Five small post-cleanup items from T7 code review:
I1: Removed dead `datDir` parameter from WbMeshAdapter ctor (parameter
was unused after _wbDats removal; ArgumentNullException.ThrowIfNull
was misleading). Updated call sites in GameWindow.cs and
WbMeshAdapterTests.cs.
I2: Updated stale GameWindow.cs comment that still described
WbMeshAdapter as opening its own dat handles. Now reflects Phase O
state: shared DatCollection via DatCollectionAdapter.
I3: Documented thread-safety contract on RenderStateCache (render-thread
only — required for the mutable-static GL sentinel pattern).
M1: Added comment on IDatReaderWriter's write-path methods noting they
are preserved for verbatim compatibility but unused in acdream.
M3: Added comment on Chorizite.Core PackageReference in Core.csproj
explaining the previously-transitive dependency.
Also excluded SplitFormulaDivergenceTest.cs from the test build via
<Compile Remove>: this N.5b one-time data-collection test referenced
WorldBuilder.Shared types directly; after Phase O-T7 dropped that
project reference it no longer compiles. The sweep data it produced
already informed the N.5b Path-C decision and the file is retained
in the tree for historical reference.
Build green; tests green (1146 + 8 pre-existing failures baseline
maintained).

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.

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).

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.

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).
