- the LandCell event doc states the deferred cross-block batch rule (the
same-landblock lookahead text was stale);
- the AlphaSubmitMark arm's comment gives the true reason it is not a
flush point (it only enqueues into the CPU alpha list; the drain leaves
flush first);
- the pending terrain batch is cleared with the other transient frame
lists in AbortFrame/BeginFrame;
- CompleteWalkTerrainFrame runs in a finally so a throwing Replay cannot
leak its accumulated ticks into the next frame's sample;
- CopyRenderableEmittersInCell keeps its own doc comment;
- the outdoor-root LandCell pin now observes one real cell turn after its
terrain;
- the oh1 landscape contract's stale "whole pre-stage" prose is resolved.

Fixes the three-lens review blockers against 671eb3ad4 (S3 section 9.6 F1-F6).
F1 - slot key (blocking, retail). TerrainModernRenderer.DrawLandCells
normalizes every incoming landblockId to (id & 0xFFFF0000u) | 0xFFFFu
before the _idToSlot lookup: the walk hands 0xXXYY0000
(WalkLandBlock.LandblockId) but AddLandblock stores under the DAT id
0xXXYYFFFF (LandblockRenderPublisher.LandblockId) - every walk lookup
was missing and the walk path drew NO terrain. Unit-tested end-to-end
through a real RecordingGpuDevice-backed TerrainModernRenderer
(TerrainWalkSlotKeyNormalizationTests): AddLandblock(0xA9B4FFFF, ...)
is found by a 0xA9B40000 lookup, an unknown landblock is a silent
per-entry no-op, and a batch mixing a known and unknown entry submits
only the known one.
F2 - deferred cross-block batching (blocking, driver). Retail's
DrawSortCell always follows DrawLandCell (LC/SC strictly alternate,
never two LC in a row - S3 section 9 R1), so chunk 3's "merge
consecutive same-landblock LandCell events" rule never actually
merged anything; the driver review flagged batching as inert.
WalkFrameDriver.Replay now keeps ONE pending terrain batch across
landblocks ((landblockId, side, cellIndex) entries, cleared at
Replay's own start); a LandCell event only appends; every OTHER event
kind that will itself submit GPU work (StreamMark, Sky, CellShell,
PunchFan, AlphaBarrier, LandscapeFlush, ClearInteriorDepth,
ExitSeals) flushes the pending batch first; a StaticParticles/
CellParticles turn asks the new ParticleSystem.
HasRenderableEmittersInCell (an allocation-free sibling of
CopyRenderableEmittersInCell) and, when the cell has no renderable
emitter, submits nothing and does NOT flush either - the whole point
of the deferred rule. The end of Replay flushes the remainder. This
is order-preserving by construction: a flush always lands at the
exact point the unbatched draw would have, so GPU submission order -
and therefore pixels - is identical to the unbatched baseline; only
the number of small terrain draw calls shrinks.
TerrainModernRenderer.DrawLandCellRuns becomes DrawLandCells(
viewProjection, IReadOnlyList<(uint LandblockId, int SideCellCount,
int CellIndex)>) - one MultiDrawIndexedIndirect over every entry's
runs, unknown slots skipped per-entry. IWalkFrameLeafRenderer.
DrawLandCellBatch drops its separate landblockId parameter to match
(a batch can span several landblocks now) and gains
HasRenderableEmittersInCell.
Batch-count demonstration: driven through a real WalkFrameDriver
Replay (OnLandCellTurn_MergesAcrossLandblocksOverAnEmptyParticleTurn_
RealSubmissionsSplit), 4 LandCell turns across 3 distinct landblocks,
separated only by an empty particle turn, a real StreamMark, and a
building's alpha barrier, submit as exactly 3 DrawLandCellBatch calls
(2+1+1) instead of 4 - the empty particle turn's non-flush merges two
otherwise-separate cross-landblock entries. At production scale the
same mechanism is expected to cut the terrace-edge frame's ~578
individual DrawLandCell events (S3 section 9's captured transcript
count) to "tens" of submitted batches, per the contract's own
expectation: most terrain cells have no particle owner nearby, so the
strict LC/[empty-SC]/LC/[empty-SC]/... run collapses into one batch
per region bounded by real content (a building, a StreamMark-worthy
cell, or a genuine emitter) rather than per cell.
F3 - per-frame terrain diagnostic (blocking, build/test). The walk
leaf no longer brackets each batch with TerrainDrawDiagnosticsController
.Begin()/Complete() (a per-batch Stopwatch Restart/Stop pair that was
pushing one timing SAMPLE per batch, not per frame).
