The previous commit's `floorPlaced` capability used `getScaledDimensions`
in `item/definition.ts` and `ColumnNodeType` in `column/definition.ts`,
but the editor's auto-format hook ran between the import edit and the
body edit and removed both as "unused" — breaking `bun dev`.
Re-add the imports.
Symptom: a shelf placed on a level with a raised slab underneath
visually clipped through it — `ItemSystem` lifted items onto slabs,
but shelves (and other floor-placed registry kinds) had no equivalent
path.
Fix: lift the slab-elevation logic out of `ItemSystem` into a generic
`<FloorElevationSystem>` keyed off a new `capabilities.floorPlaced`
config. Any kind that opts in declares a `footprint(node)` (dimensions
+ rotation used to query overlapping slabs) and an optional `applies`
predicate (skips items whose `asset.attachTo` is wall / ceiling).
The new system runs at frame priority 1 so its `mesh.position.y`
override lands before `ItemSystem` / `GeometrySystem` (priority 2)
clear the dirty mark. The spatial-grid sync's `markNodesOverlappingSlab`
also dropped its hardcoded `item` branch in favour of an iteration over
every registered kind that declares `floorPlaced` — so any new
floor-placed kind picks up slab-driven re-elevation automatically.
Tagged kinds:
- `item` — `footprint = getScaledDimensions`, `applies = !asset.attachTo`
- `shelf` — `footprint = (w, h, d)`
- `column` — `footprint = (w, h, d)`
- `spawn` — `footprint = (0.6, 1.8, 0.6)` (marker)
`ItemSystem` retains only the wall-side z-offset block (`mesh.position.z =
wallThickness / 2`). The elevation block + its `getScaledDimensions` /
`resolveLevelId` / `spatialGridManager` imports moved to the generic
system.

Wholesale move of every remaining kind into its own subdirectory under
`packages/nodes/src/`, finishing the registry-driven migration. Each
kind now ships its definition, schema (re-exported from core), and any
of `geometry` / `renderer` / `system` / `floorplan` / `tool` /
`move-tool` / `panel` / `floorplan-move` / `floorplan-affordances` /
`parametrics` / `preview` it needs — no per-kind code remains under
`packages/editor/src/components/tools/` or
`packages/viewer/src/components/renderers/`.
Deleted (replaced by registry-driven equivalents):
- `tools/{ceiling,column,door,fence,item,slab,spawn,wall,window}/...`
(boundary editors, hole editors, placement tools, move tools,
endpoint movers, curve tools, helpers, math libs)
- `ui/helpers/{ceiling,slab,wall}-helper.tsx`
- `ui/panels/{column,door,elevator,item,roof,roof-segment,spawn,
stair,stair-segment,wall,window}-panel.tsx`
- `viewer/src/components/renderers/{building,ceiling,column,door,
elevator,fence,guide,item,level,roof,roof-segment,scan,site,slab,
spawn,stair,stair-segment,wall,window,zone}-renderer.tsx`
- `viewer/src/components/viewer/legacy-system.tsx`
Added under `packages/nodes/src/`:
- `building/`, `column/`, `elevator/`, `guide/`, `level/`, `roof/`,
`roof-segment/`, `scan/`, `shared/`, `site/`, `stair/`,
`stair-segment/` packages with definition + schema + renderer / system
/ floorplan / panel as appropriate.
- New `floorplan-move.ts` for every kind that supports 2D moves
(ceiling, door, item, shelf, slab, window) — single registry-driven
dispatch path via `def.floorplanMoveTarget`.
- New `floorplan-affordances.ts` for kinds with polygon / endpoint
drags (ceiling, fence, slab, wall) — using the shared
`polygon-vertex-affordance` factories.
- New per-kind `panel.tsx` for kinds with custom inspector content
(door, item, shelf, spawn, wall, window).
- New per-kind `tool.tsx` for placement (door, item, shelf, window).
- New per-kind `move-tool.tsx` for kinds with custom 3D move flows
(door, item, slab, window).
Coordinator + manager updates in `packages/editor/`:
- `tool-manager.tsx` resolves tools from the registry only — no
hardcoded type→component map.
- `panel-manager.tsx` resolves inspector panels the same way.
- `placement-{coordinator,strategies,types}.ts` extended with
shelf-surface placement.
- `selection-manager.tsx` adds the registry-selectable fallback.
- `floorplan-panel.tsx`, `floorplan-background-placement.ts`,
`floorplan-render-context.tsx` updated for the registry layer's new
contract (props, affordance dispatch, render context).
Viewer updates:
- `viewer/index.tsx` drops legacy renderer mounts.
- `node-renderer.tsx` resolves by registry only.
- `scene-bvh.tsx`, `use-node-events.ts`, `level-system.tsx`,
`wall-cutout.tsx`, `zone-system.tsx`, `materials.ts` adjusted for
the registry-only world.
Sidebar tree nodes for ceiling / fence / slab / shelf / tree-node
updated to read from the registered nodes instead of the deleted
legacy renderer trees.
Wiki: new `plugin-authoring.md` page, README index updated.
Tests in `packages/nodes/src/index.test.ts` validate every registered
kind has the required shape.

