User-reported: logging in at a non-Holtburg position sometimes showed
stabs/scenery floating in the wrong place. Root-caused via a threading/
lifecycle trace, not inference: WorldSession transitions to InWorld
immediately after the login handshake (WorldSession.cs:608) — well
before the player's own spawn CreateObject (which carries their real
position) has arrived over the network. The streaming gate's old
condition (`!IsLiveModeWaitingForLogin || liveInWorld`) opened the
instant InWorld fired, letting the background streaming worker
(LandblockStreamer's dedicated Thread) build real landblocks using
whatever _liveCenterX/Y held at that moment — the Holtburg startup
placeholder, not a "not known yet" sentinel. Landblocks that started
building in that window bake their world offset from that placeholder
at build time; if their build was still in flight when the real spawn
arrived and recentered the world (ForceReloadWindow, which only
unloads already-RESIDENT landblocks), they finished and got applied
anyway — stale-positioned geometry landing wherever the guess put it
relative to whatever streamed in afterward with the corrected center.
Confirmed with the user this wasn't "wrong placeholder, need a better
one" — any placeholder racing against the real answer reproduces the
same bug. The fix removes the race instead: StreamingReadinessGate
.ShouldStream requires an explicit liveCenterKnown flag (true only once
the player's own spawn has been processed) in addition to liveInWorld.
Nothing streams in live mode until the real position is confirmed — no
placeholder value is ever acted on. Preserves the #106 gate-3 fix this
gate originally existed for (auto-entry waits for terrain under the
spawn; terrain streaming must not wait for chase mode in turn, or the
two deadlock) since liveCenterKnown becomes true independently of chase
mode, driven purely by the spawn packet's arrival.
The stricter render gate (GameWindow.cs:9596, hides ALL world geometry
until chase mode engages, no relaxation) already provided a partial
safety net and is unchanged — this fix stops the stale geometry from
ever being built, rather than relying on the render gate to hide it
until the reveal.

Found while investigating #189 (missing fountain/candle particles):
reverting the A7.L1 light-carrier hydration fix (9ebb2060) made the
Town Network fountain's water-spray particle work again, which didn't
fit the earlier dat-truth finding that the fountain's own entity was
never touched by that fix. Traced with ACDREAM_DUMP_ENTITY: the
fountain's hydrated entity.Id shifted between reverted (0x400007F8)
and fixed (0x40000815) builds — a 29-id delta matching the extra
mesh-less light carriers the A7.L1 fix now keeps alive earlier in the
same landblock's hydration pass.
Root cause: GameWindow's interior-entity id scheme
(interiorIdBase + localCounter, "0x40XXYY##") reserves only 8 bits
(256 values) for a landblock's ENTIRE interior static population — a
residual explicitly flagged in the #119 fix's own comment ("counter
overflow past 0xFF still bleeds into the lbY byte"). The Town Network
hub (205 cells, one landblock) already sat at 248 before A7.L1; the
light fix pushed it to 277, past the boundary. 0x40000815 decodes as
landblock Y=0x08 — NOT this dungeon's true Y=0x07 — the exact #119
cross-landblock aliasing bug, reincarnated by entity count instead of
a computation bug. EntityScriptActivator keys particle-script
instances by entity.Id directly (no landblock-hint disambiguation
unlike the #119 batch cache), so the aliased id silently broke the
fountain's script tracking.
Fix: AcDream.Core.World.InteriorEntityIdAllocator widens the counter
8->12 bits (256->4096) by shrinking the fixed class prefix from a
full byte (0x40) to its top nibble (0x4_) — verified safe against
every entity.Id classification check in GameWindow (none decode X/Y
back out, they only check thresholds/prefixes). Added a loud
one-time [id-overflow] log if a landblock ever exceeds the new
budget, so this class of bug can never hide silently again.

