28d2c6018e feat(A.5 T22.5): wire QualityPreset into renderer + streaming (commit 2/2)
GameWindow.OnLoad resolves QualitySettings.From(_persistedDisplay.Quality)
+ WithEnvOverrides() immediately after LoadAndApplyPersistedSettings, stores
result in _resolvedQuality field. All six quality dimensions applied:

- NearRadius / FarRadius: replace old T16 env-var-only block; preset drives
  the radii, legacy ACDREAM_STREAM_RADIUS override still honoured.
- MsaaSamples: WindowOptions.Samples reads from startup quality resolution
  in Run() (pre-window-create read from SettingsStore). MSAA cannot change
  at runtime; ReapplyQualityPreset logs a restart-required warning if the
  new preset would change it.
- AnisotropicLevel: TerrainAtlas.SetAnisotropic() called after Build() and
  again in ReapplyQualityPreset. Temporarily removes bindless residency
  before the GL TexParameter call, re-makes resident after.
- AlphaToCoverage: WbDrawDispatcher.AlphaToCoverage property gates the
  glEnable/glDisable(SampleAlphaToCoverage) pair around the opaque pass.
- MaxCompletionsPerFrame: set on StreamingController after construction
  and after each mid-session restart.

ReapplyQualityPreset(QualityPreset) method handles mid-session changes
(Settings panel Quality dropdown Save): rebuilds streamer + controller for
radius changes, toggles A2C and aniso immediately, logs MSAA restart caveat.
onSaveDisplay callback updated to call ReapplyQualityPreset when Quality
field changes.

TerrainModernRenderer.Atlas property added to expose the atlas for
mid-session aniso updates.

991 tests passing, 8 pre-existing failures unchanged.

c473feedb3 feat(A.5 T23): BUDGET_OVER flag in [WB-DIAG] / [TERRAIN-DIAG]
Per Phase A.5 spec §2 acceptance criterion 6: entity dispatcher median
≤ 2.0ms; terrain dispatcher median ≤ 1.0ms at standstill. When the
median exceeds the budget, prefix the DIAG line with " BUDGET_OVER" so
the regression is grep-friendly during perf testing.

26b2871b10 feat(A.5 T20): MSAA 4x + alpha-to-coverage on foliage
Per Phase A.5 spec §4.9.2: ClipMap foliage uses binary alpha-cutoff.
At N₂=12 horizon distance the pixel-stepped silhouettes are visible.
A2C with MSAA 4x produces smooth retail-faithful tree edges.

GL context now requests Samples=4. WbDrawDispatcher's opaque pass
toggles GL_SAMPLE_ALPHA_TO_COVERAGE on/off around the multi-draw
indirect call. mesh_modern.frag's opaque pass now discards only
truly-empty (α<0.05) so the GPU derives sample mask from coverage;
transparent pass boundary logic is unchanged.

MSAA audit: no custom FBOs found — all rendering uses default
framebuffer. Sky/particles/ImGui are all MSAA-compatible.

0afd741ea7 feat(A.5 T18): use cached WorldEntity AABB in dispatcher; populate at register
Per Phase A.5 spec §4.6 Change #2: WalkEntities's per-entity AABB
frustum cull was recomputing Position±5 per frame per entity. With
~10.7K entities (N1=4) at 240 FPS that is ~2.5M wasted Vector3
ops/sec.

Read the AABB from the WorldEntity cache (T8 schema) instead.
RefreshAabb runs lazily on AabbDirty=true. Populate at register time:

- LandblockLoader.BuildEntitiesFromInfo: RefreshAabb after each new
  WorldEntity construction (stabs + buildings). Refactored from
  inline object-initializer to named variable to enable the call.
- EntitySpawnAdapter.OnCreate: RefreshAabb after entity state init
  (position/rotation already set via the WorldEntity passed in).

Dynamic entities (NPCs, players) move every frame via direct
Position writes in GameWindow.cs. Migrated all three per-frame
write sites to SetPosition() (T8 mutator) so AabbDirty propagates:
  - line 5942: player entity render position update
  - line 6951: remote animated entity interpolated path
  - line 7279: remote animated entity landing/movement path

The lazy RefreshAabb in WalkEntities catches up on the next frame
after any SetPosition call — render thread only, no races.

Build green, 986 passed / 8 pre-existing failures unchanged.

003443cd1a feat(A.5 T17): WbDrawDispatcher Change #1 — animated-walk fix + WalkEntities helper
Per Phase A.5 spec §4.6 Change #1: when an LB is invisible AND
animatedEntityIds is non-empty, the inner loop walked every entity
in the LB just to find the few animated ones. At ~10.7K entities
(N1=4) that is wasted iteration cost per frame.

