Price, then run, the finish of a trailer.

Finishes the cut: every selected take is upscaled from its 480p render to the delivery class — 720p unless the writer asked for 1080p (deliveryResolution, else the trailer's own class) — the on-screen text layers are composited over the finished cut, and the finished master is stitched. Nothing is generated again, and a take already finished at the class is reused, not charged twice. TWO CALLS, PRICE FIRST: sent WITHOUT confirmed it prices the finish and reserves nothing (quotedOnly: true, the lines, and a warnings entry per flagged take the writer kept); sent again with confirmed: true it reserves exactly those lines and starts the finish (finishing, then complete). Refused before the price while any call has no selected take (a call with no accepted take: render it again), and while the master the writer is looking at FAILED its video coverage (trailer_video_coverage_failed, details.videoCoverage: the score, the bar and the findings with their fixes) — unless acknowledgeVideoCoverage: true, which only the writer's own choice to finish anyway may set. Coverage still running, one that could not run, or one of an earlier master never holds the finish: the quote's warnings say so. A trailer with no screenplay is finished from its app captures and title cards with no take to upscale, and is refused (trailer_capture_only, naming the beats) while any beat is blank or no beat plays a capture. Review or complete (finishing again at a new class) only. Requires Idempotency-Key. Scope: artifact:publish.