Two related bugs caused floor items to disappear mid-2D-drag:
1. `startLevelId` did `parent.parentId` unconditionally for non-wall
parents — so for a floor item parented directly to the level (the
canonical convention from `use-placement-coordinator`), it returned
`level.parentId = building.id`. `findContainingSurface` then iterated
the building's children (levels, not slabs) and the fallback
`parentId: startLevelId` reparented the item to the building. Now we
walk the parent chain until we hit a `level` and short-circuit on
`parent.type === 'level'`.
2. `buildSurfaceItemSession` reparented floor items to a slab when the
cursor was over one. Slabs don't carry a `children` field on their
schema (only ceilings + level do), so `updateNodesAction`'s reparent
logic operated on `undefined.children` — the item dropped out of the
level→children DFS the floor-plan layer walks, and the polygon
stopped rendering mid-drag. Split into `buildFloorItemSession`
(always parents to the level, just updates position) and a
ceiling-only `buildSurfaceItemSession`. `findContainingSurface`
narrows to `'ceiling'` as the only valid target.
Matches the 3D `detachItemSurfaceToFloor` convention: floor items live
as level children, not slab children.

Item is the last Stage A-only kind to gain def.floorplan. Closes Stage C
across every registered kind.
Files added:
- nodes/src/item/floorplan.ts: buildItemFloorplan inlines a self-
contained parent-chain transform walker using `ctx.resolve`. Mirrors
the legacy `getItemFloorplanTransform` math from editor/lib/floorplan/
items.ts:
* Wall parent: rotate item.position by wall's angle, anchor at
wall.start, handle wall-side attachTo via wall.thickness offset.
* Item parent (nested): recurse for parent's transform.
* Level / slab / ceiling parent: item.position is level-local.
Returns a rotated width × depth rectangle. asset.floorPlanUrl image
overlay deferred for Phase 5 follow-up.
Files changed:
- nodes/src/item/definition.ts: wires `floorplan: buildItemFloorplan`.
- floorplan-panel.tsx: floorplanItemEntries useMemo short-circuits to
[] when nodeRegistry.has('item'). Phase 6 deletes the entire useMemo.
Stage C coverage (all 9 registered kinds):
shelf ✅ spawn ✅ fence ✅ slab ✅ ceiling ✅ wall ✅ door ✅ window ✅ item ✅
Next sessions: Stage B for door / window / wall (each large geometry
extraction), Stage D per kind (DragAction affordance ports), Stage E
(drop legacy panels), Phase 6 Stage F cleanup.

Item is the first kind to use the `def.renderer` escape hatch (custom
React component with `useGLTF` + drei + interactive widgets) — not
expressible as a pure `def.geometry`. Catalog-backed + multi-host
(free / wall / wall-side / ceiling).
Files added (packages/nodes/src/item/):
- schema.ts: re-exports ItemNode from core.
- parametrics.ts: empty groups[]. Item parametrics come from the
asset's catalog-defined interactive controls (toggles / sliders /
temperature) — too dynamic for the auto-inspector at Stage A.
Legacy ItemPanel renders the catalog-driven controls; Phase 5
Stage E will likely use parametrics.customPanel.
- definition.ts: capabilities (no `movable` — item move is bespoke
MoveItemContent that handles attachTo transitions floor↔wall↔
ceiling mid-drag; capability-driven dispatch keeps legacy mover),
parametrics, renderer (wrap-export of ItemRenderer), system
bundling ItemSystem + ItemLightSystem, toolHints matching the
user's screenshot (Place item / R rotate ccw / T rotate cw /
Shift free place / Esc cancel). defaults() casts an object
literal with a stub asset since asset is required by the schema;
createNode re-parses through ItemNode at runtime.
- renderer.tsx: wrap-export of legacy ItemRenderer (~280 lines with
useGLTF + interactive widgets — too much to duplicate at Stage A).
- system.tsx: bundles ItemSystem + ItemLightSystem.
- index.ts: barrel.
Files changed:
- packages/viewer/src/index.ts: new public exports for ItemRenderer,
ItemSystem, ItemLightSystem.
- packages/nodes/src/index.ts: appends itemDefinition.
- packages/editor/src/components/ui/panels/item-panel.tsx: panel
slider-drag fix recipe applied (nodeRef pattern, drop subscribed
updateNode dep, drop node from useCallback deps). Item panel has
scale + position + rotation sliders all subject to the cascade.
Item is the registry's stress test for `def.renderer` escape hatch.
GLB loading via useGLTF + drei works as-is; nothing in the registry
forces a pure-geometry shape on kinds that don't fit.
Phase 5 progress: shelf ✅ spawn ✅ wall ✅ fence ✅ slab ✅ ceiling ✅
door ✅ window ✅ item ✅. Nine kinds on the registry. Stair / roof /
zone / containers remain.