Root-caused via dat-truth inspection, not inference: the A7.L1 visible-
cell scoping fix (previous commit) had zero visual effect because the
Town Network fountain room (cell 0x00070144) registers ZERO lights of
its own — confirmed directly against the dat, not assumed. The room's
one dat-authored fixture, Setup 0x02000365 (a ceiling light 5m above the
fountain, warm color, intensity 100), has a single visual part that is a
#136-class runtime-hidden marker. Flattened mesh ref count: 0. GameWindow
's per-stab hydration loop treated meshRefs.Count==0 as "doesn't exist"
and dropped the whole entity before the Setup's Lights were ever read —
so a mesh-less "light attach point" fixture, a normal AC dat authoring
pattern, could never register. Retail's light registration (add_light,
CEnvCell::UnPack) is architecturally independent of a fixture's own mesh
visibility.
Fix: track the stab's Setup.Lights.Count alongside meshRefs during
hydration; keep the entity (with empty MeshRefs — nothing to draw, still
something to light) whenever either is nonzero. Extracted the decision
into EntityHydrationRules.ShouldKeepEntity (pure, unit-tested) since
GameWindow's hydration loop isn't independently testable. Confirmed no
downstream consumer assumes MeshRefs.Count >= 1 (WbDrawDispatcher already
guards on it before any indexing).

The Town Network hub (498 registered fixtures) starved the player's own
room: BuildPointLightSnapshot's player-nearest-128 cap sorts by raw
Euclidean distance, which isn't a reliable proxy for "same room" in a
dense maze — a fixture on the other side of a wall can be geometrically
closer than the room's own torches and win the cap. LightSource.CellId
tagging and the [indoor-light] membership probe already existed from the
c500912b/#176 arc; the missing piece was a candidacy filter.
BuildPointLightSnapshot(playerWorldPos, visibleCells) now narrows
candidates to the frame's actual visible cells before the existing
dynamics-first player-nearest cap runs (cell-less lights, e.g. the viewer
fill, always included). GameWindow feeds LAST FRAME's already-rendered
RetailPViewFrameResult.DrawableCells — one frame of latency instead of
re-threading a mid-DrawInside callback, which was the exact mechanism
(c500912b) that caused the earlier #176 seam-floor flicker regression.
The distance-sort anchor stays the player, unchanged.
AP-85 updated in place (third revision) rather than adding a new row —
same underlying divergence, now with the render-visibility approximation
of retail's true DBObj-load/flush-bounded resident registry documented
alongside its residual risk (one unscoped frame on portal re-entry).

Lands the fading-secret-door feature and fixes the door "flip-back" that
surfaced while testing it.
#188 — fading-wall doors (e.g. "Pedestal Weak Spot") fade their wall part
out via TransparentPartHook instead of swinging:
- TranslucencyHookSink consumes TransparentPartHook -> TranslucencyFadeManager
(per-(entity,part) linear translucency ramp; holds at End frame).
- WbDrawDispatcher: new per-instance alpha SSBO (binding 7); ClassifyBatches
takes opacityMultiplier (1 - translucency, per CMaterial::SetTranslucencySimple
0x005396f0) forcing AlphaBlend; fully-invisible parts skipped.
- mesh_modern.vert/.frag: binding-7 InstanceAlphaBuf -> vOpacityMultiplier ->
FragColor.a *= vOpacityMultiplier.
- Register AP-89: the fade multiplies sampled texture alpha, not a separate
D3D9 material alpha channel (observably identical for texture-alpha==1 surfaces).
Door flip-back fix (affected BOTH #188 fading walls AND #187 sliding doors): a
door/wall that finished opening holds a single unchanging frame, so the
uncommitted IsEntityCurrentlyMoving cache-bypass narrowing dropped it onto the
Tier-1 static cache -- which only remembers the REST pose + opacity 1.0 --
snapping it visually shut/opaque while physics stayed open. Reverted that
narrowing: every Sequencer entity stays on the per-frame path (live pose + live
fade opacity), the known-good pre-optimization behavior. The per-frame CPU cost
that narrowing chased was a Debug-build artifact -- Release is GPU-bound
(~200 fps in Sawato, measured), so the unconditional add is free where it
matters. Left a code comment barring re-introduction.
Tests: full Core suite green (2649 passed, 2 skipped). Live visual gate PASSED --
both fading-wall and sliding doors hold open.

