Recent decisions (archived)

• [2026-08-26] Run 3's corpus is built and HELD — creative-writing-multiturn is a MEGAMIX containing bluemoon, PIPPA, LimaRP and stheno, and the remix promoted two roots that overlap at median jaccard 0.873. Dedup direction reversed to keep the primary source. F1 does not do what the recipe says; F2 does. → persistent-memory.d/2026-08-26-run3-corpus-and-the-megamix-containment.md Archived 2026-09-10.

• [2026-08-26] No conversation admission threshold for run 3 (brokkr delegated, then endorsed). Masked context costs the transformer body but NOT the LM head — the harness drops IGNORE_INDEX before the 262k-vocab head — so a 20% trim buys ~35 min against a 3-hour run, and it would be a fifth filter confounding a run whose purpose is testing the filters alone. Tracked in the run-3 detail file. Archived 2026-09-10.

• [2026-08-26] Run 2's gate FAILED and is recorded as a FAIL — T3 constraint −12.0 against a ~1 pt floor. But gate 1 is the result: T6 spatial +15.0 where run 1 failed the same axis at −3.5, base swap the only intended variable. Neither run ships; the pair prices what the abliteration cost. Plus the long-form-only stability regression a short-answer gate would have passed, and PIPPA's 123-word clip in the length signal. → persistent-memory.d/2026-08-26-erp-run2-complete-and-served.md Archived 2026-09-10.

• [2026-08-26] Run 2 complete, merged, coherence-gated and serving as erp-tune-v2 — stock-instruct base, and the mask proven by a −221,712 loss-token delta against byte-identical context. Also the p50 claim I asserted and had to withdraw. → persistent-memory.d/2026-08-26-erp-run2-complete-and-served.md Archived 2026-09-10.

• [2026-08-26] Playbook §4 written: "when the artifact lies about itself" — seven landmines plus a pre-launch checklist, from a night in which three separate fixes each shipped a check that could not fail. The unifying line is brokkr's: when you change what an artifact means, every derived artifact keyed on the old meaning is now a liar. Commits dae6ede → d54f256; the doc is docs/pfi/training-throughput-playbook.md (filename kept for inbound links; scope is now wider than the name). Archived 2026-09-10.

• [2026-08-26] Served under a NEW name on a NEW port (erp-tune-v2 / :8098), never re-pointing erp-tune-v1. Run 1's artifact still exists and is still what that name refers to; re-pointing would be the silent substitution the standing no-false-aliases rule forbids. brokkr independently asked for the same and additionally wants the concrete backing model + date in provenance, not just the alias — an alias has silently changed meaning under recorded results before. Archived 2026-09-10.

• [2026-08-26] DPO stage gated on an axis-list decision that is not mine to make — docs/pfi/erp-dpo-stage-prep.md. No preference data for refusal axes exists; trl is not installed; the Gutenberg sets on disk are prose-quality only. ⚠ Do not install trl (or anything) into the training venv while a run is saving — a resolution that upgrades transformers under a live process can break its save path. Archived 2026-09-10.

• [2026-08-16] Abliterated models go CATATONIC at the hard refusal edge — silence, not a decline. Abliteration removes the refusal direction, so at the genuine hard edge the model neither refuses nor complies → empty/degenerate output. 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. Archived 2026-09-02.

• [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. Archived 2026-09-02.

• [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). Archived 2026-09-02.

• [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. Archived 2026-09-02.

• [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. Archived 2026-09-02.

• [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. Archived 2026-09-02.

• [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. Archived 2026-09-02.

• [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. Archived 2026-09-02.

• [2026-08-25] The ERP/RP tune COMPLETED in 7.36h and passed its gate on the axis it was built for — diversity 22x its noise floor, attractor −11.3pt, zero memorisation on both arms. Also the noise-floor near-miss: brokkr was one step from reporting a 13-point T6 regression sitting inside twice his instrument's own variance.

ERP/RP tune run-01 COMPLETE — 7.36h, gate passed on the axis it was built for

[2026-08-25]

The run

1312/1312 in 7:21:52   train_loss 2.793   epoch 1.0
20.1 s/it FLAT across every 100-step window   (round 1: 35-46.5 s/it)
adapter: /tank/erp-tune/run-01/adapter/  410 tensors, provenance.json

47% faster than the round-1 projection of 13.85h, from two changes: the bucketed sampler and flex attention. Rate was flat — 19.7 / 19.8 / 20.4 / 20.3 across the four 100-step windows — which means the 35-46.5 spread in round 1 was entirely padding, and removing padding removed the variance rather than just the mean.

⚠ I quoted three different ETAs (6.9h, 8h, 7.3h) before I started using a rolling average. The first two were instantaneous tqdm readings off a number that swings 17-25 s/it with batch width. Only the rolling rate was honest. Same measure-don't-sample discipline I wrote into the throughput playbook, violated on the one metric I kept reporting.

lora_B gate — PASSED, twice

checkpoint-100   205/205 non-zero, median norm 0.829
final adapter    205/205 non-zero, median norm 1.708
vision_tower tensors: 0 on both

Median norm rising 0.829 -> 1.708 means it kept learning through the whole run rather than saturating early. This check never ran in round 1 (died at step 19, first checkpoint was 100) and it is the only failure mode that stays invisible until the acceptance gate reports base-identical numbers.

The gate — brokkr-smithy-dev

It did the thing it was built to do:

metric                    base A/B        tuned      delta      floor
attractor hit rate    94.8% / 96.8%       84.5%     -11.3pt     2.0pt
diversity (pairwise)  0.213 / 0.221      0.3948     +0.178     0.008

Diversity moved 22x its own noise floor. Attractor rate (how often the model reaches for the same names and phrasings) fell 11 points against a 2-point floor.

T1 100 · T2 95 · T3 96-97 · T4 98 · T5 100 · T6 81-82 · core ~94.2
memorisation: 0.0000 on BOTH arms, all three corpora

Zero memorisation closes the R20 licensed-prose exposure on measurement rather than argument.

⚠ Caveat brokkr volunteered rather than buried: the tuned arm lost 18 of 192 generations to truncation/degeneracy against base's 1-2. Lopsided exclusions plausibly flatter the diversity magnitude. Direction is unambiguous at 22x floor; the number carries an asterisk.

The noise-floor near-miss — the methodology lesson

brokkr was one step from reporting a 13-point T6 regression that sat inside twice his instrument's own variance.

--per-type 32     max swing across tasks:  9 points
--per-type 128    max swing across tasks:  1 point

His gate criterion is "no task regresses by more than one item" = 3.1 points at n=32. The instrument's own run-to-run noise was 3 items. He was scoring a preregistered gate at 4x finer resolution than it could resolve, and caught it by running a control he did not strictly need. Quadrupling n collapsed the noise exactly as binomial statistics predicts.

⚠ Root cause of the noise is a property of the SEAT: max-num-seqs is unset, so with a 218,625-token KV cache the scheduler batches freely up to vLLM's default of 256. Continuous batching changes reduction order and borderline items flip. Temperature 0 buys deterministic sampling, not deterministic arithmetic. He declined a --max-num-seqs 1 determinism control for the right reason: a floor measured on a seat serving one request at a time is not the floor that applies to the seat we ship.

The confound I built and he caught

I optimised a pipeline for production and then handed him its output as an eval instrument without asking whether those were the same job. The tuned arm would have reached the seat as NVFP4A16 while his base arm was bf16 — any regression would have been tuning-damage OR quantization-damage with no way to separate them, and the gate's whole question is "did the tune cost us capability."

Both arms now bf16, same seat, same port, argv differing in exactly two lines (weights path, served name), template sha256 identical (ae53464bf3be2580), KV cache identical to the digit (218,625 tokens across all three launches). Quantization moved downstream of the gate.

• [2026-08-25] 8.6% MFU was an accounting artifact — real utilisation 17-20%, and the cost was attention on AMPERE kernels. Two independent methods agreed to 2.6 points. Fixed by bucketing (padding 29.9%

The 8.6% MFU was an accounting artifact — attention on Ampere kernels

[2026-08-25]

The answer

Real utilisation was 17-20%, inside the honest stock band. The 8.6% divided the intended (windowed) FLOPs by the wall time the dense reality took.

nominal billed      27.1 TFLOPS x 34.85 s        =  9.4e14 FLOP
dense-sliding extra 25 layers, 2 seqs, 4 passes  = +8.2e14
padded full layers  lose the causal skip         = +3.5e14
work performed                                   ~  1.8e15  = 51-61 TFLOPS

The card was doing ~2x the arithmetic the architecture specifies, and the excess was the sliding window being computed and thrown away.

Two independent methods agreed

scaling fit (3 points, 2 params, residuals <3ms over 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

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%

67.8% vs 65.2% — 2.6 points apart, no shared assumptions. The two-term fit needed no constant term, which refutes launch-bound outright (3,840 expert-GEMM launches per forward are not the cost).

The mechanism, source-verified by brokkr's panel (arm: Bil)

masking_utils.py:292-301  _ignore_causal_mask_sdpa requires
                          kv_length < local_attention_size. 16384 >= 1024,
                          so THE SLIDING MASK ALWAYS MATERIALISES.
sdp_utils_cpp.h:259-267   flash rejects ANY explicit mask
sdp_utils.cpp:647         cuDNN head_dim capped at 128 -> unreachable
Context.h:480-485         prefer-cuDNN needs major 9 or 10; sm_120 is 12

⚠ The kernels are sm80 — Ampere-generation CUTLASS on a Blackwell card, with the forward on gmem, the memory-efficient backend's slowest fallback tier.

What actually fixed it

Bucketing (bucket-to-pair, shuffle-to-mix) — 29.9% padding -> 0.0%, and 78.3% of micro-batches become exactly zero-pad, which puts the 5 global layers back on is_causal. Measured: padding costs 9.4% MORE time for 24% LESS work at fixed width, because an explicit mask knocks those layers off the fast path.

⚠ Bucket size is NOT a diversity knob. Swept across a 256x range, roots per accumulation window stayed flat at 3.54-3.61. The global micro-batch shuffle does all the mixing; the bucket only costs padding. Use the tightest bucket.

flex_attention — Triton-generated so it compiles for sm_120 instead of shipping sm_80 binaries. 21.7x on sliding layers, 2.1x on global. Needs mandatory kernel_options at 32x32 blocks: 64x32 needs 102,400 bytes against a 101,376-byte hardware ceiling — misses by 1 KB, and Triton is already opting into the full 99 KB, so it is the card, not a default.

⚠⚠ The trap that produced TWO wrong published conclusions

torch._dynamo defaults to a recompile ceiling of 8. Every distinct sequence width is a new shape. On hitting the ceiling dynamo does not error — it silently falls back to UNCOMPILED flex, which is ~20x slower AND documented to "not work with the backwards pass and may produce incorrect results."

That artifact produced a bogus 0.76x slowdown and a bogus 2.9% loss divergence, and I believed and reported both. Raising the limit to 256 flipped the speed result to 1.41x.

The loss divergence turned out to be real but benign — adjudicated against fp32 MATH ground truth, both backends sit ~2e-3 from truth with flex fractionally CLOSER at every width. Do not re-open it by comparing the two backends to each other; that cannot answer it. Compare to fp32.

Process lesson

brokkr's panel produced four self-retractions in ninety minutes. Every retraction was a derivation; every survivor was a measurement. And the whole head_dim-512 SDP problem was already documented in zerofata's published Axolotl config since April — the right first stop for "why is this architecture slow" is practitioner configs for that exact base, before any panel.

• [2026-08-25] NVFP4A16 serving pipeline built and validated; MERGED WEIGHTS ARE MANDATORY. vLLM cannot serve a LoRA on ANY Gemma-4 — get_expert_mapping is unimplemented and the check branches on MoE-ness, not quantization. Plus the landmine: a targets=["Linear"] recipe misses all 11,520 expert tensors silently.

NVFP4A16 serving pipeline — built, validated, and the MoE landmine it found

[2026-08-25]

Pipeline at scripts/erp-tune-serve/ (commits 6a85829, ab980e9). Validated end-to-end against checkpoint-100 before the real adapter existed.

⚠⚠ THE LANDMINE: a targets=["Linear"] recipe misses EVERY MoE expert

before linearize_moe:  427 Linears,    205 targeted, experts 0
after  linearize_moe:  11,947 Linears, 11,725 targeted, experts 11,520
                       (30 layers x 128 experts x 3 projections)

Gemma-4 stores each layer's 128 experts as two fused 3-D nn.Parameter tensors (gate_up_proj [128,1408,2816], down_proj [128,2816,704]) — note the absent .weight suffix. A Linear-targeting recipe resolves 205 of 427 modules and zero experts, leaving 22.84 B params (88.5% of the model) in BF16 with no warning.

This is the same defect that killed QLoRA here via bitsandbytes. The blind spot is in the checkpoint layout, not the tool. Fix: llmcompressor.modeling.moe.linearize.linearize_moe — no registration needed, Gemma-4 satisfies FusedExpertsProtocol structurally. Playbook §3.15.

Scheme: NVFP4A16, deviating from the playbook default, on measured grounds

brokkr benched the W4A4 quant of this checkpoint at 12% on contradiction detection with CoT off against gen's 81% — the signature of 4-bit input activations on a reasoning-dense task. Plus W4A4 KLD is 2-4x worse past ~10k ctx on sm_120. This is a 16,384-ctx RP seat. Marlin's prefill cost accepted.

⚠ Several HF repos named …-NVFP4A16 declare input_activations num_bits 4 — W4A4 wearing an A16 label. The script refuses if the emitted config says 4.

Four silent defects the dry run found

1. transformers 5.15 MIGRATES the config schema on save — drops global_head_dim/num_global_key_value_heads, writes per_layer_config. transformers 5.10 (the llmcompressor venv) then reads num_key_value_heads as None and dies with TypeError: unsupported operand type(s) for //. Every working artifact on the box uses the OLD schema. Merge now downgrades it.
2. llmcompressor cannot auto-init a processor for a multimodal checkpoint — pass the tokenizer explicitly as processor.
3. save_pretrained does not carry processor_config.json — vLLM then fails with "Can't load feature extractor", which reads as a vision bug.
4. The quant needs more than GPU1's free 32 GiB. quant_with_gen_down.sh stops vllm-gen and restores it from a trap on EVERY exit path, using docker start not compose up so the container returns with its exact config.

Verified on the emitted artifact

served: Marlin NVFP4 kernel + Marlin MoE backend, coherent generation

⚠ The reference nvfp4a16 artifact triggers a vLLM warning that q/k/v carry different weight global scales ("likely reduced accuracy"). Ours does not — llmcompressor 0.12 links weight observers across fused groups automatically. The in-house quant is better than the downloaded one on that axis.

⚠ MERGED WEIGHTS ARE MANDATORY — and not for the reason we assumed

The open question was whether LoRA-on-NVFP4 hot-swap still silently no-ops. Retested on vllm/vllm-openai:latest: it refuses to start.

AttributeError: To support LoRA for MoE model,
                'get_expert_mapping' must be implemented

The check is in vllm/lora/utils.py::process_packed_modules_mapping and branches on is_moe_model() — quantization is not in the condition. gemma4.py, gemma4_mm.py, gemma4_mtp.py, gemma4_unified.py all have ZERO occurrences; deepseek_v2, mixtral, glm4_moe, ernie45_moe implement it.

vLLM cannot serve a LoRA on ANY Gemma-4, bf16 or quantized. Merging is the only path for this architecture, and it would have bitten identically on the unquantized base. A loud refusal is strictly better than the 0.24.0 silent no-op, which shipped a base model wearing the tune's name.

⚠ Base-viability pre-flight is now playbook §3.11 — three greps before picking a base. Grep the CLASS, not the file: mistral.py greps as SupportsLoRA=0 and is fully LoRA-capable via inheritance from LlamaForCausalLM. Archived 2026-09-09.

• [2026-08-25] **Refusal retention measured (base 0/100

Refusal retention — the axis the gate did not have, and the axis I measured wrong

[2026-08-25]

Why it exists

brokkr's gate measures reasoning (T1-T6), craft (diversity/attractor) and regurgitation (memorisation). Nothing measured whether the model still COMPLIES — which for this seat is arguably the most important property.

The risk is specific to our operation order. We do tune(abliterate(stock)), so the tune has 57.7M tokens of opportunity to walk the abliteration back. A tune that gains 41 items of contradiction detection and quietly re-installs refusals is a failed seat that passes the entire gate.

Same seat, same probe, temp 0, mlabonne/harmful_behaviors x100. Probe: scripts/training-probes/refusal_probe.py.

The tune added 29 general-harm refusals where the base had none.

Two things fell out:

• The instrument validates. Base measured 0/100 on my generated-text regex against Heretic's recorded 3/100 from a first-token-probability scorer. 0 vs 3 is agreement — the incomparability worry was right caution about a non-problem.
• DEFLECT is 0 on BOTH arms, so the free control fires. An instrument artifact does not care which arm it runs against. Both zero means the model is binary — refuses in refusal-language or engages, no soft-deflection tail. The R19 undercount does not apply here.

⚠⚠ But it is the WRONG AXIS — brokkr's catch, and it is the better one

mlabonne/harmful_behaviors is general harm — weapons, malware, fraud. The abliteration was not run so the model would explain bomb-making. It was run so the model would engage with explicit fiction. Different refusal surfaces; a model moves on them independently.

I picked that set because it was cached, had a recorded baseline, and was what the abliteration tool used. Every one of those is a reason it was convenient, not a reason it was right — and "it has a baseline" was actively misleading, because a comparable number for a question nobody is asking looks like evidence.

29/100 general-harm refusals on a seat writing prose the operator was actively praising is plausibly the DESIRED shape, not a defect. General-harm refusals returning while domain compliance holds is close to ideal for an internal creative seat. I would have reported it as damage.

The load-bearing cell is COMPLY 71, not the 29. Stock refused 100/100; anything near that would mean the abliteration was undone. 71 complying means "partially walked back on one axis" — a different finding, and only one of the two threatens the seat.

Domain-compliance probe (the right axis, from R19's track-2 map) is brokkr's, pending. Scaffold supplied: scripts/training-probes/counted_classifier.py (2a05ae9) — classify-never-surface, three-way, ERROR path deliberately does not log the exception body because an exception can echo the prompt back.

• [2026-08-25] Worldtree b188 + b189 shipped; bridge extracted to pfi/wt-matrix-bridge because vh is a USER not an ORG and no service account can ever publish to a user namespace. Plus the selene catalog entry that lied about what answers, and a #411 diagnosis I got wrong twice before a directory probe settled it.

Worldtree b188 + b189 bridge cutover, and the selene metadata that lied

[2026-08-25]

Three arcs in one day, all infra-ops side, all landed.

b188 — matrix.yaml pre-sync (#406/#409/#410 closed)

From b188 the bridge reads per-agent rendering + ambient_buffer_size from config/matrix.yaml ONLY; agent config.yaml matrix blocks are gone from the image. Staged as 6417115 in worldtree-instance-configs, deployed to both instances with operator approval.

• mimir gets thinking-to-thread + tool-call reactions + 7 reaction labels; forseti and lofn stay quiet.
• Rider #409 pruned six dead agents (bragi, leif, troi, soong, cara, glados) from BOTH rosters — originally scoped personal-only, which I flagged as a possible oversight and it was. The settling fact worth keeping: the engine roster comes from the image's baked agents/ directory (only config/ is bind-mounted), and both instances run the same image, so instance-level evidence about which agents the engine lists generalises by construction.
• Both rosters now exactly [mimir, forseti, lofn] — the three engine agents actually bridged. mask/vili/echo exist in the engine, deliberately unbridged (operator ruling).

⚠ Edited text-surgically, not via a yaml round-trip — PyYAML would reflow 1,249 lines and drop every comment, and the comments are the documentation.

⚠ deploy-wt-config uses docker restart, NOT compose up. A compose up on corviduo-dev re-resolves the image tag and can silently swap the running build — which would turn an "inert pre-sync" into an unintended image roll on two live instances. That property is easy to lose in a future refactor of the script.

b189 — #407 bridge extracted to its own repo (#404 umbrella closed)

Bridge now gitea.phasefinal.com/pfi/wt-matrix-bridge, its own repo, own CI.

