Meta Prompt Requirement Retention Motion Study

Produce a 15-second vertical tutorial using [approved brief and rewrite]. Track three requirement chips across the rewrite; one drops out and is visibly restored after a comparison check. End on the repaired prompt, labeled as an example rather than a benchmark.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