Extracted a pure-CPU internal static WalkEntities helper. When LB
is invisible: iterate animatedEntityIds directly and look each up
in a per-LB AnimatedById dictionary (typically <50 animated vs
~10K total). When LB is visible: walk all entities as before.

GpuWorldState.LandblockEntries now yields an AnimatedById map as a
5th tuple field alongside the AABB tuple. Dictionary is built on
each yield (cheap — ~132 entities/LB max). A caching layer is out
of A.5 scope.

WbDrawDispatcher.Draw signature updated to consume the 5-tuple.
GameWindow.cs call site passes _worldState.LandblockEntries which
now yields the 5-tuple — no change needed there.

8 new tests in WbDrawDispatcherBucketingTests cover T17 Change #1
(invisible LB / animated set / neverCull / null frustum) and
T18 Change #2 guard tests (cached AABB / dirty flag / animated bypass).

da56063be5 fix(N.5b): black terrain — switch to uvec2 handle + sampler constructor
Symptom: terrain renders pure black in modern path (legacy renderer
correct). Diagnostic at TerrainModernRenderer.Draw showed:
  glProgramUniformHandle(prog=4, loc=5, handle=0x100251xxx) → GL_INVALID_OPERATION (0x0502)
on both terrain and alpha sampler uniforms.

Root cause: the `uniform sampler2DArray` + glProgramUniformHandleARB
combination is rejected by the NVIDIA Windows driver in this configuration.
The handle is valid and resident; the uniform location is valid; the
program is valid; but the driver refuses to bind a 64-bit handle to a
sampler uniform via the program-uniform path.

Fix: switch to N.5's mesh_modern pattern — pass each 64-bit handle as a
`uniform uvec2` (low + high 32-bit halves) and construct the sampler at
the use site via the GLSL `sampler2DArray(handle)` constructor. This
form is what ARB_bindless_texture documents as universally supported and
is what N.5 already uses successfully.

Files:
- terrain_modern.frag: replace `uniform sampler2DArray uTerrain/uAlpha`
  with `uniform uvec2 uTerrainHandle/uAlphaHandle` + `#define`s
- TerrainModernRenderer.cs: cache uvec2 uniform locations; set via
  `glProgramUniform2(program, loc, low32, high32)` per frame
- BindlessSupport.cs: remove now-unused `SetSamplerHandleUniform`,
  leave a comment noting why the helper was retired
- GameWindow.cs: also strip the temporary [TERRAIN-DBG] cursor-wrap
  print added during the perf-baseline investigation

Build green; 114/114 tests in N.5+N.5b filter still pass; user-verified
terrain renders correctly in modern path post-fix. Captured fresh perf
baseline:
- Legacy:  cpu_us median  1.5  / p95  3.0  (1 chunk = 1 glDrawElements)
- Modern:  cpu_us median  6.4-7.0 / p95  9-14 (51 visible LBs, 1 MDI call)

Modern is ~4× slower on CPU at radius=5 because the chunked legacy path
already collapsed the scene to one draw call. The architectural wins
(zero glBindTexture/frame; constant-cost dispatch as A.5 raises radius)
will be documented in T10's perf baseline doc; the spec's
"≥10% lower CPU" acceptance criterion is invalid at radius=5 and needs
revision.

0a77bd1fd7 phase(N.5b) Task 6: TerrainModernRenderer
The new terrain dispatcher. Single global VBO/EBO with a slot
allocator (one slot per landblock, 384 verts × 40 bytes per slot).
Per-frame: build DEIC array from visible slots, upload, dispatch
via glMultiDrawElementsIndirect. Atlas textures bound via bindless
handles set per-frame as sampler uniforms.

Total ~6-8 GL calls per frame for terrain regardless of visible
landblock count (vs today's per-LB binds at radius=2 → ~25 calls,
radius=5 → ~121 calls).

API mirrors TerrainChunkRenderer so GameWindow integration in T8 is
a drop-in field+ctor swap.

dcae2b6b94 phase(N.5): retirement amendment — InstancedMeshRenderer + StaticMeshRenderer + WbFoundationFlag deleted
Final cross-cutting review of N.5 found that Task 15's deletion of
mesh_instanced.vert/.frag left InstancedMeshRenderer orphaned —
ACDREAM_USE_WB_FOUNDATION=0 silently rendered terrain+sky only with
no entities. The SHIP commit's "[x] ACDREAM_USE_WB_FOUNDATION=0 still
works" claim was inaccurate.

Resolution: formal retirement of the legacy renderer path within N.5
instead of deferring to N.6.