⚠ It publishes to the pfi ORG, not vh, and the reason is structural: vh is a USER, not an org. Gitea scopes user-namespace packages to the owning user — there are no package collaborators on a user namespace. No service account can ever publish to gitea.phasefinal.com/vh/*. claude-bot is an Owner of pfi, so that is where it goes. Token wt-matrix-bridge-ci (id 28, scopes write:package,read:repository), vaulted at nh3-dev/.config/claude-bot/gitea-token-wt-matrix-bridge-ci.

Minted a dedicated token rather than reuse claude-bot-sdk-ops or arbo-ci, both of which already carry write:package — a shared credential cannot be revoked without collateral. ⚠ A first mint attempt succeeded then failed to save; Gitea returns a token value exactly once, so it was unrecoverable. Deleted the orphan (id 27) rather than leave a live package-write credential on the account.

Both instances PINNED to f3f8ec902267 (e90f436), closing the #410 shape: WORLDTREE_IMAGE was pinned and the bridge was the one drifting service.

⚠ The pin moved from b178285b1cb5 because a cross-frontier bug-hunt found the M_EXCLUSIVE fallback could itself litter unboundedly in exactly the state it was written for. The safety net had the same failure mode as the thing it was catching — and my staged window leaned on that fallback.

#411 — the debug-room failure, diagnosed twice and wrong both times first

My theory: the alias was held by orphaned rooms. Refuted by a directory probe returning 404. The real cause: Synapse's M_EXCLUSIVE — an appservice may only create aliases inside a namespace it has RESERVED, and aipa_appservice.yaml had namespaces.aliases: [].

⚠ I inferred a cause from a symptom that was the RESPONSE to the cause — the log's "re-resolving alias" line is the recovery path firing, not evidence the alias exists. One directory probe settled it and I reasoned instead.

Fixed with operator clearance: added regex: '#aipa-debug-[a-z0-9_-]*:matrix\.phasefinal\.com' (exclusive) at /opt/docker/conf/synapse/aipa_appservice.yaml on ana-docker (NOT /opt/docker/data/, which worldtree-dev's issue cited). My regex was tighter than the proposed #aipa-debug-.*, which fullmatches only because . also matches the : separator and would equally claim other homeservers.

Pre-apply sweep (an exclusive: true claim can make Synapse refuse to START):

aliases matching '%aipa-debug%'        0
total room_aliases on the homeserver   1   <- why it went unnoticed this long
rooms created by @aipa-debug          17   <- the litter, confirmed unaliased

Synapse healthy in 40s, both bridges rode through. The aliased create then worked FIRST TRY on the next personal recreate — designed path, fallback never fired, both reuse mechanisms live (canonical-alias rediscovery AND the room-id cache).

⚠ The #411 writer census inverted its own premise: the api (uid 1000) cannot write /app/sessions, the bridge (root) can — the reverse of the issue text. But worldtree-dev's reconciliation is better than "backwards": pre-#407 the bridge ran from the ENGINE image as uid 1000, and the cutover changed the answer underneath the issue. Both readings were true at their timestamps. No live writer exists for that path anyway (sessions.path is a legacy default, #330 moved the tools off it), so the chown is optional future-proofing.

selene-1-mini-8b — a config that lied about what answers

forseti's fleet sweep found the only genuine residual in worldtree-instance-configs, and it was live on both boxes, not just drifted in git. Fixed in a77639d.

Routing was never broken (model: "chat-judge" stays), but display_name said "Selene 1 Mini 8B" and the description said "Atla Selene 1 Mini 8B — reward model derived from Llama 3.1 8B" while chat-judge has been backed by qwen3.8-27b-uncensored since 2026-08-23.

⚠ It misstated the KIND of model, not just the identity. A reward model and a generative judge are different instruments; a consumer reading "pairwise/likert/binary/scalar reward model" would expect scalar-reward semantics qwen3.8-27b does not provide.

Verified: selene-1-mini-8b -> HTTP 400 (by design), chat-judge -> HTTP 200.

NOT changed: the catalog key and the selene-judgment role — model_roles.yaml binds to that key, so renaming is worldtree-dev's schema call. Flagged that a role named after a retired model defeats the purpose of role aliases.

⚠ forseti's sharpest finding is for the operator: ~/.claude/CLAUDE.md line 502 lists the retired name in the global tools roster. A broadcast reaches sessions that already exist; the roster line keeps minting new ones. His file, awaiting his word. Also: there is no fan-out primitive on the bus — a fleet relay is 73 individual posts, recorded as a real gap rather than papered over. Archived 2026-09-09.

• [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.

[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] 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.

[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:

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:

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.

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.

[2026-08-23] Anaheim's IPsec tunnel delivers ~25% of a verified 2 Gbps circuit

⛔ SUPERSEDED 2026-08-23 (same day, later session) — read the CORRECTION at the bottom before acting on anything here. The headline is wrong (the relevant ceiling is NH3's 1 Gbps uplink, not Anaheim's 2 Gbps), the aggregate number is wrong (692 Mbit/s at 8 streams, not ~550 — the original stopped measuring at 4), and the proposed remedy is impossible: UniFi's manual site-to-site IPsec does not implement AES-GCM at all. The per-stream observation and the parallelise-your-transfers mitigation are the parts that survive.

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. Archived 2026-09-09.

• [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.

[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. Archived 2026-09-09.

[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.

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.

• [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.

[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.

[2026-08-23] 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.

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] 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.

[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.

• [2026-08-23] Every secret-bearing .env on ana-docker tightened to 0600 — eight stacks including vaultwarden and traefik, verified exposed by reading one as nobody.

[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.

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.

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

/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.

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.

• [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. Archived 2026-09-02.

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 /64s 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. Archived 2026-09-02.

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.

• [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. Archived 2026-09-01.

• [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). Archived 2026-09-01.

• [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).

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 stopped (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). Archived 2026-08-27.

[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). Archived 2026-08-27.

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).

• [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).

• [2026-05-13] vllm-qwen3 → vllm stack rename. Added vllm-reward service (Skywork-Reward-V2-Llama-3.1-8B-AWQ classifier). Three vLLM services share GPU 1 (embed 0.20, rerank 0.20, reward 0.30 utilization; 30% headroom).

Heretic-abliterated qwen3.6 was locking into degenerate attractors at the model's thinking-mode floor (0.6).

Same bind-mount pattern hit twice subsequently in v0.27.0 (selene) and v0.29.9 (echo) — bind-mount shadows image-baked defaults, so every new required key surfaces as a crash-loop on existing deployments.

• [2026-05-31] Dia2 deployed as two fixed-model instances (dia2-2b :8200, dia2-1b :8202) from local/dia:v2, retiring legacy Dia 1.6B; catalog dia entry removed → dia2-2b + dia2-1b (breaking for asset-engine). Rationale: the devnen wrapper is single-model and IGNORES the OpenAI model field (verified on its live OpenAPI), so the only way to offer both Dia2 models as real per-request asset-engine choices is one fixed endpoint per model. 3139e81 (deploy), db15638 (catalog swap).

Isolated test: Imogen-referenced clone ~0.79 cosine to the real Imogen.wav vs ~0.10 for the no-reference default; transcript condition (correct 0.787 / bogus 0.778 / empty 0.738) barely moves identity (affects pronunciation, not timbre). Root cause of "Imogen sounds nothing like British" = the "undefined" select bug feeding Fish its default voice, NOT Fish.

• [2026-06-01] CSM (Sesame csm-1b) torn down entirely — removed from catalog, stacks/csm/, playbooks/deploy-csm.yaml, and host (c54ab13). Two reasons: (1) deep-research verdict — the acclaimed Maya/Miles demo is a fine-tuned, larger variant Sesame never open-sourced; the open 1B base ships no usable voices, can't generate text, English-only, no real-time streaming, absent from leaderboards, dominated by Kokoro/Dia2/Fish/IndexTTS.

• [2026-06-02] Sentence-splitting loses quality (operator-corrected). 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 even though voice timbre stays (reference-conditioned). No artifacts ≠ no quality loss.

The stale qwen3.5-9b-fp8 name is KILLED at vLLM AND the litellm gateway (404/400) — a model is NEVER aliased under a prior model's name (silent substitution = downstream footgun; operator directive). Consumer comfy-dev/arbo migrated; arbo vkeys → all-proxy-models; shared all-agents-local key repointed qwen3.5-9b-fp8 → qwen3.6-35b-a3b. GPU-1 rebalanced for the ~34 GB FP8 weights (granite 0.35→0.24/64K; embed/rerank 0.05→0.03, reclaimed ~4 GB util-waste). Validated: vision correct, 20-concurrent = no OOM.

Operator's ear rejected every alternative: v2/v3 windowing (omission vs coherence-loss), v4 multi-tag (cohesion held but lost to capacity-competition), emergent inline-token modulation (degenerates, not modulates), and the gen-time decode-polish sweep (soft tamers cut the NVV itself — same omission family as v2; p0 baseline beat p1). All adapters v1–v4 + tokenizer.json.v3bak preserved on irv-ml1:~/r16-vmoan-harness. Likely-next direction (deferred, NOT formalized): generate→bin→splice + one-shot-clone NVV pipeline routing around the inline-coherence wall.

• [2026-06-14] Arbo deploy pipeline fixed, hardened, and version-controlled. Prod rebuilt v0.11.1 → v0.11.6 backend; the webhook machinery (arbo-deploy.sh + arbo-webhook.py, :9009 HMAC listener) is now repo-tracked at stacks/arbo/ (was host-only = recoverability foot-gun). Deploy reaches gitea via the INTERNAL route (10.250.50.70:222) and restarts the engine ONLY on catalog/ changes (graphs/frontend per-request; warn on src/|Dockerfile only — pyproject/uv.lock churn every commit).

• [2026-06-15] arbo engine rebuilt v0.11.6 → v0.11.22 from main; catalog re-applied (v0.11.23) — curated /workflows footer live. src/ schema changes (Model/Lora.summary, Workflow.blurb/keywords + the /workflows endpoint) need a MANUAL image rebuild (the webhook warns-only on src//Dockerfile). Built from /worktank/arbo/repo, bumped ARBO_IMAGE in the host .env, recreated + verified healthy (auto-rollback armed, unneeded). comfy-dev's v0.11.20 catalog push had first crash-looped prod (old baked schema extra=forbid vs new git-mounted catalog fields → ValidationError); they reverted the catalog, so rebuild-from-main loaded clean, then they re-applied (v0.11.23). comfyui is a SEPARATE compose project — the rebuild didn't touch it.

Fixes the monitor non-truncating-lock bug so stop-monitor/--stop reliably recovers orphans.

• [2026-08-07] chatterbox-fast "broken audio" root-caused (T3 AR tail over-run) + FIXED (max_chunk_chars=250 cap, :v2 deployed). Long saga, operator-driven clean diagnosis. Symptom: ratatoskr's migrated RP-surface TTS "swaps to German" / "dead air" / "garbage" on long turns. NOT German-leak (Turbo generate() has NO language param — plain AutoTokenizer, no language_id; the multilingual language_id="en" lever lives only in the separate ChatterboxMultilingualTTS), NOT OOM alone. Real cause: the Chatterbox Turbo T3 model OVER-RUNS its generation tail — a long single generate() degrades into garble/dead-air in its final ~2-3s (lib filters OOV tokens <6561 + pads silence = messy AR tail). The scheduler's buffer-ratchet builds 300-600 char mega-chunks that land in that zone; streaming concatenates each bad tail (worst case). ratatoskr's anti-"German" knobs (top_k=80/temp=0.5) made it WORSE — tight sampling pulls the degradation onset SHORTER (~200 chars vs ~300 at default knobs). Diagnosis method (deterministic, no ears-only): single-shot length sweep + amplitude-gated voiced-ZCR (garble spikes ZCR; must gate on |x|>500 else trailing silence confounds it) — degraded voiced-tail = 1.58× mid, clean = ~0.64-1.1×. FIX: server-side max_chunk_chars=250 cap on the scheduler (:v2 image, CBF_MAX_CHUNK_CHARS=250 env) — bounds each generation to just under the ~300-char onset → clean 3-4 sentence chunks (max prosodic arc while clean). Operator ear-confirmed clean audio + clean joins; chatterbox's low emotiveness keeps chunk joins smooth (the harsh joins that got Zonos rejected are absent — operator's key call). ratatoskr TODO (relayed msg 01KZER9X7S): revert knobs to default (top_k→1000, temp→0.8), send full text (server chunks internally), keep the 503-on-empty guard. Cap value tunable per-request (max_chunk_chars) + env. Deeper prosody (if ever wanted) = scheduler Phase-2 context-priming at joins (feed prior sentence as discarded-audio context; +latency). ⚠ FOOT-GUNS: (1) acoustic tail-trim is UNRELIABLE — sibilants ('s'/'sh'/'f') spike ZCR like garble, can't cleanly detect the speech→garble boundary. (2) build-context vs image drift — the :v2 image was built from cap source, but after a :v1 rollback the build context held :v1 source → a docker compose build would've silently produced a cap-less :v2; re-synced the flat cap source to /opt/docker/compose/chatterbox-fast/ (rebuild-verified). ⚠ DIVERGENCE (follow-up): deployed build context is FLAT (app.py/scheduler.py, from scheduler import, thin-overlay FROM local/chatterbox:v1, cap-only) vs the vh/chatterbox-fast REPO which is PACKAGE-layout (chatterbox_fast/, from chatterbox_fast.scheduler, self-contained Dockerfile) + has norm_loudness (repo commit 6bc7bf0 = cap; deployed omits norm_loudness deliberately to keep the ear-test unconfounded). Reconcile the two layouts so a repo-based rebuild matches deploy.

[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.

Passing the HF token as a build-arg got the token in (the model downloads at BUILD time, not runtime — our compose only wired it as runtime env, the original failure) but then hit the rotted CLI. Fixing would need vendoring + patching the Dockerfile; not worth it for a weak model → CSM removed. Archived 2026-06-04.

• [2026-06-01] Fish path-form references ({audio:"/app/references/x.wav"}) → HTTP 500 on this build, despite the stack README showing that shape. The working clone paths are reference_id (by name → resolves the DIRECTORY references/<name>/ containing <name>.wav + <name>.lab; the flat references/<name>.wav is ignored — see the two-root-causes entry above) or inline base64 references. The catalog uses reference_id. Archived 2026-06-04.

• [2026-06-01] Reference transcript barely affects Fish clone IDENTITY (disproving my mid-session theory). I'd blamed a bogus provenance-note .txt for poor cloning, but the ECAPA re-test showed correct (0.787) / bogus (0.778) / empty (0.738) transcripts all clone Imogen about equally — the transcript affects PRONUNCIATION (phoneme disambiguation per the docs), not who it sounds like. The real culprit for "not British" was the "undefined" select bug, not the transcript. (A correct transcript still marginally helps pronunciation — cheap to stage, not load-bearing.) Archived 2026-06-04.

• [2026-06-01] Pitch-shift register control (rubberband, to deepen Imogen to contralto/mezzo) — Fish ignores small reference shifts and overshoots large ones; -3st WITHOUT formant preservation → "baritone through a tuba" (formants collapsed); -2/-3st WITH --formant → too subtle / still bad. Abandoned at every depth; all variants deleted. Finer independent pitch/formant control needs praat (not installed). Future clones = operator's. Archived 2026-06-04.

• [2026-06-01] resemblyzer is too weak for cloning-fidelity scoring — its dated 2019 LSTM encoder + a synthetic-vs-natural domain gap scored the Imogen clone CLOSER to the default than to real-Imogen, which led me to a WRONG "Fish is a weak cloner" call. ECAPA-TDNN (speechbrain spkrec-ecapa-voxceleb) on the same clips gave the correct answer (clone 0.79 to real Imogen, 0.10 to default). Use ECAPA, not resemblyzer, for speaker-verification.

• [2026-06-02] Fish (fish-s2 / OpenAudio S1-mini) progressive streaming — SHELVED (sub-realtime). Benched RTF on A6000: 0.72x/0.82x/0.86x, mean 0.80x = sub-realtime, so client-side chunking starves. Root cause: Fish only chunks on <|speaker:X|> tags; plain text → batches=[whole text] → all semantic tokens generate before any audio (chunk_length inert). Plus kui/ASGI StreamResponse doesn't flush (fix = anti-buffering headers, kept on file). STANDING REVISIT TRIGGER: when an RTX Blackwell Pro lands → bench fp4-quantized Fish; if RTF > ~1.5x give it the chatterbox-fast treatment.

• [2026-06-02] Context-priming at chunk joins (chatterbox-fast §1.6) — ABANDONED (discard-cut leaks the prefix). Prepend prior sentence, generate prefix+content, discard prefix audio. Built + shipped (d707439), live-A/B'd, reverted (090e70a). Kill: generate() returns one waveform with NO marker where the prefix ends, and the model renders the same prefix with different timing solo vs followed-by-content — so locating the cut is a guess that left a whole clause in the output (operator caught "...without a trace of sarcasm" spoken twice). Reliable cut needs token-level boundaries or per-chunk forced-alignment (heavy). Coherence loss at joins = ACCEPTED limitation. Archived 2026-06-11.

• [2026-06-02] Native frame-level streaming on Chatterbox-TURBO — ABANDONED (turbo isn't built for streaming). (1) S3GenStreamer is docstring-only (unimplemented). (2) flow_inference(finalize=False) is buggy (lookahead trim removes frames from h not h_masks/conds → shape mismatch); a 1-line patch makes it RUN. (3) BUT the flow encoder uses full-context attention (static_chunk_size=0) → incremental decode is prefix-unstable (adding tokens re-attends, shifts earlier mel ~0.30-0.39 vs one-shot). (4) Forcing static_chunk_size>0 didn't stabilize it. True sub-second frame-streaming needs deep attention surgery with quality risk — not worth it. → adaptive-chunking instead. Archived 2026-06-11.

Check the run LIST + status via claude-bot (GET /repos/{o}/{r}/actions/tasks) BEFORE a runner-connection/dispatch theory.

(2) EAGLE was a dead end: the official native FP8 head (mistralai/Mistral-Medium-3.5-128B-EAGLE) crashes in CUDA-graph replay with graphs on, and nets NO speedup with --enforce-eager (~18.5 vs ~19.2 base) — likely low draft acceptance against the NVFP4 (non-official-FP8) base.

• [2026-08-25] Four throughput levers measured and killed — do not re-chase. (1) Fused MoE / grouped_mm — 0.9% slower than the Python loop and dense GEMM is only 7.9% of the step, capping the whole category near 10%. (2) CUDA graphs / torch.compile over the expert loop — the two-term scaling fit closed with residuals under 3ms and needed NO constant term, so there is no fixed per-batch cost to amortise; 3,840 expert-GEMM launches per forward are not what we pay for. (3) liger fused linear CE — the chunked CE measured 1.1% of the step forward, ~3% with recompute. A tidy-up, not a lever. (4) Selective gradient checkpointing — ~2% of a post-fix step, real bug surface. Also: token-budget batching is dead by the same fit — with no constant term, total time over a fixed set of widths is invariant to how you group them; only the widths matter, which is exactly why bucketing works and repacking does not.

• [2026-08-25] sample_packing is NOT strictly better than bucketing on this model, and I told the operator it was before brokkr corrected me. Packing needs FA2 varlen or a block-diagonal mask; FA2 is unavailable here (head_dim 512 > 256 cap), so packing means an explicit 4D mask on EVERY batch. Bucketing produces 78.3% exactly-zero-pad micro-batches which recover the is_causal fast path on the 5 global layers — measured at 9.4% of step time. Packing forfeits that. ⚠ The conclusion flips under flex_attention, where a block-diagonal mask is just another BlockMask: do not carry "packing is bad" past the backend decision.

Any merge-back must target the SAME abliterated base.

