Integrates main's 19 commits (A7 outdoor/indoor torch lighting Fix A/B/C/D,
GlobalLightPacker, shader updates, UN-7) under the D.5 toolbar/item-model stack
(D.5.1/D.5.2/D.5.4/D.5.3a). Auto-merged cleanly except docs/ISSUES.md.
Conflict resolved: both lineages used #140 for different issues. Kept main's
#140 = "A7 Fix D" (resolved); renumbered the toolbar/selected-object issue to
#141 (note added; this branch's commits/spec still reference #140 — immutable).
The register auto-merged (AP-46 cites file:line, not #140; UN-7 keeps #140=Fix D).
Build + full suite green on the merged tree (2,713 passed / 4 skipped).

Resolves the divergence-register conflict: kept the accurate per-VERTEX AP-35
(Fix A shipped per-vertex; main's row was the stale pre-Fix-A per-pixel text),
kept main's UI rows AP-37..AP-42, and renumbered this branch's torch-gate row
AP-37 -> AP-43 (AP-37 was taken by main's LayoutDesc row). AP count 41 -> 42.
Retargeted the AP-37 references in WbDrawDispatcher + the CHECKPOINT to AP-43.
Marked ISSUES #140 RESOLVED (b7d655b) with the corrected root cause.

The Holtburg meeting-hall facade washed out warm/bright vs retail. The round-1
checkpoint blamed torch REACH (acdream Falloff 6×1.3=7.8m vs a supposed retail
Falloff 4). That theory is WRONG, and this commit fixes the real cause.
Empirical (HoltburgTorchFalloffProbeTests, headless dat dump via the production
LightInfoLoader): the orange entrance torch (setup 0x020005D8) is raw dat
Falloff 6 and acdream reads it FAITHFULLY — there is no Falloff-4 torch anywhere
in Holtburg. Both clients read the same dat float, so reach was never inflated.
Decomp (read verbatim + corroborated by an independent adversarial workflow):
retail's per-object torch binder minimize_object_lighting (0x0054d480) is gated
in RenderDeviceD3D::DrawMeshInternal (0x0059f398) by `if (Render::useSunlight == 0)`.
The outdoor landscape stage runs useSunlightSet(1) (PView::DrawCells 0x005a485a,
before LScape::draw), so the building EXTERIOR shell — drawn via
DrawBlock→DrawSortCell→DrawBuilding→CPhysicsPart::Draw→DrawMeshInternal — is lit
by SUN + ambient ONLY; torches are SKIPPED. The static bake
(SetStaticLightingVertexColors 0x0059cfe0) is EnvCell-only. So retail NEVER
torch-lights outdoor objects. This exactly explains the isolation test (object
point lights OFF → building matches retail).
Fix: WbDrawDispatcher.ComputeEntityLightSet gates per-object torch selection on
the object being INDOOR (ParentCellId is an EnvCell, (id&0xFFFF)>=0x0100) via the
pure predicate IndoorObjectReceivesTorches. Outdoor objects (building shells with
null ParentCellId, outdoor scenery, outdoor creatures) keep the all-(-1) light
set ⇒ sun + ambient only = retail. The indoor "no sun" half is already handled by
the global sun-kill when the player is inside a cell (UpdateSunFromSky). No
dungeon regression: EnvCell statics get ParentCellId set (keep torches).
Divergence register: AP-37 (residual: acdream keys sun/torch on the object's own
cell + a per-frame player-inside sun-kill, vs retail's per-draw-stage useSunlight;
only matters for through-doorway look-ins). The round-1 CHECKPOINT got a RESOLVED
banner correcting the reach theory.
Tests: WbDrawDispatcherTorchGateTests (7), HoltburgTorchFalloffProbeTests (dat
dump). App 280/1skip, Core 1486/2skip green. Held at the visual gate — not merged.

Same-instant cdb proved acdream ambient (0.447) == retail (0.4465) and time/sun match,
so the building/character over-brightness is NOT the bake/wrap/EnvCell/clamp (D-1..D-4,
all correct but off-target) — those light the wrong surfaces. The Holtburg building
exterior is a mode-0 OBJECT (IsBuildingShell, not an EnvCell). Isolation (object point
lights gated OFF) made it match retail => cause is the torch REACH being too long
(acdream range 7.8 = Falloff 6x1.3 vs retail 5.2 = Falloff 4x1.3), flooding the small
facade. OPEN: confirm same-torch Falloff acdream-vs-retail before tightening the reach.
Diagnostic shader hack reverted (tree clean); D-1..D-4 kept. Branch not merged.

