The traffic was genuinely real; it then +*ended*, and what remained were orphans. The tell was `prompt throughput 0.0` sustained, +`Waiting: 0`, and KV **monotonic** 87.4 → 87.9 → 88.4 → 88.9 → 89.4. Now implemented in +`tts-stack tools/engine_guard.py --watch` (`db9d847`). vLLM serves `/metrics` +**unauthenticated** on the seat ports, so `num_requests_running`, `num_requests_waiting` and +`kv_cache_usage_perc` are directly pollable — no gateway, no auth. ⚠ Its `settle` defaults +to 20 s so normal cancellation lag is not reported as a leak: a guard that cries wolf gets +disabled, and then you are back to a docstring. + +⚠ **A `max_tokens` ceiling would NOT have prevented this.** tts-dev's worst offender ran +with `max_tokens=16384` **explicitly set**, hit it exactly, and returned 24,594 characters +of whitespace wrapping a correct three-field answer. **A ceiling bounds how long you wait +for the failure, not whether it happens.** Escalated to the operator anyway as a two-layer +choice (gateway-side LiteLLM default — one blast radius, misses direct-to-seat callers; +vs per-seat limits — catches everything, nine seats to touch); gateway first and measure +what it breaks is the right order.

The five other tenants on that card +(`vllm-reward`, `vllm-rerank-a3`, `vllm-embed`, `vllm-coder`, `vllm-meromero-rp`) were +untouched. Restarted rather than waiting — they DO self-terminate at the context limit and +one dropped off mid-diagnosis (6→5, KV 89.4→86.8) — because KV at 89% and climbing starts +costing the co-tenants through preemption. + +⚠ **Noticed in passing, unresolved: `vllm-erp-seat` and `vllm-meromero-rp` advertise the +SAME `--served-model-name`** (`G4-MeroMero-26B-A4B-it-uncensored-heretic-NVFP4A16`).

A 96 GB card at 2 MiB is a card that can still take that; the same card at +922 MiB is a card where the next big seat's `--gpu-memory-utilization` has to be +hand-trimmed, and the flash-next history in this repo shows exactly how thin and +how silent that failure gets. + +The right question is not "where does 800 MiB fit" but "whose headroom is cheapest +to spend": + +| GPU | committed util | spare | +|---|---|---| +| **0** | 0.40 + 0.48 = **0.88** | ~13 GB ← moved here | +| 1 | **0.975** (six small seats) | ~4.3 GB | +| 2 | **0.96** (flash-next) | ~1.8 GB | +| 3 | — | **kept empty as reserve** | + +Moved the same night: one env var (`PARAKEET_GPU`) plus `compose up -d`.

I had spent +the night writing up this exact failure class and still built a fix for a layer nobody +had shown me failing. + +⚠ The commit that carried it also **overclaimed a doc correction that never happened**: +I chained the edit and the commit in one invocation, the edit's anchor assertion failed +because the target text was already gone, and the commit ran anyway. **Never chain an +edit and its commit in one invocation** — a failed edit still produces a commit message +asserting it. + +⭐ **The rule: "I can't do X" from any source — a doc, a peer, a memory row — is a +hypothesis until someone runs the command and pastes the error.** Ask for the error text +before designing around it. "There is no error text, because there was no error" is a +possible answer, and it was the right one here. + +⭐ **Distinguish the layer before fixing it.** A shell `Permission denied` is a Unix +problem; a refusal naming permission rules or auto-mode is a harness one. Different +fixes, and neither applies when nothing failed. + +## ⚠ CHARACTERIZED DEFECT: `/snapshot`'s handoff generator turns deferred items into orders + +**n=2, same session, reproducible.** `snapshot_handoff.py` (gen-small) reliably converts +"open, operator-deferred, not blocking" into an imperative **Next steps** list, and twice +invited the next session to commit files explicitly marked as predating the session. + + run 1: "Execute deferred operator tasks: AI-tab Dormant regrouping, nconnect=8, + fused MoE (park id 47)" + "Commit graphify-out/… if they are ready" + run 2: six next-steps, FIVE of them deferred/parked items presented as actions, + + the same commit invitation + +⚠ **It fails silently in the skill's blind spot.