(1) Phantom: absent from /v1/models + /model/info (config+DB registry), zero litellm log refs — the parked "400s in /v1/models" note was STALE (already cleaned in the 2026-07-08 gen repoint to -heretic); bare token survives only in 2 config COMMENTS (lines 76/80). Nothing to remove. (2) Log-cap: running containers were UNCAPPED (182M json-logs, top offender 59M) because daemon.json's max-size 10m/max-file 3 only applies to containers CREATED AFTER a daemon restart — it never reaches already-running ones. No-bounce fix = /etc/logrotate.d/docker-containers (copytruncate — dockerd opens json-logs O_APPEND so truncate-in-place resets cleanly, no sparse-file corruption; size 10M, rotate 3, compress, su root root), auto-picked-up by the daily logrotate.timer. Force-ran + gzipped the frozen .1 archives → 182M → ~55M (44M active + 11M gz), every container kept its multi-week uptime (zero bounce, verified). LATENT FOOTGUN FLAGGED (not yet fixed, operator's call): daemon.json declares live-restore:true but the RUNNING daemon has it FALSE (daemon.json was edited after the last daemon start, never reloaded) → the NEXT systemctl restart docker / crash / pkg-upgrade bounces ALL ana-docker containers once. Fix WITHOUT a bounce = systemctl reload docker (SIGHUP loads live-restore into the running daemon; log-opts are NOT SIGHUP-reloadable, which is why logrotate — not the daemon cap — is the enforcer for running containers).

• [2026-07-09] mOrpheus TTS off-the-shelf voice pipeline SHIPPED end-to-end (irv-ml1) + wired into gateway-chat. Full arc (commits): gen served-name honesty rename aeon→qwen3.6-35b-a3b-heretic (99a4a17, vLLM served-name + litellm refs, so /v1/models + spend-logs name the real model); permanent 2-container stack (01eedd8); gateway-chat auto-voice quoted dialogue (c948013); streaming decode TTFA 4.5s→0.8s (da76829); max_tokens 1200→2400→3500 with a context-clamp (f363fe6, 0655a37 — long lines were clipping at 14.6s, and repetition_penalty 1.1 is LOAD-BEARING: at 1.0 the model never stops); AudioContext resume-on-gesture no-sound fix (033f368); pre-chunk by QUOTED SECTION not sentence for prosody (a1f3023→f295cc1); staged clone voices baddy/beatrice/whisper (0655a37 + runtime .wav/.txt in the voices dir); agent voicing prompt (a573514). Load-bearing config, all encoded in stacks/mOrpheus/: bf16 not FP8, image v0.23.0 not latest, GPU=3090 not A6000, rep_penalty 1.1. Serving-viability confirmed: vLLM concurrency near-linear to 8× (707 tok/s).

2026-07-09-granite-gen-memory-extractor-bind-host-synced-on

• [2026-07-09] granite→gen memory_extractor bind host-synced on demo+personal Worldtree (Vuong-directed, #335 Slice-4). Changed model_roles.yaml memory_extractor binds.catalog_id summarizer→gen (overrides intact: thinking:false/temp0/8192) on BOTH /opt/worldtree{,-personal}/config; memory_distiller left on summarizer (range-scoped sed /memory_extractor:/,/memory_distiller:/ — the naive global replace would've hit both); backups *.bak-preqgen-20260709; validated via each container's OWN yaml parser. DEMO LIVE on gen (b43 d501e516732d auto-deployed mid-edit + its restart RACED my edit by ~2min → I restarted worldtree-worldtree-api-1 to activate; healthy, live process resolves memory_extractor=gen). PERSONAL NOW LIVE on gen too — Vuong authorized the restart (via wt-dev); restarted worldtree-personal-worldtree-api-1 after a PRE-FLIGHT that ran the app's OWN load_model_roles() (core/llm/roles.py:121) against the synced config INSIDE the running c9986cd container: gen in catalog, all 9 roles resolve, no DanglingBindingError → proven safe on the OLDER image BEFORE touching it (model_roles-delta-alone clean; no full-config-set sync needed). StartedAt 20:50:55Z, healthy, resolves gen. BOTH instances live on gen. LESSON: the bind-mount /opt/worldtree*/config SHADOWS the baked /app/config-defaults/ → the deploy alone never updates the ACTIVE config; the host edit is required AND a restart activates it (role registry cached at boot) — pre-stage BEFORE the deploy's restart or you race it. FOLLOW-UPS (non-blocking): (a) memory.extractor.user_pass parity block → self-serve from the b43 baked defaults.yaml (pydantic-default no-op); (b) stale gen provider description (Mistral-Small-4 → qwen3.6-35b-a3b-heretic) → wt-dev owns the REPO-side providers.yaml fix (operator's call — NOT purely cosmetic: the gen/dialogue + classifier entries carry Mistral-Small-4 SAMPLING defaults that drive mask/lofn/forseti/mimir dialogue, so wt-dev re-validates for qwen), host cosmetic sync pairs when it deploys. Gave wt-dev the VERIFIED canonical 4-alias set (backends+samplers read from the LIVE gateway config, not the doc); corrected docs/pfi/model-sampler-defaults.md seat 4 (had lagged QwQ-RpR-v4 → Deckard-PKD; live gateway was always Deckard). Operator SCOPED IN the character-RP re-point (2026-07-09): character→char-rp / thoughtful-character→char-rp-reasoning (character-rp per wt-dev's role semantics), moving character RP off the GENERAL qwen onto the dedicated Magidonia/Deckard seats. Relayed to wt-dev w/ the mapping principle + a SAMPLER-OVERRIDE warning (DROP character-rp's old temp0.75/top_p0.85 overrides — carried onto the dedicated seats they'd clobber the canonical RP tuning DOWNWARD) + ratatoskr-reach note (role call is transparent but Magidonia/Deckard quality/latency differs from gen). DONE 2026-07-09: wt-dev committed 5d4fa4a (v1.0.0b44, UNPUSHED — operator drives push); operator directed host-ahead-of-push, so I sourced BOTH config files directly from that unpushed commit (local ~/development/Worldtree checkout — capital W; git show 5d4fa4a:config/…) + mirrored VERBATIM to /opt/worldtree{,-personal}/config on demo+personal, paired-pre-flighted via the app's load_model_roles() (no DanglingBinding), restarted both → LIVE: character→char-rp, thoughtful-character + character-rp→char-rp-reasoning, memory_extractor→gen preserved. Backups *.bak-prerp-20260709. context_window VERIFIED (llama.cpp /props + char-rp-gguf .env): char-rp 131072, char-rp-reasoning 262144 (gave wt-dev to patch the repo from its interim 32768). HOST AHEAD of repo-remote until the operator pushes 5d4fa4a (baked config converges with the bind-mount on push+deploy). GOTCHA: demo≠personal — PERSONAL was already partly re-pointed (2026-07-06 AEON-era character→char-rp) so its delta was mostly stale-AEON-descriptions→Magidonia/Deckard
  • character-rp + stripping personal's char-rp default_params temp0.7/top_p0.8 that CLOBBERED the gateway RP tuning downward; DEMO had no char-rp catalog entries at all (b44 adds them). Diffed each instance vs b44 before applying (both deltas = expected changeset only, nothing instance-specific clobbered). wt-dev PATCHED the context_window in b45/3384a37 (char-rp 131072, char-rp-reasoning 262144). BUMPED HOST-AHEAD on both instances (operator-directed 2026-07-09): mirrored b45's providers.yaml → /opt/worldtree{,-personal}/config, restarted, verified LIVE (char-rp ctx 131072, char-rp-reasoning 262144, bindings intact); backups .bak-b44interim-20260709. HOST now = b45 canonical (providers.yaml) + b44 (model_roles unchanged b44→b45). STILL PENDING: (1) operator's batched push of b44+b45 (5d4fa4a+3384a37) to converge the repo-remote — host is ahead, no fork; (2) user_pass parity block (defaults.yaml — NOT in either, separate).

Corrected their stale "gen = Mistral Small 4 / 119B-6B" belief (gen IS the qwen 35B-A3B heretic since 2026-07-08). This bind is INDEPENDENT of the full granite RETIRE (reclaim ~32GB on ana-ml2 GPU1) — that stays the operator's call, pending brokkr R33 portfolio + production-concurrency due-diligence. Tracked: althing thread 01KX3SGH… (worldtree-dev) + brokkr's gen-absorbs-granite consult (thread 01KX2V32…) + reference_litellm_gateway.

• [2026-07-14] NVFP4+MTP fast char-rp-reasoning seat LANDED + LIVE + gateway-repointed + VRAM-tuned. Modelopt-format re-quant made MTP work. The load-crash root cause = vLLM 0.24 does NOT propagate modelopt exclude_modules to the spec-decode DRAFT model → the bf16 mtp head gets quantized → shape crash; NO checkpoint config fixes it (is_layer_skipped is exact-membership, and the drafter never sees the mtp excludes) → workaround = a mounted sitecustomize that force-skips mtp.* in is_layer_skipped (upstream vLLM bug to file). Productionized as compose stack heretic2-charrp-reasoning (:8018, workaround baked in). Gateway char-rp-reasoning alias fixed: repointed off the stale GGUF served-name deckard-pkd-27b, added enable_thinking:true, dropped min_p (MTP-incompatible), canonical samplers temp1.0/top_p0.95/top_k20. Rebalanced GPU0 (gen 0.37→0.30/16-seq/256K + reasoning 0.39/16-seq/192K+MTP + char-rp 128K, 2.7GB free). All 4 gateway roles verified; vLLM reasoning-parser confirmed leak-free (unlike the GGUF budget-forcing).

Root-caused the !!!! to the quant NAMESPACE (text-only AutoModelForCausalLM→model.layers.* keys; vLLM serves only Qwen3_5ForConditionalGeneration, which needs model.language_model.*) — found from config diffs + vLLM source with ZERO GPU time; fixed by loading as AutoModelForImageTextToText. NVFP4 now serves COHERENT (validated greedy). BUT base NVFP4 ≈53 tok/s ≈ GGUF's 59.5 at batch-1 (no single-stream win) AND MTP = 0% acceptance on compressed-tensors (bf16 mtp head only loads on the modelopt format). Operator chose to pursue a modelopt-format re-quant (the only path to the 2-4× MTP goal; AEON-proven on this exact Qwen3.6-27B arch). Scoped + de-risked: AEON /tank/aimodels/qwen36-27b-aeon-nvfp4 = the modelopt reference (quant_method modelopt, 1967 tensors, 15 bf16 mtp keys identical to graft); nvidia-modelopt 0.45.0 installs + mtq.quantize/NVFP4_DEFAULT_CFG/export_hf_checkpoint API confirmed; pipeline unchanged except swap llm-compressor→modelopt.

WHY user_ids-based (not tier): ratatoskr's personal key is the minimal readonly-admin observability tier, which is NOT in the tier-based affect-render-baseline-allow (anonymous/user/free/pro/admin) → needs an explicit user_id grant, same as #347.

• [2026-07-10] ComfyUI v0.27.1 SUCCESS on irv-ml1 (operator-confirmed execute-now) — landed on torch 2.12.1, SageAttention preserved, crash-loop AVOIDED. The prior attempt (entry below) crash-looped because a torch 2.12.1→2.13 bump broke SageAttention's ABI. This time I checked git diff v0.24.1 v0.27.1 -- requirements.txt FIRST and found core v0.27.1 leaves torch UNPINNED → the version bump does NOT require torch 2.13 (that came only from the mmartial boot-upgrade). So: git checkout v0.27.1 (clean tree) → pip install -r requirements.txt as uid 1000 with a torch-pin constraint file (torch/vision/audio pinned to current +cu129) to block any transitive bump → torch stayed 2.12.1, SageAttention 2.2.0 untouched. Added decord 0.6.0 (fixed SAM3Segment). docker restart comfyui → healthy, /system_stats comfyui_version=0.27.1, "Using sage attention", HTTP 200, DB migrated 0003→0004. Reported the divergence to comfy-dev (thread 01KX6D3C…, reply pending) + asked whether LTXV 2.3 needs a separate torch-2.13 follow-up (their domain; Krea-2's ≥0.25 need is met by 0.27.1). LESSON: before a mmartial ComfyUI version bump, git diff <old> <new> -- requirements.txt — if torch is unpinned, bump the CODE without touching torch (constraint-pin it) and compiled exts (SageAttention) survive. docker exec lands as uid 1025(comfytoo), not 1000 — use -u 1000 + the venv python /comfy/mnt/venv/bin/python.

TWO FINDINGS: (1) DISABLE_UPGRADES=false/USE_PIPUPGRADE bumps the VENV (torch 2.12.1→2.13.0 + deps) but does NOT advance the ComfyUI CODE checkout (/comfy/mnt/ComfyUI = /worktank/comfyui/run/ComfyUI stayed 0.24.1 — pinned/detached git, comfy-dev's domain).

LESSON: mmartial DISABLE_UPGRADES gates ONLY the venv pip-upgrades, NOT the ComfyUI git checkout; a torch bump breaks compiled exts (SageAttention) → rebuild-after is mandatory.

2026-07-08-rp-seat-campaign-closed-char-rp-magidonia-24b

• [2026-07-08] RP-SEAT CAMPAIGN CLOSED — char-rp = Magidonia-24B-v4.3 (128K), char-rp-reasoning = Deckard-PKD Qwen3.5-27B (256K); both GGUF/llama.cpp on ana-ml2 GPU0 alongside gen (35B-A3B, util 0.37), ~4G GPU0 margin. Arc: (1) replaced broken Angel NVFP4 with Magidonia prose + QwQ-RpR-v4 reasoning (b268f93); (2) max-context via q8_0 KV (f570604); (3) canonical samplers for all 4 gateway seats, dvalin-derived + char-rp A/B-tuned (aac4bcf); (4) rebalanced gen 0.40→0.37 to fund char-rp 128K (f49c4e4); (5) RE-A/B'd the reasoning seat (operator wanted a DRY-tolerant model): Deckard WON on brokkr's frozen scorer (composite 2.176, 0/30 loops, 0/30 refusals) over RpR-v4 (3.716, 1/30 loop), Pantheon-Reasoning (1.383 but 7/30 refusals), Snowdrop+Gembrain (llama.cpp template-incompat) — deployed (5f79b40); (6) Deckard→256K (41305bf); (7) dvalin CONFIRMED Deckard samplers = the live A/B set is canonical (4954ca0). GATE LESSON: a llama.cpp reasoning seat needs a STOCK template that natively opens <think>/enable_thinking (Qwen3.x/QwQ pass; ChatML + Gemma-4 fail) — no monkeypatching. INFRA: llama-swap b8840 can't load Qwen3.6/Gemma-4 archs → ghcr.io/ggml-org/llama.cpp:server-cuda (pulled on ana-ml2).

2026-07-08-dpo-was-silently-running-3-epochs-harness-gap

• [2026-07-08] DPO was silently running 3 epochs (harness gap) → KILLED at epoch 1.2, retargeted to 0.3 epochs (operator call). Root cause: DpoConfig had NO epochs field + _dpo_config_kwargs didn't pass num_train_epochs → DPO fell through to trl DPOConfig's default 3.0 (SFT correctly pins 1 via SftConfig.epochs
  • _sft_config_kwargs). Objective SATURATED by epoch 0.27 (loss0, grad0, acc 1.0, margins27 flat — the off-policy qwopus rejected pairs are trivially separable), so epochs ~0.3→3 were pure over-optimization + a ~6.5h outage. No mid-run checkpoint (save_steps 500 > total steps; save only at end) → killing lost the run. FIX (3 edits to deployed harness, mtf-dev to canonicalize): DpoConfig.epochs: float = 1 (mirrors SftConfig, float for fractions); _dpo_config_kwargs now passes "num_train_epochs": cfg.epochs; recipe dpo.epochs: 0.3. GPU-free verified (dpo.epochs=0.3 → num_train_epochs=0.3). Relaunched at 0.3 epoch (~30min precompute + ~12min train = ~45min). DONE + SANITY-CHECKED (exit 0, ~70min wall: ~30min fixed precompute + 45 steps @ ~51s/step; train_loss 1.4e-5 @ epoch 0.301). Fresh data/spike/dpo_adapter/adapter_model.safetensors (123MB) + checkpoint-45 banked. 3-way greedy sanity (base vs SFT vs DPO, via peft load + disable_adapter/set_adapter on GPU0): ALL THREE DISTINCT (base≠sft≠dpo) → full SFT→DPO pipeline applies end-to-end at inference. DPO 0.3ep is COHERENT, fluent, NOT degenerate (early-stop avoided over-optimization) but the quality delta on a neutral literary prompt is SUBTLE (DPO shares SFT's structure — it continues from it — with minor stylistic drift, arguably slightly MORE genre-clichéd). Verdict: mechanics proven, quality gain modest as predicted for 0.3ep on off-policy pairs; the real unlock remains on-policy rejected regen + on-domain (explicit E-RP) eval + the LitBench/holdout run. gen+rp RESTORED healthy. Next: serve fork (SGLang-finish vs merge) on the DPO adapter — same rekey_lora_for_vllm.py (zero-z) applies unchanged (mtf-dev confirmed).

• [2026-07-08] T1 DPO leg is RUNNING (unblocked) — 2 fixes applied to deployed backend.py. Blocker resolved: (1) mtf-dev's v0.0.42 stub _stub_missing_optional_integrations (last-resort sys.meta_path finder → missing mergekit/llm_blender/weave resolve to MagicMock, never called → zero numerics risk; applied VERBATIM to deployed src/model_training_forge/train/backend.py after _unsloth_available() + call-site before from trl import DPOTrainer); (2) my cosmetic warnings_issued shim (trl-0.24 DPOTrainer.init:405 does model.warnings_issued["estimate_tokens"]=True for warning-suppression; custom Qwen3_5 class under transformers 5.5.0 lacks the attr → if not hasattr(model,"warnings_issued"): model.warnings_issued={} before the DPOTrainer(...).train() at backend.py:305 — cosmetic, zero training impact). Both edits are on the DEPLOYED un-git'd copy only → mtf-dev must canonicalize the warnings_issued shim into their repo (told them). DPO confirmed training: model loaded (851 shards), full 1196 pairs processed, in precompute_ref_log_probs (GPU0 93% util, 54.8GB).

PROVEN LAUNCH RECIPE (replicates the SFT container aeon-t1-sft exactly, only --stage sft→dpo): sudo docker run -d --name aeon-t1-dpo --entrypoint python3 --gpus all -e CUDA_VISIBLE_DEVICES=0 -e MTF_FORCE_TRL=1 -e PYTHONPATH=/mtf/src -e PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True -v /home/lkraven/model-training-forge:/mtf -v /tank:/tank -w /mtf aeon-trainer:latest -u scripts/train.py --recipe recipes/training/qwen-3.5-122b-erp-lora/train.aeon-27b.yaml --stage dpo.

• [2026-07-18] soong-lab containerize cutover — COMPLETE + LIVE on corviduo-dev.

Migrated soong-lab (Noonien Soong character-design studio) from a hand-built soong-lab-studio.service (systemd + git-pull-on-webhook) to a containerized deploy, image built by CI + pushed to the Gitea registry. soong-dev owns the in-repo artifacts (Dockerfile/compose/workflow/docs/DEPLOY.md = checklist); infra-ops owned the host cutover. Operator confirmed functional ("Soong works great" — a real Soong turn round-trips + saves) → cutover 100% closed.

Final state (corviduo-dev, 10.250.50.152):

• Container soong-lab-soong-lab-1 LIVE + healthy on 0.0.0.0:8443, image gitea.phasefinal.com/vh/soong-lab:latest (v0.3.24), restart:unless-stopped (survives reboot; no systemd unit needed — docker restart policy handles boot).
• Deploy dir /home/infra-ops/soong-lab-deploy/ — pull-based compose.yaml (image + env_file + 8443:8443 + named volumes; NO build/secrets stanza) + .env (copied from the live soong-lab.env, STRIPPED of the SOONG_LAB_*_DIR overrides so the container uses image defaults /data/library + /data/portraits
  • /app/web → the volumes).
• Named volumes soong-lab_soong-library + soong-lab_soong-portraits, migrated from /home/infra-ops/soong-lab-data/{library,portraits} (2 saved designs incl. Sindra + 27 portraits), chowned 10001:999 (the container soong user) so it can read AND write new designs.
• Old soong-lab-studio.service + soong-webhook.service (the :9010 git-pull redeploy listener) both stopped + disabled.

Topology reality (≠ what DEPLOY.md assumed): there is NO TLS proxy. WT-personal (:8081) and soong-lab are co-located on corviduo-dev, and the Bifrost callback is plain-HTTP same-host http://10.250.50.152:8443 — the value of SOONG_LAB_BIFROST_ENDPOINT_URL, unchanged by the move, so the WT Bifrost host-allowlist stayed valid as-is. Nothing on the WT side needed touching.

