Objective

Create the scene-level working environment that answers How do all the pieces synchronize over time?

Product direction

Use the Human-approved reference model: screenplay/source preview, playback preview, cue inspector and a block-based timeline similar to an editing application.

Initial timeline lanes:

• Dialogue;
• Action;
• Shot;
• Audio.

Later lanes may expose Lighting / FX / Transition / Camera Motion when they carry real editable intent.

Contract

• Timeline cues reference real Scene/Beat/Shot/source identities; they are not free-floating UI blocks.
• Preserve the originating Block/Mini-Block and written source address in the context strip.
• Selecting a cue should reveal source/owner/timing/intent details and provide navigation back to the originating story material.
• Storyboard/Previs evidence is projected into the workspace rather than copied into a new canon store.
• Scene → Beat → Shot → Frame becomes understandable visually, without forcing one-to-one counts.
• Playback may use rough/previs/candidate media where available; missing media remains truthful.

Afterglow acceptance

A known Afterglow scene within a mapped Block can open with the correct source text and any real Dialogue/Action/Shot/Audio timing evidence while preserving Block/Mini-Block provenance.

Exit criteria

1. One Scene Workspace surface synchronizes source, playback, inspector and timeline.
2. Timeline objects have stable source/provenance refs.
3. Moving/editing a cue creates a bounded creative change rather than mutating unrelated story state.
4. The Human can navigate from timeline cue back to source writing and forward to Production intent.
5. Afterglow fixture proves deterministic identity/order/timing relationships without fabricating absent cues.
