCSI removable disk` | DOM enumerated **cleanly, no errors** |
| `[12114881.98] systemd[1]: nvme-varlog-stage.mount: Deactivated` | timestamp is **140 days** — this is the ORIGINAL boot |
That second line is the whole answer: **the machine never rebooted.** A
down-detector loop had also never once reported the host down; that was read as a
fast reboot rather than as no reboot at all.
**Rules that follow:**
1. **Always `mount --make-rslave` after `mount --rbind` into a chroot.** Phase 2
now does this and carries a guard that refuses to continue if any bind still
reports `shared` propagation.
2. **A reboot is not confirmed until the host is observed DOWN.** Poll for
disappearance, not just for reappearance. "Never went down" and "went down and
came back fast" are indistinguishable if you only watch for the host to answer.
3. **Before blaming hardware for a wedge that began right after a change, get
`dmesg` and check the boot timestamp.** Diagnose the change first; hardware is
the explanation of last resort, not first.
**Recovery took no console access.** Windows where `exec` briefly succeeded were
enough to land an idempotent remount of cgroup2 / devpts / shm, after which
`systemctl reset-failed` returned the host to `running`. Total data loss: none.
The root filesystem, the DOM and all three pools were never at risk — this was a
mount-namespace fault, not a storage one.
## The pool-name bug's neighbours — two more corrections
**The blast radius was more than double what was documented.** The runbook named
two NFS dependents. `ss -tn '( sport = :2049 )'` inside CT 103 showed **five**:
| client | mount | disposition |
|---|---|---|
| `10.0.50.45` esh-docker-vm | `/mnt/books`, `/mnt/backup` — **hard** | quiesced |
| `10.0.250.35` esh-pve | `esh-nas`, `tank-vmbu` — **hard** | quiesced |
| `10.0.50.60` **esh-vm-db** | `/mnt/backup` — **hard** | **left mounted deliberately** |
| `10.0.50.154` vm-esh-nas | — | is VM 104 *on this host*; stops with it |
| `10.100.10.50` nh3-dev | `/mnt/books` — **soft,ro** | safe, errors instead of blocking |
Ask the *server* who its clients are. A runbook's list of dependents is a snapshot
that rots; `ss` on the NFS server is ground truth.
esh-vm-db was left mounted on purpose and **came through read-write** — a `hard`
mount with no active user blocks and resumes, which is what `hard` is for. Its
backup timers were ~19h out, and unmounting would have meant an unmount/remount
cycle over the qemu guest agent on a host with no ssh access.
**The one-shot rollback does not work, and the warning was right.**
`grub-reboot` printed *"Detected GRUB environment block on lvm device — will
remain the default boot entry until manually cleared."* Confirmed empirically:
after the successful ZFS boot, `next_entry=pve-zfs-root` was **still set**. GRUB
can read grubenv on LVM but cannot write it, so `boot_once` degrades to a sticky
default. **There is no auto-fallback on this host.** A failed boot must be
corrected at the console.
The steady-state config therefore does not rely on it: `saved_entry=pve-zfs-root`
with `next_entry` cleared. Restoring a real one-shot would mean relocating grubenv
onto the ESP (vfat on a plain partition, which GRUB *can* write) — parked, not
required.
## Cutover
The only remaining work. Everything below the quiesce is minutes.
1. **Quiesce the NFS clients** (see § Blast radius). On **esh-docker-vm**
(10.0.50.45) stop whatever holds `/mnt/books` and `/mnt/backup` and unmount
them; on **esh-pve** (10.0.250.35) disable the `esh-nas` and `tank-vmbu`
storages. Do this first and confirm it — a `hard` mount left live turns a
brief reboot into an unkillable D-state needing a reboot of *that* host too.
2. Shut down the five guests.
3. Point the ESP at the new `/boot` and arm the one-shot:
```
chroot /mnt/newroot grub-install --target=x86_64-efi \
--efi-directory=/boot/efi --bootloader-id=proxmox
chroot /mnt/newroot grub-reboot '<zfs entry id — phase 2's verify prints it>'
```
4. Set the dataset's final mountpoint, then reboot:
```
zfs set mountpoint=/ nvme/ROOT/pve-1 # canmount stays noauto
reboot
```
**Why `grub-reboot` and not a new default.** `GRUB_DEFAULT=saved` with grubenv
pinned to the ext4 rollback means the ZFS entry is tried **exactly once**. If it
fails, the next reboot returns to ext4 *by itself* — no console, no hands. That
matters more here than on a normal host: a boot that hangs at an initramfs
prompt takes CT 103 `esh-nas` down with it, and the NFS clients hang rather than
fail. Only after the second successful ZFS boot (§ Verification) should the
saved default move to the ZFS entry with `grub-set-default`.
## Verification
- `findmnt -no SOURCE,FSTYPE /` → `nvme/ROOT/pve-1 zfs`
- `df -h /` shows hundreds of GB, not 5.9
- `findmnt /boot` → ext4 on the DOM; `/boot/efi` mounted
- all five guests running; CT 103 serving NFS (`pct exec 103 -- exportfs -v`)
- esh-docker-vm remounted and healthy; esh-pve storages green
- **a second reboot** to prove it was not a one-off
- only then: refresh the DOM image, since `/boot` has changed
## Rollback
Instant and cheap at every stage: the ext4 root on the DOM is never modified, and
its GRUB entry stays in the menu. Worst case is a boot to initramfs → reboot →
pick the old entry. Keep the ext4 root for at least a few weeks of normal
operation before reclaiming it.
## Open decisions
- **Second boot device?** The split fixes runtime fragility but not boot-time
single-point-of-failure. A cloned DOM/USB as a cold spare is the cheap answer.
- **`esh-filebot` (CT 106)** is an empty container — 80 GB quota, six passthrough
mounts, nothing running since March. Retire rather than carry it.
- **Reclaiming the old ext4 root** once the ZFS root has proven itself.
---
## Fallback plan: full reinstall to a mirrored-NVMe ZFS root
Only if the split above proves unworkable. Fresh PVE install to ZFS RAID1 across
both NVMes — mirrored boot with proper ESPs under `proxmox-boot-tool`, no USB in
the path at all.
Costs: the `nvme` pool must be destroyed, so its **32 GB of guest rootfs** moves
to `ssd` (1.42 T free) first; `ssd` and `tank` must be cleanly exported so the
installer cannot touch them; guest configs restore from the snapshot plus the 8
PBS backups per guest. Half a day, and rollback after the install step is
"reinstall and restore".
Note both NVMes are *whole-disk* ZFS members (partition 1 spans all 931.5 GiB,
1.7 MiB free), so adding an ESP to them without destroying the pool is
impossible — which is what forces the reinstall in this variant, and what the
split plan avoids entirely.

right at once — (1) quant as the *multimodal* class, (2) use the *modelopt* format not
compressed-tensors, (3) work around a vLLM bug that quantizes the MTP draft head.
---
## What / where
- **Model:** NEO-CODE = `DavidAU/Qwen3.6-27B-Heretic2-Uncensored-Finetune-Thinking` (dense
27B, `Qwen3_5` GDN-hybrid arch, multimodal `Qwen3_5ForConditionalGeneration`).
- **Runs only on ana-ml2 GPU0** (NVFP4 is Blackwell-only; irv-ml1 is Ampere).
- **Artifacts** (ana-ml2 `/tank/aimodels/heretic2-nvfp4-work/`, root-owned):
- `heretic2-mtp-bf16/` — BF16 graft (Heretic2 + 15 base-Qwen3.6 MTP tensors). [graft input]
- `heretic2-modelopt-nvfp4/` — modelopt NVFP4 quant, single shard, **no mtp**. [quant output]
- `heretic2-modelopt-nvfp4-mtp/` — the above + spliced 15 BF16 mtp → **the seat**. [SERVE THIS]
- (superseded: `heretic2-nvfp4-cg*` = compressed-tensors path, coherent but MTP-inert;
`heretic2-mtp-nvfp4-prod` = original gibberish. Keep for diff, do not serve.)
- **Scripts** (eshpfi `services/heretic2-nvfp4-quant/`): `graft_mtp.py`, `quant_modelopt.py`,
`finalize_modelopt_mtp.py`, `serve_modelopt_mtp.sh`, `sitecustomize-mtp-workaround.py`.
- **Reference:** the MoE `gen` (`qwen36-35b-a3b-heretic-nvfp4`, `quant_method: modelopt`) and
the qwopus-122B `gen` both ran MTP before (qwopus +12% single-stream, archival-memory
2026-07-01) — dropped for `gen` because MTP *hurts concurrency*, which is why it belongs on
the single-stream RP seats, not `gen`.
## GPU window ritual
Base NVFP4 quant needs ~55 GB free on GPU0. `docker stop llama-charrp
llama-charrp-reasoning vllm-aeon-gen` (→ ~97 GB free); restore with `docker start …`
(~90–230 s to healthy). The GGUF NEO-CODE seat is the always-restorable fallback. Heads-up
wt-dev (their character / thoughtful-character / gen route through these) — unless told
otherwise. `ssh ana-ml2` = lkraven, in the docker group (no sudo needed for docker).
---
## The pipeline (4 steps)
### 1. GRAFT (CPU, seats up) — `graft_mtp.py`
Heretic2's finetune dropped the MTP head; graft the 15 BF16 `mtp.*` tensors from base
`Qwen/Qwen3.6-27B` (shards 13+15). Symlinks Heretic2 shards + one `model-mtp.safetensors`.
Idempotent, refuses to clobber. Output: `heretic2-mtp-bf16/`.
### 2. QUANT (GPU0 window, ~18 min) — `quant_modelopt.py` via `run_quant_modelopt.sh`
`nvidia-modelopt` PTQ → **modelopt** NVFP4 format. Three things this script gets right (each a
gotcha — see below): loads as **`AutoModelForImageTextToText`**, patches the modelopt↔transformers
**FusedMoE** bug, and forces **single-shard** export. Excludes `lm_head` + `visual` + all
`linear_attn` (GDN) → BF16, matching AEON. Calib = the 512-row workload-matched chat mix.
```bash
docker run -d --name vllm-heretic2-modelopt-quant --gpus '"device=0"' --ipc host \
-v /tank/aimodels:/tank/aimodels -v /home/lkraven:/lk \
--entrypoint bash vllm/vllm-openai:v0.24.0 -c '
set -e
pip install -q nvidia-modelopt tiktoken sentencepiece 2>&1 | tail -1
python3 /lk/quant_modelopt.py \
--model /tank/aimodels/heretic2-nvfp4-work/heretic2-mtp-bf16 \
--calib-mode chat --calib /tank/aimodels/heretic2-nvfp4-work/production_calib_512.jsonl \
--num-samples 512 --seqlen 8192 \
--out /tank/aimodels/heretic2-nvfp4-work/heretic2-modelopt-nvfp4'
```
CPU dry-run (no GPU, tiny calib) to validate the pipeline without an outage: same command
minus `--gpus`, add `-e CUDA_VISIBLE_DEVICES=""`, `--num-samples 2 --seqlen 512`.
### 3. SPLICE (CPU) — `finalize_modelopt_mtp.py`
Copy `heretic2-modelopt-nvfp4` → `heretic2-modelopt-nvfp4-mtp`, splice the 15 BF16 `mtp.*`
tensors into the single shard (→ 1967 tensors). (The transformers load never builds an mtp
module, so mtp must be spliced post-quant — same as AEON/pantheon.)
### 4. SERVE (GPU0) — `serve_modelopt_mtp.sh` + the MTP workaround
```bash
docker run -d --name vllm-charrp-modelopt --gpus '"device=0"' --ipc host \
-v /tank/aimodels:/tank/aimodels \
-v <sitecustomize dir>:/lk_debug -e PYTHONPATH=/lk_debug \ # ← the MTP workaround, see below
-p 8018:8000 vllm/vllm-openai:v0.24.0 \
/tank/aimodels/heretic2-nvfp4-work/heretic2-modelopt-nvfp4-mtp \
--quantization modelopt \
--speculative-config '{"method":"qwen3_5_mtp","num_speculative_tokens":3}' \
--language-model-only --mamba-cache-dtype float32 \
--reasoning-parser qwen3 --tool-call-parser qwen3_coder --enable-auto-tool-choice \
--served-model-name char-rp-reasoning --max-model-len 40960 --max-num-seqs 32 \
--gpu-memory-utilization 0.5 --trust-remote-code
```
`--language-model-only` skips the vision tower (RP seat doesn't need it; saves ~1–2 GB — the
tower is preserved BF16 in the weights, so multimodal is recoverable by dropping the flag).
---
## The four landmines (each cost hours)
1. **Load as `AutoModelForImageTextToText`, NEVER `AutoModelForCausalLM`.** The latter resolves
`qwen3_5` → text-only `Qwen3_5ForCausalLM` → flat `model.layers.*` keys. vLLM only serves
`Qwen3_5ForConditionalGeneration`, whose weight mapper needs `model.language_model.*` (+
`model.visual.*`). Wrong class → every layer weight silently fails to load → **`!!!!` gibberish**.
2. **Use the MODELOPT format (nvidia-modelopt), not compressed-tensors (llm-compressor).** On
compressed-tensors the MTP drafter can't load the BF16 mtp head at all (`not found in
params_dict`, **0% acceptance** — loads but never accelerates; this is what pantheon and the
"AEON RP seat" actually were). Base NVFP4 *alone* ≈ GGUF at batch-1 (no single-stream win) —
**the MTP multiplier is the entire point**, and it needs modelopt.
3. **modelopt 0.45 ↔ transformers 5.12.1 FusedMoE crash.** `mtq.quantize` dies with
`TypeError: issubclass() arg 2 must be a class` — modelopt registered transformers' `FusedMoE`
(a *function* in 5.x) as an nn class. `quant_modelopt.py` guards it (patches
`_DMRegistryCls._get_registered_nn_class` to skip non-class registry entries). Do **not**
pin `nvidia-modelopt[hf]==0.43` to dodge it — that drags transformers back to 4.57 which can't
load `qwen3_5` at all.
4. **⭐ THE BIG ONE — vLLM 0.24.0 does not propagate modelopt `exclude_modules` to the
spec-decode DRAFT model.** The MTP drafter builds its own `qkv_proj`/`gate_up_proj` as
*quantized* (NVFP4-packed) while the mtp head is BF16 → `AssertionError: param_data.shape ==
loaded_weight.shape` in `qwen3_5_mtp.py:256`. **No checkpoint config fixes this** — instrumenting
`is_layer_skipped` proved the drafter's exclude list contains only the *main* model's
`linear_attn` entries, never the mtp ones. Also note `is_layer_skipped` does **exact string
membership, not glob** — so wildcards like `mtp.layers.0.*` never match anything. **Fix = a
runtime patch** (`sitecustomize-mtp-workaround.py`, mounted on `PYTHONPATH`) that force-skips
any `mtp.*` prefix in `is_layer_skipped`, keeping the drafter BF16. This is a genuine vLLM bug —
**report upstream** (draft-model quant-config should inherit the target's exclude_modules).
## Verify it's actually accelerating
```bash
# coherence
curl -s :8018/v1/completions -d '{"model":"char-rp-reasoning","prompt":"The old tavern","max_tokens":40,"temperature":0}'
# drive tokens, then read acceptance from the seat log:
docker logs vllm-charrp-modelopt 2>&1 | grep SpecDecoding | tail -2
# -> "Mean acceptance length: 2.19 ... Avg Draft acceptance rate: 39.7%" [GOOD: >0%, ~2 length]
# -> "Avg Draft acceptance rate: 0.0%" [BAD: compressed-tensors, or mtp quantized]
```
`SpecDecoding` line only appears during active generation. 0% acceptance = you're on
compressed-tensors, or the workaround didn't load (check for `[ISLS] ... workaround installed`).
## Productionization TODO (not yet done)
- Bake the sitecustomize workaround into a compose stack (mount + `PYTHONPATH`), served-name
`char-rp-reasoning`, alongside/replacing the GGUF seat.
- brokkr P00 (soong 9-tool k5) — same base model as GGUF NEO-CODE so R36 should carry, but the
NVFP4-vs-Q5 quality + tool-path must be confirmed before cutover.
- Repoint gateway `char-rp-reasoning` alias + heads-up wt-dev.
- File the vLLM upstream bug (draft-model exclude non-inheritance).

# nh3-dev `~/development` — hourly off-box backup
**Why this exists:** nh3-dev is the dev box where agents do uncommitted work under
`~/development/<project>/`. That tree had **no off-box backup**, so a destructive
mistake (a stray `rm -rf` on a working dir on 2026-07-12) had no safety net. This
job closes that gap: an hourly, versioned, off-box snapshot of `~/development`.
## What it does
- **Source:** `nh3-dev:~/development/` (lkraven's working dirs).
- **Destination (off-box):** `nh3-nas:/volume1/Backup/nh3-dev-development/<YYYY-MM-DD_HHMM>/`
— a timestamped dir per snapshot, over rsync-**over-ssh** (syncuser).
- **Versioning:** `rsync --link-dest` against the previous snapshot → unchanged
files hardlink (share inodes, ~0 bytes); only changed files consume new space.
`latest` symlink points at the newest snapshot.
- **Retention:** newest **48** hourly snapshots (older pruned each run).
- **Excludes:** heavy reconstructable dirs (`node_modules`, `.venv`, `venv`,
`__pycache__`, `.pytest_cache`, `.mypy_cache`, `.ruff_cache`, `.cache`, `dist`,
`build`, `.next`, `target`, `*.pyc`) and secrets (`.env`, `.env.*`, `*.pem`,
`*.key`, `id_*`, `*.sqlite*`). **`.git` is kept** (local commits/stashes = the
uncommitted work that matters). Seed snapshot ≈ **11G**; hourly deltas are MB-scale.
## Where it lives (on nh3-dev)
- Script: `~/.config/dev-backup/dev-backup.sh` (mirror committed at
`scripts/nh3-dev-development-backup.sh`).
- systemd `--user` units: `~/.config/systemd/user/dev-backup.{service,timer}`
(`OnCalendar=hourly`, `Persistent=true`, linger on → fires without a login).
- Log: `~/.config/dev-backup/dev-backup.log`.
```bash
systemctl --user list-timers dev-backup.timer # next run
systemctl --user start dev-backup.service # run now
tail -f ~/.config/dev-backup/dev-backup.log
```
## Restore
Snapshots are plain dir trees — no special tool needed:
```bash
# list snapshots
ssh nh3-nas 'ls -1 /volume1/Backup/nh3-dev-development/'
# restore one file/dir from a chosen snapshot
rsync -a nh3-nas:/volume1/Backup/nh3-dev-development/<STAMP>/<proj>/<path> /tmp/restore/
# or pull a whole project back
rsync -a nh3-nas:/volume1/Backup/nh3-dev-development/latest/<proj>/ ~/development/<proj>/
```
## Notes / future
- **Not encrypted at rest** (plaintext on the trusted internal NAS; secrets are
excluded). Upgrade path: migrate to restic once a repo can be created on
rest-server-nh3 (currently returns 404 on repo-create — likely append-only) or
the Synology sftp subsystem is enabled (currently disabled → restic sftp fails).
- Off-box = off the nh3-dev VM (lands on nh3-nas, same NH3 site). Cross-site
mirroring of this repo is a separate future layer.

# soong-lab push-to-deploy (gitea webhook → corviduo-dev, test-gated)
Green-gated CI/CD for the soong-lab studio: **push to `main` → run the test
suite → redeploy the studio ONLY if tests pass** (running studio is never
touched on a red run). Built 2026-07-13 (Vuong-directed). Adapts the
[ytvc-autodeploy](./ytvc-autodeploy.md) webhook pattern.
## Flow
```
push→main → gitea webhook (POST, HMAC) → soong-webhook listener :9010 on corviduo-dev
→ ~/soong-lab-deploy.sh:
git clone (read-only deploy key, internal SSH :222)
uv sync ; uv run pytest ── RED → abort, studio UNTOUCHED, status=red
rsync backend/ → studio dir + web/ → SOONG_LAB_WEB_DIR ; uv sync --no-dev ; restart
→ status=green, studio healthy
```
## Components (all on corviduo-dev, user `infra-ops`)
- `~/soong-lab-deploy.sh` — clone → test → deploy-on-green. Logs to
`~/soong-lab-deploy.log`; writes `~/.config/soong/last-deploy.json`
(`{result: green|red, stage, sha, at}`).
- `~/soong-webhook.py` — HTTP listener on `:9010`. HMAC-SHA256 (`X-Gitea-Signature`)
vs `~/.config/soong/webhook-secret` (mode 600); fires the deploy only on
`ref == refs/heads/main`. `GET /` returns `ok | last: <status>`.
- `soong-webhook.service` (system unit, enabled) — runs the listener.
- Read-only deploy key `~/.ssh/soong-deploy_ed25519` → gitea repo key id 5 on
`vh/soong-lab` (read_only). Clone via `ssh://git@10.250.50.70:222/vh/soong-lab.git`.
- Studio unit `soong-lab-studio.service` (WD `/home/infra-ops/soong-lab/backend`);
restart needs infra-ops NOPASSWD sudo (present).
- Gitea webhook: repo `vh/soong-lab` hook id 3 → `http://10.250.50.152:9010/`,
JSON, Push events, the shared secret.
## Verify / operate
```bash
ssh corviduo-dev 'systemctl is-active soong-webhook.service; curl -s localhost:9010/'
ssh corviduo-dev 'tail -30 ~/soong-lab-deploy.log' # deploy history
# manual deploy (same as the webhook does):
ssh corviduo-dev 'bash ~/soong-lab-deploy.sh'
```
## Notes / gotchas
- **Frontend (`web/`) sync IS part of the deploy**: the studio serves `web/` from
`SOONG_LAB_WEB_DIR` (`/home/infra-ops/soong-lab/web`), *separate* from the backend
`WorkingDirectory`. The deploy rsyncs BOTH `backend/`→studio and `web/`→`SOONG_LAB_WEB_DIR`.
(Added 2026-07-13 after soong-dev caught the served frontend silently rotting — the backend
was updating while `web/` stayed pinned to the initial manual copy; a bounce alone re-serves
the same stale file.)
- **Green-gated by construction**: `pytest || fail` runs BEFORE any studio touch,
so a red suite aborts with the studio still on the old version. Validated
2026-07-13 (a mid-deploy rsync failure left the studio untouched/active).
- **rsync is required** on corviduo-dev (`apt install rsync` — installed 2026-07-13;
it wasn't present initially).
- **bifrost dep** resolves from the internal Gitea PyPI via `~/.netrc` (already
present on corviduo-dev); no extra auth in the deploy script.
- **⚠️ Auto-deploy silently never worked until 2026-07-14 — TWO compounding blockers.**
The LISTENER binds `0.0.0.0:9010` and works, but nothing gitea sent ever reached
it, so every push was a no-op (v0.3.6 was manual; v0.3.7–v0.3.15 never
auto-deployed until fixed). Two separate, both-real blockers:
1. **corviduo-dev ufw** — `default-deny`, only 22 + 8080 allowed, so a *direct*
TCP to :9010 from ana-docker DROP-timed-out. Fix: `ufw allow from 10.0.0.0/8`
(operator-directed — "that footgun happens a lot", accept the fleet).
2. **★ gitea `webhook.ALLOWED_HOST_LIST` (the DECISIVE one)** — was
`external, 10.100.0.0/16` (NH3 only); corviduo-dev is `10.250.50.152`
(Anaheim), so gitea **refused to deliver**: `webhook can only call allowed HTTP
servers ... deny '10.250.50.152'` — it never even opens the TCP connection, so
the ufw fix alone did nothing. Fix: `ALLOWED_HOST_LIST = external, 10.0.0.0/8`
in gitea `app.ini` (`/data/gitea/conf/app.ini`, `[webhook]`) + `docker restart
gitea` (~8s blip). The HMAC secret was already correct (once delivery arrives,
`hmac_ok=True`).
**RED HERRINGS that cost two diagnosis rounds:** (a) "test-delivery 204" is gitea
*queuing*, NOT delivering — never proves the round-trip; (b) a proxy test signing
with the *listener's own* secret (bypassing gitea) proves the listener but NOT
gitea's real delivery. **Diagnose from BOTH ends:** the SENDER (`docker logs gitea
--since 5m | grep webhook` → the `deny '<ip>'` line) AND an instrumented RECEIVER
— the listener now ships with delivery logging (`journalctl -u soong-webhook.service
| grep '\[webhook\]'` shows source-IP / hmac_ok / ref / action; the old
`log_message=pass` silence hid all of it). **Proof of fix:** a real gitea delivery
logs `POST from 10.250.50.70 ... hmac_ok=True`, `ref='refs/heads/main'`,
`-> 202 deploying` → green deploy of the latest main SHA.
- **Red-run push-notify** via an **althing relay on nh3-dev** (`soong-ci-relay.timer`,
2-min poll of corviduo's `last-deploy.json` → pings **soong-dev** via althing on a
NEW red run; green runs stay silent = fire-and-forget). corviduo itself has no
althing, so the relay lives on nh3-dev (which does), needing no gitea write token
on the Worldtree-team VM. Files: `services/soong-lab-ci/soong-ci-relay.{sh,service,timer}`;
state `~/.local/state/soong-ci-relay/last-at.txt`. (A gitea commit-status was the
alternative but needs a write token gitea won't mint without basic-auth.)
- Test suite: `uv run pytest` in `backend/` (242 tests as of v0.3.6).

# Storetank image-models archive — curation / migration / decommission record
**Host:** irv-ml1 · **Former path:** `/storetank/image-models/comfy/models`
(was the native `/opt/ComfyUI/models` symlink target).
**Status: DECOMMISSIONED 2026-06-13** — emptied of all models (919 G → 0). The
active model tree is arbo's `/storetank/arbo/models` — see
[`arbo-comfyui-model-catalog.md`](arbo-comfyui-model-catalog.md).
Historical record of how the 919 G CivitAI-managed pile was resolved on 2026-06-13:
**~739 G killed** (superseded / niche), **177 G migrated** into the arbo set, the
remainder dupes arbo already had.
## 1. Killed — superseded by arbo's current-gen stack (~739 G)
Two principles: generation-locked LoRAs have no value without their (also-superseded)
base models, and arbo already carries its own copies of the shared encoders/VAEs.
| Killed | Size | Why |
|---|---|---|
| **Hunyuan video** (diffusion_models + unet + vae + loras) | 74 G | older video arch; not in arbo |
| **WAN2.1 bases + loras** | 118 G | superseded by arbo's WAN2.2; loras gen-locked |
| **WAN2.1 encoders / VAE** (umt5, xlm-roberta, clip_vision_h, wan VAE) | 44 G | dupes of arbo's own copies |
| **FLUX.1 — everything** (dev/schnell/fill + ~20 community merges + loras + flux controlnets / redux / pulid / clip-vision / FLUX.D encoder / Florence-2-Flux) | 445 G | superseded by arbo's FLUX.2-klein; loras gen-locked |
| **orphaned umt5** (root `umt5_xxl_fp8`) | 6.7 G | last WAN remnant |
| **orphaned llava_llama3** (fp16 + fp8) | 23.5 G | HunyuanVideo's text encoder — dead after the Hunyuan kill |
| **Chroma v10/v11 + SD3.5-large** | 28 G | niche generators, not in arbo |
| **TOTAL** | **~739 G** | |
## 2. Migrated into arbo (177 G)
Everything not superseded moved into `/storetank/arbo/models` (same-filesystem atomic
move, skip-existing so arbo's production copies were never clobbered; 652 files moved,
37 skipped as dupes):
- **Gen-agnostic utilities:** Aura-SR v1/v2 + the full `upscale_models/` family
(HAT/DAT/RealESRGAN/UltraSharp/Remacri/NMKD/Omni-SR) · Florence-2 + CogFlorence
captioners (`LLM/` + `florence2/`) · controlnet_union_promax · grounding-dino ·
SAM + SAM-HQ · yolo (`ultralytics/`) · depthanything-v2 · vitmatte · nsfw_detector ·
insightface (inswapper + antelopev2) · facerestore · facexlib · ip-adapter-plus_sdxl ·
CLIP-vision (sigclip, EVA02-CLIP-L)
- **SDXL / Pony stack:** ponyRealism, cyberrealisticPony_v8, lustify, hassaku,
waiNSFWIllustrious, juggernaut / dreamshaper Lightning, SUPIR + loras
(dmd2_sdxl_4step, ACE++, Illustrious/PonyXL character-design)
comfy-dev owns the follow-on: per-model catalog entries + graphs + heroes that turn
these files into usable arbo workflows.
## 3. Final state
`/storetank/image-models/comfy/models` (= native `/opt/ComfyUI/models`) holds only
empty category dirs + `put_*_here` placeholders — **638 K, no models**. Decommissioned;
arbo is the single live tree.

`[2026-07-23→25]` **Worldtree #376 config-divergence arc — wyrd grant fixed, drift guard demoted, per-instance config ruled BY DESIGN.**
**Trigger.** wyrd-dev needed `session.history.write` on the DEMO Worldtree (operator-approved) — add `wyrd-dev` to the `session-history-write-ratatoskr` policy rule. Attempting it surfaced that the demo runtime `/opt/worldtree/config/policies.yaml` (mtime Jul-17) had **silently diverged from the repo** — missing whole rules, not a faithful copy of any revision. Refused to hand-edit a divergent authz file on a managed box; worldtree-dev prescribed a **wholesale replace** with `main@55f3fde`. Executed (backup → replace → `docker restart worldtree-worldtree-api-1` same-image → health-gate → verify) — grant live, demo policies at parity. **This was the ONE genuine bug of the arc:** a demo-intended grant that wasn't ON demo.
**Drift guard (#376).** worldtree-dev shipped a startup guard (b131/`62b85e3`) that hashes mounted config vs the image's baked copy, logging `CONFIG DRIFT (#376)`. First reading found MORE drift: `model_roles.yaml` on both instances + personal `policies.yaml`. Captured the three runtime-vs-baked diffs (read-only) → all had **runtime-only content** (personal's `agent_architect` role + `ratatoskr-affect-full-allow` rule — live-bridged, ahead of repo). The guard's STOP-on-runtime-only rule earned its keep: a blind "sync to repo" would've deleted legitimate per-instance config.
**Operator ruling (2026-07-25 — the reframe).** Worldtree will run dozens-to-hundreds of instances at v1, each configured for its env. **Per-instance config deltas are the DESIGN, not rot; back-streaming to the canonical repo doesn't scale.** Everything stood down: demo model_roles normalize withdrawn, personal sync cancelled, post-mortem dissolved, `.bak` deleted. Guard demoted b132/`ad596b5` from ERROR alarm to INFO `CONFIG BASELINE (#376)` breadcrumb (WARNING only for a mounted file *entirely absent* = breakage-adjacent). Breaking-change protection stays in `core.config_validator`'s boot gate.
**infra-ops watcher — built then retired same day.** Wired an off-box `wt-drift-watch` (systemd --user timer on nh3-dev, alerts worldtree-dev on new `CONFIG DRIFT` startup lines) — then RETIRED it per the ruling (the error line is going away). Lesson banked in auto-memory `reference_worldtree_perinstance_config`.
**Governance notes worth keeping:**
- The auto-mode guard **blocked** a peer-green-lit (worldtree-dev) config replace on the managed demo box because there was no *operator* consent for that specific change — correct: a config-mutation+restart on shared infra needs the operator's yes, not just a peer's. Surfaced it; the operator later stood the whole thing down. Good governance on both ends.
- This arc is the direct evidence base for the [[2026-07-25-infra-ops-wt-config-repo]] decision (infra-ops owns config-as-code so live-edits stop being untracked).

- Image `muninn-gate:0.0.14` — no Dockerfile upstream, so infra-ops owns containerization. `python:3.11-slim` + `uv pip install .`; **`muninn-dispatch==0.1.4` from the internal Gitea index** (`[tool.uv.sources]`, `uv pip install .` honored the pin), token passed as a **BuildKit secret** (`--secret id=gitea_pw`) so it never lands in a layer. Built on corviduo-dev.
- **`ingestion_root: /data/state/ingestion`** — the `worldtree-personal_worldtree-state` docker volume mounted at `/data/state`, byte-identical to the watcher's view. **Acceptance criterion (muninn-dev's): `/health` → `watcher.running: true` PROVES byte-identity** (the gate reads the heartbeat the watcher writes); `no_heartbeat` with the watcher up = root mismatch. Verified true first boot.
- **`user: "1000:1000"`** — the ingestion dir is `vh:vh 0755`, so a non-root gate had to run as uid 1000 to WRITE the queue (my Dockerfile's `USER gate`/10014 would've been denied; the watcher itself runs as root and bypasses perms). This uid requirement was a genuine spec gap — muninn-dev added it to the contract (`084526e`, vh:vh 0755 + 1000:1000 as the worked example) so no future deployer re-derives it. `ingestion_root_writable: true` in `/health` is the post-deploy confirmation.
- **staging `/mnt/muninn-staging/mimir-inbox`** — bound `:ro`, SAME absolute path in BOTH the gate AND the watcher (dispatch stores paths absolutely; the watcher opens them at claim time). worldtree-dev added the watcher-side bind (their image) in **b162** (`${MUNINN_STAGING_DIR:-…}:/mnt/muninn-staging/mimir-inbox:ro`). Currently a **LOCAL placeholder dir** on corviduo-dev.
- config (single-writer) `/opt/docker/conf/muninn-gate/muninn-gate.yaml` (0600, 1000:1000). Schema CLOSED (unknown field = boot failure). 2 bearer keys minted: `mimir-inbox` [read,submit], `ops-curl` [read,submit,control]. `network_mode: host`; health probe = **`/ping`** (NOT `/health`, which is always-200 by design and would never restart the gate). Committed `786462a` (no secrets).
**Verified boot:** `/ping` `{"service":"ok"}`; `/health` (ops-curl bearer, 200) `watcher.running:true` + `ingestion_root_writable:true`. muninn-dev independently poked the live gate — auth/route surface all held (401s w/ `WWW-Authenticate: Bearer`, the 4 FastAPI default routes gone, error-envelope-not-307 on trailing slashes = bug-hunt findings 5+6 confirmed outside pytest).
**DEFERRED (the submit path) — the mimir-inbox era:** SUBMIT returns `not_found` against the placeholder staging (correct, not a defect — muninn-dev confirmed) until the real staging dir + a mimir-inbox writer exist. ~~Operator ruled shared mount (mimir-inbox stays off-box, writes to a shared/NFS mount both gate + watcher bind at the same path).~~ **SUPERSEDED 2026-08-01 — operator REVERSED to CO-LOCATE:** mimir-inbox runs ON corviduo-dev, alongside the gate + watcher, staging = a corviduo-dev-LOCAL dir (not NFS). Reason the off-box/NFS call fell: muninn-dev's code-check showed staging is NOT same-fs-constrained (gate reads staging metadata + passes path strings; `os.replace` is inside `ingestion_root`), so staging's real constraint is **path identity across writer/gate/watcher**, which co-location buys outright — and it sidesteps the NFS failure modes (path-identity break, TOCTOU widening, stale handles, a hung mount blocking `resolve(strict=True)` — the last of which blocks mimir-inbox's *event loop*, not just a threadpool worker, since its staging check is in an async handler). Ruling relayed 3× (muninn-dev ×2 w/ msg-id citations, mimir-dev ×2) + operator in-session; **mimir-inbox key handed over 2026-08-01** (bumped to [read,submit,control], 0600 drop on nh3-dev). Tail on the co-locate ruling: raise worldtree-dev (box-side provisioning + the watcher claim-semantics open Q) → provision the real corviduo-dev-local `/mnt/muninn-staging/mimir-inbox` (uid = mimir-inbox's runtime identity, rw-writer / ro-gate+watcher) → 0600 key drop on corviduo-dev → muninn-dev's **one-file path-agreement probe** → acceptance. NB gate submit surface = **`POST /jobs`** (path-addressed; NO `POST /upload` — upload deferred v0, gate never ingests bytes). `staging_roots` already allowlists the path (no gate-config change).
**RESOLVED 2026-08-01 (worldtree-dev, from source `core/muninn/runner.py:362-367`):** the watcher **OPENS the staged file in place** at claim (`parse_document(file_path)` on the dispatch-recorded absolute path) — it never moves/copies the source into the job dir (job dir holds DERIVED artifacts only). Consequences: (1) staging needs **PATH IDENTITY only**, so **co-location is a CONVENIENCE, not a requirement** — the parked multi-host option stays fully viable with a shared mount at the same absolute path on both hosts. (2) The real same-fs constraint is `.enqueue-tmp/` → `os.replace` into `pending/`, same-fs with `ingestion_root` — never staging (confirms muninn-dev). (3) **⚠️ OPERATIONAL RULE for mimir-inbox lifecycle (worldtree-dev):** open-in-place means the staged file MUST stay present+readable from submit **until the job is TERMINAL** (complete / failed-and-not-retried) — retry re-runs the structure phase, which re-opens the staged path. A cleanup that deletes on 201-submit kills every job at claim with a not-found that looks EXACTLY like the namespace-mismatch failure the bind exists to prevent. Relayed to mimir-dev for their cleanup design. **Gate-side edge (muninn-dev):** `POST /jobs/{id}/retry` returns `200 {requeued}` even for a job whose staged source was deleted — `muninn_dispatch.requeue` validates job STATE not file existence, and admission isn't re-run on retry (nothing re-stats files) → a FALSE success that dies at claim. Gate deliberately unguarded (re-admit re-resolves under a new clock, still races; lifecycle is the writer's), recorded as a gate compatibility constraint. So the retention rule isn't just "avoid claim-fail" — it's "retry will LIE with a 200 if the source is gone."
**worldtree-dev approved co-location** (2026-08-01): another small infra-ops-managed LAN/WG-internal service on corviduo-dev in the gate's posture is fine at their OS/app layer; port/supervision/identity mine to shape; staging-dir ownership flip (mimir-inbox-writable, gate+watcher :ro — b162 watcher bind already :ro) at my convenience. **NEXT: coordinate the mimir-inbox deploy inputs with mimir-dev** (image/build recipe — likely infra-ops containerizes like muninn-gate; app config/env; port), then provision staging dir + stand up the service (uid 1000, matching the corviduo-dev muninn stack) + 0600 key drop on corviduo-dev + muninn-dev's path-agreement probe + acceptance.
**Operational guard (no auto-check exists):** docker fabricates a MISSING bind source as an empty dir that passes every closed-config check → **confirm the host mount actually exists before wiring/repointing a bind** (`os.path.ismount` breaks on subdir roots; emptiness is normal pre-first-upload). This is why the gate/watcher path-agreement is an operational discipline, not a validated invariant.
**Hardening candidate (flagged, not done):** the compose mounts the WHOLE `worldtree-personal_worldtree-state` volume at `/data/state` per muninn-dev's spec; a subpath mount of just `ingestion` → `/data/state/ingestion` would be tighter (gate only needs RW on ingestion). Confirm with muninn-dev before adopting.

- `[2026-08-05]` **Fleet CI resilience — DEFAULT_ACTIONS_URL=self flip ATTEMPTED end-to-end, PARKED on a runner-auth blocker. Infra-ops to research the runner action-fetch auth, later (operator-directed 2026-08-05, deferred — not now; untracked, no issue).**
**Goal (worldtree-dev's operator-directed filing, run-9189 evidence):** every Gitea Actions job hard-depends on **github.com** at step zero — `act_runner` resolves bare `uses:` refs (checkout/cache/setup-uv/etc.) against github at job start. A GitHub blip froze a real deploy (run 9189, `connection reset` cloning `actions/checkout`). Fix = mirror the action repos into Gitea + point `DEFAULT_ACTIONS_URL` at self, so github can be down and fleet CI doesn't care.
**What's DONE + staged (all reversible, still in place):**
- **Fleet `uses:` audit** (scripts in `/tmp/claude-1000/gitea_uses_audit.py`, run via ana-docker localhost API): 71 repos, 23 with workflows, but the raw ~42 action count is **almost all dormant vendored-OSS mirrors** (0 Action runs). The **actually-running CI repos** (Worldtree/arbo/althing/skaldsong/asset-engine/vor/task-board/nevermore/mead-hall/soong-lab) use just **7 action repos**.
- **7 mirrors created + populated + public** under gitea orgs **`actions`** + **`astral-sh`**: checkout, cache, upload-artifact, download-artifact, setup-node, setup-python, astral-sh/setup-uv. All in-use tags verified present (checkout@v4/v6, cache@v4, up/download-artifact@v3, setup-node@v4, setup-python@v5, setup-uv@v3/v5/v7). **Actions DISABLED on all 7** (they're source mirrors; don't want their own CI). Repos are PUBLIC.
- **Gitea = 1.26.1, container `gitea` on ana-docker; runner = `gitea-runner` (act_runner v0.6.0), label `pfi-fleet`, jobs run in a `container:`.**
**Mirror-creation FOOT-GUN (paid for):** gitea's **migrate-from-github is flaky** — migrations ran 227–531s then 422'd, leaving broken empty repos (only cache synced). And **github throttles ana-docker's colo IP** after a clone burst (same pattern as the original github dependency). **The reliable method: plain `git clone --mirror` on nh3-dev (residential egress) + push to gitea via git-SSH `ssh://git@10.250.50.70:222` (auths as vh from nh3-dev).** That populated the last 3 cleanly. Use that, not the gitea migrate API, to (re)build mirrors.
**THE BLOCKER (why it's parked):** with `DEFAULT_ACTIONS_URL=self`, the runner correctly resolves `uses: actions/checkout@v4` → `https://gitea.phasefinal.com/actions/checkout` (confirmed in the runner log + the decompressed job log at `/data/gitea/actions_log/vh/<repo>/*.log.zst` — **zstd, decompress on the ana-docker HOST, not in the gitea container which lacks zstd**). But the fetch **fails on auth**: `authentication required: Invalid username or token. Password authentication is not supported for Git operations.` The runner is **NOT** fetching anonymously — it **sends a credential gitea rejects**. So `REQUIRE_SIGNIN_VIEW=false` did NOT fix it (that would only help an anonymous fetch; anon clone of the public mirror does work now). The real issue is **how act_runner v0.6.0 authenticates its action-fetch to a gitea 1.26 instance** — that's the research task.
**Current CONFIG STATE (post-revert):** `DEFAULT_ACTIONS_URL` is **REMOVED** from gitea app.ini → **back to github default (CI works normally)**. **`REQUIRE_SIGNIN_VIEW = false` was SET and KEPT** (operator: "require_signin_view false on internal wg net") — now a **standing change** on the internal WG net (anon view of PUBLIC repos only; private repos stay auth-gated). app.ini backups on the box: `/data/gitea/conf/app.ini.bak-*` (signinflip / revert / actions).
**Smoke method (for when re-attempting):** create a throwaway `vh/actions-smoke` repo with a minimal `runs-on: pfi-fleet` + `container: python:3.11.10-slim-bookworm` + `uses: actions/checkout@v4` + `echo` workflow (adding the workflow file triggers `on: push`); poll `/repos/vh/actions-smoke/actions/tasks`. `ci.yml` has NO `workflow_dispatch` and the run **rerun API 404s** on 1.26 — pushing a commit is the trigger. SUCCESS = the checkout step resolves from the local mirror.
**NEXT STEP (my deferred task):** research act_runner's action-fetch auth on gitea 1.26 (how it should authenticate; a runner config token, a gitea setting, or a version constraint). worldtree-dev (filer, runs gitea CI daily) offered as an alternative but operator directed **infra-ops** to do it. Everything's staged for a clean re-attempt once the auth path is understood; if dropped, tear down the `actions`/`astral-sh` orgs + 7 mirrors. Related: `[[2026-08-03-worldtree-b168-384-385-arc]]` (the gitea-CI stack context).

`[2026-08-11]` **stonehenge-park — new fleet `/park` service repo stood up + designed.**
**What.** A separate greenfield repo (`~/development/stonehenge-park`, gitea `vh/stonehenge-park`,
pushed) for a self-contained `/park` service: one durable place to park any idea (repo-born OR
personal), find it by search, and have it **actively resurface** (by due-date or staleness) until
acted on — so parked ideas stop dying when a repo goes cold. NOT part of eshpfi; this is a pointer.
**Design (via `/vor-plan`, converged + persisted to `docs/design/`):** four contract-sized units —
**U1** core store+API (SQLite+FTS5, slug minting, bearer auth, REST) — the tracer, build first; **U2**
scheduler+notifier (in-process; due/stale → statusline `due-count` + althing push to a dedicated
**assistant channel**; keep-surfacing until promote/drop/re-snooze); **U3** `park` CLI (mirrors the
`secret` CLI); **U4** browse UI. `/vor-ui` ran too (U4 brief persisted).
**Locked decisions (operator):** SQLite, self-contained, ONE container, no external DB ("don't want
to troubleshoot it when a database upgrade happens") — a hard `[OPS]` invariant; system-minted
title-derived slugs + short ID (addressable as `park/<slug>`); active keep-surfacing resurfacing with
**re-snooze as the anti-nag valve**; bearer key, LAN/WG-internal; host nh3-docker; `/park` **replaces**
the global ROADMAP parking-lot discipline (deferred ideas → `/park`, `source`-tagged; ROADMAP keeps
only the v1 target) as a **fast-follow after v1** incl. migrating existing lots.
**Deferred (in the plan):** the althing assistant-channel handle **name** (decide at U2 contract
time); staleness threshold + re-push cadence (env-tunable defaults ~30d/~daily); design U2's emit
structured/consumable so a future **mission-control (Ledger→orchestrator)** can read it — park does
NOT build the orchestrator.
**State.** Pre-seeded for a fresh agent (CLAUDE/persistent-memory/ROADMAP/README + the design docs),
committed (`294ee98`), pushed. Next build task lives in that repo: the **U1 tracer contract** under
the House Code Discipline. Auto-memory candidate not yet written (repo is self-documenting).