Root cause (live capture #3 + code): GameWindow's per-part landblock shadow
registration used a synthetic part-id `entity.Id * 256u + partIndex` that
OVERFLOWS uint32 for class-prefixed landblock ids (0x40/0x80/0xC0...). The << 8
drops the prefix byte, so different-class entities sharing the low 24 bits
collide on ONE shadow part-id and Register's deregister-then-insert silently
overwrites one entity's collision geometry. Landblock 0xF682 had 23 such
collisions incl. the stair runs (0xF6822100 <- {0x40F68221, 0xC0F68221}, ...),
so 3 mid-staircase steps rendered but had no collision -> the player floats into
the hole and the (faithful) PrecipiceSlide wedge fires = the 'invisible wall
half-way up the stairs'.
Fix (Option A, retail-faithful): register each multi-part landblock entity via
ShadowObjectRegistry.RegisterMultiPart under its UNIQUE 32-bit entity.Id
(retail CPhysicsObj::add_shadows_to_cells 0x00514ae0 -> CPartArray::AddPartsShadow
- one object, a part array; no synthetic per-part id). New testable builder
ShadowShapeBuilder.FromLandblockBspParts decomposes each MeshRef.PartTransform to
local pos/rot/scale; RegisterMultiPart reconstructs the identical world placement.
Building shells stay excluded (building channel); the Setup cyl/sphere path is
unchanged (runs only when entityBsp==0, retail BSP-xor-cyl dispatch). Despawn is
landblock-scoped (RemoveLandblock by cell prefix), so the id change is safe.

RegisterMultiPart keeps both; builder). Issue185OutdoorStairsSeamReplayTests

Completes the TS-3 stub (the deferred 'full physics port'):
- ValidateTransition: the fsf increment/reset ladder + the fsf>=3 upward-contact-plane
manufacture (retail validate_transition 0x0050aa70 pc:272625-656; ACE Transition.cs:
1029-1061). Runs after acdream's fused contact block (structural adaptation preserving
the L.2.3c/L.2.4/A6.P3 contact-retention divergences), deriving retail's _redo as
cleanAdvance || OnWalkable — a grounded wall-slide is not a stuck-fall.
- The sweep-loop fsf early-out (retail find_valid_position pc:273745 / ACE :587): stop
as soon as fsf != 0, so a later advancing sub-step can't reset it in the same frame
(load-bearing — without it the counter never escalates across frames).
- ObjectInfo.MoverHasGravity gate (pc:272625).
- PhysicsEngine: seed ci.fsf from the body's Stationary* bits AFTER InitPath
(retail transition() pc:280940-947); writeback publishes body.FramesStationaryFall +
encodes the Stationary* bits (co-located with the fsf compute so the round-trip is
self-contained in Core; retail encodes in handle_all_collisions — register note).
Tests: FramesStationaryFallTests — an airborne jump wedged under an overhead creature
escalates fsf 0->1->2->3 and at fsf 3 manufactures the UP plane (grounded 'glide onto
the crowd top'); a grounded wall-slide never accumulates fsf. Core 2609/0.

Humanoid creatures/players collide as body Spheres (ShadowShapeBuilder emits
Sphere-type shadows for a Setup with Spheres + no CylSpheres), so player-vs-monster
crowd contact ran through Transition.SphereCollision — a hand-rolled 3-D wall-slide
(register TS-45), NOT a port of retail CSphere::intersects_sphere. It shaved no eps,
force-pushed each contact RADIALLY to a fixed combinedR+1cm shell, ignored the head
sphere, and always returned Slid. In a crowd the opposing radial de-penetration
pushes from neighbours fight each other -> the player wedges and can't wiggle free
(the user's live report).

The user's retail axiom (camera rock steady pressed into walls) vs our measured wall-press wander (~0.5mm/frame limit cycle, headless pin Issue181WallPressEquilibriumTests) sent us back to the decomp. Ghidra (clean, vs the BN x87 mush): retail VIEWERS subdivide the sweep into EXACTLY radius-length steps anchored at the start (offsetPerStep = offset*r/len, numSteps = floor(len/r)+1) with the final step recomputed mid-loop as the exact remainder (find_transitional_position 0x0050bdf0), and the negligible-offset abort is NON-viewer-only. Ours used ceil equal-slices for everything and aborted viewers too. Ported faithfully (pseudocode docs/research/2026-07-06-viewer-step-subdivision-pseudocode.md); non-viewer stepping already matched (TRANSITIONAL_PERCENT_OF_RADIUS=1.0).
Measurement: the wall-press limit cycle is UNCHANGED by the port (537.8um avg; a bit-exact 12-frame cycle: ~130um/frame inward creep x11 then a 2.6mm snap). With adjust_to_plane + adjust_sphere_to_poly now also Ghidra-verified faithful, the residual mm cycle is likely retail-class plateau physics - invisible at retail's 60fps vsync, tear-interleaved into visible stripes at our ~1500fps unsynced. The decisive user test: VSync ON (Settings/F11). Fallback discriminator: cdb-trace retail's viewer at a wall press. Suites green (Core 2600 / App 733 / UI 425 / Net 385).

