- Live slab-stacking Y previews for all floor-placed kinds (item/shelf/spawn/column/stair) during placement + both move pathways, via a shared core resolver; canonical positions unchanged.
- Unified 3D handle system (one drag pipeline + one visual primitive) with forgiving invisible hit-areas on every handle, kept on EDITOR_LAYER so they don't poison the MRT scene pass.
- Hover + click-to-edit slab holes in 3D (manual hole -> hole editor; stair/elevator hole -> select owner); generic cross-arrow polygon-move grip; normalized handle interaction colors.
- NaN-safe node mutations + non-finite shadow-light bounds guard.
- Built on #373 (level-scoped alignment / registry slab tool); #373 owns X/Z alignment, this owns Y floor-stacking.
Matches the wall / slab / curve-wall tool pattern: emit
sfx:grid-snap only when the snapped position changes (cursor crosses
a grid cell), not every frame of mouse movement within the same cell.
Tracked via a `previousSnapRef` per tool, reset when the tool
re-activates.

User-visible follow-ups after first running the Phase 2 spike.
Spawn tool now matches legacy UX:
- CursorSphere from @pascal-app/editor for the placement indicator
(ring + line + tool-icon tooltip) — was a plain sphere mesh.
- Emits sfx:structure-build on commit + setTool(null) + setMode
('select') to exit build mode, matching legacy spawn-tool.
Shelf tool placement:
- Emits sfx:structure-build on commit.
- Cursor preview now shows top board + brackets (was just the top),
matching what gets placed.
Shelf selectable from the 3D canvas:
- ShelfEvent type added to @pascal-app/core/events/bus.
- 'shelf' added to NodeConfig in useNodeEvents.
- ShelfRenderer wires `useNodeEvents(node, 'shelf')` handlers onto
every mesh. Clicks/hovers now bubble through the editor's selection
manager and update useViewer.selection.
Shelf appears in the sidebar:
- ShelfTreeNode component (mirrors spawn-tree-node's shape +
selection/hover/rename wiring; lucide Layers icon).
- TreeNode dispatcher adds a `case 'shelf':` arm.
Framework changes:
- @pascal-app/editor exports CursorSphere alongside triggerSFX.
- @pascal-app/nodes now declares @pascal-app/editor as peer/dev dep.
Pre-existing typecheck errors in @pascal-app/editor (ceiling-tree-node,
fence-tree-node, slab-tree-node, scene.ts) are unchanged — present on
main and not introduced by this commit.
630 tests still pass.

The first time registry-driven nodes actually run in the editor.
Spawn migration (under NEXT_PUBLIC_USE_REGISTRY_FOR_SPAWN flag):
- New packages/nodes/src/spawn/ folder with renderer, tool, schema
(re-exported from core), parametrics, definition, index.
- Spawn definition appended to builtinPlugin.nodes only when the flag
is set. With the flag off, the Phase 0 shims fall through and the
legacy SpawnRenderer / SpawnTool keep ownership.
- New no-props SpawnTool reads activeLevelId from useViewer directly,
matches legacy placement behavior (half-meter snap, singleton-per-
level, replace-on-reclick).
- Structural parity test (9 cases) validates definition shape +
schema identity. Pixel-diff defers to Phase 4 alongside more nodes.
New shelf node (no legacy — registered unconditionally):
- ShelfNode schema in core/schema/nodes/shelf.ts (hand-maintained
AnyNode union for now; Phase 6 derives the union from the registry
and moves the schema fully into nodes/shelf/).
- packages/nodes/src/shelf/ folder: pure geometry builder
(buildShelfGeometry returns a Three.js Group of top board +
brackets), R3F renderer that mounts the built group, no-props
placement tool, parametrics descriptor (width/depth/thickness/
height/bracketStyle/color), definition with surfaces.top stackable
surface for future stacking, and presentation metadata for the
palette.
- 13 unit tests across schema bounds and geometry behavior.
- Palette wiring: 'shelf' added to StructureTool union + an entry in
the structure-tools array (placeholder icon, replaced in Phase 4
when palette is registry-driven).
Framework changes:
- @pascal-app/viewer now exports useNodeEvents from its public barrel
so node bundles in @pascal-app/nodes can subscribe to node-specific
pointer events. (Used by spawn renderer; shelf renderer skips it
for now since useNodeEvents has a hardcoded kind list — Phase 4
generalizes it via the registry.)
- @pascal-app/nodes gains @pascal-app/viewer as a peer + dev dep so
node bundles can import from it.
630 tests pass across 76 files (22 new this phase). Editor app
continues to ship green with both legacy spawn and the new shelf
node co-existing through the Phase 0 dispatch shims.
To validate end-to-end in dev:
- bun dev:community → open editor → click 'Shelf' in structure
toolbar → click to place. Confirms full registry path
(NodeRenderer dispatch + ToolManager dispatch + sceneRegistry
byType Proxy).
- Set NEXT_PUBLIC_USE_REGISTRY_FOR_SPAWN=1, restart dev, place spawn
→ visually identical to legacy. Confirms parity.
