cf62793304 fix(render): A7 Fix D D-1 — clamp the point-light sum on its own (#140)
accumulateLights folded ambient+sun+torches into one accumulator clamped only
in the frag, so a few warm intensity-100 torches blew walls/objects to white.
Mirror retail SetStaticLightingVertexColors: sum point/spot into pointAcc, clamp
to [0,1] (the baked emissive), THEN add ambient+sun, frag final-clamps. Matches
LightBake.ComputeVertexColor (LightBakeConformanceTests). Per-light cap unchanged.

57c11358b6 fix(sky): A7 — correct sun-vector magnitude (ambient + sun were ~32% too bright)
Outdoor lighting was ~32% too bright (washed-out, weak shading). Live cdb on
retail (SmartBox::SetWorldAmbientLight + SkyDesc::GetLighting + LScape::sunlight,
binary matches refs/acclient.pdb) pinned it: at the SAME game time + DayGroup,
acdream's ambient COLOR matched retail exactly (the purple is correct, authored
per-time-of-day in the sky dat) but the LEVEL was 0.607 vs retail's 0.459.

level = AmbBright + 0.2·|sunVec|, both AmbBright=0.40, so acdream's |sunVec|≈1.06
vs retail's ≈0.30. Retail's LScape::sunlight read live = (0.2238, ~0, 0.00352),
magnitude 0.224 = DirBright, y≈0.

RetailSunVector had `y = cos(P)` (≈1) — the raw PRE-transform value SkyDesc::
GetLighting writes to arg5 (0x00500ac9), before LScape::set_sky_position's
world transform. acdream ported the un-transformed vector, so the y=cos(P)≈1
term inflated |sunVec| to ~1.06. That magnitude feeds BOTH the ambient boost
(SkyKeyframe.AmbientColor) AND the sun colour (SkyKeyframe.SunColor =
DirColor×|sunVec|), over-brightening the whole scene (terrain, objects, sky)
~30% and also pointing the sun the wrong way.

Fix: RetailSunVector = DirBright × (cos(P)·sin(H), cos(P)·cos(H), sin(P)) — the
world-space spherical form LScape::sunlight actually holds; |sunVec| == DirBright
for all H/P. After: acdream ambient (0.353,0.176,0.449) vs retail (0.360,0.180,
0.459) — within ~2%, user-confirmed "better outside". Sun direction also corrected
(was pointing ~North from the bad y term).

Tests updated to the cdb-verified values (the prior tests pinned the inflated
magnitude). 18/18 sky tests green. reference-retail-ambient-values memory updated.

4345e77d62 fix(render): A7 Fix B — per-OBJECT point-light selection (minimize_object_lighting)
Outdoor objects brightened as the camera approached: lighting selected the
nearest 8 lights to the VIEWER and fed that one global set to everything
(LightManager.Tick), so a building's wall torches only lit it once the camera
got close enough for them to win the global top-8. Probe confirmed the scale of
the problem: a single Holtburg view registers 129 point lights — the global cap
of 8 was hopeless.

Retail selects up to 8 lights PER OBJECT by the object's own position
(minimize_object_lighting 0x0054d480), so a torch always lights the wall it
sits on, camera-independent. Ported faithfully:

- LightManager.SelectForObject (pure, TDD, 8 new tests): candidacy
  (light.pos − center)² < (Range + radius)², nearest-8 among those. Plus
  BuildPointLightSnapshot for the per-frame stable-indexed light list.
- mesh_modern.vert: two SSBOs — binding=4 GLOBAL point-light array (the
  snapshot), binding=5 per-instance light SET (8 int indices into it, -1 =
  unused), parallel to the binding=0 instance buffer (mirrors the U.3 clip-slot
  mechanism). accumulateLights keeps ambient + sun from the SceneLighting UBO
  (cleared as faithful by the lighting audit) and loops THIS instance's point
  lights. pointContribution factored out (same calc_point_light wrap+norm shape).
- WbDrawDispatcher: per-entity light set computed ONCE at the isNewEntity site
  (constant across the entity's parts), by the entity's AABB sphere; threaded
  into grp.LightSets parallel to grp.Matrices; global + per-instance buffers
  uploaded in Phase 5. Camera-independent ⇒ stable for static buildings.
- GameWindow: BuildPointLightSnapshot + dispatcher.SetSceneLights each frame.

Tests: 17/17 LightManager + 36/36 dispatcher clip-slot/clip-frame green
(parallel-array lockstep preserved). Visually gated: the meeting hall now holds
steady as the camera approaches (was the popping symptom).

aa94cedc38 fix(render): A7 point-light shape — per-vertex Gouraud + faithful calc_point_light (wrap + norm)
The torch/point-light look was wrong two ways, both now fixed against the
named retail decomp (calc_point_light 0x0059c8b0) via our verified
LightBake.PointContribution port:

1. Per-PIXEL → per-VERTEX. accumulateLights moved from mesh_modern.frag to
   mesh_modern.vert so point lights Gouraud-interpolate across each triangle
   the way retail's fixed-function T&L does. The per-pixel eval made a tight,
   hard-edged "spotlight" pool on flat walls; per-vertex is a soft, broad
   gradient. frag now just consumes the interpolated vLit (+ fog + flash).

2. Simplified ramp → faithful calc_point_light shape. The live point/spot
   branch was max(0,N·L) × linear(1−d/range) × cap — missing two terms our
   LightBake.cs port already has:
     • half-Lambert WRAP (1/1.5)·(N·D + 0.5·d), D un-normalised — a face
       angled away from a torch still catches light (retail's soft terminator)
       instead of snapping to black.
     • distance-cube NORM branch norm = distsq>1 ? distsq·d : d — inverse-
       square-ish soft far halo + punchy near field, vs the flat linear ramp.
   Per-channel no-blowout cap (min(scale·color, color)) retained.

The per-channel cap was also added to the legacy mesh.frag for consistency.

A read-only retail-vs-acdream lighting audit (11-agent workflow) confirmed
these two as the cause of the "better but a bit off" look and cleared the
ambient/sun/terrain/color-space chain as already faithful. Remaining
confirmed divergences (per-object light selection; dungeon static vertex
bake) are filed as the next fixes.

6f81e2c91d fix(render): hide editor-only placement markers in dungeons — port retail's degrade-to-nothing (#136)
The "red cone" (+ green floor petals) in the 0x0007 Town Network dungeon is a dat
EnvCell static object (Setup 0x02000C39 / GfxObj 0x010028CA) using pure red/green
MARKER textures (0x08000109 / 0x0800010A). It is an EDITOR-ONLY placement marker:
its DIDDegrade table 0x11000118 is {slot0 Id=mesh MaxDist=0, slot1 Id=0 MaxDist=FLT_MAX},
i.e. visible ONLY at distance 0 (the WorldBuilder editor origin) and degraded to
GfxObj id 0 (nothing) at any real distance. retail's distance-based degrade
(CPhysicsPart::UpdateViewerDistance 0x0050E030 -> Draw 0x0050D7A0) therefore never
draws it in the live client.

acdream's render pipeline is extracted from WorldBuilder, which (being an editor)
renders every cell static's base mesh directly and has NO degrade handling at all
(zero DIDDegrade references in references/WorldBuilder) — so acdream inherited the
"show the marker" behavior and drew it forever. It only became visible now because
the #135 login-into-dungeon fix drops the player at the exact saved spawn next to it.

