Scenario
The script stays authoritative. Downstream outputs can become stale when it changes.
Sections & Beats
One beat equals one visual responsibility. Dependencies are inspectable.
Narration
Actual WAV duration drives beat timing. Sample beats use bundled local audio. Custom beats use clearly labelled browser-local timing simulation.
Whisper Review
Transcript corrections can change captions without redefining the beat duration.
Media Review
Every beat owns one final visual slot before assembly.
Timeline
Visual, narration and subtitle state projected from the same beat model.
Change the script in the guided demo to see revision impact reach the timeline.
Project Health
Production checks are explicit. Claude-assisted reasoning is a roadmap capability, not simulated here.
Planned uses include long-context script analysis, structured beat planning, revision-impact reasoning and consistency QA — behind explicit review boundaries.