Resolve the Fix D contradiction with decomp (workflow wf_f660eb88 + adversarial
verify) + 4 live cdb captures. The D3D-FF model was the WRONG oracle: retail has
TWO light systems — STATIC torches BAKE into wall vertices (calc_point_light,
triple-clamped: range gate + per-channel min(scale*color,color) + per-vertex
[0,1] from black), DYNAMIC lights go D3D hardware. The captured intensity=100 is
the purple PORTAL (magenta, dynamic), not a wall torch. Ground truth: 38 static
warm torches (orange (1,0.588,0.314)/cream, intensity=100, falloff 3-5) + 2 dynamic.
acdream over-brightness = two confirmed bugs: D-1 mesh_modern.vert folds
ambient+sun+torches into one UNCLAMPED accumulator (single frag clamp) -> warm
blowout; D-2 EnvCellRenderer never binds SSBO 4/5 so the cell shell reads a leaked
light set. Spec: D-1 in-shader clamp-split (clamp the torch sum on its own before
ambient/sun); D-2 bind the shell's own per-cell light set (mirror WbDrawDispatcher);
LightBake.cs is the C# conformance oracle. Adds the 4 reusable cdb capture scripts.

Frames the root cause of the live-Coldeve 4/6-missing-hotbar-icons (acdream's
enrich-existing-only item model drops CreateObjects without a pre-seeded stub) and
the retail ClientObjMaintSystem model to port. CRUX to settle first: unify the

Research basis (clean Ghidra decompile via MCP + live-dat probe + ACE oracle)
overturns two handoff hypotheses:
- Appraise carries NO icon/UiEffects data (Icon/IconOverlay/IconUnderlay +
PropertyInt.UiEffects all lack [AssessmentProperty]); every icon input is
CreateObject-only. The "wire appraise -> enrichment" item is a no-op.
- The effect overlay (enum 0x10000005) is a ReplaceColor tint SOURCE, not a
blit layer (RenderIcons 0x0058d180 + ReplaceColor 0x00441530); effect tiles
are 32x32 fully-opaque colored squares.
Design (user-approved): capture UiEffects (weenieFlags 0x80, currently discarded)
-> ItemInstance.Effects; faithful 2-stage IconComposer recolor (white pixels ->
effect hue); live PublicUpdatePropertyInt(0x02CE) wire-up so the icon updates as
state changes ("item with mana vs out of mana"). Drops the appraise no-op.

Extensive handoff for the next session to build the full stateful item-icon system (the 5-layer IconData::RenderIcons composite + effect layer 0x10000005 + overlay ReplaceColor tint + appraise-driven enrichment/re-composition).

Five report-only deep-dives + synthesis for the next D.2b UI panels, built on the shipped widget toolkit. Confirms LayoutDesc ids (toolbar 0x21000016, inventory 0x21000023, backpack 0x21000022, paperdoll 0x21000024, 3ditems 0x21000021), the shared item-slot/item-list spine (UIElement_UIItem 0x10000032 / UIElement_ItemList 0x10000031), the 5-layer icon composite (IconData::RenderIcons @407524), the cross-panel wire catalog with acdream parse-status, and the dependency-ordered build plan.

ToAnchors was inverted vs retail UIElement::UpdateForParentSizeChange @0x00462640:
stretch is RightEdge==1 (not ==2/==4), LeftEdge==2 = track-right. Verified against
all 19 vitals fixture pieces. Enables Resizable/ResizeX on the importer vitals root
(the prior 'dat is fixed-size' conclusion was wrong). At-rest render unchanged
(anchors only fire on resize). Added a 160->200 resize conformance test.
Also fixed DatWidgetFactoryTests.RectAndAnchors_SetFromElementInfo which encoded
the old inverted model (Right=2 expecting Right anchor; corrected to Right=1).

main was 65 commits ahead of this branch's fork point. Only conflict was the

main's AP-32..AP-36 (cell-shell lift, look-in cells, alpha deferral, dungeon
streaming, point lights) and renumbering the importer's row to AP-37; AP header