Fix: GfxObjDegradeResolver.IsRuntimeHiddenMarker() detects the editor-marker pattern
(HasDIDDegrade + Degrades[0].MaxDist==0 + a degrade entry with Id==0). The EnvCell
static-object hydration (GameWindow ~5793) skips such GfxObjs — whole-stab for bare
GfxObj stabs, per-part for Setup stabs (an all-marker Setup then drops via
meshRefs.Count==0). This is the faithful equivalent of retail's runtime degrade for
static geometry (always viewed at distance > 0); real LOD objects (slot0.MaxDist>0)
and degrade-to-real-mesh objects are untouched.

Diagnosis was extensive (geometry-not-VFX via particle-off; texture-not-lighting via
flat-ambient frame dumps; per-surface runtime decode pinned the red/green marker
surfaces; a draw-time probe pinned the dat-static entity id; a dat dump of the Setup +
degrade table confirmed the editor-marker pattern). Verified live via a frame dump:
the red cone + green petals are gone, all real dungeon decorations still render.
4 new GfxObjDegradeResolver unit tests cover the marker / normal-LOD / no-table /
degrades-to-real-mesh cases.

2c923755c4 fix(G.3): place the player on the cell floor for an indoor dungeon login (#135 follow-up)
Two regressions from the pre-collapse (712f17f), found by live gate + a runtime
probe:

1) Login-into-dungeon stopped loading the dungeon. The login-hold streaming
   observer fell through to the OFFLINE fly-camera branch once
   _lastLivePlayerLandblockId was filtered to the player guid (a dungeon-local
   NPC used to keep it pinned). A camera-derived observer far from the
   pre-collapsed dungeon tripped ExitDungeonExpand and unloaded it. Fix: a LIVE
   in-world session never uses the fly camera for the observer — it follows the
   player's server landblock, falling back to the recentered spawn center
   (_liveCenterX/Y). The fly camera is the OFFLINE observer only.

2) Even with the dungeon resident, auto-entry hung: the #106 "ground ready" gate
   required SampleTerrainZ under the spawn, but a dungeon's negative-offset cells
   place the spawn's WORLD position in a NEIGHBOUR terrain landblock the #135
   collapse deliberately doesn't load (probe: cellReady=True, terrReady=False
   forever). The terrain gate is wrong for an indoor spawn — the player lands on
   the EnvCell FLOOR. Fix: gate an indoor (hydratable) spawn/teleport on
   IsSpawnCellReady, not the terrain heightmap; outdoor (and unhydratable→demote)
   spawns still hold on terrain. Applied to both isSpawnGroundReady (login auto-
   entry) and TeleportArrivalReadiness (teleport). This is the faithful equivalent
   of retail's synchronous cell load + place-on-floor; the pre-#135 terrain hold
   only passed because the 25x25 window streamed the neighbour terrain.

Verified live: login into 0x0007 → auto-entered player mode, snapped to
0x00070145, dungeon renders, FPS steady. Register AD-2 amended.

712f17f0f2 fix(G.3): pre-collapse dungeon streaming at login/teleport — kill the login FPS ramp (#135)
On login (or teleport) into a dungeon, FPS started ~10 and climbed over ~30 s.
Root cause: the dungeon "collapse" (which shrinks the 25x25 streaming window to
the player's single dungeon landblock — AC dungeons have no neighbours) only
fires once the per-frame `insideDungeon` gate reads true, and that gate keys on
the physics CurrCell, which isn't set until the player is PLACED, which waits for
the dungeon landblock to hydrate. So during the whole hydration window NormalTick
bootstraps the full window — ~24 unrelated ocean-grid neighbour dungeons + their
~19k entities each — and the collapse only mops them up afterward. That mop-up is
the ramp.

Fix: trigger the SAME collapse early, the instant we recenter the streaming center
onto a sealed dungeon cell, before the first NormalTick.

- StreamingController.PreCollapseToDungeon(cx,cy): fires EnterDungeonCollapse
  early (idempotent). The expensive neighbour window is never enqueued.
- GameWindow.IsSealedDungeonCell(cellId): reads the EnvCell dat SeenOutside flag
  (CurrCell is null pre-placement) — the same flag ObjCell.SeenOutside and the
  per-frame gate use, so the early decision matches the eventual one. Distinguishes
  a real dungeon from a cottage/inn interior (SeenOutside → keeps its outdoor
  surround). Excludes the 0xFFFE/0xFFFF structural shell ids so an outdoor spawn id
  can't type-confuse a LandBlock record as an EnvCell.
- Hooks: OnLiveEntitySpawnedLocked (login) + OnLivePositionUpdated (teleport).
- Observer robustness: during a teleport PortalSpace hold the streaming observer
  follows the recentered destination, not the frozen pre-teleport position (which
  could drift >=2 landblocks off and trip ExitDungeonExpand). And
  _lastLivePlayerLandblockId is now filtered to the player guid (resolves the
  Phase A.1 TODO) so a stray NPC UpdatePosition can't drift the login-hold observer
  off the dungeon.

Faithful EARLY trigger of the existing AP-36 collapse mechanism, not a new
workaround — AP-36 amended in the same commit. Adversarially reviewed across
timing / threading / faithfulness lenses; 5 new tests including the real runtime
ordering (Tick bootstraps, then PreCollapse cancels). Core suite green (1463).

3b93f91ebe feat(A7): LightBake Core — verified per-vertex static-light burn-in (foundation, not wired)
The faithful fix for the spotty dungeon/house/outdoor lighting is retail's per-vertex
static-light bake (D3DPolyRender::SetStaticLightingVertexColors 0x0059cfe0), NOT a
per-pixel ramp. This lands the GL-free Core: LightBake.PointContribution /
ComputeVertexColor port calc_point_light (0x0059c8b0) VERBATIM — verified against a
clean Ghidra decompile (the BN pseudo-C is x87-mangled): half-Lambert wrap with
LIGHT_POINT_RANGE=0.75 (0x007e5430), the distsq>1 norm branch, the per-channel
min-to-color clamp, and the final [0,1] clamp. static_light_factor=1.3 (0x00820e24)
is already folded into LightSource.Range by LightInfoLoader.

7 conformance tests (hand-derived golden values) green. NOT wired yet — the
integration (a per-vertex colour attribute on the cell mesh + the bake driver keyed
on envCellId + the shader consumption) is the remaining A7 work; see ISSUES.md A7.

3e641339e9 chore(G.3): strip the #133 temp diagnostics
Remove the throwaway probes added to diagnose the dungeon FPS/grey issues now that
they're fixed: the ACDREAM_LOG_FPS headless line + [cellreg] registration line
(GameWindow), and the [pv-trace] 0x0007 gate-widen + raw-NDC bbox addition to the
flap probe (PortalVisibilityBuilder, reverted to the pre-#133 form). The permanent
Phase-U.4c [flap]/[pv-trace] probes (ACDREAM_PROBE_FLAP) are kept as-is.

3e006d372a fix(G.3): register connector cells in the PHYSICS graph too — viewer-cell transit (#133)
After registering portals-only connector cells for VISIBILITY (d90c538), an
angle-dependent residual grey remained when the camera crossed a ramp: the
camera-collision sweep (SmartBox::update_viewer -> sphere_path.curr_cell, pc:92870)
could not transit INTO the connector cell because it had no physics cell to sweep
into — CacheCellStruct was still gated on drawable sub-meshes. So the viewer cell
stalled one cell behind the eye (confirmed live: [flap-sweep] transited every cached
neighbour but NEVER the un-cached connector 0x014D, viewerCell stuck at 0x00070103
while the eye sat 1.32 m past the connector's portal plane), and the side test
correctly culled the on-screen connector portal -> grey.

Fix: move CacheCellStruct out of the `cellSubMeshes.Count > 0` gate, next to
BuildLoadedCell — cache EVERY cell with a valid cellStruct for physics too. Retail
keeps the whole landblock cell array resident for the sweep; a portals-only
connector has an empty collision BSP but its portals drive the transit. User-gated:
"I see no grey background any longer."

