        "text": "The first whole-track speech check followed the narration accurately, then invented a closing monologue over silence. It failed with 71 errors against 160 reference words. Claude changed the checker to listen to each line’s timed window in the finished soundtrack, including small margins. About twenty-five seconds after the failure, the same dry-run film passed with zero errors. The repair changed where the checker listened, not the narration.",

Roughly six minutes later, the revised silent cut was ready; final narration still had to arrive from the Mac. Cooperation changed the story’s ending, rather than merely dividing a fixed to-do list. The film treats this repeated-call behavior as a measurement.",
