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.

Move streamed terrain/cell/building and static collision publication behind a focused update-thread owner. Preserve retail publication order while making replacement and retirement exact by logical landblock ownership, including current-cell rebasing and adjacent-seam isolation.

The "consumed by nobody (zero behavior change)" / "INERT in Stage 1 (no writer)"
comments predate the UCG becoming load-bearing. Verified against the call sites:
CellGraph is populated unconditionally in CacheCellStruct (before the idempotency
+ null-BSP guards, so BSP-less cells are included) and consumed for the player
render/lighting root (CurrCell, written at the PhysicsEngine.UpdatePlayerCurrCell
player chokepoint; read by GameWindow:7502/7717), the universal id->cell resolver
(GetVisible), the 3rd-person camera cell (FindVisibleChildCell), and the
block-local terrain origin (TryGetTerrainOrigin, read by CellTransit:484/736).
Comments only — no behavior change. Core suite 1445 passed / 2 skipped.

The player's outdoor cell froze at the last in-block cell the moment they
walked over a landblock boundary (10,449-frame playerCell freeze in the
2026-06-09 capture; whole neighbouring-block interiors unenterable, plus
the running-distortion from the stale render anchor). Root cause: the
add_all_outside_cells port clamped BOTH the candidate proposal and the
find_cell_list containing-cell pick to the current landblock's 8x8 grid,
in a frame that silently assumed the current block sits at world origin.
One step over the line -> zero candidates -> FindCellSet returns
currentCellId forever.
Retail has no such clamp. Its cell math runs in a GLOBAL landcell grid
(lcoord 0..2039 spanning the map): get_outside_lcoord = blockid_to_lcoord
+ floor(blockLocalPos/24) with no bounds besides the map edge, and
lcoord_to_gid re-derives the landblock id from the lcoord's upper bits —
crossings are inherent, never special-cased.
The fix, decomp-cited throughout:
- New AcDream.Core.Physics.LandDefs: in_bounds (pc:68509),
blockid_to_lcoord (pc:68520), inbound_valid_cellid (pc:163438),
gid_to_lcoord (pc:163500), lcoord_to_gid (pc:171859),
get_outside_lcoord (pc:438690), adjust_to_outside (pc:438719).
Cross-checked against ACE LandDefs.cs; three artifacts documented and
avoided: BN's int8_t mis-render of block_y, BN's dropped 192f
BlockLength constant, and ACE add_cell_block's "FIXME!" same-block
guard (an ACE divergence, not retail).
- CellTransit.AddAllOutsideCells rewritten as the faithful sphere
variant (pc:317499 @0x00533630): adjust_to_outside re-seats the
(cell, position) pair cross-block, check_add_cell_boundary (pc:317229)
adds up to 3 neighbours by global lcoord, add_outside_cell (pc:317056)
has no same-block filter. adjust_to_outside failure breaks the sphere
loop (pc:533699 verbatim).
- BuildCellSetAndPickContaining: the outdoor containing-cell pick is now
the global XY-column under the sphere centre (AdjustToOutside), not
the [0,8)-clamped current-prefix reconstruction. Interior-wins order
and current-cell-first hysteresis unchanged.
- World->block-local frame conversion via the landblock origin already
registered in CellGraph (new TryGetTerrainOrigin); Zero fallback
preserves the legacy anchor-block assumption for unregistered terrain.
- Cross-landblock building entry comes free: the candidate snapshot now
contains neighbour-block landcells, so GetBuilding/CheckBuildingTransit
fire for cottages across the line (the capture's one failing entry).
Investigated FIRST per the pickup brief: the b3ce505#98 stopgap gate is
definitively exonerated — it is a collision-object query gate that fires
only for indoor primary cells; no membership path touches
ShadowObjectRegistry.
Tests: 31 new (25 LandDefs conformance incl. capture-geometry goldens
0xA9B40031 -> 0xA9B30038/0xA9B30034 and the northbound return; 4
AddAllOutsideCells cross-block; 3 FindCellSet membership goldens incl.
the non-anchor-frame origin conversion). Full suite: 294+218+420 green;
Core 1369 green + the 4 pre-existing door/#99-era failures + 1 skip
(unchanged from baseline).
Pseudocode + artifact notes:
docs/research/2026-06-09-landdefs-outside-cells-pseudocode.md.
Remaining acceptance: live boundary walk with ACDREAM_PROBE_CELL=1
(ISSUES.md #106).

Port CEnvCell::find_visible_child_cell @ 0x0052dc50 (pseudo_c:311397): walk
rootId's StabList + the root itself, return the first EnvCell whose
PointInCell is true for worldPoint. Used to resolve the camera cell in
3rd-person from the physics cell graph rather than a fresh AABB reclassification.
Root is always the player cell (preserves U.4c flap fix). Returns null when
no stab-list cell or root itself contains the query point.
Confirmed (T3.3 Step 1): no production call site uses FindCameraCell for the
camera projection — the only AABB camera resolver is now deleted (T3.1).
FindVisibleChildCell is wired implicitly via Stage 4 (camera-outside-door scenario);
no GameWindow call site needed in Stage 3.