Build green; 12 flood-gate tests + 677 physics/cell/transit tests green (no collision
or membership regression). TEMP render probes still retained (strip after).

d90c5385d2 fix(G.3): register portals-only connector cells for visibility (#133 ramp grey)
The grey "barrier" at a dungeon ramp was a one-cell registration gap. The ramp's
connector cell (0x0007014D) is a portals-only pass-through — CellMesh.Build yields
0 drawable sub-meshes for it (you walk through it on adjacent floors). But the whole
registration block — including the portal-VISIBILITY registration (BuildLoadedCell ->
_cellVisibility) — was gated behind `if (cellSubMeshes.Count > 0)`. So that cell was
never added to the visibility graph; the flood lookup-missed it (PortalVisibilityBuilder
:369), couldn't traverse it to the room below, and the grey clear color showed through.

Confirmed live via two added probes: [cellreg] registered=204/205 (only 0x014D missing)
+ [pv-trace] p4->0x0007014D skip=lookup-miss. After the fix: registered=205,
hasRamp=True, skip=lookup-miss gone, the room below renders.

Fix: compute the cell transforms and call BuildLoadedCell (visibility) for EVERY cell
with a valid cellStruct, regardless of drawable sub-meshes — matching retail, which
keeps the whole landblock cell array resident before the flood runs. Drawing
(RegisterCell, _pendingCellMeshes) and the physics BSP (CacheCellStruct) stay gated on
drawable geometry (a portals-only connector has nothing to draw and no collision
surface). Not a regression from the FPS-collapse work — a pre-existing gate the
now-navigable dungeon exposed (every ramp/stair/cellar mouth would show it).

TEMP diagnostics retained for the residual angle-grey investigation (strip after):
[cellreg] (GameWindow), the 0x0007 [pv-trace] gate widen + raw-NDC bbox (PortalVisibility-
Builder). Three earlier render-math theories (portal_side, on-screen clip, near-eye
projection) were each refuted by apparatus/probe before shipping — this is the verified one.

7d8da99f79 fix(G.3): collapse dungeon streaming at the snap, not after landblock finalize (#133)
The dungeon-streaming gate read SeenOutside from the render registry
(_cellVisibility.TryGetCell), which only succeeds AFTER the landblock FINALIZES —
~tens of seconds for a 205-cell dungeon. So the collapse fired late and the full
25x25 neighbor window churned in first ("~30s to stabilize at high FPS").

EnvCell extends ObjCell, which already carries SeenOutside (set from the EnvCell
dat flags at construction), so CurrCell.SeenOutside is available the moment the
player is placed (the snap). Read it directly instead of the registry. Collapse now
engages ~3s in (snap) instead of ~30s (finalize); residual is the ~24 neighbors the
bootstrap loads before the snap, which then unload. Also simplifies the predicate.

53e22a350d fix(G.3): relocate the player entity to its CELL landblock indoors, not position-derived (#133)
After the dungeon-collapse fix the local player avatar stopped rendering: the
per-frame RelocateEntity moved the player entity to its position-derived landblock
floor(pp/192), which for a dungeon's negative-local-Y cell is the off-by-one (0,6)
— the very landblock the collapse unloads. So the player entity sat in an unloaded
landblock and was never drawn (the dungeon itself, in 0x0007, rendered fine).

Fix: when the player is in an indoor cell (CellId low word >= 0x0100), relocate to
the cell's OWN landblock (CellId >> 16), matching the streaming-collapse pin. The
cell id is authoritative for ocean-placed dungeon geometry. Outdoor entities keep
the position-derived path.

2561918a70 fix(G.3): pin dungeon collapse to the cell's landblock, not the position-derived one (#133)
"The dungeon is broken" — the collapse was unloading the REAL dungeon. A dungeon's
EnvCells sit at arbitrary "ocean" world coords with negative cell-local Y (snap
showed pos=(58.9,-69.6) in cell 0x00070133), so the observer landblock
_liveCenterY + floor(pp.Y/192) = 7 + floor(-69.6/192) = 7 + (-1) = 6 lands one row
off. The collapse pinned to 0x0006 and unloaded 0x0007 — the real dungeon — which
nulled CurrCell (the cell no longer existed) and left the player floating in
outdoor-lit empty space (lb 1/1 @ ~1585 fps, but the wrong landblock). This is the
Bug-A negative-local-coordinate class.

Fix: when inside a dungeon, pin the collapse to the cell's OWN landblock
(CurrCell.Id >> 16), never the position-derived observer landblock — the cell id is
the authoritative landblock for ocean-placed dungeon geometry.

Also hardened the hysteresis so a transient CurrCell flicker can't thrash:
- Re-collapse when insideDungeon at a DIFFERENT landblock (multi-landblock dungeon).
- Expand only on a DISTANT move (Chebyshev > 1) — a real exit teleports far from the
  ocean-grid block; the off-by-one flicker is always an ADJACENT (±1) landblock, so
  it now HOLDS the collapse instead of expanding.
- SweepCollapsed always preserves _collapsedCenter (the true dungeon landblock),
  never the per-frame observer landblock.

Build green; 59 streaming tests green (flicker regression test updated to the
realistic adjacent off-by-one).

d9e7dd65e9 fix(G.3): hysteresis on the dungeon streaming gate — stop collapse↔expand thrash (#133)
The first cut of the dungeon gate keyed expand on the per-frame insideDungeon
signal (CurrCell is a sealed EnvCell). Live, CurrCell momentarily resolves to
null mid-frame while the player stays put in the dungeon landblock, so the gate
flipped collapse→expand→collapse every few frames. Each expand re-streamed the
full 25×25 window; the unloads couldn't keep up (MaxCompletionsPerFrame=4), so
registered lights leaked to 212k and FPS spiked to single digits between the
~199 fps collapsed frames.

Fix: once collapsed, key the gate on the STABLE observer landblock, not CurrCell.
Stay collapsed while the player remains in the dungeon landblock (_collapsedCenter);
expand only when the observer actually moves to a different landblock (portal/
teleport out). CurrCell flicker no longer thrashes.

Regression test added (Collapsed_CurrCellFlickersToNull_SameLandblock_DoesNotExpand).
Build green; 60 streaming tests green.

56860501b6 fix(G.3): collapse streaming to the single dungeon landblock indoors (#133 FPS)
Dungeon FPS sat at ~30 (frame ~33ms) because the 25x25 streaming window around
the dungeon landblock pulled in ~129 NEIGHBORING landblocks + their thousands of
torch/particle emitters, all drawn though never visible. In AC all dungeons are
packed adjacent in the unused "ocean" map grid, so those neighbors are unrelated
dungeons. The FPS timeline proved it: 247 fps at login (lb 0/0, ~10K entities) →
17 → 30 as landblocks streamed in (lb 0→129) — the cost tracked LANDBLOCK count,
not entities.

Retail-faithful: ACE LandblockManager.GetAdjacentIDs returns ZERO adjacents for a
dungeon (`if (landblock.IsDungeon) return adjacents;`, Landblock.cs:577-582) —
every dungeon is a self-contained landblock you never see out of.

Fix: when the player stands in a sealed indoor cell (CurrCell.IsEnv &&
!SeenOutside — the same predicate that kills the sun/sky), collapse streaming to
just the player's dungeon landblock and unload the neighbors. Building interiors
(cottage/inn) have SeenOutside cells, so they are NOT gated and keep their
surrounding terrain (the frozen building/cellar demo is unaffected). Unloading the
neighbors also tears down their lights (removeTerrain → UnregisterOwner), shrinking
LightManager._all from ~2227 toward retail's ≤40 — which directly helps the A7
lighting bake landing next.

