Movement: CommitSetPosition's RefreshPositionRows/ReplacePositionRows and
the staged apply publish the retail render product from the exact cell
list collision just used, the transition's cell_array retail feeds
add_shadows_to_cells in CPhysicsObj::SetPositionInternal @0x00515330
(pseudo-C 283526-283539); the separate move-path bbox recompute is deleted.
calc_cross_cells @0x00515230 stays the distinct full-recompute path
(PhysicsShadowCommitAction.Recalculate).
Children (Contract B recursion): ShadowObjectRegistry.AttachChild/DetachChild
give an attached object the root's current cells as part entries only,
republished whenever the root's array changes, detached at withdrawal and
cascaded from the root's Deregister; nested attachment resolves to the root
with a bounded, cycle-safe chain. EquippedChildRenderController attaches at
realization (FromSetupRenderParts over the child's Setup) and detaches at
its single removal funnel. WalkProductionWorldData's dynamic sweep reads
TryGetRetailCellArray directly; the 64-hop parent-chain walk and its
FindParentLocalId plumbing are deleted. CollisionWorldState.Clear now
also clears the retail products.

WalkProductionWorldData no longer floods; its indoor and outdoor static
sweeps read ShadowObjectRegistry.TryGetRetailCellArray (retail's
calc_cross_cells_static @0x00515160 -> AddPartsShadow @0x00517e40
CELLARRAY, computed once at registration). The App-owned render flood
(ResolveStaticRenderCells, its fingerprint cache, the primitive-Setup
special case) and Core's ComputeStaticRenderCells are deleted. The one
remaining fallback, an entity the physics publisher has not registered yet
while the projection journal already published it, buckets to the authored
parent cell and is counted per frame (UnregisteredStaticRenderFallbackCount)
for chunk 5 to judge on the connected route.
The Facility stair pin now registers at the projection's own entity id
(the old pure-function test never carried identity) and reads the retail
array; the installed-DAT comparator compares retail against collision.
