Ports retail ACRender::polyClipFinish (0x006b6d00, pc:702749) near-eye
semantics into PortalProjection.ProjectToClip - the fundamental fix for
the in-plane portal clip family (climb strobes, tower-top roof/floor
flap while turning; live-corroborated this session: [viewer-diff]
0xAAB30108 strobing 27x mid-climb, whole interior dropping at the top).
Pseudocode: docs/research/2026-06-11-polyclipfinish-w0-clip-pseudocode.md.
Three legs, all decomp-driven:
1. ProjectToClip clips at w >= 0 EXACTLY (was EyePlaneW=1e-4), with
retail's any-negative-w gate. Boundary intersections land at w == 0
(homogeneous directions), so a portal the eye is CROSSING yields the
correct unbounded half-region that the bounded view-region clip cuts
to the screen. A w=0 vertex cannot survive a bounded region clip
into the divide (direction fails some edge of any bounded convex
region); the measure-zero corner case is guarded non-finite->empty.
2. CellView.CanonicalKey keys ALL-COLLINEAR (zero-area) views as their
snapped segment ("L:" + extremes) instead of rejecting them - retail
PROPAGATES degenerate views (ClipPortals decomp:433651-433711
forwards any count!=0 GetClip output, no area gate anywhere), keeping
the cell behind an exactly-in-plane portal in the draw list (cells
draw whole; onward floods die naturally). Rejection dropped the
whole chain for the frame - the parked-eye knife-edge band. Finite
key space unchanged -> dedup + strict-growth convergence intact.
3. The EyeInsidePortalOpening rescue is DELETED (the T2-documented
compensation for the 1e-4 divergence) along with EyeStandingPerpDist
+ PointInPoly2D. Empty clip = no flood, period (retail's rule).
CornerFloodReplay - the gate that REFUTED the previous deletion
attempt - passes WITHOUT the rescue under the W=0 port.
Harness criterion corrected to retail's rules (it codified the rescue):
cells fully BEHIND the camera are not required (all-behind portals clip
empty in retail); monotone area holds per root regime; the two
manufactured exact-on-plane steps assert root-only (boundary root pick
is ambiguous; the in-plane portal there is ~perpendicular to the gaze =
genuinely off-screen). Build_CollapsedInteriorPortalNearEye test
inverted to pin the retail empty-clip rule (it pinned the rescue).
New pins: eye-crossing portal -> w==0 boundary verts + half-region (not
sliver); gaze-along-plane degenerate view accepted + segment-key dedup;
non-finite guard. Replay harnesses (CornerFloodReplay, Issue120,
TowerAscent, HouseExit, Issue127) all green.

The users final broken-state session (user-session-capture2.log,
standing in front of broken stairs) reports meshMissing=0 and
entSeen==entDrawn: the staircase is DRAWN WRONG, not missing. The
handoff records the 8 verified fixes shipped today (none was this bug),
the ranked hypothesis space (H-A hydration-time MeshRef corruption via
SetupMesh.Flatten identity fallback - predicts the barrel IS the
collapsed staircase; H-B Tier-1 partial-batch cache; H-C draw compose),
the decisive one-launch probe design, the polyClipFinish/cdstW port
spec for the climb strobes + top flap (read done, constant pinned), the
apparatus inventory, and the paste-ready pickup prompt.

