Three bugs surfaced after the Stage E node-registry migration:
1. Ceiling intercepts 3D hover/click selection
Selecting via the floor-plan helper or the boundary-editor handles
is the intended flow; a direct 3D click on the ceiling should fall
through to whatever's underneath. `SelectionManager` now early-returns
on `ceiling` in onEnter/onLeave/onClick, so `event.stopPropagation`
is skipped and the ray reaches the item/wall/floor below.
2. Ceiling item placement: final click does nothing
When a ceiling-attached draft hangs in front of the ceiling-grid
mesh, the click ray hits the draft first and fires `item:click`,
not `ceiling:click`. `onItemClick` already forwards self-clicks to
shelf-surface / item-surface hosts; this PR adds the matching
ceiling branch so the commit lands on the ceiling under the cursor.
3. Floor-plan item move drift after the commit click
Two contributing causes, both fixed:
- `usePlacementCoordinator`'s `useFrame` lerped the draft mesh
toward `gridPosition.current` (the item's pre-move spot) every
frame, fighting React's render from `scene.position` while the
2D `FloorplanRegistryMoveOverlay` drove the move. Gated the lerp
on a `has3DPointerDrivenMoveRef` flag set on first 3D pointer
event — pure 3D drags are unchanged.
- The overlay's pointer-up handler skipped a final `session.apply`
and committed at the last pointermove position. Browsers don't
guarantee a pointermove right before pointerup, so a quick click
after a drag could land a few pixels off. Re-apply at pointer-up
coords so commit matches where the user actually released.

import { CameraControls } from '@react-three/drei'
function App() {
return (
<Viewer selectionManager="custom">
<CameraControls />
</Viewer>
)
}
Viewer State
import { useViewer } from '@pascal-app/viewer'
function ViewerControls() {

const setLevelMode = useViewer(s => s.setLevelMode)
const wallMode = useViewer(s => s.wallMode)
const setWallMode = useViewer(s => s.setWallMode)
return (
<div>
<button onClick={() => setLevelMode('stacked')}>Stacked</button>
<button onClick={() => setLevelMode('exploded')}>Exploded</button>
<button onClick={() => setWallMode('cutaway')}>Cutaway</button>
<button onClick={() => setWallMode('up')}>Full Height</button>
</div>
)
}
Asset CDN Helpers
import { resolveCdnUrl, ASSETS_CDN_URL } from '@pascal-app/viewer'
// Resolves relative paths to CDN URLs
const url = resolveCdnUrl('/items/chair/model.glb')
// → 'https://pascal-cdn.wawasensei.dev/items/chair/model.glb'
// Handles external URLs and asset:// protocol
const externalUrl = resolveCdnUrl('https://example.com/model.glb')
// → 'https://example.com/model.glb' (unchanged)