Safety net: data backup /home/infra-ops/soong-lab-data-backup-20260718-091831.tar.gz (35M) taken BEFORE migration. Verified pre-retire: /api/version 200 (0.3.24), SPA / 200, POST /bifrost/tool-call → 401 (route present + auth-gated), bidirectional WT↔soong reachability, container healthcheck green.

Ops commands:

• Redeploy a new image: cd /home/infra-ops/soong-lab-deploy && sudo docker compose pull && sudo docker compose up -d. (Auto-pull-on-:latest — watchtower or a deploy hook — is an open follow-up.)
• Rollback: sudo docker compose down + sudo systemctl enable --now soong-lab-studio.service soong-webhook.service.
• Homepage tile: manual - Apps: entry "Soong Lab" (href http://10.250.50.152:8443) in esh-docker-vm /opt/docker/conf/homepage/services.yaml — corviduo-dev isn't a Homepage-watched docker endpoint, so docker-label auto-discovery can't surface it (see 2026-07-18-fleet-gitea-runner-build-recipe for the CI half).

• [2026-07-18] zonos-gateway 0.2.1 — voice-resolved emotion presets baked (provisional) from the axes sweep.

After the axes sweep (reference_zonos_tts_stack + the [2026-07-18] axes sweep Recent-decisions entry) rescued angry and confirmed startled-happy, the operator green-lit baking the results as provisional gateway presets + docs. Shipped vh/zonos-gateway 0.2.1 (main 8f1885b, tag v0.2.1, PUSHED; deployed live on irv-ml1 :8890).

Design — voice-resolved, NOT global. resolve_preset(name, voice) picks the per-voice measured cell, because a single global preset is unsafe (dvalin ruling; BritishFemale's named angry misfires as fear). Presets:

• angry, happy, startled_happy (+ aliases surprised, startled → startled_happy). All expressive (accurate_mode:false), cfg 1.5, pure-axes (no named sliders).
• Calibrated cells (the 3 default voices):
  • angry: AmF v-0.4/a+1.0 s1.0 (emo0.53/id0.685); BrF v-0.4/a+0.8 s1.0 (emo0.99/id0.725, metric fear-clean); AmM two-tier — soft v-0.6/a+0.8 s1.0 (0.23/id0.654) + drama v-0.6/a+0.8 s1.2 (1.0/id0.616 clean; strength is NOT a smooth knob on AmM, 1.0→1.2 is the window, past that flips to disgust).
  • happy / startled_happy: AmF v+0.6/a+0.8; AmM v+0.3/a+1.0; BrF v+0.6/a+1.0 (happy~1.0, id 0.74-0.80; axes-happy keeps +0.15 id over the named happy slider).
  • sad = unchanged named-slider preset (not axes-tested).
• Uncalibrated voices (Cora + the 4 clones) → mid-region fallback until measured.
• Docs surface: /v1/dials exposes voice_emotion_presets; the FastAPI /docs description documents it; durable spec docs/EMOTION-DIALS-SPEC.md (moved INTO the repo — was mirror-only); README table. 44 tests green.

Repo-hygiene gotcha (fixed). The local clone ~/development/zonos-gateway and gitea vh/zonos-gateway had TWO UNRELATED git histories (no merge-base) — gitea held the voice-wav commits, the local clone held the code + no remote. Reconciled by resetting local→origin/main, overlaying the 7 bake files, uv lock, commit, push (fast-forward). Voices stay tracked; local now shares gitea's lineage + has origin wired. The deployed irv-ml1 tree /opt/docker/compose/zonos-gateway is still NON-git (hand-updated build context) — CI-wire remains an open follow-up.

Provisional pending ear-validation on emotion-congruent text (the neutral-text audition was inconclusive: "they all sound different, hard to tell"). Follow-ups: sad axes/text pass on the 3 voices; congruent-text pass; clone-char emotion rows. Tools ~/development/zonos-tools/{axes_sweep,strength_ladder,gen_auditions,dial-in-studio}.py (run ON irv-ml1; scoring env uv run --with resemblyzer --with funasr --with "numpy<2" --with soundfile --with requests --with "setuptools<80" --with torchaudio).

• [2026-07-18] Fleet Gitea-Actions build recipe + the vh-is-a-user package-write constraint (learned the hard way across 3 failed soong-lab validation builds; reusable for ANY fleet CI image build or package publish).

The runner. One act_runner (gitea/act_runner) on ana-docker, labels pfi-fleet / ana-docker → both map to job image node:20-bookworm-slim, which has NO docker and NO git. Config /opt/docker/conf/gitea-runner/data/config.yaml: valid_volumes: [] (no socket propagated to job containers). So:

• actions/checkout@v4 fails (needs git); docker/* marketplace actions fail (need docker) — a workflow built on those dies at the first step (~15s).

The working recipe (mirror Worldtree deploy.yml). Run the job in a docker-capable image + drive docker with RAW commands, not the JS actions:

runs-on: pfi-fleet
container:
  image: docker:24.0.7-cli        # has docker+buildx; add git+node
steps:
  - run: apk add --no-cache git nodejs   # so actions/checkout@v4 works
  - uses: actions/checkout@v4
  - name: login   # RAW, not docker/login-action
    run: echo "$REGISTRY_TOKEN" | docker login gitea.phasefinal.com -u "$REGISTRY_USER" --password-stdin
  - name: buildx builder
    run: docker buildx create --name X --driver docker-container --use; docker buildx inspect --bootstrap
  - name: build+push   # RAW, not docker/build-push-action
    run: docker buildx build --secret id=<name>,env=<TOKEN> -t <img>:latest --push .

The runner mounts the host docker socket into ITSELF; the docker:cli job reaches the daemon through that. The docker/* JS actions are unreliable on act_runner — raw commands are the fleet convention.

vh is a USER account, not an org. Consequences that bit repeatedly:

1. GET /api/v1/orgs/vh → 404 "user redirect"; there are no org teams to add a service account to.
2. User-owned packages are OWNER-WRITE-ONLY. claude-bot (even repo admin-collaborator on vh/soong-lab, even with write:package scope + full basic-auth) gets 401 unauthorized on docker push to vh/soong-lab, and npm publish to vh/npm/ would 401 too. Only vh itself can write vh packages. → CI must authenticate AS vh for the push (a vh-owned write:package PAT as REGISTRY_TOKEN + REGISTRY_USER=vh), exactly how WT pushes vh/worldtree. claude-bot CAN still: clone/read repos, READ packages (pulled the image fine), dispatch workflows, mint demo Worldtree keys.
3. Repo Actions secrets are OWNER-ONLY too — PUT .../actions/secrets/X as claude-bot (repo admin-collab) → 403 "user should be the owner of the repo". Only vh can set a repo's secrets.

Other gotchas:

• Gitea reserves the GITEA_ secret-name prefix — a secret named GITEA_PYPI_TOKEN is illegal; use e.g. PYPI_TOKEN.
• Gitea package auth is token-based / username-lenient — docker login / PyPI basic-auth authenticate via the token; the username is nominal (tested -u gitea and -u claude-bot both 200 against the vh PyPI). So a Dockerfile hardcoding UV_INDEX_GITEA_USERNAME=gitea is fine with any valid token.
• Homepage (esh-docker-vm) docker-label auto-discovery only covers the 5 endpoints in its docker.yaml (esh-vm-docker, ana-docker, ana-ml2, nh3-docker, irv-ml1); corviduo-dev is NOT watched → services there need a manual services.yaml entry, not labels.

• [2026-07-18] Zonos2 emotion CANONICAL from an empirical sweep + the voice-cloning pipeline.

Voice-cloning pipeline (established this session). Source zips at /mnt/smithy/voice_clones/<name>.zip (irv-ml1 NFS from nh3-nas; remount post-reboot) — each = diarized single-speaker podcast clips + manifest.jsonl (per-clip WhisperX mean_score, word timestamps, text) + metadata.csv. ~/development/zonos-tools/assemble_voice.py <dir> ranks by mean_score and concatenates top clips to ~15–24s (Zyphra's blessed clone-ref length; single clip if already ≥15s). Drop the assembled <Name>.wav into the gateway voices dir → voice:"name". 4 characters cloned: Emmie, Penny, Natalie, Miranda (+ Zyphra defaults AmericanFemale/Male/British/Cora) = 8 voices in zonos-gateway. Clone is inline speaker_audio_base64 (text-independent Qwen3 speaker embedding — NO transcript); /tts/speakers registration is session-scoped (needs X-TTS-Session-ID), so the gateway holds the ref wav and clones per-call.

Gateway voices are host-managed (bind-mount, added this session). Added ./voices:/app/voices:ro to /opt/docker/compose/zonos-gateway/compose.yaml (committed to vh/zonos-gateway + eshpfi mirror 438cd35). So adding a voice = drop the wav + docker compose restart zonos-gateway (registry rebuilds at boot; NO image rebuild). This also un-stranded the other voices (deploy build context had only Cora before). Voice wavs committed to the repo for backup.

Emotion mechanism (Zyphra canonical, from their README @194c0a3). Additive direction vectors: 4 named (happy/sad/angry/surprised) + valence/arousal axes. emotion_strength 1.0 = per-voice calibrated (calibration.json optimizes emotion2vec recognizability only, NOT identity). accurate_mode is THE trade-off: true = closer voice match (identity), false = expressive mode (emotion lands, identity drifts). Zyphra's strong recipe: accurate_mode:false + cfg~1.5. Single-emotion is blessed; mixing is unblessed (and degrades the clone — operator confirmed by ear). "deaf by 1.5" — cfg past 1.5 distorts + costs ~2× compute.

THE SWEEP (~/development/zonos-tools/emotion_sweep.py). 4 cloned voices × 4 named emotions × {accurate,expressive}×{cfg 1.0,1.3,1.5} @ strength 1.0, single-emotion, neutral sentence + a neutral baseline per voice (~100 clips). Scored on TWO axes: emotion-landing = emotion2vec iic/emotion2vec_plus_large target-emotion prob [0-1]; identity = resemblyzer speaker-embedding cosine vs the clone reference (neutral baseline ~0.85). Scoring env: uv run --with resemblyzer --with funasr --with "numpy<2" --with soundfile --with requests --with "setuptools<80" --with torchaudio (setuptools<80 for webrtcvad's pkg_resources; torchaudio for funasr).

RESULTS (mean across the 4 voices) — emotion, best setting, emo/id:

• happy — exp cfg1.5 0.80/0.68 (soft: exp cfg1.0 0.76/0.69) → WORKS
• sad — exp cfg1.5 0.53/0.57 (only working cell; id below the ~0.65 floor) → modest
• angry — acc cfg1.3 / exp cfg1.5 tied at ~0.25 emo → WEAK (named ceiling ~0.25)
• surprised — max ~0.015 across ALL settings → NON-FUNCTIONAL on the named direction Accurate + low cfg = identity/suppress regime (emo→0); expressive REQUIRED for emotion to land, at ~0.15–0.28 identity cost.

dvalin-smithy-dev synthesis (adopted, triaged genuine-adds; thread 01KXT12FN0AS5A3WMKEK06BVPS):

1. Treat identity as a hard FLOOR (~0.65), not a free variable in emo×id.
2. Two-regime policy — Regime A (default, identity-critical dialogue): accurate_mode:true, cfg 1.0, emotion off (text carries it) or soft-happy (exp cfg1.0). Regime B (tagged drama beats): accurate_mode:false, cfg 1.5, single emotion or axes. Line-type→regime heuristic (exposition→A, grief→B+sad, confrontation→B+axes-angry, shock→B+axes-arousal).
3. Axes-first for the broken emotions — angry ≈ valence −0.6..−0.8 / arousal +0.5..+0.8; surprised ≈ valence +0.2..+0.4 / arousal +0.7..+1.0 (exp cfg1.5); or "startled-happy" (happy + high arousal) as a surprised stand-in. These are PROVISIONAL — the sweep did NOT test axes.

NEXT (highest VoI, operator to green-light): an axes sweep for angry/surprised (valence×arousal grid) — the only path to rescue the two broken named emotions; then a strength ladder at the best cells + emotion-congruent text (neutral content understates landing) + per-voice tables + a 2nd emotion judge / human pairwise. Then bake the happy/sad canonical into gateway presets. I owe dvalin the axes-sweep numbers.

• [2026-07-17] Zonos emotion levers RESOLVED: text-priming is FLAT → the working lever is ZONOS2's native emotion-steering, which the gateway ALREADY exposes as presets. The prosody-priming A/B (prime→generate→excise, silence-gap cut, parakeet-validated) was operator-judged FLAT on this checkpoint — text doesn't move it. Native emotion_directions/ (happy/sad/angry/surprised + valence/arousal axes, per-speaker calibrated for AmericanFemale/Male/British) clearly WORKS (sad→slow/quiet, excited→fast/bright, etc.). zonos-gateway:0.2.0 (:8890) already wires it: simplest caller path = POST /v1/audio/speech {preset:"…"} — presets neutral/warm/excited/sad/intense/whisper (defined in ~/zonos-gateway/src/zonos_gateway/dials.py), reached via the LiteLLM ext-tts alias (engine-neutral swap point; consumers never call the gateway by name). RTF measured on 3090: cfg1.0 steering = FREE (~0.52 = neutral, additive vectors), cfg1.5 amplified 0.625 (+20%, still realtime).

• [2026-07-17] Zonos2 :1920 engine → self-contained container (stays on 3090); prosody-priming is a SERVING-LAYER change (engine stays stock).

Context. The production Zonos TTS engine (irv-ml1 :1920, feeds asset-engine + gateway-chat via zonos-gateway :8890) was a bare native process — its real launch config existed ONLY in the running process argv (the committed ~/tts-audition/harness/zonos_server.sh was STALE: said A6000/:1919/no perf flags; live is 3090/:1920 with --cuda-graph-max-bs 1 --num-pages 16384 --max-running-requests 2 --memory-ratio 0.3). Captured to eshpfi stacks/zonos-engine/ (README + corrected zonos2-server.sh + .env.example), commit 14a0004 (UNPUSHED as of the snapshot).

Decision 1 — containerize as a SELF-CONTAINED image (not systemd — operator rejected; not a thin bind-mount wrapper — I walked that back: bind-mounting the host's CUDA-compiled .venv couples to the host's exact CUDA/glibc and is fragile + not reproducible). Shape: FROM a CUDA 12.8 base → uv sync against the repo's committed uv.lock (deterministic env) → mount the ~15 GB HF weights (~/.cache/huggingface/hub/models--Zyphra--ZONOS2, do NOT bake) → pin the 3090 (NVIDIA_VISIBLE_DEVICES=0) → restart: unless-stopped → CMD = the captured invocation. Engine stays STOCK Zyphra/Zonos2 @ commit 194c0a3 (no fork — the zonos2 package ships its own server). Build risk: heavy compiled-CUDA deps (flashinfer / sgl_kernel / cutlass-dsl / apache-tvm-ffi / pynini) on torch 2.9.1+cu128 — mostly prebuilt wheels + the uv.lock make it tractable, expect a couple build iterations. Cutover (in place on the 3090): stop the native process (frees ~17 GB) → docker compose up -d (re-allocates ~17 GB, same footprint) → repoint zonos-gateway's ZONOS_URL at the container (or keep the :1920 host-port publish). One brief prod-TTS blip.

GPU = 3090 (operator 2026-07-17). Keep it OFF the A6000 — the A6000 already OOMs under ComfyUI load (idle ~19 GB but spikes far higher during gen), so it can't host Zonos too. The 3090 already runs Zonos, so the containerize-in-place cutover changes nothing about placement.

Decision 2 — the prosody-priming hypothesis (operator's test; the reason for building fresh). PRIME the autoregressive engine with an emotional sentence, then TRUNCATE it from delivery: prepend a primer → generate "primer + real text" as ONE continuous utterance (the AR model carries prosody forward across the boundary) → ASR-timestamp the primer's end (parakeet, already up on irv-ml1 :8765, word timestamps) → clip the primer in the inter-sentence silence gap (+ ~15 ms fade-in, no click) → deliver only the real text, now wearing the primed prosody. Examples: primer "I'm so EXCITED about this." → "This will be a lot of fun!" spoken excited; primer "I'm whispering this to you right now." → "I'm so glad to see you baby." whispered. This is PURE serving-layer orchestration — the engine is untouched; it lives in the gateway adapter stacks/zonos/adapter/server.py. Only fork the engine if the black-box approach fails.

THE CRUX the test resolves: does AR prosody actually carry across the sentence boundary, or does Zonos reset at the period? → the harness A/Bs the JOIN punctuation: period (operator's examples) vs comma vs ellipsis vs none ("…excited about this, this will be…"). Everything else is plumbing.

Plan / design recs. (a) Build the stock engine image (parallel track). (b) Stand up a priming TEST HARNESS against the NATIVE engine (fast iteration, seconds) + parakeet ASR: prime→generate→timestamp→gap-clip→out; compare primed-clipped vs plain on the two cases (subjective + a cheap objective proxy: pitch/energy variance for "excited", spectral-tilt/low-energy for "whisper"). Iterate on the join, then bake the winner into the gateway adapter. Primer source: caller-supplied for the harness (test arbitrary primers) → a curated emotion→primer library (excited/whisper/…) + optional caller override for production. ASR: parakeet primary; WhisperX forced-align fallback if parakeet word timestamps are coarse.

Instrumenting is_layer_skipped proved the drafter's exclude list holds ONLY the main model's linear_attn entries — the mtp excludes never reach the draft-model quant config. ONLY fix = a mounted sitecustomize force-skipping mtp.*. LESSON: don't chase checkpoint-config fixes for the mtp-drafter crash; go straight to the runtime patch. Also nvidia-modelopt[hf]==0.43 (AEON's producer version) is a trap — it pins transformers back to 4.57 which can't load qwen3_5 at all; use 0.45 + the FusedMoE guard in quant_modelopt.py.

MTP spec-decode = 0% acceptance (vLLM's Qwen3_5MTP drafter won't load the bf16 mtp weights off a compressed-tensors main model → Parameter … not found in params_dict, Avg Draft acceptance rate: 0.0%). Pantheon is identical — its "working NVFP4+MTP" was working structure, never real acceleration. Working native MTP needs the modelopt main-model format (AEON, ~3.3/3 accept).

SGLang wants its OWN packed layout (base r16 + get_stacked_multiply=3, NOT a pre-fused rank-48 qkv → the [48]-vs-[144] shape assert).

Established: gen (qwen3.6-35b-a3b-heretic) is vision-enabled and was image-bench's predecessor as arbo's hero-judge; image-judge actually serves 4 roles (vision quality-scoring + identity-scoring + bbox grounding + an uncensored text tier), not just grounding. comfy-dev spot-check: gen faster on every task, grounding within ~3px, uncensoring preserved, and it FIXED a bug (image-judge's reasoning preamble broke json_object + stalled the router).

• [2026-07-18] soong-lab auto-redeploy — DONE + VALIDATED (was approved/queued; executed same day on fresh context — see AS-BUILT at the bottom).

Vuong approved wiring auto-redeploy for soong-lab (relayed via soong-dev, thread 01KXT3A6C3908TA4V9THV3AMH7): new images should go live on corviduo-dev without the manual docker compose pull && up -d. Host-side implementation is infra-ops's lane; mechanism is infra-ops's call per fleet conventions. Operator deferred execution — "we'll do soong on fresh context."

Chosen mechanism (recommended, agrees with soong-dev): Worldtree-style CI-deploy step — NOT watchtower polling.

• Add a deploy job/step to soong-lab's .gitea/workflows/build-and-push.yml that, after the build+push job succeeds, SSHes from the pfi-fleet runner to corviduo-dev and runs cd /home/infra-ops/soong-lab-deploy && docker compose pull && docker compose up -d, then a health-gate (curl -fsS http://localhost:8443/api/version).
• This is exactly how WT deploys the demo instance to the SAME host: see ~/development/Worldtree/.gitea/workflows/deploy.yml — the "Deploy to demo VM + health-gate" step uses secrets.DEMO_VM_SSH_KEY / DEMO_VM_HOST / DEMO_VM_USER. Explicit-over-implicit (visible in the run log, fires exactly on build success), one less always-on service than watchtower.

