Wassim SAMADandClaude Opus 4.7 90702e74e2 Add relations cascade resolver (Phase 1, 1/6)
Pure traversal that walks a node's declared `relations` and returns the
full set of IDs that should be marked dirty alongside it. Two
implementations:

- `cascadeDirty(id, ctx)` — follows `hosts` (matching children) and
  `affectsSpatial` (via injected spatialQuery). Phase 3 will add
  `linkedBy: 'endpoint-match'`.
- `collectDescendants(id, ctx)` — pure subtree traversal for
  `cascadeDelete: 'descendants'` and subtree deletion tools.

Both bounded by maxDepth (default 16) and visited-set so cycles in
bad data can't loop forever.

Context-based design: spatialQuery and childQuery are injected, so the
resolver itself stays pure — the DragAction runtime can plug in
spatialGridManager-backed queries; tests pass stubs.

Today, registry has no kinds → cascadeDirty(id) always returns just
{id}. No behavior change. Phase 3 wall is the first real consumer.

11 unit tests cover empty/no-relations baseline, hosts cascade, depth
limit, spatial query, missing spatialQuery branch, cycle protection,
childQuery override, descendant collection.

@pascal-app/core

Core library for Pascal 3D building editor.

Installation

npm install @pascal-app/core

Peer Dependencies

npm install react three @react-three/fiber @react-three/drei

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>
}

Node Types

  • SiteNode - Root container
  • BuildingNode - Building within a site
  • LevelNode - Floor level
  • WallNode - Vertical wall with optional openings
  • SlabNode - Floor slab
  • CeilingNode - Ceiling surface
  • RoofNode - Roof geometry
  • ZoneNode - Spatial zone/room
  • ItemNode - Furniture, fixtures, appliances
  • ScanNode - 3D scan reference
  • GuideNode - 2D guide image reference

Systems

Systems process dirty nodes each frame to update geometry:

  • WallSystem - Wall geometry with mitering and CSG cutouts
  • SlabSystem - Floor polygon generation
  • CeilingSystem - Ceiling geometry
  • RoofSystem - Roof generation
  • ItemSystem - Item positioning on walls/ceilings/floors
