Read the trailer's video coverage.

Returns the latest VIDEO COVERAGE report on the trailer: the stitched master (the 480p preview, then the finished master) watched with its sound and scored on its quality and its adherence to the shot list — lip sync, prompt adherence, visual fidelity, motion naturalness, identity continuity, text placement, audio sync — never its story. It says which master it watched and whether that is the master the trailer has now (current), the score against the bar (gateThreshold, with vetoDimensions that fail it on their own), every finding with its timecode located in code on beats, calls and shots and the remedy that fixes it, and whether it holds the paid finish (blocksFinish; then the finish is refused with trailer_video_coverage_failed unless the writer finishes anyway). It runs by itself after every stitch; a trailer with no report answers status: "missing", never a 404. The same object is videoCoverage on GET /trailers/{jobId}/beats. Scope: story:read.