Deleted:
- src/AcDream.App/Rendering/InstancedMeshRenderer.cs
- src/AcDream.App/Rendering/StaticMeshRenderer.cs
- src/AcDream.App/Rendering/Wb/WbFoundationFlag.cs

GameWindow simplified — capability detection is unconditional, missing
bindless throws NotSupportedException with a clear message at startup.
WbDrawDispatcher + mesh_modern shader load are mandatory after init.
No escape hatch.

GpuWorldState simplified — WbFoundationFlag.IsEnabled guards on
AddLandblock/RemoveLandblock removed; adapter calls are unconditional
when the adapter is non-null.

PendingSpawnIntegrationTests updated — WbFoundationFlag.ForTestsOnly_ForceEnable
static ctor removed (flag is gone; adapter calls are unconditional).

The ApplyLoadedTerrain physics-data loop was also simplified: the
EnsureUploaded sub-loop that fed InstancedMeshRenderer is gone;
_pendingCellMeshes is now explicitly cleared to prevent unbounded
accumulation (the worker thread still populates it, but WB handles
EnvCell geometry through its own pipeline).

Spec §2 Decision 5 + §10 Out-of-Scope updated. Plan ship-amendment
section added. Roadmap updated (N.5 ships with retirement; N.6 scope
narrowed to perf-only). CLAUDE.md "WB integration cribs" updated.
Perf baseline doc updated. WbDrawDispatcher class summary docstring
corrected to describe the as-shipped SSBO + multi-draw-indirect path.
ISSUES.md #51 updated (terrain not in N.5 scope; deferred to N.7).

Bindless support is now a hard requirement. Modern desktop GPUs
universally expose GL_ARB_bindless_texture + GL_ARB_shader_draw_parameters;
if a user hits the NotSupportedException, that's a real bug report
worth investigating, not a silent fallback.

Build: 0 errors, 0 warnings. Tests: 71/71 (Wb+MatrixComposition+TextureCacheBindless filter).

d114dca1e8 phase(N.5) Task 12: CPU stopwatch + GL_TIME_ELAPSED queries in [WB-DIAG]
Adds median + 95th-percentile CPU + GPU dispatch time to the existing
5-second [WB-DIAG] rollup. CPU via Stopwatch (always running, cheap;
only logged under ACDREAM_WB_DIAG=1). GPU via two GL_TIME_ELAPSED
queries (opaque + transparent) wrapping each glMultiDrawElementsIndirect,
polled non-blocking via QueryResultAvailable on the next frame.

Sample window is 256 frames per signal; median + p95 reported.
Numbers populate the SHIP commit's perf table at Task 19.

Silk.NET naming note: GL_TIME_ELAPSED queries use QueryTarget.TimeElapsed
(confirmed present in Silk.NET.OpenGL 2.23.0 DLL). The 64-bit result is
read via GetQueryObject(..., out ulong) which dispatches to
glGetQueryObjectui64v; the int overload (glGetQueryObjectiv) is used for
the ResultAvailable poll, matching WorldBuilder's VisibilityManager pattern.

cfe1ca3151 phase(N.5) Task 11: translucency partition contract test
Locks in Decision 2 (Opaque + ClipMap → opaque indirect; AlphaBlend +
Additive + InvAlpha → transparent indirect). Catches future refactors
that drift the partition — silent visual regression otherwise (groups
rendered in the wrong pass with the wrong blend state).

Adds public static IsOpaquePublic shim on WbDrawDispatcher; the
underlying IsOpaque stays private.

f533414edf phase(N.5) Task 10: glMultiDrawElementsIndirect dispatch — visual verified
Replaces WbDrawDispatcher's per-group glDrawElementsInstancedBaseVertexBaseInstance
loop with two glMultiDrawElementsIndirect calls (opaque + transparent).
Per-frame uploads three SSBOs:
- _instanceSsbo @ binding=0 (mat4 per instance, indexed by gl_BaseInstanceARB + gl_InstanceID)
- _batchSsbo @ binding=1 (BatchData per group, indexed by gl_DrawIDARB)
- _indirectBuffer (DrawElementsIndirectCommand[] — opaque first, transparent second)

GameWindow swaps the shader load to mesh_modern when _bindlessSupport
is non-null. Capability detection + shader load now run in the right
order (capability before TextureCache + before Shader).

Deletes the obsolete DrawGroup stub, EnsureInstanceAttribs, _instanceBuffer,
_patchedVaos. ClassifyBatches + ResolveTexture already migrated in
Task 8 to use ulong bindless handles.