The users tower capture (tower-viewer-capture.log, 551 [viewer] lines)
decodes into three distinct issues:
- #126 (HIGH, #107/#111 family): an OUTDOOR spawn claim on the tower
roof (z=127.2) is grounded to TERRAIN z=112 - the player is warped
through the roof into the tower interior, outdoor-classified ->
the transparent-interior spawn. The snap outdoor branch must ground
to the nearest WALKABLE surface (roofs/GfxObj floors), not terrain.
- #127 (HIGH, the flap mechanism): per-building flood admissions are
BISTABLE per frame under the outdoor root - flood size oscillates
+-1-3 cells at millimetre eye deltas (45<->52 standing on the roof,
including a byte-static eye flip). Every oscillation = building
interiors dropping in/out -> the roof/edge flap; running past a
building = #123. Interior side shows the same family (flood 1<->3,
outPolys 0<->1 during the climb).
- #128: the staircase was invisible the WHOLE climb under a HEALTHY
interior root (0xAAB30107 FullScreen views - the cone cannot cull a
root-cell static), while the SAME build rendered it perfectly in a
different session (diag spawn + screenshot, meshMissing=0).
Session-sticky nondeterminism; the barrel tracks this bug (a
partial subset of staircase parts), NOT dat content (user axiom:
no barrel in retail). Needs a diag-instrumented repro of the users
session shape.
The [viewer] probe now logs the camera forward (fwd=) so the next
capture can be replayed headlessly - Build clip results depend on the
view-projection, not just the eye.

User verdict on the post-#120 build: "Barrel is gone and more stairs
exist" - the #120 fix partially cured the tower, and the earlier
"legit dat barrels on the landings" claim is RETRACTED (USER AXIOM: the
barrel is NOT in the tower in retail; what the user saw was itself a
render artifact of the corrupted floods, and what the 0x020005D8 cell
statics actually render as is unverified - do not assume barrel).
Remaining tower bugs, both PINNED by TowerAscentReplayTests (the #118
exit-walk pattern, vertical - a helix ascent with the gaze locked ON
the staircase, so a cull has no gaze excuse):
- steps 195-201 (eye z 126.9-127.3, the roof-lip band between the main
cell's ceiling at 126.8 and the roof aperture plane at ~127.2) resolve
OUTDOOR and the per-building exterior flood admits NOTHING (flood=1 =
the outdoor node alone): the eye is above every side aperture's useful
view and ON/INSIDE the roof aperture's plane, so BuildFromExterior's
seed side-test / in-plane reject refuses every exit portal. The tower
interior never floods -> the staircase (a 0x0107 static) cone-culls
while staying walkable (user symptom 1), and the roof-lip cell
geometry flaps as the live eye bobs across the band's edges (user
symptom 2). One mechanism, both symptoms.
- The pin is committed as a SKIPPED red test
(TowerAscent_StaircaseStaysConeVisible_EveryStep; the skip reason
carries the defect) so the suite stays green - un-skip with the fix.
- TowerAscent_RootDoesNotPingPong + the per-step diagnostic stay active.
Fix direction (oracle-first, next): determine which side diverges from
retail - (a) viewer-cell resolution (retail curr_cell may keep the eye
INTERIOR through the band: keep-curr above open-top cells / cell BSP
classifying the parapet bowl as inside 0x010A, where our resolution
demotes to outdoor), or (b) exterior seed admission (retail
ConstructView(CBldPortal) Sidedness with an in-plane eye). Grep the
named decomp for both before touching either layer.

The in-tower ACDREAM_WB_DIAG launch (the saved character spawns inside
the #119 tower - a free deterministic repro lever) produced the
mechanism evidence in one run (tower-wbdiag3.log):
1. [wb-error] upload of 0x0100321D died on a GL InvalidOperation in
ManagedGLTextureArray..ctor (new TextureAtlasManager) - caught,
returns null, and the drop is STICKY: _preparationTasks.TryRemove
runs BEFORE the upload, so a failed upload is never re-prepared.
Permanently invisible mesh, one log line. This failure class is the
likely #119 missing-stairs mechanism (dat + extraction +
registration + dispatcher all exonerated by read/test this session).
2. The SAME GL error then fired UNCAUGHT in Tick -> GenerateMipmaps ->
ProcessDirtyUpdatesInternal and killed the process. Both render-
thread - not thread affinity. Filed as #125 (HIGH) with the open
question of GL error attribution (a stale error queued by an earlier
unchecked call lands on WB's diligent glGetError checks).
Also fixed here: WbDrawDispatcher.MedianMicros crashed with
IndexOutOfRange on the first diag flush when exactly 1 sample was
recorded (copy[copy.Length - nz/2] with nz==1) - the same off-by-one
GameWindow's TerrainDiagMedianMicros twin fixed; same fix applied.
ACDREAM_WB_DIAG=1 is usable again.