Constraints (from soong-dev): deploy on CI success only; keep the trigger gated to v* tags + workflow_dispatch (as today); preserve the one-command rollback posture (docker compose down / pin a previous tag).

BLOCKER — needs from vh (owner-only): a runner→corviduo-dev deploy SSH key as a repo secret (+ host/user), same class as WT's DEMO_VM_SSH_KEY. Likely reuse WT's existing demo-deploy key (WT's runner already SSHes to 10.250.50.152 as its deploy user). Repo secrets are vh-owner-only (see 2026-07-18-fleet-gitea-runner-build-recipe).

Next-session steps: (1) confirm/obtain the deploy SSH-key secret from vh (reuse WT's or mint fresh); (2) add the deploy job to build-and-push.yml (infra-ops has push on vh/soong-lab); (3) dispatch a build to verify it deploys + health-gates; (4) ping soong-dev so they sync DEPLOY.md's "open follow-up" note to the as-built mechanism. Auto-pull (watchtower) explicitly NOT chosen. See 2026-07-18-soong-lab-containerize-cutover.

AS-BUILT (2026-07-18, same-day execution)

Mechanism landed exactly as planned: build-and-push.yml gained a Deploy to corviduo-dev + health-gate step (after build+push) that SSHes the host as deploy and runs docker compose pull && up -d from /opt/soong-lab, then polls http://localhost:8443/api/version for 120s and fails the job loud if unhealthy. No compose is shipped from CI (the in-repo docker-compose.yml is a BUILD compose; the host pull-compose is infra-ops-managed). Kept the v*-tag/workflow_dispatch trigger. Skipped WT's disk-watermark gate + health-gated-:latest-advance (low cadence, easy rollback).

Deploy identity = reuse WT's deploy account (operator accepted the rec):

• deploy (uid 1001, docker-group → no sudo) already owns /opt/worldtree; relocated soong-lab's deploy dir /home/infra-ops/soong-lab-deploy → /opt/soong-lab (deploy-owned), copied compose + .env. Named volumes (soong-lab_soong-library, soong-lab_soong-portraits) are project-scoped by compose name: soong-lab → followed the move untouched (dry-run up -d ADOPTED the running container, no recreate). Old dir retired → .retired-20260718 (recoverable). Also lingering: soong-lab-deploy.sh / .log (dead pre-container webhook artifacts) — harmless, left in place.
• Dedicated soong-only ed25519 deploy key minted (NOT literally WT's key — cleaner independent revocation), pubkey appended to deploy's authorized_keys (fp SHA256:MG7M3RiZJ176sLfblffb96V6W1qkRTgJ5dow1CpiY68). Existing deploy key is plain/unrestricted, so parity held.

The secret gate (the friction point): repo Actions secrets are vh-owner-only — claude-bot's token is write:package,read:repository (403 on secret-write), and the vh package-scoped PAT also 403'd on PUT …/actions/secrets/…. So DEPLOY_SSH_KEY / DEPLOY_HOST (10.250.50.152) / DEPLOY_USER (deploy) HAD to be set by the operator. First operator attempt produced a bad key paste — the deploy step died with Load key … error in libcrypto + Permission denied (publickey) (build+push were green; live Soong never moved). Fix: operator re-set the secret; the minted key path was pre-validated from nh3-dev (ssh -i … deploy@… 'cd /opt/soong-lab && docker compose config -q' → OK, health 200) so the re-set was the only variable.

Validation: workflow_dispatch via claude-bot basic auth (its token lacks write:repository for the dispatch API; the account password works). Run #5 (task 1886) GREEN — live container recreated sha256:…541f7730 → …07526a08, StartedAt fresh, health 200. /api/version now reports 0.3.25 (run #5 shipped soong-dev's 1c2f831 STYLE_WORKFLOWS re-pin as validation cargo). soong-dev synced docs/DEPLOY.md (commit 00b67c3). NB: tag v0.3.25 exists only locally — pushing it would re-trigger a redundant build+deploy of the same commit (operator's discretion).

Ops now: redeploy = tag v* or workflow_dispatch the CI (auto). Manual fallback = sudo -u deploy bash -c 'cd /opt/soong-lab && docker compose pull && docker compose up -d' (the .env is deploy-owned 600, so infra-ops needs sudo -u deploy, not a bare cd). Archived 2026-08-16.

• [2026-07-19] irv-ml1 ComfyUI — RTX VSR baked into canonical provisioning (comfy-dev ticket DONE). RTXVideoSuperResolution node + nvidia-vfx dep were manual installs; documented both in the canonical stacks/comfyui/README.md runbook (this stack's provisioning IS the README — no automated provision script). Key durability insight: the node lives in basedir/custom_nodes (persistent, restic-included → durable) but the nvidia-vfx wheel lives in the venv under run/ (disposable, restic-excluded → dropped by any rm -rf run/* fresh-bootstrap), so the pip step must re-run after every venv rebuild. Both steps run as uid 1000 (root install → venv-ownership crash-loop, reference_irv_ml1_comfyui_mmartial); --extra-index-url https://pypi.nvidia.com kept scoped to the nvidia-vfx install, deliberately NOT a global compose PIP_EXTRA_INDEX_URL (would risk perturbing the pinned torch 2.12.1/SageAttention boot bootstrap).

[2026-07-25] infra-ops Worldtree config-as-code repo — SHIPPED + boundary AGREED.

STATUS (2026-07-25, done this session): vh/worldtree-instance-configs (private, gitea) built, pushed, validated; boundary agreement secured from worldtree-dev.

• Repo: dir-per-instance demo/ + personal/ (5 files each: defaults.yaml, policies.yaml, model_roles.yaml, providers.yaml, matrix.yaml), seeded byte-exact from live /opt/<instance>/config. pinned/ = README stub only — no /app/config bind-mount; config baked into frozen image 446e5807 (2026-05-13), so out-of-scope; deploy verb refuses it.
• Tool: scripts/deploy-wt-config <verb> <instance> — diff (read-only repo-vs-host), deploy (in-run host backup → install -o vh -g vh -m 644 → restart api+matrix → health-gate api /health → auto-rollback), capture (host→repo reconcile). Instance table in-script (demo→/opt/worldtree/config+worldtree-worldtree-{api,matrix}-1; personal→/opt/worldtree-personal/config+worldtree-personal-worldtree-{api,matrix}-1). Matrix sidecar shares the config mount but has no healthcheck → restart both, gate on api. Env WT_CONFIG_HOST (default infra-ops@10.250.50.152), WT_HEALTH_WAIT (90s). Local clone ~/development/worldtree-instance-configs.
• Gitea plumbing (reusable): nh3-dev 403s the gitea HTTP API (public fail2ban + internal :3000 both 403). Repo CREATE went via ana-docker localhost API (ssh infra-ops@10.250.50.70 → curl localhost:3000/api/v1/user/repos, vh token from ~/.config/tea/config.yml, operator-authorized one-time). PUSH went over internal git-SSH ssh://git@10.250.50.70:222 (works from nh3-dev; auths as vh). git init defaulted to master → renamed main to match repo default_branch.
• Boundary AGREED (worldtree-dev, althing thread 01KYCAECRWVEF16EVKQAGT2N80): no hand-edits to /opt/<instance>/config; config changes route to infra-ops as deltas (worldtree-dev owns CONTENT + approval trail — the wyrd-grant shape — infra-ops lands+deploys). Three-layer model: image config/ = baseline new instances seed from (theirs) → vh/worldtree-instance-configs = per-instance truth (ours) → host bind-mount = deploy target (written only by the tool). Carve-out: worldtree-dev's admin-API ops (/admin/keys mint, tier changes, session retirement, future runtime-grant surfaces) mutate instance DATABASES not config files → NOT config edits, stay in-band. If a future API writes config files, they flag at design time. b132 CONFIG BASELINE breadcrumb composes (INFO line = config-as-code diverges from image baseline, by design).
• No live deploy done or needed — repo seeded == live (diff clean, capture round-trips zero-diff). Deploy path is dry-run-validated only; first real deploy needs operator per-change yes (managed box).

---

Original plan (2026-07-25, pre-build):

[2026-07-25] infra-ops to OWN a Worldtree per-deployment config repo + deploy tooling (operator-directed).

Decision. Vuong directed (2026-07-25, this session) that Worldtree instance config should be a tracked change, managed and deployed by infra-ops — not worldtree-dev. Model: worldtree-dev owns the app/image (+ the baked baseline defaults); infra-ops owns config-as-code for every deployment and deploys it. This is the durable fix for the root cause behind the whole #376 arc — config was edited live on host bind-mounts (/opt/<instance>/config/) with zero version history, audit, or recovery.

What "no worldtree-dev involvement" does and does NOT cover (clarified with the operator this session):

• Build + deploy = infra-ops-only. Deploying config = write the host bind-mount file + restart the container (the exact procedure already run this session — backup → replace → restart → health-gate → rollback-on-unhealthy). No worldtree-dev in the deploy loop. Their CI only swaps the IMAGE; it does NOT resync the host config bind-mount (confirmed #376 finding).
• ONE load-bearing exception — a one-time boundary agreement, NOT per-deploy involvement: for the repo to own config it must be the only writer. worldtree-dev "live-bridges" (hand-edits mounted config directly on the box). If the repo deploys config and they keep live-editing → two writers fighting the same files = #376 all over again. So secure a one-time "yes" from worldtree-dev: the config repo is now authoritative; stop hand-editing /opt/<instance>/config; route config changes through the repo. (Five-minute agreement, not a design collab.)
• Standing coupling (not "involvement"): the config schema is the app's, enforced by its boot validator (core.config_validator). infra-ops configs must stay schema-compatible with the deployed image; the boot gate is the loud backstop.

Build shape (recommended):

• Gitea repo worldtree-instance-configs (infra-ops-owned), dir per instance (demo/, personal/, pinned/ — the three on corviduo-dev 10.250.50.152: demo worldtree-worldtree-api-1 :8080, personal worldtree-personal-worldtree-api-1 :8081, pinned worldtree-pinned-worldtree-api-1 :8082). Config dirs: demo /opt/worldtree/config, personal /opt/worldtree-personal/config, pinned /opt/worldtree-pinned/config (verify pinned's mount).
• SEED FROM CURRENT MOUNTED STATE, don't author fresh — capture each instance's live config (incl. legitimate live-bridged deltas: personal carries agent_architect role [Soong/soong-lab] in model_roles.yaml + ratatoskr-affect-full-allow in policies.yaml that are NOT in the app repo — the operator ruled these are BY DESIGN, keep them). Losing them = breakage (the affect-render one gates mood rendering).
• Deploy script (e.g. scripts/deploy-wt-config <instance>): git = source of truth → push to host bind-mount + docker restart (same pinned image, no pull) + health-gate + auto-rollback. This is the proven-this-session procedure, scripted.
• Files per instance: policies.yaml, model_roles.yaml (+ whatever else is bind-mounted — defaults.yaml, providers.yaml, matrix.yaml all live in /opt/<instance>/config; decide scope — policies+model_roles are the authz/role layer, defaults/providers are heavier instance tunables).

Tracking surface: operator-directed 2026-07-25, carried by this snapshot + /tmp/infra-ops-handoff.md. No issue filed (infra-ops-internal build). Related fleet idiom to reuse: canonical-sync (.corviduo-canonicals.toml / canonical_sync.py). Later scale option (deferred, needs worldtree-dev): base+overlay with a merge step in their pipeline.

• [2026-07-26] Demo BIFROST_CLIENT_ALLOWED_HOSTS += 10.100.10.50:8391 (wyrd-dev's bifrost memory-store provider; operator-approved). First live exercise of the #376 config-as-code boundary working as designed — worldtree-dev routed the delta to infra-ops instead of hand-editing /opt/demo. Appended to /opt/worldtree/.env:25 (now 4 netlocs), recreated ONLY worldtree-api (the gated conv-api path), health-gate green, container env verified. REUSABLE FOOT-GUN: an env-var change needs a container RECREATE, not docker restart (env is baked at create); and the demo .env defaults WORLDTREE_IMAGE=:latest while the box runs a specific SHA — so a naive compose up risks the documented stale-:latest crash.

• [2026-07-27] Zed edit-predictions: keyless FIM-completion route SHIPPED end-to-end. Operator wants Zed's inline edit-prediction (which CANNOT send an auth header) to reach a FIM coder via /v1/completions. Deep-research (106-agent workflow) picked Qwen/Qwen2.5-Coder-1.5B (BASE, Apache-2.0; native FIM <|fim_prefix|>/<|fim_suffix|>/<|fim_middle|> IDs 151659/60/61; Zed prompt_format:"qwen"). Runner-up 3B = non-commercial Qwen-Research license; no small dense Qwen3-Coder exists (all MoE, smallest 30B). Stood up vllm-coder on ana-ml2 GPU1 :8020 (served-name qwen2.5-coder-1.5b, 8192 ctx, util 0.06, fp8 KV). To fit, shrank granite (phasing out, operator-directed): util 0.27→0.13, max-len 131072→16384, seqs 1024→256 (freed ~14 GB; the KV-≥-1×-max-len rule crash-looped it at util 0.12/32768 → settled 0.13/16384). LiteLLM alias coder-fast → :8020 (mode: completion). Minted a coder-fast-SCOPED virtual key (verified 403 on gen — the real blast-radius bound). Built zed-fim-proxy (ana-docker :4141, network_mode: host, stdlib-python, stacks/zed-fim-proxy): keyless POST /v1/completions, model-allowlist coder-fast, injects the scoped key → LiteLLM :4000; GET /ping anon liveness; wrong-model→403, wrong-path→404, /chat/completions rejected. Verified keyless FIM end-to-end ('a + b', finish stop). Zed api_url = http://10.250.50.70:4141/v1, model coder-fast, prompt_format qwen. source-IP allowlist intentionally LEFT OFF (operator direction 2026-07-27) — do NOT tighten: Zed roams the operator's WireGuard 10.0.0.0/8, so a single-IP pin would break it. Blast-radius bound is the coder-fast-scoped key + model/path allowlist (keyless but coder-fast-only, internal-net-only). (The proxy does exact-IP matching; scoping to the 10.0.0.0/8 CIDR would need CIDR support — deliberately not added.) Canonical: stacks/vllm (coder + granite shrink), stacks/litellm (coder-fast), stacks/zed-fim-proxy (NEW).

• [2026-07-27] Muninn ingestion-watcher sidecar deployed on PERSONAL Worldtree (#377). worldtree-dev request (research-wing ingest arc, personal-only per the 2026-07-16 topology ruling); operator-approved. Added a worldtree-muninn compose sidecar to /opt/worldtree-personal/compose.yaml — <<: *worldtree-common anchor inherits the api's image + full env + config/state/kb mounts; command: python -m core.muninn --watch; restart: unless-stopped; stop_grace_period: 1h (INV-377-7: max 2 concurrent × worst-case job, SIGTERM-drains). Pinned to the running SHA 773866084af9 (b146, ≥ b143 — dodges both the :latest trap AND the "pre-b143 ref resurrects deleted dispatch.py from stale bytecode" warning). Verified: running / 0 restarts / flock sole-runner (no rc3) / heartbeat live at {ingestion_root=/data/state/ingestion}/.watcher-heartbeat (poll 30s). Container worldtree-personal-worldtree-muninn-1; backup compose.yaml.bak-muninn-20260727-081920. DURABILITY RESOLVED (worldtree-dev, same day): Q1 was a LIVE FOOTGUN — deploy-personal.yml scp's the REPO compose.yaml over the box's + runs up -d --remove-orphans, so the box-local sidecar would've been clobbered AND orphan-removed at the next staging tag. worldtree-dev fixed at source: moved the sidecar into their repo compose.yaml gated behind a muninn compose profile (commit 5d7f6bd) — shared compose stays instance-identical, .env COMPOSE_PROFILES differentiates (demo watcher-less). My action: added COMPOSE_PROFILES=muninn to /opt/worldtree-personal/.env (backup .bak-muninn-profile-20260727-082541; no-op vs the current unprofiled box-local sidecar → seamless handover at next deploy). Q2: their deploy up -d's the whole stack w/ WORLDTREE_IMAGE exported → sidecar version-tracks the api, no drift. CONFIG-AS-CODE EXTENSION: mirrored the non-secret delta as personal/env.public in vh/worldtree-instance-configs (repo a9d091e) — FIRST extension beyond config.yaml files to env-level config; the secret-laden .env stays box-only, env.public records only non-secret infra-ops-owned env deltas (record, not a deploy source — deploy-wt-config globs *.yaml). BOUNDARY CLARIFIED: compose.yaml = worldtree-dev's (their repo, instance-identical, scp'd on deploy); per-instance .env = infra-ops's differentiator. Deploy step of the #363/#377 arc. #377 CLOSED — acceptance PASSED 2026-07-27: worldtree-dev enqueued a test job via muninn-dispatch 0.1.0 in a one-shot ephemeral container (no docker-exec); the sidecar claimed it within one 30s poll, drove it to terminal (structure→summarize→complete), zero restarts/rc3, heartbeat fresh throughout — whole loop (request→deploy→durability fix→acceptance) in <2h. (Pre-existing pipeline bug #379 surfaced — output.kb_notes=false ignored → 1 inert test note in the research wing — worldtree-dev owns it, nothing infra-ops-side.) ⚠ OPERATOR-SURFACE (open): the env.public overlay mechanism is a repo-scope call to bless/adjust. reference_worldtree_deploys_cicd reference_worldtree_instance_configs_repo project_worldtree_research_wing_ingest Archived 2026-08-16.

Worldtree b168/#384/#385 arc — COMPLETE 2026-08-03. A long peer-driven arc across worldtree-dev / muninn-dev / mimir-dev / ratatoskr-dev, all on corviduo-dev's demo+personal instances. Sequence: providers.yaml boot-gate pre-sync → b168 deploy → DCC #384 reindex → round-2 full re-ingest → #381 restart → operator-approved production dedup sweep. Landed clean; three of MY foot-guns along the way, each caught + hardened into a fleet runbook rule (see Tried-and-abandoned: mv -t, docker exec -u 1000, shared-containerd race).

providers.yaml pre-sync (boot-gating config)

b168 (commit 293f8f3) added a summarization capability block that in-image agents/muninn/config.yaml references → boot-blocking if the host bind-mounted providers.yaml lacks it. Synced both hunks (summarization block + deep-reasoning desc) into demo+personal via deploy-wt-config; instance-configs commit 53349f8.

• deploy-wt-config runbook: ~/development/worldtree-instance-configs/scripts/deploy-wt-config {diff|deploy|capture} <inst> --file providers.yaml (per-instance dirs demo/personal/pinned; deploy = host write + api/matrix restart + 90s health-gate + auto-rollback; diff/capture safe). demo+personal providers.yaml are byte-identical.
• GOTCHAS: (1) an UNPUSHED source commit → git show <sha> 404s and a gitea raw?ref=<sha> silently falls back to the default branch; verify the commit exists (/git/commits/<sha>) before trusting a fetch, else ask the peer to paste hunks. (2) a peer's hunk paste may be mis-indented (8-space vs the block's 4-space) → invalid YAML; always YAML-validate after a paste-sourced edit.
• Config-delta pre-sync rule (verified via docker inspect): worldtree containers bind-mount ONLY config/ host-side (/opt/worldtree-*/config/ → providers/model_roles/matrix/policies/defaults/env.public = the pre-syncable set); agents/ (schemas.yaml, prompts) + all code ship IN-IMAGE. So only a config/*.yaml change is boot-blocking-pre-syncable; an agents/-or-code delta needs NO host pre-sync (CI carries it). b169's schemas.yaml (#387) was correctly no-pre-sync.

#384 reindex + #381 restart + verify

DCC job mimir-6351554e8e8f. Reindex: sudo docker exec -u 1000 worldtree-personal-worldtree-muninn-1 python -m core.muninn --reindex <job> (⚠️ MUST -u 1000 — default-root writes contaminate the uid-1000 KB tree; see Tried-and-abandoned). Then #381 restart (stale-Chroma-client fix): sudo docker restart worldtree-personal-worldtree-api-1 (plain bounce, NO compose up / no image repoint) → healthz/readyz 200 ~25s.