Mechanics (StreamingController):
- Edge IN: ClearPendingLoads() cancels the in-flight 25x25 window (new streamer
  ClearLoads control job — worker drops queued Loads, keeps Unloads), unload every
  resident neighbor, pin a radius-0 StreamingRegion, (re)load the dungeon block if
  needed.
- Stay collapsed: sweep any straggler that finished loading after the edge (a Load
  the worker had already dequeued before ClearLoads).
- Edge OUT (portal/teleport to outdoors): rebuild the full two-tier window at the
  new center, unload anything stale.

AP-36 added to the divergence register (the gate uses the cheap SeenOutside cell
predicate as an approximation of ACE's full landblock IsDungeon classification).
GameWindow also carries a TEMP ACDREAM_LOG_FPS=1 headless FPS line (strip after
the A7 FPS+lighting verification).

Build green; 58 streaming tests green (6 new dungeon-gate tests).

007e287309 fix(A7): port retail calc_point_light (1-dist/falloff) ramp — kill the "spotlight" hard edge (#133)
The dungeon/house/outdoor lights read as hard-edged blown discs ("spotlights")
because our point/spot shader used `atten = 1.0` flat inside a hard `d < range`
cutoff. The mesh.frag comment claimed this was retail-faithful ("no attenuation
inside Range... the bubble-of-light look relies on crisp boundaries", citing
r13 10.2) — that was a misread and the literal cause of the symptom.

Verified against the decomp (not guessed): calc_point_light (0x0059c8b0, the
PER-VERTEX point-light path that lights static walls) scales each light's
contribution by (1 - dist/falloff_eff) — a LINEAR ramp that fades to exactly 0
at the edge, eliminating the hard disc. falloff_eff = Falloff * static_light_factor,
and static_light_factor = 1.3 (0x00820e24), NOT the 1.5 config_hardware_light
rangeAdjust (that 1.5 is the D3D-dynamic path for moving objects, a different
path). The Ghidra port (acclient.c:808639) is more garbled — BN pseudo-C is the
oracle here; the exact normalization factor + a half-Lambert wrap (0.5*dist+N*L)
are x87-obscured (same artifact class as GetPowerBarLevel) and left unported.

Changes:
- mesh_modern.frag + mesh.frag: replace flat atten with clamp(1 - d/range, 0, 1);
  Range now carries falloff_eff so the ramp fades to 0 at the cutoff. Fix the
  false "no attenuation / crisp bubble" comment in mesh.frag.
- LightInfoLoader: Range = Falloff * 1.3 (static_light_factor), was * 1.5.
- LightManager: correct the stale class doc comment (Tick is now nearest-8
  allocation-free partial-select with NO viewer-range slack filter).
- divergence register: AP-16 updated (slack filter removed), AP-35 added
  (per-pixel vs per-vertex Gouraud; dropped half-Lambert wrap + normalization).
- test: LightingHookSinkTests Range 8*1.3 = 10.4.

Build + 20 lighting tests green. Visual gate pending (game-wide lighting change:
dungeon torches, house candles, outdoor braziers).

5872bcf075 perf(lighting): allocation-free nearest-N light selection (#133 FPS)
Tick built a new List<>(N) and ran an O(N log N) Sort every frame; in a dungeon
N is thousands of torches, so it allocated a large list per frame (GC pressure ->
FPS). Replace with an insertion partial-select that keeps the nearest maxPoint
directly in the _active window — O(N * maxPoint), maxPoint<=8, zero allocation.
Same selection result (nearest 8); lighting suite 20/20 green.

1e70a5a484 fix(G.3 A7): torch range = Falloff x 1.5 (retail rangeAdjust) — wider pools (#133)
Retail PrimD3DRender::config_hardware_light (0x0059ad30) sets the hardware light
Range = Falloff * rangeAdjust (1.5, global 0x00820cc4). We used Range = Falloff, so
torches reached only 2/3 of retail -> tight 'candle/spotlight' bubbles in dungeons.
Match retail's reach. Ambient 0.20 confirmed retail-faithful (the 0.30 was CreatureMode,
not world cells). Lighting suite green.

a80061b0c2 fix(G.3 A7): dungeon lighting — select 8 NEAREST lights, not viewer-in-range (#133)
The active-light selection dropped any point light whose range didn't reach the
VIEWER (DistSq > Range^2*slack -> skip). Retail's D3D-style fixed pipeline picks
the 8 NEAREST lights and applies the hard range cutoff PER SURFACE in the shader
(mesh_modern.frag: if (d < range)). The viewer-range candidacy filter suppressed
a torch whenever the player stood outside its range, so a dungeon room with 2227
registered torches lit only the ~1 the player was standing in (activeLights ~= 1,
rest of the room at flat 0.2 ambient = the "lighting off" report). Drop the filter;
take the nearest 8 regardless of viewer range. Removed the now-unused RangeSlack
const; updated the two tests that codified the old filter. Core lighting suite green.

A character saved inside a far dungeon hung at the #107 auto-entry hold because
the streaming center was fixed at the startup default and the login spawn never
recentered it, so the dungeon never streamed. Mirror the teleport-arrival
recenter on the login player-spawn path: when the player's spawn landblock
differs from the current center, recenter before translating the spawn position

The "consumed by nobody (zero behavior change)" / "INERT in Stage 1 (no writer)"

CellGraph is populated unconditionally in CacheCellStruct (before the idempotency

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).

2ce5e5c862 fix(G.3a): validated-claim placement keeps the claim's landblock prefix (#133)
The #111 validated-claim branch returned lbPrefix | (cellId & 0xFFFF), where
lbPrefix is found by searching resident landblocks for one containing the
candidate position. A dungeon EnvCell's local Y can be negative, so the dungeon
landblock fails the [0,192) bounds test and the loop matches a neighbouring
(e.g. Holtburg) resident block -> the validated claim 0x00070143 got re-stamped
0xA9B30143, making the client mis-resolve the player to the wrong landblock and
spam ACE with rejected moves. The validated claim's full id is authoritative;
return it directly. Byte-identical for the login case (position in the claim's
own landblock); fixes the far-teleport dungeon case.

3238f1fde4 docs(G.3a): note CacheCellStruct's unconditional UCG CellGraph add is inert (#133)
Code-review follow-up: the hydration decouple's safety rests not only on
CacheCellStruct self-gating its BSP cache, but on the fact that a geometry-less
cell — though now added to the UCG CellGraph unconditionally — never enters the
_cellStruct BSP dictionary membership/placement resolve through, so the player
can never be rooted in one. Document that load-bearing invariant at the hoist.

BuildLoadedCell + CacheCellStruct were gated behind cellSubMeshes.Count > 0, so a
geometry-less collision cell got no collision (fall-through) and no visibility
node. Retail couples neither to visible geometry; CacheCellStruct self-gates on a

8682a8db70 close #125: bounded upload retry kills the sticky-drop debt (failed GL uploads were never re-staged)
The GL root cause was fixed in fcade06 (the gpu_us query-ring stale
errors). This closes the remaining design debt: a genuinely-failed
UploadMeshData was dropped permanently.

Exact mechanism (traced this session): UploadMeshData's catch returns
null, the staged item is already consumed, and _renderData stays empty -
but the prepared data lingers in _cpuMeshCache, so the #128 EnsureLoaded
re-arm hits PrepareMeshDataAsync's CPU-cache short-circuit
(ObjectMeshManager.cs:448-453) which returns the cached data WITHOUT
re-staging it for upload. The mesh stays invisible until CPU-cache
eviction - session-sticky under low cache pressure (the in-tower
scenario).

