Wassim SAMADandClaude Opus 4.7 ffc497c67a editor: gate Load Build behind a verification dialog

Loading JSON previously called setScene blindly and crashed when
the file held schema-invalid nodes (e.g. items missing `asset`).
The new dialog parses the file, runs validateBuildJson in core,
and surfaces structure counts (site/building/levels/walls/doors/
windows/items/slabs/ceilings/zones/scans), floor area, and a
per-node Schema Details list grouped by type. Import is blocked
when any hard error exists.

Two schema bugs the validator surfaced are fixed here too:

- SiteNode.children is now an id array like every other node
  (was a discriminatedUnion of full objects; three readers carried
  a string-or-object ternary that's now dropped). migrateNodes
  flattens legacy nested-object children on load. Default-scene
  seed and photo-to-scene MCP builder updated to pass `building.id`.
- LevelNode.children now includes shelf — the editor allowed it
  but the schema didn't. The schema-vs-registry-as-source-of-truth
  discussion is captured in plans/editor-node-registry.md.

@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
