Fix pass over 2D reference-image (guide) handling plus two adjacent repairs: - North is now world −Z (FLOORPLAN_VIEW_ROTATION_DEG 90 → 0, mirrored in world-grid-snap + mcp README; floorplan-panel de-dupes its local copy). A rotation-0 north-up scan reads upright when the compass says aligned, and "align north" maps to camera azimuth 0 instead of a 90° jump. - Guide resize cursor: custom double-arrow cursor aimed at the dragged corner in screen space — accounts for image aspect (was atan2(±1,±1), square-only), the guide's own rotation, and the floorplan view rotation the overlay group renders inside (was ignored entirely). - R/T rotate a selected reference (guide/scan) in ±45° steps; references live in selectedReferenceId, not the viewer selection, so both arms get the reference-first branch the Delete arm already had. Locked guides skip. - 2D-only mode hides the Top View button (drives the display:none 3D camera); orbit stays — it spins the synced floorplan view. - Set Scale UX: locked guides stay clickable (calibration auto-lock made them unselectable until reload); starting the flow from 3D switches to 2D; the length input pre-fills the drawn length in the pre-selected unit (imperial pre-filled meters labeled feet); Set Scale flips into Cancel while the flow runs (mirrored via referenceScaleActiveGuideId); Hide/ Clear Scale only render once calibrated; Escape cancels (global arm + dialog); Clear Scale and Replace Image drop the calibration auto-lock; discoverability: corner-hint row + panel nudge for uncalibrated guides. - healSceneNodes: strip child refs whose child's parentId names another parent (stale reparent leftovers rendered a window twice — duplicate React keys in 2D, doubled hosted geometry in 3D) and same-array dupes. - Editor accepts onLoaderChange so hosts can measure open-to-interactive time (community wires it to a PostHog timing event).

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>
}
