Borrow the exact prior-completed landscape visibility transaction and S2 CELLARRAY owner for the opt-in IA-24 directional-shadow pack. Select terrain by authored 1..64 cells, ordinary casters by CELLARRAY, and buildings by outdoor EffectCellId with no fallback.
Keep retained caster/material/terrain topology stable across visibility-only frames. Publish exact arbitrary active instance runs and bounded terrain commands through separate selection sequences; preserve transform-journal, fade/retry, deferral, shader/RHI, ordinary world, and pack-off behavior. Amend IA-24 and the S5 ledger.
Pre-commit gates: Release solution build 0 warnings/0 errors; focused visibility/frame/caster/prepared/GPU/terrain/pack lane 137/137; warmed caster/prepared/terrain selectors 0 B; git diff --check clean. Official hermetic and InstalledDat evidence intentionally run post-commit from this exact clean tree.
Mutation evidence (each restored exactly): (1) CELLARRAY->Parent first failed PriorLandscapeSelection expected [201,202,203,205], actual [204,205]. (2) all resident terrain first failed Assert.Single with 3 commands. (3) building EffectCell->anchor first failed expected trailing 205, actual 206. (4) admit missing membership first failed with extra 204. (5) completed->building scratch first failed completed-view Assert.True, expected true/actual false. (6) selection advanced BuildSequence first failed expected 1/actual 2. (7) alternating->prefix first failed active command count expected 3/actual 1.

Chunk 5 (consumer cutover): WalkProductionWorldData's per-cell views are
borrowed from ShadowObjectRegistry.GetRetailPartEntriesInCell and resolved
through RenderSceneQuery.TryGetByLocalEntityId; every render-side sweep,
bucket, parent-cell and root-position fallback is deleted (AD-116 for the
one-frame registry→scene window, counted in UnregisteredRenderMembershipCount).
A live entity with visual parts but no collision geometry registers
render-only (LiveEntityCollisionBuilder computes the part array before the
empty-shapes gate).
Closeout fixes found while landing it:
- RefloodOwnerForLandblock forwards the retained part array — a reflood is
retail's recalc_cross_cells over the SAME CPartArray; without it every owner
touched by a landblock replacement commit lost its render membership.
- Non-colliding DAT statics register render-only from BOTH publishers
(LandblockPhysicsPublisher.PublishStaticEntity,
LandblockPhysicsContentBuilder.RegisterRenderOnlyStatic). The G2 self-gate
pixel diff caught them vanishing (Facility Hub wall panels): retail floods
every object regardless of collision (CEnvCell::init_static_objects
0x0052c350, add_shadows_to_cells 0x00514ae0).
- S2 dual review fix batch (arch + retail lens, lead-verified):
Suspend clears the retail product (remove_shadows_from_cells 0x00511230 is
one transaction); AttachChild/DetachChild advance the mutation revision so
a prepared SetPosition cannot clobber a child's rows; an attached child
never floods on its own re-registration; RemoveLandblock and the non-rooted
RetireOwnerFromLandblock prune retail rows (render-only statics end with
their landblock); a render-only owner's no-cell-array commit republishes at
its destination cell (AD-117); an empty non-null part array is treated as
null; per-move closures/LINQ replaced by index loops; EnvCell shells stay
out of the scene's LocalEntityId index (payload-less records); the index
predicate compares the id; the dead per-cell scene indices are deleted.
Register: AD-116 (chunk 5), AD-117 (four residual Contract A/B readings).
Evidence: s2-membership-ownership-map.md §8 (chunk 5) and §9 (closeout).
