End of Phase O extraction. Final cleanup:
- Dropped <ProjectReference> entries to WorldBuilder.Shared and
Chorizite.OpenGLSDLBackend from both AcDream.App.csproj and
AcDream.Core.csproj.
- Added Chorizite.Core NuGet PackageReference to AcDream.Core.csproj
(needed by Core.Rendering.Wb.TextureHelpers for TextureFormat enum;
previously transitive through the WB project ref).
- Added BCnEncoder.Net.ImageSharp (1.1.2) + SixLabors.ImageSharp (3.1.12)
as direct PackageReferences to AcDream.App.csproj — previously transitive
via Chorizite.OpenGLSDLBackend project; used directly by ObjectMeshManager.
Item A (BaseObjectRenderManager static fields):
- Inlined CurrentAtlas/CurrentVAO/CurrentIBO into a new RenderStateCache.cs
static class (AcDream.App.Rendering.Wb namespace) — the 4 consumers
(ManagedGLIndexBuffer, ManagedGLTexture, ManagedGLTextureArray, ParticleBatcher)
all reference RenderStateCache.* instead of BaseObjectRenderManager.*.
- Dropped using Chorizite.OpenGLSDLBackend.Lib from all 4 consumers and from
WbDrawDispatcher (which had it only as a dead import).
Item B (ActiveParticleEmitter.ObjectLandblock):
- ObjectLandblock? erased to object?; WorldBuilder.Shared.Models.ObjectId? erased
to ulong? — both fields are stored but never read by any consumer in our codebase.
- Dropped both WB using directives from ActiveParticleEmitter.cs.
Item C (IDatReaderWriter / IDatDatabase):
- Verbatim copy of both interfaces into IDatReaderWriter.cs in
AcDream.App.Rendering.Wb namespace — DatCollectionAdapter and ObjectMeshManager
already live in that namespace, so no using changes needed.
- Dropped using WorldBuilder.Shared.Services from DatCollectionAdapter.cs and
ObjectMeshManager.cs.
Additional extractions required by the reference drop:
- GeometryUtils.cs: verbatim copy of WorldBuilder.Shared.Lib.GeometryUtils
(float-precision overloads only; Vector3d double-precision overloads omitted —
ObjectMeshManager uses only the float versions).
- Dropped using WorldBuilder.Shared.Lib from ObjectMeshManager.cs.
WbMeshAdapter.cs cleanup (spec O-D12):
- Deleted _wbDats (DefaultDatReaderWriter) field + ctor init + Dispose call.
- Deleted the [indoor-upload] NULL_RESULT diagnostic block (lines ~205-262) —
its Phase 2 cell-resolution investigation is complete; its _wbDats.ResolveId
dependency goes with this commit.
- Deleted _pendingEnvCellRequests field + isPendingEnvCell tracking in Tick().
- Simplified Tick() to a clean drain loop.
Deleted SplitFormulaDivergenceTest.cs — one-time N.5b data-collection sweep;
job done.
Verified acceptance criteria:
- Zero <ProjectReference> to WorldBuilder.* / Chorizite.OpenGLSDLBackend.* in any csproj.
- Zero 'using WorldBuilder.*' / 'using Chorizite.OpenGLSDLBackend.*' in src/.
- DefaultDatReaderWriter referenced in zero places in src/ (comments only).
Build green (0 warnings, 0 errors).
Tests: 1154 total (-1 from deleted SplitFormulaDivergenceTest), 1146 pass,
8 pre-existing failures (unchanged from baseline — physics/input tests
unrelated to this change).

Phase O Task 3 — verbatim-copy GL infra from Chorizite.OpenGLSDLBackend
into src/AcDream.App/Rendering/Wb/ (namespace AcDream.App.Rendering.Wb).
18 files extracted (all namespace-changed; no algorithm changes):
OpenGLGraphicsDevice, ManagedGLTexture, ManagedGLTextureArray,
ManagedGLVertexBuffer, ManagedGLIndexBuffer, ManagedGLVertexArray,
ManagedGLFrameBuffer, ManagedGLUniformBuffer, GLSLShader, GLHelpers,
GLStateScope, GpuMemoryTracker, SceneData, DebugRenderSettings,
TextureParameters, TextureFormatExtensions, BufferUsageExtensions,
EmbeddedResourceReader.
3 internals promoted to public (O-D9):
EmbeddedResourceReader, TextureFormatExtensions, BufferUsageExtensions.
SixLabors.ImageSharp not reachable: TextureHelpers was placed in
AcDream.Core (no GL/ImageSharp dep); only the GL types went to App.
TextureHelpers.GetCompressedLayerSize added to AcDream.Core.Rendering.Wb
(was in Chorizite.OpenGLSDLBackend.Lib.TextureHelpers; uses
Chorizite.Core.Render.Enums.TextureFormat which Core gets transitively
via the still-present WB project refs).
T3/T4 boundary interims:
- WbMeshAdapter._graphicsDevice stays Chorizite.OpenGLSDLBackend.OpenGLGraphicsDevice
(T4 will swap it when ObjectMeshManager is extracted).
- OpenGLGraphicsDevice.ParticleBatcher deferred to null! (T4 extracts
ParticleBatcher alongside ObjectMeshManager; can't pass `this` of our
new type to the WB-original ctor before T4).
- ManagedGLTextureArray uses our TextureHelpers via explicit alias.
- IUniformBuffer is in Chorizite.Core.dll under Chorizite.OpenGLSDLBackend
namespace (unusual packaging); resolved via type alias.
- AcDream.App.csproj gets explicit Chorizite.Core 0.0.18 PackageReference
(IUniformBuffer + other Chorizite.Core types now used directly in App).
Build green. Test baseline 1147+8 maintained (1902 passing, 8 pre-existing
MotionInterpreterTests failures unrelated to T3).
