Builds a 15200-node fixture (50×100 wall grid + 8000 hosted doors + 200 sparsely-indexed slabs) and runs `cascadeDirty` 1000 times with warm-up. Reports p50/p95/p99/mean/max in ms. Runs via `bun run bench:registry` from the core package. Today: p95 measured at ~0.002ms — three orders of magnitude under the Phase 1 gate of 2ms. Headroom is substantial; we'll only revisit this if Phase 3 wall introduces `linkedBy: 'endpoint-match'` and pushes the inner cascade past the gate. Not wired into CI for v1 — regressions reviewed manually before phase gates. Output is JSON so a future CI step can diff against a baseline.

What's Included
- Node Schemas - Zod schemas for all building primitives (walls, slabs, items, etc.)
- Scene State - Zustand store with IndexedDB persistence and undo/redo
- Systems - Geometry generation for walls, floors, ceilings, roofs
- Scene Registry - Fast lookup from node IDs to Three.js objects
- Spatial Grid - Collision detection and placement validation
- Event Bus - Typed event emitter for inter-component communication
- Asset Storage - IndexedDB-based file storage for user-uploaded assets
Usage
import { useScene, WallNode, ItemNode } from '@pascal-app/core'
// Create a wall
const wall = WallNode.parse({
points: [[0, 0], [5, 0]],
height: 3,
thickness: 0.2,
})
useScene.getState().createNode(wall, parentLevelId)
// Subscribe to scene changes
function MyComponent() {
const nodes = useScene((state) => state.nodes)
const walls = Object.values(nodes).filter(n => n.type === 'wall')
return <div>Total walls: {walls.length}</div>
}