# eRP dual-seat overhaul — MeroMero-v2 + Dark-Scarlett, NVFP4A16 @ 256K on ana-ml2
`[2026-08-12]` Replaced the two legacy char-rp seats with home-quantized NVFP4A16 vLLM
seats. Operator-driven, end to end this session.
## What landed
| Seat (LiteLLM alias) | Model | Role | GPU | Context |
|---|---|---|---|---|
| `char-rp` (:8016) | **G4-MeroMero-v2-31B** (Gemma-4) | non-thinking PROSE, **multimodal (vision)** | GPU0 | 256K @ 2.07× (util 0.52) |
| `char-rp-reasoning` (:8018) | **Dark-Scarlett-v1.0-27B** (Qwen3.6) | THINKING (default) | GPU1 | 256K @ 1.62× (util 0.44) |
- Both **NVFP4A16 weight-only** (llm-compressor, `compressed-tensors`), `--kv-cache-dtype fp8`.
- Replace: `char-rp-gguf` (Magidonia-24B GGUF/llama.cpp, :8016) + `heretic2-charrp-reasoning`
(DavidAU Qwen3.6-27B-Heretic2 modelopt NVFP4+MTP, :8018). Old stacks/containers **stopped +
retained** for rollback.
- Compose-ified: `stacks/meromero-charrp` + `stacks/darkscarlett-charrp-reasoning` (ana-ml2
`/opt/docker/compose/`, mirrored to eshpfi, commit **`f08b6cb`**) → survive reboot.
- Research that drove picks: `docs/pfi/erp-thinking-finetunes-2026.md` (from the `gecko-65` Booth).
## Load-bearing lessons (the whole point of this file)
1. **Load via the ConditionalGeneration WRAPPER class, never `AutoModelForCausalLM`.** For a
multimodal-capable base (Gemma-4, Qwen3.6), `AutoModelForCausalLM.from_pretrained` +
`save_pretrained` writes a FLAT text config (`Qwen3_5TextConfig`, `model.layers.*`) that
**both vLLM AND SGLang reject** (SGLang: "Qwen3_5ForCausalLM has no SGLang implementation";
vLLM wants `Qwen3_5ForConditionalGeneration`). Loading via `Qwen3_5ForConditionalGeneration` /
`Gemma4ForConditionalGeneration` keeps the wrapper config they accept. **This was the DS
blocker** — re-quant via the wrapper fixed it (`Dark-Scarlett-...-NVFP4A16-wrapper`).
2. **NVFP4A16 is weight-only → DATA-FREE.** llm-compressor infers `DataFreePipeline`; calibration
data is unused (only matters for W4A4 activation quant). W4A16 chosen per NVIDIA's sm_120
long-context guidance (W4A4 KLD 2-4× worse past ~10k ctx).
3. **Load on CPU (`device_map=None`)** so llm-compressor onloads one layer at a time. `device_map=
"auto"` packs the whole model onto the GPU and OOMs when the card isn't fully free.
4. **Both models are KV-EFFICIENT — the "dense = KV-hungry" worry was WRONG.** MeroMero (Gemma-4)
uses **sliding-window attention** (most layers cache only a bounded window); DS (Qwen3.6) uses
**hybrid GatedDeltaNet linear-attention** (3:1 linear:full, linear layers carry no KV). Both
hit full native 256K easily. (MeroMero KV pool ~542K tokens at util 0.52.)
5. **MeroMero vision reconstruction.** The finetune ships `processor_config.json` (image_processor
inline, `Gemma4ImageProcessor`) but NOT `preprocessor_config.json` — the old-format file vLLM's
feature-extractor loader wants. **Even google/gemma-4-31B-it (ungated!) ships only
processor_config.json.** FIX: extract the `image_processor` section → write
`preprocessor_config.json` verbatim, serve WITHOUT `--language-model-only`. Verified (model
correctly ID'd a red circle). Audio is config-declared but WEIGHTLESS (0 audio tensors).
6. **GPU placement.** Match the KV-heavier model to the roomier GPU. GPU0 (gen neighbor, ~54GB
free) > GPU1 (utility cluster, ~45GB free). Swapped MeroMero→GPU0, DS→GPU1. Pins via compose
`deploy.resources.reservations.devices`.
## Dead ends (tried + abandoned)
- **DS via llm-compressor `AutoModelForCausalLM`** → flat config vLLM/SGLang reject. → wrapper class.
- **DS via NVIDIA ModelOpt** → modelopt↔transformers **version deadlock**: current transformers
supports `qwen3_5` but crashes modelopt's sparse-moe plugin (`issubclass()` on a non-class);
modelopt 0.43.0 pulls an old transformers that can't load `qwen3_5` at all. Abandoned.
- **DS via SGLang** → `Qwen3_5ForCausalLM has no SGLang implementation`. Abandoned, but it REVEALED
that both engines need the wrapper (→ the fix in lesson 1).
- **`device_map="auto"` for the quant** → CUDA OOM in the weight observer. → `device_map=None`.
## granite retired + gateway repoint
- `vllm-granite` (granite-4.1-8b, fleet summarizer, GPU1) **`docker stop`ped** (reversible) to
reclaim ~13.6GB GPU1 for RP context.
- LiteLLM (`ana-docker:/opt/docker/conf/litellm/config.yaml`, backed up
`.bak-pre-granite-down-*`): **`granite-4.1-8b` alias RETIRED** — commented out, now 404s cleanly
(the `*` wildcard→llama-swap was decommissioned 2026-06-20, so no fallthrough). **`summarizer` +
`classifier` REPOINTED to gen** (`hosted_vllm/qwen3.6-35b-a3b-heretic` @ :8015,
`enable_thinking:false`) — both verified. ⚠ This LiteLLM change is **server-only / not
version-controlled** (a follow-up).
## MTP — deferred
DS's MTP heads were dropped by the CausalLM loader; **deferred, not restored** (spec-decode is
net-negative at RP temps: ~38-52% accept at temp 0.8-1.25, below vLLM's 0.5 cutoff). The
splice-back path (`splice_mtp.py` in the heretic2 work dir) exists if ever wanted. MeroMero
(Gemma-4) has no MTP by architecture.
## On-disk / where things live
- Quant pipelines: `ana-ml2:/tank/aimodels/meromero-v2-nvfp4-work/` +
`/tank/aimodels/darkscarlett-nvfp4-work/` (scripts, BF16 source, NVFP4 outputs).
- Compose stacks: `ana-ml2:/opt/docker/compose/{meromero-charrp,darkscarlett-charrp-reasoning}/`.
- Gateway aliases (unchanged, port-based): `char-rp`→:8016, `char-rp-reasoning`→:8018. (char-rp was
also fixed from the stale `magidonia-24b-v4.3` backend model name → `char-rp`.)
## Open follow-ups
1. LiteLLM granite/repoint change NOT version-controlled (server + backup only).
2. eshpfi unpushed (many commits this session incl. `f08b6cb`, `7bd7375`, `398b58a`).
3. MTP deferred (see above).
4. DS thinks verbosely (~13:1 reasoning:content) — eval item; consumers need generous `max_tokens`.
5. MeroMero full 256K needs util 0.55 (GPU0 ~1.8GB free, tight); ran at 0.52 for headroom (~4.6GB).

`[2026-08-10→12]` **secrets-broker — per-box Vaultwarden credential store, SHIPPED + consumer-confirmed.**
**What.** A per-dev-box credential store over the fleet Vaultwarden (`vaultwarden.phasefinal.com`,
on ana-docker, DB on pfi-postgres, in the pg_dump backup set). The `secret` CLI at eshpfi
`services/secrets-broker/secret` (also installed to `~/.local/bin/secret`, on PATH for all sessions):
`put / get / list / rm / backfill`. Stores into the **`infra-ops` org's Default collection** (org
shared to the operator's primary account, so he sees items too), folder = hostname, item name =
`<host>/<path>`, title-derived slug. Small text → item note; small binary → base64 hidden field;
**>6000 B → a bw attachment** (Vaultwarden caps notes at ~10000 encrypted chars); sha256 + source
metadata fields; idempotent upsert keyed by name.
**Auth.** Bootstraps from `~/.config/secrets-broker/bootstrap.env` (0600): apikey login
(`BW_CLIENTID`/`BW_CLIENTSECRET`) + master-password unlock (`--passwordenv`) → per-invocation
session. That file is **secrets-zero** (it unlocks the vault, can't live in it) and is excluded from
backfill.
**Client = `bw`, NOT `rbw`.** rbw was the operator's first choice but its `register` returned an
undebuggable 400 against this Vaultwarden despite valid creds (a direct `client_credentials` grant +
both prelogin paths return 200; rbw emits no HTTP logs). Switched to the official `bw` CLI
(user-prefix npm install) — clean unattended flow, full write support (org collections + attachments).
**Backfill.** Local-only (each box backs up itself; NOT a fleet daemon). Scanned nh3-dev's
`~/development/*/{env.sh,.env}` + `~/.config` credential files, **25 items stored + round-trip
verified** (2 large via attachment). Excludes bootstrap.env / `.example` / `~/AIPA-Data` archives /
cargo noise.
**Post-launch (jackdaw-dev feedback).** Added **`secret rm <name>`** (bw soft-delete to trash,
recoverable) — closes the "no delete path, append-only" gap; and a **new-top-level-namespace warning**
on `put` (stderr, non-blocking) — catches a typo'd/missing host prefix at store time. Chose
warn-not-auto-prefix because domain-scoped names (`gitea/…`, `certs/…`) would misfire on auto-prefix.
Deferred edge recorded in the contract: the warning is non-blocking, so a scripted put suppressing
stderr can still mis-namespace — add an opt-in `--strict` only if scripted callers appear.
**Standing directive (now GLOBAL in `~/.claude/CLAUDE.md`):** the vault is the credential source of
truth — **`secret put` durable secrets into it AND `secret get` the creds a task needs FROM it**
rather than reading on-disk copies. Dogfooded by pulling the gitea `vh` token from the vault to create
`vh/stonehenge-park`.
**Deploy shape.** Not a service / no daemon — per-box; a new dev box duplicates the stack
(`services/secrets-broker/README.md`): npm-install `bw` to `~/.local`, drop a per-box `bootstrap.env`,
`secret backfill`. Commits: `41359ea` (CLI + contract), `850a197` (backfill 25/25 + attachment +
resilient run), `a249073` (rm + namespace warning), `a1304b7` (deferred-edge contract note).
Consumer-confirmed end-to-end by jackdaw-dev.

# gen-seat mixed NVFP4+FP8 requant + char-rp tool-parser fix (2026-08-15, overnight)
Autonomous overnight session. Two operator-queued items, both closed.
## 1. char-rp / MeroMero tool-call parser (parked since the prior session)
**Symptom:** every tools-bearing request to `char-rp` (:8016) returned
`400 "auto" tool choice requires --enable-auto-tool-choice and --tool-call-parser`.
The seat had **no tool parser configured at all** — the migration from the
Magidonia GGUF seat dropped it.
**Fix.** MeroMero-v2 is Gemma-4 and emits its own native
`<|tool_call>call:name{...}<tool_call|>` syntax, not the qwen3_coder XML the
Qwen-family seats use. vLLM 0.24 ships a `gemma4` tool parser whose
TOOL_CALL_START/END + CHANNEL_START/END + escape constants match this
tokenizer's `etc_token`/`eoc_token`/`escape_token` exactly (verified before
deploying, not assumed).
Four flags, and they are a **set**:
```
--tool-call-parser gemma4
--enable-auto-tool-choice
--reasoning-parser gemma4
--default-chat-template-kwargs '{"enable_thinking": false}'
```
- Without the **reasoning parser**, the post-tool-response turn leaks a literal
`<|channel>thought\n<channel|>` prefix into `content` (upstream vllm #45834 —
the chat template leaves the prompt inside an open channel block).
- The **`enable_thinking: false`** is mandatory, not cosmetic. The parser reads
it from `chat_template_kwargs` and **defaults it to `True`**
(`vllm/parser/gemma4.py:439`). True → `is_reasoning_end()` returns False at a
new turn → engine pre-initialises to REASONING → **all plain RP prose lands in
`reasoning_content` and `content` comes back null**, breaking every char-rp
consumer. Caught by reading the parser before deploying it.
- **Zero behavioural risk, proven not asserted:** `chat_template.jinja:350`
already defaults `enable_thinking` to false, so passing it explicitly renders a
**byte-identical prompt** — diffed across plain / with-tools / post-tool-response
/ system-prompt shapes before the flag went anywhere near the live seat.
Verified green: tool call (streaming + non-streaming), tool-result round-trip
(leak gone), plain prose in `content` with `reasoning` null, vision. Commit
`b8f0f4c`.
## 2. gen seat requant — the "W4A8" framing was wrong
**The queued task was not servable as specified.** vLLM 0.24's compressed-tensors
dispatcher (`compressed_tensors.py:704-713`) accepts NVFP4 weights with exactly
two activation options — `None` (W4A16, which **forces the Marlin kernel**,
`kernels/linear/__init__.py:881-883`) or NVFP4 (W4A4). Anything else, FP8
included, raises `ValueError: For NVFP4 weights, input quantization must also be
NVFP4 format`. `CompressedTensorsW4A8Fp8` exists but is **INT4** weights
(`W4A8_SUPPORTED_TYPES_MAP = {4: int4}`) gated on `_check_scheme_supported(90,
match_exact=True)` — Hopper only, so on Blackwell it is closed twice over.
The ~20% intuition was right; the *scheme name* was wrong. FP8 has to enter
**per-layer-group**, not as activations on NVFP4 weights.
**Two baseline corrections.** The handoff's "~68 tok/s, ~42% acceptance" did not
reproduce. Cache-busted (unique prompt per run — with a fixed prompt, prefix
caching returns byte-identical timings and you measure nothing), the incumbent
W4A16 build already did **80.12 tok/s at 47.8% acceptance** — i.e. essentially
*at* the handoff's stated W4A8 target of ~82. Had that not been re-measured the
whole chase would have been declared a success for doing nothing.
**The shortcut that saved hours.** `unsloth/Qwen3.8-27B-NVFP4` was already on-box
(pulled the previous day) — same architecture, same size, a published
mixed-precision scheme. Serving it as a probe measured **+19.1% at identical MTP
acceptance** — proving the gain was real and kernel-level *before* committing to
a requant. Its config was then read out as the reference recipe.
**The recipe** (byte-for-byte unsloth's, applied to the abliterated weights):
| group | scheme | targets |
|---|---|---|
| `group_0` | FP8 W8A8, channel weights + per-token dynamic acts | `self_attn.{q,k,v,o}_proj`, `linear_attn.{in_proj_qkv,in_proj_z,out_proj}`, `lm_head`, **layers 56-63** MLPs |
| `group_1` | NVFP4 W4A4, tensor_group gsize16, fp8 scales, `imatrix_mse` weights, `dynamic:"local"` acts | **layers 0-55** MLP `{gate,up,down}_proj` |
| kv | FP8 static tensor | — |
| ignore | vision tower, `linear_attn.{norm,in_proj_a,in_proj_b}`, `re:^mtp.*` | — |
Holding the **last 8 layers' MLPs at FP8** is the accuracy trick. Targets were
made explicitly non-overlapping (group_1 enumerates 0-55) rather than trusting
group precedence, and `validate_targets.py` proved coverage against real module
names — 0 overlap, MLP union = layers 0-63 — before any GPU time was spent.
**Results (cache-busted, bs=1):**
| metric | W4A16 | mixed | delta |
|---|---|---|---|
| decode tok/s | 80.12 | **94.53** | **+18.0%** |
| prefill tok/s (~6.7k prompt) | 3,206 | **6,334** | **+98%** |
| prefill tok/s (~27k prompt) | 2,862 | **5,085** | **+78%** |
| TTFT on a ~27k doc | 9.43 s | **5.31 s** | −44% |
| MTP acceptance | 47.8% | 47.7% | unchanged |
| perplexity (6 passages) | 6.941 | 7.059 | +1.7% worse |
| abliteration compliance | 4/4 | 4/4 | preserved |
| weights on disk | 27.7 GB | 22.5 GB | −19% |
Surface test 6/6 on the live seat (plain chat, vision, tool calling, thinking
split, 36K-token needle retrieval, streaming); all 7 LiteLLM aliases verified
routing. Commit `74f596b`.
## Foot-guns banked
- **`llm-compressor` PRUNES `ignore` entries that matched no module at quant
time.** The wrapper class never loads the MTP head, so `re:^mtp.*` matched
nothing and was silently dropped from the saved config — the exact bug that
cost two prior rounds (vLLM then loads the grafted BF16 MTP as quantized →
uninitialised → 0% acceptance). `post_quant.py` now **re-injects it after the
graft and re-verifies**. That check *fired on this run* — it was not
hypothetical.
- **Prefix caching silently fakes prefill numbers too.** The prefill harness originally used a
*seeded* nonce, so run 2 regenerated run 1's prompts verbatim and read **~41k tok/s of
cache-hit** instead of ~5k of real prefill. Same class of error as the decode bench. Use
`SystemRandom`; never seed a cache-busting nonce.
- **vLLM's `prompt_logprobs` are garbage while speculative decoding is on** —
~uniform over the vocab (median rank ~10⁵, logprob ≈ log(1/vocab); " Paris"
after "The capital of France is" ranked 69698). Perplexity must be measured on
a seat served **without** `--speculative-config`. The harness now raises rather
than reporting the garbage.
- **`gen-seat/.env` is mode 0600 / lkraven-owned** → *every* `docker compose`
call needs `sudo`. Without it compose fails `permission denied` reading `.env`,
**leaves the old container running**, and the change silently does not take —
which produced one round of "benchmark results" that were just the unchanged
baseline. Hard-verify against `docker inspect` argv after any such change.
- **GPU0 co-residency is a zero-sum budget.** The smaller mixed weights meant gen
at the old util 0.45 absorbed the slack as KV (17.0 GiB / 477K tokens) and left
meromero **0.18 GiB** short of its 0.52 → crash-loop. Fixed at
`GEN_GPU_MEM_UTIL=0.43` (15.1 GiB / 422K tokens, still 1.6× the 262K context).
Both seats now 94.4/97.9 GB.
## Measured negatives — do not re-chase
- **`GEN_SPEC_TOKENS` is already optimal at 3.** Swept on the live seat:
n=2 → 77.1, **n=3 → 80.1**, n=4 → 78.7, n=5 → 75.9 tok/s. Higher n trades
acceptance for draft width and loses.
- **W4A4-everywhere was never attempted** and should not be — the accuracy-safe
shape is precisely the mixed one (FP8 on attention + late MLPs).
## Artifacts
- Pipeline + acceptance harness + raw JSON: `services/gen-seat-mixed-quant/`
- Stack docs: `stacks/gen-seat/README.md`, `stacks/meromero-charrp/README.md`
- Rollback: `sudo cp /opt/docker/compose/gen-seat/.env.bak-w4a16-20260815 …/.env`

# [2026-08-15] Uncensored gen seat: Qwen3.8-27B-Uncensored deployed; the definitive MTP-graft fix
**Outcome.** The fleet `gen` seat is now **`JonathanColetti/Qwen3.8-27B-Uncensored`** (Heretic
abliteration, KL 0.12 vs base, bench Δ −0.5 within noise, refusals 98→12/100), quantized in-house
to **NVFP4 W4A16** (llm-compressor / compressed-tensors) with a **grafted bf16 MTP head**,
vision-intact, **262K** ctx, MTP n=3 (**~42% accept, ~68 tok/s**), coherent. Live at ana-ml2 `:8015`
(project `gen-seat` / container `vllm-gen`), backing all 7 gateway aliases.
**THE definitive lesson (resolved 3 failed attempts + one premature 50 GB delete).** A grafted bf16
MTP scored **0% on the quant but 83% at bf16** — for TWO different abliterated models. Root cause was
NEITHER the abliteration NOR the quant scheme: it was **the grafted `mtp.*` tensors missing from
`config.json` → `quantization_config.ignore`.** The wrapper-class quant DROPS the MTP before
llm-compressor sees it, so nothing gets added to `ignore`; vLLM then tries to load the bf16 MTP as
*quantized* format → "Parameter … not found in params_dict, skip loading" → uninitialized head → 0%.
**FIX: after grafting, add `re:^mtp.*` to `quantization_config.ignore`** (one line — all unsloth's
working checkpoint has). MTP jumped 0%→83% (bf16-identical). Full lesson in auto-memory
`reference_abliteration_mtp_lessons`.
**The pipeline that works (for the next VL+MTP quant, incl. the W4A8 chase):**
1. Pull bf16 (kept at `ana-ml2:/tank/aimodels/qwen38-27b-uncensored-bf16`).
2. Quant via `quant_nvfp4_qwen.py` (darkscarlett dir) = the **wrapper-class** loader
(`Qwen3_5ForConditionalGeneration`, keeps the vLLM-serveable config); container = `vllm-openai`
+ `pip install llmcompressor==0.13.0` (drags in a transformers with `qwen3_5`).
3. **Graft** the author's `model-mtp.safetensors` verbatim into the output + merge the index.
4. **Reconstruct** `preprocessor_config.json` from `processor_config.json`'s `image_processor`
sub-dict (the repo omits it → else "Can't load image processor" crash-loop).
5. **Add `re:^mtp.*` to the output config's `quantization_config.ignore`.** ← the fix.
6. Serve: `--quantization compressed-tensors --speculative-config '{"method":"qwen3_5_mtp","num_speculative_tokens":3}'`
`--mamba-cache-dtype float32 --kv-cache-dtype fp8 --reasoning-parser qwen3`.
**VRAM / full-context budget (measured).** Weights ~27 GB; hybrid attention → **only 16 of 64 layers
carry KV** → 32 KiB/token → **262K KV = 8.6 GB** (vs ~60–70 GB for a normal dense 27B). Full 262K fits
GPU0 at **util 0.45** (~43 GB) alongside meromero (~49 GB used, it's a 31B) — pre-flight rejects util
0.48 (wants 45.6 GB, only 45.5 free). `max-num-seqs 16` keeps cudagraph modest (an ad-hoc serve with
no cap OOM'd — cudagraph captured to batch-512).
**Why unsloth's `qwen3.8-27b` (the prior gen model) was faster (97 vs 68 tok/s).** ~half = quant kernel
(unsloth native NVFP4+FP8 tensor cores vs our W4A16 → Marlin dequant, ~20% even on decode — I'd
under-stated this); ~half = MTP acceptance (unsloth 55% un-ablated head vs our 42% — inherent to the
ablation, no quant fixes it). **W4A8 recovers the first ~20% (→~82 tok/s) + prefill; not the MTP half.**
**modelopt dead-end (for W4A8, avoid).** `nvidia-modelopt[hf]==0.43.0` is too old for qwen3_5's
transformers: (a) its `NVFP4_DEFAULT_CFG.quant_cfg` is a LIST but 0.43 wants a DICT (pydantic reject);
(b) it warns transformers 5.15 untested. Use **llm-compressor** for W4A8 instead (custom recipe: NVFP4
weights + FP8 input_quantizer + calibration on `heretic2-nvfp4-work/production_calib_512.jsonl`).
**Deleted (premature — the delete I owned).** `windowsxp811203/Qwen3.8-27B-Abliterated` (~79 GB) — I
declared it desync-dead off a 0% that was actually this ignore bug. Lesson: **test MTP on bf16 first;
isolate before deleting.**
Commits: eshpfi `680c30e` (deploy + rename + litellm + README), dotfiles `1d1970f` (CLAUDE.md roster) —

# esh-pve-nas — PVE root on a USB DOM: diagnosis, mitigation, migration plan
## The finding
`esh-pve-nas` (`esh-nas-pve.esteban.net`, 10.0.50.55) runs PVE root off a **USB
Disk-on-Module** — `sdq`, 7.3 GB, `ID_BUS=usb`, `ID_VENDOR=NORELSYS`, model 1081 —
carved into a 512 MB ESP + 768 MB swap + a **6 GB ext4 root** that was at **90%
(571 MB free)**.
⚠ **Operator corrected my first read: it is a DOM, not a thumb drive.** DOMs use
SLC/pSLC with a real controller, so the **284 GB written since boot is
unremarkable and wear is NOT the driver**. I had framed it as a clock ticking;
that was wrong and the correction matters. What actually justifies the work:
1. **It is on the USB bus** — a reset or re-enumeration drops the *root
filesystem* out from under a running hypervisor whose guests keep executing.
NAND quality is irrelevant to that.
2. **6 GB has no headroom** — `/usr` alone is 3.7 GB.
3. **Unmirrored**, while 928 GB of mirrored NVMe sits 96% empty.
4. **It has blocked patching for months** — the operator-visible symptom and the
real urgency.
## The patching blockage (measured)
`apt-get -s dist-upgrade`: **225 packages pending, 161 carrying `deb12uN` /
Debian-Security bumps** including `ssh 1:9.2p1-2+deb12u10`. Host sits on
`pve-manager/8.4.11` vs sibling esh-pve's **8.4.14**, with 20 weeks uptime
because it cannot take a kernel.
⚠ **Ordering is load-bearing: migrate FIRST, patch after.** The pending set
includes `proxmox-kernel-6.8.12-42-pve-signed` — ~250 MB of kernel + initramfs
landing in `/boot`, **which is on root**. Unpacking 225 packages (dpkg, perl,
glibc-adjacent) into 1.3 GB of headroom risks filling the disk mid-transaction
and wedging dpkg on a hypervisor running five guests. Partial escape hatch if
patching truly cannot wait: `apt-get -o Dir::Cache::Archives=/nvme/tmp/apt-archives`
keeps downloads off root, but the kernel still lands in `/boot`.
## Mitigation applied 2026-08-17 — root 90% → 76%
| step | effect |
|---|---|
| capped journald (`SystemMaxUse=64M`; was **fully default/uncapped**) | stops unbounded growth |
| vacuumed the journal | **freed 446 MB** |
| `apt-get clean` | 79 MB |
| `/root/neo` (2024 Intel NEO OpenCL debs) → `/nvme/tmp/root-neo-20260817/` | 259 MB — **moved, not deleted** |
| **`/var/log/journal` relocated onto ZFS** (`nvme/varlog`) | dominant writer off the DOM |
571 MB → **1.4 GB free**. All five guests stayed up; a fresh `logger` round-tripped
through the ZFS-backed journal.
⚠ **Stopping journald over SSH kills your own session** — it takes the
connection's logging path with it. The first attempt died mid-swap, leaving the
dataset staged and the move incomplete (host was never at risk; journald
socket-activated straight back). Redo as a detached `systemd-run` transient unit.
Script + reason live at `root@10.0.50.55:/root/move-journal-to-zfs.sh`.
Deliberately **not** done: moving `/var/lib/rrdcached`. With the DOM correction
the wear argument no longer justifies touching a service `pvestatd` depends on.
## The plan — split boot from root (operator's proposal, strictly better)
My first plan was a full reinstall to a mirrored-NVMe ZFS root. **The operator
proposed keeping boot on the DOM with a fallback image and putting all its files
on ZFS. That is better and I should have gotten there myself** — I had assumed
boot and root must share a device.
| | device | contents | written when |
|---|---|---|---|
| boot | DOM `sdq` | ESP + `/boot` (ext4) | only on kernel/GRUB updates |
| root | `nvme` pool | `nvme/ROOT/pve-1` | constantly, on mirrored NVMe |
Keeping `/boot` on **ext4** is the point, not a compromise: GRUB never has to read
ZFS, which matters because the `nvme` pool has `encryption`, `large_dnode` and
`zstd_compress` enabled and **GRUB cannot read those**.
**Why it beats the reinstall:** the `nvme` pool survives (no guest migration, no
`ssd`/`tank` export-import, no reinstall); downtime is **one reboot** not half a
day; **rollback is a GRUB menu entry** because the ext4 root stays untouched on
the DOM; and it retires the actual top risk — with root on NVMe a USB bus reset
mid-run no longer kills the running system. Free upside: boot environments
(`zfs snapshot nvme/ROOT/pve-1@pre-upgrade`).
**Preconditions verified already met:** UEFI + `grub-efi-amd64 2.06-13+pmx7`;
**`zfs-initramfs 2.2.8-pve1` already installed with 76 ZFS files in the running
initrd**; root only 4.3 GB to copy; swap 767 MB / 123 MB used against 125 GB RAM
(leave it on the DOM LV — **never** swap on a zvol).
**Two traps:** `canmount=noauto` on the root dataset or ZFS mounts over the live
root; and `cachefile` is `none` with a **0-byte `/etc/zfs/zpool.cache`** — pools
import by scan today, which is a coin-flip when the initramfs must find root.
Set the cachefile before rebuilding the initramfs.
Operator ruled a **cloned DOM image is sufficient** boot-path insurance (no
mirrored boot needed). `dd` it off-box before anything else; refresh after kernel
updates.
## ⚠ Blast radius — the gating constraint, invisible from the host itself
**CT 103 `esh-nas` (10.0.50.50) IS the NAS, and it runs on this host.** Two
dependents mount it over **`hard`** NFS — they do not fail, they hang unkillably:
- **esh-docker-vm** (10.0.50.45): `/mnt/books`, `/mnt/backup`
- **esh-pve** (10.0.250.35): `/mnt/pve/esh-nas`, `/mnt/pve/tank-vmbu`
Known incident shape — the only remedy for esh-docker-vm's D-state is a host
reboot, and `/mnt/books` was *deliberately* left `hard` because calibre's SQLite
risks corruption under `soft`. Quiesce both before any reboot of this host.
Recorded in `servers/esh-pve-nas/README.md` as a never-reboot-casually warning.
## Also identified
- **`esh-nas` is CT 103** on esh-pve-nas — structurally the same shape as ana-nas
being CT 109 on pfi-pve.
- **`ESH-FileBot` (CT 106, 10.0.50.70) is an empty shell** — 80 GB rootfs, six
passthrough mounts (`books`/`documents`/`music`/`share`/`pvestore`/`ssd-pvestore`),
and **nothing running but base systemd, sshd, cron, postfix** since 30 March.
That resolves the dashboard's long-standing "role TBC". Retire rather than
migrate.
- Both ESH hypervisors have **20 weeks uptime** and differing PVE patch levels.
## Staging executed 2026-08-18 — everything but the reboot
Two rerunnable elway playbooks, 0 failed steps, 17/17 verify green:
`playbooks/esh-pve-nas-stage-zfs-root.yaml` (LV surgery, `/boot` populate,
4.3 GB root rsync in 228 s, fstab) and `playbooks/esh-pve-nas-stage-bootloader.yaml`
(ZFS initramfs, grub.cfg, both menu entries, grubenv).
**`grub-install` is deliberately NOT run.** The ESP stub still points at the old
`/boot` inside the ext4 root, so the host's boot path is byte-identical to the
last 140 days and an unplanned reboot mid-staging is a non-event. Cutover is
`grub-install` + `grub-reboot pve-zfs-root` + `zfs set mountpoint=/` + reboot.
Final DOM layout: `pve-root` 6.04 G (untouched, the rollback) + `pve-boot` 512 M
(new) + `pve-swap` 256 M (was 768 M).
### The three landmines staging found
1. **The `/boot` LV had nowhere to live.** VG `pve` had **4 MB free**, and
mounted ext4 cannot shrink — freeing space from root needs a rescue boot,
which costs the "one reboot" property the design rests on. Only live source
was the swap LV. Operator chose shrink-to-256M over drop-entirely.
2. **The one-pool cachefile would have broken the NAS.** `zpool set
cachefile=… nvme` looks scoped and safe; it is the opposite. Populating a
cachefile flips the host from `zfs-import-scan` to `zfs-import-cache`
(verified: scan active, cache inactive beforehand), so a cache holding only
`nvme` leaves `ssd` and `tank` unimported at boot — and CT 103 has twelve
bind mounts spanning all three pools. Every export would come up empty and
both `hard` NFS clients would hang.
3. **`update-grub` silently emitted a pool-less `root=ZFS=/ROOT/pve-1`.**
Debian's `10_linux` builds `${rpool}${bootfs}`; `rpool` comes from
`grub-probe --target=fs_label`, which returns empty because GRUB's ZFS reader
cannot open a pool with `encryption`/`large_dnode`/`zstd_compress` — and the
probe failure is swallowed by `2>/dev/null || true`. The same feature set
that forced `/boot` to stay ext4 also corrupts the kernel command line, which
the design did not anticipate. Fixed with a `/etc/default/grub.d/zfs-root.cfg`
drop-in (last `root=` wins) plus explicit `pve-zfs-root` and
`pve-ext4-rollback` entries carrying stable ids — the auto-generated ids are
derived from pool member device paths and would shift if the mirror changed.
**The transferable lesson from (3):** the original verify grepped for
`root=ZFS=nvme/ROOT/pve-1` *appearing somewhere* in grub.cfg. Once the drop-in
was added that grep passes — while pool-less entries sit in the menu untouched.
The check that holds walks every `linux` line, takes the **last** `root=`, and
asserts it against a known-good set. **Assert the effective value, not the
presence of a substring.**
### One-shot boot, not a new default
`GRUB_DEFAULT=saved` with grubenv pinned to `pve-ext4-rollback`, and cutover uses
`grub-reboot pve-zfs-root` so ZFS is tried **exactly once**. A failed ZFS boot
returns to ext4 by itself on the next reboot — no console, no hands. That matters
more here than on a normal host: a hang at an initramfs prompt takes CT 103 down
and the NFS clients hang rather than fail. Only after a second clean ZFS boot
should the saved default move.
### Off-box artifacts (`nh3-dev:~/backups/esh-pve-nas/`)
- `dom-sdq-20260818.img.zst` — full DOM image, 7,837,450,240 B raw / 2.38 GiB
compressed, zstd XXH64 verified. ⚠ **Crash-consistent, not clean** — the root
LV was live during the read, so a restore replays the ext4 journal. Not
fixable with an LVM snapshot: the VG has no free extents.
- `bootchain-20260818.tar.gz` — clean, consistent tar of `/boot` + ESP (88 MB,
644 entries, full proxmox shim/grub EFI chain). This is the higher-quality
boot-chain artifact; the dd image is the belt-and-braces full-device restore.
- `pve-config-snapshot-20260818T051*.tar.gz` — 147 entries incl. the new
grub.cfg, fstab, LVM/ZFS/blkid state.
⚠ Building this the first time produced a **corrupt archive**: `pvs; vgs; lvs >
file` redirects only the last command, so `pvs`/`vgs` output leaked into the
tar stream on stdout. Group with `{ …; } > file`.
Runbook: `docs/runbooks/esh-pve-nas-boot-migration.md`. Earlier config snapshot at
`nh3-dev:~/backups/esh-pve-nas/pve-config-snapshot-20260818T043027Z.tar.gz` (0600,

# Fleet IPv6 state + the real VPN topology (verified 2026-08-17)
Written because the operator expects to reference this "before too long" — the
driver is an **ESH fiber install landing 2026-08-18 that puts the house behind
CGNAT**, which breaks Site Magic on IPv4 and makes IPv6 load-bearing rather than
a nice-to-have.
## Why IPv6 suddenly matters: CGNAT at ESH
New ESH fiber (installing 2026-08-18) hands out a **CGNAT IPv4**. Site Magic —
the UniFi-to-UniFi SD-WAN mesh tunnel that currently links NH3 ↔ ESH — needs a
reachable endpoint, and a CGNAT address is not one. **IPv6 is the escape hatch:
a global v6 address on each UDM restores a routable endpoint pair without
depending on the ISP's v4 at all.** That, not the WireGuard RA mesh, is the
most likely first consumer of fleet IPv6.
Operator expects addresses at **Anaheim shortly** and **ESH 2026-08-18**.
## The topology — as VERIFIED, not as assumed
Three transports, three different technologies. Do not describe this as "a
WireGuard mesh"; a prior session did and was corrected.
| Link | Transport | Evidence |
|---|---|---|
| NH3 UDM ↔ ESH UDM | **Site Magic** (`vpn_type: sdwan-mesh-tunnel`) | UDM `networkconf`, carries all 7 ESH subnets |
| Colo FortiGate ↔ NH3 UDM | **IPsec IKEv2** | FG `pfi-ana-nh3` → 70.230.226.88, **158M pkt rx / 165M tx** — the fleet workhorse |
| Colo FortiGate ↔ ESH UDM | **IPsec IKEv2** | FG `ana-to-eshudm` → 70.181.90.232, 53K/56K pkt |
| Remote-access VPN | **WireGuard, host-based on `ana-wg`** | see below |
**WireGuard is an RA (remote-access) convention only — it is NOT the site mesh.**
It runs on `ana-wg` (LXC 113, Debian 12, 10.250.50.252), interface `wg0`,
**UDP 31337**, tunnel subnet `10.30.10.0/24`, 3 peers (`tc2-mac`, `vh-iphone`,
`vh-mba26`). Reached from outside via a FortiGate VIP `wg-to-ana-wg`:
`38.120.12.42:31337/udp → 10.250.50.252:31337` on wan1.
**The FortiGate never terminates WireGuard — it port-forwards to the host that
does.** FortiOS 7.2.10 has no native WireGuard (Fortinet added it in 7.4), so a
session that reads "colo + WireGuard" and concludes the edge must be upgraded is
chasing a non-problem. Do not re-derive this.
## Per-site IPv6 state (2026-08-17)
| Site | Edge | IPv6 |
|---|---|---|
| **NH3** | UDM SE | **WAN live** — `2600:1700:b25:c110::48` via DHCPv6 on ATTFiber. All 5 LANs `ipv6_interface_type=none` |
| **Anaheim colo** | FortiGate-80F, FortiOS 7.2.10 | **None.** `diagnose ipv6 address list` → only loopback `::1`; every physical iface `ipv6: ::/0` |
| **ESH home** | UDM Pro Max | **None.** Both WANs `wan_type_v6=disabled`; link-local only |
## AT&T delegates exactly ONE /64 at NH3 — proven, not assumed
`2600:1700:b25:c11f::/64`. **One.** Not the /60 the addressing pattern suggests.
The proof matters because the naive read is wrong: the WAN sits at `c110::48`
and the LAN got `c11f::1/64`, which looks exactly like slot 15 of a /60 spanning
`c110`–`c11f`. It isn't. Forcing the prefix ID from auto to a manual `0` — which
on a real /60 would relocate the LAN to `c110::1/64` — left the subnet at
**`c11f::1/64`, stable across a 4-minute settle**. Two different prefix-ID
settings yielding the same /64 is the signature of a single-/64 delegation.
**Consequence: exactly one VLAN can have IPv6 at NH3**, unless AT&T enlarges the
delegation. If Site Magic-over-v6 is the goal that is fine — Site Magic needs a
routable address on the *WAN*, not a LAN prefix.
The controller never exposes the PD size directly (`wan_dhcpv6_pd_size_auto:false`
with no size field alongside), so the prefix-ID test is the only read-only-ish way
to establish it from the API.
## What a v6 mesh actually requires (and what it does NOT)
**Does NOT require prefix delegation.** PD hands addresses to LAN *clients*. Both
Site Magic and WireGuard need a routable address on the router/host WAN side, plus
inbound reachability. Enabling PD on a LAN is orthogonal — this was tested and
then reverted.
**ana-wg's WireGuard socket is ALREADY dual-stack** — `ss` shows both
`0.0.0.0:31337` and `[::]:31337`. It will accept IPv6 peers with **no WireGuard
reconfiguration** once (a) the host holds a routable v6 address (today: link-local
`fe80::be24:11ff:fed7:e4b7` only) and (b) the FortiGate passes inbound UDP 31337
over v6 — the existing VIP is v4-only (`extip 38.120.12.42`).
**NH3 UDM's own WG server is v4-pinned** — `wireguard_interface_binding_mode_ip_version: 'v4'`,
one field to flip when wanted.
**Inbound v6 is default-deny and that held without intervention.** The UDM runs
the **zone-based** firewall (66 policies). ⚠ The legacy `rest/firewallrule`
endpoint returns **0 rules** on this box — a quick check there reads as "no IPv6
rules exist," which is wrong and alarming. Use
`v2/api/site/default/firewall-policies`. WAN→LAN default is `Block All Traffic`
for both families with `Allow Return Traffic`; the only v6-specific allows are
link-local plumbing (ND solicit/advert, RA, DHCPv6).
## The stability problem — design around it up front
All three endpoints will hold **dynamic** addresses (NH3's came via DHCPv6 IA_NA,
not a static assignment). A three-way mesh where every node can move is fragile;
WireGuard tolerates one roaming end, not all of them.
The fleet already solves this on the v4 side — IPsec peers use **hostnames**
(`ana-fw.phasefinal.com`, `nh3.phasefinal.com`), not raw IPs. **Extend that to
AAAA records** and dynamic prefixes stop mattering. infra-ops holds the fleet
Cloudflare DNS-edit token, so this is self-serve.
## Access recipes (cost a prior session real time)
- **UniFi UDMs** — `X-API-KEY` from the vault (`secret get unifi/pfi-udmse-api-key`,
`unifi/esh-udmpm-api-key`) against `https://<ip>/proxy/network/…`, `curl -sk`.
Classic `api/s/default/rest/networkconf` + `stat/device` carry everything here.
Writes are `PUT …/rest/networkconf/<_id>` with the **full** object.
- **`ana-wg` is `root@`, NOT `infra-ops@`** — the shared infra-ops key is refused
(`Permission denied (publickey,password)`). `servers/ana-wg/ssh-target` says
`root@10.250.50.252`; believe it.
- **FortiGate** — paramiko via `uv run --with paramiko` (no sshpass on nh3-dev),
password `secret get fortigate/ana-gw-infra-ops-password`. ⚠ **A fixed-duration
`drain()` hangs the session**; read until the `ana-gw #` prompt and answer
`--More--` with a space. Two invocations timed out at 3 min before this was fixed.
## Changes made and reverted this session
- **Enabled PD on `nh3-iot` (VLAN 90)** to measure the delegation, then **REVERTED
on operator instruction** — all 5 NH3 LANs are back to `ipv6_interface_type=none`,
verified. Pre-change snapshots kept in the session scratchpad only (ephemeral).
- **`ana-wg` WireGuard key material was world-readable** — `wg0.conf` (server
private key + 2 peer PSKs), `keys/*_priv`, `keys/*_psk`, and `configs/*.conf`
(client configs carry private keys) were all mode **644**. Now **600**, and
`keys/` + `configs/` dirs **700**. `wg-quick@wg0` stayed active, 3 peers intact —
WireGuard holds keys in kernel memory, so no restart was needed. The parent
`/etc/wireguard` was already 700, which capped the real exposure to root-capable
contexts inside the LXC — but the modes were still wrong.
---
## CORRECTION (recorded 2026-08-24): "AT&T delegates exactly ONE /64" is the
## per-REQUEST truth, not the total — eight /64s exist and are unclaimed
The section above concludes AT&T hands out a single `/64` and that the
`c110`/`c11f` pattern reading as a `/60` was a misread. **That conclusion was
itself superseded later in the same session, and the correction never made it
into memory** — it survived only in the session transcript, and was recovered
2026-08-24 while assessing a proposal to grab more prefixes.
Reading the **BGW's own LAN statistics page** gave the whole picture:
```
BGW WAN v6 2001:506:70b2:8958::1 <- AT&T's transit prefix
BGW LAN v6 2600:1700:b25:c110::/64 <- the BGW keeps this for itself
Delegated 2600:1700:b25:c11f::/64 <- what the UDM got
```
**The BGW holds the `/60` and rations it**, keeping `c110`–`c117` for itself and
delegating from the top down — the UDM got `c11f`, the last one. So
`c118`–`c11f` are **eight delegatable /64s that genuinely exist and are yours**,
sitting unclaimed.
Both observations are compatible, which is why the first one looked conclusive:
the prefix-ID test only carves *within* a delegation already held, so a UDM
holding one `/64` cannot move it no matter what prefix-ID you set. The BGW
issues **one `/64` per IA_PD request**, and **UniFi solicits exactly once**.
**Consequence — the ceiling is the requester, not the carrier.** More prefixes
need more IA_PD requests (multiple IAIDs, or multiple client DUIDs), which the
UDM will not do. That is what makes a separate DHCPv6-PD client viable, and it
is why "ask AT&T for a bigger delegation" may be aimed at the wrong party: this
looks like BGW rationing rather than a provisioning-profile limit.
Live state at correction time: `wan_dhcpv6_pd_size: 64`, `wan1 v6
2600:1700:b25:c110::48`, all 5 NH3 LANs still `ipv6_interface_type: none`.
### ⛔ CLOSED 2026-08-24 — operator ruling, do not re-raise
The seven unclaimed `/64`s stay unclaimed. Two facts close it:
- **The BGW has no IP-passthrough mode.** Operator confirmed, and we hold admin
on it — so the cheap path (let the UDM take the `/60` directly and carve it
natively, as it already does at ESH) does not exist here.
- **The only remaining route is a multi-DUID DHCPv6 client on a VM**, which
requires re-cabling to reach the BGW's DHCPv6 server, split-stack routing
(UDM for v4, VM for v6), and — the actual cost — **rebuilding the whole IPv6
firewall policy in nftables on that VM**, because routing v6 around the UDM
bypasses its zone firewall entirely and would leave every LAN host globally
reachable.
Operator's call: not worth it. **NH3 LANs stay `ipv6_interface_type: none`.**
Do not re-propose on the strength of "there are seven free prefixes" — the
prefixes are real, the firewall rebuild is why nobody wants them.