Fix: dynamics' ATTACHED emitters (portal swirls on server-spawned portal
entities, creature effects) fell through EVERY particle filter under the
unified pview path - the landscape slice filter carries outdoor statics
(+ the #118 outside-stage dynamics), the per-cell callback carries cell
statics, and T4 deleted the clipRoot==null global pass from normal
frames. T5 never checked portals; the user's re-gate caught it ("all
portals that were previously showing are now gone"). DrawDynamicsLast
now hands its cone-surviving dynamics (minus outside-stage entities,
whose emitters already drew in the landscape slice - alpha particles
must not double-draw) to a new DrawDynamicsParticles callback;
GameWindow draws Scene-pass emitters filtered to those owner ids,
mirroring DrawRetailPViewCellParticles. Retail shape: emitters draw
with their owner object.
Re-gate ledger (user verdicts are axioms):
- #117 CLOSED ("Yes solved"), #118 CLOSED ("Yes solved" + NPC-through-
door "Yes fixed").
- #108 REOPENED narrowed: cellar-ascent eye-below-grade window only
(grass covers the exit door until the head pops over ground level);
fix belongs on the membership/viewer side - the depth-gated punch
stays (DO-NOT-RETRY).
- #119 user split: phantom walkable stairs at the hill cottage (#113
family), tower missing stairs + barrel (#119 proper), hill-house
transparent-on-entry (#112 - re-check after the #120 fix; the
ping-pong fired at exactly A9B3 0103/010F).

- NEW #122 window oscillation on entry (re-check after #120 first),
NEW #123 buildings transiently disappear running close past,
NEW #124 far-building back walls missing through openings (lead:
per-building look-in floods run only for outdoor roots -
NearbyBuildingCells is null for interior roots; retail runs the

Issue119UpNullGfxObjDumpTests pins the dat truth: 0x010002B4 = 9 polys,
ALL NoPos, all surfaces Base1Solid; 0x010008A8 = 1 poly, NoPos,
Base1Solid|Translucent. Retail's skipNoTexture never draws either model
(the BR-1 build-time-skip <=> draw-time-skip equivalence), so
ObjectMeshManager's empty render-data cache is the CORRECT terminal state
- the only defect was the alarming "permanently invisible" log line,
reworded into an honest tripwire pointing at the dump test.
Second fact, same test (ShellModel_NoTexturedPolyIsDropped): on the
hall/tower shell 0x010014C3, ZERO textured polys are dropped by the
extraction gates (137/149 draw; the 12 dropped are the known #113
no-draw orphans) - the per-poly GfxObj extraction is exonerated for
building shells, kept green as a regression pin.
Net for #119: the missing tower-stair parts are NOT the up-null pair and
NOT a per-poly extraction drop. Remaining hypothesis space (interior
stair-cell flood admission, or a different model than assumed) needs the
re-gate to identify the exact tower; then the cell set + flood replay
headlessly like #118. ISSUES.md updated.