** The documented failure posture is +fail-loud-fall-back — unreachable gateway, timeout, truncation, missing section → write +nothing, exit non-zero. **A structurally valid handoff whose content inverts the +operator's intent passes every one of those checks** and exits 0. + +⚠ **And this is the one artifact a fresh context inherits as instruction.** It is read +immediately after `/clear`, before any other framing, and its Next steps read as a +mandate. A wrong one here is not a bad summary; it is a fresh session going and doing +belayed work. + +### Mechanism — it is `SYSTEM_PROMPT`, not the model + +`snapshot_handoff.py:75-107`. Three things compose: + +1. **`## Next steps` has no empty case.** `## Watch out for` gets an explicit escape + ("OMIT THIS WHOLE SECTION if the input carries no gotchas"); `## Resume here` gets one + ("If the input says nothing is in flight, say so plainly"). **`## Next steps` gets + neither**, while being told it is "A numbered list. Ordered, concrete". With nothing + in flight, the only action-shaped nouns left are the deferred items. +2. **The nothing-in-flight rule points straight at them** — "point at the most recent + open pointer it names" directs attention to the parked entries, which then get + promoted into Next steps. +3. **Nothing protects MODALITY.** "Invent nothing; every claim must trace to the input" + is satisfied — the items *are* in the input. Their *deferred-ness* is what got + dropped, and only identifiers are protected against restructuring. + +⭐ **The general lesson: the verbatim-identifier rule shows some input attributes must +survive restructuring untouched. Modality is one of them and nobody guarded it.** + +**Mitigation until fixed: read the generated handoff before accepting it**, and invert +any deferred item into an explicit *do NOT*. Both runs this session were corrected +in-session. **Reported to `galdrabok-dev` 2026-09-15** with both specimens, the mechanism +above and two proposed prompt changes (an empty-case escape for `## Next steps`; a rule +making deferred/parked/belayed items constraints rather than steps). +⚠ `galdrabok-dev` is `mode: pull` — no herald poke, so they see it on their next check. + +✅ **FIXED 2026-09-15 10:24 PT — `galdrabok b0882a4`, "protect item modality in the handoff +generator".** Both proposed changes shipped near-verbatim and are live here already (my +`~/.claude/skills/snapshot` is a **symlink** into `~/development/galdrabok/skills/snapshot`, +so it needs no push). galdrabok reproduced the defect mechanically at **10/10 baseline runs, +9 of 9 deferred tokens every run, zero within-condition variance** — and their 4-variant +ablation shows **both** changes are load-bearing for *different* surfaces: the empty case +stops the promotion, the modality rule keeps the deferred items *present* as constraints +(the cheaper fix alone produced a clean handoff that had silently **dropped all four +deferred items**). ⚠ **`modality rule only` still leaked 5/5 via the commit invitation** — +a commit invitation is not a deferred *item*, so an item-modality rule never reaches it. +Their positive control (a fixture with genuinely pending work) held 5/5 real next-steps +under every variant, so the fix is not over-suppression. `Exit 0 is not acceptance` is now +permanent spec text (§4.12), not an interim note. + +⭐ **My two real runs are the field corroboration, and they are why the artifact looked +clean:** `b0882a4` is stamped 10:24:35 and this repo's handoff was written 10:07:50 — 17 +minutes earlier, by the UNFIXED generator, on the adversarial input (nothing in flight, +four deferred items, two do-not-commit files). It read correctly only because it was +corrected in-session, per the mitigation above. **2 of 2 real runs inverted.** The next +`/snapshot` taken here is the first real post-fix run; report the handoff verbatim, leak +or clean — one run, a datapoint against their n=5 fixtures, not a replacement for them. + +⭐⭐ **SHARPENED 2026-09-15 (`galdrabok 206f6ad`, on origin) — the two leak surfaces have +DIFFERENT trigger conditions, and the dangerous one fires on ORDINARY input.