Fix: the per-frame Tick drain (WbMeshAdapter) now re-stages a failed
upload for the NEXT frame via ObjectMeshManager.UploadOrRequeue, bounded
by MaxUploadRetries (3). The attempt counter lives on the ObjectMeshData
object so it resets to 0 naturally on re-prepare. Re-stages are
collected and re-enqueued AFTER the drain loop, never inside it, so a
deterministic failure cannot spin the queue within a single frame; past
the cap it gives up with a loud [up-retry] ... giving up line - a
genuine GL defect now surfaces instead of the old silent permanent drop
or an unbounded retry storm. Retail loads content synchronously and has
no such failure mode; this converges the async pipeline toward that
guarantee.

The uncaught GenerateMipmaps path (open-question c) is INTENTIONALLY
left to surface errors - a blanket catch there would mask future real
defects (no-workarounds rule), and its trigger (fcade06) is retired.

No visual gate (robustness). Build green; App.Tests 264 + WbMeshAdapter
tests green. No GL-context test seam exists for the upload path, so the
bounded retry is verified by construction + the regression suite.

bf18a54369 fix #116 (partial, Ghidra-confirmed): slide_sphere degenerate guard uses F_EPSILON, not EpsilonSq
The user brought up Ghidra; its decompiler (patchmem.gpr, full PDB)
resolved the Binary-Ninja `test ah,5` x87 branch-sign ambiguity that
blocked the desk read. CSphere::slide_sphere (0x00537440) decompiles
cleanly to:

  fVar3 = |cross(collisionNormal, contactPlane.N)|²;
  if (::F_EPSILON <= fVar3) {                       // crease exists
      ... offset = cross * dot(cross,gDelta)/fVar3;
      if (|offset|² < ::F_EPSILON) return COLLIDED_TS;   // degenerate guard
      ... add_offset_to_check_pos -> SLID_TS
  }

Retail compares the SQUARED magnitudes against F_EPSILON
(0.000199999995 ~= 0.0002 = PhysicsGlobals.EPSILON). Our port compared
against EpsilonSq (0.0002^2 = 4e-8) - a ~5000x too-tight threshold (the
BN pseudo-C rendered the comparison as `test ah,5` after an x87 FCMP,
which is sign-ambiguous; agent reads disagreed). Fixed both comparisons
at TransitionTypes.cs:3098,3105 to EPSILON.

Effect: crease-exists now needs >=0.81 deg between the wall and contact
normals (was 0.011 deg - which routed near-parallel pairs through the
numerically unstable projection); the degenerate guard now hard-stops
slides under ~1.41 cm like retail (was 0.2 mm). Branch POLARITY was
already correct - no change there.

No regression: full physics suite (612) + full Core (1443) green. Not a
register deviation (no row existed; this is an undocumented porting
error corrected to match retail).

This does NOT close #116 - it fixes a tangential constant, not either
reported shape. Ghidra also settled the two shapes' diagnosis (recorded
in ISSUES.md #116 + physics digest):
- Shape-1: our cn=UnitZ default IS retail-faithful (validate_transition
  0x0050aa70 has the identical `if (collision_normal_valid==0)
  set_collision_normal(UnitZ)`). The real divergence is upstream -
  tick-22760 our collision_normal_valid was false where retail's was
  true (it recorded the door-face normal). Needs the instrumented
  tick-22760 replay.
- Shape-2 (D4 stays skipped, note sharpened): slide_sphere slides
  in-frame (SLID_TS) so Z=1.92 is faithful and the D4 Z=2.0 hard-stop
  pin is the suspect half; the threshold fix didn't move D4 (real slide,
  not degenerate). Needs a cdb trace of an airborne wall hit.

96a425a9a5 fix #108-residual (root cause): terrain drew DOUBLE-SIDED - port retail landPolysDraw eye-side gate as terrain backface cull
The cellar-ascent grass window was the UNDERSIDE of the z~94 grade
sheet. Retail terrain is single-sided: ACRender::landPolysDraw
(0x006b7040) draws each land triangle ONLY when the camera is on the
POSITIVE (upper) side of its plane (Plane::which_side2 vs
Render::FrameCurrent, zFightTerrainAdjust bias) - a below-grade eye
gets NO terrain, so retail shows sky through the cellar door.

We inherited WB's frame-global cull DISABLE (WB GameScene.cs:841 - an
editor camera goes underground by design) and TerrainModernRenderer.Draw
set no cull state of its own -> terrain rasterized both sides. From a
below-grade eye every aperture sight-ray RISES, so the only 'terrain'
it can see is the grade sheet's underside - which painted the exit-door
aperture (the landscape slice's 2D NDC clip planes (nx,ny,0,dw) have no
depth axis and cannot exclude between-eye-and-portal geometry) and slid
off the door exactly as the eye crossed grade. Membership/viewer was
exonerated by the harness in the previous commit.

Fix: TerrainModernRenderer.Draw owns its cull state (the 7th
self-contained-GL-state instance): Enable(CullFace) + CullFace(Back) +
FrontFace(Ccw), set -> draw -> restore the frame-global CW + cull-off
baseline. GL backface culling evaluates retail's per-triangle eye-side
predicate at rasterization; no shader change.

Pins:
- LandblockMeshTests.Build_AllTriangles_WindCounterClockwiseInWorldXY:
  every emitted triangle CCW in world XY across both FSplitNESW split
  directions - the winding invariant culling depends on.
- TerrainCullOrientationTests: under the production camera convention
  (LookAt up=+Z, Numerics perspective) an up-facing triangle winds CCW
  in window space from above (kept) and CW from below (culled) - guards
  FrontFace inversion, which would blank terrain from above.

Oracle note: retail's through-portal clip has NO portal-face near plane
(PView::GetClip / Render::set_view install edge planes only); nearer-
than-portal exclusion comes from the eye-side cull + cell-level
admission. No register row: this PORTS the retail mechanism, retiring
an undocumented WB-heritage deviation.

Gate pending: cellar climb (grass window gone) + outdoor sanity glance
(terrain intact from above).

d208002bf8 fix #131 (root cause 4, structurally forced): look-in cells draw their DYNAMICS - the town portal is a server object in the hall's porch cell
The headless replay of the captured indoor frame proved the look-in flood ADMITS the porch 0x017A (Diagnostic_LookInFlood_AdmitsHallPorchFromCottage: 14 cells). So the portal (a SERVER object - the teleport proves it - with ParentCellId 0xA9B4017A) routes to partition.Dynamics and draws NOWHERE under an interior root: dynamics-last viewcone-culls it (the main cone has no look-in cells) and post-seal it would z-fail beyond the root's door plane (the #118 lesson). This is AP-33's own recorded deferral - 'look-in DYNAMICS are not drawn' - the deferred case was the most-stared-at object in town. Outdoors the merge path puts the porch in the main cone -> drawn -> 'appears when I walk out'.

Fix: DrawBuildingLookIns pass 2 draws look-in-cell dynamics with the statics (whole, AP-33 over-include) and their emitters ride the same DrawCellParticles call. No double-draw: dynamics-last keeps culling them; DrawDynamicsParticles only sees its cone survivors. #124 CLOSED by user gate same session. AP-33 row updated.

47f32cd45c fix #131 (root cause): look-in cells draw their emitters - the cell-particles pass was missing from the #124 sub-pass
The teleport capture pinned it: walking into the portal flipped pCell to 0xA9B4017A - the hall's PORCH EnvCell. The swirl emitter is owned by a static inside another building's cell. Outdoors the merge path runs the main per-cell pass incl. DrawCellParticles -> visible; under an interior root the #124 look-in sub-pass drew shells + statics but had no cell-particles call. Retail's nested DrawCells draws objects WITH their emitters (DrawObjCellForDummies pc:432878+). Fix: DrawBuildingLookIns pass 2 invokes DrawCellParticles per look-in cell with its static bucket. The owner-cone verdicts were geometrically correct all along (0xC0A9B462 = a porch torch); fixes 1-2 were real-but-adjacent (the unattached pass plugs an independent hole; the alpha deferral fixed #132).