RetailPViewPassExecutor.DrawWalkLandCellBatch instead times its own
call with a raw Stopwatch.GetTimestamp() delta (no allocation) and
hands the ticks to the controller's new AccumulateWalkBatch;
RetailPViewRenderer.DrawWalkDrivenStatics calls the new
CompleteWalkTerrainFrame() exactly once, immediately after
driver.Replay finishes - "the end of the walk replay", where the
deleted whole-stage terrain leaf's own Begin()/Complete() bracket
used to close - which pushes ONE elapsed-time sample (even a
zero-batch frame pushes a zero sample: one sample per frame, not per
landscape turn) and publishes on the existing 5-second cadence.
TerrainRenderDiagnosticFacts gains a Draws field alongside
VisibleSlots (both were the same field before); TerrainModernRenderer
tracks its own per-frame WalkVisibleSlotCount/WalkDrawCount (a
HashSet<int>/int cleared in BeginFrame, populated by DrawLandCells),
and the diagnostics source reports those whenever the walk drew at
least one batch this frame, falling back to the non-walk Draw()
path's VisibleSlots otherwise (the two paths never both run in the
same frame). The [TERRAIN-DIAG] line's meaning (cpu_us per frame) is
unchanged, so the S3 section 9.5 before/after compare stays valid.
F4 - driver pins for the LandCell position (major). Three RunFrame-
level pins replace the deleted TERRAIN:0 pins: an outdoor-root
sequence (SKY, then one LANDCELL, driving RetailFrameWalk.
DrawLandscape directly with a one-view/zero-vertex WalkPortalView so
WalkLandscape.CheckBlocks' admission stays the same deterministic
"CY-only" test RetailFrameWalkTests already relies on, while still
satisfying WalkFrameDriver's real >=1-active-view fail-loud guard);
an interior-root test with one real exit view and one populated
block (SKY, LANDCELL, LFLUSH, SEALS, SHELL...) built on the existing
RunFrame_InteriorFloodWithExitView_... fixture; and the T4 batching
pin re-expressed for the F2 rule (OnLandCellTurn_
MergesAcrossLandblocksOverAnEmptyParticleTurn_RealSubmissionsSplit,
described above). The fake leaf's DrawLandCellBatch now logs
LANDCELL:<lb>:<side>:<idx>[,...] per batch and gains
HasRenderableEmittersInCell backed by an opt-out CellsWithoutEmitters
set (default true - has-emitters - so every pre-existing pin in the
file keeps its old unconditional-submission behavior unchanged).
F5 - no code change: the walk's in-view gate is unchanged; no
whole-block terrain re-added.
F6 - minor/notes: DrawLandCells' own comment now states the walk's
CheckBlocks/landcell_check admission is the sole terrain culling
authority (retail has no separate terrain frustum test); the
HandleLandscapeTurn comment's inverted claim is corrected (a FARTHER
building's punch survived because NEARER terrain was drawn BEFORE
it, not after - the interleave now draws it after, matching retail);
the "flat/directional-shadow paths" claim is corrected to the one
actual caller, WorldScenePassExecutor.DrawFlatTerrain (a directional-
shadow receiver selects its pipeline inside the SAME DrawRhi call,
not through a second caller); the cathedral order-trace token gains
the LOD side/index (":LC<lb>/<side>:<idx>"); T2's vacuous "no
TERRAIN event" assertion in RetailFrameWalkTests is replaced by a
comment pointing at the F4 driver-level pins; and the stale
"Confirmed OH5 defect" row in oh1-construction-landscape-contract.md
is retired with "FIXED by S3 chunk 3 (commit 671eb3ad4 + fix round
1)".
App hermetic lane: 6,795/6,795 (up from 671eb3ad4's 6,786 baseline -
net +9 tests: 3 F1 slot-key tests, 2 F4a/b driver RunFrame pins, 3
TerrainDrawDiagnosticsController walk-frame tests, plus the T4->F4c
rewrite and the RetailPViewPassExecutorTests split are net neutral).
InstalledDat lane: 241 passed, the same 3 accepted failures (2
pre-existing #383 layout fixture-drift tests, 1 TowerAscent
Status=KnownFailure) - unchanged from baseline. Core Vfx tests:
109/109 (108 baseline + 1 new HasRenderableEmittersInCell lifecycle
pin mirroring CopyRenderableEmittersInCell's own add/move/remove

Three-lens review of 671eb3ad: the terrain slot map is keyed by the DAT id
(0xXXYYFFFF) while the walk passes 0xXXYY0000 (no terrain drawn); the
adjacent-same-landblock batching can never merge because retail's own
DrawSortCell interposes a particle turn after every land cell; the timing
diagnostic moved inside the per-batch loop. Round 1 of two.

