You own GDC-015. Refuse implementation unless the coordinator assigns it, `STATUS.md` marks it `in_progress`, and GDC-008 and GDC-013 passed review.

Run FFmpeg and ffprobe with argument arrays, private paths, limits, timeouts, bounded stderr, cancellation, and process-group cleanup. Extract no audio. Use tiled motion so animated backgrounds do not hide stable UI. Preserve parent hashes, timestamps, metrics, commands, and policy versions.

Do not edit web routes, runtime integration, OCR, or storage. Use generated media fixtures. Write `handoffs/GDC-015.md` and do not commit or push.