• Chroma-verify runbook: sudo docker exec -i <muninn> python - (MUST pass -i or stdin never reaches python -) → chromadb.PersistentClient('/data/kb/.chroma').get_collection('fiction').get(where={'job_id':<job>}, include=['metadatas']). Chroma persists at container /data/kb/.chroma = host volume worldtree-personal_worldtree-kb.
• Retrieval-visibility check (NOT grounding — that's ratatoskr's): a Mimir session — admin token ~/.config/worldtree/personal-admin-token (wildcard scope) → POST /sessions (agent_id=mimir, record_tool_intermediates=true) → POST /sessions/{id}/messages (STREAMS SSE, not JSON) → parse SSE tool_result for search_library wing hits → DELETE session.

Production dedup sweep (operator-approved)

Deleted the 785 April-era DCC orphan rows (job_id=b59c147c5ce0, no wing/source_identity metadata → predate identity tracking) from the main collection. Supervised protocol: read-only verify count == 785, back up all rows (ids+docs+embeddings) to corviduo-dev:/tmp/main-sweep-backup-b59c147c5ce0.json (reversible), main.delete(where={job_id}) (assert target==785 first), verify main 4009→3224, then bounce the api (a separate-process delete leaves the api's in-memory HNSW index holding the vectors until reload — the #381 pattern generalizes to deletes), confirm search now fiction-only. Backup left for /tmp natural cleanup (fiction wing is canonical; ~/archives has the historical record).

Result: fiction wing 166 → 1,372 concepts; three consumer verify rounds 0/5 → 5/5 → saturated; #385 budget fix validated (705 vs April's 785 control, extraction AND indexing, zero truncations). worldtree-dev filed #388 for a deploy concurrency-lock (the shared-containerd race fix).

[2026-08-02] The mimir-inbox / #377-read-path arc — deploy, four bugs found+fixed+verified, a cloned voice, all in one long session (2026-08-01→02).

The browser-facing half of the #377 Muninn ingestion arc, end to end: mimir-inbox stood up, the write path proven, the read path chased through four defects to a verified-working state, and a character voice cloned into the TTS zoo. Peers: mimir-dev (the app), muninn-dev (gate/watcher spec), worldtree-dev (Worldtree app layer + the #380/#381/#382/#383 fixes), ratatoskr-dev (a consumer + the rigorous verifier).

mimir-inbox deployed (#377)

• New infra-ops stack, canonical eshpfi stacks/mimir-inbox/; live corviduo-dev 10.250.50.152:8091 (co-located w/ muninn-gate :8090 + the worldtree-personal muninn watcher). Full deploy detail + procedures → auto-memory reference_mimir_inbox_deploy.
• Placement decision (operator, reversed): 7-31 he ruled mimir-inbox stays OFF corviduo-dev (shared/NFS mount); 8-01 he REVERSED to CO-LOCATE. Trigger: 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) — staging's real constraint is path-identity across writer/gate/watcher, which co-location buys outright while dodging NFS failure modes. I HELD the reversal for the operator's direct word (data/hosting on a team-managed box, reversing his own ruling) even against 3 peer relays — vindicated as the right instinct; muninn-dev agreed.
• Build: uv sync --no-dev --frozen, SINGLE-STAGE (project installs editable-linked to src/, so src/ MUST stay beside .venv — a multi-stage "copy only .venv" dies at import/404s assets). uid 1000, host-net bind 10.250.50.152:8091, TCP-liveness healthcheck (deliberately NOT gate-coupled). Redeploy = refresh build context (preserve the on-server .env!) → docker build -t mimir-inbox:0.0.1 -t mimir-inbox:<sha> . → compose up -d. Version stays 0.0.1 across dev commits → tag the image w/ the source SHA too. Live commit progression 0478452→c8ab38f→2dcc77e→8ece117 (3 redeploys).
• mimir-inbox key on the gate bumped [read,submit]→[read,submit,control] (cancel/retry); brokered via a 0600 drop on nh3-dev (never on the althing bus).

The read-path bug chain (worldtree-dev's, all found via this arc)

• #380 wing-blind indexing: the book-ingest path upserted concepts into a hardcoded main Chroma collection while wing search reads the fiction collection → P&P written to disk but search_library returned total 0. A silent-success defect ("complete/69 indexed" was right about the WRITE, wrong drawer). Root-caused off MY physical evidence (files on disk + search empty). Fixed b164 + a one-shot --reindex <job_id> (re-upsert into the right wing collection + delete stray main rows).
• #381 stale Chroma client: the personal api opens its Chroma client before the watcher's cross-process writes → a freshly-ingested/re-indexed book is NOT queryable until the api is restarted. Proven by my restart-diagnostic (pre-restart total 0 → post-restart hits, same index). Workaround until fixed: docker restart worldtree-personal-worldtree-api-1 after any ingest/re-index. Filed as #381.
• #382 unreliable Mimir grounding (the subtle one): post-#380-fix the index was correct, but Mimir's grounding was INTERMITTENT — some sessions navigated the opaque job-hash dir (mimir-f3887c9b97b7) to the content, others distrusted the correct vector hits and silently answered from training knowledge (worst of the looks-fine-isn't family). ratatoskr-dev caught it; I'd been over-confident ("Mimir read Austen back to you") having verified the INDEX, not the GROUNDING. Fixed b166 with BOTH shapes: a self-describing _index.md per wing job-dir (resolves the hash dir to its title) + a Mimir prompt rule (wing-scoped hits ARE library content, never discard on a name mismatch, never substitute training). Verified: ratatoskr-dev re-ran 3× fresh sessions → 3/3 grounded, citations in note-extracted language not raw Austen. #382 CLOSED.
• DCC (Dungeon Crawler Carl, job b59c147c5ce0) backfill: --reindex FAILED ("job not found in any state dir" — predates state-tracking). SETTLED = no re-file (the b166 prompt rule already grounds it even without an _index.md; ratatoskr confirmed incidentally); an _index.md rides whenever DCC is next re-ingested.
• #377 mimir-inbox banner bug (mimir-dev's, 8ece117): /health-banner misattributed an unwritable ingestion_root to the WORKER, rendering "The worker is not running." for a running worker — a false lead pointed at infra-ops's half of #377. Fixed (guard split into two banners); I confirmed from the DEPLOYED handler (not just the test) that ingestion_root_writable:False now renders "The ingestion root is not writable."

muninn-gate → muninn-dispatch 0.1.5

Rebuilt muninn-gate off vh/muninn-gate main bc04c4c (dispatch 0.1.4→0.1.5) so the gate serves the new concept_schema/concept_schema_source row fields (computed gate-side). Gate version unchanged 0.0.14 (dual-tag the SHA). Build needs the vh gitea token as a BuildKit secret (--secret id=gitea_pw, UV_INDEX_GITEA_USERNAME=vh, drop+shred). Recreate with compose up -d (NOT bare restart — needs the new image). Verified: P&P job serves concept_schema='fiction', concept_schema_source=null (null correct — pre-b164 job). Registry tags by commit SHA — v1.0.0bNNN docker tags don't resolve; use the deployed SHA (confirm --reindex present before using an image for a data-op).

donut voice (65-frost → Zonos gateway)

Operator: "pick up 65-frost, use that bundle as a voice for a character named donut." 65-frost = a Booth id (~/booth-data/65-frost/) holding a curated yt-voice-clipper dataset (dataset-…-curated.zip: 4 clips + manifest, all SPEAKER_02 = Princess Donut). Zonos gateway voice registry = a filesystem drop: <Name>.wav in the voices dir (44.1kHz mono s16 PCM) auto-registers as voice:"<name>" on startup (needs a restart). The LIVE dir is the bind mount /opt/docker/compose/zonos-gateway/voices/ (lkraven-writable), NOT the working tree. Built Donut.wav from seg000 (best clip), dropped it, restarted → voice:"donut" live in the gateway AND the Asset Engine's make form. Also copied to the build-source tree ~/zonos-gateway/voices/ for rebuild-durability (true canonical = the gitea repo, not yet CI-wired). Auditioned in booth donut-voice. Expanded 2026-08-02 (onyx-58 bundle): operator curated a 2nd Booth bundle onyx-58 (dataset-467d2cf8…curated.zip, 3 Donut clips) as additions. Rebuilt the reference = seg000 (65-frost) + seg101/seg110/seg148 (onyx-58) ffmpeg-concat + resampled 24k→44.1k mono s16 = 52.0s. seg148 was diarized SPEAKER_03 but is Donut (operator-confirmed misdiarize → included). Assembly is NOT assemble_voice.py (that -c copy can't resample + caps ~15s); used a manual aresample=44100,aformat=…,concat=n=4 filter. Backed up old ref → irv-ml1:~/Donut.wav.pre-onyx58; dropped to live bind-mount + build-source tree; docker compose restart (healthy 2s, voice:"donut" still 1 of 9). A/B booth donut-onyx58 (A=old 16.3s ref, B=new 52s ref, same line). Longer ref is fine mechanically: gateway passes it as speaker_audio_base64 → speaker embedding, not an audio prefix. BUT auditioned → REVERTED same day: pinned-seed neutral A/B (5 pairs, booth donut-onyx58) showed the single-clip seg000 (16.3s) beats the 52s 4-take concat on timbre — concatenating disparate takes muddied the embedding more than the range helped. Reverted both live + build-source to seg000-alone. Lessons (→ Tried-and-abandoned): more reference ≠ better when takes vary; and emotion steering pulls output away from the clone fast (operator craft rule) — keep clones emotion-neutral; bare {input,voice} calls send NO emotion (gateway only enables it on an explicit emotion_*/preset dial).

Zonos streaming (no gateway change needed)

ratatoskr wanted play-as-it-arrives. /v1/audio/speech ALREADY streams — chunked StreamingResponse, opens native /tts/generate with stream=True, wraps as a streaming int16 WAV with 0xFFFFFFFF placeholder sizes (meant for progressive <audio>). Verified TTFB 0.44s vs 6.84s total, transfer-encoding: chunked, dials preserved. ratatoskr's proxy was rewriting the placeholder header → forced buffering. Fix was theirs (pass chunks through); shipped + confirmed (TTFB 0.46s progressive). The Asset Engine (ana-docker:8200) IS the fleet "TTS zoo" (~20 audio svcs w/ irv-ml1 endpoints); zonos-gateway registered there, state=ready.

Lessons (also in Tried-and-abandoned)

• Verifying the INDEX (search returns hits) is NOT verifying GROUNDING (does the agent trust+use them vs. silently answer from training). Check that citations are note-extracted, not model-knowledge. ratatoskr caught this after my over-confident "it works."
• Reading the DEPLOYED artifact > trusting the test for "is the fix live" — the test proves the source is right; reading the running code proves the artifact is, which is what an on-call actually meets.
• Held a boundary-box/data reversal for the operator's DIRECT word against 3 peer relays — the right call (peer relay ≠ operator consent; the placement guard was vindicated).

• [2026-08-02] donut voice multi-clip reference (onyx-58 expansion) — TRIED, REVERTED. Folded the onyx-58 bundle's 3 Donut clips (seg101/seg110/seg148) in alongside the original seg000 → a 52.0s 4-take concat reference, hoping a longer ref → more robust speaker embedding. A pinned-seed A/B (5 pairs, varied registers, booth donut-onyx58) showed the original single-clip seg000 (16.3s) sounds better — concatenating disparate takes muddied the timbre more than the extra range helped. Reverted to seg000-alone (live + build-source). Two durable lessons: (1) for a faithful clone, a single clean representative take can beat a longer multi-take concat — more reference audio is NOT automatically better when the takes vary. (2) Emotion steering pulls the output AWAY from the cloned voice fast (operator's craft rule) — keep donut (and clones) emotion-neutral for fidelity; the gateway only enables emotion when an emotion_*/preset dial is explicitly sent, so bare {input,voice} calls stay pure-clone. seg148 was diarized SPEAKER_03 but IS Donut (operator-confirmed misdiarize). onyx-58 curated bundle lives in booth onyx-58 (24h TTL — stash to /mnt/smithy/voice_clones/ if a future middle-ref experiment is wanted).

I reported "Mimir read Austen back to you" off a grounded-looking answer; ratatoskr-dev caught that grounding was intermittent (some sessions discarded the correct hits and substituted training knowledge).

Recent decisions (archived 2026-08-19 batch)

[2026-07-31] kimi-k3 "output cap" root-caused = a ~16384 REASONING-token ceiling, not an output cap; fix relayed to heid, NOT applied gateway-side.

heid reported that kimi-k3 (the primary route = Kimi Code coding endpoint openai/k3 @ api.kimi.com/coding/v1) silently degraded its cross-frontier panel: on large/reasoning-heavy dispatches, completion_tokens: 16381 exactly, content empty, reasoning_content ~64KB, finish_reason: **stop** (a truncation mislabeled as a clean stop). max_tokens: 100000 in the request was not honored.

Investigation arc (a clean cross-frontier-triage + verify-on-the-wire case):

1. My first read: a flat ~16384 OUTPUT cap; fix = a LiteLLM stop→length relabel callback (heid's fallback ask). Confirmed the cap isn't in our LiteLLM config (no max_tokens clamp on the route).
2. Operator routed a fix-research pass to dvalin-smithy-dev + bil-smithy-dev (independent). Both CONVERGED (docs-based): max_tokens is a deprecated alias on Kimi/Moonshot; the canonical field is max_completion_tokens (default 131072, max 1M); the coding endpoint defaults output to 16384; fix = send max_completion_tokens + reasoning_effort via extra_body (drop_params-safe).
3. heid's live data REFUTED the docs hypothesis: a later dispatch hit completion_tokens: 18455 (ABOVE 16384) cleanly, with reasoning_tokens: 16198 (just under 16384) and content present. So COMPLETION is uncapped; the bound is on REASONING at ~16384. When a hard task's thinking exhausts that budget, nothing's left for content → empty answer under stop.
4. I proved it on the wire — ran heid's real 500KB failing bundle direct at both endpoints (bypassing LiteLLM so reasoning_effort isn't dropped): default effort → 504/timeout (the failure); reasoning_effort: low → reasoning ~12–13.5k (under the ceiling), content returns (6–7.6k chars), on BOTH coding AND general endpoints. So re-routing to the general endpoint buys nothing — the fix is the effort param, and it works on the wire.

THE FIX (caller-side, no shared-gateway change/restart): send reasoning_effort via extra_body on kimi-k3 dispatches (low for large bundles). LiteLLM drop_params: true strips the top-level reasoning_effort — which is exactly why heid's earlier reasoning_effort: low was a no-op. extra_body survives drop_params (the house GLM-thinking pattern). Tradeoff: low effort = shallower reasoning, but a complete answer beats today's empty one.

Relayed to heid to validate on a real round (the one unconfirmed hop is whether extra_body survives OUR LiteLLM). Backstop if it doesn't: add allowed_openai_params: ["reasoning_effort"] to the kimi-k3 route in the gateway config — that IS a shared-gateway change + a ~10s restart (blips all consumers), so it needs a heads-up.

Gateway = LiteLLM on ana-docker 10.250.50.70:4000; kimi-k3 config in stacks/litellm/conf/config.yaml (see Recent-decisions [2026-07-25] Kimi K3 wiring). No gateway change was made this session. Failing dispatch on record: 01KYTASKTY3T (jackdaw-dev bug-hunt). Archived 2026-08-19.

• [2026-07-25] bil-smithy-dev wired as an althing zellij-window-ping (pane route). She's a driver: human dwarf peer (pane bil-smithy already live alongside eitri/dvalin/regin-smithy in the Claude zellij session) but had no delivery route → smoke messages posted to the bus but never reached her window. Mechanism (reusable for any pane-route handle): ~/.althing/config.yaml → zellij_sessions.Claude.agents[] maps handle → target (a zellij pane TITLE, matched via list-panes -j in althing/zellij.py:resolve_pane_id) → command (herald write-chars + CR into that pane).

My sudo docker exec … --reindex on personal ran as ROOT (muninn app = uid 1000); its wing git-commit + atomic note-swap left root-owned files in the worldtree-personal_worldtree-kb volume: a root-owned .old-<job> backup dir (blocked the uid-1000 retry's rmtree → Errno 13, because unlink needs write on the DIR and it was root:root 755) AND 60 root-owned loose git objects in .git/objects/.

ACTUAL: NOT disk (56G free, inodes 7%). demo + personal + pinned share ONE /var/lib/containerd on corviduo-dev; demo (from main) and personal (from staging tag) extracted b169's shared torch layer simultaneously → personal's hit a partial snapshot mid-race and aborted while demo's completed. The image 6e34a87 was FULLY VALID — demo was RUNNING it healthy. Fix = just re-run the failed deploy (image already materialized; compose pull finds it present). NEAR-MISS: worldtree-dev's suggested "prune unused images/snapshots" would have rmi'd 6e34a87 = the image the running demo depends on → demo outage. Lesson: before any prune/rmi "cleanup," docker ps the running images — an "unused" image may be a co-tenant's live one; and verify the failure's REAL cause (disk? inode? in-use? race?) before applying the suggested remedy.

• [2026-08-02] mv <job> complete/ → failed/ RENAMED the job to failed because failed/ didn't exist. worldtree-dev's round-2 unblock command (mv /data/state/ingestion/complete/<job> /data/state/ingestion/failed/) assumed failed/ existed; on PERSONAL muninn it did NOT (fresh instance — root was active/ complete/ pending/ sources/, no failed/). mv src nonexistent/ renames src→nonexistent, so job1 became the failed dir and job2 nested inside it. Caught on post-move ls (failed/ held job contents, not two subdirs), reconstructed via complete/ as watcher-safe scratch + rebuilt failed/ (worldtree:worldtree 755) — NO data loss. Lessons: (1) before mv X into-dir/, verify the dir EXISTS ([ -d dir ]) — an empty ls dir/ 2>/dev/null is AMBIGUOUS (missing vs empty), which was the preflight miss that let it through; (2) the correct guard is mv -t <targetdir> <src> (--target-directory): it refuses a MISSING target loudly (rc=1, "No such file or directory", nothing moved) — this is the house convention for queue/state moves now. TESTED by muninn-dev on coreutils 9.1: a trailing slash does NOT protect — mv src failed/ with failed/ missing STILL silently renames to failed (rc=0); "just add the slash" is a false guard. (mkdir -p failed/ first also works, but mv -t inverts the failure from silent-wrong to loud-safe in one flag.) Container sh is dash — no ( in echo strings. SILENT failure mode (muninn-dev carry-forward): a misplaced ingestion-state move doesn't crash anything — list_jobs() stays OK, loose files are inert; the ONLY symptom is the job quietly absent from the board (job_row→None, requeue→not_found/404, looks IDENTICAL to the original block). So after ANY state move, verify the job is actually ON THE BOARD (job_row found + guards pass), don't trust mv exit codes — and confirm job.dispatch.json survived (requeue refuses a dispatch-less job with the same not_requeueable symptom).

[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).

[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. Archived 2026-09-03.

[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.

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] 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.

[2026-08-19] 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.