- delete the ACDREAM_PROBE_CATHEDRAL_SKIP_SEALS discriminator (member, read
site, launch-options row): its investigation is closed by the retail
axiom, and the review found it had silently gained a second effect through
the seal count (a skipped seal also suppressed the next depth clear);
- the interior PView's draw_landscape is now wired explicitly (RenderDeviceD3D::Init
0x0059efb0), so the two-PView pin asserts wiring, not a default;
- the two backend seam comments name retail's clear gate;
- the counter doc states the Collect/Replay consume/re-arm split and why it
has no retail analogue.

Runs after chunk 3 (LC/SC need per-cell terrain). One print-only flag,
the FW0 parser extended for the OH kinds, the five captures as fixtures
in the existing still-frame conformance harness, and an offline signature

Retail CPU-clips only portal polygons, punch fans and exit seals
(polyClipFinish); ordinary meshes, shells, terrain, particles and the
weather are never view-clipped. Inventory at edb32783: keep the seal and
punch clips (with equivalence pins), delete the per-slice weather loop,
the sky-post-scene particle clip slot, the dead cell-shell clip routing,
the slot-list shape of the part classifier, and the seven
ProbeCathedral* discriminators with their launch-option rows.

GameSky::Draw 0x00506ff0 arg2==1 is the weather pass gated on
SmartBox::is_player_outside 0x00451e80, already modeled by RenderWeather;

Verified against the two cathedral transcripts and the decomp: DrawBlock
0x005a17c0 draws LandCell then SortCell per land cell (alwaysDrawObjects=1,
flush=0.75 makes the per-cell alpha flush inert); the ported ring order,
closest-cell table and ring-to-LOD mapping reproduce every captured LC/SC
sequence at both poses with zero mismatches once LOD cell ids are read as
x*8+y+1 in LOD coordinates; one land cell's terrain is arithmetic on the
existing cell-major 384-index landblock mesh. The interleave is expected to
remove the Holtburg terrain-punch leak by draw order alone (S4 hypothesis);
LScape::draw draws the sky twice (before and after the blocks).

Frame 2 of both cathedral transcripts: one LS, then LC/SC in strict
per-cell alternation, blocks far-to-near with the diagonal interleave
from the Chebyshev-10 ring inward, far blocks at one cell per block, and
SC for all 64 cells of a near block while LC fires only for in-view
cells. This is the interleave chunk 3 ports and the transcript pins.

Decomp-verified during the capture session: PView::DrawCells 0x005a4840
keeps the landscape flush, stamp advance, gated Z clear and exit seals
inside outside_view.view_count > 0; the clear is gated by the persistent
D3DPolyRender::portalsDrawnCount (0x008719b4), which only exit seals feed
in the building path (pass 1 punches pass TRUE; forceClear is never
written). acdream's unconditional clear/seals and the _skyDrawnThisFrame
proxy are the divergence chunk 2 retires. The captures' second PView is
outdoor_pview's look-in flood (RenderDeviceD3D::Init 0x0059efb0).
Also: the cathedral floating-stairs scene row now expects retail's
exterior-slab leak (retail axiom), the retail screenshot is saved at
logs/oh-capture/cathedral-leak.retail.png, and the S3 ledger row moves to
chunk 2 in progress.

Walk (5 frames), parts (3) and alpha-depth (5) transcripts captured from
the paired 2013 client at the owner's cathedral-arrival pose. The live DI
was f4180108 (stair chamber), not the f4180106 the kit README expected
from FW0's still; recorded as-is. A second PView (009d4530, ov=0) draws
f4180112-14 each frame with no DI of its own -- flagged for chunk 2.

Retail-lens review of chunk 6 (no blocking finding). Fixed:
- a cell that gets two object-list turns in one frame (a chamber reached
through two portals) submitted its emitters twice; retail's particle parts
sit in the same shadow_part_list as every other part and CPhysicsPart::Draw's
frame stamp suppresses the second draw, so the walk now dedupes the particle
turn with the same frame-scoped set that dedupes the cell shell;
- every visited land cell paid the full per-cell draw setup even with no
emitter; DrawForCell now returns after the cell lookup, retail's own cost
(DrawPartCell 0x005a07a0 `num_shadow_parts > 0`);
- CopyRenderableEmittersInCell maintains LastRenderScopeEmitterVisitCount;
- the OutdoorSceneParticleEntityIds / outdoorOwnerIds stub chain (permanently
empty, never read) is deleted through IWorldSceneRenderer,
WorldScenePViewRenderer, IWorldScenePasses and the composition root;
- AD-117 item 4 names the two behavioral residuals (owner-cell substitution;
no per-emission AddPartToShadowCells);
- ParticleHookSinkTests pins that an emitter's draw cell is its owner's pose
cell and survives the projection-visibility switch across the per-frame
view pass.

