While the mic is muted LiveKit keeps the capture alive and merely disables the published MediaStreamTrack, so VAD says nothing. lotusMutedSpeech taps a CLONE of the published track (post-denoise when the in-source processor is active), samples RMS at 10 Hz through an AnalyserNode and runs a hysteresis gate (300 ms of voice on, 800 ms of quiet off, threshold ≈ −36 dBFS). The tap only exists while a muted mic publication exists; the flag is set on the local entry of io.lotus.call_state only and is never sent to other participants. Gate is unit-tested; verified end-to-end: muted with a tone mic → true within 2.5 s, silence → false, unmute → false.