Root cause (pinned by the new deterministic exit-walk harness, NOT guessed):
under an interior render root, the exit-portal SEAL stamps the door fan at
TRUE depth after the gated full depth clear, and T1's "ALL dynamics last"
pass then drew the outdoor-classified player depth-tested - every fragment
beyond the door plane z-failed against the seal across the whole aperture.
Harness measured the full window: from the moment the sphere center crosses
the plane until the eye follows (~2.6 m of camera lag, ~2.2 s at walk speed)
the player is invisible; while straddling, the beyond-plane body half clips
at the plane. The handoff's three cone-level candidates are all EXONERATED:
the cone walk passes every step; (eye, ViewerCellId) come from the same
SweepEye call with camera-update-before-visibility-read in the same frame;
the side-test window is sub-epsilon under healthy resolution.
Retail oracle (grep-named-first): PView::DrawCells 0x005a4840 runs
LScape::draw FIRST (pc:432719), then the gated depth clear (pc:432731-32)
and the exit-portal seals (pc:432785-86); outdoor cell objects draw inside
the landscape stage (DrawBlock 0x005a17c0 -> DrawSortCell pc:430124), and
an object draws once per overlapped shadow cell (pc:430056-64) - the
straddling body composes from both stages, neither half clips.
Fix: RetailPViewRenderer assigns dynamics to the OUTSIDE stage under an
interior root when outdoor-classified OR sphere-straddling an exit-portal
plane of their flood-visible cell (DynamicDrawsInOutsideStage - pure, the
harness drives it as the ordering contract); they ride the landscape slice
draw (pre-clear, seal-protected) with the same per-slice cone test as
outdoor statics. Indoor dynamics keep the last pass (retail loop C);
straddlers draw in both (retail shadow dual-draw). Outdoor roots keep
all-dynamics-last - the BR-2 punch-after-dynamics lesson (88be519) stands.
Apparatus: HouseExitWalkReplayTests - dat-backed corner-building exit walk
driving the production stack headlessly (RetailChaseCamera damping ->
healthy-sweep viewer resolution -> PortalVisibilityBuilder.Build ->
ClipFrameAssembler -> ViewconeCuller -> the DrawDynamicsLast predicate +
a CPU seal-depth model). 5 tests: cone pin, seal-depth pin, straddle

Read-level exonerations: the local player routes to Dynamics correctly
(ServerGuid set), and its entity ParentCellId syncs per tick from the
controller - neither is the vanish mechanism. Live candidates are the
doorway-crossing decision stack: (a) eye/cell incoherence under camera
damping (the verified #115/BR-8a divergence - we damp from our own
damped eye while the root comes from the swept cell), (b) the
exit-portal side test culling the OutsideView when the eye is
epsilon-outside while the root is still interior (retail's
AdjustPosition demotes the viewer cell the same moment), (c) the
aperture-cone tightness for an outdoor player with an indoor viewer.
Next step is the deterministic exit-walk harness (all-CPU drive of the
production decision stack over the corner-building cells); designed in
the issue entry, queued for a focused session.

Investigation: retail's growth propagation RECURSES natively too
(AddViewToPortals -> FixCellList -> AdjustCellView -> AddViewToPortals,
Ghidra 0x005a52d0/0x005a5250/0x005a5770, no depth guard) - the in-place
recursion shape is faithful; retail's safety is fast convergence. Our
depth-128 firing means slow/non-saturating growth (each lap of a portal
cycle nests one recursion level), not necessarily a true infinite loop.
Two dat-backed sweeps over the corner-building cell set could NOT
reproduce the T5 firing:
- PortalPlaneCrossings_InPlacePropagationConverges: +/-6cm eye sweep
across every portal plane, seeded from both sides.
- InCellDirectionSweep_InPlacePropagationConverges: 3024 builds, in-cell
eye grid x 8 yaw x 3 pitch (the walking-and-turning regime).
Both pass with 0 firings -> production-only ingredients suspected (full
lookup graph - one T5 firing was 0x0162, another building - and/or the
real camera path).
Armed: PortalVisibilityBuilder.ConvergenceTripwireCount (test
observable, both Build + look-in sites) + DumpPropagationChain - on the
next firing the log carries root cell, eye, per-cell frequency summary,
and the 24-entry chain tail, so the cycle's structure (A<->B ping-pong
vs 3-cycle laps) reads directly off the output. Both sweeps stay as
regression pins.
App tests: 227 green (was 225; +2 pins).