Owner G2 finding: the purple cloud around an arriving character no longer
drew. The server keeps the player Hidden until acdream sends LoginComplete at
reveal completion (retail-correct); the Hidden-state script's emitters spawn
in the arrival cell and are view-eligible when the world appears, but the
walk drew an owner's emitters only through the owner's registry rows, and a
hidden owner's shadow is suspended. Retail's
CPhysicsObj::add_particle_shadow_to_cell (0x00514a70) gives an emitter one
shadow in its OWN current cell, drawn at that cell's turn regardless of the
parent's hidden state (add_shadows_to_cells 0x00514aed skips the flood for
state & 0x1000).
Port: ParticleSystem keeps a per-pass cell -> renderable-handles index
(maintained at every renderable/OwnerCellId change) and
CopyRenderableEmittersInCell; ParticleRenderer.DrawForCell; the walk draws
particles BY CELL at the existing turns (interior CellParticles, landscape
LandscapeCellParticles), the events fire for every visited cell, and every
owner-union particle path is deleted (UnionOwners/UnionNewOwners for
particles, the outdoor drawn-owner dedupe, the executor's owner
classification sets, the context ParticleOwnerIds members). The post-replay
per-cell pass double-submitted the root flood's emitters and is deleted: an
emitter draws once, at its cell's replay turn. AD-117 item 4 becomes a port
note (the index lives in the particle system; an emitter is not a physics
object in acdream). The temporary [pes-spawn]/[pes-vis] traces are removed
and the ACDREAM_DUMP_PLAYSCRIPT row restored.
Verified: timed arrival route logs/selfgate-20260903-062522-haze-chunk6,

Instrumented arrivals show the Hidden-state cloud's emitters spawn in the
arrival cell, become view-eligible when the world appears, and are never
drawn: the walk draws an owner's emitters only through the owner's registry
rows, and a hidden owner's shadow is suspended. Retail's
CPhysicsObj::add_particle_shadow_to_cell (0x00514a70) gives an emitter one
shadow in its own cell, drawn at that cell's turn regardless of the parent's
hidden state. S2 chunk 6 (packet §10) ports that: per-cell emitter draw
membership, owner-union particle path deleted. Route timing fixed so the
arrival screenshots anchor on the reveal.

Owner G2 check at 4b0b29e4: Facility Hub PASS, Holtburg house PASS,
cathedral leak unchanged (S3/S4). Two new findings:
- doorway-sized fragments of houses on the terrace below show through
the hill in Holtburg: PortalDepthMaskRenderer draws every visited cell's
exit-portal fan with depth compare Always + write, so a doorway behind
terrain still punches far depth through it. Pre-existing; S4 owns the
punch (ledger row updated).
- the purple UnHide haze (script type 0x75, played on the retail
Hidden->visible physics-state edge) no longer shows on the local player
after a portal. Under investigation: temporary print-only traces
[pes-spawn]/[pes-vis] under ACDREAM_DUMP_PLAYSCRIPT=1 (launch-options row
amended; both die with the investigation) and a timed arrival route

CObjCell::find_cell_list (0x0052b4e0) with num_sphere == 0 adds only the
current cell — interior CELLARRAY::add_cell at 0x0052b563, outdoor
CLandCell::add_all_outside_cells (0x00533630, the arg2 <= 0 branch:
adjust_to_outside + gid_to_lcoord + add_outside_cell) — and skips the
portal transit walk (`arg4 != 0 && arg2 != 0` at 0x0052b576). So a shapeless
object's transition cell array is its destination cell alone, exactly what
RefreshPositionRows publishes. Not an adaptation; the register row keeps
its three residual readings, the S3 packet drops the capture request, and
the registry/test comments cite the verified function.

connected soak; the gate table names the six S2 commits and the revert rule.

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).

list collision just used, the transition's cell_array retail feeds
add_shadows_to_cells in CPhysicsObj::SetPositionInternal @0x00515330

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

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.
