memory: speaches ASR live on irv-ml1 — and no_speech_prob is a weak gate

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

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

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

+- **🟢 SPEACHES ASR — LIVE on irv-ml1 A6000 :8204 (2026-08-21, operator-approved).** OpenAI-compatible faster-whisper for **Eyra** (meeting recorder, `eyra-dev`). `Systran/faster-whisper-large-v3` + `Systran/faster-distil-whisper-large-v3`, fp16, both resident (`STT_MODEL_TTL=-1`), ~5.9 GB VRAM / 20 GB still free. **Deliberately co-exists with `parakeet` (:8765)** — parakeet is a TDT/transducer returning bare `{"text":…}` with **no `no_speech_prob` concept**, so it structurally cannot serve this consumer. **★ THE MEASURED FINDING IS WORTH MORE THAN THE DEPLOY: `no_speech_prob` ALONE IS A WEAK HALLUCINATION GATE.** Silence and pink room tone both produced the classic Whisper `"Thank you."` hallucination while `no_speech_prob` stayed **under 0.11** — a conventional `>0.6` threshold passes both through. `avg_logprob` separates ~6× better (−0.114 speech vs −0.650/−0.724 non-speech); `compression_ratio` 1.141 vs 0.556. **Consumers must gate on a composite.** (Synthetic inputs — shape of the separation, not calibration constants.) **VAD pinned OFF** (`_UNSTABLE_VAD_FILTER=False`) at consumer request — they VAD-gate upstream; consequence is the service will transcribe silence and does not defend itself. **★ IMAGE PINNED BY DIGEST, not `:latest-cuda`** — the VAD flag is an upstream-declared *unstable* var name, so a floating bump could rename it, restore VAD, and move gate semantics with **no error and no log line**; bumping = deliberate + re-run the checks. ⚠ Two gotchas: `PRELOAD_MODELS` **does not download** (only loads already-cached — use `POST /v1/models/{id}`), and the bind-mounted cache needs a `hub/` subdir or **every** `/v1/models` 500s `CacheNotFound` **while `/health` still returns 200**. ⚠ docker `device_ids: ["1"]` = A6000 (native CUDA inverts this — sees A6000 as `cuda:0`). ⏳ **NOT DONE by design: no LiteLLM gateway alias** — agreed sequencing was direct-first; adding it means editing the shared gateway + re-running fidelity. ⏳ Eyra's **diarization workload** (GPU pyannote, gated weights, own HF token) is a **future VRAM claim on this same A6000** — arrives at their diarize milestone.

 - **🟢 FLEET `.internal` DNS — LIVE 2026-08-19.** `<host>.<site>.internal`, sites `ana`/`esh`/`nh3`. `dns/internal.yaml` is the source of truth; `scripts/dns-sync.py` reconciles the three AdGuard resolvers (diff → prompt → apply, idempotent). 42 names resolving from all three sites. **Colo got its first resolver ever** (`stacks/adguard-ana/`, API on **8053** not 8080, no blocklists by design) — before this, ana-docker resolved straight against `1.1.1.1`. Auth = a dedicated `infra-ops` AdGuard user, password vaulted `nh3-dev/adguard-infra-ops-password`. **⏳ TWO OPEN, both operator's to schedule:** (a) colo hosts still point at `1.1.1.1` so they do not yet *use* the new resolver — repointing a site's DNS is a separate change; (b) the static-v6 convention (each server at its site's `/64` with low bits echoing the v4 octet, `esh-docker-vm` → `…::45`) is **proposed, not ruled on**. The `v6:` column is empty and correct — no fleet host has a global v6 address yet. → `persistent-memory.d/2026-08-19-fleet-internal-dns.md`
 
 - **🟢 WATERLAND STUDIO — containerised + live, irv-ml1:8410.** Displaced a bare `nohup` (PID 1283383). Warm 256²+anim render **6.1s**, beating the 7.4s bare-metal figure. `claude-bot` now has **read** on `vh/waterland` (operator-granted); token on irv-ml1 root-owned 0600, repo-scoped helper, nothing in `.git/config`. **✅ All three upstream findings fixed and DEPLOYED at `b72425b`** (one `update.sh` run, 2026-08-19): PR #5 declared the CUDA headers and took `uv` out of the render path; PR #6 (operator-green-lit) added the startup rehydrate that fixes the unbounded job-store growth. Verified after: `/api/jobs` **1 → 16** against 16 dirs on disk — API and volume agree for the first time — nothing wrongly reclaimed (16 &lt; `RETAIN=40`), healthy on `backend: cupy`, warm render intact. The image **keeps** its `[ctk]` install (+0.3s, now a no-op audit) and `UV_NO_SYNC`/`UV_OFFLINE` as defence-in-depth. Thread closed by both sides. → `persistent-memory.d/2026-08-19-waterland-studio-containerised.md`