The A6.P4 port, fused into one installment per the BR-2 half-port lesson
(registration and query are co-dependent: flood-registering shells under
the old radial query would re-open #98 through the vestibule).
REGISTRATION (ShadowObjectRegistry rewritten):
- Register/RegisterMultiPart/UpdatePosition compute the cell set via
CellTransit.BuildShadowCellSet (the C2 find_cell_list flood) seeded by
the entity's m_position cell id; the private 24m XY-grid rectangle and
its single-landblock clamp are deleted. Flood spheres follow retail's
CylSphere rule (base point + cyl radius, cap 10; BSP bounding-sphere
fallback - Ghidra 0x0052b9f0). Statics flood with the do_not_load
prune; dynamics (server spawns, isStatic:false) without.
- Keep-when-empty (SetPositionInternal num_cells gate, pc:283540): a
failed flood leaves the previous registration in place.
- RefloodLandblock: streaming-race hook re-runs the flood when a
landblock's cells hydrate (retail init_objects -> recalc_cross_cells,
Ghidra 0x0052b420/0x00515a30); wired at GameWindow's hydration tail.
- GameWindow sites pass the server position's full cell id as the seed
(spawn + UpdatePosition); the five static sites pass ParentCellId.
BUILDING CHANNEL (CSortCell.building shape):
- Building SHELLS are not shadow objects in retail (only caller of
find_building_collisions is CSortCell::find_collisions 0x005340aa;
one building per origin landcell, init_buildings 0x0052fd80 verified
verbatim + ACE cross-ref). IsBuildingShell entities skip the registry;
Transition.FindBuildingCollisions runs the shell part-0 BSP off
cache.GetBuilding(cellId) with bldg_check set around it
(find_building_collisions 0x006b5300), CollidedWithEnvironment on
non-Contact non-OK. BuildingPhysics.ModelId = pre-resolved part-0
GfxObj (0x02 Setups resolved at the CacheBuilding site).
- Placement/ethereal weakening: BSPQuery Path 1 passes center_solid=0
when BldgCheck && HitsInteriorCell (BSPTREE::find_collisions 0x0053a82e
+ placement_insert 0x005399d8) so doorway crossings don't hard-fail
against shell solids. SpherePath gains both retail fields;
HitsInteriorCell is rebuilt at every cell-array build
(build_cell_array reset 0x00509ef2 + find_cell_list/check_building_
transit set sites).
QUERY (retail per-cell order, transitional_insert 0x0050b6f0):
- TransitionalInsert per attempt: env -> building (LandCell only) ->
objects on the PRIMARY cell, then on OK the check_other_cells pass
(env -> building -> objects per OTHER overlapped cell) + the
carried-cell advance - the advance now happens AFTER all per-cell
object passes (the WF1 ordering divergence), with Adjusted/Slid
feeding the retry exactly like retail's OK_TS case.
- FindObjCollisionsInCell = CObjCell::find_obj_collisions (0x0052b750):
iterate ONLY the asked cell's list. DELETED: the radial 9-landblock
sweep, the +5m query pad, the b3ce505 indoor-primary gate, and the
isViewer exemption (the camera is bounded by interior cell-BSP env
collision - retail's own channel; CameraCornerSealReplayTests pins it
against real dat, and the new building-channel camera test pins the
outdoor stop).
TESTS: Core 1416/0/2 (was 1398 + 4 pre-existing #99-era fails + 1 skip),
App 225, UI 420, Net 294 - all green.
- 3 of the 4 #99-era reds flipped green as designed: the door apparatus
(Apparatus_Grounded_50cmOffCenter_FrontApproach_Blocks) and tick-13558
(indoor walkthrough) now assert the door BLOCKS; tick-22760 pins the
outdoor blocking invariant.
- The 4th (BSPStepUp D4) + 22760's lateral-slide delta are NOT cell-set
problems (probes prove the door is found + BSP-only dispatched;
BR-7 left both byte-identical) - filed as issue #116 (slide-response
family), D4 skipped with the issue reference.
- FindEnvCollisionsMultiCellTests migrated to the public entry (the A4
multi-cell halt now lives at the retail call site).
- New registry pins: per-cell query surface, outdoor-footprint-never-
indoor (#98 architectural), door-outdoor-cell membership, reflood.
- CameraCollisionIndoorTests rewritten against the building channel
(the isViewer-exemption pins died with the exemption).
Closes#99 (doors block both ways via registration-time cell membership
+ the straddle-spanning player cell array). #97 likely closed (the +5m
radial pad that produced phantom-collision candidates is gone) - verify
at T5. #98 stays closed ARCHITECTURALLY (outdoor footprints structurally
cannot reach interior cells; the cellar harness stays green).