Process/quality items from the LayoutDesc-importer final review — no runtime
behavior change.
I1a — amend IA-15: the 8-piece chrome edge/corner→position mapping is no longer
a guess. The LayoutImporter (ACDREAM_RETAIL_UI_IMPORTER) reads real LayoutDesc
dat data and resolves positions + sprite ids directly; locked by the conformance
fixture vitals_2100006C.json. Residual risk trimmed to anchor resolution at
non-800×600 + controls.ini cascade. Pointers added to LayoutImporter.cs and the
format-doc.
I1b — add AP-32: the importer collapses the dat's nested meter structure
(Type-7 → two Type-3 containers → three image-slice grandchildren each) into
UiMeter's programmatic 3-slice fields instead of building those nodes generically
and porting UIElement_Meter::DrawChildren. Standalone Type-0 text elements are
also skipped (Plan 2). Retail oracles: UIElement_Meter::DrawChildren @0x46fbd0,
UIElement_Text::DrawSelf @0x467aa0.
I1c — AP section header 31 → 32.
N1 — ElementReader.cs: comment at the Type-merge line explaining that a derived
Type 0 (text element) inherits the base's Type 12 (style prototype), which
DatWidgetFactory skips; safe for Plan 1 because vitals numbers render via
UiMeter.Label. Format-doc §10: correct the "render as UiDatElement" sentence to
"skipped entirely" (Type-0 → inherits Type-12 via Merge → factory returns null).
N4 — new conformance test VitalsTree_TextLabel_InheritsFontDidFromBaseLayout:
walks the raw ElementInfo tree from the fixture and asserts at least one element
carries FontDid==0x40000000, proving Resolve()'s inheritance merge fired against
real dat data. FixtureLoader gains LoadVitalsInfos() that returns the raw tree
without calling Build.
Tests: 36 pass (was 35), 0 errors, 0 warnings.

Resolves all 6 open unknowns for Tasks 2–6 of the LayoutDesc importer plan:
1. Edge-anchor flags: 1=near-pin, 2=far-pin, 3=float-center, 4=stretch.
The plan's assumption of 4="pinned to that side" is corrected — 1 is
the near-pin, 4 is stretch (both sides). Revised ToAnchors signature given.
2. ElementDesc members: all are public FIELDS (not properties). X/Y/Width/
Height/LeftEdge/etc. are uint. Type is uint (not enum). States is
Dictionary<UIStateId, StateDesc>. Children is Dictionary<uint, ElementDesc>.
3. StateDesc shape: Properties is Dictionary<uint, BaseProperty> with concrete
subclasses (ArrayBaseProperty, DataIdBaseProperty, IntegerBaseProperty, etc.).
Font DID (0x1A) is ArrayBaseProperty[ DataIdBaseProperty{Value=0x40000000} ].
Font color (0x1B) is ArrayBaseProperty[ ColorBaseProperty ]. Fill (0x69) is
NOT in the dat — pushed at runtime by gmVitalsUI::Update.
4. DrawModeType enum: Undefined=0, Normal=1, Overlay=2, Alphablend=3.
No "Stretch" value exists. Vitals uses Normal(1) and Alphablend(3) only.
5. Type values confirmed from RegisterElementClass: 3=Field/container,
7=Meter→UiMeter, 9=Resizebar, 0xC=Text, 2=Dragbar, 12=style prototype (skip).
6. Inheritance chain: vitals text labels (Type=0) inherit from base element
0x10000376 in layout 0x2100003F (Type=12), which carries font DID 0x40000000.
The full per-vital sprite id tables for 0x2100006C are confirmed.

Adds the 2026-06-13 dungeon-G.3 handoff doc + a dat-probe test that
RESOLVED the pivotal design ambiguity. A research agent assumed dungeon
landblocks are terrain-less (LandblockLoader.Load returns null ->
"rewrite the pipeline for terrain-less landblocks", 13 seams). The dat
probe refutes it: dungeon landblock 0x0125 has a flat (all-zero-height)
LandBlock record PLUS 71 EnvCells and no buildings/objects -> it streams
fine via the existing pipeline as a flat-terrain landblock.
The real blocker (#133) is narrow: the teleport-arrival handler
(GameWindow.cs:4928) snaps the player via physics.Resolve BEFORE the
dungeon landblock streams in -> Resolve falls back to the resident
Holtburg landblocks -> places the player at A9B3 ocean. Fix shape:
hold-until-hydration (reuse the #107 IsSpawnCellReady gate for the
teleport-arrival path) + place into the EnvCell + the retail
TeleportAnimState portal-space FSM for the full-G.3 loading screen.
ACE confirms dungeons are single-landblock, so "multi-landblock LOD"
is moot.
The handoff captures: this session's closes (#108-residual/#127/#125
gated, #116 partial), the M1.5 re-open decision, the corrected root
cause, the 5-way reference grounding (holtburger/ACE/retail decomp +
the dat probe), the design direction, and the open brainstorm questions.
Next session: resume the brainstorm at "propose approaches" -> spec ->
writing-plans -> implement.