BuildIndirectArrays (Task 9) wired in: _opaqueDraws + _translucentDraws
are flattened into IndirectGroupInput[], laid out via the helper into
contiguous indirect commands + parallel BatchData[]. opaqueByteOffset=0,
transparentByteOffset = opaqueCount × DrawCommandStride.

Visual verification (USER GATE) PASS: Holtburg courtyard renders
identical to N.4 — terrain, scenery, characters, NPCs all visible
without artifacts. [N.5] modern path capabilities present + mesh_modern
shader loaded log lines confirm the boot path. [WB-DIAG] hot-path
counters show healthy entity/draw activity.

b163c53622 phase(N.5) Task 9 fixup: layout assertion + DrawCommandStride const
Code quality review caught:
- sizeofDEIC was a local; promoted to public const DrawCommandStride
  so tests can reference it symbolically.
- BatchDataPublic layout invariant (size + field offsets) wasn't
  asserted in tests. Added BatchDataPublic_LayoutMatchesPrivateBatchData
  + DrawCommandStride_MatchesStructSize tests to gate Task 10's
  MemoryMarshal.Cast<BatchData, BatchDataPublic> safety.
- Plan doc updated: BatchDataPublic spec was Pack=4 (wrong — must
  match private BatchData's Pack=8 for the cast to work). Implementation
  was already correct; plan now matches.

9a7a250b62 phase(N.5) Task 9: BuildIndirectArrays — CPU layout for indirect dispatch
Pure CPU helper that lays out a group list into a contiguous indirect
buffer (DrawElementsIndirectCommand[]) and parallel BatchData[] —
opaque section first, transparent section second. Returns counts +
byte offset for the transparent section.

Tests cover: spec §5 walk-through layout; empty group list edge case;
ClipMap classification (treated as opaque, not transparent).

Static + public so tests can exercise without a GL context. Task 10
wires it into the rewritten Draw() method.

424d7b9015 phase(N.5) Task 8: InstanceGroup + GroupKey carry bindless handle + layer
Replaces uint TextureHandle (32-bit GL name) with ulong
BindlessTextureHandle (64-bit) in InstanceGroup + GroupKey + ResolveTexture
return type. Adds TextureLayer (always 0 for per-instance composites,
becomes meaningful when WB atlas is adopted in N.6).

ClassifyBatches now calls TextureCache.GetOrUpload*Bindless variants —
these return Texture2DArray-backed bindless handles (Task 3 work).

DrawGroup body throws NotImplementedException — Task 10 rewrites the
whole Draw() method to use glMultiDrawElementsIndirect, which makes
DrawGroup obsolete. CPU-only tests don't invoke DrawGroup so the build
+ test gates stay green; visual launch fails until Task 10 (intentional).

1b6995d2df phase(N.5) Task 7 fixup: BatchData Pack=8 for ulong alignment
Code quality review caught that BatchData uses Pack=4 but contains a
ulong field. With the current field order (TextureHandle first), offset
0 is always 8-byte aligned so std430 works. But adding a 4-byte field
before TextureHandle without bumping Pack would silently misalign the
GPU struct. Pack=8 makes the alignment requirement explicit and adds
a comment documenting expected std430 offsets.

No runtime change — current offsets (0/8/12) are identical under both
Pack values for this field order.

86c471d2d1 phase(N.5) Task 7: dispatcher SSBO + indirect buffer infrastructure
Adds DrawElementsIndirectCommand struct (20-byte layout for
glMultiDrawElementsIndirect). Replaces _instanceVbo field on
WbDrawDispatcher with three buffers: _instanceSsbo (mat4[]),
_batchSsbo (BatchData[]), _indirectBuffer (DEIC[]). Adds BindlessSupport
constructor parameter — non-null required since the dispatcher is only
constructed when WB foundation is on (which implies bindless is present
per Task 6 capability detection).

Existing Draw() method substitutes _instanceVbo -> _instanceSsbo for
compile. Behavior is temporarily wrong (SSBO bound as ArrayBuffer for
per-vertex attribs); Tasks 9-10 fully rewrite the draw loop and the
per-frame uploads to use BindBufferBase + glMultiDrawElementsIndirect.

GameWindow construction site updated to add _bindlessSupport guard and
pass it as the new last argument to the constructor. Dispatcher is only
constructed when bindless is guaranteed present.

12170f9d78 phase(N.5) Task 6 fixup: log symmetry + Silk extension shortcut
Code quality review caught:
- Silent failure when ARB_bindless_texture absent — the && short-circuit
  meant the most common fallback case (no bindless on the GPU) had no
  log, while ARB_shader_draw_parameters absent did log. Restructured to
  three nested ifs so each failure path logs symmetrically.
- Redundant `bindless is not null` guard removed (TryCreate's non-null
  guarantee covers it; the nested-if structure makes this implicit).
- HasShaderDrawParameters in BindlessSupport.cs replaced its manual
  GL_NUM_EXTENSIONS scan with `gl.IsExtensionPresent(...)` — same
  pattern WB uses, less code.