Doc-and-reality sync before the session handoff: the plan's phase
sections read future-tense while T1-T4 landed them. The render digest
carries the authoritative ledger; this stamp points there and names the
4 pre-existing #99-era Core failures as BR-7's built-in acceptance
signal.
'I don't care if it is non-playable... I want everything ported, then we
test.' Per-phase playability + per-phase visual gates DROPPED. BR-2..BR-6
execute as ONE continuous port with build+tests green per commit and a
single comprehensive visual pass at the end (T5). Replaces the
playability rule with: every installment must be a COMPLETE retail
behavior, never half of one (the BR-2 punch-without-ordering lesson,
88be519).
The BR-2 punch/seal gate proved #108 (cellar grass-sweep) is a membership
flip (player classified outdoor mid-cellar), not a render depth bug. The
punch only masked it on outdoor-root frames. Move #108 to the membership
track; the interior depth seal is a separate mechanism that does not fix it.
The plan's BR-1 ('implement the skipNoTexture draw-time surface gate')
died on its pre-check: acdream ALREADY suppresses every portal fill.
ReplicateProductionEmission_OnPortalFills replicates the exact emission
conditions of the production extractors on the hall/cottage fills:
pos=False neg=False for every one (Stippling.NoPos skips the positive
side at ObjectMeshManager.PrepareGfxObjMeshData:1046,
PrepareCellStructMeshData:1394, CellMesh.Build:44, GfxObjMesh.Build:71;
the fills have no negative surface). There is nothing to gate.
What ships instead: StipplingSurfaceEquivalenceTests - 2,607 polys across
13 building models + 13 environments, ZERO violations both directions:
NoPos <=> untextured-surface. Our build-time skip is proven equivalent to
retail's draw-time skipNoTexture rule (Ghidra 0x0059d4a4, default on
@0x00820e30) on this content. The pin fails loudly if future content
breaks the invariant - the cue to implement the draw-time gate then.
Corrections folded into the plan + comparison docs:
- The #113 phantom residual CANNOT be GfxObj fills (they never reach a
vertex buffer). Plausible true sites are cell-side: flood-admitted
cells drawn with the pass-all NoClipSlice when slot-less
(RetailPViewRenderer.cs:71), and/or cell statics drawn unclipped +
un-viewcone'd (object-lists-skip-portal-view-gate, confirmed).
BR-2 opens with the probe that pins which.
- The e46d3d9 user-gate observations (filter removed phantom/doors) were
confounded - the filter was a provable mesh no-op on shells AND doors.
- Ledger rows solid-surface-skip-missing + the acdream half of
portal-polys-baked-unconditional re-marked REFUTED-for-fills; the
retail mechanism descriptions and the un-consumed PortalIndex->
CBldPortal pairing (BR-4) stand.
Suites: Core 1398 green (1392 baseline + 6 new facts) + the 4 pre-existing
#99-era failures + 1 skip. No production code.

Headline findings: (1) retail flattens GfxObjs/cells at load exactly like
us (ConstructMesh + RemoveNonPortalNodes) - the MDI pipeline survives;
(2) the phantom/door mechanism is the skipNoTexture draw-time surface gate

aperture exactness is a DEPTH discipline (punch maxZ1 / seal maxZ2 / gated
clear + far-to-near whole-mesh draws) - reframes #114; (4) flood admission
is already faithful, the trigger/depth/multi-view/cone-culling layers are
missing; (5) #115 root cause verified (boom damping severed from the
published collided viewer); collision A6.P4 design verified with

#113 moved to Recently closed: the phantom staircase was the Holtburg
meeting hall (AAB3, not A9B3) interior stair cells drawn unclipped from
outside - the PView shell clip was routed but never GL-enabled (927fd8f).
Misplaced-cell hypothesis refuted with dat evidence. #112 residual
paragraph updated: retail straddle gate live-binary verified + ported
(414c3de); at-doorway demote is retail-faithful, deep gaps now keep-curr.