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 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.

Deliverable 1: docs/research/2026-06-11-building-render-acdream-vs-retail-
comparison.md - the acdream-vs-retail architecture comparison synthesized
from two ultracode mapping fan-outs (11/12 areas, ~90 agents, every retail
claim Ghidra/pc-cited, every acdream claim file:line, 40/76 divergences
adversarially verified so far; raw per-area evidence committed under
docs/research/2026-06-11-holistic-map/).
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
(dat-confirmed); (3) retail never geometrically clips world geometry -
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
corrections (signed other_portal_id >= 0 gate).
Deliverable 2: docs/plans/2026-06-11-building-render-port-plan.md - the

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

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 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.

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).

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.

Separates what is measured (eye smooth + 1um at rest -> not jitter) from the leading-but-unproven hypothesis (clip edge-on) and the NOT-ruled-out alternative (camera position: retail eye collided/head-on 93%, ours floats edge-on). The one 'clean' pass had ratio 4.2x back-and-forth, so the flood claim is indicated not proven. Lists the verify-first steps before any R-A2b fix. Counters this session's pattern of overclaiming then refuting.

Attached cdb to the live 2013 retail client at the Holtburg doorway + read the decomp.
The indoor flap is a STRUCTURAL divergence, settled by measurement (not inference):
- Retail has ONE render path: DrawInside(viewer_cell) every frame. NO inside/outside
branch (RenderNormalMode's outside branch is dead code; is_player_outside only gates
sky/lighting). "Entering a building" is not a render event — only the camera sweep
resolving a different viewer_cell. Same path before/after threshold -> no seam.
- Retail's eye JITTERS ~36um at rest yet membership is stable -> robustness is
STRUCTURAL: many small per-building floods (~7/frame, ~2 cells each, via terrain BSP
-> DrawPortal -> ConstructView(CBldPortal)), not one giant knife-edge flood.
- Our 3 divergences: (D1) invented inside/outside branch (GameWindow.cs:7498,
clipRoot = viewerRoot ?? _outdoorNode :7396); (D2) synthetic _outdoorNode; (D3) one
unified flood.
DECISION (user-approved): Option A — rip out branch + outdoor node, root always at the
real viewer_cell, one DrawInside, per-building rendering. Phased, conformance-tested,
visual-gated.
REFUTED by measurement (do not retry): bounded-propagation/churn (maxPop=1, 0/63k
reciprocals empty); byte-stable eye (retail's jitters ~36um — rest-snap cd974b2 failed +
regressed, reverted 9b1857a).
Lands the canonical exhaustive handoff for a FRESH session
(docs/research/2026-06-08-full-retail-render-port-OPTION-A-handoff.md), the CLAUDE.md
READ-THIS-FIRST banner, and reusable cdb apparatus. No project code changed; working tree
at the known-good baseline.

The 2026-06-08 AM "physics rest micro-jitter" diagnosis is refuted with primary
evidence (door-recheck 216K standstill records: 0 position re-snaps; player
byte-stable during the flap). Two adversarial verification sub-agents confirmed:
- Retail roots the render at the camera viewer_cell (swept from the player via
SmartBox::update_viewer 0x453ce0; DrawInside(viewer_cell) 0x453aa0) and toggles
DrawInside / LScape::draw -- so acdream's eye-cell rooting + inside/outside
toggle are RETAIL-FAITHFUL. The locked-design "root at player cell" is wrong.
- The flap is render membership instability, eye-motion-driven: the visible-cell
set oscillates (8<->3) as the eye sweeps monotonically. Root = the
re-enqueue-on-growth DRIFT (PortalVisibilityBuilder.cs:322, MaxReprocessPerCell
=16) re-clipping each grown cell every round -> sub-cm eye jitter flips membership.
Fix (spec, not yet implemented): verbatim port of retail's enqueue-once flood
(ConstructView + AddViewToPortals): enqueue once on first discovery, clip each
cell's portals once, union late growth in place (AddToCell) + draw-reorder
(FixCellList), never re-enqueue. Kills the drift; rooting/camera/seal untouched.