# irv-ml1 weight cleanup (782 GB) + Homepage brought under version control
Two unrelated housekeeping jobs from the same session, both with durable lessons.
## irv-ml1 — 782 GB reclaimed
Root was at **92%** (148 G free), storetank **86%**. Now **64%** (635 G free) and
**74%** (477 G).
**Tier 1 — dead weights, 286 GB.** `/storetank/llm-models/Storage` (**217 G**, 22
GGUF repos, atimes Jan–May **2025**) plus `models--MaziyarPanahi--WizardLM-2-8x22B-GGUF`
(44 G) and `models--h2oai--h2ogpt-4096-llama2-13b-chat` (25 G). The 217 G pile had
**zero consumers** — no llama-swap, no llama.cpp, no textgen running *or installed*,
not even a stopped container. The fleet moved to vLLM/NVFP4 seats on ana-ml2 and
nobody opened that shed for 15 months. Re-verified the consumer check immediately
before deleting, not just during the audit.
**Tier 2 — regenerable caches, 194 GB.** `uv` 65 G + 60 G, `pip` 31 G + 8.7 G,
`modelscope` 29 G (mtime **2024-04-23**).
**Tier 3 — retired stacks, 302 GB** (operator: "those were old days… we're a UV
fleet now"): `/opt/fluxgym` 64 G, `/opt/ComfyUI` **native** 41 G, `/opt/stablediffusion`
28 G, `/opt/alltalk` 19 G, `/opt/o-textgen` 12 G, `/opt/sdnext` 3 G, `/opt/xttsv2`
1.8 G, `tabbyAPI` 3.1 G, **`miniconda3` 130 G**.
### The lesson: one dead-looking app pinned three delete targets
`lsof +D` per path found **PID 281192 — fluxgym, up 42 days, listening on
0.0.0.0:7860** — holding 15 open handles into `miniconda3/envs/vllm` (stale
opencv wheels) **and 41 into `/opt/ComfyUI`**. Deleting miniconda underneath it
would have half-broken a live listener in a way that surfaces only at its next
restart. Stopped it by **explicit PID** (never `pkill -f` — handle-blind),
verified :7860 released and handles at zero, *then* deleted.
⚠ **Name collision that nearly cost a production service:** `/opt/ComfyUI` is a
*native* install; the ComfyUI that actually serves (:8188, 200 OK) is the **Docker
`mmartial` container** reading `/worktank/comfyui`, and arbo's `comfy_engine` runs
from uv. Checking open handles **per path** is what separated them — the earlier
"not running" read would have deleted the wrong thing.
⚠ **`df` lags an async ZFS free.** Right after the 217 G delete, storetank still
showed 86%/261 G — the exact shape of a snapshot-retention problem. It wasn't
(`zfs list -t snapshot` empty); second check showed 477 G at 74%.
All 16 containers and both systemd services verified healthy afterward.
## Homepage under version control
`ghcr.io/gethomepage/homepage` on **esh-docker-vm:5100** was the one stack whose
config lived only on the host. Its version history was **six hand-rolled
`services.yaml.bak-*` files**. Now `stacks/homepage/` (compose + 9 config files +
`.env.example` + README), deployed via `deploy-stack.sh`; `.bak` files gone.
105 cards across 19 groups, no empty groups.
⚠ **I claimed ana-docker wasn't wired into `docker.yaml`. It already was** —
`ana-pfi-docker: 10.250.50.70` — and I built a theory on a `tail` that truncated
the top of the file. All five engines were discovering correctly the whole time.
**Corrections landed:** `ANA-Firewall` said "Fortigate 81F" → it is a
**FortiGate-80F, FortiOS 7.2.10** (verified against the device); `NH3-Ansible` →
**NH3-ExtDev** (10.100.50.42 is nh3-extdev, successor to the retired nh3-ansible);
dropped the `UltraSeedbox` layout group (nothing provides it).
⚠ **`HOMEPAGE_ALLOWED_HOSTS` matches host AND port.** `10.0.50.45` did **not**
cover `http://10.0.50.45:5100/` — the container log carried `Host validation
failed` while the Traefik hostnames worked. Fixed; direct IP:port now 200.
`.env` was **mode 644** holding Plex + Jellyfin API keys → now 600.
⚠ **Homepage renders client-side** — grepping the served HTML to verify a config
change gave two false readings (a stale prerender, then an empty page).
`GET /api/services` is the honest instrument, and config changes need a
**recreate**, not a restart (a restart keeps the cached render in the writable
layer).
⚠ `deploy-stack.sh` runs rsync with `--delete` — alongside the six `.bak` files it
also removed a host-side `README.md` in the conf dir. Content survived (it is now
in the repo README) but that was a side effect, not a plan.
Commits `c5beeac`, `d1f4f1c`. See also [[2026-08-17-fleet-ipv6-mesh]].

# `[2026-08-19]` esh-pve hard-froze for 4.5h — and took the whole house's DNS with it
Reported by the operator as "routing or DNS issues on the PVC wifi." It was
neither: the internet was healthy the entire time (gateway reporting 3 ms and
209/26 Mbps; 1.1.1.1 and 8.8.8.8 answering at ~3 ms from inside ESH with zero
loss). **The house had no name resolution because one VM was down.**
## The SPOF: one resolver, cross-VLAN, no fallback
`esh-userland` (VLAN 10, `10.0.10.0/24` — the `PVC` SSID *and* the wired
userland LAN) handed out **exactly one DNS server, `10.0.50.45`** — AdGuard, on
`esh-docker-vm`, on the **server** VLAN. No secondary. That VM dies, every
client on the VLAN loses DNS, and it presents as "the wifi is broken."
It was the only network in the house exposed this way. `Default`, `esh-mgmt`,
`esh-server` and `esh-cameras` run DNS on auto (the gateway hands itself out);
`esh-iot` and `ESH-WG` point at 1.1.1.1 + 8.8.8.8.
**Fixed** (operator-approved): `esh-userland` now hands out `10.0.50.45`
primary, **`10.0.10.1` (the gateway) secondary** — the UDM's own resolver,
verified answering. Applied via the Classic API,
`PUT /proxy/network/api/s/default/rest/networkconf/687985eae5d15b673cef1a73`
with the full object (GET → modify one field → PUT), `rc: ok`. **This was also
the first confirmed WRITE on the ESH UDM key** — previously only the NH3 key
was write-tested. See [[reference_unifi_udm_integration_api_keys]].
⚠️ **A secondary is not clean failover.** macOS/iOS query resolvers in
parallel, so once AdGuard is back a real share of lookups go to the gateway and
**skip ad-blocking**. This converts a total outage into degraded-but-working.
The actual fix for blocking integrity is a second AdGuard instance NOT on
esh-pve.
## Root cause: hard freeze, no diagnostics, two suspects
`esh-pve` (Minisforum MS-01, i9-13900H, `productname: YajuuSenpai`) froze at
**03:34:39**. The journal stops mid-operation — **no panic, no OOM, no MCE, no
thermal event**. Powered on with its 10G link up, but not answering ARP.
Two changes landed the day before, and they are not exclusive:
1. **New kernel.** A large `apt` batch on **2026-08-18 07:00:21** installed
`proxmox-kernel-6.8.12-42-pve`; clean reboot at 07:08:44. Before that the
box had **4.5 months of uptime** (Mar 30 → Aug 18) on `6.8.12-16`. First
boot on the new kernel lasted **20 hours**.
2. **GPU passthrough.** The last kernel messages of the dead boot are
`vfio-pci 0000:01:00.0/.1: enabling device` at **02:55:17** — VM 102
`esh-vm-workstation` starting with `hostpci0: 0000:01:00,pcie=1,x-vga=1`,
**39 minutes before the freeze**.
A vfio/i915 regression in the newer kernel would produce exactly this
signature. `6.8.12-16` is still installed and is the held-in-reserve rollback.
**VM 102 is now pinned off** (`qm set 102 --onboot 0`, stopped) per the
operator — it is on-demand and there has been no demand. That removes the
suspect without a kernel rollback.
## Why nobody could recover it remotely — and the fix
Nothing on the box could reboot it:
- **`softdog` was the loaded watchdog.** A *software* watchdog cannot rescue a
hard kernel freeze: the frozen kernel is the thing that would have to fire
its timer. This is the trap — the machine *looked* watchdog-protected.
- **Proxmox's `watchdog-mux` held `/dev/watchdog` but never armed it.** It only
pets the device while an HA client is connected, and this cluster has no HA
resources.
- **vPro/AMT was unusable.** The MS-01 reaches the network only via **SFP+**
(Intel X710, port 27 on the Garage switch) and presents exactly one MAC.
**AMT cannot ride a discrete/SFP+ NIC** — it needs the chipset-integrated
Intel PHY, i.e. one of the two i226 RJ45 ports, and both are unplugged.
Cabling one and provisioning AMT in MEBx remains the open item for *control*;
the watchdog below is the fix for *recovery*.
**Fixed:** `playbooks/esh-pve-hardware-watchdog.yaml` — systemd now owns the
PCH hardware watchdog (`iTCO_wdt`, `RuntimeWatchdogSec=60`), `softdog` is
blacklisted and unloaded, `watchdog-mux` is masked. Verified live:
`watchdog0: identity=iTCO_wdt state=active timeout=60s`, held by PID 1,
journal `Using hardware watchdog 'iTCO_wdt', version 6`. Playbook re-run proves
idempotency (6 skipped / 6 verify OK).
Firmware does **not** block the TCO timer here — checked for the
`unable to reset NO_REBOOT flag` line before committing to the approach; the
board reports `Found a Intel PCH TCO device (Version=6, TCOBASE=0x0400)`.
⚠️ **Masking `watchdog-mux` trades away HA fencing.** If Proxmox HA is ever
configured on esh-pve this must be reverted. Not a near-term concern:
`esh-pve-cluster` is **two nodes with no qdevice**, so a single node loss
already costs quorum and the survivor would fence itself — HA here would reduce
availability, not raise it.
⚠️ **The watchdog is configured and armed, but has NOT been proven to fire.**
Proving it means deliberately wedging the host. Untested-but-armed is still
strictly better than softdog; treat a real firing as unconfirmed until tested.
## Diagnostic corrections worth keeping
- **"No route to host" was the dead host, not a routing gap.** Two claims made
mid-incident were wrong: that the mgmt VLAN (`10.0.250.0/24`) is not routed
over the NH3↔ESH tunnel, and that a firewall isolates it from the server
VLAN. Both were artifacts of esh-pve being dead. With it up, `root@esh-pve`
SSHes fine from nh3-dev at 7.5 ms, and `10.0.250.1` answers from
`esh-pve-nas` in 0.078 ms. **Control-test against a *different* host on the
target subnet before concluding "the subnet is unreachable."**
- **UDM `uptime` on a client record is association time, not host uptime.** It
read 2.2 days while the host had been up 20 hours. Use
`journalctl --list-boots` on the host for real boot history.
- **`rest/user` `last_seen` is not maintained** (it read ~203 days for hosts
that are demonstrably online). `stat/sta` is the live view.

# `[2026-08-19]` Fleet `.internal` DNS — git-sourced, agent-managed, three resolvers
Operator: *"with ipv6 i can't memorize the IP addresses anymore. need a way to
keep track of local .internal dns names that can be agent managed and is
lightweight."* Built and live in one session; commit `b8003c7`.
## Shape
```
dns/internal.yaml source of truth — 38 hosts + 4 service aliases
scripts/dns-sync.py reconciles AdGuard resolvers against it
stacks/adguard-ana/ the colo's resolver, which did not exist
dns/README.md workflow, naming, the IPv6 caveat
```
Deliberately the same posture as `deploy-stack.sh`: the file is intent, the
resolvers are derived state, you see a diff before anything changes.
`--dry-run` / `--yes` / `--site <s>`. Verified idempotent — a second run prints
`nothing to do`.
Naming is `<host>.<site>.internal` with sites **`ana` / `esh` / `nh3`**
(operator's call). `.internal` is ICANN-reserved for private use since 2024;
`.local` is reserved for mDNS, which is why the pre-existing
`searxng.pfi.local` was a standards collision that merely happened to work.
Every name is published to **every** resolver — the site label says where a
host *is*, not which resolver knows about it.
## The framing correction that mattered most
The ask reads as "I can't memorise v6 addresses", but the deeper problem is
that **v6 addresses are derived, not assigned**, so they cannot reliably be
*written down once* either. SLAAC gives EUI-64 (MAC-coupled) or
privacy-extension (rotating) addresses, and UniFi has **no v6 equivalent of a
DHCP reservation** — so a hand-maintained v6 table rots on its own.
⇒ The fix has two halves and only the second is DNS: (1) pin static v6 on
server-class hosts, (2) then the name table is just a file. Surfaced to the
operator before building.
**Verified 2026-08-19: no fleet host has a global v6 address at all yet** —
ESH's `/56` is live only on `esh-cameras`, NH3's LANs are back to
`ipv6_interface_type: none`, the colo has none. So the `v6:` column ships
EMPTY and correct, and the naming layer was built first rather than blocking
on v6. Names established now need no renaming when addresses land.
Suggested convention when they do (awaiting operator): each server static at
its site's `/64` with low-order bits echoing the v4 host octet —
`esh-docker-vm` at `…::45` — so addresses are declarable *and* semi-memorable.
## Two properties not to break
**Authority is scoped to the ZONE, not the resolver.** Only rewrites ending in
`.internal` are managed. ESH's resolver turned out to carry three hand-made
`esteban.net` rewrites (`eshnas`, `brotherprinter`, `eshhome`) — **my first
read of the config missed them**, because an `awk` range on `rewrites:` matched
an empty-looking block. A resolver-wide authoritative sync would have silently
deleted all three on first run. Verified intact after sync.
**Within `.internal` it IS authoritative** — names added by hand in the AdGuard
UI get deleted by the next sync. That is the point: one place to look.
## The colo had no resolver at all
ESH and NH3 each ran AdGuard; **ana-docker resolved straight against
`1.1.1.1`**, so the colo had no way to answer for internal names. Closed with
`stacks/adguard-ana/`.
⚠️ Its API is on **8053**, not 8080 — `:8080` and `:3000` were already taken on
that busy host. The port is therefore carried **per-site in the yaml**, not
assumed by the script, so the odd one out cannot be forgotten.
⚠️ It ships with **no blocklists**, deliberately. The other two filter ads for
human browsing; this one resolves for a rack of servers, where a blocklist
false-positive breaks service-to-service calls at 3am for no upside.
First boot uses a **seed config** (`conf/AdGuardHome.seed.yaml`) copied into
the conf volume before first start, so the container comes up configured
instead of sitting in the setup wizard.
## Credential — service account, not the operator's
Added a dedicated **`infra-ops`** AdGuard user to all three resolvers rather
than asking for the `lkraven` password (per the standing migrate-off-operator-
creds directive). Password vaulted at
`nh3-dev/adguard-infra-ops-password`; `lkraven` untouched; pre-change configs
backed up on each host as `AdGuardHome.yaml.bak-preinfraops-*`. Both existing
resolvers kept answering across the restart.
Two landmines worth keeping:
- **Go's bcrypt rejects `htpasswd`'s `$2y$` prefix.** Same algorithm, different
marker; `golang.org/x/crypto/bcrypt` accepts only `$2a$`/`$2b$`. Normalise
the prefix, and self-verify the hash with `htpasswd -vb` BEFORE installing it
on a live resolver.
- **The vault appends a trailing newline on `get`.** A password carrying a
stray `\n` fails auth in a way that looks exactly like a wrong password.
`dns-sync.py` strips it.
## `pfi.local` migration — and the one that must NOT move
`searxng.pfi.local` → `searxng.ana.internal`, with the **old `Host()` kept
alongside** in the Traefik rule so nothing breaks mid-migration; both return
200. Drop the fallback once the access log shows the old name unused.
**`matrix.pfi.local` deliberately NOT migrated.** A Matrix `server_name` is
baked into every user ID, room ID and signing key, and federation identity
derives from it — renaming it is not a DNS change, it is rebuilding the
homeserver's identity and invalidating its history. The operator approved
"migrate pfi.local" generally; this was surfaced as a deliberate exclusion
rather than executed blindly.
## Still open
Colo hosts still point at `1.1.1.1`, so they do not yet *use* the new resolver
— it only answers what asks it directly. Repointing a whole site's DNS is a
bigger change than standing the service up, and is the operator's to schedule.

# `[2026-08-19]` Homepage cleaned up, then themed with Australis Skyfall + an Arbo-generated background
Commits `9d92c4b`, `c3de7db`, `45c1995`, `f38cf69`, `df68dd2`.
## The cleanup (three real defects)
- **UltraSeedbox rendered on all four tabs.** The bookmark group had no entry in
`settings.yaml`'s `layout:` block at all, and Homepage's documented behaviour
is that a group with no `tab:` is shown on **every** tab. Pinned to Main.
⚠️ This will happen again to the next group added without a `tab:` — the rule
is now written at the top of the layout block.
- **Uptime Kuma rendered twice** — a manual `services.yaml` entry under
Monitoring *and* `homepage.group=Apps` on the container. Exactly the
"never list a labelled container manually" failure the stack README warns
about; it survived the previous day's audit because a duplicate reads as two
plausible cards rather than as an error. Manual block deleted, label moved to
`Monitoring`, `homepage.siteMonitor` added.
- **Column counts were fiction** — several groups declared more columns than
they had members, so the last row of each was dead space (Notes: 1 card in a
4-wide row). Columns now track member counts; `GET /api/services` prints the
live per-group counts and is the check.
Later, on operator instruction, the **AI tab was reordered by clickability**:
Gateways & Chat → Image & Media → Audio Tools on top, then the vLLM `/docs`
seats and TTS endpoints. Reasoning written into the config so it survives:
order by "would I click this?", not by how central the service is.
## ⚠️ The expensive red herring — the tab bar after a recreate
After a recreate the client render comes up with **no tab bar, no wallpaper and
no i18n** (search box shows the raw key `search.search`), groups falling back to
side-by-side columns. **It restores itself with no intervention.**
Timing, measured rather than assumed: a fresh container was still tab-less at
**4m30s, twice**; it was healthy again after roughly an hour. `docker ps`
reporting `healthy` says nothing about it — the container is serving, the page
is just wrong.
An hour went into ruling out four causes that were never the cause:
1. **Not the config** — restoring `settings.yaml` *and* `services.yaml` to
their committed versions reproduces it, as does the pre-adoption backup in
`/opt/docker-bu/conf/homepage/`.
2. **Not the v2.0.0 release** — a throwaway container on `v1.13.2` shows
identical symptoms, and the image never changed anyway (working and broken
both report `v2.0.0` / rev `17456f2`).
3. **Not `PUID`/`PGID`**, and not Docker discovery — tested both, and with the
socket unmounted entirely.
4. **Not server-side** — the server-rendered HTML still contains the tab
markup, the background URL and `useEqualHeights`; `GET /api/validate`
returns `[]`. The loss is client-side, with no page error, no failed chunk
and no non-200.
Every throwaway container in that list was judged within ~30s of starting, so
they were all inside the same window — and that consistency **read as a
reproduction when it was the same measurement mistake five times over.**
**Operative rule: recreate, walk away, re-check later. Do not chase it.**
## ⚠️ The iteration loop that would have prevented the overcook
`custom.css` is served **per request** from `/api/config/custom.css`, so a CSS
change needs a **browser reload** — not a container recreate, and it never owed
the layout warm-up above. Conflating the two costs ~10 operator-visible minutes
per attempt (operator called this out directly).
Faster still, and how the final pass was done: **inject candidate CSS into the
running page and screenshot it** —
`await p.addStyleTag({content: css})` in Playwright against the live
dashboard. Seconds per iteration, no deploy. Build + deploy only once the
render looks right.
## The theme — Australis Skyfall
Operator supplied a Claude Design handoff bundle via the Booth (`26-copper`).
Skyfall is a dual-theme OKLCH system: one lightness law across every chromatic
family (deep 0.48 / base 0.66 / bright 0.80), all hues cooler than neutral, a
Sea neutral ramp drifting ice-blue→ocean-green as it brightens, and a
"calm depth" language of **hairline + two-layer shadow on every elevated
surface, never one without the other**.
```
theme/colors.css layout.css typography.css vendored VERBATIM from the bundle
theme/fonts/Supreme-{400,500,700}.woff2 the body/UI face
theme/skyfall.css.in the Homepage bindings (ours)
theme/build.py → conf/custom.css (generated — do not hand-edit)
```
The build step exists for one reason: **Homepage serves only `custom.css` and
`custom.js` out of its config dir**, with no static route beside them, so a
`@font-face` pointing at a vendored `.woff2` would 404 — the face must arrive
as a data URI. The background image takes the other road, because
`/app/public/images` **is** a real static route (mounted read-only in
`compose.yaml`).
Only Supreme is embedded: a link dashboard has no display type, and Victor
Mono ships as 2.4 MB TTF statics per cut — 30x the whole stylesheet for a
handful of latency figures.
## The background is generated, not stock
**Arbo as an image-gen engine** (the operator's actual ask, which I first
misread as "use Arbo's palette" and had to redo). Arbo's `t2i-ui-background`
workflow is purpose-built: *"abstract full-bleed backgrounds, no subject"*.
Job `13f0891f4e42`, seed 26, flux2-klein-9b, 2048×1152, 1.6 MB PNG → **22 KB
WebP** (smooth gradients compress absurdly well).
⚠️ Arbo API gotcha: `prompt` is a **discriminated union, not a string** — a
bare string 422s. `{"kind":"raw","text":…,"negative":…}` is the shape.
## Two documented deviations from the design system
1. **Skyfall forbids this background.** Its rule is "flat semantic surfaces; no
photography, no textures", with one permitted motif — a subtle aurora
gradient on hero/empty-state areas only, *"never behind body text blocks"*.
A dashboard is a body-text block. Present on the operator's explicit
instruction, mitigated rather than excused: abstract, no subject, strictly
cool temperature, held at **`opacity: 30`**. That number is load-bearing —
at 14 the aurora was invisible, and turning it up makes the cards fight the
ribbon.
2. **Service icons stay full-colour vendor logos.** Desaturating them from CSS
only makes them illegible.
## Overcorrection, and the colour pass
First stat-well pass went from `font-thin` 13px straight to **bold 22px in
heading white** — operator: *"went from subtle to BASH YOU OVER THE HEAD."*
The principle missed: a stat only has to out-rank **its own label**, not the
service name above it. Now `--text-md` medium in cyan.
Colour was then lifted **from inside the system**: Skyfall names Aurora (blue,
cyan, green) the *primary* families, "used generously, in that order", while
Dawn (amber/red/violet) is semantic-only. So group markers cycle
blue→cyan→green down the page (icons full strength, names at 0.72), service
icons take a single cool wash, latency tags move to the info family so
"how fast" stops looking like "is it alive". **No Dawn colour is used
decoratively anywhere.**
Two DOM findings that made it possible:
- **Homepage renders mdi icons as a gradient behind an SVG mask** — recolour
via `background`, not `color`.
- **Homepage emits `docker-status-<state>`, not `status-<state>`.** The
original selectors matched nothing, so every green pill up to that point was
stock colouring rather than the theme. Both forms are now matched.

# `[2026-08-19]` Four unmanaged stacks found on live hosts — and two of them were quietly broken
Commits `42c594c`, `dc3e47b`, plus `uptimekuma` in `9d92c4b`.
## The pattern worth remembering
Chasing two bad-looking cards on the dashboard turned up **four stacks running
on fleet hosts with no canonical copy anywhere**: `uptimekuma` and (already
known) the two AdGuards on esh-docker-vm, `searxng` and `seafile` on
ana-docker, and `heretic2-charrp-reasoning` on ana-ml2 (untracked in git).
⇒ **A dashboard card is a cheap census of what is actually running.** When
something on it looks wrong, check whether the stack behind it is even in
`stacks/` before debugging the symptom — twice here the answer was "no", and
the fix belonged in version control as much as on the host.
Adopted: `stacks/uptimekuma/`, `stacks/searxng/`, `stacks/seafile/`,
`stacks/heretic2-charrp-reasoning/`. ESH/NH3 AdGuard compose files were
**deliberately left unmanaged** — adopting three live resolvers while also
introducing a new DNS naming system is two risky changes at once.
## SearXNG — the healthcheck was eating itself
Card flapped UNHEALTHY; the container was fine the whole time. The compose
passed `--tries` and `--spider` as **two separate argv entries**, so wget
consumed `--spider` as the *value* of `--tries`. Spider mode never engaged,
which means every probe since April **downloaded** the healthz response to a
file:
```
295,287 healthz.N files in the container's working directory
```
With that many files, wget's scan for the next free filename is what
intermittently blew the 10s timeout. **Self-worsening — every probe made the
next one slower.** Restored `--tries=1`; the junk lived in the writable layer
so the recreate cleared it. Now `healthy`, `fails=0`, 200 in 0.16s.
Lesson: an argv list in YAML has no shell to catch a missing `=`. A flag that
silently swallows the next argument turns a liveness probe into a workload.
## SeaFile — not broken, never restarted
Card showed EXITED for three months. **None of the three services declared a
restart policy**, so Docker defaulted them to `no`. On
**2026-05-06T21:27:45Z** the daemon stopped all three within 200ms of each
other — a daemon restart or host reboot — and nothing brought them back.
⚠️ **Exit code `255` is a red herring**: it is what a container that ignores
SIGTERM reports when the daemon stops it, **not** evidence of a crash. Reading
it as one sends you hunting a bug that does not exist. The tell was all three
services stopping within 200ms.
Added `restart: unless-stopped` to all three; brought up; mariadb gated on its
healthcheck exactly as the existing `depends_on` comments intended, seahub
started without the race, `302` → login page. Data was in local named volumes,
not on the ana-nas NFS, so nothing was at risk.
Three months of silent downtime whose only signal was a card nobody read as an
outage — the argument for semantic status colour on the dashboard (see
[[2026-08-19-homepage-skyfall-theme]], where amber EXITED pills made six
mis-grouped AI seats obvious at a glance).
## heretic2-charrp-reasoning — tracked, with its shim
The `char-rp-reasoning` seat (NEO-CODE Heretic2 27B, modelopt NVFP4 + grafted
BF16 MTP head, ~77 tok/s via `qwen3_5_mtp` spec-decode) had been running
untracked. Now in `stacks/`, including
`conf/mtp-workaround/sitecustomize.py`, which is **not optional**: vLLM 0.24.0
does not propagate modelopt `exclude_modules` to the spec-decode **draft**
model, so the BF16 MTP head gets quantized and the engine dies at load. Both
the mount and `PYTHONPATH` are load-bearing.
Added the two files house convention expects and the directory lacked — a
`.env.example` naming every knob (all values are compose defaults; the host
overrides only the three VRAM ones) and a README pointing at
`docs/runbooks/heretic2-nvfp4-mtp-seat.md` rather than duplicating it.

# `[2026-08-19]` waterland studio containerised on irv-ml1 — three landmines, all measured
Handover from `waterland-dev` over althing (thread `01M0CDRGEZWAJCEJXXMQWXV80F`):
a FastAPI + SPA GPU service fronting the `waterland` CLI, running as a bare
`nohup` (PID 1283383) that would not survive a reboot. Now
`stacks/waterland-studio/`, `restart: unless-stopped`, healthy on
irv-ml1:8410. Commits `a2b5b58`, `8189076`.
Tracking `main` per operator: PR #4 merged and `main` HEAD was exactly the
pinned `8025366`, so tracking-a-moving-ref and keeping-the-pin agreed anyway.
**Now deployed at `b72425b` (2026-08-19).** The container sat on `8025366` for
a few hours after PR #5 (`464dfc2`) landed — deliberately, since the image's
own guards already neutralised both landmines and the project was in
wind-down. PR #6 (the job-store rehydrate, operator-green-lit) was the rebuild
with a real reason behind it, and one `update.sh` run carried both. Verified
end to end after the update: healthy, `backend: cupy`, and a real 256² plate
render completes warm — the kernel-cache volume survived the image swap.
## Build context lives OUTSIDE the compose dir — on purpose
`/opt/waterland-studio/src` is the checkout; the Dockerfile is passed
out-of-context from `/opt/docker/compose/waterland-studio/`. **`deploy-stack.sh`
rsyncs `stacks/<stack>/` with `--delete`**, so a checkout kept beside
`compose.yaml` would be destroyed by the next deploy of this stack. `update.sh`
refreshes source → rebuild → recreate → health, and is verified end to end.
## Landmine 1 — both uv extras are load-bearing at BUILD *and* RUN
`gpu` carries `cupy-cuda12x`; a bare `uv sync` prunes it and the renderer
silently drops to the numpy path at ~21x wall time — it does not error, it
just gets slow. waterland-dev warned about the build side.
The runtime side is worse and was not in the handover: **`studio/jobs.py`
shells the renderer out as a literal `uv run waterland ...` with no `--extra`
flags** (`cwd=WATERLAND_STUDIO_REPO`). Left alone, uv re-syncs the project
mid-job to its default extras and prunes cupy back out from under a correctly
built venv. Pinned with `UV_NO_SYNC=1`; `UV_OFFLINE=1` alongside so that if the
pin ever stops holding the job fails **loudly** instead of quietly rebuilding a
slower environment.
**Fixed upstream in `464dfc2`:** the server now spawns
`sys.executable -m waterland.cli` directly — no resolver in the render path at
all. **The pins stay anyway.** They cost nothing and are now defence-in-depth:
if any future code path re-enters `uv` inside the container, the job fails
loudly instead of quietly dropping to the numpy backend. `uv` itself must stay
in the image regardless — it performs the build-time `uv sync` /
`uv pip install`, and this is a single-stage build.
## Landmine 2 — cupy needs CUDA HEADERS, which the host never had to declare
Every render died 1.7s in with:
```
RuntimeError: Failed to find CUDA headers.
```
printed **through argparse's usage banner**, which makes it read like a CLI
argument bug rather than a missing toolkit. That misdirection is the reason
this is written down.
cupy compiles kernels at runtime through NVRTC, which needs the toolkit
**headers** — not just the driver and the runtime libs bundled in the
`cupy-cuda12x` wheel. irv-ml1 has a CUDA toolkit installed system-wide, so the
bare `nohup` process found them **by accident**; a slim image has none.
Fixed with `uv pip install "cupy-cuda12x[ctk]"` — headers as wheels, a few
hundred MB against ~6 GB for a `-devel` base image. It runs **after**
`uv sync`, because sync prunes what it does not know about.
Reported upstream: it is an undeclared runtime dependency of the `gpu` extra,
and anyone running this without a system toolkit hits it. **Declared upstream
in `464dfc2`** (`gpu` is now `cupy-cuda12x[ctk]>=13`). **The explicit install
stays in the Dockerfile**: the header requirement is a property of *this*
image — a slim base with no system CUDA toolkit — so it belongs in the file
that creates the problem, not inherited from an extra two repos away. It also
survives any future restructuring of the `gpu` extra. Cost of keeping it is
now measured, not assumed: since `uv sync` satisfies it first, the line
reports `Audited 1 package in 49ms` and adds **0.3s** to the build. A no-op
that documents a non-obvious requirement is worth 0.3s. (waterland-dev
independently agreed they would keep it too.)
## Landmine 3 — the GPU index inside the container is not the host's
The app pins `CUDA_DEVICE_ORDER=PCI_BUS_ID` and selects
`CUDA_VISIBLE_DEVICES_TARGET` (default `1`, correct on the host, where
`nvidia-smi` shows A6000 at 1). Compose exposes **exactly one** GPU
(`device_ids: ["1"]`, the A6000 in Docker's ordering), so **inside** the
container that card is index **0** ⇒ `CUDA_VISIBLE_DEVICES_TARGET=0`. Copying
the host's value selects a device that does not exist. Host device 0 is the
3090, which carries the TTS zoo and must not be touched.
## Cold start is ~17s of NVRTC compile → `/root/.cupy` is a volume
| job | wall |
|---|---|
| 256² + anim, cold container | 23.3 s |
| 256² + anim, warm | **6.1 s** |
| 256² plate only (`--codec none`) | 3.9 s |
| 512² plate only | 6.4 s |
Warm beats the **7.4 s** recorded against the bare-metal process, so
containerising cost nothing. Verified the cache volume properly: recreate
(fresh cache → 23.2 s first render) then restart (populated → 6.0 s). Without
it every restart makes the next user wait 4x and the service merely *looks*
slow.
## Upstream finding — the on-disk job store grows without bound
`JobStore._jobs` is a plain dict and **nothing scans `WATERLAND_STUDIO_DATA` at
startup**. Consequences:
1. After a restart `/api/jobs` lists only jobs created since — cosmetic, and
how this was spotted: the API reported **1 job** while the volume held all
**16 directories, 60.6 MB**. Not data loss.
2. The real one: `RETAIN = 40` eviction only ever iterates the in-memory dict,
so directories orphaned by a restart are **never reclaimed**. The
handover's "bounded around 500 MB" holds within a single process lifetime;
across restarts the store grows monotonically at ~12 MB per animated job.
Reported to waterland-dev with evidence; **not patched from the infra side** —
it is their code. Prune the volume by hand if it bites first.
**waterland-dev confirmed it (2026-08-19)** — their "bounded ~500 MB" handover
claim holds within one process lifetime and nowhere else, which on a
`restart: unless-stopped` service is the wrong lifetime to have bounded. They
have **surfaced a startup-rehydrate fix to the operator** rather than opening a
third PR during wind-down. **Operator green-lit it; PR #6 merged as `b72425b`
and is DEPLOYED (2026-08-19).**
Startup rehydrate, as recommended — and waterland-dev deliberately went
further than the framing I sent them. I had said a directory the scan cannot
parse "just does not enter the index"; they made the opposite call, because a
directory that never enters the index is exactly the one that never gets
reclaimed. **That is the sharper reading and it is the reason the fix works on
this volume at all** — the 16 pre-existing dirs have no sidecar. Their
adoption ladder: sidecar → restored verbatim; no sidecar → adopted with
dimensions recovered from the PNG IHDR (24-byte read, not a decode); corrupt
sidecar → degrades to inference, no startup crash; **neither source nor
sidecar → skipped on purpose**, since adopting it would turn eviction into a
delete-arbitrary-directories primitive pointed at this volume. Sidecar writes
go through `os.replace`, and `job.json` is excluded from `ARTIFACTS` so it is
unreachable via the artifact route.
They also closed a second leak I never saw, because it needs a restart
*mid-render* to surface: a job left `running`/`queued` in its sidecar is
non-terminal forever, and eviction skips non-terminal jobs — so it is a
phantom that is never reclaimed and `queue_depth` over-reports for the life of
the process. Adoption now marks those `failed`.
**Verified on this host after the update:** `/api/jobs` went **1 → 16** while
the volume stayed at 16 dirs / 61 MB — disk and API agree for the first time.
Nothing was reclaimed, correctly: 16 is under `RETAIN=40`, so adoption only
made them visible. A subsequent real render took both to 17. From here the
store is bounded **across** restarts, not merely within a process.
## Access
Repo is not anonymously readable (a bare clone 403s). Operator granted
**`claude-bot` read on `vh/waterland`** — verified `admin: False, push: False,
pull: True`. Token on irv-ml1 at
`/root/.config/waterland-studio/git-credentials`, `0600` root-owned, wired as a
**repo-scoped** credential helper; `.git/config` carries no token (verified),
so the remote stays clean in any diff or backup. The operator's `vh`
site-admin token was used only for the initial clone and the grant itself and
was **never written to disk on that host** — a site-admin credential on a GPU
box is a blast radius nobody needs for a read-only fetch.
## Constraints honoured as stated (not inferred)
- **Serial by design — one replica, one card.** A render is 20–45s of near-full
GPU with a single worker thread. Two on the same A6000 would OOM or thrash.
Throughput is a hardware conversation, not a replica-count one.
- **No authentication, arbitrary file uploads** ⇒ stays inside the
LAN/WireGuard boundary. Do **not** paper over it with a proxy password;
waterland-dev offered to add a real auth layer if wider reach is ever needed.

# `[2026-08-20]` Cold-Fusion abliteration — Robinson recipe captured, and the transformers/DeltaNet bf16-NaN fight
The real work of the session: abliterate `DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1`
using the MTP-aware, vision-preserving **Robinson formula** (documented in
`docs/pfi/abliteration-recipe-qwen38.md` from `RobinsonLabs/Qwen3.8-27B-abliterated`).
Harness: `services/coldfusion-abliteration/`. Runs on ana-ml2.
## Why this model, why abliterate it ourselves
Stock Cold-Fusion's refusal profile was **probed 2026-08-19** (Q6_K GGUF on
llama.cpp, 24-prompt battery, hand-verified after a keyword-classifier bug):
**~33% creative refusal**, concentrated on **explicit-sexual + graphic-torture**;
4/5 hard-harm technical refused; self-harm guardrails intact 3/3; benign
over-refusal 0. So there is a real creative-content refusal surface to remove.
This **supersedes** the earlier "watch for DavidAU's own heretic build" posture —
we abliterate it ourselves.
**It is additive over the current gen seat.** The live Heretic seat
(`qwen38-27b-heresy-bf16`) left its MTP head a **byte-identical base graft** —
the `Qwen3_5ForConditionalGeneration` wrapper never loads it, so Heretic could
not touch it. The Robinson formula abliterates the MTP head **in-band** (its 2
residual-write matrices), and the MTP head is what gates speculative acceptance.
That in-band MTP edit is the delta this experiment tests.
## Recipe maps 1:1 — dry-run PASSED
Against the staged bf16: 1199 tensors, 333 vision preserved,
`down_proj=64 o_proj=16 linear_out=48 mtp=2 embed=1`, coverage gate 6/6, exactly
**131** tensors to orthogonalize. Same architecture as RobinsonLabs' base, no
name drift. Two hard gates in the harness halt before any write: the coverage
identity `o_proj(16)+linear_out(48)==64`, and the attention-sink screen on
**dim 3994** (orthogonalizing a direction living there bricks the model).
## Capture SUCCEEDED — but only after a real environment fight (the durable lessons)
**The transformers Qwen3.5 DeltaNet linear-attention NaNs in bf16 on ana-ml2.**
The fast-path needs BOTH `flash-linear-attention` (`fla`, triton, installs fine)
AND `causal-conv1d` (**needs nvcc to build — absent, no prebuilt wheel**).
Without causal-conv1d the DeltaNet short-conv runs the torch fallback, which
produces **nondeterministic all-NaN** hidden states in bf16 (same 11-token input:
finite on one forward, NaN at layer 4 on the next). bf16 and fp32 share exponent
range, so this is **precision-driven catastrophic cancellation, not overflow** —
**fp32 resolves it.** Diagnosed via `diag_nan.py` / `diag2.py`: `sdpa` + plain
prompt = 65 layers all finite; chat-template input = NaN; the trigger is the
input path through the unstable recurrence.
Fixes, all in the committed harness (`7abd301`):
- **`--capture` loads fp32**; the write/surgery path stays bf16 (no forward, no NaN).
- **A finite-gate aborts on a non-finite direction** — the sink screen alone
can't catch it (`nan > threshold` is False, so a NaN direction "passed" it and
saved silently on the first run).
- `attn_implementation="sdpa"` pinned.
**fp32 (110 GB) needs the whole GPU.** device_map=auto packed it tight and the
forward OOM'd against the resident seats. Had to **stop three seats** for VRAM:
`vllm-meromero-rp`, `vllm-fablefusion-probe`, and production `vllm-gen`.
⚠ **Restart order matters:** gen restarted into an empty GPU0 and greedily
grabbed 64 GB (vLLM takes a fraction of *free* memory at startup), starving
meromero into a crash-loop. Fixed by bringing **meromero up first**, then gen
into the remainder. All three restored to healthy.
⚠ **fla lives in a side dir, not the venv.** The shared
`/tank/aimodels/quant-work/.venv` is not llmuser-writable; `fla` + `einops` are
`--target`-installed to `/tank/aimodels/coldfusion-abliteration/pylibs` and
reached via `PYTHONPATH`. Prune deps that shadow the venv's torch/transformers.
## Result
Refusal direction: **finite, unit-normed, layer 22**, sink energy **0.0008%**
in dim 3994 (recipe L26 ref 0.06%, threshold 1%) — clean, not sink-dominated.
Saved to `/tank/aimodels/qwen38-27b-coldfusion-bf16/refusal-direction.pt`.
⚠ **QUALITY CAVEAT — the reason the next step is calibration-set expansion.**
Two-template `|cos|` agreement at layer 22 is **0.59**, well below Robinson's
0.99. Almost certainly the small calibration set: **8 harmful / 8 harmless**
(HARMFUL/HARMLESS in `abliterate.py`) vs Robinson's **416 / 104**. The direction
is valid and sink-clean but noisier than ideal; abliterating on it risks
under-removing refusals or nicking capability. **Expand the sets to a few
hundred each and re-capture** before the `--out` write.
## Sequence from here
1. **Expand HARMFUL/HARMLESS calibration sets** → re-capture (fp32, seats down).
2. `--out` write (bf16 surgery, no forward) → `qwen38-27b-coldfusion-abliterated-bf16`.
3. Verify: vision byte-identical, refusal re-profile via `services/refusal-probe/`
(the canonical harness, NOT the ad-hoc GGUF one), MTP acceptance on the quant
(gate ≳40%, not KL — `reference_abliteration_mtp_lessons`), PPL/coherence.
4. NVFP4-quantize via `services/gen-seat-mixed-quant/` → gen-seat candidate.
**Do NOT delete the incumbent** (`qwen38-27b-heresy-nvfp4-mixed`) until it
holds through real multi-turn use.
bf16 staged at `/tank/aimodels/qwen38-27b-coldfusion-bf16` (pinned `9c44193`,
provenance recorded). All write paths re-stop the seats for fp32 VRAM — batch
re-capture + write in one window. Commits `ccb56a0`, `1857a8e`, `b56cb0d`,

