Three related editor fixes surfaced while debugging a captured house
project that rendered an infinite wall and failed to load.
Infinite wall (core/systems/wall/wall-mitering.ts):
Junction miters are line-line intersections, so the joint point sits
~halfThickness/sin(theta) from the junction. The only guard was an
exact-parallel check (det < 1e-9), so two walls meeting at a shallow
angle (a room-preset preview dragged onto an existing wall, or a wall
drawn nearly collinear to its neighbour) produced a joint point far
away — an infinite spike. Add a miter limit: reject joints farther
than 10x half-thickness from the junction and fall back to a square
joint, exactly like the parallel case.
Scene load failure (core/utils/heal-scene-graph.ts + validate-build-json
+ use-scene migrateNodes):
Capture wall-merge could leave a `children: [null]` entry (see the
matching merge-walls.ts fix in private-editor) and zero-length walls.
`null` children fail wall schema validation, so the whole scene fails
to load. Add a shared heal step — strip non-string child refs, drop
childless zero-length walls — run on every load path: import
validation now repairs instead of hard-failing (with a warning), and
setScene heals on the prod project-load path too.
Grid snap (nodes slab/ceiling/spawn tools):
These tools hardcoded a 0.5 m snap (Math.round(x*2)/2) and ignored the
editor's grid-snap setting, so the cursor jumped by 0.5 while later
vertices already followed the configured step. Route them through
snapPointToGrid / snapScalar with gridSnapStep.
Adds unit tests for the miter limit and the heal step.

Dual review pass (Claude multi-angle + Codex release-quality). One
correctness fix and the agreed do-now cleanups:
- fix: clone-scene-graph remaps roofSegmentId like wallId in both
clone paths — duplicated scenes/levels kept pointing roof-hosted
children at the original segments.
- extract the settled, stateless roof target/cursor math shared by the
four door/window tools into shared/roof-wall-opening-placement.ts
(resolveRoofWallOpeningTarget + getRoofWallOpeningCursorPose +
worldToSelectedBuildingLocal); tools keep the stateful lifecycle
(drafts, undo/temporal, commit field lists). −199 net lines.
- rename host-generic state: currentWallId→currentHostId,
markWallDirty→markHostDirty (they hold segment ids too); capability
cascadesViaHostSegment→dirtyHandledByOwnSystem (behavior-facing,
before the public API hardens).
- drop getRoofAccessoryKinds from core's public API — its only caller
was the standalone Build tab, which now enumerates the registry
inline with its app-specific filter.
- window move-tool uses the shared stripPlacementMetadataFlags; stale
"segment-local" comment fixed.

Stair system (full stack):
- New StairNode + StairSegmentNode schemas with flights, landings, L/U-shapes
- StairSystem: geometry generation with throttled per-frame updates
- Stair tool, edit system, panels, tree node, and renderers
- Event bus types, scene registry, and command palette entries
Scene graph utilities:
- cloneLevelSubtree: deep-clone a level with remapped IDs
- forkSceneGraph: clone + strip scan/guide nodes for project forking
Core improvements:
- Read-only mode on scene store (blocks create/update/delete when locked)
- readOnly guards on node-actions and collection actions
- Upload store for scan/guide file upload handling
Viewer state:
- previewSelectedIds for box-select live preview
- hoverHighlightMode (default/delete) for delete-mode hover outline
The original implementation used spread ({ ...node }) which only shallow-copies.
Nested objects (asset, polygon, position tuples, metadata) would share references
between the original and cloned scene, meaning mutations to the clone could
corrupt the original.
Also removed resolveChildRefId helper — children arrays in the schema are always
string IDs, so the object-with-id handling was dead code.