- _gl field stored but never used (TreatWarningsAsErrors=true would

- GL constructor parameter became unused after dropping _gl

c44536451d phase(N.4): SHIP — flag default-on + finalize plan + roadmap
Phase N.4 (Rendering Pipeline Foundation) ships. WbFoundationFlag
flips to default-on (== "1" → != "0"). WB's ObjectMeshManager is
now acdream's production mesh pipeline; WbDrawDispatcher is the
production draw path. Legacy InstancedMeshRenderer is retained as
ACDREAM_USE_WB_FOUNDATION=0 escape hatch until N.6 retires it.

Visual verification at Holtburg passed:
- Scenery (trees / rocks / fences / buildings) renders correctly
- Characters connected with full close-detail geometry (Issue #47
  preserved — GfxObjDegradeResolver path intact)
- FPS substantially improved by grouped instanced draws + per-entity
  AABB cull + opaque front-to-back sort + palette-hash memoization

Three high-value WB API gotchas surfaced during Task 26 visual
verification and are now documented in CLAUDE.md "WB integration
cribs" + plan Adjustments 7-9 + memory project_phase_n4_state.md:

1. ObjectMeshManager.IncrementRefCount only bumps a counter — does
   NOT trigger mesh loading. Call PrepareMeshDataAsync explicitly.
2. ObjectRenderBatch.SurfaceId is unset — read batch.Key.SurfaceId.
3. Modern rendering (GL 4.3 + bindless = every modern GPU) packs
   every mesh into ONE global VAO/VBO/IBO. Use
   glDrawElementsInstancedBaseVertex(BaseInstance) with FirstIndex +
   BaseVertex from the batch, not naive DrawElementsInstanced.

Plan doc flipped to Final state. Roadmap N.4 → Live ✓; N.5 rebranded
from "Terrain rendering" to "Modern rendering path" (bindless +
multi-draw indirect on top of N.4's foundation; terrain rendering
moves to N.5b). CLAUDE.md "Currently in flight" pointer updated to
N.5. New memory file project_phase_n4_state.md preserves the three
WB gotchas for cross-session continuity.

n4-verify*.log added to .gitignore.

573526dae5 phase(N.4): WbDrawDispatcher perf pass — sort, cull, hash memoization
Four small wins on top of the grouped-instanced refactor.

1. Drop unused animState lookup. Was a side-effect-free
   _entitySpawnAdapter.GetState call per per-instance entity, made
   redundant by the Issue #47 fix that trusts MeshRefs.

2. Front-to-back sort opaque groups. Squared distance from camera to
   each group's first-instance translation; ascending sort. Lets the
   GPU's depth test reject fragments behind closer geometry — real
   win on dense scenes (Holtburg courtyard, Foundry interior).

3. Per-entity AABB frustum cull. 5m-radius AABB check per entity
   before walking parts. Skips work for distant entities even when
   their landblock is partially visible. Animated entities (other
   characters, NPCs, monsters) bypass — they always need per-frame
   work for animation regardless. Conservative radius covers typical
   entity bounds; large outliers stay landblock-culled.

4. Memoize palette hash per entity. TextureCache.HashPaletteOverride
   is now internal; new GetOrUploadWithPaletteOverride overload takes
   a precomputed hash. The dispatcher computes it ONCE per entity and
   reuses across every (part, batch) lookup, avoiding the per-batch
   FNV-1a fold over SubPalettes. Trees / scenery without palette
   overrides skip entirely (palHash stays 0).

Visual output unchanged; FPS up further, especially in dense scenes.

7b41efc281 phase(N.4): WbDrawDispatcher — FirstIndex/BaseVertex + Issue #47 + grouped instanced draws
Three bugs surfaced and resolved during Task 26 visual verification.

1. **No-scenery + exploded characters**: WB's modern rendering path
   (GL 4.3 + bindless) packs every mesh into a single global VAO/VBO/IBO
   (GlobalMeshBuffer). Each batch references its slice via FirstIndex
   (offset into IBO) + BaseVertex (offset into VBO). The dispatcher's
   DrawElementsInstanced(indices=0) read offset 0 of the global IBO
   for every entity — drawing the same first triangle from every
   entity position. Switched to glDrawElementsInstancedBaseVertex(
   BaseInstance) with the batch's offsets. Scenery + connected
   characters now render correctly.

