SmoothOccupancyRegistry

Shared node-keyed bookkeeping for the smooth occupancy registries. Owns the entry list, node identity lookups, freed-node pruning, snapshot and restore, and the projection rebuild from world_registry. The dimension subclasses SmoothOccupancyRegistry2D and SmoothOccupancyRegistry3D own the geometry: entry records, world bounds, and the positive-area overlap test. Key design decisions:

• Occupancy is registered only after a successful commit.
• Failed placements create no registry record.
• Move operations exclude the object being moved (update in place).
• Demolish unregisters occupancy.
• Shared world: all entries are checked regardless of session. Split-screen players in the same world see each other's objects. Separate registries are for separate placement worlds only.

Members

Name	Kind	Summary
placed_node	Property	One occupied footprint, keyed by a weak reference to its placed node. Weak reference to the placed node. Entries whose node was freed are pruned by SmoothOccupancyRegistry.clear_invalid_entries().
get_placed_node	Method
is_node	Method
copy_for	Method
to_record	Method
to_debug_record	Method
world_registry	Property	Shared committed-placement authority. rebuild_from_scene() reads only SMOOTH records it holds; save/load itself uses the restore coordinators.
