Abort Cleanup Lifecycle Animation

Create a 15-second diagram animation from [verified event sequence]. Show a pending read, a cancellation event and owned cleanup in the documented order. Maintain one token per resource, removing it only when released. Label it as an illustration; do not imply a test or live trace was executed.

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.
