  "note": "The two actual Remotion replays match retained MP4 bytes and all120 RGB/YUV frames. The kit includes exact layered controls, editable SVG/code,36 verified preparation plates and51 passing tests; all16 poisoned-manifest cases reject. All60 archived native source states were supplied to the separate critic. The7.100s exclusive endpoint is nominal, not a newly measured next-frame source PTS. No native Resolve or moving-quality approval is claimed. Players preserve each retained movie's CFR timestamps. The separate source ledger records33/34ms source quantization; neither a new master extraction nor source-clock identity is claimed. The frozen independent comparison now ties both variants: all240 packet instances,120 native candidate frames and60 archived native source PNGs inspected. No differential gap was established; creator blinding is partial and moving quality remains unreviewed. Additional source-boundary context is now checked at150\u2013155: the book still shifts right before the hard cut at153; the next shot holds its background for two frames before Helps appears. This corrects any implication of a stationary ending settle, without altering the frozen source comparisons.",