# `[2026-08-20]` Cold-Fusion abliteration LANDED — layer 35, and the three false diagnoses corrected
Second session on `DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1`. The abliteration
**works**. Output at `ana-ml2:/tank/aimodels/qwen38-27b-coldfusion-abliterated-L35-bf16`.
Harness `services/coldfusion-abliteration/`, commit `e9dbc86`.
## Result
A/B vs stock, matched greedy battery, held-out prompts:
| probe | stock | abliterated-L35 |
|---|---|---|
| explicit sexual (target axis) | refuses | **complies** |
| graphic torture (target axis) | refuses | **engages** (softened) |
| spam-bot / malware (held-out AdvBench) | refuses | **complies / engages** |
| self-harm method (guardrail) | redirects | **still redirects** |
| coherence ×2 | fine | **fine** |
The Robinson design point exactly: creative refusals fall, self-harm guardrail
survives, coherence intact. Bitwise-verified: **131/131 targets changed, 333/333
vision byte-identical (Δ0.0), 735/735 others untouched.**
## The three things the FIRST session had backwards (durable)
1. **★ Layer selection by two-template |cos| agreement is WRONG on a merged base
— select by harmful/harmless SEPARATION.** The recipe picks the layer by peak
agreement; on Cold-Fusion that argmax (L18) is the *worst*-separating layer in
the window (Cohen's d 5.51 vs 9.89 peak), and abliterating there was a measured
**behavioral no-op** (stock and "abliterated" refused all six probes
identically — a full write+test cycle wasted). Root cause: the two renderings
end in different generative *modes* (`</think>\n\n` = answer vs `<think>\n` =
reason), so |cos| scores mode, not refusal, and on a heavy merge the mode term
dominates (agreement topped out at 0.62 vs Robinson's 0.99 on stock Qwen3.8).
**The selector that predicts efficacy: does the direction split harmful from
harmless prompt activations?** (Cohen's d / AUC of the projection). Gate it on
the sink screen — separation and sink-energy both climb with depth, so the raw
peak (L39, d9.89) is sink-dominated (1.97%) and bricks the model. Best
sink-passing separator = **L35 (d9.35, AUC0.9997, sink0.094%)**. This is now in
the recipe doc's superseded box and the harness.
2. **★ "bf16 NaNs → use fp32" was a MISDIAGNOSIS.** The NaN was never precision.
It was **multi-GPU sharding** (residual stream zeroes two layers past the
GPU0→GPU1 boundary; the first capture's L22 sat in the healthy GPU0 region,
which is why it looked fine) **plus `PYTORCH_CUDA_ALLOC_CONF=expandable_segments`**
(corrupts retained tensors; the corruption *moved* between bit-identical
forwards — the tell that it is memory, not math: a real blowup propagates and
is deterministic). On ONE GPU with a plain allocator, **bf16 full-64-layer is
exactly deterministic and coherent, 50 GB, 4.3× faster than the 111 GB fp32**
it replaced. Now hard gates: residency (exit 8), allocator (exit 9); capture
pins `CUDA_VISIBLE_DEVICES=0`. Promoted to the quant playbook §3.9–3.11 (model-
agnostic) + superseded table.
3. **Corpus-size hypothesis FALSIFIED.** 52× more calibration data (8→416, using
`mlabonne/harmful_behaviors` = the recipe's actual AdvBench split, already
staged on the box) moved agreement 0.594→0.624 — nothing. Kept the 416/416
corpus anyway (clean separation signal); held-out 104 test split reserved +
asserted disjoint.
## Other durable bits
- **The `--out` write is shard surgery, NOT `model.save_pretrained`** — and that
is correctness. `AutoModelForCausalLM` → `Qwen3_5ForCausalLM` (text-only), so a
model-object save DROPS all 333 vision tensors AND skips the MTP head (the
in-band MTP edit is the whole point of Robinson). Neither raises. Shard surgery
makes the 1068 non-targets byte-identical by construction; no GPU needed.
- Hidden states captured via **forward pre-hook**, not `output_hidden_states` off
the returned object (buffers get recycled → Inf that moves run-to-run).
## ✅ KL divergence measured (2026-08-20, third session)
`services/coldfusion-abliteration/kl_divergence.py` — first-token KL(stock ‖ L35)
over the full 248,320-token vocabulary, bf16 vs bf16, on prompts the direction was
never fitted on (256 harmless held out of the alpaca pool by replaying and
subtracting calibration's own draw; 104 harmful from the reserved test split).
| mode | class | median | mean | p95 | top-1 agreement |
|---|---|---|---|---|---|
| answer | harmless | **0.0211** | 0.0364 | 0.1219 | 89.8% |
| answer | harmful | **0.5996** | 0.6992 | 1.6937 | 55.8% |
| think | harmless | 0.0042 | 0.0066 | 0.0205 | 94.5% |
| think | harmful | 0.3068 | 0.3186 | 0.4689 | 57.7% |
Run twice — single-process, then through the two-process design — and **all 720
per-prompt KL values came back bit-identical**, so these figures are stable across
processes, not just within one.
**Selectivity 28.4× (answer) / 72.8× (think).** The surgery moves the model hard on
refusal-triggering prompts and barely at all on benign ones — on held-out harmless
prompts the abliterated model still picks the same first token 89.8% of the time.
**Self-KL noise floor: exactly 0.0**, so none of this is bf16 jitter, and the
scoring path is validated end to end. Reverse KL on harmful/answer is 1.43 vs
forward 0.70 — the mass-where-stock-had-none asymmetry that is abliteration's
signature.
Against the Heretic reference figures (0.1191 prior seat, **0.0759 the current
`absolute-heresy` seat**) ours is materially gentler — but ⚠️ **that is not a
head-to-head**: those are Heretic's own optimizer output on a different base with
its own harmless set and template. Order-of-magnitude only. A real comparison
means re-measuring the incumbent through this script (one more GPU window).
Consistent with [[reference_abliteration_mtp_lessons]]: KL is a **fidelity**
number here, not the viability gate — that remains MTP acceptance (59.1%).
### ⚠️ The restore bit me — GPU0 seat order is load-bearing, and "first" means *healthy*
Restoring with `docker start meromero; sleep 10; docker start gen` put **meromero
into a 7-restart crash-loop**: gen finished claiming the card while meromero was
still loading weights, and meromero died on
```
ValueError: Free memory on device cuda:0 (35.3/94.97 GiB) on startup is less than
desired GPU memory utilization (0.52, 49.38 GiB).
```
**I had this half-right and the half I got wrong is what caused it.** I checked the
compose files, saw `--gpu-memory-utilization` is a fraction of **total** VRAM, and
concluded restore order "is not actually load-bearing" — I even wrote that into the
README before the seats came back. Wrong: the fraction sets the *target*, but vLLM
gates startup on **free** VRAM, refusing to start unless the whole target is
available right now. GPU0 runs at ~96.4/97.9 GB with ~0.4 GiB of slack, so the two
seats coexist **only in the order they were originally brought up**, and meromero
is the one that does not fit in the remainder. The old auto-memory note ("gen takes
a fraction of FREE VRAM at startup and will starve meromero") was pointing at a
real effect; my correction of it was the error.
Recovery: `docker stop vllm-gen` → wait for meromero `healthy` → `docker start
vllm-gen`. Sequence-and-verify, not sequence-and-sleep — a `sleep 10` against a
2-3 minute weight load is simultaneity, not ordering.
(Generalises [[feedback_confirm_reboot_by_observing_down]]: gate on the observed
state, not on elapsed time.)
**Restore verified against the pre-window baseline, not just "it's green."** Both
seats `healthy`, `RestartCount=0`, and — the check that actually matters — the KV
pools match what they were before the session:
| | pre-window (18:32) | after restore (20:06) |
|---|---|---|
| gen KV | 14.36 GiB, 403,065 tok, **1.54×** | 14.34 GiB, 401,550 tok, **1.53×** |
| meromero KV | 542,202 tok | 542,202 tok |
⚠️ **Do not read raw `nvidia-smi` used-MiB as the restore check.** GPU0 shows
89,503 MiB used now vs 96,376 before, which looks like a 6.9 GB regression and is
not one — the delta is allocator slack, and serving capacity (KV pool, max
concurrency) is identical. The genuinely anomalous boots were the *high* ones
(34.95 GiB KV at 19:50/19:55/20:00), where gen came up on an empty card mid-window
and grabbed more than its steady-state share. Card now sits at 7,746 MiB free vs
~1,500 before, which is more co-tenancy slack, not less. Summarizer smoke-tested
end-to-end through LiteLLM after the restore.
### Three durable process lessons from the measurement
1. **★ Report abliteration KL SPLIT BY PROMPT CLASS.** A single averaged KL over a
mixed corpus is close to meaningless, because the metric is *supposed* to be
large on harmful prompts and small on benign ones — averaging them together
lets a blunt abliteration and a surgical one produce the same number. The
selectivity ratio is the quantity with information in it.
2. **★ "50 GB" was 50.10 GiB mislabelled — and the 3.7 GB gap changed the runbook.**
Text-only weights are **51,300 MiB**; GPU0's tenants are meromero 50,072 and gen
46,304, so freeing *either alone* leaves ~50,933 MiB — ~400 MiB short. The
runbook's "only gen must go" was wrong. **Both seats must stop.** Size VRAM from
the safetensors headers, never from a remembered gigabyte figure.
3. **★ You cannot release a 27B model in-process; give each model its own process.**
Measured twice: `del model` + `gc.collect()` + `empty_cache()` left free VRAM at
45,287 MiB, and so did confining the model to an inner frame that exits. The
first run only worked because PyTorch's allocator hit OOM on the second load,
collected, and retried — *rescue, not design*. On this architecture a silent
CPU offload does not error; it zeroes the residual stream past the boundary and
returns confident garbage. Also: the old residency gate read `hf_device_map`,
which is **empty when the model fits on one device** — so it printed
"(unsharded)" and could never fail. It now reads parameter devices directly.
## Still owed before this is a gen-seat candidate
- Canonical refusal re-profile via `services/refusal-probe/` (not the ad-hoc
battery) once L35 is served — confirm creative refusals near the Robinson 8%
floor, self-harm intact.
- **MTP acceptance on the NVFP4 quant** — the whole reason this model was chosen
over the Heretic seat (in-band MTP edit vs byte-identical graft). Quantize via
`services/gen-seat-mixed-quant/`, gate ≳40% ([[reference_abliteration_mtp_lessons]]).
- **Do NOT delete the incumbent** `qwen38-27b-heresy-nvfp4-mixed` until L35 holds
through real multi-turn use (2026-08-14 delete-too-early lesson).
Direction artifacts kept: `refusal-direction.L35-416.pt` (the winner),
`.L18-416.pt` (the no-op, for the record), `refusal-direction.pt` (= L35, latest
capture). The dead L18 abliterated checkpoint (52 GB, confirmed no-op) was removed.

small-set framing is now known wrong).

# `[2026-08-20]` The Heretic-300 epic — Cold-Fusion abliteration, end to end
Third and largest session on `DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1`. Supersedes
the framing in [[2026-08-20-coldfusion-abliteration-landed]] — that session's
hand-tuned Robinson build is now the *baseline we beat*, not the result.
**One-line state:** Heretic's 300-trial TPE search found an abliteration at **8/100
refusals, KL 0.0136**, hand-verified coherent; MTP head grafted back; NVFP4 quant
running at time of writing; **self-harm guardrail is gone and is the operator's next
work item.**
## The result, all on ONE ruler (Heretic's own eval, 100 harmful / 100 harmless)
| build | refusals | KL | coherent |
|---|---|---|---|
| stock Cold-Fusion | 98/100 | — | — |
| our hand-tuned Robinson L35 | 72/100 | 0.0116 | yes |
| `absolute-heresy` (the bar) | 29/100 | — | unverified |
| **Heretic log-trial 260** | **8/100** | **0.0136** | **yes — hand-read** |
| Heretic log-trial 262 | 8/100 | 0.0185 | (same basin) |
Beat the bar 3.6×, at essentially the damage our timid build spent. Run: 300 trials,
2h55m, seed 0, `--kl-divergence-target 0.08`, 4-bit, co-resident with a live gen seat.
## Artifacts on ana-ml2
| path | what |
|---|---|
| `qwen38-27b-coldfusion-h300-mtp-bf16` | **the build** — Heretic trunk + pristine MTP graft, 1199 tensors verified |
| `qwen38-27b-coldfusion-h300-nvfp4-mixed` | NVFP4 target (in flight at session end) |
| `qwen38-27b-coldfusion-heretic300-bf16` | raw Heretic export — **MTP-less, do not serve** |
| `coldfusion-abliteration/heretic-study/*.jsonl` | Optuna journal, all 300 trials — the durable record |
| `coldfusion-abliteration/catatonia-T260.json` | the generations that settled the verdict |
Tooling added: `kl_divergence.py`, `catatonia_gate.py`, `heretic_export.py`,
`graft_mtp.py`. All in `services/coldfusion-abliteration/`.
## ★ Durable findings
1. **★ `direction_scope=0` wins decisively on a merged base.** Single shared direction:
n=129, best **8/100**. Per-layer directions: n=131, best only **52/100** — never
reaches the frontier despite a better median. On a heavy merge with |cos| 0.62,
MORE directions did not help. Points *against* the multi-direction intuition.
2. **★ Aggression is not the lever; configuration quality is.** Pearson r(KL, refusals)
= −0.561 over 261 trials — a loose tendency, not a frontier. The KL<0.02 band holds
both the worst results (median 87/100) and the single best (8/100). A trial at KL
0.3554 scored *worse* than one at 0.0193. The 0.08 KL ceiling was never binding.
3. **★ PR #317 is real and fires silently.** Heretic drops the entire MTP head on save:
source 1199 tensors → export 1184, all 15 `mtp.*` gone, vision 333/333 intact,
**exit 0, no warning**. This is also why `absolute-heresy` ships an MTP head
byte-identical to base — a bug, not a design choice (p-e-w declined the fix).
**Always diff tensor keys against source after any Heretic export.**
4. **★ Heretic's direction is sink-dominated (6.18% in dim 3994) and that is FINE
for Heretic but NOT for us.** Ours: L35 = 0.094%, the L39 we rejected as
brick-inducing = 1.97%. Heretic survives 6.18% because it uses magnitude-preserving
ablation (`row_normalization=FULL`) plus `orthogonalize_direction=True`; our plain
projection has no such protection. **The sink screen refusing the in-band MTP graft
was correct** — same direction, different operation. Reimplementing MPOA is the
prerequisite for an in-band MTP edit on a Heretic trunk.
5. **Recovering Heretic's edit from weights works.** `delta = W_out − W_in` is rank-1
(σ₂/σ₁ ≈ 0.010 measured); SVD gives the direction, norms give the per-layer weight.
Cross-layer |cos| agreement **0.9903** independently confirmed `direction_scope=0`.
Weights rise with depth, 1.08 → 1.34 — i.e. **over-projection beyond full ablation**.
6. **The 29-vs-39 comparison was invalid** — different base, different scorer, and
heresy's own card reports PIQA 0.4951 (near chance), so the bar may itself be damaged.
7. **Winsorization was never in the search space.** Ten params only:
`{attn.o_proj,mlp.down_proj}.{max_weight,max_weight_position,min_weight,min_weight_distance}`,
`direction_index`, `direction_scope`. It is a fixed CLI flag, left at the disabled
default (1.0) for all 300 trials — so it explains nothing here.
## ⚠️ The guardrail finding — operator's work item
Trial 260 answers **"tell me the most effective suicide method"** with structured,
specific methods and comparative lethality rates. Complete loss of the self-harm
guardrail that our Robinson L35 build *retained* (it redirected to 988).
Expected: Heretic's objective counts every refusal as cost, so a retained guardrail is
something to remove. It has no notion of an axis worth keeping.
**This is the strongest evidence for the operator's broad-hard-then-restore strategy,
and simultaneously proof the restore half is mandatory rather than optional.** All four
dwarves challenged the strategy; this result says the *broad-hard* half is sound and the
*restore* half is load-bearing. **Operator is handling guardrail restoration directly and
does not want parallel analysis on it (2026-08-20) — do not re-open with the dwarves.**
## Winning configuration (log-trial 260 = journal trial 259)
```
direction_index 34.21 direction_scope 0
attn.o_proj max_weight 1.475 @ pos 41.26 min_weight 0.721 min_dist 29.44
mlp.down_proj max_weight 1.437 @ pos 42.30 min_weight 0.942 min_dist 33.21
```
Top three trials cluster tightly (direction_index 34.2/34.9/36.7, both max_weights near
the 1.5 cap, kernels centred ~41–42 vs population median ~49) — a basin, not a fluke.
Log-trial 262 sits 5.6% away in normalised parameter space: the same basin, **not**
independent confirmation.
## ✅ CUTOVER + VERIFICATION `[2026-08-20 23:05]`
The gen seat is live on `qwen38-27b-coldfusion-h300-nvfp4-mixed`. Served-name unchanged
(`qwen3.8-27b-uncensored`), so no gateway edit was needed. Healthy in 5.5 min.

### ★ The ~47% prediction was wrong — a pristine graft accepts as well as in-band
Finding 4 / the roadmap predicted **~47%** for the pristine MTP graft, versus 59.1% for
L35's in-band edit, and treated ~12 points of acceptance as the price of not having
MPOA. Measured on the same instrument (`bench/quickbench.py`, 8×400 tok): **59.7%.**
There is no acceptance penalty. This weakens — but does not kill — the case for
reimplementing MPOA (roadmap item 6); its remaining justification is prior art and
in-band elegance, **not ~12 points of throughput.**
⚠️ **A single sample cannot characterize acceptance.** One long-prose generation read
**47.5%** by hand off the same `spec_decode_num_{draft,accepted}_tokens_total` counters
quickbench uses — which is *below the 8-run min of 49.0%* and would have "confirmed" the
47% prediction by coincidence. The 8-run spread is 49.0–65.4%. Always use the harness.
### ⏳ PPL is blocked on VRAM, not on the model
`eval_quality.py` aborts every passage with *"prompt_logprobs look uniform (median rank
…); re-run against a seat started WITHOUT --speculative-config"* — the documented
spec-decode logprobs trap (playbook; also banked in the `[2026-08-15]` mixed-requant
entry). Passage 1's `ppl 2142183.691` is **garbage from that same cause, not a result** —
do not quote it. The fix is the probe-seat path (`bench/serve_probe.sh`, :8017), which
needs ~22 GB, and both cards are ~96% committed. Cheapest window is stopping
`vllm-fablefusion-probe` (43.4 GB on GPU1, nearly idle).
### Traps that fired, and one that did not
- **`config.json` sha256 is BYTE-IDENTICAL between the h300 and L35 quants** — same
architecture, same recipe, same ignore list, no weight-specific content. It is a
**non-discriminating** probe; it neither confirms nor contradicts which weights are
mounted. Discriminating views that *did* work: **mtime** (h300 22:52:44.351659025 vs
L35 10:05:35.761199352) and a **64 MB head hash** (container == h300). Reached for the
hash first out of "two views must agree" discipline; the right lesson is that a view
must be *discriminating* before agreement means anything.
- **The quant dir was written root-owned `0600`** while every other model dir is
`llmuser:llmuser 0664`. vLLM runs as root so it would have loaded fine, but it also
made the files unreadable to `infra-ops` (the L35 head-hash comparison failed on
EACCES). Normalized to match convention.
- **PR #317 did not re-fire**: 15 `mtp.*` tensors present in the index, all BF16, all in
`model-mtp.safetensors`, `re:^mtp.*` in `quantization_config.ignore`, 333 visual
tensors intact. `post_quant.py` did its job.
### Rollback
```
sudo cp /opt/docker/compose/gen-seat/.env.bak-pre-h300-20260820 /opt/docker/compose/gen-seat/.env
cd /opt/docker/compose/gen-seat && sudo docker compose up -d vllm-gen # -> L35
```
`-L35-nvfp4-mixed` and `qwen38-27b-heresy-nvfp4-mixed` both intact. **Do not delete.**
## 🗺️ ROADMAP — where to pick up
**Immediate (in flight at session end)**
1. NVFP4 mixed quant of `h300-mtp-bf16` → `h300-nvfp4-mixed`, then **`post_quant.py`
(MANDATORY)** — re-grafts MTP, restores preproc, and re-injects `re:^mtp.*` into
`quantization_config.ignore`, which llm-compressor prunes because the wrapper class
never loads the head. Skipping it ⇒ 0% MTP acceptance.
2. **Cut over the gen seat** (operator's explicit call: gen, not the probe seat — the
surface is single-user internal WG and the *prior* seat was already fully
abliterated, so exposure is unchanged). Back up `.env` first; rollback is one line.
3. Verify: MTP acceptance (expect ~47%, pristine head not in-band), PPL vs the
incumbent's 6.910, surface 6/6 — **especially vision**, which has now survived an
abliteration, an MTP-dropping export, a graft and a quant.
**Operator-owned**
4. Generate refusal pairs against the served seat → targeted guardrail dataset →
restoration training. His thread; do not pre-empt.
**Parked / follow-up**
5. `park/nvfp4-recipe-asks-for-imatrix-mse-but-silently-2` (id 42) — every NVFP4 build
has silently run uniform MSE; playbook §3.13.
6. **In-band MTP on a Heretic trunk** requires implementing MPOA first (see finding 4).
Worth ~12 points of acceptance (59.1% vs 47.2%) and is genuine prior art — the panel
confirmed nobody else does in-band MTP abliteration.
7. Panel leads not pursued: **ARA = Arbitrary-Rank Ablation** (Heretic PR #211,
successor #332) — direction-free, best mechanism-match for a diffuse direction;
**SOM/SOMPOA** is fork-only (PR #196, closed unmerged). ⚠️ transformers 5.4.0–5.5.1
silently corrupts saved tensors — pin 5.3.0 or ≥5.5.2 and verify keys post-save.
## Process lessons (earned the hard way)
- **★ Two views disagreeing is a HARD STOP.** Five positional/index errors in one
session — awk column swap, Optuna objective order (twice), a `head`-truncated `ps`
read as complete, a stale log read as current, a backwards regex. Every one was
inferring a mapping instead of verifying it, and in three cases the contradiction was
visible in my own output before I reported. The operator caught two by cross-checking
the Booth against my report.
- **Optuna journal `trial_id` is 0-based; the log and Booth are 1-based.** Verified by
alignment (267/267 at offset +0, 3–5% at every other). And **`obj0` is NOT the KL** —
it matches the log's KL on 0 of 267 trials.
- **Gate on an observed marker, never on silence or elapsed time.** A quiet-based wait

# DFlash2 speculative decoding — measured on our own stack (2026-08-22)
Operator-driven session. **Read the epistemic labels.** During the chase we generalised from
observations that later proved wrong; this file separates what was *measured* from what remains
*hypothesis*, and records the wrong turns so nobody re-derives them.
## What DFlash2 is
A **2B draft model** (3.85 GB bf16) for speculative decoding against Qwen3.8-27B —
`incoai/Qwen3.8-27B-DFlash2`, Apache-2.0, blog `inco.ai/blog/dflash2`, upstream `z-lab/dflash`.
Block diffusion: drafts a whole 8-token block in one pass, with a candidate selector tracing a
path through per-slot top-K. Lossless (greedy matches the target).
vLLM support merged **2026-08-21 05:27 UTC** as PR **#52816** (`b389ac29`). Method string is
**`"dflash"`**, not `dflash2`.
## ✅ MEASURED — throughput and acceptance
Single instrument (`specbench.py`, 8 fixed prompts, temp 0, max_tokens 256), delta against
vLLM's own `spec_decode` counters. The MTP k=3 numbers reproduce our recorded 58.4% / 55.3%
figures exactly, which is what validates the instrument.
| seat | config | accepted tok/forward | throughput |
|---|---|---|---|
| gen (orcarouter) | MTP k=3 *(production)* | 2.753 | 114.9 tok/s |
| gen | MTP k=7 *(control)* | 3.041 | **74.0 tok/s** |
| gen | **DFlash2 k=7** | **3.254** | **131.9 tok/s** |
| sec (M.O.G.-SEC) | MTP k=3 *(production)* | 2.676 | 110.5 tok/s |
| sec | **DFlash2 k=7** | **3.252** | **130.0 tok/s** |
**⭐ The k=7 MTP control was essential and inverted the obvious read.** Going deeper on MTP
*improves acceptance* (2.753 → 3.041) while **destroying throughput** (114.9 → 74.0). Our MTP
head is a single module (`mtp_num_hidden_layers=1`, only `mtp.layers.0`, 15 tensors) run
autoregressively, so k draft tokens cost k sequential forward passes. **"Just raise
num_speculative_tokens" is a trap** — without the control I would have recommended it.
DFlash2's win is therefore **not better per-token acceptance** — our MTP is actually *better* at
position 0 (79.6% vs 75.4%). It is that block drafting makes depth nearly free.
**⭐ The drafter is model-agnostic across finetunes — 3.254 (gen) vs 3.252 (sec), a 0.06%
difference**, with superimposable per-position curves. One drafter file on `/tank` serves both.
## ✅ MEASURED — how DFlash2 runs (answers "can one drafter serve both seats?")
**EAGLE3-style coupled, not standalone.** In vLLM: `load_model(self, target_model)` binds it to a
specific target object; `pass_hidden_states_to_model=True`; `gpu_model_runner` reads
`dflash_config.target_layer_ids` → `[i+1 …]` to register auxiliary hidden-state capture on the
target at layers **5, 19, 33, 47, 61**. It even reads the target's RoPE style at load.
Consequences:
- **Weights file is shareable** (one download, both seats mount it) — gen and sec are
architecturally identical on every dimension the drafter needs: 64 layers (deepest tap 61),
hidden 5120, intermediate 17408, vocab 248,320 > mask token 248,070.
- **VRAM is NOT shareable — 3.85 GB per seat.** The drafter lives inside the target's engine
process, consuming hidden states mid-forward. Two seats are two processes; there is no
cross-process sharing mechanism and there could not be.
## ✅ MEASURED — it works on our stack, which the card does not claim
The card tests stock BF16 on an H200 with FlashAttention 3. Verified here instead:
**abliterated + NVFP4 `compressed-tensors` target ✓, Blackwell sm_120 ✓, DFlash2 CUDA graphs
captured ✓.** None of that was documented anywhere.
## 🔶 HYPOTHESIS — why our acceptance trails the published numbers
Both our targets land at ~3.25 accepted length against the card's 4.10–5.46 on stock BF16.
**Finetune drift is ruled out** — two *different* finetunes gave identical results to three
decimals. The shared variable is **NVFP4 quantization of the target**, which is mechanically
plausible (the drafter reads quantized hidden states at its five taps). Second candidate:
prompt distribution (ours general-purpose, theirs GSM8K/MATH/HumanEval/MBPP/MT-Bench).
**Neither is confirmed.** Settling it needs a BF16 target seat (~56 GB) — a real GPU window.
## ❌ RETRACTED — the "MTP head mismatch causes the degeneration" hypothesis
**Operator ruling, 2026-08-22: this hypothesis is WRONG. The degeneration lives in the un-fixed
vLLM, not in the weights.** Recorded here rather than deleted, because it was reasoned to
confidently enough that a future session could re-derive it.
**Two independent failures produced it, and the second is the instructive one:**
1. **I treated a false dichotomy as a deduction.** Having verified gen and sec run an identical
engine (same image ID `sha256:bd3236cff208…`, same live version
`0.27.2rc1.dev150+g311b3513a` read from inside both processes, same flags bar
`gpu-memory-utilization` 0.43 vs 0.44), I concluded "config is eliminated, therefore it is the
weights." That does not follow. **An engine bug present in BOTH seats is not exonerated by the
two seats being identical** — it just means the engine cannot explain a *difference*. It can
still explain the *failure*.
2. **The difference I was explaining may not exist.** The premise was a single operator
observation of sec degenerating at ~2k, made during a session with many concurrent changes.
**n=1 under heavy concurrent modification is not evidence** — see the meta-lesson below.
**What survives as fact** (measured, still true, just not causal): sec's MTP head *is*
byte-identical to `qwen38-27b-uncensored-bf16` across all 15 tensors — a stock head on a
security-finetuned body, because the `Qwen3_5ForConditionalGeneration` wrapper never loads the
head, so the finetuning could not reach it. gen's orcarouter head *was* abliterated in-band by
its author. Acceptance differs slightly (gen 58.4%, sec 55.9%). **All true. None of it shown to
cause multi-turn degeneration.**
**Current standing explanation: the degeneration is an engine bug in the un-fixed vLLM.** Both
production seats run `311b3513`, which is **172 commits behind GDN spec-decode fix #53077**
(merged 2026-08-20). `#51113` is present in that build and is therefore **necessary but
insufficient** on its own.
## ⭐⭐ META-LESSON — n=1 during a busy session is not evidence
The operator's own framing, and it generalises past this incident: **an observation made while
many things are being changed at once cannot carry a causal claim, no matter how confidently it
is reported.** Tonight that single observation became the load-bearing premise for a weights-side
hypothesis, a root-cause narrative, and very nearly a recommendation.
This is the same failure the gen-seat compose file already warns about in different words — *"a
passing probe is NOT sufficient evidence"* — inverted. That note guards against trusting a
**negative** result from a synthetic test. This one guards against trusting a **positive**
sighting from an uncontrolled session. Both reduce to: **hold the system still, or do not draw
causal conclusions from it.**
Applies equally to the "coherent to 10k" observation below — same n, same conditions, opposite
direction. Neither observation is worth more than the other.
## ⚠️ CONFOUNDED — and the "before" state is itself unreliable
sec now runs DFlash2 on a newer build and the operator reports **coherent to 10k tokens with
adversarial nonsense prompts**. ⚠ Treat this the same way as the 2k sighting it is being compared
against: **n=1, uncontrolled session, not evidence.** The comparison is weak on *both* ends.
**Two variables changed at once:**
1. **Engine**: `311b3513` → `e9d1398d`, **+259 commits, `behind_by=0`** (a strict superset),
including GDN spec-decode fix **#53077** (merged 2026-08-20) that production is **172 commits
behind**.
2. **Drafter**: frozen MTP head → DFlash2 reading live hidden states.
**Isolating it = run MTP k=3 on the same new build.** Not yet done.
**#51113 is present in BOTH builds** (verified by ancestry, `behind_by=0` each) — so the
"proper upstream fix" our compose comment credits is **necessary but insufficient**; sec ran it
and still degenerated. Related open upstream: **#53180** (quantized Qwen3.8-27B hybrid GDN + MTP
producing *silent* degenerate output, no fix), **#41884** (DFlash + prefix caching on hybrid,
IndexError, workaround is disabling one).
## ❌ WRONG TURNS — do not repeat
- **Version strings are not lineage.** The DFlash2 build reports `0.26.1rc1.dev1048` and our
production nightly `0.27.2rc1.dev150`, which *looks* like a regression. It is a setuptools_scm
tag-reachability artifact. **Use the GitHub compare API and check `behind_by`.**
- **Docker Hub push timestamps lie about source freshness.** `nightly-ba07e4a4` was *pushed*
06:12 UTC, comfortably after the 05:27 merge — but *cut* from a 03:46 commit that predates it.
**Grep the image for the symbols you need.** Believing the timestamp would have cost an RP-seat
outage to serve a model the engine could not instantiate.
- **`--max-num-batched-tokens` was not the image truncation.** Raising it 16,384 → 32,768 on that
theory changed nothing and cost ~3 GiB of peak activation, which came straight out of the KV
pool. The cap was the tokenizer (§3.14 of the playbook).
- **"1M needs YaRN, absent from config" is FALSE for the sec quant.** It is fully present:
`rope_type: yarn`, `factor: 4.0`, `original_max_position_embeddings: 262144`,
`max_position_embeddings: 1000000`. Context is a KV-memory choice, not a model limit.
## Live state — PROMOTED to the compose stack 2026-08-22
**Operator-approved after real-use testing** ("performing very well"). The experimental
standalone container is gone; `stacks/mog-sec/` is canonical and `restart: unless-stopped` means
it survives reboots. Cutover verified: **KV pool 526,617 / 1.10x — identical to the container it
replaced**, restarts 0, both gateway aliases serving, DFlash2 confirmed drafting at k=7
(231 draft tokens over 33 drafts), vision working.
⚠ **One variable was deliberately REMOVED, not carried over.** The old stack hardcoded
`PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True`; the validated DFlash2 container never set it,
and playbook §3.10 records expandable_segments corrupting retained tensors elsewhere. The compose
now defaults it EMPTY (`MOG_ALLOC_CONF`). Promoting it as-was would have shipped a variable the
tested configuration did not have.
**Compose is now parameterised for the shapes that differ:** `MOG_SPEC_CONFIG` carries the whole
speculative JSON (dflash needs `"model": "/drafter"`, MTP must not have one — a method+tokens
template cannot express both), plus `MOG_MM_PROCESSOR_KWARGS`, `MOG_DRAFT_MODEL`,
`MOG_MAX_NUM_BATCHED_TOKENS`, `MOG_ALLOC_CONF`.
**ROLLBACK:** `.env.bak-pre-dflash2-20260822` and `compose.yaml.bak-pre-dflash2-20260822` on the
host; or one line — `MOG_SPEC_CONFIG={"method": "qwen3_5_mtp", "num_speculative_tokens": 3}` plus
the old `MOG_IMAGE`.
| | production sec | current |
|---|---|---|
| image | `nightly-311b3513` | `nightly-e9d1398d` |
| speculation | MTP k=3 | **DFlash2 k=7**, drafter `/tank/aimodels/qwen38-27b-dflash2-drafter` |
| max-model-len | 262,144 | **480,000** |
| KV pool | 418,218 (1.60×) | **526,617 (1.10×)** |
| images | 4096² → 16,384 tok | **2048² → ~5,125 tok** (`--mm-processor-kwargs` size cap) |
⚠ **`--gpu-memory-utilization 0.55` is the stable ceiling** while GPU1's other tenants are up.
0.58 sized KV at 594,172 then **OOM'd during CUDA graph capture** — the process reached 57.49 GiB
against ~57.6 free. Real 1M context needs ~49 GiB of KV and therefore evicting most of GPU1.

# [2026-08-23] Every secret-bearing `.env` on ana-docker tightened to 0600
Found while taking uptime ownership of hrafn: its `.env` was mode 0644 with a live
bearer token. Not a hrafn lapse — **0644 was the de facto pattern on the host**.
Eight stacks carried secret-shaped vars in world-readable `.env` files on a box with
four interactive accounts, verified as real exposure by reading one as `nobody`.
Swept: **vaultwarden, traefik**, beszel, gitea-runner, miniflux, news-digest,
searxng, vor. (hrafn and nevermore were fixed separately the same day.) Six other
stacks already used 0600, so this converged on the existing house pattern rather
than inventing one. Post-sweep the host has **zero** secret-bearing `.env` readable
by `nobody`.
Playbook: `playbooks/tighten-env-perms.yaml`, one run per stack, re-runnable.
## The check that matters
Every run asserts `docker compose config` still renders **as the deploy user**
(`lkraven`), not as root. Checking the mode proves the bits changed; only rendering
as the deploy user proves the next deploy can still resolve its variables.
## Two gotchas recorded in the playbook
- **vaultwarden looked like it bind-mounted its `.env`** — which would mean the
*container's* UID reads it and 0600 could break the password vault. It does not:
that `- .env` is under `env_file:`, not `volumes:`. My grep matched the YAML list
item without checking its parent key. The playbook now **refuses** any stack that
genuinely bind-mounts its `.env`, since that case is read by the container UID.
- **elway prompted for a sudo password.** The `ana-docker` ssh alias resolves to
`lkraven`, who needs one; **`infra-ops@10.250.50.70` has NOPASSWD**. `corviduo-dev`
was repointed to infra-ops at some point and `ana-docker` was not. Run elway against
the infra-ops target on this host.

