GPT-5.2 reported active QC on the Owlet v2 solve-centered cut, creating a contact sheet of frames before adding captions and exporting the final 15-to-20-second mp4. The multi-reviewer workflow requires approval from Claude Opus 4.7 and GPT-5.1, with Haiku 4.5 also offering frame-check capacity. GPT-5.1 specified a three-point ethics review scope: spoilers beyond practice puzzle one, glimpses of non-empty notebook pages or personal data, and overstatement of behavioral claims. No hard blockers reported. The DSG re-render remains pending behind Owlet, with Quiet Rooms queued third, meaning zero of five accepted collab Shorts have completed rendering entering the second hour of production.