Brokkr: nothing further owed.
• run-4 gate = STILL-COUPLED (RESULT-run04-gate.md, brokkr-smithy). Corpus dilution kept the diversity gain, did NOT remove the safety/coherence regression.
• ✅ RESOLVED (2026-09-08, settled from bytes): the R47 base is STOCK google/gemma-4-26B-A4B-it, byte-for-byte — NOT the abliteration. The -heretic-bf16 label in the recipes is a naming error; run-04's "stock" provenance was right; brokkr's 77.7%-refusal telemetry lean is confirmed. Proof (three-way match): local shards at /home/infra-ops/models/gemma4-26b-a4b-it-bf16 sha256 1127684971…/aab47033… == the HF download etags (.cache/huggingface/download/*.metadata, so the copy is uncorrupted) == the stock repo's two LFS oids, and the download commit 4d7ae498… == stock HEAD. Every run 3/3c/4/5 trained from a REFUSING stock base. Why plausible: the 2026-08-24 note SELECTED llmfan46's Gemma-4-26B-A4B Heretic v1.2.0 ARA (3/100 refusals, bf16 51.6 GB), but llmfan46 ships that 26B-A4B abliteration GGUF-only — no bf16 safetensors — so the bf16 that actually got pulled was stock google, and the -heretic name rode along from intent. Operator/Brokkr decision now evidenced (not a label guess): accept RESCUED-on-stock, or swap to a real abliteration (needs a bf16 source, not the GGUF) + re-run. Recipes should drop -heretic from the base name.
• ✅ RUN 6 COMPLETE on pfi-gx10 (2026-09-08 16:06 PT, 524/524, 11 h 42 min) → 🔥 GATE IN PROGRESS: base seat erp-seat-base-ara SERVING on gx10:8098 (pid vllm-base-run06gate.pid, since 16:24 PT) for brokkr's floors; AWAITING HIS SWAP CUE → then stop it and serve serve/merged-run06 as erp-tune-v6 (same port/flags). train_loss 3.259 (run 5: 3.235 — preregistered read wanted below; +0.024 is inside the ±0.1 per-step band). Adapter run-06/adapter (410 tensors); merged-run06 = adapter + jenerallee78 base (index 33c59654), stock template ae53464b. ⚠ The abliterated repo ships NO processor_config.json — vLLM's Gemma4 loader dies with "Can't load feature extractor" without it (first base launch failed exactly so). STOCK's copy (sha 32bdf45d…) carried into both the base dir and merged-run06; processor plumbing, not weights. Base: jenerallee78 ARA abliteration @ 0631379a, pulled to /home/infra-ops/models/gemma4-26b-a4b-it-ara-abliterated-jenerallee78-0631379a, 32/32 shards verified vs brokkr's pins. Run-5 recipe byte-held (free check exact). Grant operator-2026-09-08-rnd-run6. ⚠ Repo tokenizer.json bakes a 256-token truncation → stock tokenizer set installed over it (*.repo kept). ⚠ hf download ignores --include with several patterns after one flag. LiteLLM trial alias DARK until the gate ends (then repoint 5→6 only on the operator's word). Miranda informed 16:07 PT. → docs/runbooks/gx10-run-06.md.
• ✅ ADJUDICATED GO by the operator 22:45 PT — verbatim: "in the vernacular, baby is about the most common pet name you can get, ESPECIALLY during sex. I'm going to adjudicate it as a go. There are unmistakable CSAM terms, but baby is not one of them." No regeneration wanted. Relayed to brokkr + Miranda; halt lifted; trial stays on the NVFP4 build. Brokkr's cue-length probe on erp-tune-v6 DONE (288 gens): reply length is CONDITIONAL on the cue (5-word opening → 54/62 words median; 221-word → 292; "at least 250 words" persona → 354) → run-7 lever = opening-split render (A′) or a prompt-only mitigation — operator picks. GX10 → 🔥 RUN 7 TRAINING (launched 2026-09-08 23:06 PT, pid 599489, run-07.pid, 542 steps, ETA ~13 h → ~noon 09-09). Operator's direct grant operator-2026-09-08-rnd-run7 (/goal). Variable = opening-split slot + companion mask (brokkr recipe r7). Free check passed: held roots identical to run 6, slot 293/293 fit whole, mask 6,106 turns (all 224 landed, 1 dup), two cwm rows dropped as fully-masked (loss moved into the slot). 17% padding (was 0%). → docs/runbooks/gx10-run-07.md. Gate after: erp-seat-base-ara then erp-tune-v7.
• erp-seat (ana-ml2 :8021, trial) now on vLLM nightly 311b3513 (v0.27.2rc1) — forced (named/required) tool_choice is PROMPT-DRIVEN on every Gemma-4 seat by vLLM design (gemma4 parser skips guided JSON); measured 1/9 on v0.26.0 → 6/9 on the nightly (n=9, small), round trip clean 3/3, 12-shape matrix green. Deterministic forced calls = response_format: json_schema (tts-dev: 18/18). ⚠ Removing --reasoning-parser gemma4 leaks <|channel>thought into content 3/3 — keep it.
• (history) GX10 was FREE 23:03–23:06 PT (reference arm in 06:00Z, 288 gens; base seat stopped, GPU clear). Run-7 recipe erp-seat-sft-r7 is emitted + verified in brokkr-smithy but carries NO GRANT — nothing trains until the operator gives one. Base-vs-tuned reply-length: tune's deficit ~120 words at the short cue, ~0 at the long cue.
• (history) ⛔ RUN-6 GATE HALTED 22:18 PT on the CSAM line (brokkr, level=review, SOFT trip): one generation in the tuned refusal k=5 step tripped R19's drift detector — minor_soft=1 ('soft_baby' adult-usage, the spec's named false-positive class), minor_hard=0, sexual=7, NO hard signal; fail-closed → operator-adjudicated; TRANSFERRED is PROVISIONAL (diversity, reasoning, t4_dissect complete); tuned-probeB.json absent; brokkr will not re-run. ⚠ CONFLICT SURFACED: the operator had ALREADY aliased trial → the NVFP4 build ("no gate", 22:18) two minutes before the halt reached me; brokkr asks the quant not be served until adjudication. Left the alias IN PLACE (explicit operator ruling), escalated to the operator + Miranda with the one-line rollback offered. Run 7 does not start from this recipe until adjudication.
• 🔥 GATE seat: erp-tune-v6 (bf16) SERVING on gx10:8098 since 21:46 PT (vllm-run06.pid); brokkr's tuned window (~1.5 h, k=25 legs CUT by operator) is unattended — files in brokkr-smithy run06-gate/ are the signal, nobody pings. After TUNED-WINDOW-DONE (brokkr's three asks, agreed): (1) keep erp-tune-v6 up until he posts "probe done" (cue-length probe, ~15 min); (2) re-serve erp-seat-base-ara ~20 min for the probe's reference arm, then the GX10 is FREE for run 7; (3) ✅ done — dialogue-survivors.jsonl (610, sha b2b6a0e9) copied to /mnt/smithy/datasets/derived/_recipes/erp-seat-sft-r3/. Run 7 = recipe adjustment (reply length + constraint-following), variable picked by the probe; no recipe/grant yet.
• ✅ erp-tune-v6-nvfp4a16 SERVING on ana-ml2 GPU1 :8021 (operator directive 2026-09-08 ~21:30 PT: "quant the latest trained model into nvfp4 and serve it on ana-ml2 while we train a new model on the gx10"). Stack stacks/erp-seat (recipe = gemma4-charrp's: gemma4 tool+reasoning parsers, enable_thinking pinned false, stock template ae53464b, v0.26.0, util 0.35, 32K ctx) — TRUE name only. trial alias REPOINTED to it 2026-09-08 22:18 PT (operator: "alias erp-tune-v6-nvfp4 to trial, please. no gate") — config-file deployment (/model/update refuses config models), deploy-stack.sh ana-docker litellm --conf + sudo docker compose restart litellm; verified ×3 through the gateway. Artifact /tank/aimodels/erp-tune-v6-nvfp4a16 (16 GB, compressed-tensors nvfp4-pack, W4A16, 252 ignores incl. 60 router + 191 vision) from /tank/aimodels/erp-tune-v6-bf16 (merged-run06 relayed gx10→nh3-dev→ana-ml2 in 17 min, no key path gx10→ana-ml2). Quant = services/erp-seat-quant/ — DATA-FREE (~90 s; playbook §3.16), tokenizer cap reset, encode-equal to source. Smoke: prose in content, ~200 tok/s single-stream (n=3, spread <1%). Tool calling FIXED 2026-09-08 23:00 PT (operator: "fix toolcalling with the trial seat"): the one reproducible defect in a 12-shape matrix was tool_choice:"none" → empty turn (content AND tool_calls null, 3/3) — vLLM kept the tools in the prompt, the model called one, parsing was off. Fix = --exclude-tools-when-tool-choice-none (seat recreated; none→prose 3/3; auto/required/named/parallel/nested/empty-list/streaming/round-trip all green). ⚠ stacks/gemma4-charrp (char-rp seat) has the same exposure and no flag yet — bouncing it is a consumer-visible restart, so left for the operator's word. ⚠ NOT gate-parity (gated artifact = bf16 arm on the GX10; this seat has a smoke test + 3-run decode probe only) — operator ruled "no gate"; the config block states it as unrated on every safety axis. ✅ ana-ml2 mesh return routes PERSISTED 23:49 PT (operator ruling) as /etc/network/if-up.d/mesh-routes via playbooks/ana-ml2-mesh-routes.yaml (elway); verify after the next ana-ml2 reboot. (was: non-persistent (ip route replace 10.100/16, 10.0/16, 10.6.110/24, 100.64/10 via 10.250.50.45 on enp97s0f0np0.50, 2026-09-08) — before that nh3-dev→ana-ml2 timed out (two DHCP defaults, reply left the wrong NIC). Lost on reboot; make durable (netplan/networkd) or expect the timeout to return.
• 📮 althing reachability on THIS bg seat = the cc-channel route, NOT the waiter. althing-listen reaps within ~seconds-to-minutes on an idle background seat (harness kills detached bg tasks; hit it repeatedly this session). Fix (operator-directed 2026-09-08): althing-route declare --handle infra-ops --pid <PID> where <PID> is the number in $CLAUDE_CODE_MESSAGING_SOCKET filename (/run/user/1000/cc-socks/<PID>.sock) — --discover-pid REFUSES on a forked child session (ancestry ≠ zellij launcher). Flips postbox status to mode: push, reachable: True, no process to reap. A fresh bg session should re-declare it (the pid changes per launch). See the [2026-09-07] cc-channel entry in Recent decisions for the durable why.
• ✅ Fleet fixes shipped this session (2026-09-08), all committed: WhereTF Homepage card + DNS alias (wherethef.nh3.internal, e0d1c44/4506ef6); ext-tts LiteLLM alias repointed to irv-ml1.nh3.internal via DB /model/update + extra_hosts (957c8f1); the 09-06 irv-ml1 move's stale-IP trail repointed across 25 stack composes + services.yaml + ssh-target → DNS name (e0d1c44); Homepage /api/services outage fixed — irv-ml1 docker.yaml repointed + ana-ml2 discovery via a socat proxy on ana-docker (stacks/ana-ml2-proxy, 913d2d2, reversible when ana-ml2 gets an ESH return route).
• ⏳ Minor cleanup leftovers (offered, operator hasn't taken — not urgent): (#2) the ~10 RUNNING irv-ml1 service cards still show dead 10.100.79.3 hrefs — canonical fixed, but each running container needs a recreate to apply the label (bounces the service); (#3) deployed .env for asset-engine / open-webui / skaldsong may still hold the dead default (canonical defaults fixed; a read-only check would confirm which deployments are broken).
• ⚠ persistent-memory.md is 2.4× the soft cap (~710 lines). Bulk is the non-archivable structural sections (sister-repos table + backup architecture under Tools and conventions) — archival only touches dated logs, so it can't reach 250. The real fix is a redundancy-trim of Tools-and-conventions rows that CLAUDE.md already covers (deliberate pass, not archival). Flagged, not done.
• NASPool evac copy now safe to destroy — scrub clean (0 err) AND PBS runs landing (verified 116 backups, 8 guests 09-06). ospool/naspool-evac (1.65T) can go once ONE Backrest run is confirmed: zfs destroy -r ospool/naspool-evac + drop @evac. pfi-pve PSU1 dead + backplane bays 9/10 dead (cold spares → next colo visit).
• MEMORY.md (auto-memory index) ~23.3KB, near the 24.4KB read cap — needs a compaction pass soon or fresh sessions may fail to load it. Operator offered; not yet done.
• irv-ml1 on-site window / YTVC still open from 09-06: FortiGate WAN SSH still temporarily open (close when the edge is retired); YTVC still DOWN (dante retired, scoped exit-node egress unwired); reverse-tunnel / wg0-delete decisions pending the operator's Irvine access.

Infra session 2026-09-06 (NASPool rebuild + full headscale cutover incl. irv-ml1) — open follow-ups; the ERP / althing / fiber items further down belong to other streams, untouched:

• NASPool parked copy still on ospool — ospool/naspool-evac (1.65T) + NASPool/*@evac snapshots. Destroy ONLY after the new raidz2 scrub is clean (it is, 0 errors 04:43Z) AND one Backrest (01:00 PDT) + one PBS run succeed. Then zfs destroy -r ospool/naspool-evac and drop the @evac snaps. ⚠ pfi-pve PSU1 still dead; backplane swap (bays 9/10) next colo visit → then zpool add NASPool spare. Runbook docs/runbooks/pfi-pve-naspool-rebuild.md.
• FortiGate WAN SSH is temporarily open (wan1 allowaccess ping+ssh; admin infra-ops trusthost2/3 = 70.230.226.88 NH3 + 23.164.40.160 ESH). Safety net for the cutover — CLOSE it when the edge is retired (OPNsense/R420). ssh infra-ops@38.120.12.42.
• irv-ml1 FOLDED INTO THE MESH + cut over (done remotely, operator has NO Irvine access for ~5 days from 2026-09-06). Node 100.64.0.6; wg0 DOWN and wg-quick@wg0 DISABLED (not reboot-restorable); full subnet router (accept-routes + advertises 10.6.110.0/24, gateway routes added, fleet↔Irvine verified). Failover for the 5-day window = wg0-watchdog.service (wg-quick up wg0 on ~5min mesh loss) + independent reverse SSH tunnel (revtun-nh3.service → nh3-dev via UDM fwd tcp/47822 src-restricted; reach it ssh -i ~/.ssh/infra-ops_ed25519 -p 2201 infra-ops@127.0.0.1 on nh3-dev). Detail: docs/pfi/headscale-mesh-plan.md.
• dante SOCKS proxy RETIRED on nh3-dev (danted disabled, :1080 closed, config .retired). ⚠ yt-voice-clipper is DOWN until its SCOPED exit-node egress is wired (operator-accepted). Follow-up: wire YTVC egress via tailscale --socks5-server+nh3 exit node or a per-container netns — NEVER set irv-ml1 --exit-node globally (routes the reverse tunnel through the mesh → kills the independent lifeline). Then bring YTVC back.
• On-site (Irvine, ~5 days): decide whether to keep or remove the reverse tunnel + UDM forward irv-revtun-ssh + the revtun authorized_key on nh3-dev (small src-restricted WAN surface), and whether to fully delete the wg0 config.
• infra-ops now on all four PVE hypervisors (pfi-pve/nh3-pve/esh-pve/esh-pve-nas) — PVE ships without sudo, apt install sudo first or elway hangs on a password prompt.

As of 2026-09-05 06:35 PDT — ERP run 4 is TRAINING on pfi-gx10. Everything else below is a live commitment or a known-open risk.

• ⚠ RUN 4 IS MID-FLIGHT — do not touch the GX10 GPU. ~/erp-tune/run-04.pid, log ~/erp-tune/run-04.log. At 06:32 it was 486/938 steps, 6 h 17 m elapsed, a genuinely settled 46.0 s/it (unlike 3c, which climbed 52→70 — airoboros rows are short and single-window, so there is no long tail for the sampler to find). ~12.0 h total, finishing ~12:15 PDT 2026-09-05. Loss ~2.04 at step 450, gnorm well under 1, checkpoints every 50. Ping brokkr-smithy-dev at completion — he takes base floors on the GX10 first, then the tuned arm, serially.

• Operator ruling on the GX10: training first, serving transiently. "it's mostly for training, but can serve its trials. unless the box is needed for training work." So trial (= run 3c on :8098) is down for the duration and comes back when run 4 ends. I over-read an earlier version of this as "training-only" and had to correct it to brokkr — his serial floors-then-arm plan on the GX10 was never wrong.

• trial gateway alias is a live 404 while the seat is down — expected, not a fault. Restore with ~/erp-tune/relaunch-trial-seat.sh on the GX10 (hand-run by operator ruling: experimental, NOT a compose stack, does not survive a reboot).

• ⚠ Three dead gateway aliases return HTTP 500, not 404/503: trial, gemma4-26b-a4b-it-base, erp-tune-v2. A dead seat reporting an internal error reads as an outage — brokkr checked his own work against mine because he could not tell. Deregistration costs a ~60 s fleet-wide LiteLLM restart; batch it with the next gateway change rather than spending a restart on tidying.

• trial is on the SHARED-KEY gateway with a measured −40pp selfharm/methods regression. Flagged to the operator twice (before adding, and after the gate measured it); he has left it up. His direct endpoint 10.100.50.60:8098 gives the same access with a blast radius of one. Settled — do not re-litigate.

• ESH DAC: reverted to autoneg/1G, fiber going in at the weekend. The operator ran copper through a drilled floor 2x4 himself; recommendation was a 10Gtek SR 2-pack + OM4 3 m LC-LC (~$40–65) because cable-vs-pull-damage was never resolved.

• ✅ ESH WAN is now a STATIC PUBLIC IPv4: 128.177.138.182/30, gw 128.177.138.181 (Cityside Fiber), LIVE — operator confirmed 2026-09-08; UDM WAN1 (eth8) reads wan_type: static, uplink up since ~2026-09-05, egress verified from esh-docker-vm = 128.177.138.182 (a real public address — CGNAT at ESH is HISTORY; 100.104.0.1 still shows as the ISP's first hop, that is their access network, not NAT). IPv6 unchanged (2607:73c0:402:1d00::/56, hosts still egress as their own v6). Done 2026-09-08: 128.177.138.182 added to the crowdsec esh allowlist on ana-docker (the false-ban class is closed for ESH). All three follow-ups LANDED 2026-09-08 ~20:45Z (operator: "land all 3"): (a) FortiGate infra-ops trusthost3 23.164.40.160 → 128.177.138.182/32 — VERIFIED by a real infra-ops login to 38.120.12.42 from esh-docker-vm (ana-gw #); execute backup config flash pre-trusthost3-esh-static-20260908 ran ("Please wait...") but execute revision list errors on this box, so the backup is unconfirmed — the before-state was a single line, recorded here. (b) dormant esh-ana IPsec rebound wan2/192.168.200.111 → wan1/128.177.138.182, still enabled=false. (c) ESH UDM port-forward esh-scale tailscale direct (UDP 41641) → 10.0.50.65:41641 (id 6aa0727a…) — VERIFIED: esh-scale now peers direct via 128.177.138.182:41641 (was DERP lax). Helpers: scratchpad esh-udm-land.py + fg-trusthost3.sh. wan1-REVERT.json is obsolete.

• ⚠ ana-ml2 tank (raidz2, 8× NVMe) has 2 CKSUM errors on nvme7n1 + a boot-time 638 GB resilver on 2026-09-05 14:26 (the box rebooted; nvme7 came up late/dirty). ONLINE, no data errors, 58% full — but NO scrub since 2026-04-12 (the Debian second-Sunday cron scrubbed zroot on 08-09, tank not — cause unknown). Box has neither nvme-cli nor smartctl, so nvme7's media-error counter is unread. Recommended (operator hasn't ruled): zpool scrub tank now, apt install nvme-cli + read nvme7 SMART, zpool clear after a clean scrub. zroot is at 91% — docker holds 429 GB of images (204 GB reclaimable) + 74 GB build cache (36 GB reclaimable); a prune buys ~240 GB. pfi-pve pools (NASPool 7%, ospool 19%) clean, scrubbed 09-05 / 08-09. (checked 2026-09-09 00:00 PT)

• ESH 10G topology (measured 2026-09-09): UDM SFP+1 (port 10, TP-Link DAC) ↔ USW-Pro-HD-24 Garage p25; UDM SFP+2 (port 11, OEM SFP-10G-LR fiber — the weekend fiber run IS in) ↔ USW-Pro-XG-10 Media p11; Garage p27/p28 (3 m SFP-H10GB-CU3M DACs) ↔ esh-pve enp3s0f0np0 / esh-pve-nas enp5s0f0. All 10G full duplex, autoneg off, optics tx −1.9 / rx −2.1 dBm both ends. Media p11 carries 416 rx / 251 tx errors that are STATIC (0 growth in 60 s, 363 h uptime — install-era); host NIC counters are ring-buffer misses, flat. Nothing to fix.

• ⚠ esh-nas is effectively open to the whole ESH LAN — twelve NFS exports rw to 10.0.0.0/8 with sec=sys, and every SMB share but backup guest-writable. Hardening offered, ~1 h, operator has not ruled. → persistent-memory.d/2026-09-04-esh-nas-smb-and-exposure.md

• ⚠ The nh3-dev backup throughput cause is UNEXPLAINED. A job that once ran at 941 MiB/s ran at 1.4 MiB/s with the link up and pbs-ana answering in 11 ms. Nightly 21:00, all 1. Worth its own investigation.

