World-scoped authority for committed Grid Placement records. It owns only roots committed or deliberately rehydrated by Grid Placement. Environmental physics and arbitrary scene nodes remain validation inputs. GRID and SMOOTH records share this identity/conflict authority, while EDGE/FACE/socket records deliberately carry null cross-mode AABB evidence.
