ShadowObjectRegistry computes the CELLARRAY once per registration under
Contract A (cylsphere route from the Setup's collision cylspheres, else the
bbox route over the whole visual part array) and derives BOTH products from
it: the collision rows (_entityToCells/_cells, CShadowObj per cell via
add_shadows_to_cells @0x00514ae0) and the per-part render entries
(AddPartsShadow @0x00517e40). The second, independent collision flood is
gone. A caller that supplies no part array floods from its collision shapes
exactly as before, so every legacy expectation holds byte-for-byte.
The staged SetPosition pipeline now carries the retail part array, cell
array, route, and entries through TryCaptureOwnerState/InstallOwnerState
and publishes them beside the collision cell replacements, honoring the
keep-when-empty rule (SetPositionInternal num_cells gate, pc:283540) for
both products together; two new tests pin a cross-cell move and the
keep-when-empty case. Behavior change, retail-exact: an object with
decorative non-BSP parts now has its collision shapes registered in every
cell those parts reach (pinned by a two-cell fixture); all-BSP objects are
unchanged. Movement paths still take collision cells from the transition
and recompute the retail product separately; chunk 4 unifies them on the
transition's array as retail does. No particle emitter reaches this registry.

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.

Campaign OVERHAUL S2 chunk 1 (Core half). ShadowObjectRegistry accepts the
object's whole visual part array as an optional registration input and
computes retail's CELLARRAY from it as a retained side product:
- route per CPhysicsObj::calc_cross_cells_static @0x00515160: cylsphere
(CObjCell::find_cell_list @0x0052b9f0 over the Setup's authored
cylspheres, carried as the Cylinder shapes of the COLLISION dispatch) when
(state & 0x10000) == 0 and a cylsphere exists, else the bbox route
(find_bbox_cell_list @0x00510fc0 via CellTransit.BuildShadowCellSetFromParts
over every visual part: physics sphere else drawing sphere, part box);
- per-cell part entries in array-then-part order for every part
(CPartArray::AddPartsShadow @0x00517e40), clip planes required iff the
array has more than one cell;
- Deregister clears everything (remove_shadows_from_cells @0x00511230);
UpdatePosition/CommitSetPosition recompute; ReplaceMultiPartPayload swaps
the part array without re-flooding.
_entityToCells and _cells are untouched; no production caller passes the
part array yet (chunk 1b), so this is a zero-behavior change. The lead
corrected the implementer's route decision, which had inspected the visual
part array for cylinders; retail's GetNumCylsphere reads Setup collision
data. Core Physics 2,202/2,202.