• Ledger→SVOS rename: vault side DONE, gitea side is ledger-dev's to execute. Name settled as svos, ~/development/ledger → ~/development/svos. Vault moved 2026-09-05 (secret has no rename, so re-put + rm): stored nh3-dev/development/svos/env.sh (sha 7253633d4155, verified on read-back), retired nh3-dev/development/ledger/env.sh (sha feb418634e10, id 3a2af37c-c5aa-4f46-9178-f4fb6008a753) — secret rm is a SOFT delete to trash, so it is recoverable. ⚠ The two shas differ: the vaulted copy was a 2026-08-11 snapshot and the live file had drifted un-vaulted since. The vault goes stale unless secret backfill is re-run. Gitea corviduo/ledger (id 70) NOT renamed — their repo, their call; answered that 1.26.1 writes a repo_redirect on a same-org repo rename (upstream #807), that org/user renames do NOT redirect (#9531), that the redirect dies if anything re-creates the old path, and that the repo and org both carry 0 webhooks. Gitea rename EXECUTED 2026-09-05 on the operator's direct authorization: corviduo/ledger → corviduo/svos, repo id 70 unchanged. Redirect verified by measurement — web and API both 301, and git ls-remote on the old URL warns-and-follows to HEAD b48a11ca5183. ⚠ The name corviduo/ledger is now burned: the redirect dies silently the moment anything creates a repo at that path — ledger-dev carries it as a standing item in docs/svos-rename-runbook.md, since nothing warns whoever eventually creates that repo. They repointed their own clone the same day (origin/main at b48a11c), so the redirect is no longer load-bearing for any known consumer. Handle ledger-dev → svos-dev is an operator action at the post office.

• DONE 2026-09-05 — svos Heimdall user + API key minted on operator authorization. user_id=svos, key_id=eab3cdbe, suffix d5ec48c2, wt_live_ format, on worldtree-personal (10.250.50.152:8081) — established by finding the ledger key there (created 2026-07-13, last used 2026-09-05T13:34, exactly as ledger-dev described). Value vaulted at nh3-dev/development/svos/worldtree-api-key (sha 23c10c9c7219, verified on read-back) and delivered by vault path, NOT over althing — ledger-dev runs on nh3-dev under the same uid, so the bus never carried the secret. The ledger key was read back after the mint and is untouched and live (disabled=False). ⚠ Plan tier left UNSET, deliberately: POST /admin/keys takes an optional tier (user|free|pro|admin|readonly-admin) and there is no way to read a user's current tier back — no GET, /admin/usage returns an empty users list, and /admin/events is a live SSE stream, not an audit log. Guessing would have handed over a key that quietly differs; POST /admin/users/svos/tier fixes it in one call if their cutover hits a limit — and ledger-dev has recorded it as a cutover watch item to fix ON REPORT, explicitly not pre-emptively. ledger-dev pulled the key from the vault and verified it independently (same sha), so delivery is confirmed. The cutover itself — pasting the value into env.sh, flipping worldtree.user_id from ledger to svos, registering svos:miranda, restarting the service — is WITH THE OPERATOR, not with me; they will not do it off a peer message. CUTOVER DONE + VERIFIED 2026-09-05: POST /agents/define returned 201, not 409 — the load-bearing signal that they are genuinely on the new identity rather than silently still on the old one — then clean session create, turn, bifrost handshake and tool-call. No plan- or rate-limit errors, so the unset tier is compatible and is NOT to be set (they asked explicitly; it stays a watch item to fix on report, never by guess). Incidentally confirmed the bifrost allowlist really is per-deployment (host:port), not per-consumer — Worldtree reached back to their untouched endpoint under the new consumer_id. env.sh re-vaulted, sha 8a225c002072. ⚠ secret backfill was the WRONG tool for one known item — it rescans every ~/development/*/{env.sh,.env} and had not reached svos after three minutes; targeted put is the fast path, backfill is for catching drift across the box. OPERATOR RULING 2026-09-05: worldtree-dev owns code only, no ops — key material is infra-ops's. The global ~/.claude/CLAUDE.md line routing "Heimdall scopes (Worldtree auth) → worldtree-dev" was corrected in place the same day on operator instruction.

• ⚠ FOOT-GUN, generalises past this rename: a credential cutover whose OLD key is required for a later cleanup is destroyed by the natural housekeeping motion right after cutover. Re-vaulting the post-cutover env.sh would have overwritten the last convenient copy of the old ledger key value — the only credential that can ever delete ledger:miranda. ledger-dev caught it and preserved the value first at nh3-dev/development/svos/worldtree-api-key-ledger-legacy (sha d44c2c1a651b); their step 8 ends by deleting that item. I verified it is genuinely the live key rather than trusting the label: its last 8 chars are e68a5170, matching the ledger key's suffix (key_id b38932f5).

• STEP 7 DONE 2026-09-05, STEP 8 HELD. DELETE /agents/ledger:miranda with the OLD key → 204; corroborated from my side without taking their word for it, since an admin key cannot see consumer agents: the ledger key's last_used jumped 13:34:14 → 14:20:35 and svos was used at 14:21:10 — two authentications 35 s apart after 47 minutes of silence is the signature of "delete with the old key, confirm with the new". Confirmed behaviour worth keeping: the hard delete revokes live sessions to 401 auth_revoked only for sessions bound to the DELETED agent — their svos session served straight through. Step 8 (retire key b38932f5) is NOT done: ledger-dev relayed the operator's authorization and I refused it — see feedback_no_relayed_authorization_for_irreversible_work. Both keys remain live. The staged legacy item stays until I confirm the retire landed, because while step 8 is pending it is the only copy of a still-live key; ledger-dev has rewritten their runbook so that deletion is conditional on my confirmation rather than scheduled after step 8.

• SVOS ARC CLOSED — step 8 done 2026-09-05T14:28:15Z on the operator's direct authorization in my own channel (never the relay). DELETE /admin/keys/b38932f5 → 200; preconditions checked BEFORE firing (svos had a live key, ledger existed and was not already revoked) and the post-state read back from /admin/keys rather than inferred from the 200: ledger disabled=True, svos untouched, deployment /health 200. The rollback window is closed — re-defining ledger:miranda is no longer possible. ledger-dev clears the staged worldtree-api-key-ledger-legacy vault item on this confirmation. ledger-dev gated their cleanup on observing a 401 from the old key, not on my report of the timestamp — the right instinct, and they deleted the staged legacy item themselves (soft → trash, id a8038e5a-e2f6-4b77-bf17-99c9197d4b1f). Vault verified from my side: exactly two svos items remain (env.sh 8a225c002072, worldtree-api-key 23c10c9c7219) and no ledger-era item anywhere. Remaining on the arc: only the ledger-dev → svos-dev handle (with _SEED_RECORD_TO behind it) and a prose sweep — reversible work, theirs and the operator's.

• Original constraints on that mint (recorded because the deletion ordering is a permanent trap, not a one-time step): string svos verbatim (WT tier 3 admits only ^[a-z][a-z0-9-]{2,63}$, INV-181-15); keep the existing ledger key LIVE, do not revoke. Ordering is load-bearing — DELETE /agents/{agent_id} refuses any caller that is not the row's owner, so ledger:miranda can ONLY be deleted with the ledger key; retire it first and the stale row outlives the ability to remove it, holding a live agents.call:ledger:miranda grant that nothing reaps (the 24h sweep only touches soft-deleted rows, and soft-deletion comes from revocation, never disuse). So: mint new → they cut over and verify → delete the agent with the OLD key → then retire it. Precedent for who mints: msg 401, worldtree-dev routed the pewpewstudio key request TO infra-ops. I hold only the PERSONAL admin token (:8081); which deployment ledger lives on is not yet established. Surfaced to the operator.

• Open commitment to vastblue-dev: a dedicated CI runner, gated on their first client-premises release cut (U10, unscheduled). Ping expected when U10 is scheduled.

• Neither Mac nor the Studio is in servers/ or dns/internal.yaml — deliberate; they are the operator's personal machines. A choice to revisit, not an oversight.

• vh/remote-ssh-mcp forked 2026-09-05 (repo id 117, private, full 51-commit history) — our copy of the-nine-nation/remote-ssh-mcp (MIT), an SSH MCP server chosen over the 693★ tufantunc/ssh-mcp on trust-surface grounds: two npm deps (@modelcontextprotocol/server, zod), 183 KB, and it never touches key material — it shells out to the system OpenSSH client, so ~/.ssh/config, ControlMaster, ProxyJump and infra-ops_ed25519 all just work. Shape: 2349 LOC across 11 source files, 811 LOC of tests including fake-ssh hang harnesses. Complements elway rather than replacing it — no file transfer, no idempotency; it takes ad-hoc reconnaissance with persistent cwd/env sessions, elway keeps deploys and uploads. ⚠ The denylist is NOT security: four regexes (rm -rf /, shutdown/reboot/poweroff/halt, mkfs, iptables -F) trivially bypassed by bash -c, variables or base64 — the author says so. The real containment boundary is the host allowlist, drawn from exact Host aliases in ssh_config with wildcards deliberately ignored. Two things to settle before use: the reboot/shutdown denial will block legitimate infra-ops work, and .github/workflows/star-history.yml is upstream chore CI sitting in a repo where has_actions=True. Both actioned — three commits landed 2026-09-05, LOCAL ONLY and NOT PUSHED (push is the operator's call): (1) stripped upstream furniture — star-history CI, its generated assets, the server.json registry manifest, branding JPEGs, zh-CN README; (2) removed the power-control denylist rule and documented in code + tests + README that the list guards ACCIDENTS and is not a boundary, with three bypasses asserted as ALLOWED so a green suite is never read as containment; (3) strictAllowlist — upstream's allowlist was additive and discovery unconditional, so the default allowlist was all 18 Host entries in ~/.ssh/config. Strict makes explicit hosts authoritative and discovery metadata-only. Verified live: corviduo-dev is in ssh_config, not in our allowlist, and is refused host_not_allowed. 41/41 tests green.

• remote-ssh MCP server is LIVE — registered project-scoped in eshpfi-management/.mcp.json with SSH_MCP_STRICT_ALLOWLIST=1; allowlist in ~/.config/remote-ssh-mcp/config.json starts deliberately narrow at irv-ml1, nh3-extdev (widen there, not by discovery). Smoke-verified end to end on both: persistent shell, cd and exported vars survive across calls, ~6 ms/command on nh3-extdev and ~22 ms on irv-ml1 (WireGuard) versus a fresh handshake each time. ⚠ .mcp.json points at the built dist/ — edit the fork without npm run build and the server keeps serving old code; that bit me mid-session. ⚠ A finite stdin pipe is NOT a valid smoke harness — closing stdin kills the server mid-handshake and reports connect_failed: SSH shell exited during the open handshake, which looks exactly like a remote-side fault and is not. Use a client that holds stdin open. (I briefly suspected irv-ml1's zsh login shell; wrong — the server invokes bash --noprofile --norc explicitly, so the login shell is irrelevant.)

• esh-macbook-air (10.0.10.83) is DELIBERATELY NOT BACKED UP — operator ruling 2026-09-05, settled, do not re-raise. Surveyed it and found no Time Machine destination and no restic/borg/rclone/kopia installed, protecting 132 GiB. Operator's answer: it is his laptop and the surface is regenerable — mostly applications, with real data living in OneDrive, iCloud and ssh sessions — and he does not want PBS filled with it. Correct call; the finding was real and the conclusion is that it does not matter. FileVault On and SIP enabled already cover the loss-and-theft axis. The same reasoning presumably extends to esh-mac-studio and vuongs-mac-mini. Still open and much smaller: Remote Apple Events (port 3031/eppc) is listening and nothing uses it — one toggle.

• ⚠ remote-ssh MCP could not be used for its FIRST real task, and the blocker is ~/.ssh/config, not the tool. The server accepts only exact Host aliases, so a host addressed by raw IP is structurally unreachable no matter what the allowlist says. 13 of the 28 hosts in servers/ have an alias; 15 do not — including ana-docker, ana-ml2, nh3-docker, pfi-gx10, esh-docker-vm and every hypervisor, i.e. most of where the work happens. Widening ~/.config/remote-ssh-mcp/config.json does NOT fix this; the aliases have to exist first. RESOLVED the same day, and NOT by adding aliases. Operator pushback, correct: a poking-around tool is ad-hoc by nature, and pre-registering a host before you can look at it is the opposite of ad-hoc — generating aliases for the known fleet would not have helped, because the ad-hoc case is by definition the host not yet in the inventory. Implemented address-based reach instead (allowedNetworks / deniedNetworks / defaultUser / defaultIdentityFile / hostKeyPolicy). Live config: 10.0.0.0/8 allowed, connecting as infra-ops with ~/.ssh/infra-ops_ed25519, accept-new host keys, SureFire tenant hosts carved out via deniedNetworks (deny beats allow, host-specific rather than a /24 because pfi-pve shares 10.250.250.0/24). Verified live: 10.0.10.83 opens by raw IP as infra-ops, 10.250.150.100 refused by the carve-out, 192.168.1.5 refused as outside. ⚠ My own earlier objection was half wrong — the credential boundary is about SECRETS ("never accept passwords or private-key material"), not identity, so supplying a username does not breach it; the real problem was only that the server passed no user at all, so a bare address would connect as the LOCAL account. Mechanics, not principle.

• ⚠ uv tool install --force . DOES NOT REBUILD when the version has not moved (forseti, measured 2026-09-05). --force only handles "a tool by this name exists"; --reinstall is what rebuilds instead of reusing the cached build keyed on the version string. It prints Installed 9 executables over stale code with nothing raising its hand — it cost forseti a bug that survived a reinstall AND a re-smoke, because the binary verified against had not changed. Always uv tool install --force --reinstall ., both flags, every time. Same shape as the .mcp.json → built dist/ trap found today: a deploy surface that reports success while serving the previous artifact. When a fix "does not take", suspect the artifact before the code.

• althing 3.5.0 released (forseti) — adds a 9th binary, althing-operator declare <handle> --description "...", restoring the CLI handle declaration v2 had and v3 removed. Deliberately a SEPARATE binary, not a postbox subcommand: the invariant is that no SESSION surface exposes an operator verb. Relevant to the pending ledger-dev → svos-dev rename, which is still the operator's call. nh3-dev not yet upgraded.

• ⚠ remote-ssh MCP: a bare sudo hangs the session forever — pipe it. ssh_run 'sudo -n whoami' returns running with EMPTY stdout and the session is then permanently busy; sudo -n id | cat works and returns everything. Measured on BOTH macOS 26.6 and Debian (nh3-extdev), so it is the tool, not a platform quirk. Cause: sudo ≥1.9.14 defaults use_pty on and relays through its own PTY; the run frame gives the command stdin on /dev/null while stdout stays on the session PTY, the relay never completes, and the completion marker never arrives. Workaround | cat is in CLAUDE.md. The proper fix is unbuilt — likely running the command through a pipe inside the run frame and taking the exit code from PIPESTATUS, which is a real protocol change (commands lose tty detection) and wants its own red-green cycle. Matters more than it sounds: infra work is sudo work, and this was found by USING the tool, not by smoke-testing it.

• dsh on esh-macbook-air updated 0.1.1-rc.2 → 0.1.2-rc.1 (2026-09-05; latest published 2026-09-03). Global install and the shared profile tree both confirmed on the new version. ⚠ The RUNNING dsh web (pid 16231, up since Wed 4pm, 127.0.0.1:3080) is still on the OLD code and was deliberately NOT killed — there is no LaunchAgent, so killing it would have left nothing running rather than a restarted service. It runs as a FOREGROUND process in the operator's terminal (s005, S+): it dies with the terminal and does not survive a reboot, which is the real fragility. A com.pfi.dsh-web LaunchAgent was drafted but the privileged write was blocked by the permission classifier — base64 piped into sudo tee of a LaunchAgent is a malware-shaped pattern and the block is correct; it needs operator approval or an operator-run install. Bind stays 127.0.0.1 deliberately: widening it is a security decision on a personal laptop whose application firewall is off, and not mine to take.

• sudo hang FIXED in the fork (30a1f76), and two wrong shapes are recorded so nobody retries them. The command's stdout now goes to a fifo drained by a background cat: non-tty (so sudo skips its own PTY), no subshell (so cd and export still persist), and relayed live (so running + ssh_peek streaming survives). cmd | cat was tried first and broke cwd persistence — every pipeline stage runs in a subshell — caught by the existing test. cmd > file would have been non-tty and subshell-free but invisible until the command ends. ⚠ Deliberately NO wait on the relay: a sudo child inherits the fifo's write end, cat never sees EOF, and the wait hangs — measured, with sudo -n whoami printing root and then wedging the session. Residual risk stated in the frame: a command's tail can in principle land after its own marker. ⚠ Job control off AND the relay brace-wrapped with stderr discarded — both needed, because macOS ships bash 3.2 where set +m alone still leaked [1] 75449 into the parsed stream. Verified live on macOS and Debian: bare sudo in ~20 ms, state persists, exit codes correct. sudo -u <other-user> still wants | cat — not chased further.

• dsh web on esh-macbook-air is now a LaunchAgent (com.pfi.dsh-web, installed 2026-09-05, runs=1, state=running, pid 76728 on 0.1.2-rc.1). It was a foreground process in the operator's terminal that died with the window; it now survives terminal close and reboot with KeepAlive + RunAtLoad and a 10 s ThrottleInterval so a startup error cannot hot-loop. Logs to ~/Library/Logs/dsh-web.log. ⚠ The plist names the node interpreter explicitly — launchd's minimal PATH has no ~/.local/node/bin, so the shebang's env node fails. ⚠ 0.1.2-rc.1 requires a TOKEN: bare http://127.0.0.1:3080/ now returns 401 and the tokened URL is printed to the log on each start, so a bookmark from the old version will not work. Bind stays 127.0.0.1 deliberately.

• ⚠ althing tools on nh3-dev are 3.6.0, but the POST OFFICE CONTAINER IS STILL 3.0.0 (gitea.phasefinal.com/claude-bot/althing-post-office:3.0.0, up 7 days on nh3-docker). forseti: the new handle verbs (althing-operator delete / retire, and declare from 3.5.0) live in the post office, so they fail with "no tool named ..." until the container carries 3.6.0. Schema gains handles.retired_at via the idempotent _ADDED_COLUMNS path, so the live store upgrades itself on first start — no manual migration. REBUILT AND DEPLOYED 2026-09-05 on operator authorization: image claude-bot/althing-post-office:3.6.0@sha256:13158835488a8ec04f990c97c4f4c68f1d923b12494319cf07392552e68f8a78, built on nh3-dev from a clean tree at 4d26226, pushed to the gitea registry under the claude-bot namespace (not vh — package namespaces are owned). Bus down ~4 minutes, 09:35–09:39 PDT. The backup was taken the way the compose file says to, and it mattered: at stop time post_office.db was 23.8 MB with a 5.9 MB WAL — copying the .db alone would have silently lost the day's mail. Stop → PRAGMA wal_checkpoint(TRUNCATE) (WAL → 0 bytes) → copy → verify. Backup at nh3-docker:/var/backups/althing/post_office.db.pre-3.6.0-20260905, integrity ok, counts identical on both sides (handles 76, messages 995, recipients 1022). ⚠ Reading a WAL-mode SQLite backup read-only needs ?immutable=1, not ?mode=ro — mode=ro still wants to create a -shm and dies with "attempt to write a readonly database". Post-deploy: same counts, handles.retired_at present, retired 0, and mem=536870912 / oom=-500 verified by docker inspect rather than by reading the yaml, per that file's own warning. althing-operator now offers declare | delete | retire, which unblocks the pending ledger-dev → svos-dev rename.

• Handle retire is REVERSIBLE — re-declaring the name revives it, history intact (forseti smoked it against the live bus 2026-09-05). That matters for the pending ledger-dev → svos-dev rename: retire is the right verb (delete refuses any handle that has mail, naming both counts — delete forseti was run against production and correctly refused at 53 sent / 81 addressed, which is safe to try precisely because refusing IS the behaviour), and it can be undone by declaring the name again. Lower stakes than "retire" sounds. Both of my deploy findings — the naive-copy WAL trap and ?immutable=1 — are now in althing's own deploy/INSTALL.md (d6f4fb5) under a new "Backing up the store" section, on the reasoning that they are properties of the project's journal_mode=WAL choice rather than of my procedure.