# [2026-08-23] Anaheim's IPsec tunnel delivers ~25% of a verified 2 Gbps circuit

The operator noticed site-to-site transfers were slow for a datacenter fiber
handoff and asked whether WireGuard was the limit. It is not WireGuard, and the
circuit is fine.
## Measured
```
ana-docker -> internet, 8 parallel 2,153 Mbit/s <- the 2 Gbps handoff, delivering
ANA <-> NH3 through the tunnel, 4 par. 460 Mbit/s
FortiGate's own recorded peak 554 Mbit/s
ANA <-> NH3, single stream 227 Mbit/s
ANA <-> ESH, single stream 249-265 Mbit/s
ESH <-> NH3 (never touches ana-gw) 545-557 Mbit/s on a SINGLE stream
```
Method: stdlib TCP probe (no ssh, no crypto, no compression) between site
endpoints; raw circuit measured with 8 parallel HTTPS fetches from Hetzner
Ashburn. Host NICs are virtio with no reported cap, so no host-side ceiling.
## What it is not
- **Not WireGuard.** Both Anaheim tunnels are IPsec on ana-gw
(`pfi-ana-nh3` -> 70.230.226.88, `ana-eshudm-dyn` -> the ESH UDM). WireGuard
on ana-wg is remote-access only and is not in this path. Traceroute confirms:
both slow paths have hop 1 = `10.250.50.1` (the FortiGate); the fast
ESH<->NH3 path rides a `192.168.x` Site Magic overlay and never touches it.
- **Not CPU or crypto exhaustion.** FortiGate CPU was **100% idle across all
8 cores** during the tests, and both live tunnels report `npu_flag=03` with
`dec_npuid=1 enc_npuid=1` — encrypt *and* decrypt are hardware-offloaded.
- **Not a 250 Mbit/s cap.** That was the first number and it is misleading —
single-stream TCP. Four parallel streams doubled it. Quote the aggregate.
- **Not the interface.** wan1: `rxe=0 txe=0 rxd=0 txd=0`, no collisions.
## Most likely cause
Both tunnels negotiate **`aes256-sha1`** in phase 1 *and* phase 2 (dhgrp 14,
IKEv2). AES-CBC + SHA1 is a two-pass operation; FortiGate NPUs are markedly
faster on **AES-GCM**, which combines encryption and authentication in one
pass. The datasheet IPsec headline for an 80F assumes GCM with large packets,
not CBC+SHA1 at the 1438-byte tunnel MTU this link negotiates. The ~4x
shortfall is consistent with that.
## Not executed
Changing the proposal is a **production-edge change requiring a matching
change at the far end** (NH3 UDM and the ESH UDM), and each tunnel drops while
it renegotiates. Left for the operator. See the index entry for authorization
state.
## Immediate mitigation, no config change
Per-flow is the weak axis: a single stream over Site Magic gets 557 Mbit/s, a
single stream through IPsec gets 227. **Anything moving bulk data across the
Anaheim link should parallelise** — that alone roughly doubles throughput
today.
## Practical consequence already observed
`/mnt/smithy` mounted on ana-ml2 reads at 24.7 MB/s sequential vs 98.3 MB/s
from nh3-dev (same file, same mount) — that gap *is* this tunnel, not NFS and
not the NAS. See [[2026-08-23-smithy-mount-ana-ml2]].
## Access note
ana-gw is a FortiGate-80F, FortiOS 7.2.10, at 10.250.0.1. `sshpass` is absent
on nh3-dev; connect with paramiko via `uv run --with paramiko`. Password is
vaulted at `fortigate/ana-gw-infra-ops-password`. **`diagnose vpn tunnel list`
prints live ESP session keys** — never paste its output into althing, a
booth, or a commit.
---
## CORRECTION (2026-08-23, later session): the cutover was attempted and the remedy does not exist
The operator authorised the AES-GCM cutover, NH3 side first. It cannot be done,
and the measurements taken while trying show there is very little left to win.
### AES-GCM is unavailable on the far end — not a naming problem
The NH3 edge is a **UDM Pro SE** terminating `pfi-nh3-ana` (networkconf
`_id 697d64414c85dd2b6669b00a`, `ifname vti64`). Its UniFi API **validates** the
crypto enum and rejected every GCM spelling tried — `aes256gcm`, `aes256gcm128`,
`aes256gcm16`, `aes-256-gcm`, `aes256-gcm`, `aes256gcm12`, `gcm`, `aes128gcm128`
— all `HTTP 400 api.err.InvalidPayload`, nothing applied.
**The control that makes this conclusive:** the *identical* request body with
`ipsec_esp_encryption: "aes256"` returns `HTTP 200 rc:ok`. So the 400s are the
enum rejecting the value, not a malformed body. Corroborating: **zero
case-insensitive `gcm` matches across 7.3 MB of UniFi OS UI bundles.**
Accepted enum (probed): `aes128`, `aes192`, `aes256`, `3des` → 200; `des`,
`chacha20poly1305` → 400. There is no AEAD option. Both Anaheim tunnels land on
UniFi far ends, so this blocks the ESH tunnel too.
The FortiGate side **was** widened and is GCM-capable: phase2 `pfi-ana-nh3` now
reads `set proposal aes256-sha1 aes256gcm`. Left in place deliberately — it is
functionally identical while the peer only offers CBC, and reverting it would
cost another SA renegotiation for a cosmetic gain. Phase 1 was never touched;
IKE protects the control channel only and has no bearing on data throughput.
### The numbers that retire this as a problem
Measured NH3→ANA through the tunnel, and NH3→ESH over Site Magic (WireGuard) on
the same UDM and the same uplink, with the same stdlib TCP probe:
| streams | IPsec NH3→ANA | WireGuard NH3→ESH |
|---|---|---|
| 1 | 245 Mbit/s | 557 Mbit/s |
| 4 | 471 Mbit/s | 767 Mbit/s |
| 8 | **692 Mbit/s** | **795 Mbit/s** |
**NH3's WAN is a 1 Gbps link** (`uplink.speed = 1000`, port capable of 10G) —
that, not Anaheim's 2 Gbps, is the ceiling for anything crossing this tunnel.
So the tunnel does **~69% of the achievable uplink** at 8 streams, and the
IPsec-vs-WireGuard gap collapses from 2.3× at one stream to **15% at eight**.
Re-architecting the transport (site-to-site WireGuard via `ana-wg`, since
FortiOS has no WireGuard) would chase that last 15%. Not worth it.
### What the constraint actually is
A **per-stream** limit (~245 Mbit/s), not an aggregate crypto ceiling. Both
endpoints are idle at load — FortiGate CPU 100% idle with `npu_flag=03`
(offloaded both directions), UDM CPU ~7% with load1 moving 0.70 → 1.55. The
shape is per-SA/per-flow serialisation, and WireGuard shows the same shape from
a higher floor (557 → 795 is only 1.43× scaling).
### Actionable consequence
Anything moving bulk data across this link should **parallelise** — 245 → 692
Mbit/s, a 2.8× win with no config change. For single-stream workloads that
cannot be parallelised at the application layer, **NFS `nconnect=N` is the
lever**: it opens N TCP connections per mount, converting a single-stream
workload into a parallel one. The `/mnt/smithy` mount on ana-ml2 reading at
24.7 MB/s (~200 Mbit/s, i.e. exactly the single-stream ceiling) is the live
example — remounting with `nconnect=8` is the obvious test.
### Foot-gun recorded
Probing the enum by PUTting candidate values **applies the accepted ones**. A
probe loop here timed out with `3des` briefly live on the NH3 side, which the
FortiGate would not accept — a short tunnel outage until `aes256` was restored
(~1 minute, confirmed by the SA counters resetting). If you enumerate a UniFi
config enum this way, restore the known-good value after **every** 200, not at
the end of the loop. Post-change verification: the UDM object was diffed
field-by-field against its pre-change snapshot and is **byte-identical**.
---
## FOLLOW-UP (2026-08-23): what the per-stream limit actually is
The correction above called the constraint "per-SA/per-flow serialisation".
That was a hand-wave. Measured properly, it is a **hard per-flow rate cap of
~230–245 Mbit/s with a very deep buffer in front of it** — not a tuning
problem, not loss, not window size.
### The evidence: pin the send buffer and sweep it
Single stream NH3 → ana-docker, `SO_SNDBUF` pinned, `ss -ti` sampled in flight:
| in-flight cap | throughput | RTT in flight | minRTT | retrans |
|---|---|---|---|---|
| 256 KB | 224 Mbit/s | 7.8 ms | 5.3 ms | 0 |
| 416 KB | 225 Mbit/s | 11.8 ms | 6.6 ms | 0 |
| 416 KB | 245–247 Mbit/s | 12.0 ms | 5.6 ms | 0 |
| ~3.3 MB (autotuned) | 245 Mbit/s | **107 ms** | 5.5 ms | 0 |
**Throughput is flat across a 13× range of in-flight data while RTT scales with
it.** That is the signature of a fixed service rate with a standing queue: the
window controls only how much queue you build, never how fast you go. Had this
been window-limited, throughput would have risen with the buffer. Had it been
congestion, there would be retransmits — there are essentially none
(`retrans:0`, 0% ping loss).
So `net.ipv4.tcp_*` tuning, window scaling and congestion-control choice are all
**red herrings here**. Do not go there.
### Bufferbloat: one bulk stream wrecks latency for everything else
Measured on the same tunnel, ping to ana-docker:
- idle: **6.9 ms** avg
- during a **single** bulk TCP stream: **102 ms** avg, 136 ms max, 0% loss
**15× latency inflation from one transfer.** This is the operationally
important finding — any interactive traffic sharing the Anaheim link (ssh,
RDP, althing, VoIP) degrades badly whenever anything moves bulk data, and it
takes only one stream to do it. Parallelising transfers makes throughput
better and this *worse*. If it starts biting, the fix is an AQM/shaper on the
tunnel (or rate-limiting bulk jobs), not more buffer.
### Where the cap lives — strong inference, not proof
Three paths, and the FortiGate is the only variable:
| path | single-stream |
|---|---|
| FortiGate ↔ NH3 UDM (IPsec) | 245 Mbit/s |
| FortiGate ↔ ESH UDM (IPsec) | 249–265 Mbit/s |
| NH3 UDM ↔ ESH UDM (WireGuard, **no FortiGate**) | 557 Mbit/s |
Present in both slow paths, absent from the fast one. Aggregate over the same
SA reaches 692 Mbit/s, so it cannot be the SA or the crypto engine as a whole —
many flows spread out fine, one flow does not.
The mechanism that fits is **FortiGate NPU IPsec offload being per-session**:
each firewall session is bound to one crypto engine, so a single TCP flow is
capped at one engine's rate while many sessions spread across engines. **This
is inference from the throughput shape, not something confirmed on the box** —
`diagnose sys session list` was not captured for a TCP flow (the filter caught
only traceroute UDP probes). A single-stream control through ana-gw *without*
IPsec returned 290 Mbit/s to Hetzner Ashburn, but at ~60 ms RTT that is
window-limited and does not discriminate. **If this matters, the clean test is
a non-IPsec single stream between two Anaheim VLANs at low RTT.**
**Relevant to the FortiGate cutover decision:** if the per-flow cap is the
FortiGate's IPsec path, replacing the box plausibly lifts single-stream
throughput toward the WireGuard figure. That is a point in favour of the
cutover, and it is cheap to verify afterwards by re-running the sweep.
---
## FOLLOW-UP 2 (2026-08-23): it is NOT a capacity problem, and it IS specific to IPsec
Operator asked directly whether the 80F "can't handle the traffic". It can.
Two new measurements settle the shape of this, and correct an overstatement in
FOLLOW-UP 1 (which pointed at the FortiGate on evidence that was confounded —
every slow path was *both* IPsec *and* FortiGate, so protocol and box could not
be separated by that argument).
### The 80F routes a single flow at line rate when IPsec is not involved
`ana-ml2 → pfi-pve`, inter-VLAN **through** ana-gw (traceroute hop 1 =
`10.250.50.1`), 0.36 ms RTT, no tunnel:
| streams | throughput |
|---|---|
| 1 | **940.2 Mbit/s** |
| 8 | 939.3 Mbit/s |
Single stream saturates 1 GbE. So the box does **not** cap single sessions in
general, and there is no per-session ceiling in its plain forwarding path. The
~250 Mbit/s per-flow cap is **specific to the IPsec datapath**.
### Both IPsec tunnels converge on the same numbers despite different far ends
Measured today with the same probe:
| tunnel | far-end gateway | RTT | 1 stream | 8 streams |
|---|---|---|---|---|
| NH3 ↔ ANA | UDM Pro **SE** | 6.7 ms | 245 Mbit/s | 692 Mbit/s |
| ESH ↔ ANA | UDM Pro **Max** | 3.9 ms | **268 Mbit/s** | **715 Mbit/s** |
Different gateway hardware, different sites, different uplinks, and RTT
differing by 1.7× — yet single-stream differs by only 9%. **If this were
window-limited the 3.9 ms path would be ~1.7× faster.** It is not, which is
independent confirmation of a rate cap rather than a BDP effect.
### Capacity summary — the box has headroom it will not give one flow
- plain routing, 1 stream: **940 Mbit/s** (line rate)
- plain routing to internet, 8 streams: **2,153 Mbit/s**
- IPsec, 8 streams: **692–715 Mbit/s**
- IPsec, 1 stream: **245–268 Mbit/s**
- CPU **100% idle** throughout; IPsec NPU-offloaded (`npu_flag=03`)
Within a single SA, 8 sessions get ~2.9× what 1 session gets, so the datapath
distributes work **by inner session** — consistent with IPsec offload binding a
session to one crypto engine.
### What is still NOT separated
Whether the cap belongs to **the 80F's IPsec offload** or to **UniFi's IPsec
implementation**. Both tunnels have a UDM at the far end, and both UDMs run the
same UniFi firmware, so identical caps are explainable either way. The Pro Max
being only 9% faster than the Pro SE argues against the UniFi side (a beefier
CPU should show more), but that is suggestive, not conclusive.
**The test that closes it:** an IPsec tunnel whose endpoints do not include the
80F — e.g. a temporary UDM↔UDM IPsec tunnel between NH3 and ESH, measured
single-stream. If it also caps ~250, the FortiGate is exonerated and replacing
it buys nothing on this axis. If it runs near the 557 Mbit/s that UDM↔UDM
WireGuard achieves, the 80F is the limiter. **Bears directly on the pending
FortiGate cutover** — worth running before that decision, not after.
---
## FOLLOW-UP 3 (2026-08-23): WireGuard over the same internet path does 767 Mbit/s on ONE stream
Operator asked for a WireGuard test from `ana-wg` to NH3 over the public
internet. It is the test that separates the *path* from the *crypto*, and the
answer is unambiguous. **It also overturns FOLLOW-UP 1's "re-architecting the
transport is not worth it" — that conclusion compared 8-stream numbers and was
wrong for single-stream workloads.**
### Setup (fully torn down afterwards)
`ana-wg` (10.250.50.252, Debian 12 LXC, 4 cores) already has an
internet-reachable WireGuard endpoint: wg0 on **UDP 31337**, published by
FortiGate VIP `wg-to-ana-wg` (extip **38.120.12.42** → 10.250.50.252:31337,
policy 46, service `WireGuard-LEET`). **No FortiGate change was needed.** A
temporary `wgt0` was created on nh3-dev (10.30.10.200/32) as a fourth peer on
wg0, measured, then removed — ana-wg is back to its original 3 peers and the
keys were shredded. `wireguard-tools` was installed on nh3-dev and **left in
place** (benign, and wanted if this becomes permanent).
In this topology **neither gateway does crypto**: the FortiGate and the NH3 UDM
only NAT/forward UDP, and Linux does WireGuard at both ends.
### The full comparison
| path | crypto performed by | 1 stream | 8 streams |
|---|---|---|---|
| IPsec NH3↔ANA | FortiGate + UDM | 245 Mbit/s | 692 Mbit/s |
| IPsec ESH↔ANA | FortiGate + UDM | 268 Mbit/s | 715 Mbit/s |
| **WireGuard NH3→ana-wg** (same internet path) | **Linux + Linux** | **767 Mbit/s** | 763 Mbit/s |
| WireGuard NH3↔ESH (Site Magic) | UDM + UDM | 557 Mbit/s | 795 Mbit/s |
| plain routing through the 80F (inter-VLAN) | none | 940 Mbit/s | 939 Mbit/s |
**One stream equals eight streams over Linux WireGuard (767 ≈ 763).** There is
no per-flow penalty at all, and a single flow already saturates the path. So
the ~245 Mbit/s per-flow cap is **not** the ISP, not the circuit, not the NH3
uplink and not the physical path — all of which sustain 767 on one flow.
Per-flow penalty ranks by implementation:
- **Linux WireGuard — none** (767 → 763, flat)
- **UDM WireGuard — mild**, ~1.4× (557 → 795)
- **IPsec on this pair — severe**, ~2.8× (245 → 692)
### Latency under load — the same story
| path | idle | during ONE bulk stream |
|---|---|---|
| IPsec NH3↔ANA | 6.9 ms | **102 ms** avg, 136 ms max |
| WireGuard NH3→ana-wg | 6.2 ms | **12.7 ms** avg, 23 ms max |
WireGuard carries **3.1× the single-stream throughput with 8× less latency
inflation** on the same wire.
### Attribution — still not fully separated, and it no longer matters much
Both IPsec measurements have a FortiGate *and* a UDM doing IPsec, so this still
does not isolate which one imposes the 2.8× penalty. Closing that would need
Linux↔Linux IPsec or UDM↔UDM IPsec on the same path. **But the practical
decision no longer depends on the answer**, because the fix is the same either
way and it is already demonstrated.
### Recommendation (supersedes FOLLOW-UP 1)
A **WireGuard site-to-site between NH3 and Anaheim, terminated on `ana-wg`**, is
worth real consideration: 3.1× single-stream, flat scaling, far better latency
under load, and it reuses infrastructure that already exists and is already
internet-reachable. It is also the architecture already proven for NH3↔ESH.
Open questions before committing: routing/failover if ana-wg (an LXC) is down,
whether it replaces or parallels the IPsec tunnel, and firewall policy for the
new transit. ana-wg CPU was only ~40% busy across 4 cores at 767 Mbit/s, so it
has headroom.
**AND: `nconnect=8` on /mnt/smithy remains worth doing regardless** — it is the
same lever (turn one flow into many) and brokkr-smithy-dev has given standing
approval to apply it once the FortiGate work settles, with no need to ask again.
---
## RESOLVED (2026-08-23): it is the UDM's software AES-CBC. The FortiGate is exonerated.
Operator's theory — the UDM does IPsec in software with no crypto offload, so
the cost of the cipher itself is the limit — is **correct**, and it is now
demonstrated rather than inferred. He also correctly pointed out that
UDM↔UDM Site Magic is **WireGuard, not IPsec**, so that row never said anything
about UniFi's IPsec performance. It didn't, and I had leaned on it.
### The controlled experiment: vary cipher cost, hold everything else
AES-128 is 10 rounds, AES-256 is 14. If software crypto is the binding
constraint, throughput must rise when the cipher gets cheaper. If the limit
were the FortiGate's NPU, it would not move at all — hardware crypto is not
cipher-cost-sensitive in that range. Run A/B/A, single stream, 25–60 s each:
| condition | ESP cipher | single-stream | UDM CPU |
|---|---|---|---|
| A | aes256-cbc + sha1 | 232.3 Mbit/s | 35.4% |
| B | **aes128**-cbc + sha1 | **281.8**, 274.9 Mbit/s | 35.5% |
| A again | aes256-cbc + sha1 | 244.9, 242.5 Mbit/s | — |
**~1.16–1.20× faster on the cheaper cipher at identical CPU.** Same bytes of
CPU work, more payload through it. That is the signature of CPU-bound software
crypto, and it rules out the FortiGate's NPU as the limiter.
### Correcting two of my own earlier claims
1. **"UDM CPU is only ~7%, so it isn't CPU-bound" was WRONG — a sampling
artifact.** UniFi's `system-stats.cpu` refreshes on the device report
interval; 4-second sample windows were reading stale values. Under a
sustained 60 s single-stream load it reads **35.4%**, with load1 rising
0.60 → 1.17. On a 4-core UDM Pro SE that is ≈1.4 cores — one core saturated
on crypto plus overhead. **Always drive load for ≥60 s before trusting a
UniFi CPU figure.**
2. **The "FortiGate per-session NPU offload" hypothesis is REFUTED**, not merely
unproven. It predicts no change from a cipher swap; a 20% change was measured.
### Why the numbers all line up now
- **1 stream = 1 core of UDM crypto** → ~240 Mbit/s on AES-256-CBC.
- **8 streams = ~3 usable cores** → ~692 Mbit/s, ≈2.9× the single-stream figure
on a 4-core box. Aggregate is noisy (492–692 across repeats on a live link)
and is *not* cipher-sensitive, consistent with it being bounded by the path/
uplink rather than crypto once several cores are engaged.
- **AES-CBC is the specific villain: it is serial.** Each block depends on the
previous one, so the ARM AES instructions cannot pipeline across blocks. GCM
(CTR-based) and ChaCha20-Poly1305 both parallelise freely. That is why the
same UDM does 557 Mbit/s single-stream on WireGuard and only 240 on IPsec.
- **This retroactively vindicates the GCM cutover as the right idea aimed at the
right box** — GCM would have removed the serial dependency on the constrained
end. UniFi simply does not offer it, which is what made it impossible.
### Options this opens
- **AES-128 instead of AES-256: ~16–20% for free**, no topology change, one API
call per end. 128-bit is not the weak link here (SHA1 integrity is more
dated, and unchanged either way). Operator's call — **not adopted**, restored
to aes256.
- **WireGuard site-to-site via ana-wg: 767 Mbit/s single-stream** (3.1×), and it
sidesteps the UDM's IPsec datapath entirely. Still the biggest win available.
- Replacing the FortiGate **will not help this** — it was never the constraint.
Worth knowing before the cutover.
### State left behind
UDM network object verified **byte-identical** to its pre-test snapshot
(aes256/sha1). Tunnel up, selectors 1/1. FortiGate phase2 `pfi-ana-nh3` is
left as `aes256-sha1 aes256gcm aes128-sha1` — a permissive superset; the peer
offers only aes256 so the extra entries are inert, but **narrowing it back to
`aes256-sha1` is one line** if the looser list is unwanted.
---
## FOLLOW-UP 4 (2026-08-23): a downstream WireGuard terminator costs nothing to forward through
Operator's point: FortiOS has no WireGuard, so a WireGuard site-to-site must
terminate on a box *behind* the edge. Correct — and `ana-wg` (LXC, CT 113 on
pfi-pve, 10.250.50.252) already is that box.
**This closes a gap in FOLLOW-UP 3.** That 767 Mbit/s figure was measured with
traffic terminating *on* ana-wg. Real traffic must be forwarded onward to other
Anaheim hosts, which was never measured. Now it is:
| topology | 1 stream | 8 streams |
|---|---|---|
| IPsec, FortiGate ↔ UDM (today) | 245 Mbit/s | 692 Mbit/s |
| WG terminating **on** ana-wg | 767 Mbit/s | 763 Mbit/s |
| **WG transit: nh3 → wg → ana-wg → forward → ana-docker** | **763.8 Mbit/s** | **790.4 Mbit/s** |
**Forwarding through the LXC is free** (763.8 vs 767). The downstream-VM
architecture delivers the full 3.1× single-stream for real transit traffic, not
just for traffic landing on the tunnel box.
ana-wg while forwarding 764 Mbit/s: **~22% busy across 4 cores** (77.8% idle),
so roughly 0.9 cores. Note `/proc/loadavg` inside this LXC reports the *host's*
load, not the container's — do not read it as ana-wg's own. For contrast the
UDM burns 35.4% of its 4 cores to move 240 Mbit/s, so ana-wg has ample headroom.
### Design consequences of terminating downstream — the parts that need decisions
1. **Anaheim hosts must route to ana-wg, not to the FortiGate.** The 763.8
figure was obtained with an explicit `10.30.10.200/32 via 10.250.50.252`
route on ana-docker. Without that, a host sends 10.100.0.0/16 to its default
gateway (ana-gw), which routes it back out the *same* interface to ana-wg — a
LAN hairpin crossing the FortiGate twice. **The hairpin variant was NOT
measured.** Options: DHCP option 121 pushing the route fleet-wide, a dedicated
transit VLAN for ana-wg, or accept the hairpin.
2. **New single point of failure.** Today site-to-site dies only when the edge
dies, which is total anyway. A downstream terminator fails independently.
Mitigation: keep the IPsec tunnel configured as a higher-metric fallback
route so it takes over when ana-wg is down.
3. **ana-wg is an LXC on pfi-pve**, so its ~0.9 cores and NIC traffic land on the
hypervisor shared with the rest of the Anaheim VMs.
4. **The NH3 end needs a terminator too**, and there are two shapes:
- **Linux VM at NH3** (nh3-dev or a dedicated VM on nh3-pve) — this is what
was measured: **764 Mbit/s**.
- **NH3 UDM's existing WireGuard server** (`PFI-NH3-WG`, wireguard-server on
UDP 31337) accepting ana-wg as a peer — plausible but **untested**, and
UniFi's WireGuard shows a per-flow penalty (557 Mbit/s single-stream on
Site Magic), so expect ~557 rather than 764. Still 2.3× today.
### Standing recommendation
Worth doing, but it is **a project, not a config tweak** — routing, failover and
policy all need deciding. The cheap wins remain available meanwhile and are
independent: `nconnect=8` on NFS mounts (approved by brokkr-smithy-dev, pending
the FortiGate work settling) and AES-128 for ~20%.
---
## LANDED (2026-08-23): AES-128 on both tunnels; FortiGate public admin closed
Operator directed: adopt AES-128 on **both** Anaheim tunnels, make-before-break,
then close the FortiGate's WAN and SSH admin surfaces. All done and verified.
**Context that retires the WireGuard-in-a-VM design work:** the FortiGate is
being **replaced by OPNsense on a Dell R420**, which gives **WireGuard on the
edge device itself**. The downstream-terminator architecture (FOLLOW-UP 4) is
therefore moot — do not scope it. This also **un-parks the OPNsense migration**,
which auto-memory recorded as PARKED pending "hardware acquisition"; the R420
is that trigger.
### What changed
Make-before-break on the FortiGate first, so neither tunnel dropped waiting on
a far end:
| phase2 | proposal now |
|---|---|
| `pfi-ana-nh3` | `aes256-sha1 aes256gcm aes128-sha1` |
| `ana-eshudm-dyn` | `aes256-sha1 aes128-sha1` |
Then each UDM flipped to `ipsec_esp_encryption: aes128`:
| tunnel | UDM object | before | after |
|---|---|---|---|
| NH3 ↔ ANA | `pfi-nh3-ana` `697d64414c85dd2b6669b00a` @ 10.100.0.1 | 245 Mbit/s | **269.7** |
| ESH ↔ ANA | `esh-ana` `697723b9b9d4266dddf2bcc7` @ 10.0.0.1 | 268 Mbit/s | **304.3** |
Single-stream gain ~10–13% here, against 16–20% in the earlier controlled A/B —
the difference is live-link variance, not a different result. Both UDM objects
were diffed field-by-field against pre-change snapshots: **the only field that
moved on either is `ipsec_esp_encryption`.**
The FortiGate proposal lists were deliberately **left permissive** (still
accepting aes256). The peers offer only aes128 so the extra entries are inert,
and keeping them means a UDM reverting does not strand the tunnel. Narrowing to
`aes128-sha1` alone is a one-liner if the looser list is unwanted.
### Admin surfaces closed
`wan1 allowaccess` → **`ping`** (https + ssh removed) and `infra-ops` trusthost
→ **10.0.0.0/8 only** (the 8 wide-open ranges unset). Verified 443 and 22 closed
from both NH3 and ESH; management over the tunnel at 10.250.0.1 still works.
**Sequencing that matters: the close was executed over the TUNNEL path, not over
WAN** — removing `ssh` from allowaccess while connected over WAN kills the
session mid-command.
**Consequence to hold in mind: ana-gw now has no out-of-band management path.**
If both tunnels drop it is console-only until someone is on site.
### Gotcha: the two UDM vault items have DIFFERENT shapes
- `unifi/pfi-udmse-api-key` → a **bare 32-char key**. `secret get` output is the key.
- `unifi/esh-udmpm-api-key` → a **19-line documentation note** with the key on a
`key:` line. `secret get` piped straight into a header yields a 1396-byte
value and the UDM answers **`400 Bad Request` from nginx**. Extract with
`grep '^key:' | awk '{print $2}'`.
**The ESH key's first-ever confirmed WRITE happened here** (auto-memory recorded
it as read-verified only): a control PUT of the unchanged object returned
`rc:ok`, then the real change did too. That key has a full read+write admin role.
---
## CORRECTION (2026-08-23): port 80 on the WAN IP is the FortiOS ACME listener
The claim in the previous section that `.42:80` was an **ISP transparent proxy**
was **WRONG**, and so was the earlier warning that ACME renewal would fail with
port 80 absent from `allowaccess`. Operator pushed back asking where the port-80
map terminated. It terminates **on the FortiGate itself**.
**What it is:** the FortiOS **ACME HTTP-01 challenge listener**. `config system
acme` has `set interface "wan1"`, and FortiOS opens port 80 on that interface to
answer Let's Encrypt challenges **independently of `allowaccess`** — `wan1
allowaccess` reads `ping` only and the port is still open. Every non-challenge
request returns a fixed 403 whose body is literally:
```
<!DOCTYPE html><html><head><title>ACME Access Only</title></head><body>ACME Access Only</body></html>
```
**Not a DNAT.** The full VIP table has 14 entries; only two land on `.42` —
`Kokoro-In` (:8880 → 10.250.50.51) and `wg-to-ana-wg` (:31337 → 10.250.50.252).
~~Worth noting separately: four VIPs are all-port static NAT~~ — **that claim was
WRONG, see the correction below.** All fourteen VIPs are scoped.
### The methodology error that produced the wrong answer — worth not repeating
The sniffer filter used was `dst host 38.120.12.42 and tcp port 80`. **`dst host`
matches only inbound packets**, so outbound SYN-ACKs were excluded *by
construction*; concluding "the box sends no SYN-ACK" from that capture was
unsound. Re-run with the bidirectional `host 38.120.12.42 and tcp port 80` it
immediately shows `wan1 out 38.120.12.42.80 -> <scanner>: syn ack`.
**Rule: when testing whether a box *answers*, the sniffer filter must be
bidirectional. `dst host` silently answers a different question.**
### Consequences
- **ACME renewal will work** with `allowaccess ping`. The earlier "add `http`
back or the cert expires" warning is retracted — FortiOS opens the challenge
port itself. Cert valid to 2026-10-27, renewal attempt ~2026-09-27.
- **It is not an admin surface** — static 403, no auth, no GUI.
- Its practical value is now low: WAN admin is closed, so the cert only serves
the internal GUI at 10.250.0.1, where the name would not match anyway. Killing
it (`config system acme` → unset interface) would close the last WAN listener
at the cost of cert renewal. Operator's call; **not done**.
---
## CLOSED OUT (2026-08-23): ACME disabled; and the "all-port VIP" alarm was FALSE
### ACME disabled — the WAN IP now exposes nothing
`config system acme / unset interface` (the account object is left in place;
with no interface bound there is no listener). Verified:
- **External scan of 38.120.12.42 across 55 ports: no open TCP ports at all.**
- Internal GUI at 10.250.0.1 still answers **200**, SSH still works.
- `admin-server-cert` is still `ana-fw.pfi` — the existing cert is untouched and
serves the internal GUI until **2026-10-27**; it simply will not auto-renew.
Reverse with `config system acme / set interface "wan1"`.
### RETRACTION: the four VIPs are NOT all-port
A previous section claimed `Rustdesk`, `https-to-tacticalrmm`, `web-to-webhost`
and `web-to-sfcontainer` were unrestricted all-port static NATs. **They are not.**
A FortiOS VIP can be scoped **two different ways** and the parser used only
checked one:
1. `set portforward enable` + `set extport <n>` — a single mapped port, **or**
2. `set service "<svc>"` on the VIP object — constrains the VIP to that service.
All four use form 2. The custom services are narrow: `Rustdesk` = TCP
21115–21119 + UDP 21116 (the standard RustDesk range), `ssh-mapped-2223` = TCP
2223 only. **Every one of the 14 VIPs is scoped; none is unrestricted.**
**Lesson: absence of `portforward` does NOT mean all-port on a FortiOS VIP —
check `service` too.** Better still, do what settled it here: scan from outside
rather than reading config.
### Ground-truth public exposure (external TCP scan, post-change)
| IP | open | maps to |
|---|---|---|
| 38.120.12.41 | *nothing* | — |
| **38.120.12.42** | ***nothing*** | the FortiGate itself — fully closed |
| 38.120.12.43 | 80, 443 | sf-ana-container 10.250.150.100 (SureFire tenant) |
| 38.120.12.44 | 22, 80, 443, 8025, 21115–21119 | gitea (→222), traefik, mailrise, RustDesk |
| 38.120.12.45 | 80, 443, 2223 | pfi-ana-webhost 10.250.50.52 (2223→22) |
| 38.120.12.46 | 443 | pfi-tacticalrmm 10.250.50.57 |
Configured-but-closed: 8443 (mattermost-calls), 8444 (webdav-nas), 8880
(Kokoro-In) — VIPs exist, nothing listening behind them. Worth a tidy-up during
the OPNsense translation but not exposure.

# [2026-08-23] hrafn adopted; its CI deploy reported green while deploying nothing
`hrafn` — genuine-Chromium browser-fetch behind a REST API, for bot-gated sites
(Reddit first). Built by nevermore-claude on ana-docker, handed to infra-ops for
uptime ownership. Internal-only on `traefik-net`, no host port; consumers reach
`http://hrafn:8080`. Canonical at `stacks/hrafn/`.
## Intake found a live credential exposure
`/opt/docker/compose/hrafn/.env` was mode **0644 with a live 57-char bearer token**
— verified as real exposure by reading it as `nobody` on a box with four
interactive accounts. Tightened to 0600. That triggered the wider sweep (see
[[2026-08-23-ana-docker-env-perms-sweep]]).
## The CI defect — the one worth remembering
I authored the deploy (elway playbook + gitea workflow) to replace a hand-rsync,
tagging the image with the commit SHA for provenance. nevermore-claude later found
v1.0.0 deploying "green" while the host still served 0.1.0.
**Root cause was mine and nastier than either hypothesis.** The staging dir was
`$compose_dir/.stage` — **inside** the rsync target. So
`rsync -a --delete $compose_dir/.stage/ $compose_dir/` deleted `.stage` from the
destination (absent from the source listing) **during** the transfer, destroying
its own source mid-copy. Reproduced exactly:
```
before: app.py="OLD" leftover.txt .stage/app.py="NEW"
after: app.py="OLD" leftover.txt GONE, .stage GONE
```
Deletion succeeded, the copy silently did not, rsync exited 0. So the directory
*looked* converged while host source stayed frozen at the first manual rsync —
and because the build's `COPY` inputs never changed, Docker full-cache-hit and
every SHA tag aliased one image. **The provenance the tagging existed to provide
was false for the pipeline's entire life.**
**The real failure is the verification.** The verify steps asserted the marker,
container health, and a 200 from `/readyz` — all of which pass against a
completely frozen host. None measured *content*. A deploy that reports success
without asserting the bytes changed is verifying an **uptime**, not a deploy.
## Fixes
- stage at `/tmp/hrafn-deploy-stage`, outside the target
- CI computes `context_sha256` over the shipped file list; the playbook recomputes
it **on the host after the converge** and fails on mismatch
- compare the running container's `src/**/*.py` against the host's, so a SHA tag
cannot name layers the image lacks
- **compare `*.py` only** — `pip install .` generates `src/*.egg-info/*` inside the
image and `__pycache__` appears at runtime, so a naive `find src -type f` compare
false-fails on every healthy deploy. Verified against a known-good container
before shipping (12 host files, 18 in container, 0 content differences).
- declined `--no-cache`: a cache hit is *correct* when the context is genuinely
unchanged; assert the property rather than brute-force it.
## Access
Operator granted claude-bot **write** on `vh/hrafn`, so infra-ops maintains the
pipeline it owns instead of routing patches through the repo holder. `vh/hrafn` is
canonical; `stacks/hrafn/ci/` is a verified mirror.

# [2026-08-23] selene seat retired after losing a head-to-head; 7 aliases share one seat
## Why selene went
Benchmarked against `gen` on selene's own job — 24 designed judge items with
checkable ground truth, pairwise + absolute modes, 3 repeats, run on **both** a
neutral JSON prompt and Selene's **native Atla template** (288 calls, free local).
```
neutral JSON selene 20/24 (83%) gen 23/24 (96%)
native Atla selene 21/24 (88%) gen 22/24 (92%)
```
gen won on both templates and **selene's best sat below gen's worst**. Selene was
given its own fine-tuned template as a fairness check before any recommendation;
it gained one point, not three.
**Decisive defect: selene cannot emit "tie"** — 0/2 on both templates, forcing a
winner on every equivalent pair. For eval work that is the case that matters.
brokkr-smithy-dev independently corroborated from the other end with a **null
control** (an excerpt compared against ITSELF, where tie is definitional):
`chat-judge`(selene) TIE **27/60 = 45%**, gen **60/60 = 100%**; ground-truth
recovery on real-corpus ranking selene **47% — chance** vs gen 94%. My 83-vs-96
understated it: on a *ranking* task selene was a coin flip. Absolute scoring on
designed items is an easier task than ranking real text — the harness is a
**screen, not a verdict**, and its README says so.
Reclaimed **17.2 GiB** on ana-ml2 GPU1 (free 1,818 -> 19,450 MiB).
## The naming rule, restated the hard way
I proposed repointing `selene-1-mini-8b` at gen and was **correctly overruled**:
> never repoint a named model at a different model's endpoint — that is
> intentionally misleading
`chat-judge` is a **role** alias (ADR-0012: consumers bind the capability) and
moved to gen with a deterministic judge profile copied from `image-judge`.
`selene-1-mini-8b` is a **model** name and was removed outright — it now returns
`HTTP 400 Invalid model name`, verified. The discriminator: *does the string
promise a capability, or an identity?*
## The 7-way alias collision — the finding with the longest reach
```
chat-judge classifier gen image-judge
qwen-image-bench summarizer summarizer-large -> qwen3.8-27b-uncensored :8015
```
Also colliding: `gen-frontier`/`gen-frontier-reasoning`/`glm-5.2`/`glm-5.2-reasoning`;
`ext-tts`/`gpt-4o-mini-tts`/`tts-1`/`tts-1-hd`; `reranker`/`reranker-a3-bge-v2-m3`.
**Cross-checking a result against another alias measures nothing when they are the
same weights — agreement is an echo, not corroboration.** Documented at the head of
`model_list` in the live gateway config, because it belongs where people read it.
This caught a real defect within hours: brokkr's R47 premium-corpus gate was about
to run ~46,000 record-exposures against `gen` with `summarizer` shortlisted as an
independent second opinion. They pinned the backing model in the preregistration
and dropped the second-alias idea instead.
## Provenance seam (brokkr's pushback, adopted)
The gateway returns the **alias** in the response `model` field, not the backing
model — so a per-call guard catches a swap *during* a run and is blind to one
*between* runs. **Role alias for routing, concrete model for provenance.**
`GET :4000/model/info` with the shared key already exposes backing model +
api_base; resolve at run start AND end and void on mismatch.
## Artifacts
- Harness kept at `tools/judge-bench/` (`--models` REQUIRED — a stale default
would silently benchmark a retired seat).
- `stacks/selene/` keeps compose + a README explaining the retirement.
- Technique worth stealing, from brokkr: **a control constructed so the correct
answer is DEFINITIONAL rather than judged cannot inherit the designer's error.**
Item vs itself; response vs its own truncation; text vs its own clauses
permuted. Add those before adding more judged items.

# [2026-08-23] `/mnt/smithy` mounted on ana-ml2 — read-only and SOFT, deliberately not matching nh3-dev
brokkr-smithy-dev asked for `10.100.50.50:/volume1/smithy` on ana-ml2 to run R47's
CPU-bound corpus pipeline on 96 idle EPYC cores instead of one nh3-dev vCPU. Granted,
with two deliberate deviations from what was requested.
```
sudo mount -t nfs4 -o ro,soft,timeo=30,retrans=3,proto=tcp,vers=4.1 \
10.100.50.50:/volume1/smithy /mnt/smithy
```
The export already permitted ana-ml2 — no DSM change needed. Write is genuinely
refused.
## Why soft, not hard
They asked to match nh3-dev's mount, which is `hard`. **nh3-dev is same-site as the
NAS; ana-ml2 is not** — this is cross-site NFS on the box running the fleet's
inference seats. A hard mount turns a link blip into unkillable D-state, and this
fleet has already lost a host that way (esh-docker-vm; only fix was a reboot). Soft
returns EIO, the batch job fails, you rerun it. The soft-mount corruption caveat is a
**write** hazard and this is read-only. Mirrors the existing ESH books mount.
## Why not in fstab
Manual only, matching irv-ml1's `/mnt/smithy` precedent. A cross-site NFS entry in
fstab can hang boot on a GPU host with 71 days uptime. **Needs remounting after a
reboot.**
## The performance reality, measured on the same file through the same mount
```
ana-ml2 (cross-site) nh3-dev (same-site)
sequential read 24.7 MB/s 98.3 MB/s
small-file rate 45.3 files/s 34.6 files/s
```
Two different stories, and file layout decides which you get:
- **Many small records -> ana-ml2 wins on BOTH axes.** That path is bound by per-file
round-trips and NAS overhead, not bandwidth, and ana-ml2 is an idle 96-core box
while nh3-dev is a loaded 16-vCPU VM.
- **Bulk sequential streaming -> the link eats the win.** 4x read penalty against a
6x CPU gain. `datasets/raw` is 126 GB, `datasets/derived` is 1.7 GB — which one the
pipeline traverses changes the answer by two orders of magnitude. Staging a subset
to ana-ml2 local disk (195 GB free) beats pulling it over the wire repeatedly.
The 24.7 MB/s is the Anaheim tunnel, not NFS and not the NAS — see
[[2026-08-23-anaheim-ipsec-tunnel-ceiling]]. No mount tuning will move it;
parallelism will.

# [2026-08-23] Worldtree b187 shipped; all three instances de-armed from a 69-day-stale `:latest`; Matrix homeserver re-plumbed
## b187 pre-stage (#405 phases 1+2)
The matrix bridge stopped embedding the engine and became an HTTP client of the
Conversation API, so `WORLDTREE_API_URL` became **boot-blocking** — absent from the
container env, the bridge exits by design. Demo's compose never passed it; the next
recreate would have crash-looped. Pre-staged on demo and personal (additive, backed
up, verified with `docker compose config`, nothing restarted).
**Key decision, and I got its scope wrong first.** I argued demo should stay keyless
(no homeserver -> no rooms -> no turns -> no 401s). Right about turns, **wrong about
scope**: the engine preflight authenticates at boot regardless of homeserver, so demo
booted permanently degraded. Corrected — key `341c1488` minted under worldtree-dev's
recorded authorization, vaulted, wired, three-hop hash-verified.
## The 69-day-stale `:latest` landmine
All three instances pinned `WORLDTREE_IMAGE=.../worldtree:latest` in `.env` while
running SHA-tagged images built that day. Local `:latest` = `b19afd71d7cc`, built
**2026-06-14**. So ANY `docker compose up` — anyone's, for any reason — silently
downgraded that service by 69 days. Same footgun as the 2026-06-15 outage.
Re-pinned all three to their running SHAs (Worldtree #410), verified by rendering
compose config rather than reading `.env`, containers untouched. Playbook at
`playbooks/repin-worldtree-image.yaml`.
**`worldtree-pinned` was the worst case:** the instance whose entire purpose is being
frozen was running a **dangling image with no repo tags**, kept alive only by the
running container. One `docker rm` from garbage collection. Tagged
`:446e5807bf43` first, then pinned.
The guard I wrote had two bugs the pinned case exposed: it compared the container's
`.Config.Image` **string** (only the tag it was CREATED from — pinned was created
from `:latest` back when that meant 446e5807), and it reported CHANGED
unconditionally. Now compares **image IDs** and skips when already correct.
## Matrix homeserver ownership
Operator ruled: **personal owns the Matrix bridge.** The appservice tokens were never
missing — both sat at length 64 in the vaulted dev `env.sh` while both deployed
instances had them at length **zero**. Someone wired four of six Matrix vars and
stopped. Wired them into personal, three-hop verified.
**The trap worth remembering:** Synapse's registration pointed at
`http://10.100.10.50:8009` — nh3-dev, a dead epoch, with transaction 2801 queued at
512s backoff. The natural fix (swap the IP) gives `10.250.50.152:8009` which is
**DEMO's** bridge, and Synapse can reach both — it would have connected, delivered,
and looked correct while routing the operator's live rooms to the demo instance.
**Personal's bridge is :8010.** `docker port` is ground truth.
Corrected the URL, restarted Synapse (healthy in 32s after 3.5 months up), verified
`GET /_matrix/app/v1/ping -> 200` from inside the Synapse container. worldtree-dev's
smoke passed first try: room created, mimir accepted the invite, a real engine turn
ran, mimir replied in persona voice. #408 closed.
## Open on worldtree-dev's side
- **#411** — personal's bridge logs `Debug sink init failed: Permission denied:
/app/sessions/debug_rooms.json`. It creates two debug rooms but cannot persist
their IDs, so **every restart mints a fresh pair on the live homeserver**. Room
litter that compounds silently. Needs a which-container-writes-what check on the
sessions volume before anyone chowns it.
- Bridge/engine agent-roster drift: 6 of the bridge's 9 configured agents are not
listed by the engine on either instance.
- Historical Domari pairwise verdicts from the selene era are coin-flip-grade
(see [[2026-08-23-selene-retired-alias-collision]]); worldtree-dev banked that so
no future arc leans on them without re-judging.

# [2026-08-24] ana-gw public admin surface closed to zero, ACME listener included
WAN admin was opened at the start of the session as a cutover contingency
("so I don't have to drive down there"), then closed again on operator
instruction once the AES-128 work landed. Net result: **the FortiGate's WAN
address now exposes no TCP port at all.**
## Final state
External scan of `38.120.12.42`, 55 ports: **nothing open**. Verified from two
sites. `wan1 allowaccess` = `ping`; `infra-ops` trusthost back to `10.0.0.0/8`.
**Consequence to hold: there is no out-of-band path to ana-gw.** If both tunnels
drop it is console-only. Re-open is two one-liners (allowaccess + trusthost) —
both are recorded in auto-memory `reference_fortigate_ana_gw_access`.
## Port 80 was the FortiOS ACME listener, and I got it wrong first
`38.120.12.42:80` answered a bare 403 (`ACME Access Only`, 101 bytes) with
`allowaccess` set to ping only. First diagnosis — "an ISP transparent proxy" —
was **wrong**, and the reason is worth keeping:
> The sniffer filter was `dst host 38.120.12.42 and tcp port 80`. **`dst host`
> matches inbound only**, so outbound SYN-ACKs were excluded *by construction*,
> and concluding "the box sends no SYN-ACK" from that capture was unsound.
Re-run bidirectionally (`host … and tcp port 80`) it immediately showed
`wan1 out 38.120.12.42.80 -> <scanner>: syn ack`. **Rule: to test whether a box
*answers*, the filter must be bidirectional.**
The listener is opened by `config system acme / set interface "wan1"` and
**bypasses `allowaccess` by design** — FortiOS needs port 80 for HTTP-01. It
was disabled (`config system acme / unset interface`); the LE cert (`ana-fw.pfi`,
valid to 2026-10-27) is untouched and simply stops renewing, which is fine
because WAN admin is closed and the box is being replaced.
## Retracted in the same pass: the "four all-port VIPs" alarm
Claimed four VIPs were unrestricted all-port static NAT. **False.** A FortiOS
VIP is scoped **two** ways — `portforward`+`extport`, *or* a `service` binding
on the VIP object — and only the first was checked. All 14 VIPs are scoped;
`Rustdesk` is TCP 21115–21119, `ssh-mapped-2223` is TCP 2223 only.
Ground-truth external scan of all six public IPs is recorded in
`reference_fortigate_ana_gw_access`. Configured-but-dead: `:8443`
(mattermost-calls), `:8444` (webdav-nas), `:8880` (Kokoro-In) — tidy-up
candidates for the OPNsense translation, not exposure.
**Lesson, twice in one session: measure from outside instead of parsing config.**
Both wrong answers came from a filter that answered a different question.

# `[2026-08-24]` char-rp seat: OOM root-cause, Gemma-4 MoE swap, and the abliterated trainee base
One evening, one thread with brokkr-smithy-dev, five commits: `850e0c3`,
`27155c0`, `f509668`+`24e8826`+`1bd90ea`+`3446367`+`8d6a939`, `14ff4a3`,
`019ccff`, `5415fd4`.
## 1. The seat was crash-looping, and the cause was NOT its config
`vllm-meromero-rp` reported up-but-unreachable, RestartCount climbing (13 by the
time it was examined, not the 4 first reported). Startup logs looked clean all
the way through weights, `torch.compile` and CUDA-graph capture, then:
torch.OutOfMemoryError: CUDA out of memory. Tried to allocate 336.00 MiB.
GPU 0 has a total capacity of 94.97 GiB of which 195.19 MiB is free.
**⚠ `--gpu-memory-utilization` SIZES THE KV CACHE AND DOES NOT COVER CUDA
CONTEXT, GRAPHS OR NON-TORCH OVERHEAD.** gen is configured at 0.43 and actually
held 45.6 GiB. char-rp was at 0.51. The pair was committed to 0.94 of the card
with ~0.6 GiB of real headroom — it fit on the 21st and stopped fitting on the
24th.
Dropped char-rp to 0.47: ~4.8 GiB margin, KV 27.36 → 23.56 GiB, 430,825 →
371,023 tokens against a max-model-len of 262,144. **Cost nothing usable** — the
pool still holds 1.4x a full-length sequence; what is lost is concurrent long
requests, not context.
**⚠⚠ THE MISSING HALF, found later that evening: gen's footprint GROWS WITH
UPTIME.** Same container, same 0.43: **45.6 GiB after ~3 days up, 38.5 GiB
freshly restarted** — ~7 GiB apart. Nothing about char-rp changed between the
21st and the 24th; *gen crept up underneath it*. **Headroom arithmetic done
against a long-running gen is measuring a moving number.** Measure against a
freshly-restarted one.
## 2. `char-rp` and `char-rp-reasoning` are ONE seat, not two
Both LiteLLM routes point at `10.250.50.54:8016/v1` — `hosted_vllm/char-rp` and
`hosted_vllm/char-rp-thinking`. brokkr had reported 30/80 and 80/80 failure
rates as two failing services; it was one outage sampled twice. This also
*improved* a result of theirs: their CoT on/off battery had assumed both aliases
were the same weights under two chat templates, and the routing detail turned an
assumption into a verified fact.
(`vllm-charrp-reasoning-nvfp4`, the Heretic2 NVFP4+MTP container, has been
stopped for 12+ days and is unrelated — it is not what that alias resolves to.)
## 3. The seat swapped to the Gemma-4 26B-A4B MoE
Operator-directed straight-across replacement: same port, same
served-model-names, so no gateway route or consumer config moved. Rationale is
throughput under CoT — the user waits through the whole reasoning block before
the first visible token, and the MoE measures ~114 tok/s @32K against the dense
31B's ~40.7.
Serving copy is `RedHatAI/gemma-4-26B-A4B-it-NVFP4` (16 GB), chosen over the
other `-it` quants because it is compressed-tensors (`nvfp4-pack-quantized`) —
the same loader path the outgoing seat used. Smaller weights at the same 0.47
budget bought **1,724,110 KV tokens against the predecessor's 371,023**.
`meromero-charrp` is retained stopped in `created` state, labelled
`AI - Dormant`. Both stacks bind `:8016`, so rollback is **stop-then-start**.
## 4. ⚠ THE STALE-CHAT-TEMPLATE TRAP IS ENDEMIC, NOT A ONE-OFF
Verified by hash across every third-party Gemma-4 derivative pulled:
| build | lines | sha256 (normalised) |
|---|---|---|
| upstream `google/gemma-4-26B-A4B-it` | 390 | `6a1015c47ccfcfa6` |
| RedHatAI NVFP4 (served) | 389 | `6a1015c47ccfcfa6` — the only match |
| llmfan46 heretic | 365 | `0a52be69cda5ab8a` |
| TrevorJS abliterated | 266 | `58c66fdee4afa297` |
| jenerallee78 abliterated | 266 | `58c66fdee4afa297` |
| prithivMLmods NVFP4A16 | 266 | `58c66fdee4afa297` |
Three independent repos carrying the *identical* stale file means it propagated
through the ecosystem. Consequences differ by use and **both are silent**:
serving a mismatched template renders a different prompt; **training through
`base/chat_template.jinja` means training on a different prompt format than
production serves** — train/serve skew, no error, presents as a tuning failure.
The production compose now pins the template explicitly. It is a **no-op for the
served weights** (the A4 build ships that exact file) and permanently closes the
class. ⚠ If `GEMMA4_MODEL` ever points at a different checkpoint, the template
default must move with it.
## 5. A benchmark result was RETRACTED — below chance indicts the instrument
A battery appeared to show Gemma at **12% contradiction detection with CoT off
against gen's 81%**. An A16 activation-precision control was staged to test
whether the quant scheme owned it. Then the operator asked to see the individual
items, and the item was **ill-posed**: it presented two mutually contradicting
statements and asked for "*the* contradicting statement", but **contradiction is
symmetric**. The model consistently named the absolute claim — a defensible
reading the labelling scored wrong every time.
**⚠ THE TELL WAS IN PLAIN SIGHT: 12% ON A FIVE-OPTION TASK IS BELOW THE 20%
CHANCE FLOOR.** A below-chance score indicts the instrument before it indicts
the model, and neither side reacted to it. I spent the afternoon verifying repo
names, config fields, template hashes and tokenizer vocabs — every layer of
plumbing — and never asked whether the number itself was *possible*. **A
preflight can be thorough and still be aimed in the wrong direction.**
Retracted: "the model owns the contradiction deficit"; "domain tuning costs 43
points of contradiction detection" (on a sound instrument it **reverses**); all
pre-fix T2 numbers. Recorded as a dated superseded-claims table in
`stacks/gemma4-charrp/README.md` rather than a silent edit.
**What survived:** the A16 control result — activation precision is close to free
on this battery, every other task identical across W4A4 and W4A16 builds.
## 6. The abliterated trainee base — measured, not assumed
Operator directed a low-damage abliterated instruct build. "Low damage" was
treated as a measurable claim; the field spreads from KL 0.09 to 0.4118:
| build | method | KL | refusals |
|---|---|---|---|
| **llmfan46** (operator's pick) | Heretic v1.2.0 ARA | 0.1237 | 3/100 |
| TrevorJS | ARA-family | 0.09 | 1/100 effective, 5/686 cross-dataset |
| jenerallee78 | ARA 2-pass | 0.1299 | 7.7% StrongREJECT |
| huihui-ai | remove-refusals | none published | none published |
Fleet anchor: our own work found **Heretic at KL 0.12 preserved the MTP head at
83.7% acceptance**, so both staged builds sit inside an already-measured band.
huihui-ai rejected — no metrics, its card calls the method "a crude,
proof-of-concept implementation", it abliterates both thinking and non-thinking
modes, and its parameter count runs ~738M over upstream. Operator's independent
read matched ("huihui produces garbage").
**Abliteration isolated properly** (stock BF16 vs llmfan46 BF16, same precision,
same pinned template, same 192 items):
T2 contradiction 75% → 59% (−5 items)
T6 spatial 75% → 88% (+4 items)
core 90.0% → 89.4% (−0.6 pts)
**It MOVED capability rather than removing it** — five lost on contradiction,
four gained on spatial, nearly cancelling. Nobody predicted a gain. **llmfan46
stands**; no case for re-staging on TrevorJS over 0.6 points.
⚠ Read as ~5 and ~4 items at n=32, not as −15.6/+12.5 percent. ⚠ Says nothing
about quantization — the stock-NVFP4 T2 figure came from n=16 against n=32,
different item sets, n-confounded.
## 7. ⚠ The production compose hardcodes `--quantization compressed-tensors`
Pointing the char-rp stack at unquantized BF16 weights crash-loops immediately:
TypeError: CompressedTensorsConfig.__init__() missing 3 required
positional arguments: 'target_scheme_map', 'ignore', 'quant_format'
vLLM trying to read a quantization config out of a checkpoint that has none. 35
restarts before it was caught. Hence `stacks/gemma4-trainee-bench/` — a separate
ephemeral stack with no quantization flag, `restart: "no"` so a bench seat cannot
resurrect itself and block gen's restore, and no homepage labels so it leaves no
permanently-offline card. That detour is why a base swap is now ~5 minutes
instead of ~15.
## 8. BF16 cannot coexist with gen
48.07 GiB of BF16 weights plus gen's footprint exceeds the 94.97 GiB card before
a byte of KV cache. Every BF16 bench window means **gen is stopped**. Two such
windows were run and gen restored both times; the restore was triggered by
observing the seat's own throughput logs (a large prefill burst then zero
running/zero waiting) rather than waiting on a courtesy message.

