User feedback from eval 5 exposed a real R4 failure mode: - p2 Thread: Maya's card persisted across scenes (good) but often landed in positions that didn't fit the scene's content hierarchy (bad). Semantic-mismatch. - p3 Vermeer: painting zoomed to 2.1x in scene 2, blocking the right-column metadata the scene subagent had authored. Size- collision. Root cause: expansion identifies the subject, scene subagents author their scenes INDEPENDENTLY (picking their own layouts), and the scaffold tweens the subject's position/scale across transitions as an afterthought. Scene subagents don't know how big the subject will be in THEIR scene, so they place their chrome wherever, and then the scaffold's tween scales the subject up or moves it into regions already filled. Fix: expansion pre-plans the choreography BEFORE the per-scene detailed breakdown. Per-scene block specifies: - position (center x, y) - scale - size_envelope (actual on-screen footprint in this scene) - role (focal / background anchor / data-point / glyph-slot / ...) - reserved_region (rectangle scene subagent must leave empty) - scene_must_avoid (short instruction) Orchestrator (multi-scene.md) passes each scene subagent its scene's choreography block plus the contract: - The scaffold owns the subject's DOM + timeline. - Your scene layout MUST respect the reserved region. - Design your scene chrome around the element's role in this scene. - Do NOT animate the persistent subject in your timeline. Invariants: - Size envelope reflects the SETTLED state (if the subject scales up during the scene, reserve for the larger size). - Scene-to-scene positions trace a visually-coherent path, not leapfrogs. - Role changes drive reserved-region size. Branch worktree only. Not synced to installed main skill path.