2. **Issue #47 character regression**: Adjustment 6 stored
   AnimPartChanges on WorldEntity.PartOverrides using the raw
   server-sent NewModelId (no degrade resolver applied). The
   dispatcher's animState.ResolvePartGfxObj override path then
   clobbered MeshRefs (which GameWindow's spawn code correctly
   resolves to close-detail meshes via GfxObjDegradeResolver).
   Result: humanoids drew low-detail (~14 verts/17 polys) base
   meshes instead of close-detail (~32 verts/60 polys), losing
   bicep / shoulder / back geometry. Fix: trust MeshRefs as the
   source of truth and don't re-apply animState overrides at draw
   time. AnimatedEntityState's overrides only matter for hot-swap
   appearance updates (0xF625) which today rebuild MeshRefs anyway.

3. **Performance — sub-100 FPS on Holtburg**: per-entity
   single-instance draws meant ~16K glDraw calls/frame plus a
   64-byte glBufferSubData per call. Refactored to grouped
   instanced rendering: bucket all (entity, batch) pairs by
   GroupKey(Ibo, FirstIndex, BaseVertex, IndexCount, TextureHandle,
   Translucency); upload all matrices in ONE BufferData call;
   one glDrawElementsInstancedBaseVertexBaseInstance per group
   with BaseInstance pointing at the group's slice in the shared
   instance VBO. Down from ~16K to a few hundred draws/frame
   (~30× fewer). Bind VAO once per frame (modern WB shares one
   global VAO). Removed redundant per-draw VertexAttribPointer
   (VAO captures that state).

Result: Holtburg renders correctly with characters showing full
detail; FPS climbed substantially. Two more bugs (mesh loading
+ batch.Key.SurfaceId) were fixed in the prior commit (943652d).

943652dc97 phase(N.4) Tasks 22+23 fixup: trigger WB mesh loads + correct SurfaceId source
Task 26 visual verification surfaced three bugs in the dispatcher.
Two are fixed here; the third is documented as a remaining issue.

1. WB's IncrementRefCount only bumps a usage counter — it does NOT
   trigger mesh loading. Fixed in WbMeshAdapter.IncrementRefCount:
   call PrepareMeshDataAsync(id, isSetup: false) on first registration.
   Result auto-enqueues to _stagedMeshData (line 510 of WB's
   ObjectMeshManager) which Tick() drains onto the GPU.

2. EntitySpawnAdapter never registered per-instance entity meshes
   with WB. LandblockSpawnAdapter only registers atlas-tier
   (ServerGuid == 0); per-instance entities fell through. Fixed by
   adding optional IWbMeshAdapter constructor param + tracking unique
   GfxObj ids per server-guid for IncrementRefCount on OnCreate /
   DecrementRefCount on OnRemove.

3. WbDrawDispatcher.ResolveTexture used batch.SurfaceId which WB
   never populates (line 1746 of ObjectMeshManager only sets
   batch.Key — the TextureKey struct that has SurfaceId). Switched
   to batch.Key.SurfaceId.

Plus diagnostic counters (ACDREAM_WB_DIAG=1) for entity-seen / drawn
/ mesh-missing / draws-issued counts.

Status: with these fixes the dispatcher now issues real draw calls
(~16K/frame, validated via diagnostic). However visual verification
shows characters appear "exploded" (parts spaced too far apart) and
scenery (trees/rocks/fences/buildings) does not appear. Root cause
analysis pending — Adjustment 7 in the plan documents the deferred
work. Flag stays default-off; legacy renderer remains the
production path.

01cff4144f phase(N.4) Tasks 22+23: WbDrawDispatcher + surface metadata side-table
WbDrawDispatcher draws all entities through WB's ObjectRenderData
(VAO/VBO per GfxObj, per-batch IBO) using acdream's TextureCache for
texture resolution. Two-pass rendering (opaque+ClipMap, then
translucent) matching the existing InstancedMeshRenderer pattern.
Per-entity single-instance drawing for N.4 simplicity — true
instancing grouping deferred to N.6.

Atlas-tier entities: mesh from WB, texture from TextureCache via
batch SurfaceId. Per-instance-tier entities: AnimatedEntityState
drives part overrides + hidden-parts, palette/surface overrides
resolve through TextureCache's composite-key caches.

Side-table population (Task 23 folded in): WbMeshAdapter now takes
DatCollection and populates AcSurfaceMetadataTable on first
IncrementRefCount per GfxObj. The side-table provides TranslucencyKind
(critical for ClipMap alpha-test on vegetation) plus Luminosity,
Diffuse, SurfOpacity, NeedsUvRepeat, DisableFog for sky-pass and
lighting.