87afbc0a42 fix #132 (outdoor sibling): outdoor attached scene emitters move to the post-frame pass; sharpen the #131 probe
User gate on 20d1730: the candle is FIXED indoors ("now the candle
light is visible when I'm in the house when it is in front of the
opening") and the OUTDOOR sibling surfaced exactly as AP-34 recorded
("when I go out it is not showing unless I turn so the angle doesn't
put it in front of the opening"): under an OUTDOOR root the merged
building interiors draw AFTER the landscape stage (DrawEnvCellShells),
so a slice-drawn flame is overpainted by a punched aperture's interior
behind it.

Fix: outdoor roots SKIP the late-slice Scene-particle draw; attached
outdoor-static scene emitters draw in the POST-FRAME pass alongside the
T3 unattached pass, where depth is complete and flames composite
correctly against interiors. The owner-id set carries over from the
late slice (single full-screen slice outdoors); cell-pass and
dynamics-pass emitters keep their own passes (their owners are never in
the outdoor-static id set - no double-draw). Interior roots keep the
late-slice draw (their stage ends with the clear + seal discipline).
AP-34 row updated (the outdoor residual is now covered; the remaining
residual is translucent MESH batches within stage draw calls).

Portal swirl (#131): the user's "same results" on 20d1730 KILLS the
look-in-erasure hypothesis for the portal - the mesh now draws after
the look-ins and is still missing indoors. No further speculative fix;
the [outstage] probe now prints each outside-stage dynamic's
SourceGfxObjOrSetupId (portals have distinctive setups) and
[outstage-pt] lists up to 12 distinct UNMATCHED attached emitter owner
ids - the next capture identifies whether the portal entity reaches the
through-door draw at all, and where its emitters point.

20d17304d7 fix #131+#132: landscape translucents drawn AFTER the #124 look-ins (FlushAlphaList deferral)
The user's screenshot pair re-attributed both reports to ONE mechanism -
a compositing gap in the #124 look-in sub-pass:
- #131: the portal swirl (a TRANSLUCENT MESH, not only particles) stood
  exactly in front of the hall's doorway. The slice drew it BEFORE the
  look-in sub-pass; translucents write no depth, so the hall's interior
  - drawn into its far-Z-punched aperture - overpainted the swirl.
  Outdoors the look-ins are the post-stage merge path, so the swirl
  survives ("stepping out it pops into existence").
- #132: the candle/lantern flame is an attached emitter in the slice's
  Scene-particle pass - same pre-look-in placement, same erasure
  whenever "the opening through a house" sat behind it; against a wall
  nothing overdraws it. Background-dependence explained exactly.

Retail cannot exhibit this class: every alpha draw of the landscape
stage is collected and flushed ONCE after LScape::draw
(D3DPolyRender::FlushAlphaList, PView::DrawCells pc:432722) - i.e.
after all building look-ins.

Port (the two-phase split): DrawLandscapeThroughOutsideView now runs
EARLY per slice (sky, terrain, outdoor STATIC meshes - the look-in
punches need their depth to mark against, the #117 lesson), then the
#124 look-ins, then LATE per slice (outside-stage dynamics' meshes +
ALL attached scene particles + weather + SkyPostScene), then the #131
unattached pass. New RetailPViewLandscapeLateSliceContext carries the
dynamics survivors + the particle-owner set (statics + dynamics cone
survivors). GameWindow's slice handler split accordingly. Outdoor
roots: no look-ins live in the stage, so the net order is unchanged
(zero behavior change outdoors).

Register: AP-34 added - the two-phase split vs retail's single
deferred flush, with the residuals recorded (outdoor-root slice
particles still draw before merged building interiors - the unreported
outdoor sibling; building exteriors' own translucent batches draw
early).

The earlier #131 unattached-emitter pass (1d3f9a8) remains - it fixes
an independent hole (that class had NO indoor pass at all) - and now
runs at the end of the late phase.

1d3f9a8c97 fix #131: unattached emitters had NO particle pass under interior roots
The user's capture run + a code read pinned it in one step: every
particle pass under an interior root is id-filtered (the landscape
slice's Scene pass, the per-cell pass, and the dynamics pass all
require AttachedObjectId != 0 plus owner-set membership). An UNATTACHED
emitter - AttachedObjectId == 0: portal swirls, campfires, ground
effects anchored at a position - drew NOWHERE when the viewer root was
interior. The outdoor root has the dedicated T3 pass for exactly this
class (its own comment records that "unattached ones had NO pass on
outdoor-node frames"); the identical hole on interior-root frames was
never plugged. Walking out flips to the outdoor root and the T3 pass
picks the swirl up - "appears when I walk out again", verbatim.

The [outstage] capture corroborated the rest of the chain healthy
under the interior root: outside-stage routing correct, cone PASS for
the portal-family dynamics, 57 attached emitters matched and drawn
through the doorway. Only the unattached class was orphaned.

Fix: RetailPViewDrawContext.DrawUnattachedSceneParticles - invoked ONCE
per interior-root frame at the END of the landscape stage:
- pre-clear, because drawn after the depth clear + seals an outdoor
  emitter beyond the door plane z-fails against the seal's door-plane
  stamp;
- after the #124 look-in sub-pass, so swirls blend over far-building
  interiors;
- once per frame, not per slice - alpha particles must not double-draw
  (the #121 lesson);
- mutually exclusive with the outdoor T3 pass by root kind (interior
  invokes this; outdoor keeps T3).

Residual (documented in the issue): unattached INDOOR emitters now draw
pre-clear and get overpainted by the room's shells - the same
invisibility they had before this fix; the proper per-emitter cell
classification is a future port.

[outstage-pt] probe extended with the unattached emitter count (the
probe's blind spot was exactly where the bug hid).

77cef4cd86 fix #124: interior-root building look-ins as a landscape-stage sub-pass
From inside a building, looking out at ANOTHER building with an opening
showed its back walls missing (see-through to the world): per-building
look-in floods only ran for outdoor roots; under an interior root the
far building's interior never flooded.

Decomp anchor (named-retail, this session's read): retail runs the
look-in INSIDE the landscape stage for ANY root - LScape::draw is the
FIRST call of PView::DrawCells' outside-view branch (pc:432719),
strictly BEFORE the depth clear (pc:432732) and the exit-portal seals
(pc:432785). ConstructView(CBldPortal) (0x005a59a0) clips each aperture
via GetClip against the INSTALLED view - the accumulated doorway region
when looked into from inside - and build_draw_portals_only pass 1
far-Z punches ALL apertures before pass 2 floods + draws any interior
cell. The nested DrawCells has an empty outside view (PView ctor
draw_landscape=0): no recursive landscape/clear/seal.

Port:
- GameWindow's per-building gather (frustum pre-gate on
  Building.PortalBounds) now runs for interior roots too; the root's
  own doorway self-excludes via the seed eye-side test (the eye is on
  its interior side).
- PortalVisibilityBuilder.BuildFromExterior/ConstructViewBuilding gain
  seedRegion - the installed-view clip: interior-root look-ins seed
  against the OutsideView polygons (a building not visible through the
  doorway never floods); null = full screen (outdoor roots unchanged).
- RetailPViewRenderer.DrawBuildingLookIns: a landscape-stage sub-pass
  (before ClearDepthForInterior + seals) - per building, punch ALL
  apertures (new DrawLookInPortalPunch callback, always forceFarZ=true,
  closing the ISSUES "forceFarZ keys on root kind, under-punches" gap),
  then draw the flooded cells' shells + statics far->near. Look-in
  frames are NEVER merged into the main frame: a merged cell would draw
  post-clear and z-fail against the root's seal (the old ledger
  portShape sketch was wrong on this point).
- Look-in cells join the Prepare + partition set so shells have batches
  and statics route to ByCell (consumed only by the sub-pass; the main
  cell-object pass iterates the main flood's cells).