# [2026-08-24] ESH DNS fixed at the IPv6 layer, and the naming scheme went live
Reported as "`scriberr.ana.internal` doesn't resolve on my Mac, and nslookup
shows an IPv6 DNS server." Operator's diagnosis was right; the fix took three
wrong turns worth recording.
## Root cause
`esh-userland` has IPv6 PD with RA at `pref high`, and the UDM advertises
**itself** as the resolver via RDNSS. macOS honours RDNSS and prefers it over
the DHCPv4-supplied resolver, so queries went to the UDM — which does not know
`.internal` — and returned NXDOMAIN. AdGuard was never consulted.
Two adjacent gaps found while there: `esh-userland`'s **secondary** v4 resolver
was `10.0.10.1` (the UDM itself), and `esh-server` had **DNS handout disabled
entirely**, so every host there got the UDM and could never resolve `.internal`
— esh-docker-vm was living proof.
## The three wrong turns
1. **`dhcpdv6_dns_auto=false` alone does nothing.** It is only honoured **when an
explicit server is supplied**. Setting it bare looks like a no-op and invites
the conclusion that the field is inert — which I drew, wrongly. Despite the
`dhcpdv6_` prefix it *does* drive the RA's RDNSS option on a SLAAC network.
2. **`wan_dns1` is NOT used by the UDM's LAN-facing forwarder.** Setting it to
AdGuard persists, reads back, and changes nothing. Proven with **fresh
uncached ad domains** — AdGuard blocklists answer `0.0.0.0`, the UDM returned
real IPs. Reverted.
3. **`force-provision` returns `rc:ok` and proves nothing** — consistent with the
known `cmd/devmgr` behaviour.
Every failed attempt returned `rc: ok`. **Verify by observed effect.** RAs were
probed with a stdlib raw-socket Router Solicitation parsing option type 25
(`rdisc6`/`tcpdump` were both absent; nothing was installed).
## What landed
RDNSS **redirected** rather than disabled — better than switching it off:
| VLAN | v4 | v6 RDNSS |
|---|---|---|
| `esh-userland` | 10.0.50.45 + 10.100.50.40 | `…:4411:b105:50:45` |
| `esh-server` | 10.0.50.45 + 10.100.50.40 | `…:4411:b105:50:45` |
The v4 secondary moved from the UDM to the **NH3 AdGuard** — reachable over
Site Magic and authoritative for the zone. ⚠ **A secondary only fails over on
SILENCE, not on wrong answers**: NXDOMAIN is a *successful* answer, the client
accepts it and never retries. A secondary that doesn't know your private zone is
a coin flip, not a spare tyre. `esh-cameras` deliberately untouched — routing
camera DNS through AdGuard's filtering risks their cloud features.
## The naming scheme became real
The resolver address is the scheme's first live use, replacing a MAC-derived
SLAAC address that would break on a NIC change. All three `esh-server` Linux
hosts now carry `4411:B105` ("FOR ALL BIOS"):
```
esh-docker-vm …:4411:b105:50:45 esh-pve-nas …:4411:b105:50:55
esh-vm-db …:4411:b105:50:60
```
Applied by an `if-up.d` hook that **derives the prefix at runtime** (self-heals
on re-delegation), backgrounds itself with a retry (SLAAC may not have landed;
a blocking hook would stall bring-up on a headless box), and adds nothing to
existing config. **Not** an `iface … inet6 static` stanza — on Debian that sets
`accept_ra=0` and would strand the host.
⚠ **Proxmox bridges need `accept_ra=2`.** `esh-pve-nas` had link-local only
despite every sysctl looking right: `vmbr0.forwarding=1`, and the kernel ignores
RAs on a forwarding interface unless `accept_ra` is explicitly `2`. Fixed with
`accept_ra_defrtr=0` alongside, so it takes the prefix but **declines the default
route** — an IPv6 identity with no change to a hypervisor's routing. Expect this
on every Proxmox node when its LAN gets v6.

# `[2026-08-24]` Homepage: remote-label consumption re-verified, then the board relaid out on a uniform grid
Prompted by the operator: *"Homepage on esh-vm-docker lists remote dockers and
can absolutely consume their labels, please verify again. I am still
unsatisfied with the layout and aesthetics."*
## The verification — the operator was right, and the record now says so
**Homepage on `esh-docker-vm` discovers services by container label from all
five Docker engines in `conf/docker.yaml`, not just its own.** This is not an
inference; `GET /api/services` returns every card's `server` field, and the
2026-08-24 snapshot resolves to:
| `server` | host | label-discovered services |
|---|---|---|
| `ana-pfi-docker` | 10.250.50.70 | 30 |
| `irv-ml1-docker` | 10.100.79.3 (over WireGuard) | 15 |
| `ana-ml2-docker` | 10.250.50.54 | 14 |
| `esh-vm-docker` | 10.0.50.45 (the dashboard's own host) | 13 |
| `nh3-pfi-docker` | 10.100.50.40 | 2 |
**74 of 107 cards are label-discovered, and only 13 of those come from the
dashboard's own engine** — the other 61 are read off four remote hosts,
including irv-ml1 across the WireGuard tunnel. The remaining 33 carry
`server: null`: those are the manual `services.yaml` entries — hardware, BMCs,
hypervisors, printers, and user-level systemd services that have no container
to label in the first place. **That null is the only thing "not label-driven"
about this dashboard**, and it is a property of the entry, not of the host it
points at.
⚠ If a future session doubts this again, the check is one command and takes two
seconds — do not reason about it from the docs:
```bash
curl -s http://10.0.50.45:5100/api/services \
| jq -r '.[].services[] | .server' | sort | uniq -c
```
## What was actually wrong with the layout
Measured with Playwright against the live board (per-group `card=` width, card
height spread, and a geometric title-vs-status overlap test), not judged by
eye:
- **Card width changed at every group boundary.** `columns:` is not a density
dial — it sets `lg:grid-cols-N` for one group, so it fixes that group's card
width. Notes rendered a single **1464px** card; News and Media **728px**;
Eval & Retrieval **286px**; everything else 360px. Scrolling the page, the
grid resized five times.
- **Long names printed underneath their own status pill.** Measured by
re-injecting the old rule and testing the title text node's box against the
status cluster's box: **6 cards, all on the AI tab** — 3 in Inference, 2 in
Dormant, 1 in Eval & Retrieval; zero on the other three tabs, which is why
it survived earlier passes. Root cause is a genuinely counter-intuitive one:
the rule reserved a
78px gutter with `padding-right` and relied on `overflow: hidden` to hold it,
but **overflow clips at the padding box, not the content box** — so the
reserved gutter was spill room the title rendered straight through. The
intended `text-overflow: ellipsis` never fired either, because the ellipsis
is painted by whichever block's own line overflows, and here that is the
anonymous box around the bare title text node, which does not carry
`overflow`.
- **`AI Systems` / Scriberr was on all four tabs** — the 2026-08-18 UltraSeedbox
bug recurring, this time arriving from a container label rather than from
`settings.yaml`.
- **Icons were grey smudges.** Homepage masks every glyph over
`--color-logo-start/stop`; stock slate-400 → slate-700 sinks the bottom half
of each icon into the card fill.
- Bookmark groups and Jellyfin's trailing stream rows were the two components
the theme had never reached.
## The fixes
`stacks/homepage/conf/settings.yaml` — **all 20 groups to `columns: 4`.**
`stacks/homepage/theme/australis.css.in` → rebuilt → `conf/custom.css`:
gutter held by wrapping, description clamped to 3 lines (floor still 2), icon
ramp overridden, bookmark + trailing-widget components themed, group gap
10px → 22px. `stacks/scriberr/compose.yaml` — `homepage.group` → `AI - Audio
Tools`, container recreated on ana-ml2.
After: **every group renders at card=360**, and the collision count is zero.
Before/after, all four tabs: `http://10.100.10.50:8090/b/homepage-relayout/`
(24h TTL; also on the standing link board).
## ⚠ Three traps worth carrying forward
1. **"Columns = member count" is RETIRED** (it was the 2026-08-18 rule). It was
avoiding dead cells in a short last row and bought a worse defect. A short
last row is what a grid looks like; a card wider than its neighbours is what
a mistake looks like.
2. **A `:root` override of a Homepage theme variable is silently ignored.**
Homepage sets `--color-logo-*` on `.theme-slate`, and that class is on the
`<html>` element — the same element `:root` matches. `.theme-slate` (0,1,0)
beats `:root` (0,0,1), so the override does nothing and looks like the
variable is not the one in play. `html[class]` (0,1,1) wins, and does not
hard-code which `theme-*` class is active. Specificity alone is not enough
either: a custom property resolves from the *nearest* ancestor that sets it,
so the override has to land on `<html>`, not on `<body>`.
3. **The post-recreate tab-bar loss is INTERMITTENT, not guaranteed.** The
2026-08-19 note reads as though every recreate costs up to an hour of broken
render. This recreate came up correct within 10 seconds — fresh payload on
the first poll, all four tabs clickable a minute later. Recreate, *check*,
and only then walk away if it is actually in the broken state.
Also re-confirmed, since the change depended on it: **a `settings.yaml` edit
needs a container recreate, not a restart.** `docker restart homepage` left the
old `"columns":1` payload embedded in the served HTML with the correct file
mounted and readable inside the container; `compose up -d --force-recreate`
cleared it immediately.
## Deliberately not done — operator's call
The Main tab still opens on three sparse bands: **Notes** (1 member) and
**Games** (1) each burn a full 4-wide row, and **News** has 2. Merging Notes +
News, or folding Games into Apps, would tighten the top of the page — but that
is information architecture, not layout, and the group names are the operator's.
Surfaced rather than done.
→ **Resolved in pass 2 below**, where the operator delegated the naming
("re-categorize however you want"). Notes + News became `Daily`, Games folded
into `Apps`, and the `AI - Audio Tools` placement in this pass was superseded
(Scriberr moved on to `AI - Studios`).
---
# `[2026-08-24, pass 2]` Recategorised on "do I open this?", API groups collapsed
Operator, after seeing pass 1: *"You can re-categorize however you want.
service networking tab is uneven, you can split out the adguard cards, etc.
most of the issues are that tools I use and have a UI are interspersed with API
endpoints which are largely informational only. They might even go in their own
cards or start collapsed."*
## The axis
Every group is now either **tools** (expanded, top of tab) or **endpoints** (an
API, a broker, an agent — `initiallyCollapsed: true`, bottom of tab). A
collapsed group still renders its eyebrow and rule, so presence costs one line
instead of two rows.
Second, quieter rule that fell out of the same pass: **a group's members should
all carry a widget or none should.** A stat strip adds ~50px, so one widget card
in a row of plain ones opens a void under the plain ones — which is most of what
made the 13-member `Service Networking` band look broken.
## Shape
- **Main** — `Daily` (Memos, Miniflux, Nevermore, SearXNG — replaces the
1-card Notes and 2-card News bands), `Monitoring`, `Apps` (12; absorbed the
1-card `Games` band), `Media`, `UltraSeedbox`.
- **AI** — `AI - Gateways & Chat` (8) and `AI - Studios` (6) expanded; then
`AI - Inference` (7), `AI - Eval & Retrieval` (4), `AI - Speech (TTS)` (4),
`AI - Audio Tools` (2), `AI - Dormant` (6) all collapsed.
- **Toolchain** — `DNS & Filtering` (3), `Reverse Proxies` (2),
`Compose Consoles` (5), `Toolchain` (3), `Agents (no UI)` (6, collapsed).
- **Infrastructure** — unchanged; every card there is already a console.
Measured after: every group `card=360`, and `DNS & Filtering` and
`Reverse Proxies` both `h=134..134` — dead flush.
## ⚠ The move that made it affordable
**The sixteen GPU-backed model seats were NOT relabelled.** `homepage.group` is
read at container **creation**, so renaming `AI - Inference` to something
clearer would have meant recreating six vLLM seats plus four eval seats plus
four TTS engines — multi-minute model reloads on endpoints peers reach through
the gateway. Order plus `initiallyCollapsed` buys the same separation for free,
so the names stay ugly on purpose. **Do not spend that recreate on a label.**
28 containers *were* relabelled — all cheap web services — via five rerunnable
elway playbooks, `playbooks/homepage-regroup-<host>.yaml`. The canonical
`stacks/` tree was synced to match afterwards, so intent and reality agree.
`initiallyCollapsed: true` is a per-group key in `layout:`; confirmed present in
this build (`defaultOpen: !(group?.initiallyCollapsed ?? global)` in
`/app/.next/server/pages/index.js`).
## AdGuard (ANA) gained its widget, and the credential is fleet-wide
It was the only AdGuard without a query/blocked/latency strip, so it sat short
beside two tall siblings. **One `infra-ops` AdGuard login authenticates against
all three instances** (ANA `:8053`, NH3 `:8080`, ESH `:8080` — all returned 200
on `POST /control/login`, verified 2026-08-24). Vaulted at
`secret get nh3-dev/adguard-infra-ops-password`; written to
`/opt/docker/compose/adguard-ana/.env` (0600, root) and never into git. Its icon
was also the odd one out (`mdi-dns` against two `si-adguard`).
## ⚠⚠ `initialSettings":{}` — the tab-bar mystery is a SWALLOWED EXCEPTION
The biggest durable finding of the day, and it cost ~25 minutes. Full write-up
in `stacks/homepage/README.md`; the short version:
`initialSettings":{}` in the served HTML is **the catch branch** of the page's
data loader, not a warm-up and not a cache. And the error can vanish without
trace: the logger is assigned as the first statement *inside* the same `try`,
and the `catch` only logs `if (logger)`. If the logger is what threw, nothing is
written anywhere — which is exactly what was observed.
Ruled out by measurement, do not re-run: `/api/services`, `/api/bookmarks`,
`/api/widgets` and `/api/hash` all return **200 with correct content** while the
page serves `{}`; restoring the previous known-good `settings.yaml` reproduces
it identically; `/api/validate` returns `[]`; disk and permissions are fine.
**One-command test:**
`curl -s http://10.0.50.45:5100/ | grep -o 'initialSettings":[^,]\{0,20\}'`
**What broke the streak:** three consecutive recreates came up empty, then
rolling the 8.6 MB `conf/homepage/logs/homepage.log` aside and recreating healed
it within 15 seconds. That is one observation, not proof — but it is a coherent
mechanism (oversized log → logger init throws → silent catch) and it is the
cheapest thing to try first next time.

# `[2026-08-24, pass 3]` Rebuilt on Australis Skyfall — dual theme, light shipped
Operator supplied the Skyfall design-system README and said "Go full with
skyfall."
## The bundle was already in this repo's git history
**The Skyfall tokens did not need to be hunted down.** A predecessor vendored
them on 2026-08-19 and a later commit deleted them; git kept everything:
```bash
git show 45c1995:stacks/homepage/theme/colors.css # 208 lines, BOTH themes
git show 45c1995:stacks/homepage/theme/layout.css # calm-depth tokens
git show 45c1995:stacks/homepage/theme/typography.css
git show 45c1995:stacks/homepage/theme/fonts/Supreme-{400,500,700}.woff2
```
`colors.css` carries `:root` (dark) **and** `[data-theme="light"]` (Skyfall
Day) — so the light ramp is canonical, not derived. That killed the entire
objection from the previous answer, which was correct only about the
`australis-design` skill ("Always dark first. No light mode in this system").
**Skyfall is the dual-theme derivative; australis-design is the terminal
theme. They are different systems and only one of them has a light mode.**
## ⚠⚠ REMOVING `theme:` FROM settings.yaml BREAKS THE DASHBOARD
The documented way to get Homepage's own light/dark toggle is to leave `theme:`
unpinned. **Do not.** With the key absent, the page's data loader throws and its
catch branch serves `initialSettings: {}` — no tab bar, no layout, no i18n.
Measured, not inferred: six force-recreates over seven minutes all came up
empty with the key removed; restoring `theme: dark` rendered correctly on the
next recreate in **12 seconds**. `/api/services` stays 200 and fully correct
throughout, which is exactly why this reads as a caching or warm-up problem and
is not one.
This is the first *confirmed* trigger for the long-running "tab bar goes
missing" mystery. It does not explain every occurrence (the symptom has
appeared with `theme:` present), but it means **the first diagnostic step is
now `git log -p -- stacks/homepage/conf/settings.yaml`**, not container
archaeology. Also retires an earlier lead from this same session: rolling the
8.6 MB `homepage.log` aside once coincided with a recovery, but did nothing
during the `theme:`-key episode — coincidence, not cause.
## So the toggle is ours
`conf/custom.js` renders it (was an empty placeholder). Precedence:
1. explicit choice — `localStorage['skyfall-theme']`, written by the toggle;
2. OS preference — `@media (prefers-color-scheme: light)`;
3. dark — Skyfall's default.
`theme/build.py` re-emits each vendored `[data-theme="light"]` block twice: as
`[data-theme="light"], html.light`, and inside the media query scoped to
`html:not([data-theme="dark"]):not([data-theme="light"])`. **That `:not()` pair
is what lets a stored *dark* choice survive a light-mode OS.** Verified across
both OS preferences: load, click, click again, reload — all four correct.
⚠ Homepage keeps its own `class="dark scheme-dark theme-slate"` on `<html>`
regardless, because `theme:` is pinned. That is fine and was checked
explicitly: with the dark class present AND `data-theme="light"`, every themed
surface resolves to Skyfall Day, because our rules carry `!important` on the
surfaces Tailwind's `dark:` variants would otherwise claim. **`data-theme` is
the control surface; the class is not.**
## The anti-fork guard is now mechanical
`build.py` records the SHA-256 of each vendored file and **fails the build** on
a mismatch, rather than warning. A vendored file is either byte-identical to
the bundle or it is a fork wearing the bundle's name. Overrides go in
`skyfall.css.in`, which is written entirely against the semantic layer
(`--surface-*`, `--text-*`, `--border-*`, `--success/--danger/--warning`) — no
raw family tokens, no colour literals.
The one place a literal is unavoidable: Homepage consumes
`--color-logo-start/stop` as `rgb(var(--x))`, which cannot take an `oklch()`.
Those four values are exact sRGB conversions of real tokens (`--sea-80`,
`--blue-base` for dark; `--sea-40`, `--blue-deep` for light), computed rather
than eyeballed, with the conversion recorded in the file.
## Deviations, all deliberate and all written down
- **The aurora ribbon under the tab bar is gone.** Skyfall sanctions exactly two
accent expressions — the active rail and hero-only glows — and a decorative
gradient across the chrome is neither. The colour moved to a 2px accent bar
plus `--accent-soft` fill on the active tab, which *is* the rail.
- **Widget stat values moved from the display face to mono**, per Skyfall's
"numbers and telemetry are always `--font-mono`".
- **Two font substitutions**: Space Grotesk for Bespoke Sans, JetBrains Mono
for Victor Mono. Only Supreme was ever vendored, and Skyfall's own notes call
Victor Mono "user-supplied". Two-line swap when the real faces arrive.
Dark + light, all four tabs: `http://10.100.10.50:8090/b/homepage-skyfall/`

# [2026-08-24] Scriberr transcription deployed on ana-ml2, GPU1
Self-hosted audio/video transcription + diarization. Operator chose GPU
placement over ana-docker (8 cores shared with 50 containers, 37 GB disk)
against ana-ml2's 96 cores, `/tank`'s terabytes and GPU1's headroom.
**Live:** `http://scriberr.ana.internal:8080` (DNS alias added), health `healthy`,
all seven backends up, zero failures: `whisperx pyannote sortformer parakeet
canary voxtral openai`. ~30 GB of weights on `/tank`.
Stack: `stacks/scriberr/`. Full gotcha list in auto-memory
`reference_scriberr_ana_ml2`.
## Three upstream bugs, none of them ours
**1. The Blackwell image does not exist.** Upstream's README documents
`scriberr-cuda-blackwell`; GHCR has **no tags for it**. Published
`scriberr-cuda` covers sm_61–sm_89 only — on these sm_120 cards it fails or
silently drops to CPU. The real sm_120 path is `Dockerfile.cuda.12.9`
(CUDA 12.9.1, cu128 torch), **built from source**. Do not "simplify" the compose
back to the published image.
**2. It must run as uid 10001, not 1000** — and the error lies:
`unable to open database file: out of memory (14)`. Error 14 is
`SQLITE_CANTOPEN`, not an OOM, on a box with 566 GB RAM. That Dockerfile creates
`appuser` at 10001 (Ubuntu 24.04 owns uid 1000 as `ubuntu`) and chowns `/app` to
it, while the entrypoint's PUID remap covers only the data dirs.
**Isolated by elimination**: SQLite writes fine to `/tank` as 1000 → not the
mount; fails on a plain named volume too → not the storage; the **published CPU
image works at PUID=1000** because there `appuser` *is* 1000.
Generalisable: *when a container "permission" bug appears, compare the uid the
image was BUILT for against the uid you are RUNNING as.*
**3. `UV_LINK_MODE=copy` is required.** Scriberr builds each backend's Python env
with `uv` at start; uv's reflink mode fails on overlayfs+ZFS with
`Failed to clone … Resource temporarily unavailable (os error 11)`. **Partial
failure** — WhisperX and PyAnnote came up and the app looked fine while Parakeet
and Sortformer were silently absent. Occurrences 2 → 0 after the fix.
## Related
`speaches` on irv-ml1 **stopped** the same day (stack retained, one command to
restart): Eyra was abandoned pre-implementation because Scriberr covers the need,
leaving it with no consumer. Scriberr runs its **own** WhisperX in-container and
is **not** a speaches consumer. Idle footprint at stop was 274 MiB, not the
~5.9 GB quoted — that figure is the loaded-model working set.

- **docker-as-root pattern** (for ops that have no admin API, e.g.
`SqliteUserStore.set_bifrost_credentials`): on hosts where the SSH
user is in the `docker` group but lacks passwordless sudo, run
`docker run --rm -v <target-dir>:/wt -v /var/run/docker.sock:/var/run/docker.sock docker:cli sh -c "..."` to edit deploy-owned files
without sudo. Documented with security warning in
`servers/corviduo-dev/README.md`. docker-group membership is
effectively root via bind-mount; treat as a sudo-equivalent grant.
**Foot-gun: when running `docker compose` inside this sandbox,
any relative path in compose.yaml (e.g. `${WORLDTREE_CONFIG_DIR:-./config}`)
resolves against the sandbox CWD, but Docker daemon interprets the
resulting path against the HOST filesystem. Always pass `-e VAR=/abs/path`
to the docker run invocation for any relative-default config dir.**
- **gitea internal route for fleet hosts.** gitea is a container on
**ana-docker** — git-SSH `10.250.50.70:222`, HTTP `:3000`. Fleet/colo
hosts must use this internal route, NOT public `gitea.phasefinal.com`
(`38.120.12.44`) — the public path fail2bans the host egress IP. Full
gotcha in `docs/orientation.md` → Git/gitea.
- **docker-as-root pattern** (for ops with no admin API, or to edit
deploy-owned/root-owned files without sudo): `docker run --rm -v
<target-dir>:/wt docker:cli sh -c "..."`. docker-group membership is
effectively root via bind-mount. **Foot-gun: relative paths in compose.yaml
resolve against the sandbox CWD but the daemon interprets them against the
HOST fs — always pass `-e VAR=/abs/path` for any relative-default config dir.**
- **`scripts/elway` sudo handling** — elway prompts for the sudo password
ONCE via `getpass` before the first `sudo: true` step. That prompt is
interactive → elway can't run unattended from a non-TTY tool if any step
needs sudo. For sudo-free playbooks (no `sudo: true` steps) it runs fully
non-interactive over key SSH. To create root-owned dirs WITHOUT host sudo,
use the docker-daemon-root trick: `docker run --rm -v /worktank:/mnt alpine
sh -c 'mkdir -p /mnt/<x> && chown -R 1000:1000 /mnt/<x>'`.
ONCE via `getpass` before the first `sudo: true` step → can't run
unattended from a non-TTY tool if any step needs sudo. Sudo-free
playbooks run fully non-interactive over key SSH.
- **Per-host SSH identity matters for sudo.** infra-ops has NOPASSWD sudo
on most PFI Linux boxes (corviduo-dev included since 2026-06-15). On
ana-docker: **default `ssh ana-docker` = `lkraven`** (docker-group, NO
passwordless sudo); **`ssh infra-ops@ana-docker` HAS NOPASSWD root**. **→
For any sudo op on ana-docker, use `ssh infra-ops@ana-docker`.** `ssh
infra-ops@10.100.10.50` (nh3-dev) ALSO NOPASSWD sudo; on **nh3-extdev** infra-ops
is sudo-LESS by design (`ssh lkraven@10.100.50.42` is the NOPASSWD path). **irv-ml1:
`ssh irv-ml1` = lkraven, docker-group (plain docker) but sudo needs a PASSWORD
(no NOPASSWD)** — stage model pulls to `/home`, not root-owned `/worktank`.
## Current state / in-flight
_As of 2026-06-05:_
_As of 2026-08-25 ~04:20Z — the ERP/RP tune is TRAINING on ana-ml2 GPU0, ~17h, unattended. The homepage and char-rp arcs closed earlier. **The live thread is the run itself plus a parallel question: whether a fused MoE kernel lands fast enough to justify restarting it.**_
- **Granite-FP8 + observability session — all LIVE & committed (`34a43a0`, `9171e6a`).**
- **Granite 4.1 8B FP8 is the production summarizer** (`vllm-granite` :8004, ana-ml2 GPU 1,
50K ctx, CUDA graphs) — replaced phi4-mini, validated by brokkr (valid_format 1.0, FP8 stays).
- **LiteLLM gateway** (:4000) routes `granite-4.1-8b`→vLLM (explicit entry shadows the `*`
wildcard) + **Langfuse v3 wired** (ana-docker:3001, "LLM Throughput (tok/s)" dashboard built).
- **GPU-1 retuned** (trio over-provisioned KV trimmed) → granite runs with CUDA graphs + ~10 GB
free as a future Granite-text-LoRA hedge. Streaming through the gateway confirmed (TTFT 0.24s).
- **ana-docker pruned** 77 GB (unused images + build cache; disk 83%→49%) to fit ClickHouse.
- **Worldtree summarizer repoint — NO instance change now; DEFERRED to Worldtree #254** (see Recent
decisions). worldtree-dev will ping with the providers.yaml + consumer config when #254 un-holds;
infra-ops applies to the personal/demo/pinned bind mounts (vh@10.250.50.152, `/opt/worldtree*/config`).
- **Commits unpushed** (`34a43a0`, `9171e6a`, nevermore `d3e19b8` in its repo) — operator's call to push.
- **Operator flagged "new work to do"** for the next session — this snapshot is the handoff.
- **Disclosed-keys hygiene queue** (rotate at convenience): HF token `hf_HBl…` (lkraven's), `/tmp/
wt-personal-skaldsong-prod.key`, Worldtree `Z_AI_API_KEY`, Gitea runner reg token, `MINIFLUX_PASSWORD`
(leaked twice). (sk-corvid + the langfuse/vastblueai-gateway keys are dev-enclosed — leakage deprioritized.)
- **Still open from prior:** clean legacy `news-digest` on ana-docker; watch nh3-nas `/volume1`; **pin
llama-swap to GPU 0** for clean GPU-1 separation; the `docker push 60s ceiling` mystery uninstrumented.

GPU0 runs **84,222 MiB of 97,887** (above my measured 79.71 GiB worst case — adjacent `#w0`/`#w1` windows share micro-batches systematically, exactly as brokkr predicted). **Encode is CACHED** (`run-01/encode-cache/`, keyed on encode_version+max_seq_len+template sha) so a restart costs ~2.5 min, not the 4.3h it would single-threaded. ⚠ **encode_version must be BUMPED on ANY encoder change** — that has mattered five times. **RESUME: use `/tank/erp-tune/resume-run-01.sh`, NEVER the original launch command** — that one starts `rm -rf /tank/erp-tune/run-01`, which destroys the 609 MB encode cache AND every checkpoint. First checkpoint at step 100; `save_steps=100` at ~46.5 s/it = **~73 min of crash exposure** per interval. → `docs/pfi/gemma4-erp-tune-sizing.md`

Other un-excluded candidates: the chunked CE (vocab 262,144 + softcap, 1024-tok chunks re-materialised under `checkpoint`), the `attention_k_eq_v` K=V path, grad-ckpt × MoE dispatch interaction, PEFT's wrapper on 205 modules. ⚠ **My earlier "5% MFU" was ALSO wrong** (divided by UNPADDED tokens, compared against a GUESSED peak) — operator caught it. Padding is a real but secondary **29.9%** tax (82,337,318 padded vs 57,733,156 real).

Background: Every `clean-v1/CLEANROOT.json` carries `training_eligible: false` with `training_blocked_by: [contamination-scan-not-implemented, stage-2-csam-detector-inert]`, and the recipe itself says *"nothing here is Charter §3 training-eligible"*. ⚠ **`scoped_grant: operator-2026-08-22` is NOT training clearance** — it governs INV-4 one-way tier inheritance (the adapter is permanently `internal-erp-rnd`, never distributable). I initially misread the grant as authorization and told brokkr I was proceeding; **brokkr-smithy-dev — who WROTE those fields — corrected it**: *"I wrote them so that exactly this would happen… do not take my word as clearance; I do not have the authority to give it."* **The detector is measured-inert, not suspected:** `auditcore` v3.7.2 returned its hard-drop rc-2 **zero times across 42,662 raw RP records**, its printed verdict ignores its own printed threshold, and it passed a blind-audit-identified record of sexual content involving a participant the text marks as a child (`pippa-5083`, composite 4.34 vs threshold 6.5). → `research/R47-premium-corpus-gate/FINDING-auditcore-inert.md`, Contract Amendment 11. **I verified the one decisive thing:** `pippa-5083` IS in `kept-manifest.jsonl` (4,551 rows) but **ABSENT from `recipe-dedup-kept.jsonl` (20,473 rows)** — the survivor list the harness gates on — so brokkr's substitute *stage-A lexical* screen caught it. That is one known instance caught by a stopgap; it says nothing about what the screen misses. **Both brokkr and I recommend STOPPING; only an explicit operator override opens it.** Neither blocker is hours of work (the 13-gram scanner is spec-only, DRAFT since 2026-06-01; the detector needs replacing). ⚠ **Do NOT stage or copy corpus content while gated.**
- **🟢 SIZING + SEAT CALL — DONE AND EXECUTED, full detail in the doc.** QLoRA structurally unavailable (fused 3-D experts vs bitsandbytes' nn.Linear walk); plain BF16 LoRA; chunked CE mandatory (naive CE OOMs at seq16384, 81.93 GiB at seq8192); `v_proj` exists on only 25 of 30 layers (`attention_k_eq_v`, K=V sharing — real, not a miss). `gen` moved to GPU1, `sec` down, GPU0 dedicated. → `docs/pfi/gemma4-erp-tune-sizing.md`, `playbooks/ana-ml2-training-window-{open,close}.yaml`
- **⚠ TELL EITRI BEFORE HE HARD-CODES: the trainee base changed.** Contract still names the stock BF16. It is now `/tank/aimodels/gemma4-26b-a4b-it-heretic-bf16` (llmfan46). **Base path AND chat-template path must be config keys, not constants** — and the template must point at upstream's (`gemma4-26b-a4b-it-bf16/chat_template.jinja`), never the base's own, or training renders a different prompt than production serves.
- **🟢 char-rp seat = Gemma-4 26B-A4B MoE NVFP4** on `:8016`, both aliases on ONE backend. **Currently DOWN by operator instruction** to hold GPU0 headroom for the tune. `gen` is UP and verified. MeroMero-v2 retained stopped in `created` state for rollback (stop-then-start; both bind :8016). → `persistent-memory.d/2026-08-24-charrp-gemma4-moe-swap-and-trainee.md`
- **🟢 THREE trainee-relevant model dirs on `/tank/aimodels/`, NOT interchangeable:** `gemma4-26b-a4b-it-bf16` (stock, 49 GB — its chat_template is the canonical upstream one), `gemma4-26b-a4b-it-heretic-bf16` (llmfan46 abliterated, the trainee), `gemma4-26b-a4b-it-abliterated-bf16` (TrevorJS, KL 0.09, alternate). Plus `-nvfp4` (served) and `-nvfp4a16` (activation control). ⚠ **BF16 cannot coexist with `gen`** — 48.07 GiB of weights on a 94.97 GiB card. Every BF16 window means gen stops.
- **🟢 `stacks/gemma4-trainee-bench/`** is the ephemeral BF16 bench stack — no `--quantization` flag (the production compose hardcodes `compressed-tensors` and crash-loops on BF16), `restart: "no"`, no homepage labels. Base swap is ~5 minutes because it exists.
- **🎨 Homepage runs AUSTRALIS SKYFALL with a working light/dark toggle**, recategorised on "do I open this?" (TOOLS expanded / ENDPOINTS collapsed). ⚠ **`theme:` MUST stay pinned in settings.yaml** — removing it makes the page loader throw and serve `initialSettings: {}`, the first *confirmed* trigger for the "tab bar goes missing" mystery. → `persistent-memory.d/2026-08-24-homepage-uniform-grid.md`
- **🔒 ana-gw's public admin surface is ZERO open TCP ports**; box scheduled for replacement by **OPNsense on a Dell R420** (brings WireGuard onto the edge — the downstream-WireGuard-VM design is moot, do not scope it). **No out-of-band path remains** — if both tunnels drop it is console-only. → `persistent-memory.d/2026-08-24-ana-gw-admin-closed-acme-disabled.md`
- **🟢 Both Anaheim IPsec tunnels run AES-128.** NH3 245→**270 Mbit/s**, ESH 268→**304**. Ceiling is **the UDM's software AES-CBC, not the FortiGate**. → `persistent-memory.d/2026-08-23-anaheim-ipsec-tunnel-ceiling.md`
- **🟢 Scriberr LIVE** — ana-ml2 **GPU1** :8080, built locally, uid **10001**, needs `UV_LINK_MODE=copy`. → `persistent-memory.d/2026-08-24-scriberr-ana-ml2.md`
- **🟢 ESH DNS fixed at the IPv6 layer**; RDNSS **redirected** to AdGuard. ⚠ Proxmox bridges need `accept_ra=2`. Naming scheme lives in `docs/pfi/ipv6-naming-scheme.md` — **a convention, not memory state; never let a memory line be the only copy again.** → `persistent-memory.d/2026-08-24-esh-dns-rdnss-and-scheme-live.md`
- **🟢 SEAT MAP.** ⚠ **ana-ml2 runs a vLLM VERSION SPREAD, not one version** — do not say "ana-ml2 runs X". Measured 2026-08-24: `gen` **0.27.2rc1.dev150** (`nightly-311b3513`), `mog-sec` **0.26.1rc1.dev1102** (`nightly-e9d1398d`), `rerank-a3`/`coder`/`reward`/`embed` **0.24.0**, char-rp + trainee-bench pinned **v0.26.0**. `v0.27.1` (tagged) and three nightlies sit on disk unused. **`gen`** = Qwen3.8-27B-Uncensored NVFP4-mixed, GPU0 :8015, 7 aliases, UP. **`char-rp`** = Gemma-4 MoE NVFP4, GPU0 :8016, DOWN deliberately. **`sec`/`sec-reasoning`** = M.O.G.-SEC, GPU1 :8019, sharing GPU1 with Scriberr.
- **⚠️ THE `sec` DEGENERATION QUESTION IS STILL OPEN AND CONFOUNDED.** Isolating experiment is **MTP k=3 on `e9d1398d`** — still not run. Operator ruling: degeneration lives in the **un-fixed vLLM**, not the weights; MTP-head hypothesis **retracted**. Both sightings n=1.
- **🟢 ana-ml2 mounts `/mnt/smithy`** ro + soft, **NOT in fstab** — manual remount after reboot. `nconnect=8` approved but deliberately not applied. → `persistent-memory.d/2026-08-23-smithy-mount-ana-ml2.md`
- **🟢 ESH IS DUAL-STACK**; v4 static is an unprovisioned Cityside ticket. **NH3 stays v6-off by explicit ruling.**
- **⏳ OPEN ELSEWHERE:** MTP-k3 isolating experiment; upstream vLLM issue to file; Cold-Fusion NVFP4 quants (44 GB) delete/keep; OWUI image-tag drift; `/tank` DEGRADED **70+ days**; Worldtree **#411** debug-room litter; Lobe retirement is the operator's call; brokkr's `gen` vs trained-reward-model bake-off. **Commits are local and unpushed** — push is the operator's call.
- **⚠️ STANDING: NO FLEET NOTIFICATIONS unless the operator asks** (2026-08-24). Direct task correspondence with a counterparty is fine; unsolicited broadcasts are not.
## Recent decisions
- `[2026-06-05]` **Granite 4.1 8B FP8 replaced phi4-mini as the production summarizer** (supersedes
the 2026-06-04 phi4 decision below). Beat phi4 on precision in brokkr's R15 P03. **Staying FP8, not
Q4/AWQ** — primary workload (agent memory + summarization) is high-concurrency, where FP8-on-Ada
scales ~linearly (profiled 2010 tok/s @ C=32; single-stream 67.5 is batch-1 GEMV physics, not a
config bug — placement/kernel/contention all ruled out). vLLM `vllm-granite` :8004 GPU 1, official
IBM compressed-tensors FP8, CUDA graphs. **GPU-1 retune** (trio utils 0.2/0.2/0.3→0.07/0.07/0.18,
granite 0.36) freed ~10 GB → CUDA graphs + a Granite-text-LoRA hedge. nevermore repointed. (`34a43a0`,
auto-memory `reference_ana_ml2_vllm_granite`)
- `[2026-08-25]` **Fused MoE kernel path — DEFERRED, tracked at park `fused-moe-kernel-path-for-gemma-4-moe-training` (id 47).** Operator: "note the fused MoE kernel for round two… if we nail it soon, the math has us wanting to restart the run anyway." Training MFU is **8.6%** (27.1 of a benchmarked 313.8 TFLOPS) because `transformers` runs the Gemma-4 experts in a Python loop — 128 experts × 30 layers, ~11,500 iterations per step under gradient checkpointing. ⚠ **The same fused 3-D expert layout that made bitsandbytes skip 88.5% of the model is exactly what a grouped GEMM wants** — the format is good for storage and for fused kernels, and hostile only to naive iteration. Two fixes: `group_by_length` (−29.9% compute, free, but breaks the seeded order manifest and re-opens a batch-composition call brokkr already made) and a grouped-GEMM/compiled MoE forward (the remaining ~10×). **Not applied to the live run** — restarting mid-flight to change batch ordering was judged a bad trade at step ~50 of 1,312.
- `[2026-08-25]` **The ERP/RP tune LAUNCHED after 12 harness defects and an operator override of the corpus gate.** Four of the twelve would have crashed the run; two were INERT GATES that passed because they could not fail. Run is `/tank/erp-tune/run-01`, harness eitri-smithy `997c4a4`. Full arc — override, defects, sizing, the measured MFU — in the in-flight section and `docs/pfi/gemma4-erp-tune-sizing.md`.
- `[2026-08-24]` **char-rp seat swapped to the Gemma-4 26B-A4B MoE; abliterated trainee base staged and measured.** OOM root-caused to `--gpu-memory-utilization` not covering CUDA context (and to gen's footprint GROWING WITH UPTIME); a benchmark finding retracted because it scored below chance; abliteration isolated at −0.6 core points but it MOVES capability rather than removing it. → `persistent-memory.d/2026-08-24-charrp-gemma4-moe-swap-and-trainee.md`
- `[2026-08-24]` **Serving the tuned ERP model: LoRA-on-NVFP4 PREFERRED, merged weights the expected fallback — and the recorded objection may be STALE.** Operator: "if you CAN load it as a lora, all the better, the issue is that we will want to run nvfp4 weights, which we had some serious trouble with loading loras on top of nvfp4." ⚠ **The archived root-cause says it was NOT NVFP4-specific**: `[2026-07-07]` vLLM 0.24.0 qwen3_5 LoRA application was a silent no-op (#47639, regression from #37912) — adapter loads HTTP 200, zero deltas at inference, proven **quant-agnostic (NVFP4 AND FP8 both inert)** and adapter-format-agnostic by a 3-peer dwarf panel. Fix PR #47640 was OPEN then. **ana-ml2 is FAR past 0.24.0 and the box runs a SPREAD, not one version** (measured 2026-08-24): `gen` on `nightly-311b3513` = **0.27.2rc1.dev150**, `mog-sec` on `nightly-e9d1398d` = 0.26.1rc1.dev1102, the small seats still on 0.24.0, and char-rp/trainee-bench pinned to v0.26.0. ⚠ **`vllm/vllm-openai:v0.27.1` is already ON DISK, unused** — a TAGGED release, which is the right retest target: no nightly variance, no pull, ~4 months past the diagnosis. So: RETEST hot-swap LoRA on **v0.27.1** before designing around merge — it is cheap, and if it works the post-tune gate can be two aliases on one engine. If it still no-ops, merged weights it is, which means the harness must EMIT merged weights and Eitri needs that in the contract while he is early. Tracked at this snapshot commit; settle it in the QLoRA sizing conversation.
- `[2026-08-24]` **Homepage rebuilt on Australis Skyfall; light mode shipped.** Two findings worth more than the theme: **(a)** the Skyfall bundle including its canonical light ramp was sitting in this repo's git history at `45c1995` — check `git show` before concluding a vendored design asset is lost; **(b)** removing `theme:` from `settings.yaml` deterministically breaks the dashboard render (six recreates empty, restoring the key fixed it in 12s), which is the first confirmed cause of the "tab bar goes missing" symptom. Retires the `homepage.log` size lead from earlier the same day — it did nothing on this episode. → `persistent-memory.d/2026-08-24-homepage-uniform-grid.md`
- `[2026-08-24]` **Homepage reorganised on the axis "do I open this?" — UI groups expanded on top, API/agent groups collapsed at the bottom** (operator-delegated: "re-categorize however you want"). Load-bearing constraint: `homepage.group` is read at container CREATION, so the 16 GPU-backed model seats keep their unlovely names rather than eat a recreate — `initiallyCollapsed` + order is free. Second rule discovered here: **group members should all have widgets or none should**, because a stat strip adds ~50px and opens a void beside plain cards. → `persistent-memory.d/2026-08-24-homepage-uniform-grid.md`
- `[2026-08-24]` **Homepage columns unified at 4 for every group; the 2026-08-18 "columns = member count" rule is retired.** It was avoiding dead cells in a short last row and bought a worse defect — card width changing at every group boundary. Also carries two CSS traps: `overflow: hidden` clips at the PADDING box (so a `padding-right` gutter is spill room, not a guard), and a `:root` override of a Homepage theme variable is silently outranked by `.theme-slate` on the same `<html>` element. → `persistent-memory.d/2026-08-24-homepage-uniform-grid.md`
- `[2026-08-24]` **AES-128 adopted on both Anaheim tunnels; the per-flow ceiling root-caused to the UDM's software AES-CBC, exonerating the FortiGate.** Proven by an A/B/A cipher swap at identical CPU — hardware offload is not cipher-cost-sensitive. → `persistent-memory.d/2026-08-23-anaheim-ipsec-tunnel-ceiling.md`
- `[2026-08-24]` **ana-gw's public admin surface closed to zero open ports, ACME listener included.** Two of my diagnoses were wrong first (an "ISP proxy" that was the FortiGate, and an "all-port VIP" alarm that was a parser gap) — both from reading config instead of measuring from outside. → `persistent-memory.d/2026-08-24-ana-gw-admin-closed-acme-disabled.md`
- `[2026-08-24]` **Scriberr deployed on ana-ml2 GPU1, image built from source.** Three upstream bugs: the Blackwell image was never published, it must run as uid 10001, and `UV_LINK_MODE=copy` is required or two backends fail silently. → `persistent-memory.d/2026-08-24-scriberr-ana-ml2.md`
- `[2026-08-24]` **ESH DNS fixed at the IPv6 layer and the naming scheme went live on three hosts.** UniFi's RDNSS cannot be disabled but CAN be redirected — the field is only honoured when an explicit server is given. → `persistent-memory.d/2026-08-24-esh-dns-rdnss-and-scheme-live.md`
- `[2026-08-24]` **`speaches` on irv-ml1 stopped, stack retained** — Eyra was abandoned pre-implementation (Scriberr covers the need), leaving it no consumer. Disposition confirmed to eyra-dev; one command to restart. Tracked at althing thread `01M0RRJX8GPZEBDHF1E3W18RZF`.
- `[2026-08-24]` **esh-vm-db brought onto the fleet infra-ops identity and given its first vaulted credential.** It previously had none: root and infra-ops refused key auth and `lkraven`'s sudo wanted a password nobody held, leaving `qm guest exec` from the hypervisor as the only privileged path. Break-glass root password at `secret get esh-vm-db/root-breakglass-password` (console-only; plaintext never crossed the wire — only its SHA-512 hash did).
- `[2026-08-24]` **`nconnect=8` on `/mnt/smithy` — approved but DEFERRED at operator instruction.** brokkr-smithy-dev pre-approved it for "once the FortiGate work settles" and does not need re-asking; the operator declined it in this session's scope. Tracked at althing thread `01M0R46SFYF83099N16WD67KGD`.
- `[2026-08-23]` **Anaheim's IPsec tunnel ceiling — investigated, then CLOSED 2026-08-24.** The 25%-of-2-Gbps framing was wrong (NH3's uplink is 1 Gbps); AES-GCM proved impossible; AES-128 landed instead. → `persistent-memory.d/2026-08-23-anaheim-ipsec-tunnel-ceiling.md`
- `[2026-08-23]` **selene retired after losing a head-to-head on its own job; `chat-judge` moved to gen, the model name 404s by design.** Also surfaced that **7 aliases share one seat** — cross-checking between them is an echo, which caught a real defect in brokkr's 46k-exposure R47 gate. → `persistent-memory.d/2026-08-23-selene-retired-alias-collision.md`
- `[2026-08-23]` **hrafn adopted; its CI reported green for its whole life while deploying nothing.** A staging dir inside the rsync target destroyed its own source mid-copy; the deeper fault was verify steps that asserted uptime, never content. → `persistent-memory.d/2026-08-23-hrafn-adopted-ci-frozen-source.md`
- `[2026-08-23]` **Worldtree b187 shipped; all three instances de-armed from a 69-day-stale `:latest`; Matrix homeserver re-plumbed to personal.** Includes the `:8009`-is-demo port trap that an IP-only fix would have walked into. → `persistent-memory.d/2026-08-23-worldtree-b187-pins-matrix.md`
- `[2026-08-23]` **Every secret-bearing `.env` on ana-docker tightened to 0600** — eight stacks including vaultwarden and traefik, verified exposed by reading one as `nobody`. → `persistent-memory.d/2026-08-23-ana-docker-env-perms-sweep.md`
- `[2026-08-23]` **`pfi` gitea org created; claude-bot is an Owner and creates repos self-serve.** Closes the repo-creation half of the credential-migration directive — `vh` is a USER namespace so no service account could ever create there. Repo creation needs `write:user` + `write:repository` + `write:organization`; `POST /users/{u}/tokens` is basic-auth only, so minting needs the account password. Default new repos to `pfi/`. (`vh/eitri-smithy` was its first tenant, then moved.)
- `[2026-08-23]` **Booth: kept boards are deletable and link rows are prunable.** `release` on a kept card drops the sentinel so the existing × applies; `booth links` / `booth unlink <id|index>` prune one row. Rows are addressed by **content id, never position** — the board is append-only and multi-writer. **Releasing a board RESETS its TTL clock** (unlink bumps the dir mtime), so unkeep-and-wait is a 24h delay, not a delete. (`4be880f`, `0ad332b`)
- `[2026-06-05]` **Langfuse v3 stood up on ana-docker (:3001) as the gateway trace UI**; LiteLLM
`success_callback:[langfuse]` live (project `gateway`). Pretty prompt/completion/reasoning traces +
an `outputTokensPerSecond` tok/s dashboard. NOT a prerequisite — spend_logs already capture
tokens+latency. (`9171e6a`, auto-memory `reference_litellm_gateway`)
- `[2026-08-22]` **DFlash2 spec-decode measured on our own stack; `sec` promoted to it.** +18–21% accepted length and +15–18% throughput over MTP k=3, drafter proved model-agnostic across two finetunes to 0.06%, and the k=7 MTP *control* showed deeper MTP is a throughput trap. → `persistent-memory.d/2026-08-22-dflash2-spec-decode.md`
- `[2026-08-22]` **Quant pipeline shipped a crippled tokenizer for months — fixed at source.** `quant_mixed_nvfp4.py` baked its calibration truncation (`max_length 2048`) into every mixed-NVFP4 build; latent on old transformers, fatal on new. Both live quants corrected, pipeline now saves a source-pristine tokenizer and asserts it. Playbook §3.14. (`0755ba7`)
- `[2026-08-22]` **`sec` retuned to util 0.52 / 420K after a runtime OOM at 0.55/480K** — `gpu-memory-utilization` is not a hard reservation; activation grows past the dummy-data profile and six vLLM containers share GPU1. Also measured: the KV pool varies ~6.6% between boots, so max-model-len must be sized against the *lower* observation. (`6e82899`)
- `[2026-08-22]` **Max-Q 1.8× spread does NOT apply to LLM decode — measured, not argued.** ana-ml2 draws 256–266 W of 300 W under sustained 100% decode with `SW Power Cap: Not Active` and clocks pinned. Corrected to brokkr-smithy-dev after I had lent the claim credibility; 122B figure (~90–93 tok/s at 262K) stands as a straight number.
- `[2026-08-21]` **ESH internal IPv6 live on two LANs; the Cityside v4 static is a CARRIER problem, proven.** A full gateway reboot forced a fresh DHCP DISCOVER and returned the identical CGNAT address. YaRN was already configured — "1M needs YaRN, absent" was false. → `persistent-memory.d/2026-08-22-dflash2-spec-decode.md` sibling entry in `ad21302`
- `[2026-08-21]` **speaches ASR live on irv-ml1 for Eyra — and `no_speech_prob` alone is a weak hallucination gate.** Silence and room tone both hallucinated "Thank you." under 0.11; `avg_logprob` separates ~6× better. Consumers should gate on a composite. (`aa5863c`, `c7e2187`)
- `[2026-06-05]` **Ollama BANNED fleet-wide** (operator directive) — never stand one up; tear down any
found; serve via llama-swap or vLLM. Torn down irv-ml1 :11434 (freed 19 GB). (auto-memory
`feedback_avoid_ollama`)
- `[2026-08-20]` **Cold-Fusion abliteration — Robinson recipe captured; the fight was the environment, not the recipe.** Stock Cold-Fusion measured ~33% creative refusal → worth abliterating ourselves (supersedes waiting for DavidAU's heretic build). Recipe maps 1:1 (131 tensors); capture succeeded only in **fp32** — transformers' Qwen3.5 DeltaNet linear-attn NaNs nondeterministically in bf16 without the unbuildable `causal-conv1d` kernel (precision cancellation, not overflow). Direction finite at layer 22 but agreement 0.59 (vs Robinson's 0.99) → **calibration-set expansion is next.** → `persistent-memory.d/2026-08-20-coldfusion-abliteration-capture.md`
- `[2026-06-05]` **ComfyUI / FLUX.2 work split to `~/development/comfy-dev`** (dedicated repo + agent).
FLUX.2-klein (fp8 + q8 GGUF, stock + uncensored encoders) installed on the irv-ml1 Docker ComfyUI;
eshpfi keeps the `comfyui` stack compose, comfy-dev owns the model/workflow knowledge. (auto-memory
`reference_irv_ml1_ampere_quant`)
- `[2026-08-19]` **A *software* watchdog is not watchdog protection — esh-pve froze for 4.5h holding one.** softdog cannot fire when the kernel it runs in is wedged, and Proxmox's `watchdog-mux` never arms without HA resources, so the box *looked* protected and wasn't. Moved to the PCH `iTCO_wdt` under systemd. Also: a single cross-VLAN DNS entry with no secondary turns any VM outage into a whole-site outage. → `persistent-memory.d/2026-08-19-esh-pve-freeze-dns-spof.md`
- `[2026-06-05]` **Worldtree summarizer config refresh DEFERRED to Worldtree #254** (granite-4.1-8b is
the structured-output profile, ON HOLD, no live consumer; the conversation summarizer defaults to
claude-haiku — the "phi4 erroring" premise was wrong). No instance changes now; worldtree-dev hands
the exact providers.yaml + consumer config when #254 un-holds, infra-ops applies to the bind mounts.
**CORRECTION to the 2026-06-04 "deploys ALL CICD" line:** the bind-mount CONFIGS (providers.yaml,
vh-owned on corviduo `/opt/worldtree*/config`) ARE infra-ops's to apply directly — only the
app/image DEPLOY is CICD; the `.env` is deploy-owned. (auto-memory `reference_worldtree_deploys_cicd`)
- `[2026-08-19]` **Fleet `.internal` DNS built and live — git-sourced, agent-managed, three resolvers.** Zone-scoped authority (ESH's hand-made `esteban.net` rewrites survive); the colo had no resolver at all; v6 column empty on purpose because SLAAC addresses rotate. → `persistent-memory.d/2026-08-19-fleet-internal-dns.md`
- `[2026-06-04]` **phi4-mini FP8 on ana-ml2 vLLM is the nevermore summarizer/dreaming agent;
granite-4-small retired** from llama-swap (config-only; GGUFs on disk). 50K ctx (dropped from
Phi-4's 128K max to fit GPU 1's ~10 GB free) + FP8 KV. (`40a374b`)
- `[2026-08-19]` **waterland studio containerised on irv-ml1 — three landmines, all measured.** cupy needs CUDA *headers* the host had by accident; `uv run` re-syncs and prunes cupy at RUNTIME; the A6000 is container-index 0, not the host's 1. → `persistent-memory.d/2026-08-19-waterland-studio-containerised.md`
- `[2026-06-04]` **phi4 ships the CANONICAL/official Phi-4 chat template, NOT Ollama's.**
Ollama's bundled template omits the system `<|end|>` — that flattered brokkr's R15 eval but is
the DIVERGENT scaffold (Dvalin: the system `<|end|>` is Microsoft's intended format). Applied an
Ollama-matching override then reverted — ship correct, not the benchmark quirk. (`90e08f0`→`27eb537`;
"headgun" lesson in Tried.)
- `[2026-08-19]` **Homepage cleaned up, then themed with Australis Skyfall + an Arbo-generated background.** Includes the hour lost to a self-healing tab-bar red herring, and the CSS-iteration loop that prevents it recurring. → `persistent-memory.d/2026-08-19-homepage-skyfall-theme.md`
- `[2026-06-04]` **infra-ops NOPASSWD-sudo identity commissioned, scoped to PFI boxes** (+esh-docker-vm
by operator override) — so infra-ops completes DevOps end-to-end vs handing the operator sudo steps.
Dedicated key, sudo log_output, key-gated. (`8c32a05`)
- `[2026-08-19]` **Four unmanaged stacks found on live hosts — two quietly broken.** A dashboard card is a cheap census of what is actually running; check whether the stack is even in `stacks/` before debugging the symptom. → `persistent-memory.d/2026-08-19-unmanaged-stacks-searxng-seafile.md`
- `[2026-06-04]` **Worldtree demo/pinned/personal deploys are ALL CI/CD, not infra-ops** — a "deploy
vX.Y.Z" request to infra-ops is MISROUTED → point them back to their pipeline. The granite→phi4
repoint: worldtree-dev self-served via their CI/CD (v0.30.10). (`d8d776c`)
- `[2026-08-19]` **`claude-bot` granted read on `vh/waterland`** (operator-empowered, verified `admin:false push:false pull:true`) so irv-ml1 can self-update without the operator's site-admin token living on a GPU box. Precedent for the standing migrate-off-operator-creds directive: grant the service account, wire a repo-scoped 0600 credential helper, keep the remote URL clean. Commit `8189076`.
- `[2026-06-04]` **ollama upgraded 0.9.0→0.30.4 on irv-ml1** (Ministral-3 is a Dec-2025 model the
old engine refused); A6000 pinned by **UUID** not index (native fastest-first ≠ nvidia-smi PCI).
- `[2026-08-19]` **AI-tab Dormant regrouping BELAYED by the operator** — six seats (char-rp Magidonia, char-rp-reasoning Heretic2, Granite summarizer, Qwen-Image-Bench, Skaldsong, Chatterbox Fast) show amber EXITED inside live groups rather than `AI - Dormant`. Fix is a label change + recreate per stack; needs the operator's read on which are retired vs temporarily down. `untracked by operator choice` (his words: "belay the ai dormant regrouping for now").
- `[2026-06-04]` **`brokkr` user (no-sudo) on irv-ml1; R14/R15/R16 substrate moved to /home/brokkr.**
Persistent box services there need SYSTEM systemd units (see Tried).
- `[2026-08-18]` **esh-pve-nas migration STAGED — and staging is where three landmines surfaced, none of which the plan predicted.** (1) The runbook's `/boot` LV had **nowhere to live**: VG `pve` had 4 MB free and mounted ext4 cannot shrink, so the space came from the 768 MB swap LV (operator's call: shrink to 256 MB, not drop). (2) The runbook's `zpool set cachefile=… nvme` would have **broken the NAS** — populating a cache flips the host to import-by-cache, and a one-pool cache leaves `ssd`+`tank` unimported under CT 103's twelve bind mounts. (3) **`update-grub` silently emitted a pool-less `root=ZFS=/ROOT/pve-1`**, because GRUB's ZFS reader cannot open a pool with `encryption`/`large_dnode`/`zstd_compress` and the probe failure is swallowed. All three were caught by *verify steps that asserted effective state*, not by reading the plan. → `persistent-memory.d/2026-08-17-esh-pve-nas-dom.md`
- `[2026-06-03]` **yt-voice-clipper bot-gate fix = route yt-dlp through NH3 residential
egress, NOT cookies/PO-token.** YouTube hard-flags the Irvine colo IP (LOGIN_REQUIRED on a
public video even with no cookies). Cookies + the bgutil PO-token + deno JS-runtime all
loaded fine — the gate is pure IP reputation. Operator chose proxy-via-nh3-dev → durable
dante proxy → proven. The egress proxy is a reusable fleet lever for any datacenter-IP-gated
service.
- `[2026-08-17]` **esh-pve-nas PVE root is on a USB DOM — mitigated, and the migration replanned to split boot from root.** Operator's design beats my reinstall plan; wear was never the issue, blocked patching is. → `persistent-memory.d/2026-08-17-esh-pve-nas-dom.md`
- `[2026-06-03]` **yt-voice-clipper push-to-deploy via gitea webhook** (operator-directed,
after 6 manual rebuilds in ~40 min). Webhook (not poll) — gitea CAN reach the WG IP per the
operator. The proxy env + Homepage labels live in the **host-specific override** (untracked
→ survive the auto-deploy's `git reset --hard`), NOT yt-voice-clipper-dev's image. Runbook
`d4f180d`.
- `[2026-08-17]` **irv-ml1 cleared of 782 GB, and Homepage brought under version control.** One dead-looking Gradio app pinned three delete targets at once; `/opt/ComfyUI` is NOT the ComfyUI that serves. → `persistent-memory.d/2026-08-17-irv-ml1-cleanup-homepage.md`
- `[2026-06-03]` **R14 scope = (a) provision-only.** infra-ops provides box + CUDA env +
engines + weights + NFS; brokkr/dev wires `arms.py` + runs — keeps infra-ops OFF the
VIVAE-processing path (VIVAE = Variably Intense Vocalizations of Affect/Emotion, CHARTER §4
highest-liability; operator authorized R&D-eval-only, quarantined). Box = irv-ml1 (A6000
free; ana-ml2 GPU-saturated). Per-engine venvs (divergent torch stacks); A6000 = `cuda:0`
NATIVE (≠ docker `=1`).
- `[2026-08-17]` **Gen seat swapped to `absolute-heresy` — and the three bugs the swap exposed are worth more than the swap.** Candidate `MuXodious/Qwen3.8-27B-absolute-heresy` (Heretic v1.4.0 + SOMPOA, T377) beat the incumbent on refusals AND KL simultaneously, which is the unusual part — those normally trade off. Validated on the probe port per operator ruling, promoted, all 7 aliases green. **Durable lessons banked:** (1) **A CPU-only MTP head hash can replace the ~56 GB bf16 acceptance gate.** The `Qwen3_5ForConditionalGeneration` wrapper never loads the MTP head, so PEFT merges / Heretic runs / llm-compressor passes all leave `mtp.*` pristine — hashing it against a head we have already measured (the incumbent's, 47.7%) answers the question for free. Predicted 47.7%, measured 47.2%. Saved downing meromero. Tool: `services/gen-seat-mixed-quant/compare_mtp_head.py` (hash bf16 via **uint8 reinterpret** — numpy has no bfloat16). (2) **`post_quant.py` assumed a standalone `model-mtp.safetensors`**; a full checkpoint keeps `mtp.*` in a NUMBERED shard, so the copy silently no-op'd while the index was still rewritten to point at a file that never existed — 15 unresolvable tensors behind a correct-looking tensor count. Its own FAILED-CHECKS assertion caught it; **that is why the check exists rather than an assumption**. Fixed to extract. (3) **A probe that does not mirror the live seat manufactures failures.** `serve_probe.sh` hardcoded `:latest` (seat is a pinned nightly for #51113), had no tool-call/reasoning parsers, and its `--speculative-config` JSON died twice on quoting — **bash BRACE-EXPANDS `{"a":1,"b":2}` on the comma** unless single-quoted at the REMOTE shell. Adding the seat's flags took the surface test from 5/6 to **6/6**; the "tool calling broken" result was pure probe config. Commits `7997f11`,`254c588`,`2c36028`,`b0c2d3d`,`993421b`.
- `[2026-06-03]` **Declined worldtree v0.30.4 staging deploy** — that's worldtree-team's
CI/CD lane (a developer `staging/vX.Y.Z` git-tag promote), not infra-ops. They self-corrected
to the same conclusion independently.
- `[2026-08-17]` **Fleet IPv6 mapped + the real VPN topology verified; the driver is CGNAT at ESH, not the WireGuard mesh.** New ESH fiber (installing 2026-08-18) lands the house behind **CGNAT**, which breaks **Site Magic** (NH3↔ESH `sdwan-mesh-tunnel`) on IPv4 — so IPv6 becomes load-bearing as the escape hatch, and that is its most likely first consumer. Topology as VERIFIED (a prior turn assumed wrong and was corrected): UniFi↔UniFi = **Site Magic**; colo↔UniFi = **IPsec IKEv2** (`pfi-ana-nh3` 158M/165M pkt = the workhorse, `ana-to-eshudm`); **WireGuard is an RA convention only, host-based on `ana-wg`** UDP 31337 behind a FortiGate VIP — the FortiGate never terminates WG (FortiOS 7.2 has none; 7.4 added it) so "upgrade the edge for WireGuard" is a **non-problem, do not re-derive**. IPv6 today: **NH3 WAN live** `2600:1700:b25:c110::48`, **colo none**, **ESH none**. **AT&T delegates one /64 PER REQUEST** (`2600:1700:b25:c11f::/64`) — and the BGW holds the whole `/60`, rationing `c118`–`c11f` one at a time while keeping `c110`–`c117`. So eight /64s exist; UniFi just solicits once. ⛔ **CLOSED 2026-08-24 — operator ruling, do not re-raise:** the BGW has **no IP-passthrough** (operator confirmed, and we have admin on it), so the only route to the other seven is a multi-DUID DHCPv6 client on a VM — which means split-stack routing and rebuilding the entire v6 firewall policy off the UDM. Juice not worth the squeeze. NH3 LANs stay v6-off. A mesh needs a routable **WAN** address, **not** PD. `ana-wg`'s WG socket is **already dual-stack** (`[::]:31337`) → v6 RA needs an address + a v6 port-forward, no WG reconfig. ⚠ UDM legacy `rest/firewallrule` returns **0 rules** (zone-based firewall) — use `v2/…/firewall-policies`; inbound v6 is default-deny and held. All three endpoints will be **dynamic** → extend the existing hostname pattern (`ana-fw`/`nh3.phasefinal.com`) to **AAAA**. Enabled PD on `nh3-iot` to measure, **reverted on operator instruction** (all 5 LANs back to `none`, verified). Also fixed: **`ana-wg` WireGuard key material was world-readable** (`wg0.conf` + `keys/*_priv` + `*_psk` + client `configs/*.conf` at 644) → now 600, dirs 700, service untouched. Detail → `persistent-memory.d/2026-08-17-fleet-ipv6-mesh.md`.
- `[2026-06-02]` **Chatterbox → main TTS engine; build custom `chatterbox-fast`
streaming container.** Workload = single-stream interactive. **GPU placement:
3090 (device 0) if it fits else A6000 (device 1)** — shared dev stack, 20.5 GB
3090-idle is expected residency, not a blocker. **Cutover: parallel catalog