GameWindow wiring: when WbFoundationFlag is enabled, WbDrawDispatcher
draws everything and InstancedMeshRenderer is skipped. Flag-off path
is unchanged.

Matrix composition: restPose * animOverride * entityWorld, matching
the spec. Three MatrixCompositionTests verify the contract.

5b4fd4b61d phase(N.4) Adjustment 6: add PartOverrides + HiddenPartsMask to WorldEntity
Resolves Adjustment 4 (Option A): WorldEntity now carries the server-
sent AnimPartChange data as PartOverrides and a HiddenPartsMask bitmask.
EntitySpawnAdapter.OnCreate populates AnimatedEntityState from these
fields at spawn time. GameWindow's CreateObject handler converts the
network-layer AnimPartChange records into lightweight PartOverride
structs.

This unblocks Task 22: the WbDrawDispatcher can now resolve per-part
GfxObj overrides and hidden-part suppression from entity state.

c02c307bee phase(N.4) Task 17: EntitySpawnAdapter for server-spawned per-instance content
Routes server-spawned (CreateObject) entities through the per-instance
rendering path. Filter: ServerGuid != 0. Atlas-tier entities (procedural,
ServerGuid == 0) flow through LandblockSpawnAdapter (Task 11) instead.

For entities with PaletteOverride set, walks each MeshRef.SurfaceOverrides
map and calls TextureCache.GetOrUploadWithPaletteOverride to pre-warm the
palette-composed GL texture before the first draw. Surfaces not in the
SurfaceOverrides map (i.e. whose ids are only known after opening the GfxObj
dat) are decoded lazily by the draw dispatcher on first use, consistent with
StaticMeshRenderer.

Builds AnimatedEntityState per server-guid via injected sequencer factory
(Func<WorldEntity, AnimationSequencer>). The factory decouples the adapter
from DatCollection so tests pass a stub lambda without a GL context.

OnRemove releases per-entity state. Unknown guids no-op.

Introduces ITextureCachePerInstance: thin seam interface over the palette
decode path so EntitySpawnAdapter tests can use a CapturingTextureCache
mock without constructing a GL context. TextureCache implements it.

Adjustment 4 documented in source comments: WorldEntity does not currently
expose HiddenPartsMask or AnimPartChanges (they are consumed upstream in the
network layer before the WorldEntity is built). HideParts / SetPartOverride
calls are placeholder TODO'd for when those fields are promoted.

Wired into GpuWorldState.AppendLiveEntity (OnCreate) and
RemoveEntityByServerGuid (OnRemove). Constructed in GameWindow under the
ACDREAM_USE_WB_FOUNDATION flag alongside LandblockSpawnAdapter. Sequencer
factory captures _dats + _animLoader at construction time; falls back to an
empty Setup + MotionTable via NullAnimLoader when dats are unavailable.

10 new tests: server-spawn routing, atlas-tier skip, palette decode pre-warm
(with and without surface overrides), OnRemove lifecycle, unknown-guid noop,
multi-entity isolation. All pass; 8 pre-existing failures unchanged.

ce72c574e9 phase(N.4) Tasks 16+18+19: AnimatedEntityState + AnimPartChange + HiddenParts
Per-entity render state for the per-instance rendering tier
(server-spawned characters / creatures / equipped items). Holds:
- partGfxObjOverrides: Dictionary<int, ulong> — AnimPartChange swaps
  (e.g. wielding a weapon replaces a hand-part's GfxObj).
- hiddenMask: ulong — HiddenParts bitmask. Bit i set hides part i.
- AnimationSequencer reference — N.4 doesn't touch the sequencer;
  this just exposes it for the draw dispatcher.

Public API: HideParts / IsPartHidden / SetPartOverride /
TryGetPartOverride / ResolvePartGfxObj. Bounds-checked
(partIdx < 0 or >= 64 → IsPartHidden returns false).

Twelve tests covering the type, the AnimPartChange resolution helper,
and the HiddenParts bitmask edge cases (theories for 0b0/0b1/MSB/all-ones,
plus negative-index + out-of-range guards).

Consumed by Task 17's EntitySpawnAdapter (creates one per CreateObject)
and Task 22's WbDrawDispatcher (reads via per-part draw loop).

bf53cb4fce phase(N.4): WbMeshAdapter.Tick — drain WB pipeline queues per frame
Without this, ObjectMeshManager.StagedMeshData and
OpenGLGraphicsDevice._glThreadQueue grow unbounded as background
workers prep mesh data + queue GL actions. Visual stress test of
flag-on at radius 7 showed real FPS drop and rising frame latency
from this leak.