The autonomous visual loop on the stateful-sought camera exposed the true
root of the #176 stripes: a ~19Hz SAWTOOTH. The sought re-extends ~3mm/frame
and the sweep silently passes while the 0.3m viewer sphere presses up to
~0.25m past the wall plane, then clips a whole transition step (~0.27m) back.
Headless replay against the real Facility Hub corridor BSP (0x8A020164, the
captured ray) reproduced it exactly: pre-fix, embedded targets passed
unclipped and the first detection stopped at the PREVIOUS STEP BOUNDARY,
tracking the target (eyeBack = s - 0.27).
Root cause: BSPQuery.AdjustToPlane - copied from ACE's BSPTree.cs port -
was structurally inverted and ALWAYS returned false (the touchTime==1 branch
re-placed the sphere at the unchanged check position; touchTime<1 iterated
doing nothing; the <0.02 convergence exit returned false). With the
PerfectClip exact-contact machinery dead, CollideWithPt always fell to the
bare Collided path and the transition reverted the colliding step whole.
ACE never noticed: PERFECT_CLIP (0x40) is a client camera flag the server
never exercises (feedback_bn_decomp_field_names class 3 - the retail binary
outranks ACE in branches ACE never runs). The pre-stateful camera flipped
1-step vs 2-step backoffs on mm drift - the measured pulledIn 0.27 <-> 0.53
of the original #176 strobe was step quantization all along.
Rewritten per the retail binary (pseudocode doc
docs/research/2026-07-06-adjust-to-plane-pseudocode.md):
- BSPTREE::adjust_to_plane (0x00539bf0): clearTime/hitTime bounds (0.0/1.0),
Phase 1 walks plane-touch times re-testing the whole tree (the tree test
feeds a DIFFERENT blocking poly back into the next iteration), Phase 2
binary-searches with the SHARED iteration counter, window < 0.02 =
CONVERGED, final commit = last known-clear time. Only failure = Phase-1
exhaustion.
- CPolygon::adjust_sphere_to_poly (0x00538170): early-out = plane-band test
at the START position (was: precise-poly test at the check position);
touch side = sign(dpPos)*radius (was: hard-coded -radius; ACE misdecoded
it as movement.LengthSquared() <= r^2); result unclamped per retail.
Replay pin Issue180CorridorSweepHysteresisReplayTests: short-of-touch
targets pass, past-touch targets always clip, and the clipped stop is the
CONSTANT surface-contact point (eyeBack 1.609 across the band; spread
< 0.03m) instead of tracking the target.

The #176 gate-2 failure ("stripes/triangles flickering when the camera
is pushed into walls; nothing when zoomed out") is NOT a render defect.
Isolation apparatus added this commit:
- ACDREAM_LIGHT_DEBUG shader modes (mesh_modern.vert/frag + uLightDebug
upload in EnvCellRenderer/WbDrawDispatcher): 1 = ambient-only,
2 = dynamics killed, 3 = raw vLit field (texture ignored). The
pattern SURVIVES mode 3 -> not texture; lives above the light data.
- ACDREAM_CLIP_DEBUG=1 (RenderingDiagnostics.ClipDebugNoShellTrim +
the EnvCellRenderer slot-fill gate): shell pass draws cells WHOLE
(retail's shape). Pattern survives -> the per-cell clip trim is
exonerated.
With every render suspect dead, an autonomous visual loop (synthetic
back-into-wall input + GDI window captures + the [flap-sweep] probe)
pinned the mechanism numerically: at a compressed moving boom the
camera-collision sweep is BISTABLE - consecutive sweeps with ~1.4 mm
input drift flip the first-contact solution 0.27 m along the boom
(pulledIn 0.27<->0.53, every ~5-10 frames, all 368k sweeps ok=True),
and at ~1700 fps unsynced every monitor refresh tear-interleaves the
two views = the stripe/hatch patterns. Filed as #180 with the retail
anchor: viewer_sought_position is STATEFUL (SmartBox 0x00452d75 feeds
the CURRENT swept viewer into CameraManager::UpdateCamera 0x00456660
and assigns the return to the sought, 0x00452d84) - the target
converges to the collided position instead of re-rolling the full
knife-edge ray per frame like our RetailChaseCamera does. SweepEye
itself ports update_viewer 0x00453ce0 faithfully and is exonerated.
Also recorded in #176: the site-A weenie light-registration leak (a
portal's I100 light stacked x2->x4 over one session as re-CreateObject
re-registered it under fresh entity ids).