The 137b4f2 payload, re-landed now that #110 is resolved: the missing-indoor-
textures correlation was the pre-existing #105 staged-texture-flush drop
(fixed in c787201), not a near-plane mechanism. znear=0.1 merely raised #105's
trigger probability — a closer near plane makes close-up geometry newly
visible, inflating per-frame prepare/upload pressure indoors and growing the
never-flushed tail. Exactly the handoff's only-credible-link hypothesis,
verified instead of assumed.
Retail: Render::SetFOVRad sets znear=0.1 flat (decomp :342173, initializer
:1101867). 0.1 < the 0.3m camera-collision sphere, so a wall the collided eye
presses against no longer falls inside the near plane — the §4 corner
see-through-wall closes.
Verification on the 0.1 arm (the arm that struck 2-of-3 on 2026-06-10):
nearplane-reland-1.log — [tex-flush] after=0 on all 45 lines, 68,291 [shell]
lines with zero zh>0 batches, all four dat tripwires silent, no [wb-error].
ISSUES.md: #105 + #110 moved to Recently closed with root cause + evidence.
Pending user re-gate: corner press (wall stays solid) + distance scan for
z-shimmer (none expected; retail ships 0.1 with D24).

Bisect (user-gated): two consecutive runs on 0.1 lost indoor textures; the 1.0 bisect run rendered clean. #105 tripwires silent on the bad runs (GL-side). No known mechanism links the near plane to texturing - #110 filed to investigate (RenderDoc / flip-testing) before re-landing retail's znear=0.1, which the corner see-through fix depends on. Comments on all four cameras point at #110 so the retail value is not re-landed blind.

The collided camera eye sits 0.3m from walls (viewer_sphere radius); a 1.0m near plane clipped the wall face away, so pressing the camera into a corner showed the clear color through the wall (gate result: unchanged by the flood fix - it was never a flood bug). Retail sets Render::znear = 0.1 flat in SetFOVRad (decomp :342173, initializer :1101867). All four cameras aligned. Also files #107 (indoor spawn wedge, 3-for-3), #108 (cellar-up terrain sweep across door opening), #109 (exit-door texture/background oscillation) from the 2026-06-10 visual gate; gate confirms the dac8f6a flood fix: room-room + indoor-outdoor transitions clean.

Move #106 to Recently closed (user-verified collision + solid walls;
probe-verified 49 clean transitions incl. south A9B4->A9B3 at y=-0.19,
east A9B3->AAB3 at x=192.2, and room-by-room tracking through the
originally-failing A9B3 cottage). Records the three adjacent
pre-existing bugs the gate runs surfaced and fixed (legacy Resolve bare
ids, bogus-indoor-claim recovery, entry-hold streaming deadlock).
Correct the capture doc's attribution: the outdoor running distortion
was NOT fully the stale anchor — gate 4 shows residual background-color
screen artifacts persist with a correctly-following anchor. The
residual is the render §4 flap family (render digest), not membership.

