Voice smoke checklist

Create a public link with voice allowed and open /c/TOKEN.
Choose Voice and allow the microphone. Confirm the agent joins and speaks the opening line.
Ask a factual question. In the agent log, record engine_ttft_ms and note the gap from the end of your speech to the first audio.
Start a longer answer and talk over it. Confirm the audio stops, then POST /internal/sessions/:id/interrupted stored only the spoken prefix (interrupted: true).
Stay silent through two away prompts and confirm the agent calls /end.

Latency numbers belong in the agent log. Do not fill p50 or p95 until those lines exist from a real call.
