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 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 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 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.

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.

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 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.
2026-08-23 22:31:13 -07:00
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 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.

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 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.

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.

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.

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.

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 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.

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 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.

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.

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

                        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

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.

  PPL                                                still blocked

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.

vh ba53c30192 feat(gen-seat): cut over to orcarouter — live, 7/7 aliases, vision intact, no think-leak
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.
2026-08-21 01:47:28 -07:00
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 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.

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 78484ac87d memory: GPU0 seat boot order is part of the state — restore rule + KV-pool baselines
vLLM sizes --gpu-memory-utilization against total VRAM but gates startup on free
VRAM, so the GPU0 pair coexists only in its original boot order. Records the
restore sequence (meromero to healthy first, then gen), the observed-not-slept
rule, and the KV-pool baselines to verify a restore against — nvidia-smi used-MiB
is the wrong check, it swings ~7 GB on allocator slack at identical capacity.

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 8c354a0e79 memory: snapshot — Cold-Fusion thesis PROVEN (MTP 59.1% > incumbent 47%)
Flip the Cold-Fusion in-flight line to thesis-proven: L35 quantized to mixed
NVFP4, MTP acceptance 59.1% median beats the incumbent Heretic graft's ~47%,
abliteration survives quant. Not cut over — cutover is a separate operator
decision. Records the two env foot-guns hardened (quant venv config-delegation
drift; single-file no-index quant needs a header-built index).
