Lays down the wall folder under @pascal-app/nodes with everything needed
to register the kind, but intentionally without runtime wiring:
- schema.ts re-exports WallNode from core (door/window/item still type
their parentId against WallNode.shape.id, so the schema stays canonical
there for now).
- parametrics.ts declares thickness / height / curveOffset for the Phase 4
inspector. Endpoints and host children are edited via affordances, not
number inputs, so they're not in parametrics.
- definition.ts encodes capabilities (surfaces, selectable, duplicable,
deletable — no movable since wall's move is bespoke endpoint-drag),
relations (hosts doors/windows/items, affectsSpatial slabs/ceilings/
zones, linkedBy endpoint-match, cascadeDelete descendants), and the
presentation metadata for the palette. Renderer / system / tool fields
are deliberately absent — the existing wall-renderer.tsx and
wall-system.tsx keep serving wall until milestone B.
- feature-flag.ts gates the eventual registration via
NEXT_PUBLIC_USE_REGISTRY_FOR_WALL (same pattern Phase 2 used for spawn).
- wallDefinition is NOT yet appended to builtinPlugin.nodes — registration
is what flips the Phase 0 dispatch shims, and we don't want that until
the runtime port lands. Until then this file is metadata-only.
Two type-side changes pulled forward from Phase 4 to make a metadata-only
definition compile:
- NodeDefinition.renderer becomes optional (the three-checkbox model
documented in wiki/architecture/node-definitions.md already promises
this). RegistryRenderer in node-renderer.tsx gains a null-guard so an
undefined renderer cleanly falls through to the legacy switch.
No runtime behavior change. Walls render and behave exactly as before.
