hayba-new-scene

name	hayba-new-scene
description	Use when the user asks to generate a new scene from scratch — coordinates moodboard → references → spatial planning → asset placement → physics validation → CLIP scoring.

hayba-new-scene

Workflow

1. Call hayba_generate_moodboard with the scene brief — get 3-5 reference embeddings.
2. Call hayba_fetch_references for any specific keywords — extend reference set.
3. Call level_get_spatial_index to get the level cognitive map (cells + cluster labels).
4. Plan biome zones top-down: assign each World Partition cell a target cluster label.
5. For each zone: call pcg_create_graph (terrain) → pcg_execute_graph → foliage_paint_at.
6. Dress hero areas: actor_spawn from Content Browser assets matched by asset_search.
7. Call scene_validate_physics (with deep_check: false first; only true for hero shots).
8. Call editor_capture_viewport + hayba_compare_clip_score against moodboard refs.
9. If score < 0.65, invoke hayba-refine-scene.

Important

• Always start with the moodboard. Do not place assets before establishing references.
• Use scene_export mode "relational"; do not use "flat" unless explicitly asked.
• Record every spatial decision to memory with a clear intent string.