mandatory-modern startup gate throws; AMD GPU rules out Nsight) killed
every double-draw suspect: ONE shell instance per seam cell at the
lifted z, no floor-coincident entity (portal entities sit at z=-12.05),
zero portal depth fans in the sealed Hub. What it caught instead: the
corridor floor's applied light set flipping wholesale with the flood.
Root cause: c500912b scoped BuildPointLightSnapshot by the per-frame
portal flood, on the research doc's gloss of CEnvCell::visible_cell_table
as "the portal-flood visible set". The named decomp refutes the gloss:
add_visible_cell (0x0052de40) DBObj-LOADS absent cells and inserts them;
a cell activation adds itself + its whole dat visible-cell list
(0x0052e228/0x0052e24a); entries leave only via the flush machinery.
It is the RESIDENT-cell registry - gaze can never remove a cell.
add_dynamic_lights (0x0052d410) walks the WHOLE table per frame
(caller 0x00452d30), and insert_light (0x0054d1b0) caps the pool by
distance to Render::player_pos (0x0054d1dd). Retail's pool is a function
of player position only. Ours followed the camera: turning changed the
flood (probe: 8..41 cells across one turn), the six intensity-100
under-room portal purples entered/left the pool, and the wedge blinked.
Fix: BuildPointLightSnapshot(playerWorldPos) collects ALL registered
(=resident) lit lights; over cap keeps dynamics FIRST (retail's separate
7-slot dynamic pool never competes with statics) then nearest-the-player;
the RebuildScopedLights callback is deleted. Live-verified with the probe:
full-circle turn, flood churning 8..41, the floor set held the same 8
identities on every post-spawn frame. The purple wedge SHAPE stays - it
is cdb-proven retail-faithful.
Residual deviation (AP-85 rewritten): single 128 pool vs retail's
7-dynamic/40-static degrade-scaled dual pools - the Hub now shows
7 purples + viewer where retail's cdb showed 4 + viewer + fixture slots;
if the gate reads the wedge as too purple, the A7 dual-pool cap is the
faithful trim.

The [seam-*] probes stay until the visual gate passes, then strip.

cdb trace of LIVE retail (tools/cdb/issue176-floor-light.cdb, binary<->PDB MATCH) PROVED retail
applies ALL its dynamic lights — 4 intensity-100 magenta portal lights (d3dIdx 3-6, falloff 6) +
the viewer fill (d3dIdx 1, 2.25) — as D3D hardware lights to EVERY Facility Hub cell, every frame,
stable. So the faceted purple wedges on the floor are retail-FAITHFUL. acdream did a per-cell
SelectForObject sphere-overlap 8-cap for cells, so the portal set could differ/flip per cell.
- LightManager.SelectForCell (retail minimize_envcell_lighting 0x0054c170): ALL dynamic lights
applied unconditionally (shader range cutoff zeroes non-reaching = D3D hardware range), then
nearest static torches fill remaining slots. Wired into EnvCellRenderer.GetCellLightSet.
Objects keep SelectForObject (minimize_object_lighting). Pins:
SelectForCell_AppliesAllDynamicLights_EvenOutOfReach + _SameDynamicSet_ForCellsFarApart_NoFlap.
- Apparatus: [light-detail] gains owner/cell/dyn (pinned the culprit = 2 portal weenies
0x000F4247/48 in 0x8A020118/19, intensity=100 magenta); CellVertexNormals_SmoothOrFaceted_Dump
(corridor floor uses SMOOTH per-vertex dat normals, not flat); tools/cdb/issue176-floor-light.cdb.
#176 RESIDUAL is NOT this fix. It's a RUNTIME draw z-fight in the seam floor. Eliminated (evidence):
NOT lighting (per-light cap + this both no-change), NOT membership (render cell 0x8A020164 stable
100% of 188k frames / 526 angles, res=None), NOT dat geometry (coplanar sweep empty at z=-6 floor
incl. cell 0164). NEXT = RenderDoc pixel-history. Full handoff + DO-NOT-RETRY:

Port retail's per-frame light collection: the point-light pool is built from ONLY the
currently-visible cells' lights, matching CObjCell::add_*_to_global_lights
(0x0052b350/0x0052b390) walked over CEnvCell::visible_cell_table (0x0052d410) — not a
flat world-space set capped at 128-nearest-camera.
- LightSource.CellId (retail insert_light arg6 -> RenderLight +0x6c); tagged at both
registration sites from entity.ParentCellId (live weenie fixtures + dat EnvCell statics).
- LightManager.BuildPointLightSnapshot(camPos, visibleCells): a light joins the pool iff
CellId==0 (viewer/global) or its cell is in the flood. 128 cap kept as a now-non-biting
backstop (retail's is 40 static + 7 dynamic, 0x0081ec94/8).
- Threaded via RetailPViewDrawContext.RebuildScopedLights, invoked in DrawInside after the
flood resolves prepareCells and before the draws (renderers select from the same
in-place-rebuilt PointSnapshot; EnvCellRenderer clears its per-cell cache each pass).
- [indoor-light] probe (ACDREAM_PROBE_INDOOR_LIGHT=1) dumps the scoped-pool SET COMPOSITION.
Un-skips LightManagerTests.PointSnapshot_HubScaleLightCount_ObjectSelectionIsCameraInvariant.
CORRECTION: the handoff called the camera-cap the "confirmed" #176/#177 mechanism. The probe
PROVES scoping works (291 Hub fixtures -> pool of 1-9, ~285 through-floor lights dropped/frame,
CellIds match the flood), but the user's VISUAL GATE showed BOTH symptoms unchanged. So pool
composition is NOT the cause. #176 real cause = an over-bright purple point light
(intensity=100, color 0.784,0,0.784 -- from [light-detail]); #177 = a portal-visibility miss
(stairs not drawn looking back). Both stay OPEN. This change is retail-faithful and retires the
camera-eviction latent bug; kept as such, not as the symptom fix. Register AP-85 corrected;
ISSUES #176/#177 re-diagnosed; render digest banner updated.

ParticleRenderer.Draw is called up to ~11 times per frame (sky pre/post,
scene, per-visible-cell, dynamics, unattached passes). Each call
allocated a fresh List<ParticleDraw> (BuildDrawList) and a fresh
List<ParticleInstance> (the per-batch `run` list), and ParticleSystem.
EnumerateLive was a `yield return` iterator block - a heap-allocated
state machine allocated fresh on every Draw call regardless of particle
count.
Fix: reuse _drawListScratch/_runScratch fields (Clear() + refill) on
ParticleRenderer. Replace EnumerateLive's iterator with a struct
enumerable/enumerator pair (ParticleSystem.LiveParticleEnumerable): the
foreach fast path uses the struct enumerator directly (zero allocation),
while LINQ/test callers (.ToList(), .Single(), etc.) still work via the
explicit IEnumerable<T> interface implementation, which falls back to a
boxed iterator only when that surface is used - those call sites are
test-only, not the per-frame render path this task targets.
Verified safe: all 11 Draw() call sites in GameWindow.cs are plain
synchronous invocations from the single-threaded OnRender chain (no
Task.Run/Parallel dispatch), and each call fully drains its lists
before returning - no call ever overlaps another's use of the reused
buffers. Per-cell filtering semantics unchanged (same predicate, same
traversal order).

AnimationSequencer.Advance() allocated a fresh PartTransform[partCount]
every call (BuildBlendedFrame/BuildIdentityFrame), and GameWindow.
TickAnimations reassigned entity.MeshRefs to a fresh List<MeshRef>(partCount)
every tick for every animated entity - including idle NPCs on a breathe
cycle. Both fire every frame in steady state and both become garbage
immediately after being consumed.
Fix: cache a PartTransform[] sized once in the AnimationSequencer
constructor (_setup is readonly and never reassigned, so partCount is
fixed for the sequencer's lifetime) and overwrite it in place each
Advance() call. Cache a List<MeshRef> on the long-lived AnimatedEntity
record (one per animated entity, held in GameWindow._animatedEntities)
and Clear()+refill it each tick instead of allocating a new list.
Verified safe: TickAnimations runs single-threaded to completion before
any draw-side consumer reads MeshRefs (WbDrawDispatcher re-reads
entity.MeshRefs fresh every frame, keyed by entity.Id - it never caches
the list reference across frames). The only place that copies MeshRefs
across an animation boundary (RefreshPaperdollDoll) takes an explicit
`new List<MeshRef>(pe.MeshRefs)` value copy; MeshRef is a readonly
record struct so that copy is unaffected by later in-place mutation of
the source list. No test holds two Advance() results simultaneously.