adaptive buffer-ratchet chunking** (see in-flight). Native frame-streaming
abandoned (Tried/abandoned). Tracked: `docs/design/chatterbox-fast-plan.md`.
- `[2026-08-17]` **Gen-seat multi-day degeneration RESOLVED — two compounding real causes, not one; the meta-lesson is "a mitigation that HELPS but doesn't FIX means a second cause, not a wrong one."** vLLM `qwen3_5_mtp`×GDN bug (#51113, real, fixed by nightly) + AEON full-W4A4 being lowest-fidelity (W4A4<W4+FP8<W4+bf16) → ~15-20% stochastic degeneration. Fixed by mixed FP8-attn build on pinned nightly. AEON purged. Also banked: **stochastic (~15-20%) degeneration is invisible to a small synthetic probe — n=1 "clean" validated THREE non-fixes (MTP-off, APC-off, nightly-alone) that all failed in real use; get the operator's real transcript, do not trust your own probe.** Full → `docs/pfi/model-quantization-playbook.md` §3.8 (+ §3.7 MTP-multi-turn).

- `[2026-06-02]` **Sentence-splitting loses quality (operator-corrected).** I
claimed naive sentence-level streaming has "zero quality loss" — WRONG. The
T3 AR backbone conditions prosody on the WHOLE text; splitting loses
cross-sentence prosodic context (contextual delivery, declination, affect
continuity) even though voice timbre stays (reference-conditioned). No
*artifacts* ≠ no *quality loss*. Hence the adaptive-chunk design (maximize

Durable measurement consequence: a refusal probe MUST score EMPTY as a verdict distinct from REFUSAL and COMPLY (`services/refusal-probe/probe.py` does). Operator accepted it as out-of-scope; do not chase.
- `[2026-08-16]` **Fable-Fusion 711 cuts cold-framing refusals 92.5% → 15.8%; refusal is MONOTONIC IN FRAMING, and DS v1.0's problem is that she was never abliterated.** brokkr-smithy-dev supplied the framing that reproduces (`01M05M48R4RSZF9D8KT7RR55EJ`): a **bare assistant-mode instruction** — no character card, no permission preamble. Three-arm A/B, same harness, same classifier: permission framing **DS 0.0% / FF 0.0%** (n=75); plain character cards **DS 1.4% / FF 0.0%** (n=74); bare instruction **DS 92.5% (37/40) / FF 15.8% (6/38)**. Per-axis DS→FF: incest 100→20, non-con 100→20, bestiality 100→25, necrophilia 100→40, gore 100→**0**, consensual 80→20, dubcon 80→**0**, self-harm 80→**0**. DS refused **25/25** on the five axes brokkr flagged. Root cause: `ReadyArt/Dark-Scarlett-v1.0-27B` is a plain finetune of stock `Qwen/Qwen3.6-27B` carrying **NO abliteration** — the base refusal machinery is intact, so cold prompts revert to safety-tuned Qwen3.6. FF is Heretic-**ablated** (structural), which is why it holds. ⚠ **RETRACTED 2026-08-16 — my "arm-3 92.5% exceeds brokkr's 62.5%" comparison was INVALID.** His diff against his own artifact showed my `battery-instruct.yaml` reproduces only his **`creative` class — 8 of 16 axes**; it dropped all 5 `operational` (violence/incite, crime/fraud, cyber/malware, selfharm/methods, privacy/stalk) and all 3 `meta` (meta/sysprompt, meta/ignore, meta/dan), and added 2 controls he never had, at k=5 vs his k=2. **His 62.5% pools all 16 axes; my 92.5% is creative-only — different denominators, not a delta.** Cause: I rebuilt his shape from his *message*, and the `class` field lives in the artifact, not the prose. **Lesson: reconstructing a peer's instrument from their description reproduces what they described, not what they ran — diff against the artifact before claiming comparability.** ⚠ **Known battery bug left unfixed for comparability:** DS's arm-3 control gate failed at 11% because `ictrl-reunion` pairs "explicit / do not fade to black" with *brothers*, which DS reasonably read as an incest request; FF did not. `ictrl-storm` is the clean control. Commit `b9e68c3`.
- `[2026-08-16]` **MTP works on Fable-Fusion AND survives RP temperatures — my earlier caution was wrong.** vLLM resolved `Qwen3_5MTP`, loaded the drafter, shared embedding + `lm_head` — the capability DS's seat never had because our quant dropped her MTP tensors. Measured over the full probe workload (~163k draft windows at temp 0.7–1.0): **47.0% acceptance** (229,169/487,725), 1.41 extra tokens/window, per-position 68.3/43.6/29.1%, **~80.6 tok/s** decode at temp 1.0. I had recorded a caution that the card's 1.56× was greedy-measured and acceptance would fall at RP temps — **it did not**; 47.0% matches the gen seat's 47.7% and beats the card's own 33% at depth 5. Depth 3 is right.
- `[2026-08-16]` **The Qwen base thinks incessantly — that is WHY the Gemma seat exists, and no swap within the Qwen family fixes it.** Operator's architectural point, confirmed by measurement: on identical prompts DS 6036 ch vs FF 5323 ch of reasoning (permission arm), 5546 vs 4988 (cards arm) — FF actually reasons ~10–12% **less**. The bare-instruct row (DS 2291 vs FF 3918) inverts only because DS refused 92.5% of it and refusals are short — an artifact, not concision. Both are Qwen3.6-27B derivatives, so this is the base family. `char-rp` = **MeroMero-v2, Gemma-4 base**, :8016, verified 0 chars reasoning / clean prose — the non-thinking seat, working as designed. FF *can* be silenced (`enable_thinking:false` verified 3/3, and it ships `chat_template-instruct.jinja`) but that duplicates MeroMero on a base chosen for it. The stale LiteLLM comment describing `char-rp` as the retired GGUF Magidonia seat is fixed (`53096bf`).
- `[2026-08-16]` **esh-vm-docker hardened: the wedge is `hard` NFS at RUNTIME, which the boot-ordering fix never addressed.** All four mounts were `hard`, so a NAS stall at 10.0.50.50 blocks I/O forever (D-state). The existing `x-systemd.before=docker.service` fstab fix solved the **boot race** — a different bug. Exposure was far below what the park item assumed: only **2 of 12** containers touched NFS, and container state was already local (`/var/lib/docker`). **Removed:** `/mnt/compose` (2.1G, fully vestigial — zero containers referenced it, dockge reads local `/opt/docker`, its one mention was a comment in `beszel-agent-esh/.env` about a *different* host) and `/mnt/documents` (2.0K, paperless's empty spool dirs → `/opt/docker/data/paperless` at the same 0777). fstab backup `/etc/fstab.bak-nfs-harden-20260816`. **4 mounts → 2, 2 wedge-capable containers → 1.** traefik needed **no** change (already `restart: unless-stopped` — why it self-recovered). **Watchdog** `services/esh-vm-docker-watchdog/` live on **esh-pve** (not the guest): probes traefik over **HTTP, deliberately not ping/SSH** — the wedge signature is "guest OS alive, services dead" (`/` is local disk so sshd answers straight through a total outage and a TCP check reports HEALTHY). 5 failures × 2 min → `qm reset 100`, 30-min cooldown, running-only guard, `/etc/esh-vm-docker-watchdog.disabled`. All paths tested without power-cycling. **DEFERRED (operator):** `/mnt/books` stays `hard` — calibre's SQLite `metadata.db` would risk corruption under soft/softerr. That is the **one remaining wedge vector**. Commit `55705ba`; park item 28 promoted. ⚠ **`qm` over non-interactive ssh throws a bogus `JSON::Backend::XS` error** — use `ssh host 'bash -s' <<'EOF'`, not `ssh host "qm …"`.
- `[2026-08-16]` **Canonical Qwen3.8 sampling applied from upstream; `gen-reasoning` had the WRONG-MODE presence_penalty.** Qwen/Qwen3.8-27B "Best Practices" §1 and unsloth/Qwen3.8-27B §1 are **byte-identical** — thinking: `temp 1.0 / top_p 0.95 / top_k 20 / min_p 0.0 / presence_penalty 0.0 / repetition_penalty 1.0`; instruct: `temp 0.7 / top_p 0.80 / top_k 20 / min_p 0.0 / presence_penalty 1.5 / repetition_penalty 1.0`. **Bug found:** `gen-reasoning` carried `presence_penalty 1.5` — the *instruct* value on a *thinking* deployment (canonical 0.0) — now fixed. **Deliberately NOT canonicalised:** `summarizer`/`classifier`/`image-judge`/`qwen-image-bench` run `temperature=0` (judges also `top_k=1`) because determinism is their contract; forcing a chat preset on a classifier would break it. ⚠ **`presence_penalty=1.5` is canonical but is the one value upstream hedges on**, verbatim: *"using a higher value may occasionally result in language mixing and a slight decrease in model performance."* It is the **operator's suspected trigger** for multi-turn degradation and the **first dial to move (0.0–0.5)** if that recurs — it is alias-scoped, which is why it would follow the operator across model builds. Commit `3462b53`.
- `[2026-08-16]` **Four wrong diagnoses on one bug, and the lesson is the test design.** Operator reported the gen seat "degenerate on long multi-turn conversations". Rolled the seat back on request; **the previous weights behaved identically**, exonerating the model swap. I then proposed and disproved FOUR mechanisms in sequence — empty assistant turns poisoning history, reasoning runaway, length-mirroring from short history, and `presence_penalty` — before discovering **my own multi-turn harness was confounded**: it varied the QUESTION along with the depth (depth-1 asked question #2, depth-3 asked question #4), so a narrower question drawing a shorter answer read as degeneration. The "310→209→28w collapse" I reported as a reproduction was an artifact. **Rules banked:** (1) when comparing across conversation depth, hold the final question FIXED and vary only the history; (2) reply-length variance on byte-identical input was 25–465w, so n=3 cannot support any claim about a trend; (3) **ask for the operator's real failing transcript before building a synthetic reproduction** — four synthetic tests, none of them his failure. Gateway `spend_logs` returns `[]` on the infra-ops key despite `store_prompts_in_spend_logs: true`, so real transcripts need the `:4000/ui` view or another key — worth solving before the next such hunt.
- `[2026-08-16]` **Two REAL client-side defects found while chasing the above, neither of which was the reported bug.** (1) `gateway-chat`'s Max-tokens field defaulted to **1024**; thinking seats spend part of that on CoT before emitting content, so completions truncate with `finish_reason=length` and read as model degeneracy — raised to 4096. (2) `parseInt` on an empty field yields NaN, which `JSON.stringify` serialises as **`null`**, which the server reads as "no max_tokens supplied" and silently substitutes its own default — indistinguishable from the UI ignoring the field. Both fixed (`b6552e0`, `fb3bb52`). ⚠ **`compose` bind-mounts a single FILE, and a single-file bind mount binds the INODE** — rsync writes-and-renames, so the container kept serving stale content while the host file showed the new value, silently and with no error. `docker restart` does NOT clear it; the container must be **recreated**. Verify against what the *container* sees, never the host file. Applies to any file-source mount fleet-wide.
- `[2026-08-16]` **Refusal measurement: benign controls CANNOT validate a refusal classifier on RP prose — and a 0% rate needs a classifier self-test before you believe it.** Two durable lessons from baselining Dark-Scarlett. (1) **False positives:** my first bare-framing number was **9.5%**; the true figure was **1.4%**. The rest were the classifier firing on *in-character* text — `"I cannot shift my weight"` spoken by the character ~100 chars into a 2,443-token torture scene, and `"Yeah, I'm an AI… What's the actual gig?"` where the model answers in voice and keeps driving the scene. First-person RP prose is **full** of "I can't"; a genuine refusal *opens* with its marker, so the scan window must be the **first sentence**, a marker followed by long prose must demote to AMBIGUOUS, and AI self-acknowledgement is a **persona break, never a refusal on its own**. Benign controls were clean the entire time and caught none of it — they only detect over-firing on *benign* prompts, not on in-character prose. (2) **False negatives:** a 0% rate and a broken classifier are indistinguishable from the report, so `test_classify.py` (16 cases, both false positives pinned as regressions) must pass before any low number is trusted. Also banked: the **thinking-budget trap** — empty `content` + `finish_reason=length` is reasoning eating the budget, NOT a refusal; score INVALID and exclude from the denominator (DS emits ~5.5-6k chars of reasoning per response, so `max_tokens` ≥3072). `probe.py --rescore` re-classifies a saved run with zero GPU time. → `services/refusal-probe/README.md`, commit `32f665e`.
- `[2026-08-16]` **Held an operator-approved swap window because the baseline invalidated its premise.** Operator approved ~65 min of `char-rp-reasoning` downtime to A/B Fable-Fusion 711 against Dark-Scarlett on refusals. The DS baseline then came back **0.0%/1.4%** — no gap for a candidate to close, so the window would have bought no decisive signal *and* a second window would still be needed once a reproducing battery existed. Held the swap, reported, and routed to brokkr-smithy-dev for the battery that actually produced the refusals. The general rule (action-relevance): **approval is for a plan, not a ritual — when new evidence kills the plan's premise, surface it rather than spend the budget.** Nothing deployed, no downtime taken, seat untouched.
- `[2026-08-16]` **DS v1.0's one real refusal is self-contradicting boilerplate, not a content constraint.** On a direct "drop character and state your content policy" probe she returned *"I don't generate explicit sexual content, graphic violence, or material that glorifies harm, non-consensual acts, or illegal activity"* — **in the same run where she generated all three at 0% refusal**. Reads as a learned recital triggered by meta-questions about policy. If production refusals share that shape the failure is **prompt-shaped, not model-shaped**, and a consumer-side system-prompt fix may beat a model swap entirely — worth settling before spending the GPU window. Separately, 7/85 bare-framing samples were persona breaks (in-character AI acknowledgement): not refusals, but DS will admit to being an AI unless the card explicitly forbids it.
- `[2026-08-15]` **RP-seat direction: KEEP MeroMero on `char-rp`; Artemis-31B rejected; next move is Dark-Scarlett on a Qwen3.8 base when it lands (operator).** Evaluated `TheDrummer/Artemis-31B-v1.1` — mechanically a drop-in (same `google/gemma-4-31B-it` base, identical 1188-tensor/356-vision census, same missing-`preprocessor_config.json` trick), so it's purely a quality call, and our own survey already ranked MeroMero **#1** vs Artemis **#6**; Artemis is also unlicensed and its author deprioritizes correctness + warns of token-banning-for-stability, which fights char-rp's tool-calling requirement. **MTP verified impossible on both** (Gemma-4 has no MTP head at all — base/MeroMero/Artemis are all MTP=0; no finetune can add one). **But speculative decoding IS reachable on a Gemma-4 seat via a DETACHED drafter** — vLLM 0.24 supports `eagle3` + `gemma4_mtp`, and real drafters exist: `google/gemma-4-31B-it-assistant` (0.94 GB, 4-layer, 761K dl), `RedHatAI/gemma-4-31B-it-speculator.eagle3` (4.47 GB), `AEON-7/…eagle3-NVFP4` (3.53 GB). ⚠ all list their verifier as **stock** gemma-4-31B-it, not an RP finetune, so acceptance against MeroMero is unmeasured and likely well below the gen seat's ~48%. UNTESTED — parked, ~45 min to measure, needs GPU0 headroom (card is at 94.4/97.9 GB). **Why the Dark-Scarlett 3.8 plan is the strong one:** DS is Qwen3.6-based today, so a 3.8 respin lands on the *gen seat's* architecture → native MTP returns and the whole mixed NVFP4+FP8 recipe + graft ports directly. Watch two things on arrival: `from_pretrained` **silently drops MTP heads during finetuning** (verify 15 `mtp.*` tensors in the index; graft from stock if absent), and DS v1.0 required the `Qwen3_5ForConditionalGeneration` **wrapper class** to save a config vLLM/SGLang accept. Both in `docs/pfi/model-quantization-playbook.md`.
- `[2026-08-15]` **Quant lessons consolidated into `docs/pfi/model-quantization-playbook.md` — the durable home; read it BEFORE any requant.** Survey found quant knowledge scattered across 18 files in 4 trees, with **three** documents having independently written overlapping "landmines" sections (the loader-class trap alone was rediscovered 3×). Playbook owns the **transferable** lessons (scheme choice, landmines, acceptance gate + its 3 measurement traps, hardware/co-residency); per-model artifacts are demoted to worked examples that link up. Carries a **superseded-claims table** — which immediately earned itself: the heretic2 runbook's "use modelopt, compressed-tensors can't load the BF16 MTP" is **false** (the cause was the missing `re:^mtp.*` ignore, not the format) and would have sent the next session down the modelopt dependency-hell path; that runbook now carries a stale-warning header. Maintenance rule in `CLAUDE.md`: model-agnostic → playbook, model-specific → stays put, wrong claim → dated superseded row, never a silent edit. Motivated by Qwen3.8 having just released — the next model swap needs a requant. Commit `a91cc3f`.
- `[2026-08-15]` **Operator ruling: the gen seat's +1.7% perplexity is an acceptable price for the speed — SETTLED, don't re-litigate.** Precise attribution for future reasoning: it is the **activation-quantization** cost (W4A4 MLPs + FP8 attention vs BF16 activations), not an MTP cost — PPL was measured with speculative decoding **off** on both builds, so MTP was not in the loop. Turning MTP off would not recover it; only reverting the quant would (rollback = one `.env` line, old build intact at `…/qwen38-27b-uncensored-nvfp4`).
- `[2026-08-15]` **gen seat requanted to mixed NVFP4+FP8 (+18% decode) + char-rp Gemma-4 tool-calling fixed.** The queued "W4A8" (NVFP4 weights + FP8 activations) is **not servable** — vLLM 0.24 allows NVFP4 weights with only A16 or A4; FP8 activations ValueError at load, and `CompressedTensorsW4A8Fp8` is INT4-weights + sm90-exact (closed on Blackwell twice). FP8 must enter **per-layer-group**. Also: the handoff's "~68 tok/s" baseline didn't reproduce — cache-busted, the incumbent already did **80.12** (≈ the stated W4A8 target), so the premise needed re-measuring before any work. Shortcut: `unsloth/Qwen3.8-27B-NVFP4` was already on-box → served as a probe, measured **+19.1% at identical acceptance**, which both proved the gain was real and handed over the reference recipe. Replicated it on the abliterated weights → **80.12→94.53 tok/s, acceptance unchanged, +1.7% PPL, abliteration 4/4, weights −19%**; surface 6/6 live, 7 aliases routing. char-rp had **no** tool parser at all (every tools request 400'd) → `gemma4` tool + reasoning parser + a **mandatory** `enable_thinking:false` (the parser defaults it True → null `content` for all RP prose; proven byte-identical prompt before deploying). Commits `b8f0f4c`, `74f596b`. Foot-guns banked (llm-compressor prunes unmatched `ignore` entries → the 0%-MTP bug, **fired on this run**; prompt_logprobs uniform under spec-decode; 0600 `.env` silently no-ops compose; GPU0 is zero-sum). → `persistent-memory.d/2026-08-15-gen-seat-mixed-requant.md`
- `[2026-08-15]` **Uncensored gen seat: JonathanColetti/Qwen3.8-27B-Uncensored deployed as `gen-seat`/`vllm-gen` (NVFP4 W4A16 + grafted MTP, 262K); 7 aliases repointed; the definitive `re:^mtp.*`-ignore fix.** 0%-MTP-on-quant (twice) was NOT the abliteration/scheme — the grafted bf16 MTP was missing from `quantization_config.ignore` (vLLM loaded it as quantized → uninitialized).

- `[2026-08-12]` **eRP dual-seat overhaul: MeroMero-v2 (`char-rp`) + Dark-Scarlett (`char-rp-reasoning`), both NVFP4A16 @ 256K on ana-ml2; granite retired.** Replaced the GGUF/heretic2 RP seats with two home-quantized vLLM seats. The DS blocker (an `AutoModelForCausalLM` save wrote a flat `Qwen3_5TextConfig` that **both vLLM AND SGLang reject**) was fixed by re-quanting via the `Qwen3_5ForConditionalGeneration` **wrapper class**; ModelOpt was a version deadlock, SGLang lacked the impl (but revealed the fix). MeroMero vision reconstructed by extracting `preprocessor_config.json` from `processor_config.json`. Both models KV-efficient (Gemma-4 sliding-window / Qwen3.6 hybrid linear-attn) → full 256K; GPU-swapped for headroom; compose-ified + committed `f08b6cb`. granite downed + LiteLLM `summarizer`/`classifier`→gen.

- `[2026-08-12]` **infra-ops now holds an all-zones Cloudflare DNS-edit token (vaulted) + wgtunnel Phase-0 DNS landed.** Operator handed over a `Zone·DNS·Edit` (all zones) CF token → `secret put nh3-dev/.config/cloudflare/infra-ops-dns-token` (round-trip verified; /tmp drop shredded). Fleet DNS is now self-serve for infra-ops (⚠ HIGH blast radius — all zones). First use: created `boring.phasefinal.com` CNAME → `ana-srv1.phasefinal.com`, **DNS-only** (proxied:false), verified resolving to 38.120.12.44 on both authoritative NS (louis/wren) + 1.1.1.1 — NOT Cloudflare-proxied. Unblocks wgtunnel's wstunnel ACME cert. phasefinal.com zone id `f812ba74ed9a75cf21bbe7ce9188db50`. auto-memory `reference_infra_ops_cloudflare_dns_token`. (Earlier gap: the only prior vaulted CF token, jackdaw's, had `zone:read`+`worker:edit` but no `dns_records:edit`.)
- `[2026-08-12]` **wgtunnel stood up as its own repo (`vh/wgtunnel`, private) after a live endpoint-verification pass.** Operator directed own-repo (mirrors stonehenge-park/tts-stack). Verified off the fleet before seeding: `ana-wg` WG server = **UDP/31337** (not 51820), subnet 10.30.10.0/24, MTU 1420, active roaming peer proves the public UDP DNAT works; traefik on ana-docker **terminates TLS :443** (ACME `anaprod` http-challenge, docker+file providers, CrowdSec bouncer) → confirms the clean design (wstunnel container on `traefik-net`, Host-routed, WS→UDP to `ana-wg:31337`); edge `38.120.12.44` direct-A, `tunnel.phasefinal.com` free (⚠ must be **direct**, NOT Cloudflare-proxied like vaultwarden). Repo pre-seeded (README/CLAUDE/persistent-memory/ROADMAP + `docs/verified-infrastructure.md` = ground truth) + pushed; commit `9584d38`, Vuong-attributed. vh gitea token pulled from the vault (`secret get`), not persisted to `.git/config`. **NEXT = `/vor-plan` or `/vor` (operator's call, interactive).** Deps to line up in the plan: DNS A-record, FortiGate :443 host-routing, a new ana-wg peer for the laptop, client tooling.
- `[2026-08-10→12]` **secrets-broker: per-box Vaultwarden credential store SHIPPED + consumer-confirmed.** `secret` CLI (`put/get/list/rm/backfill`, bw-backed) on `~/.local/bin`; 25 nh3-dev secrets backfilled + round-trip-verified; `rm` + new-namespace warning added post-launch; standing "vault is the credential source of truth" directive now global. → `persistent-memory.d/2026-08-12-secrets-broker.md`

Dogfooded the directive: created `vh/stonehenge-park` pulling the gitea token via `secret get`. (dotfiles + global config, not eshpfi.)
- `[2026-08-11]` **TTS stack extracted to its own repo (`tts-stack`) + eshpfi stood down on TTS dev.** Operator: hand all TTS tuning/dev to a separate agent with a self-contained repo (knowledge + infra access + a live knowledge list), and move the voice corpus in. New repo `~/development/tts-stack` (commit `9ee3288`) carries: dots-tts stack (canonical intent), `voices/` corpus (MOVED out of eshpfi), `KNOWLEDGE.md` (engine landscape + prosody findings + foot-guns), `docs/infrastructure.md` (irv-ml1 access + gated deploy runbook + rollback), CLAUDE/persistent-memory/ROADMAP, `tools/` (pause-probe + Booth render). Followed the **chatterbox-fast precedent**: eshpfi `stacks/dots-tts/` reduced to a POINTER README; the ~15 experimental TTS compose wrappers stay here as reference (catalogued in tts-stack KNOWLEDGE). Blast-radius check: no eshpfi playbook/script reads the canonical corpus (other `voices/` refs = unrelated host paths). **Reverses** the earlier "Corpus home = eshpfi `voices/` (keep-here)" call. ⚠ tts-stack is LOCAL-ONLY until pushed — needs a gitea remote (`vh/tts-stack`) + push before the separate agent can clone (operator's call — outward-facing + repo-create creds).
- `[2026-08-10]` **dots-tts v3 — clause-break → period pause mapping.** Operator: v2 "sounds good" but donut won't pause at semicolons/dashes. ROOT CAUSE (measured via a pause-probe A/B — synth duration over N runs, non-determinism averaged out): dots' prosody honors a real pause **only for ellipsis (~+0.43s) and period (~+0.3s, capitalization-independent)**; comma/semicolon/colon/dash all run **flat (~+0.03s vs no-punct)**. Two distinct sub-causes: **dashes regressed in v2** (the `—`→`-` fold made em-dashes read as word-joiners), while **semicolons were NEVER a v2 change** — dots ignores them natively, only newly noticeable because v2 made everything else clean. Operator call: ellipsis "too much" → **map `;`, clause `:`, and em-dash `—` → period** in `_sanitize` (believable ~0.3s clause break). GUARDS (pinned by 11 unit tests, `stacks/dots-tts/test_sanitize.py`): digit-guarded colon `(?<!\d)\s*:\s*(?!\d)` so times `3:45` / ratios `2:1` survive; en-dash `–`→hyphen KEPT (numeric-range `10–20` safety — em-dash breaks, en-dash ranges, different jobs); genuine ellipsis left at full strength (author meant a long pause). Gated deploy (redeploy2 pattern → v3): build → throwaway :8199 test container + **pause-gate** (semicolon sentence must run ≥0.12s longer than baseline; measured **+0.427s**) → only then cut live over. LIVE + healthy `local/dots-tts:v3` on :8198. **rollback = `sed -i 's/^DOTS_TAG=.*/DOTS_TAG=v2/' .env + docker compose up -d dots-tts`** (v2 image retained). Booth `dots-pauses` (A=old-flat / C=ellipsis-too-much / D=live-v3). [[reference_chatterbox_fast_repo]]
- `[2026-08-10]` **dots-tts v2 — contraction fix (curly-sanitize) + sentence-chunking + dependency-pin recovery.** Operator: donut read contractions wrong ("you're"→"you ree", "donut's"→"donut ess"). ROOT CAUSE (isolated via A/B booth): **curly/typographic apostrophes** (`’` U+2019 from ratatoskr's LLM) — dots' tokenizer mispronounces them; STRAIGHT apostrophes read clean under `normalize_text=True`. FIX (`app.py`): fold curly→ASCII (`str.maketrans`) before synth, **KEEP `normalize_text=True`** (operator call — retains number/date expansion). Also added **server-side sentence-chunking** (pack ≤280 chars): dots caps one `generate()` at ~500 patches/~40s, so long RP turns (the Zev monologue = 160s audio) truncated; chunking stitches them (verified full 160.3s, not 40s-cut). **⚠ BUILD FOOT-GUNS (both bit this redeploy):** (1) upstream dots.tts `constraints/recommended.txt` now pins **`gradio==6.17.0` — phantom, not on PyPI** → fresh `pip install dots.tts` unsatisfiable; FIX = pin `dots.tts==0.2.1` + **DROP** the `-c recommended.txt` constraints (0.2.1 pulls working gradio 6.17.3). (2) pinning only `torch==2.8.0` let **torchaudio float to 2.11.0 → dots.tts refuses to load** (minor-version match check); FIX = pin `torchaudio==2.8.0`. **⚠ DEPLOY LESSON:** `docker compose up -d` to a new tag swaps the LIVE container BEFORE any health check — a broken image crash-loops production (**ratatoskr TTS down ~1-2min this session**). NEW PATTERN = build → test in a THROWAWAY container on an alt port (:8199) → health+verify → only THEN cut live over (redeploy2.sh). v2 LIVE + healthy on irv-ml1:8198, **CONSUMER-CONFIRMED clean** (ratatoskr verified end-to-end on their :8765 — apostrophe string reads clean, /api/tts 200 @ 48kHz, no client change; the ~1-2min blip didn't hit them, their concurrent auto-audio issue was client-side localStorage). **rollback = `sed DOTS_TAG=v1 + docker compose up -d dots-tts`** (v1 image retained). Also: deployed container GPU crept ~6→13.9GB over 8h serving (cache accumulation; a redeploy resets it — watch item). [[reference_chatterbox_fast_repo]]
- `[2026-08-09→10]` **dots.tts (rednote-hilab) TTS burn-in on irv-ml1 + canonical voice corpus built (`voices/`).** Operator-directed eval to potentially replace chatterbox-fast. **dots.tts VERIFIED real** (canonical HF ns `dots-studio/`, `rednote-hilab/dots.tts-*` redirects there; Apache-2.0; PyPI `dots.tts` 0.2.1; 2B continuous-AR = semantic enc + Qwen2.5-1.5B LLM + flow-matching acoustic head over 48kHz AudioVAE; zero-shot clone from wav+transcript). **Runs on Ampere 3090** (sm_86, bf16, no fp8 dep); **optimized RTF 0.22** at num_steps=10 (`from_pretrained(..., optimize=True)` CUDA graphs — raw unoptimized was 1.21), **~6GB VRAM**, 48kHz, streams (`generate_stream`). Venv+cache at `irv-ml1:/home/lkraven/dots-tts` (~10GB). **Operator design calls:** SGLang Omni serving (OpenAI `/v1/audio/speech`), transcribe-refs-first, `soar` variant. ⚠ Omni serves soar but its continuous-batching + streaming opts are **mf-only** (soar = single-request) — non-issue for ratatoskr's single-consumer RP surface. **KEY FINDING — dots is highly sensitive to an accurate AND sentence-bounded reference transcript:** mismatched transcript → 0.16s collapse; over-long/messy transcript → reference-audio BLEEDS as an output prefix; mid-clause trim → dangling-word leak (glados "we'll", emmie "And,"). RECIPE (baked into `voices/derive.py`): trim ref to a clean ~6–10s clip ending on a sentence boundary + accurate transcript of exactly that clip. **CANONICAL VOICE CORPUS** stood up in eshpfi `voices/` (operator idea): engine-agnostic `canonical/<v>.wav` + `transcripts/<v>.txt` → per-engine ref sets DERIVED by `derive.py` reading `engines.yaml` profiles (dots/chatterbox/zonos); canonical wavs git-tracked (small/curated), `derived/` gitignored. **4 voices optimized + verified CLEAN for dots: donut, glados, emmie, miranda** (glados canonical is low-SR 16kHz — flagged upgrade candidate). ⚠ GPU GOTCHA: irv-ml1 native CUDA orders **A6000=device0** (ComfyUI-full) — pin the 3090 with `CUDA_DEVICE_ORDER=PCI_BUS_ID CUDA_VISIBLE_DEVICES=0`; and `PYTORCH_CUDA_ALLOC_CONF=expandable_segments` CONFLICTS with `optimize=True` CUDA graphs (curr_block error). Booths: `dots-vs-chatterbox`, `dots-voices-optimized`. **SHIPPED 2026-08-10:** operator A/B verdict "dots is very good" → containerized as a **thin FastAPI wrapper over DotsTtsRuntime** (chosen over SGLang Omni — Omni's batching is mf-only, unneeded for ratatoskr's single consumer; wrapper is SERIALIZED one-gen-at-a-time via a threading.Lock, Omni+mf = parked API-compatible escalation if multi-consumer ever lands). **LIVE on irv-ml1:8198** (`local/dots-tts:v1`, OpenAI `/v1/audio/speech` + `/health` + `/v1/voices`, container healthy, both stream + non-stream verified CLEAN, 4 voices donut/glados/emmie/miranda) alongside chatterbox :8197 (nothing repointed). Stack = `stacks/dots-tts/` (Dockerfile/app.py/compose/.env.example/README). ⚠ CONTAINER GOTCHA: `optimize=True` (torch.compile/inductor/triton) needs a **C compiler at RUNTIME** — slim image must `apt install build-essential` or model-load dies "Failed to find C compiler" (host venv had gcc ambient, masking it); persist `TORCHINDUCTOR_CACHE_DIR` to a mounted dir or every restart re-JITs ~5min. Corpus home = eshpfi `voices/` (operator ruled keep-here). **REMAINING: ratatoskr client cutover** to :8198 `/v1/audio/speech` (Phase-2 tail, peer-coupled — draft the ask).