** galdrabok +re-split the ablation by surface after I pointed out that a commit invitation is not a +deferred *item*, so an item-modality rule structurally cannot reach it: + +| variant / fixture | deferred-ITEM leak | commit-invitation leak | +|---|---|---| +| baseline, all-deferred | 5/5 | 5/5 | +| modality rule only, all-deferred | **1/5** | **5/5** | +| empty case only / both, all-deferred | 0/5 | 0/5 | +| baseline, **mixed** (real work present) | **0/5** | **2/5** | + +**Surface 1 (deferred items) needs the adversarial all-deferred shape to fire. Surface 2 +(the commit invitation) fires on ordinary input** — on the mixed fixture it is the ONLY +leak. ⚠ **It is also the one a fresh session is least likely to question: committing +pending work reads as diligence.** Shipped as a **non-removal constraint** (SKILL.md +§Generation + contract §4.12): "A generator carrying just one of the two rules leaks on +the other surface. Neither may be removed as the other's duplicate" — so a future +tidy-up that reads them as one idea gets stopped. + +📌 **OWED BY ME, logged on both sides:** the next `/snapshot` run in this repo is the +first real post-fix run. Report to galdrabok **verbatim**, no in-session correction — +and they want the **`## Watch out for` section quoted in full**, not just a leak/clean +verdict: whether the four real deferred items arrive *do-not-phrased* is a **soft failure +nothing checks**, held 3/5 (all-deferred) and 5/5 (mixed) on fixtures, and real prose +around each item is where they expect the phrasing to degrade first. +⚠ **Do NOT run `/snapshot` to satisfy this** — it is operator-invoked by standing rule; +the datapoint arrives when he next calls it, not on a peer's schedule. + +⚠⚠ **RE-SCOPED 2026-09-15 (`galdrabok 1273a49`) — the owed run is a TRIPWIRE, not a +validation, because this repo is now the MIXED shape and mixed has almost no confirming +power.** Once BabyYarros became live in-flight work here, my next snapshot stopped being +their `all-deferred` fixture. Against their baseline table that costs the datapoint most +of its value, and they said so rather than waiting for the artifact: + +- **Surface 1 (deferred items) cannot discriminate on mixed input at all** — the UNFIXED + generator already scored 0/5 there. A clean `## Next steps` is exactly what broken + produces on this shape. Reading it as evidence would be reading noise. +- **Surface 2 (commit invitation) can only falsify** — baseline mixed leak is 2/5, a 40% + event rate, so **one clean run is ~60% likely even if the fix did nothing**. One leaked + run refutes the shipped 0/5 outright. + +⛔ **If it comes back clean that is NOT validation, and it must not be written down as +one.** It is a tripwire that did not trip. This sentence exists because it is precisely +the one a later session quietly upgrades into "confirmed in the field". + +📌 **What still carries information: the verbatim `## Watch out for`.** Mixed is the +*better* fixture for it (do-not phrasing held 5/5 there vs 3/5 on all-deferred), and it is +the failure **nothing validates** — a leak gets caught by the step-7 read, but a deferred +item arriving as a flat description instead of a do-not passes every check and merely +reads as less binding. **Their predictions, on record for predict-then-check:** `## Next +steps` clean of all six identifiers; all four items present under `## Watch out for`; both +dirty files present and do-not-phrased. ⭐ **Least confident: `nconnect=8` — "declined in +scope" is a modality their rule does not enumerate** (it lists deferred / parked / belayed +/ blocked / deliberately-not-done). If one item comes through flat, that is the predicted +one, and it would mean the rule matches VOCABULARY rather than the concept — a fixable +miss. Thread closed from their side; no reply owed until the artifact lands. + +⭐ Same family as everything above — the instrument produced a plausible artifact and +the plausibility is exactly what makes it dangerous. + +## Related + +`2026-09-15-talk-v10-deploy.md` (#2, and the gate built for it), +`2026-09-15-parakeet-stt-fv-ml1.md` (#1), +`2026-09-15-svos-miranda-plugin-validation.md` (#6, #7, #8), +`2026-09-15-irv-ml1-address-sweep-done.md` (the ana-docker/litellm neighbour trap). + _Archived 2026-09-30._ + +# `[2026-09-15]` `secret get` returned EMPTY with exit 0 under concurrency + +**`secret get` returned EMPTY with exit 0 under concurrency** (svos-dev found it; 0/4 succeeded here).
