Add bullets to §4.B for surfaces that landed after the 2026-05-20
skill update:
- def.capabilities.paint (PaintCapability dispatch for paint mode)
- def.capabilities.floorPlaced (generic FloorElevationSystem)
- def.surfaceRole (Solid/Rendered/Clay render-mode pipeline)
Also add a verb-not-host-kind rule and mark capabilities.roofAccessory
as documented tech debt — extending the *Accessory / *Hosted shape is
now a blocker rather than a precedent.