Register: AP-33 added in the same commit - look-in statics draw WHOLE
(no per-part viewcone; over-include is the safe direction) and look-in
DYNAMICS are deferred (an NPC inside a far building stays invisible -
retail draws objects per overlapped cell in the landscape stage).

Pins: Issue124LookInSeedRegionTests on the real corner-building door -
a seed region containing the aperture floods (and never more than the
full-screen seed), a disjoint region floods NOTHING, and an
interior-side eye never seeds its own exit portal.

5135066733 fix #130 (the real strip): drawn-shell lift vs draw-space portal consumers
The user's re-gate refuted the scissor fix as THE strip (6c4b6d6 was a
real but sub-pixel under-coverage): the strip survived, screenshot at a
doorway, full width of the opening, top edge only, "very subtle".

Root cause (pinned by Issue130DoorwayStripTests.UnliftedGate_*): the
+0.02 m shell render lift. Cell shells DRAW 2 cm above the dat origin
(z-fight vs coplanar terrain); f35cb8b (the #119-residual fix,
2026-06-11) deliberately reverted the VISIBILITY graph to the physics
(unlifted) transform - but the OutsideView color gate (terrain/sky/
scissor through the doorway) and the seal/punch depth fans are
DRAW-space consumers and kept projecting the unlifted polygons. The
drawn lintel therefore sits one lift-projection above the gate's top
edge - measured 6.7 px at a 2.4 m doorway - and that band never
receives terrain/sky color while the seal also stamps 2 cm low.
A regression from f35cb8b, NOT from the W=0 clip port (987313a stays
exonerated). Vertical aperture edges are immune (the lift slides them
along themselves) - top edge only, exactly as reported; explains the
"also NOW" timing precisely.

Fix - draw space draws lifted, visibility stays physics (the f35cb8b
invariant, now symmetric):
- PortalVisibilityBuilder.Build gains drawLiftZ: the exit-portal branch
  projects the OutsideView region with the lifted transform; flood
  admission, side tests, and CellViews are untouched (default 0 keeps
  every existing visibility test bit-identical).
- The seal/punch fans (DrawRetailPViewPortalDepthWrite) lift their
  world verts to the drawn shell's space.
- One shared constant PortalVisibilityBuilder.ShellDrawLiftZ feeds the
  shell registration (GameWindow:5604), the gate, and the fans.

Register: AP-32 ADDED - the +0.02 lift had NO row (a pre-register
deviation the 2026-06-12 sweep missed). The row records the split
invariant both ways: a draw-space consumer that forgets the lift
re-opens the #130 strip; a visibility consumer that picks the lifted
transform re-opens the #119-residual side-cull.

Pins: the lifted gate covers the drawn (lifted) aperture to 0.00 px
across the 147-combo sweep; the unlifted gate shows the 6.7 px strip
(sensitivity proof - if the lift is ever removed, this test says the
drawLiftZ plumbing can go too).

4ba714835d fix #129: cap the punch mark bias's eye-space reach (was unbounded at distance)
The user's "doors/doorways leak through terrain and houses over a
landblock" is the #117 mark-pass bias evaluated in the wrong space.

Mechanism (confirmed analytically, Issue129PunchBiasTests): the punch's
pass-A stencil mark biased the aperture fan toward the viewer by a
CONSTANT 0.0005 NDC. NDC depth is non-linear - a constant NDC bias b
spans ~= b*d^2*(f-n)/(f*n) meters of eye depth at eye distance d. With
retail's znear 0.1 (d4b5c71) that is 0.125 m at 5 m but ~190 m at one
landblock: every hill/house in front of a distant aperture passed the
LEQUAL mark and was far-Z punched -> door-shaped leak through the
occluder. This is exactly the risk AD-18's register row recorded
("an occluder within ~bias in front of a distant aperture gets punched
through") - the symptom-scan rule found it before instrumentation.

Fix: cap the bias's EYE-SPACE span at 0.5 m -
  biasNdc(d) = min(0.0005, capMeters * near / d^2)
in the mark-pass vertex shader (clipPos.w = eye depth), CPU-mirrored as
PortalDepthMaskRenderer.MarkBiasNdc for tests. Below the ~10 m
crossover the constant-NDC term is smaller and wins - bit-identical to
the T5-validated close-range behavior, so the #108 grass coverage that
justified the bias is untouched. Beyond it the punch can never reach an
occluder more than 0.5 m in front of the aperture plane.

Pins (Issue129PunchBiasTests): the old form spans >100 m of eye depth
at a landblock (the leak, kept as documentation of the refuted shape);
the capped form stays <= 0.5 m at every distance 1-400 m and matches
the validated constant bit-for-bit below 10 m.

AD-18 register row updated in the same commit (bias description + the
#129 closure + the residual risk note: door-hugging geometry beyond the
0.5 m cap at >10 m viewing range re-occludes - the cap constant is the
tuning knob if the gate shows residue).

6c4b6d64d9 fix #130: doorway-slice scissor cut the aperture's top/right pixel row
The user's "thin strip of background color along the TOP outer edge of a
doorway, looking out from inside" is the landscape-slice scissor box, not
the W=0 clip port.

Mechanism (pinned headlessly, Issue130DoorwayStripTests, 147 eye/gaze
combos at the real Holtburg A9B4 0x0170 exit door):
- BeginDoorwayScissor converted the slice NDC AABB to pixels as
  Floor(origin) + Ceiling(size). The far edge floor(min)+ceil(max-min)
  lands up to ONE PIXEL SHORT of the true top/right edge at unlucky
  fractional alignments (captured: top edge y=0.7938 @1080p -> row 968
  cut; right edge column 1296 @1920 cut).
- The scissor brackets the ENTIRE landscape slice (sky, terrain, outdoor
  statics, weather). The exit-portal SEAL stamps the full raw aperture at
  true depth and the shell wall ends at the aperture edge, so the cut row
  never receives any color write -> clear color, flickering with eye
  movement as the fractional alignment shifts.
- This violated AD-17's own invariant (over-inclusion is safe,
  UNDER-inclusion is the bug class). No register change: the fix restores
  the row's documented doctrine.

Lead 1 (987313a W=0 clip port regression) REFUTED by the same harness:
the CPU polygon pipeline (ProjectToClip -> ClipToRegion merges ->
ClipPlaneSet planes) is sub-pixel exact against the raw aperture
projection (worst 0.54 px, 0.00 px aligned). For an all-in-front doorway
polygon the port is bit-identical to the old 1e-4 path by construction.
The EyeInsidePortalOpening rescue stays deleted.

Fix: conservative outer bound floor(min)/ceil(max) extracted to
NdcScissorRect.ToPixels (GL-free; containment property proven in the
header comment); BeginDoorwayScissor delegates.

Pins:
- NdcScissorRectTests: center-inside containment across 251 fractional
  alignments x 2 framebuffer sizes + both captured regression cases.
- Issue130DoorwayStripTests: production flood + assembler at the real
  exit door; asserts the scissor never cuts a plane-admitted fragment
  (worstScissorGap 0.00 px post-fix, was 10.8 px capped) and the CPU
  pipeline stays sub-pixel exact (canary 1.2 px).