The #106 live gate run was sabotaged by a pre-existing bug the corrective
ACE teleport exposed: PhysicsEngine.Resolve (the legacy Phase-D resolve,
still used by the teleport-arrival snap at GameWindow.cs:4869 and the
player-mode-entry snap at :11295) returned BARE low-word cell ids on
every computed exit (ComputeOutdoorCellId, bestCell.CellId & 0xFFFF,
nextCellIndex, enterCellIndex). The teleport committed 0x0000013F into
PlayerMovementController.CellId, and a bare indoor id wedges the entire
membership chain:
- GetCellStruct(0x0000013F) misses (cells are keyed full-prefix) -> no
indoor wall BSP -> walk through walls;
- the b3ce505#98 gate reads "indoor primary" -> outdoor object radial
sweep skipped -> NO object collision anywhere in the world;
- BuildCellSetAndPickContaining early-returns an unresolvable id forever
(block 0x0000 is a real far-NW map block) -> membership frozen;
- render root never resolves -> interiors draw empty when stepping in.
Probe evidence: probe-cell-106-gate.log has exactly 2 [cell-transit]
lines for the whole session, both reason=teleport — the second one
(0xA9B3003C -> 0x0000013F) is the wedge. This is the L.2e "player CellId
tracked as bare low byte" finding (2026-05-12) finally biting; prefix
survival until now was a race artifact — Resolve only preserved the full
id when the landblock had not streamed in yet (passthrough exit), which
is why login snaps usually came out prefixed.
Fix: capture the matched landblock's key in Resolve's containment loop
and return lbPrefix | (targetCellId & 0xFFFF) on the computed exit —
the same full-32-bit convention Resolve's own doc comment states for
its inputs, and what both production callers (player snaps) require.
The passthrough exits (no landblock / step-reject) still return the
caller's id unchanged.
Tests: Resolve_IndoorStay_ReturnsFullPrefixedCellId (the teleport
shape, red pre-fix) + Resolve_OutdoorStay_ReturnsFullPrefixedCellId;
Resolve_LeaveIndoorCell_TransitionsToOutdoor's unmasked
`CellId < 0x100` assertion codified the bare behavior — now masked +
asserts the prefix. Full suite: 294+218+420 green; Core 1371 green +
the same 4 pre-existing door/#99-era failures + 1 skip.

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

The 53MB flap-probe capture (user live-reproduced the broken-house entry)
plus 3-agent analysis settles the day: playerCell froze at 0xA9B40031 for
10,449 frames spanning ~130m of outdoor walking into landblock A9B3 and a
stand INSIDE an A9B3 cottage. Within-landblock outdoor flips are 96/96
clean; all 10 successful indoor entries were same-landblock buildings; the
single cross-landblock entry failed. The render flood independently drew the
A9B3 interior cells the whole time — rendering is downstream and healthy;
membership is the broken layer (feedback_render_downstream_of_membership,
proven again). The stale render anchor also explains the outdoor running
distortion; the capture refutes flood-level causes outdoors (26,960/26,960
outdoor frames rigid at outPolys=1 vis=1).
Files #106 (HIGH, physics/membership) with fix pointers: ResolveCellId /
AddAllOutsideCells cross-landblock proposal, the b3ce505 outdoor-sweep gate
(possible stopgap fallout, like #99), retail find_cell_list :308742 +
LandDefs.get_outside_lcoord. Reframes #105: largely superseded by #106;
residual (single wall missing while membership indoor-correct) stays open
with all tripwires armed. Handoff:

Records the 2026-06-09 dat-reader thread-safety investigation: concurrent
READS on Chorizite.DatReaderWriter 2.1.7 exonerated (source audit + 1.1M-read
hammer, b3920d8); the real crash was dispose-during-read at teardown (fixed,
8fadf77); the white-walls mechanism remains open as #105 with every silent
dat-miss exit tripwired (7433b70) so the next occurrence self-attributes.
Also corrects project lore: the A.1-era rule that all dat reads must stay on
one thread does not hold for the 2.1.7 read path, and both investigation
subagents'' claimed ReadBlock instance-field race does not exist in the
shipped source — verify agent claims against source before acting on them.

R-A2b (485e44d) killed the 0171<->0173 churn (maxPop 16->1, measured). Visible flap residual is sec 4 (edge-on openings render-side + corner camera-seal). Camera-damping tried+failed+reverted. The white-walls scare was a RED HERRING: heavy per-frame probes (ACDREAM_PROBE_FLAP) starve the thread-unsafe dat-reader so texture-decode loses the race -> white; a clean launch (no probes) fixes it. The dat-reader thread-safety bug is the real underlying issue (filed). Repo clean at HEAD.

Reading retail InitCell (:432896) side test during writing-plans showed retail's flood is acyclic (the back portal fails the side test, so 0171<->0173 can't cycle). Our flood traverses the back portal -> the cycle -> the churn. Option B (user-chosen): cull the back portal like retail, keep the forward-portal void rescue, remove the dead cap. Phase 1 pins WHY the back portal is traversed (B1 eyeInsideOpening bypass vs B2 CameraOnInteriorSide convention) before the fix; spec REVISION updated A->B.
