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.
