Port retail's 25-second leave-visibility lifetime over canonical live records, retaining spatially resident and owned entities while using the conservative ACE visibility envelope for nonresident records. Route expiry through the normal generation-safe F747 teardown so animations, effects, physics, and render owners unwind symmetrically.
Replace the append-only modern mesh buffer with coalescing vertex/index ranges and upload each mesh's vertices once instead of once per material. Released zero-reference meshes can now reuse GPU ranges after portal and cache churn.
A connected five-region round trip returned animation ownership to baseline, recreated the starting region on revisit, and held normal FPS. Release build succeeds and all 5,927 tests pass with five intentional skips.

Phase O Task 4: extract the WB mesh pipeline (ObjectMeshManager + 7 support files)
from references/WorldBuilder into src/AcDream.App/Rendering/Wb/ and bridge dat I/O
through our DatCollection via a thin DatCollectionAdapter.
O-D7 adapter path taken: ObjectMeshManager has 26 _dats.X call sites (threshold 20),
so a DatCollectionAdapter : IDatReaderWriter is introduced rather than refactoring
ObjectMeshManager's internal dat access directly.
Files added (verbatim copies, namespace-only changes):
- ObjectMeshManager.cs — mesh pipeline hub; IDatReaderWriter field satisfied by adapter
- GlobalMeshBuffer.cs — single global VAO/VBO/IBO manager
- EdgeLineBuilder.cs — wireframe edge geometry from CellStruct polygons
- ModernRenderData.cs — ModernBatchData + LandblockMdiCommand structs
- TextureAtlasManager.cs — texture array grouping by (Width, Height, Format)
- ParticleBatcher.cs — GPU particle batching; T4 interim uses BaseObjectRenderManager
static fields from Chorizite.OpenGLSDLBackend.Lib (stays until T7)
- ParticleEmitterRenderer.cs — per-emitter particle lifecycle + rendering
- ActiveParticleEmitter.cs — wrapper holding renderer + part index + local offset
- DatCollectionAdapter.cs — NEW: bridges DatCollection → IDatReaderWriter; implements
ResolveId() via DatDatabase.TypeFromId + Tree.TryGetFile in HighRes→Portal→Language→Cell
order matching DefaultDatReaderWriter; DatDatabaseWrapper wraps DatDatabase as IDatDatabase
WbMeshAdapter.cs changes (T4 Step 6):
- _graphicsDevice switched from Chorizite.OpenGLSDLBackend.OpenGLGraphicsDevice to
extracted AcDream.App.Rendering.Wb.OpenGLGraphicsDevice
- ParticleBatcher = new ParticleBatcher(_graphicsDevice) restored (T3 had null! placeholder)
- ObjectMeshManager now constructed with new DatCollectionAdapter(dats) instead of _wbDats
- _wbDats field + its construction + disposal + [indoor-upload] NULL_RESULT diagnostic block
left intact — T7 cleanup removes these once WorldBuilder project ref is dropped
EmbeddedResourceReader.cs: replaced assembly manifest lookup (wrong prefix for our assembly)
with disk-based lookup mapping "Shaders.Particle.vert" → Rendering/Shaders/wb_particle.vert;
consistent with all other acdream shaders.
wb_particle.vert / wb_particle.frag: WB particle shaders copied verbatim with wb_ prefix
to distinguish from acdream's own particle.vert.
OpenGLGraphicsDevice.cs: ParticleBatcher property type updated to extracted ParticleBatcher;
setter changed from private to internal so WbMeshAdapter (same assembly) can assign post-ctor.
Build: green (0 errors, 0 warnings in AcDream.App).
Tests: 1147+8 baseline maintained (8 pre-existing failures unchanged).
