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.
Three changes prepping infra for asset_engine's orchestration feature
(SSH-driven bring-up / bring-down of irv-ml1 inference services with
per-device VRAM gating, contract in vh/asset-engine commit 5a36f8c):
1. asset-engine compose + .env.example + playbook gain a read-only
bind-mount for /app/runtime/ssh — the dedicated ed25519 keypair
(generated on ana-docker, not in the repo) plus a pinned known_hosts
for irv-ml1's host fingerprint. Env vars SSH_KEY_PATH and
SSH_KNOWN_HOSTS are exposed for the app to consume.
2. docs/asset-engine/services.yaml gains a `lifecycle: { stack, vram_gb,
gpu_device_id }` block on each of 12 orchestratable irv-ml1 services
(kokoro, chatterbox, index-tts, qwen3-tts, cosyvoice, fish-s2,
kyutai-tts, vibevoice, voxtral, parakeet, stable-audio-open, ace-step).
VRAM numbers are estimates from model footprint at fp16 — tune from
real nvidia-smi measurements once the gate is live. comfyui and
kokoro-captioned are deliberately excluded (variable-VRAM and
shared-container respectively).
3. servers/irv-ml1/README.md docker-stacks table now lists all 13
inference stacks (was only dockge + agents + comfyui) with port +
GPU pinning columns.
Pubkey deployed to ~lkraven/.ssh/authorized_keys on irv-ml1;
end-to-end SSH from ana-docker → irv-ml1 verified with strict
host-key checking.
New stack mirroring PFI convention (stacks/comfyui/) using
mmartial/comfyui-nvidia-docker:ubuntu24_cuda12.8-20260312. Both GPUs
exposed, pinned to CUDA 12.8 to match the host's 570.x driver and the
native cuda-toolkit already in place.
Layout — single tree under /worktank/comfyui/ (462G dedicated, 1%
used pre-deploy):
- basedir/ → /basedir user state (models, workflows, custom_nodes,
input, output); owned 1000:1000 so external
tools can edit workflow JSON directly.
- run/ → /comfy/mnt ComfyUI source + venv + pip cache (~7.8G
after bootstrap). Bind mount instead of
named volume — the image refuses to chown
mounted paths at startup, so keeping this
lkraven-owned avoids the sudo dance.
servers/irv-ml1/README.md refreshed: Docker upgraded to 29.4.1 with
traefik-net in place; dockge + beszel-agent + dozzle-agent already
present; /storetank dropped 92% → 64%; restic coverage to
rest-server-nh3 is operational (not "currently none" as prior text).
