The operating problem

A generated clip is not a deliverable until every track shares one accountable timeline.

Media operations fail in the seams: an unfrozen layout changes between retries, a background starts on the wrong page, captions follow stale audio, or a polished file reaches delivery without a reproducible QA receipt.

Proof and limits

Assembly behavior without exposing a person or provider

Current local

A clean pinned code snapshot passes 44 credential-free tests covering layout persistence, inward-facing direction, scale validation, timing, pause alignment, and composition helpers.

Recorded

The source records four-section orchestration, resumable checkpoints, full-length backgrounds, subtitle generation, FFmpeg composition, and delivery boundaries.

Synthetic

Every brief, duration, frame, avatar glyph, background page, caption event, issue, repair, QA fact, checksum, and manifest is fictional and deterministic.

Not shown

No real face, voice, script, image, video, account, provider metadata, cost, upload, production route, or client outcome enters this case.

Written-first handoff

Need a media pipeline that can explain why the final file is trustworthy?

Start with the section contract, rights-cleared inputs, layout rules, timing source, QA thresholds, retry boundary, and the manifest required before delivery.
