Render QA And Surgical Changes

Use this skill when the video is nearly done or already approved and changes must be controlled.

Surgical Edit Rules

• Patch source artifacts, not the final MP4, when source scenes and assembly scripts exist.
• Re-render only affected scene(s).
• Rebuild the final assembly from the current approved timeline.
• Do not redesign, retime, or re-sync unrelated sections.
• Search for duplicated/carryover frames before declaring done.
• Extract proof frames at exact timestamps requested by the user.

Use templates/change-request.md before implementing a final tiny change.
