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.

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.

Publication-throughput rework per the D2 design (docs/research/
2026-08-02-collision-throughput-handoff/design-note.md): O1 per-prefix
installed-key ledgers replacing the seal's full-map scans; O2 per-
landblock delta commit (LandblockReplacementApplyCursor against the
active root) replacing whole-world TransferTo; O3 empty staging root,
commit-time reflood (CObjCell::init_objects 0x0052B420 ->
recalc_cross_cells 0x00515A30), journal/peer-rebase machinery deleted
(~1,900 lines net).
Automated gates green: Runtime 999, Core physics 2,135, App 4,039/3,
Headless 79, complete solution 10,812/0/4; lifecycle gate PASS
(connected-world-gate-20260802-193029). Soak 194423: publication-side
acceptance fully met (37 -> 4 failures, all convergence dims zero,
loadedLandblocks baseline-identical, waitCue 6/9 -> 1/9).
COMMITTED AS WIP ON USER DIRECTION - NOT ACCEPTED. The user feel-test
FAILED on this tree: monsters still pop into existence at close range,
monsters spawned mid-air far ahead, static placements visibly wrong,
plus 243x "Landblock already has a full retirement receipt"
InvalidOperationException catch-retry loop during origin recenter
(launch-feeltest-oclone.log). The 4 remaining soak failures
(pendingLandblockRetirements 131/122 at the Caul->Sawato stops) and the
implementer's "exposed pre-existing" classification are under
re-judgment against that loop. Dual reviews were dispatched and then
stopped mid-flight on user direction; NO review has passed this commit.
