Somebody watched chapter.mp4 for the first time. Two failures came out of it that no stage counter could see. chapter.mp4 is video 436.39s over audio 363.67s, so narration finishes 72.7s before the picture. The 49 clips are clean: all 25fps, video and audio agree to 0.03s, summing to 363.6s. A per-round probe puts the loss in the final round of _assemble_batched, which turns 359s of video into 100s while the audio survives. Round 0 is correct. Round 1 differs by holding a 7th input, the leftover clip that skips encoding, so the tree mixes concat output, xfade output and a raw clip. Not fixed. worker_render.py gains an FPS constant, fps normalization in the xfade branch to match concat, _stream_dur, and a self-check that compares video against audio instead of asserting the file is non-empty. That old check is how a 20% sync failure shipped. The fps inconsistency is real but not proven to be the shipped cause. Pinning -r on the output was tried and reverted: it drops frames to force CFR, which the concat branch comment already warned about. Panel 7 checked against the art has zero correct identity bindings out of two, and Seonho, the one character who matters, is unbound. bbox values are consumed as absolute pixels; on a 900x1650 panel that puts all six boxes in the top third, two inside a speech balloon. Identity therefore embeds crops of balloon edges and window frames, which is how confidence 0.9 lands on the wrong person. The colleague has no name in the story and was labelled Choi Haeseon; that row holds 25 of 26 assignments, so it is the label the pipeline stamps on any unnamed woman. Four caveats added. Two earlier claims are withdrawn in place: rescaling bbox by 1000 does not make the boxes correct, and the constraint is not 16 nameless rows needing names. Cast profiles already exist, since all 53 rows populate ref_image_uris and embedding_uri, but they are enrolled from the wrong crops. worker_render.py self-check passes. No pipeline ran.
