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.