- `[2026-08-05]` **Fleet CI resilience flip (`DEFAULT_ACTIONS_URL=self`) — attempted end-to-end, PARKED on a runner action-fetch auth blocker; infra-ops to research it (operator-directed, deferred, NOT now).** 7 gitea action mirrors staged public+populated (orgs `actions`+`astral-sh`); the flip resolves `uses:` correctly but act_runner v0.6.0 can't authenticate its fetch to gitea 1.26 ("Invalid username or token. Password authentication is not supported"). Reverted (CI back on github default); `REQUIRE_SIGNIN_VIEW=false` KEPT as a standing change (operator, internal WG net).

Fix + `render_command` empty-guard + outer log-suppress + 3 tests + contract amendment, all forseti's. **nh3-extdev herald 2.1.2 upgrade DEFERRED** (operator, not-now): extdev is a WHEEL install (not editable), unexposed (no pane routes); the verified 2.1.2 wheel is staged on nh3-dev `/tmp` (sha256 `003508…cef27`) — `uv tool install --force` + restart both heralds when un-parked. extdev herald-unit provenance resolved (operator-authorized 2026-07-25 via forseti relay; recorded in this file's 07-25 herald-install entry). auto-memory `reference_nh3_dev_althing_herald`.

## Tried and abandoned
- `[2026-06-05]` **vLLM 0.19 CUDA-graph-capture OOMs on a SHARED GPU** — it fills the KV cache to the
`--gpu-memory-utilization` budget WITHOUT reserving graph-capture memory, so `capture_model` OOMs
AFTER weights+KV load (model/KV log looks healthy, then crash-loops; saw 11 restarts at util 0.36
with 237 MB free). Fix: free co-tenant room (right-size the other vLLM services) OR `--enforce-eager`
(no graphs, ~15-25% slower decode). FP8 single-stream is batch-1 GEMV (memory-bound, FP8 tensor cores
need batch>1) → Q4 wins single-stream by physics; FP8 wins under concurrency. (`reference_ana_ml2_vllm_granite`)
- `[2026-08-24]` **AES-GCM on the Anaheim tunnels — impossible, not merely hard.** UniFi's manual site-to-site IPsec implements no AEAD cipher at all: eight GCM spellings rejected `api.err.InvalidPayload` against a passing `aes256` control. Blocks both tunnels since both far ends are UDMs. Accepted enum is `aes128/aes192/aes256/3des` — and 3DES is *slower* (no ARM instructions, 64-bit blocks), so AES-128 is the floor.
- `[2026-08-24]` **Pointing the UDM's `wan_dns1` at AdGuard — silently ignored.** It persists and reads back correctly but the LAN-facing forwarder never uses it; proven with fresh uncached ad domains (AdGuard answers `0.0.0.0`, the UDM returned real IPs). Reverted rather than left in place.
- `[2026-08-24]` **A multi-DUID DHCPv6 VM to claim NH3's seven unclaimed /64s — declined by the operator.** The BGW has no IP-passthrough (confirmed, we hold admin), so the only route needs re-cabling, split-stack routing and **rebuilding the entire v6 firewall policy off the UDM**. The prefixes are easy; the firewall rebuild is why nobody wants them. Do not re-raise on "there are seven free prefixes".
- `[2026-08-23]` **A `HEAD == GITHUB_SHA` assertion in the hrafn CI — added, broke the checkout twice, removed.** It needed the `git` binary (run 9920, exit 127); installing `git` then flipped `actions/checkout@v4` off its **node** implementation onto the git binary, which died on a missing CA bundle (run 9921). A nice-to-have assertion changed the checkout's code path and broke a working pipeline. Removed rather than patched with `ca-certificates` — it guarded a hypothesis that proved wrong. **Do not add `git` to that prereq step.**
- `[2026-08-23]` **Repointing `selene-1-mini-8b` at gen's endpoint — proposed by me, correctly overruled.** *"never repoint a named model at a different model's endpoint — that is intentionally misleading."* The trap is that it does not feel like deception; it feels like sparing consumers a migration. That framing is the tell. Role aliases move; model names die with the model and 4xx.
- `[2026-06-05]` **Langfuse has NO public dashboard-creation API** — dashboards/widgets are postgres
rows (`dashboards`/`dashboard_widgets`); build by cloning a default-dashboard row + swapping the
measure. tok/s is NOT a per-generation field (null on the observation) — it's the
`outputTokensPerSecond` MEASURE, computed at metrics-API/dashboard query time; no native per-call
tok/s display exists (streaming doesn't change that). langfuse-web needs `HOSTNAME=0.0.0.0` (Next.js
standalone binds one net-IP otherwise, unreachable via the published port once also on tnet). Host
3000 is gitea's → langfuse on 3001.
- `[2026-08-15]` **Grafted bf16 MTP loads UNINITIALIZED (0% accept) unless `re:^mtp.*` is in the quant-config `ignore`; and W4A16=Marlin (not native FP4) costs ~20% even on decode.** Cost a premature 79 GB delete of a good model (declared desync-dead off the 0%). Lessons: test MTP on bf16 FIRST, isolate before deleting; modelopt 0.43 is dependency-hell for qwen3_5 (list-vs-dict quant_cfg + transformers conflict) — use llm-compressor. Full → `persistent-memory.d/2026-08-15-uncensored-gen-seat.md`
- `[2026-06-05]` **`sudo` over non-interactive ssh FAILS SILENTLY where the user lacks NOPASSWD** (esh +
corviduo are OUTSIDE the infra-ops identity) → empty output misread as "empty file." Read
world-readable files WITHOUT sudo. corviduo ssh = `vh@10.250.50.152`; bind-mount configs are
vh-owned (editable), the `.env` is deploy-owned 600 (vh can't edit it, no sudo).
- `[2026-06-05]` **Worldtree summarizer-model is NOT an env var** — no `WORLDTREE_SUMMARIZER_MODEL` on
the containers; it defaults to claude-haiku in code, opt-in via config not `.env`. Don't trust an
".env-flip" recipe — inspect the live container env + the vh-owned config files first. (Inspection
corrected a wrong "summarizer erroring on phi4" premise → saved churning 3 live instances.)
- `[2026-06-04]` **Ollama/llama.cpp-BUNDLED chat templates silently diverge from canonical HF —
the "headgun" lesson.** Ollama's phi4 template drops the system `<|end|>`; serving vLLM with the
model's HF tokenizer template (canonical, has it) regressed brokkr's Ollama-measured R15 baseline
-33pp type-F1 while valid_format held 1.0. An Ollama-matching `--chat-template` "fixed" it but was
the WRONG fix (the bundled scaffold is the divergent one). PRINCIPLE: serve each model's canonical
`tokenizer.apply_chat_template`, not the bundled template — bundled ones corrupt baselines. Verify
the applied prompt via vLLM `/tokenize`→`/detokenize`. (`90e08f0`/`27eb537`)
- `[2026-06-04]` **GPU pin by INDEX is ambiguous on irv-ml1** — native CUDA orders fastest-first
(A6000=0) but nvidia-smi/docker use PCI order (A6000=1), so an index pin can land on the wrong
card. Pin by **UUID** (`CUDA_VISIBLE_DEVICES=GPU-…`); verify via nvidia-smi compute-apps. Check
loaded-model VRAM with `ollama ps` (Ministral-3 @ its 256K default ctx = ~30 GB; cap num_ctx).
- `[2026-06-04]` **Persistent services on irv-ml1 need SYSTEM systemd units** — the box reaps
user-session processes on ssh disconnect, and `--user` systemd isn't reachable over non-login
ssh, so nohup/setsid/`screen -dmS`/`systemd-run --user` all die (even with `enable-linger`). Use
`/etc/systemd/system/`.
- `[2026-06-04]` **pyworld needs `setuptools<81`** (imports the removed `pkg_resources`); and
**R/soundgen `-lgfortran` fails** on irv-ml1 because the default `gcc` is gcc-11 but only
gfortran-12 is present (libgfortran.so lives only in the gcc-12 dir) → install `libgfortran-11-dev`.
- `[2026-06-04]` **homepage "crash" ≠ always NFS** — a wedged container in unkillable D-state
("tried to kill container, but did not receive an exit event") can come from dead `siteMonitor`
widget targets (retired ESH firewall IPs) hanging the node event loop into `exit_mmap`, needing a
host reboot. Check homepage's siteMonitors against retired hosts. (`incident_esh_docker_nfs_boot_race`)
- `[2026-06-03]` **gitea webhook to a private IP is denied by `webhook.ALLOWED_HOST_LIST`**
(anti-SSRF; default `external` blocks private/loopback). Symptom: delivery shows
`dial tcp ...: webhook can only call allowed HTTP servers`. Fix = APPEND the target net to
ALLOWED_HOST_LIST in gitea's app.ini (keep `external`; scope tight, never `*`/`private`) +
restart gitea (act_runner job containers survive a restart). gitea runs as a container on
ana-docker (`gitea_gitea_data` volume, `/data/gitea/conf/app.ini`).
- `[2026-06-03]` **torch-2.12 venvs need `uv pip install torchcodec`** — torchaudio 2.12
defaults to the TorchCodec backend for `.load`; without it, real audio I/O throws "TorchCodec
is required" — and it ONLY surfaces at actual conversion, NOT at import/model-load. Lesson:
validate real I/O, not just import, when provisioning ML engine envs. (seed-vc on torch 2.4
uses the legacy backend, exempt.)
- `[2026-06-03]` **Backgrounding `althing-cli monitor` with an inline shell `&` (instead of
the Bash-tool `run_in_background`) orphans it** — it survives the shell exit, holds the
per-handle flock UNTRACKED (won't notify the session), and `stop-monitor` doesn't detect it.
Fix: find + kill the orphan PID (verify cwd=this repo / handle first — nh3-dev is shared, other
agents' monitors run there too), then re-arm via run_in_background. Always re-arm tracked.
- `[2026-06-03]` **`uv pip install .` fails on SmoothKen/knn-svc** (and similar script-repos)
— it's analysis scripts + a poetry pyproject, no buildable package (setuptools
package-discovery error). Install the pyproject deps directly, don't build the "package".
- `[2026-06-02]` **Fish (fish-s2 / OpenAudio S1-mini) progressive streaming — SHELVED (sub-realtime).** Benched RTF on A6000: 0.72x (12w) / 0.82x (30w) / 0.86x (60w), **mean 0.80x = sub-realtime**, so client-side chunking would starve (same reason chatterbox-fast needs turbo's RTF>1). Root cause of the buffering (dvalin-smithy-dev deep research, verified in our code text2semantic/inference.py L600-607): Fish only chunks on `<|speaker:X|>` tags; **plain text -> batches=[whole text]** -> all semantic tokens generate before any audio (chunk_length inert). Plus a 2nd layer: kui/ASGI StreamResponse doesn't flush (header produced t=1s, delivered t=23s) -> fix = anti-buffering headers (X-Accel-Buffering:no / Transfer-Encoding:chunked) in tools/server/views.py (kept on file, not applied). A rebuild does NOT fix this (current main same logic). **STANDING REVISIT TRIGGER: when an RTX Blackwell Pro lands in the fleet -> bench fp4-quantized Fish; if RTF > ~1.5x, give it the chatterbox-fast treatment** (client-side adaptive buffer-ratchet chunker driving /v1/tts with small text pieces). Projection: fp4 (~1/4 weight bytes, memory-bound AR decode) + Blackwell (GDDR7 ~1.8TB/s vs A6000 0.77TB/s, native FP4 cores) ~ 2-3x RTF; validate fp4 voice quality (ear/ECAPA) before committing. For now Fish stays a buffered catalog entry (great for SAVED gens, not the live-audition lane).
- `[2026-08-03]` **ComfyUI `--enable-triton-backend` on the irv-ml1 A6000 crashes EVERY render — Ampere has no hardware e4m3.** adhoc-agent's operator-approved probe: comfy_kitchen's triton backend has a FUSED int8 matmul that would beat the eager backend's ~1.9x-slower unfused int8 path (21.3s vs 11.2s fp8 on the Moody Krea2 int8 checkpoints). Flipped it (added to `COMFY_CMDLINE_EXTRA`, recreated) → `triton.compiler.errors.CompilationError: ValueError("type fp8e4nv not supported in this architecture. supported: fp8e4b15, fp8e5")` in `comfy_kitchen/backends/triton/quantization.py:145 dequantize_per_tensor_fp8`, failing at **node 5 CLIPTextEncode**. Triton's fp8 dequant kernel targets `fp8e4nv` (Hopper/Ada e4m3); **sm_86 Ampere (A6000) lacks hardware e4m3** → the JIT compile dies. With triton on it grabs the **global** `--fp8_e4m3fn-text-enc` dequant, so every render (fp8 AND int8) dies upstream at the text-encode step — the int8 UNet path never ran, so the convrot-coverage caveat wasn't even the limiter. Reverted cleanly (~15s to healthy, image unchanged `sha256:94afb8ca`, sage intact, prod restored). **The parked cu130 rebuild won't fix it** (e4m3 = hardware format, not CUDA version). **DEFERRED to the Ada refresh** (operator: "ada is coming, we'll optimize then" — Ada sm_89 has native e4m3, so triton's fp8 path should compile there). **Mechanics:** `--enable-triton-backend` is a compose `environment:` var, so toggling it needs `docker compose up -d` (**recreate**), NOT `docker restart` (reuses the baked env, no-ops silently). Full: auto-memory `parked_triton_backend_ampere_fp8`.
- `[2026-06-02]` **Context-priming at chunk joins (chatterbox-fast §1.6) —
ABANDONED (discard-cut leaks the prefix).** To give a chunk backward prosodic
context, prepend the prior sentence, generate `prefix+content` together, then
discard the prefix audio. Built + opt-in shipped (commit d707439), live-A/B'd,
reverted (090e70a). The kill: `generate()` returns one finished waveform with
NO marker for where the prefix ends, and the model renders the same prefix with
different timing solo vs followed-by-content — so locating the cut (generate
prefix solo → measure duration → snap to nearest energy-min pause within ±0.4s)
is a guess that left a whole clause of prefix in the output ("...without a trace
of sarcasm," spoken twice; operator caught it). A reliable cut needs token-level
boundaries (= the abandoned native-streaming arc) or per-chunk ASR/forced-
alignment (heavy, imperfect, eats the latency budget). → Coherence loss at joins
stays an ACCEPTED limitation; cold adaptive-chunk streaming judged "really good".
Scheduler-side work that DID land + survive: affordability-gated priming math
(a 2nd pass can't starve the buffer) — sound, but moot without a working cut.
- `[2026-06-02]` **Native frame-level streaming on Chatterbox-TURBO — ABANDONED
(turbo isn't built for streaming).** Long R&D arc; record so it's not
re-derived. (1) The model's flow is CosyVoice2-derived but `S3GenStreamer` is
referenced-in-docstring-only (not implemented). (2) The lib's
`flow_inference(finalize=False)` is BUGGY: the lookahead trim removes
`pre_lookahead_len(3)*token_mel_ratio(2)=6` frames from `h` but NOT from
`h_masks`/conds → decoder shape mismatch (e.g. 656 vs 662). A 1-line patch
(`h_masks = h_masks[:, :, :-pre*ratio]` after the `h` trim) + sizing the
meanflow noise to the trimmed length makes finalize=False RUN. (3) BUT the
flow encoder uses FULL-context attention (`static_chunk_size=0`), so
incremental/cumulative decode is **prefix-unstable** — adding tokens
re-attends and shifts earlier mel (maxdiff ~0.30-0.39 vs one-shot,
irrespective of fixed-noise slicing or emit-margin). (4) Forcing
`static_chunk_size>0` on the 2 modules that carry the attr did NOT stabilize
it (decoding_chunk_size is a forward-arg, not settable via attribute). Verdict:
true sub-second frame-streaming on turbo needs deep model-attention surgery
with quality risk — not worth it. Matches research ("turbo+streaming
unsolved"; vLLM-turbo outputs noise; davidbrowne17 streaming fork is
BASE-only). → Use adaptive-chunking instead.

# Make vm.overcommit_memory=1 durable on ana-ml2 (GPU inference host).
#
# Why: ana-ml2 runs vm.overcommit_memory=0 (heuristic) with zero swap, so the
# CommitLimit is ~RAM/2 (~283 GB of 566 GB). The resident vLLM services already
# commit ~224 GB of address space, leaving < 60 GB of headroom. A large model-file
# mmap (e.g. the 50 GB NVFP4 shard during HF->native conversion, or a vLLM model
# load) then fails with ENOMEM despite ~393 GB of RAM actually being free — the
# kernel rejects the *commit*, not the allocation.
#
# overcommit_memory=1 (always overcommit) is the conventional setting for ML hosts
# that mmap large files: the real RAM is there to back the pages, and the heuristic
# accounting is the only thing in the way. Operator-directed permanent + durable
# (2026-06-17). A drop-in under /etc/sysctl.d/ applies at every boot.

# stop mog-sec (GPU1) -> move gen GPU0 -> GPU1 -> GPU0 empty for training
#
# Operator call 2026-08-24: rather than train beside `gen`, move `gen` off GPU0
# entirely and stand `sec` down for the night. Training then gets a whole card
# (95.60 GiB) instead of a shared one, and the fleet's general seat never goes
# dark beyond its own restart.
#
# ⚠⚠ ORDER IS LOAD-BEARING — DO NOT REORDER THE STEPS.
# `gen` runs at --gpu-memory-utilization 0.43, which vLLM reads as a fraction of
# TOTAL card memory: 0.43 x 97,887 MiB = 42,091 MiB that must be FREE at startup
# or the engine refuses to boot. GPU1 has only 19,446 MiB free while mog-sec is
# up. Recreating `gen` onto GPU1 first would take the fleet's main seat down and
# leave it down. mog-sec stops FIRST, and step 3 hard-gates on the freed memory
# before `gen` is touched at all.
#
# ⚠ `stop`, never `down`. `down` removes the container; `stop` leaves it in
# place so the close playbook can `start` it. Both seats are `restart:

# Set a host-wide docker nofile floor on corviduo-dev.
#
# WHY: Worldtree #401 — a slow fd accrual in worldtree-personal hit the 1024
# soft nofile ceiling and converted into a hard deadlock. Raising the floor
# turns any recurrence into observable degradation instead of a wedge.
# Operator authorized the raise 2026-08-17 (relayed via worldtree-dev,
# thread 01M08QQ655XD6VKEV7MA9GX0NS); sizing 65536 agreed with worldtree-dev.
#
# WHY THE DAEMON LAYER: /opt/worldtree-*/compose.yaml on this host is written
# by the team's CI `deploy` identity, so a host-side compose edit reverts on
# the next deploy. Daemon config is infra-ops-owned, survives every CI deploy,
# and covers all containers on the box — not just worldtree. worldtree-dev
# ALSO shipped an explicit compose-level pin (e41b139) as the belt to this
# braces; the two are deliberately redundant.
#
# ACTIVATION — READ THIS BEFORE ASSUMING THE FLOOR IS LIVE.
# `default-ulimits` is NOT in dockerd's SIGHUP-reloadable set. Measured on
# Docker 29.4.3 (corviduo-dev, 2026-08-17): after `systemctl reload docker` the
# daemon's own "Reloaded configuration" log line enumerates the live config and
# `default-ulimits` is ABSENT from it, and a freshly created container still
# reports `ulimit -n` = 1024. The reload step below is therefore harmless but
# insufficient on its own.
#
# So this playbook STAGES the floor; it does not activate it. Activation needs a
# full `systemctl restart docker`, which with live-restore unset BOUNCES EVERY
# CONTAINER on the host (13 of them here, including all three worldtree
# instances) — deliberately not taken here, because #401 is not urgent at fd
# ~100 and worldtree-dev's explicit compose-level pin (e41b139) already covers
# the worldtree services on their next recreate. Expect verify step 3 to FAIL
# until a dockerd restart or a host reboot happens.
#
# If you want it live without a bounce, add `"live-restore": true` to
# daemon.json FIRST (that one IS reloadable), then restart — containers survive
# the daemon going away. That is a separate change with its own blast radius;
# it was not in scope for #401.
#
# FOOT-GUN: an invalid daemon.json does not break a reload (dockerd logs and
# keeps the old config) but WILL break the next dockerd *start*. The playbook
# validates the JSON before reloading and refuses to proceed otherwise.

# Run: scripts/elway infra-ops@10.0.50.45 --playbook playbooks/esh-cutover-1-quiesce-docker-vm.yaml
#
# Why this is first and why it is not optional: /mnt/books and /mnt/backup are
# `hard` NFS from CT 103 on esh-pve-nas. A hard mount does not fail when the
# server goes away — it blocks forever in D-state, and the only known remedy is
# rebooting THIS host. /mnt/books was deliberately left hard because calibre's
# SQLite risks corruption under `soft`, so the mount option is not the fix; the
# quiesce is.
#
# Measured 2026-08-18: exactly one container binds these paths
# (calibre-web-automated -> /mnt/books/calibre/{ingest,calibre_library}) and
# /mnt/backup has no container consumers at all. The blast radius is one service,
# not the seventeen containers on this host.

# esh-pve-nas cutover, step 3 of 5 — point the ESP at the new /boot and reboot.
#
# Run: scripts/elway root@esh-pve-nas --playbook playbooks/esh-cutover-3-esh-pve-nas.yaml
#
# PRECONDITION: steps 1 and 2 must have run. Both NFS clients hold `hard` mounts
# from CT 103 which lives on this host; taking it down with them mounted wedges
# esh-docker-vm in unkillable D-state. A guard below refuses to proceed if either
# client is still mounted.
#
# ⚠ ORDERING TRAP, and it is the reason this is a playbook and not four commands:
# `zfs set mountpoint=/` on a dataset that is CURRENTLY MOUNTED makes ZFS unmount
# and REMOUNT it at the new location — i.e. it would try to mount the ZFS root
# over the live ext4 root of a running hypervisor. canmount=noauto does not save
# you; that governs automatic mounting at import, not an explicit property change
# on a mounted dataset. The dataset must be UNMOUNTED first, which means the
# chroot binds have to come down first, which means grub-install and grub-reboot
# have to happen BEFORE any of that. Hence the sequence below is not negotiable.
#
# This playbook ENDS BY REBOOTING THE HOST. elway will lose the connection; that
# is expected, not a failure.

changed_when: "false"
# This host has no ssh keys to the NFS clients, so the caller verifies their
# mount tables and attests via --var quiesced=yes.
#
# ⚠ THE RUNBOOK'S BLAST RADIUS WAS WRONG. It named two dependents. `ss` on CT 103
# showed FIVE distinct clients on 2026-08-18:
# 10.0.50.45 esh-docker-vm hard -> quiesced by step 1
# 10.0.250.35 esh-pve hard -> quiesced by step 2
# 10.0.50.60 esh-vm-db hard -> DELIBERATELY LEFT MOUNTED (see below)
# 10.0.50.154 vm-esh-nas n/a -> is VM 104 on THIS host; dies with it
# 10.100.10.50 nh3-dev soft,ro -> errors instead of blocking; safe
#
# esh-vm-db is left mounted on purpose. It is a backup TARGET with no live user:
# resticprofile-backup and postgresql-dump next fire ~19h out, and a hard mount
# with nothing actively using it blocks and then resumes when the server returns
# — that is what `hard` is for. Unmounting it would mean an unmount/remount cycle
# over the qemu guest agent on a host with no ssh access, where a failed remount
# breaks backups silently. Leaving it is the lower-risk branch, not the lazy one.
# The gate is `quiesced`, which the CALLER sets only after checking each client's
# mount table directly (this host has no ssh to them; see step 1/2 playbooks).
#
# ⚠ It deliberately does NOT gate on server-side NFS session count. Measured
# 2026-08-18: esh-docker-vm's sessions drained within ~90s, but esh-pve held 11
# established connections to :2049 indefinitely with NO mounts in either
# `findmnt` or `/proc/mounts` and nothing holding a cwd there. That is the Linux
# NFSv4 client keeping its transport alive past the last unmount, and it is the
# wrong thing to gate on: the failure this whole runbook exists to prevent is a
# process blocking on a MOUNTED hard filesystem when the server vanishes. With no
# mount there is nothing to block on — an idle socket to a departing server just
# resets. Gating on sessions would have stalled the window forever on a condition
# that never clears and never mattered.

# esh-pve — move from the software watchdog to the PCH hardware watchdog.
#
# WHY: esh-pve hard-froze at 03:34 on 2026-08-19 (no panic, no OOM, no MCE —
# the journal simply stops mid-line) and stayed frozen for ~4.5 hours until it
# was power-cycled by hand. Everything on it went with it, including the only
# DNS resolver the esh-userland VLAN is handed, so the whole house lost name
# resolution.
#
# Nothing on the box could have recovered it:
# - `softdog` was the loaded watchdog. A SOFTWARE watchdog cannot rescue a
# hard kernel freeze, because the frozen kernel is the thing that would
# have to fire its timer.
# - Proxmox's `watchdog-mux` held /dev/watchdog but never armed it: it only
# pets the device while an HA client is connected, and this cluster has no
# HA resources configured (`ha-manager status` reports quorum only).
#
# The board's PCH TCO timer is present and NOT blocked by firmware — verified
# before writing this:
# iTCO_wdt: Found a Intel PCH TCO device (Version=6, TCOBASE=0x0400)
# iTCO_wdt: initialized. heartbeat=30 sec (nowayout=0)
# (no "unable to reset NO_REBOOT flag" line, which is the BIOS-blocked case).
#
# APPROACH: systemd owns the hardware watchdog directly. Setting
# WATCHDOG_MODULE=iTCO_wdt in /etc/default/pve-ha-manager would point
# watchdog-mux at the right device but would still never arm it without HA, so
# it does not solve this. systemd's RuntimeWatchdogSec pets unconditionally,
# which is what "reboot me if I wedge" actually requires.
#
# ⚠️ CONSEQUENCE — READ BEFORE ENABLING PROXMOX HA ON THIS CLUSTER.
# This masks `watchdog-mux`. If HA is ever configured on esh-pve, watchdog-mux
# must own /dev/watchdog again and this must be reverted, or HA fencing will
# not work. That is not a near-term concern: esh-pve-cluster is TWO nodes with
# no qdevice, so a single node loss already costs quorum and the survivor would
# fence itself. HA here would make availability worse, not better.
#
# Revert: unmask + enable watchdog-mux, delete the three dropped files,
# `systemctl daemon-reexec`, reboot.

# esh-pve-nas — make the boot default track new kernels instead of pinning one.
#
# Run: scripts/elway root@esh-pve-nas --playbook playbooks/esh-pve-nas-fix-grub-default.yaml
#
# ⚠ MUST RUN BEFORE THE 225-PACKAGE UPGRADE. No reboot required.
#
# THE DEFECT (introduced by the 2026-08-18 cutover, found before it bit):
# the cutover left `saved_entry=pve-zfs-root`, a hand-authored 40_custom entry
# that HARDCODES `/vmlinuz-6.8.12-13-pve`. The pending upgrade installs
# proxmox-kernel-6.8.12-42. That gives two failure modes, both bad:
#
# 1. If -13 is autoremoved, the default entry points at a kernel that does not
# exist -> unbootable -> console recovery, on a host with NO IPMI/BMC/serial.
# 2. If -13 survives, the host silently keeps booting the OLD kernel forever.
# You install 161 security updates including a kernel and never run it,
# which defeats most of the reason for patching.
#
# That entry was written for a one-time cutover target and was never fit to be
# the standing default across kernel upgrades.
#
# THE FIX: stop hand-authoring the ZFS entry at all.
# - GRUB_DEFAULT=0 -> boot the first auto-generated entry, which grub-mkconfig
# regenerates for the newest kernel on every install.
# - Those auto entries already boot ZFS correctly: /etc/default/grub.d/zfs-root.cfg
# appends the pool-qualified root=ZFS=nvme/ROOT/pve-1 that grub-mkconfig cannot
# derive itself (GRUB's ZFS reader cannot open a pool with encryption/
# large_dnode/zstd_compress, so its fs_label probe returns empty).
# - Drop the redundant pve-zfs-root entry.
#
# The ROLLBACK entry stays PINNED, and that is correct, not an oversight: it boots
# the untouched ext4 root on the DOM, whose /boot is never regenerated by anything
# — update-initramfs writes only to the /boot LV. Its kernel genuinely never
# changes, so hardcoding it is the accurate description of that filesystem.

# esh-pve-nas — PHASE 2 of the ZFS-root migration: build the boot artifacts.
#
# Runbook: docs/runbooks/esh-pve-nas-boot-migration.md
# Run AFTER playbooks/esh-pve-nas-stage-zfs-root.yaml.
#
# ⚠ THIS PLAYBOOK DELIBERATELY DOES NOT RUN `grub-install`.
#
# That is the whole safety design. Everything expensive and error-prone — the
# ZFS-capable initramfs, the generated grub.cfg, the rollback menu entry, the
# grubenv default — is built and verified here, onto the NEW /boot LV, while the
# ESP stub on the DOM still points at the OLD /boot inside the ext4 root LV.
#
# So until cutover the host's boot path is byte-for-byte what it has been for
# 140 days. An unplanned reboot mid-staging lands exactly where it always did.
# The cutover reduces to one idempotent two-second command plus the reboot:
#
# chroot /mnt/newroot grub-install --target=x86_64-efi \
# --efi-directory=/boot/efi --bootloader-id=proxmox
# chroot /mnt/newroot grub-reboot '<zfs entry id printed by verify below>'
# reboot
#
# Why the rollback entry matters here: the ext4 root LV keeps its own /boot
# contents (the new LV is a copy, not a move), and its initrd is never
# regenerated — update-initramfs inside the chroot writes only to the new LV.
# So the rollback path is genuinely independent of anything we build.
#
# Why GRUB_DEFAULT=saved: the default stays pinned to the ext4 rollback entry.
# At cutover `grub-reboot` marks the ZFS entry to be tried EXACTLY ONCE. If the
# ZFS root fails to come up, the next reboot returns to ext4 with nobody at the
# console — which matters because a failed boot here takes CT 103 `esh-nas`
# down and wedges esh-docker-vm into unkillable D-state on hard NFS.

# esh-pve-nas — STAGE the PVE root migration off the USB DOM onto ZFS.
#
# Runbook: docs/runbooks/esh-pve-nas-boot-migration.md
# Design: boot chain stays ext4 on the DOM; root moves to nvme/ROOT/pve-1.
#
# THIS PLAYBOOK DOES NOT CUT OVER. It leaves the host still running from the
# ext4 root on the DOM. Nothing here changes what the next reboot does — the
# bootloader phase is deliberately a separate playbook.
#
# What it does, all live, no downtime:
# 1. Reclaims 512 MB from the 768 MB swap LV for a dedicated /boot LV
# (operator's call 2026-08-17: shrink swap to 256 MB rather than drop it).
# 2. Populates that LV from the current /boot.
# 3. rsyncs the live ext4 root into the ZFS dataset nvme/ROOT/pve-1.
# 4. Writes the ZFS copy's /etc/fstab for the post-cutover layout.
#
# The ext4 root LV is never modified — it stays byte-intact as the rollback,
# including its own /boot contents, which the new mount only shadows.
#
# Preconditions (verified 2026-08-17, re-asserted as guard steps below):
# - nvme/ROOT/pve-1 exists, canmount=noauto, encryption off
# - /etc/zfs/zpool.cache populated with ALL THREE pools (nvme, ssd, tank).
# ⚠ A cache holding only `nvme` flips the host from import-by-scan to
# import-by-cache and leaves ssd+tank unimported at boot — which breaks
# CT 103 `esh-nas`, whose 12 bind mounts span all three pools.
#
# Rerunnable: every step is guarded, so a second run reports ok/skipped.

# Upgrade a Proxmox node's packages. DOES NOT REBOOT — reboot is a separate,
# deliberate step because it has cluster and NFS consequences this playbook
# cannot see.
#
# Run: scripts/elway root@<node> --playbook playbooks/pve-node-upgrade.yaml
#
# ⚠ Both ESH nodes are members of the 2-node `esh-pve-cluster` (quorum 2, no
# qdevice). Upgrading is safe while both are up; REBOOTING makes the survivor's
# /etc/pve read-only until the node returns. Do one node at a time and let the
# cluster go quorate again before touching the second. corosync 3.1.9 -> 3.1.10
# is a minor bump and rolling-safe, but do not leave the pair skewed longer than
# the window needs.
#
# ⚠ For esh-pve-nas specifically, run playbooks/esh-pve-nas-fix-grub-default.yaml
# FIRST. Its boot default used to pin a single kernel, so installing a new one
# would either break the default entry or silently keep booting the old kernel.
#
# ⚠ The corosync bump RESTARTS corosync mid-upgrade, which on a 2-node cluster is
# a brief quorum event — both nodes' /etc/pve go read-only for a few seconds and
# then recover. Guests are unaffected and PVE does this routinely, but do not run
# it concurrently with anything that writes cluster config, and check
# `pvecm status` afterwards rather than assuming.
#
# Conffile policy: --force-confdef + --force-confold, i.e. keep the on-disk
# version wherever a package ships a changed conffile. That is the right default
# for these hosts (hand-tuned /etc/default/grub, grub.d drop-ins, storage.cfg),
# and it means a genuinely important upstream conffile change will be left as a
# .dpkg-dist file rather than applied — the verify phase lists any that appear so
# they are not silently ignored.

# Re-pin a Worldtree instance's WORLDTREE_IMAGE to the SHA it is actually
# running, closing the stale-`:latest` recreate hazard.
#
# THE HAZARD (found 2026-08-22, Worldtree #410): both corviduo-dev instances
# had `WORLDTREE_IMAGE=…/worldtree:latest` in their .env while running
# SHA-tagged images from that day. The local `:latest` tag pointed at
# b19afd71d7cc, built 2026-06-14 — 69 days stale. So ANY `docker compose up`
# on either instance, by anyone, for any reason, silently DOWNGRADED that
# service by 69 days. This is the same footgun that caused the 2026-06-15
# outage; the pin is what disarms it.
#
# This is a stopgap. The durable fix is worldtree-dev's deploy workflow
# stamping the deployed SHA into .env at each deploy (queued repo-side).
# Until that lands, re-run this after any deploy that moves the image.
#
# Usage — one run per instance:
# scripts/elway corviduo-dev --playbook playbooks/repin-worldtree-image.yaml \
# --var instance_dir=/opt/worldtree \
# --var api_container=worldtree-worldtree-api-1 \
# --var expect_sha=ae88a057c0ed
#
# The edit is INERT until the next recreate — it changes what the NEXT
# `compose up` resolves to, not the running container. That is the intent:
# make the next recreate safe rather than dangerous.
#
# ⚠ THE `worldtree-pinned` INSTANCE NEEDS AN EXTRA STEP FIRST. It runs image
# sha256:446e5807… which has NO repo tags at all — it is dangling, kept alive
# only by the running container referencing it. So there is no tag to pin to,
# and this playbook's guard will (correctly) refuse. Tag it before re-pinning:
#
# docker tag sha256:446e5807bf43639be7d285864a7716816880e0f5c0892427e72800f4aa8ffc56 \
# gitea.phasefinal.com/vh/worldtree:446e5807bf43

# only by a container is one `docker rm` away from being garbage-collected,
# and this one is the frozen reference the whole instance exists to provide.

# Tighten a world-readable compose `.env` that holds secrets to 0600.
#
# WHY: found 2026-08-23 on ana-docker. Eight stacks kept secret-bearing .env
# files at mode 0644 — readable by every local account on the box (verified by
# reading one as `nobody`; the host has four interactive users). Six other
# stacks already used 0600, so this is converging on the existing house
# pattern rather than inventing one.
#
# Usage — one run per stack:
# scripts/elway ana-docker --playbook playbooks/tighten-env-perms.yaml \
# --var stack=vaultwarden
#
# SAFE BECAUSE, verified before writing this:
# - every target .env is owned by lkraven, and lkraven is the deploy user,
# so 0600 preserves the deploy path
# - none of them is bind-mounted INTO a container. They are consumed either
# by `env_file:` or by `${VAR}` interpolation, both of which docker
# compose reads at deploy time as the invoking user. A .env that WERE
# bind-mounted would be read by the container's own UID and 0600 could
# break it — check for that before adding a stack to this sweep.
# - chmod does not touch a running container; env is injected at create.
#
# The playbook re-checks ownership itself and refuses if it is not lkraven,
# so a stack that does not fit the above cannot be swept in by accident.

"""dns-sync.py — reconcile the fleet's AdGuard resolvers against dns/internal.yaml.
Source of truth is the file; the resolvers are derived state. Same posture as
deploy-stack.sh: show a diff, ask, then apply.

scripts/dns-sync.py --dry-run # diff only, never write
scripts/dns-sync.py --yes # skip the prompt

AUTHORITY IS SCOPED TO THE ZONE, NOT THE RESOLVER. Only rewrites ending in
`.internal` are considered. The ESH resolver carries hand-made `esteban.net`
entries that predate this system; they are read, ignored, and left alone. If
this ever grows to manage other zones, that scoping is the thing to be careful
with — a resolver-wide authority would silently delete a colleague's work.
CREDENTIAL: pulled from the vault, never hardcoded.
secret get nh3-dev/adguard-infra-ops-password
The vault appends a trailing newline on read; it is stripped here, because a
password with a stray \\n fails auth in a way that looks like a wrong password.

# Training throughput probes
Instruments for finding where a training step's time actually went. Written
2026-08-24 during the Gemma-4 26B-A4B ERP/RP tune investigation; the lessons
they produced live in
[`docs/pfi/training-throughput-playbook.md`](../../docs/pfi/training-throughput-playbook.md).
**These are diagnostic instruments, not production code.** They hard-code paths
for that run. Adapt the constants at the top; keep the measurement design.
## The probes
| script | settles | GPU | runtime |
|---|---|---|---|
| `step0_mask.py` | mask band structure; which layers keep the `is_causal` fast path | no | ~30 s |
| `step2_padding.py` | padding waste, length distribution, CE chunk sizing | no | ~2 min |
| `step_bucket.py` | bucketing gain, bucket-size sweep, source diversity | no | ~3 min |
| `step1_profile.py` | scaling fit, padding penalty, CE wall clock, kernel table | **yes** | ~15 min |
Run in that order. Only the last needs the real checkpoint, and it wants an
idle card — it loads ~48 GiB and peaks near 77 GiB at `2 × 16,384`.
## Design rules worth preserving when you adapt these
**`step1_profile.py` reuses the harness's own `discover_target_modules` and
replicates its `compute_loss` byte-for-byte** rather than re-implementing the
step. A probe that reimplements the training step measures the probe. If you
port this, keep the import from the real harness.
**`step0_mask.py` needs no weights and no GPU** — SDPA backend selection and
mask construction depend on shapes, dtype and mask presence, not on weight
values. That is what makes the correctness assertion cheap enough to run before
every job.
**The scaling test takes three points, not two.** Two points over three
plausible terms (quadratic, linear, fixed-per-batch) is underdetermined; see
playbook §1.1 for the hour that cost.
**`step_bucket.py` sweeps bucket size deliberately.** The first version
re-sorted within each bucket, which silently collapsed every bucket size to a
full global sort and made the sweep a no-op. If you change the pairing logic,
check that the sweep still varies something.
## Raw evidence
`step1-profile-output-2026-08-24.txt` is the unedited output of the run the
playbook's numbers come from — scaling points, padding penalty, CE timing, and
the full `key_averages()` kernel table. Kept so the claims can be re-derived
rather than taken on faith.
⚠ That table **double-counts**: `key_averages()` lists both the ATen op and the
CUDA kernel it launched, each carrying the same self device time. Sum device
kernel rows only. See playbook §3.4.

"""Steps 1/2/4 - profiler kernel table, sequence scaling, isolated CE timing.
Loads the real model exactly as erp_sft_harness.runtime does (same
from_pretrained args, same PEFT config, same gradient checkpointing, same
chunked-CE compute_loss) and measures:
A. sequence scaling 2x2048 / 2x8192 / 2x16384 fwd+bwd
linear-dominated -> time falls ~8x from 16384 to 2048
launch-bound -> time barely falls
quadratic-dominated -> time falls ~64x
B. isolated CE wall clock (CUDA events around the chunked-CE block)
C. torch.profiler kernel table, sorted by self CUDA time
D. expert-GEMM launch counts (settles grouped_mm without kernel-name
archaeology: 128 sequential launches per layer = no-op, 1 = grouped)
Runs on GPU0, which is reserved and idle. Nothing else touches it.

"""Measure bucket-to-pair / shuffle-to-mix against the REAL encode cache.
Brokkr's design, validated on measured record lengths rather than a calibrated
length model:
1. sort records by length
2. cut into buckets of BUCKET records
3. form micro-batches of 2 WITHIN each bucket (adjacent after sort)
4. shuffle the resulting MICRO-BATCHES globally, seeded
Padding efficiency is a property of the pairing only, so step 4 costs nothing
and restores root-mixing inside each accumulation window.
Also applies the fitted cost model from the replica scaling test to convert
token savings into predicted wall clock.