Apparatus + handoff for the indoor flap. Confirmed (primary evidence): the flap is the
portal-flood clip being µm-sensitive at the threshold, driven by a ~1-8µm jitter in the
player RenderPosition (physics resting position not bit-stable; Lerp surfaces it). REFUTES
the 2026-06-07 see-through/EnvCell/outdoor-node diagnosis (ModelId GfxObj 0x01000A2B IS the
solid exterior) AND an enqueue-once attempt (retail propagates late slices via AddToCell;
the existing PropagatesNewSlicesToExit test caught it; reverted). Adds: Build determinism
test, A8CellAudit gfxobj dump, [pv-input] 6dp probe + [render-sig] outRoot/bshell fields.
No functional fix shipped. Next: higher-precision physics rest trace -> port retail

The flip killed the branch-toggle flap (one path, zero OutdoorRoot frames). It exposed two residuals now PROVEN via a live [bshell] probe, not guessed: (1) oscillation = the outdoor-node flood membership swings 1<->~13 building cells frame-to-frame, so the walls (EnvCell shells) blink; (2) see-through = EnvCell wall polys are single-sided for SidesType==CounterClockwise, so from outside you see their culled back. The ModelId building shells DO render (6/6 with mesh) but are a partial frame, not the walls — the skip-all-interiors experiment proved the walls are the EnvCell shells. Fixes identified (stabilise flood + build back faces) but not implemented; full do-not-retry list + open pre-flip-reconciliation question in the doc.

Super-detailed pickup for the one remaining step that fixes the flap: the cutover
flip (terrain via OutsideView for the outdoor root + clipRoot=viewerRoot??_outdoorNode
+ launch + visual gate + delete old paths). Exact steps, current line numbers, the
de-risking already done (shell no-op, flood validated, OutsideView mechanism), the
4 render cases, the Step-B integration checklist, do/don't, and a kickoff prompt.

Checkpoint of the unified retail-faithful indoor render. The two-week HANG/grey is fixed and the
interior seals (live-verified by the user). Commits the session render-rewrite foundation together
with the fixes that made it functional.
- HANG fix: PortalVisibilityBuilder.Build portal flood did not terminate (the faithful ProjectToClip
near-side clip drifts per round, defeating the CellView dedup; the BFS had no bound after U.2a removed
MaxReprocessPerCell). Fix = drift-tolerant snapped/canonical CellView.Add dedup (PortalView.cs) plus
restored MaxReprocessPerCell=16 bounded re-enqueue (PortalVisibilityBuilder.cs). Re-enqueue is kept
(load-bearing for late-slice propagation, Build_ViewGrowthAfterDoneCell_PropagatesNewSlicesToExit);
only its count is capped. CellViewDedupTests added.
- Seal (DrawCells Task 2): RetailPViewRenderer.DrawEnvCellShells draws EVERY visible cell via
IndoorDrawPlan.ShellPass (was gated on the ClipFrameAssembler slot filter, leaving slot-less cells grey).
- Look-in FPS: GameWindow exterior look-in candidates limited to the player landblock +-1 (was all ~81
loaded LBs iterated every outdoor frame). No behaviour change (far cells were >48m, already culled).
Remaining dominant issue = the FLAP at transitions: viewer-cell metastability (render roots at the
camera-eye cell, which oscillates outdoor-indoor as the 3rd-person boom drifts across the doorway,
confirmed in render-sig). SEPARATE fix, NOT the DrawCells port. Full handoff + flap fix plan + tracked
follow-ups (#78 terrain, look-in-from-inside, look-in FPS, L-spotlight):
docs/research/2026-06-07-indoor-render-session-handoff.md.
Baselines: build 0 err; App.Tests 210/210; Core.Tests 1331 pass / 4 fail (pre-existing) / 1 skip.

Task-by-task plan (TDD pin for the grey regression + per-task visual gates) to replace the
indoor-render approximation with a verbatim PView::DrawCells port, sequenced so Task 2 alone
should kill the grey. Pickup handoff for a fresh session: state, baselines, rules, do-not-relitigate.
Local commit only (not pushed).