Tick() drains both queues:
1. _graphicsDevice.ProcessGLQueue() applies pending GL state.
2. Loop _meshManager.StagedMeshData.TryDequeue -> UploadMeshData
   to materialize VAO/VBO/IBO for each prepared mesh.

Wired into GameWindow's render loop before draw work begins.
No-op when adapter is uninitialized or disposed.

Pattern matches WB's reference ObjectRenderManagerBase.ProcessUploads
without the prioritization heuristics (we're not yet drawing the
results — Task 22's WbDrawDispatcher will add prioritization when
visual budget matters).

f4f0101d2c phase(N.4) Task 14: pending-spawn list integration test
Verifies Task 12's GpuWorldState wiring preserves the pending-spawn
list mechanism:

1. Live entity parked before its landblock loads — pending count = 1,
   adapter not called yet.
2. Landblock arrives with its own atlas-tier entity AND drains the
   pending live entity. Adapter sees ONLY the atlas-tier GfxObj
   (server-spawned drained entity is filtered by ServerGuid != 0).
3. Live entity arriving AFTER landblock load goes straight to flat
   view; adapter is not re-invoked.
4. Landblock unload decrements match load increments.

Three integration tests confirm the existing pending-spawn drain
semantics work correctly with the new adapter, and per-instance-tier
entities (server-spawned) never leak into WB's atlas pipeline.

To exercise the adapter code path (which GpuWorldState gates on
WbFoundationFlag.IsEnabled) without requiring the env var set before
process startup, WbFoundationFlag gains an internal
ForTestsOnly_ForceEnable() method and AcDream.App exposes internals
to AcDream.Core.Tests via InternalsVisibleTo.

669768d9da phase(N.4) Task 11: LandblockSpawnAdapter (atlas-tier ref-count bridge)
Bridges LoadedLandblock load/unload events to IWbMeshAdapter ref counts.
Tier-aware by design: walks WorldEntity collection filtered by
ServerGuid == 0 (procedural / atlas-tier only). Server-spawned entities
are skipped — those will go through EntitySpawnAdapter (Task 17).

Per-landblock id-set snapshot ensures unload pairs 1:1 with load even
when underlying data is released. Duplicate-load idempotency for
defensive resilience to streaming-controller bugs.

Six tests: registers per unique id; dedups across entities; skips
server-spawned; unload matches load; unknown landblock no-ops;
duplicate load no-ops.

Wiring into GpuWorldState lands in Task 12.

4ad7a985cf phase(N.4) Task 9: real WB pipeline bring-up + InstancedMeshRenderer routing
WbMeshAdapter now actually constructs the WB pipeline:
- OpenGLGraphicsDevice(gl, logger, DebugRenderSettings)
- DefaultDatReaderWriter(datDir) — opens its own file handles for now
  (memory cost ~50-100MB of duplicate index caches, acceptable for
  foundation work per plan Adjustment 1)
- ObjectMeshManager(graphicsDevice, dats, NullLogger)

InstancedMeshRenderer.EnsureUploaded routes through the adapter when
ACDREAM_USE_WB_FOUNDATION=1 is set; uses a WbManagedSentinel entry
in the local cache to mark "this GfxObj lives in WB now". CollectGroups
skips sentinel entries; both Draw passes skip them; Dispose skips them
(no GL resources to free — ObjectMeshManager owns those). Task 22's
WbDrawDispatcher will eventually draw WB-managed objects. With flag
off, behavior is byte-identical to before.

WbMeshAdapter constructor signature changed from (GL, DatCollection,
Logger) to (GL, string datDir, Logger). Updated tests to use
CreateUninitialized() for behavior tests and single null-GL guard test
for constructor validation. GameWindow updated to pass _datDir and to
wire _wbMeshAdapter into InstancedMeshRenderer.

AcDream.App.csproj gets direct ProjectReferences to WorldBuilder.Shared
and Chorizite.OpenGLSDLBackend — project refs are not transitive in
.NET, so AcDream.App must list them explicitly even though AcDream.Core
already references them.

1030c69b3c phase(N.4): WbMeshAdapter stub + IWbMeshAdapter interface
Stub adapter that validates constructor args and exposes the public
shape (IncrementRefCount / DecrementRefCount / GetRenderData / Dispose).
Real ObjectMeshManager init is deferred to Task 9 — for now methods
no-op so call sites can wire the adapter without behavioral effect.

IWbMeshAdapter interface enables mocking in subsequent tasks
(LandblockSpawnAdapter tests in Task 11 need it).

DisableFog keyed by (gfxObjId, surfaceIdx). Populated at extraction time,
queried by the draw dispatcher. ConcurrentDictionary because mesh
extraction happens on background workers.