0cb97aa594 UN-2 RESOLVED: GetMaxSpeed x4 is byte-verified retail; doc-comment was the misread
The register's UN-2 row recorded a contradiction: the GetMaxSpeed XML doc
claimed the bare run rate was retail-correct (~5.9 m/s catch-up, calling
the xRunAnimSpeed multiply a misread), while the implementation multiplied
by RunAnimSpeed citing ACE. Settled against the binary, not the pseudo-C:

- BN pseudo-C (acclient_2013_pseudo_c.txt:305127) renders get_max_speed as
  void with a bare `this->my_run_rate;` because it DROPS x87 instructions.
- Disassembling the PDB-matched v11.4186 binary at VA 0x00527cb0: all THREE
  return paths end `fld <rate>; fmul dword ptr [0x007C8918]; ret`, and the
  .rdata dword at 0x007C8918 is 4.0f. Sibling get_adjusted_max_speed
  (0x00527d00) carries the same trailing fmul. Verifier committed at
  tools/verify_un2_fmul.py (PE parse + byte decode, rerunnable).
- Retail paths: weenie null -> 1.0 x4; InqRunRate ok -> queried x4;
  InqRunRate failed -> my_run_rate x4. ACE MotionInterp.cs:665-676 matches.

Changes:
- Doc-comment rewritten: the implementation is retail-correct; the catch-up
  speed 2 x get_max_speed ~= 23.5 m/s at run 200 IS retail. The 1-Hz
  remote-blip symptom the old comment attributed to this multiply is
  therefore UNEXPLAINED by it (if it recurs: #41 family, not this).
- Weenie-null path aligned to retail's LITERAL 1.0 default (was MyRunRate).
- Tests re-pinned to the three retail paths (the old NoWeenie test pinned
  the non-retail fallback).
- Register: UN-2 row deleted per the retire rule (6 -> 5 UN rows);
  shortlist renumbered.

This is the 2nd confirmed instance of the BN x87-dropout artifact class
(memory: feedback_bn_decomp_field_names) deciding a register row.

be03146e30 #112 ROOT CAUSE: outdoor-seed pick lacked retail's growing-array walk - threshold tick-skip became absorbing
The instrumented capture (cottage-112-capture1.log) + dat replay pinned
the transparent-cottage mechanism end to end:

1. The A9B3 cottage's entry cell 0x104 is a 0.22 m-wide THRESHOLD band
   (x 184.68->184.46 at y~82). A running player (~13-16 cm/tick at
   30 Hz) can cross it BETWEEN two physics ticks - the tick where the
   centre is inside 0x104 never happens.
2. Our outdoor-seed branch ran CheckBuildingTransit over a landcell
   snapshot and STOPPED - building-admitted entry cells were never
   expanded. The tick after the skip (centre in 0x100, a deep room not
   building-portal-adjacent) found no containing candidate -> the pick
   kept the outdoor landcell FOREVER (absorbing): the user walked the
   whole interior classified outdoor (render faithfully drew an outdoor
   frame = transparent walls), promoting only on touching
   portal-adjacent 0x102's own volume minutes later (captured:
   0xA9B3003C -> 0xA9B30102 with no transitions in between).
3. Retail cannot strand: CObjCell::find_cell_list (0x0052b4e0) runs ONE
   growing-array walk for EVERY seed (0052b576-0052b5ab,
   cells[i]->find_transit_cells vtable dispatch over the GROWING array)
   - the landcell's building bridge admits 0x104 (the foot sphere still
   overlaps the band one tick after the skip) and the walk expands
   0x104's portals to 0x100 where containment wins. Recovery fires one
   tick after any skip.

Fix: BuildCellSetAndPickContaining now runs retail's single growing
walk for both seeds with per-cell-type dispatch (landcells ->
CLandCell::find_transit_cells 0x00533800 -> CSortCell 0x00534060 ->
check_building_transit 0x0052c5d0; envcells -> FindTransitCellsSphere
with the straddle gate + once-per-walk outside add). The old indoor
branch behavior is preserved (seed at index 0, hysteresis, straddle-
gated outdoor pick); the outdoor branch gains the expansion + the
indoor branch gains the retail landcell bridge dispatch for
straddle-admitted landcells.

Pins (dat-backed, Issue112MembershipTests): tick-skip recovery one tick
past the threshold (RED pre-fix); run-speed entry replay across tick
phases never strands outdoor; threshold-gap outdoor-seed keeps outdoor
(over-fix guard); entry-walk replay diagnostic prints the full
promotion chain (0x3C -> 0x104 -> 0x100 -> 0x103 -> 0x100 -> 0x102).

6a9b529113 #119: entity bounds from dat vertex data - works for every case, not just multi-part
The 1ca412d part-offset expansion fixed the staircase but still rested
on the 5 m promise one level down: a SINGLE part whose mesh extends
more than 5 m from its own origin (offset 0 -> box +-5 m) keeps the
gaze-dependent vanish. Per the user's mandate ("it must work for every
case"), the bound now derives from the dat VERTEX data - the same
vertices that get drawn - so no synthetic containment promise remains.

Oracle context (read this session): retail has NO whole-entity
visibility volume - CPhysicsPart::Draw (0x0050d7a0) viewcone-checks
each part's dat-authored CGfxObj.drawing_sphere at the part's own
world position (RenderDeviceD3D::DrawMesh 0x005a0860). Retail's bound
IS data; ours was a promise. Our per-ENTITY granularity stays (a
deliberate batching-era choice, WB-owned per the inventory) but the
volume is now data-derived and conservative: visually identical by
construction, never culls what retail would draw.

- GfxObjBounds: per-GfxObj vertex AABB, cached by id (parts repeat
  heavily); LocalBoundsAccumulator: union of part-transformed AABB
  corners (conservative-correct under any affine transform).
- WorldEntity.SetLocalBounds + RefreshAabb preferred path: rotate the
  root-local bounds' 8 corners into world axes + DefaultAabbRadius
  margin (absorbs animated-pose drift vs the rest-pose bounds; keeps
  small objects at their historical box size). Offset heuristic stays
  as the fallback for boundless fixtures.
- All four hydration sites wired (outdoor stabs, scenery incl. baked
  scale, interior cell statics, server live spawns).

Tests: tall-single-part coverage (the case 1ca412d could not see),
rotation-following, accumulator union. Suites: App 246+1skip / Core

1ca412d07b #119: entity bounds must cover the parts - the gaze-dependent staircase vanish
User re-gate after 2163308/987313a: run-from-town stairs FIXED, barrel
GONE - but the stairs still vanish by VIEWING ANGLE (visible climbing
down, gone climbing up; same at the tower top). The gate3 probe data
exonerates everything downstream: the entity always draws with correct
batches when it reaches the dispatcher (cache hit:119, restZ correct,
zero WALK-REJECTs, never clip-culled) - so the vanish lives in the one
gaze-dependent gate the probe cannot see: the bounds-based cullers.

WorldEntity.RefreshAabb was a fixed +-5 m box around the entity ANCHOR.
The staircase's 43 parts spiral 15 m ABOVE the anchor, and BOTH
visibility gates derive from the box: the dispatcher's per-entity
frustum cull AND RetailPViewRenderer.EntitySphere (the viewcone sphere
= this box's bounding sphere). Looking up the spiral put the anchor's
neighborhood out of view -> the whole entity culled while 15 m of it
stood in front of the camera; looking down kept the anchor in view ->
visible. Exactly the reported asymmetry.

Fix: expand the box by the largest MeshRef part-translation magnitude
(rotation-invariant, so entity.Rotation needs no handling; identity-
part entities get offset 0 - behavior unchanged; scenery scale is
already baked into the part transforms).
