Locks the four decisions from brainstorming: full scope (all 8 sketched
tasks in one Phase 2b), GL_TEXTURE_2D_ARRAY for terrain atlas with a
per-vertex flat uint layer attribute, raw cursor capture FlyCamera with
F toggle and Escape release, and WorldEvents.EntitySpawned with
replay-on-subscribe so plugin ordering doesn't matter.
Grows AcDream.Plugin.Abstractions by IGameState + IEvents +
WorldEntitySnapshot. Host-side WorldGameState + WorldEvents implementations
live in AcDream.App.Plugins. AppPluginHost constructor gains two
parameters. Program.cs wiring order keeps Phase 2a's Enable-before-Run,
relying on replay-on-subscribe to make subscription-before-world-load
produce the right observable behavior.
Task 1 expands Vertex struct and LandblockMesh signature — this affects
StaticMeshRenderer's vertex stride too, so Phase 2a's shader bindings
need a matching update.

Tasks 1-10 are fully specified TDD-bite-sized and cover Phase 2a:
scaffold + GfxObjMesh.Build + SurfaceDecoder + LandblockLoader +
SetupMesh.Flatten + WorldView + TextureCache + StaticMeshRenderer +
debug + visual verification. End state: Holtburg terrain with buildings
rendered and at least some textures resolved.
Tasks 11-18 are sketches for Phase 2b in a future session: terrain
atlas, 3x3 neighbor rendering, ICamera/FlyCamera/CameraController, and
the IGameState/IEvents plugin API growth. These will be re-planned
with fresh context once Phase 2a is known to work.

Verified the real GfxObj data shape against DatReaderWriter's generated
types and WorldBuilder's ObjectMeshManager. Three corrections:
- GfxObj.Surfaces is a list and Polygon.PosSurface indexes into it;
multiple surfaces per GfxObj are the norm. GfxObjMesh.Build now
returns IReadOnlyList<GfxObjSubMesh> — one sub-mesh per referenced
surface. StaticMeshRenderer draws entities by grouping entities by
GfxObj and then by sub-mesh within each GfxObj. Matches the approach
WorldBuilder takes.
- LandBlockInfo has both Objects (Stabs — small decorations, rocks,
trees) AND Buildings (BuildingInfo). LandblockLoader loads both
lists and maps them uniformly to WorldEntity since both types share
the Frame shape.
- Stab.Frame and BuildingInfo.Frame carry position+orientation only,
no scale component. WorldEntity.Scale dropped. WorldEntitySnapshot
loses its Scale field too. Phase 3+ can add it back if needed.
Closes the one open design question flagged in the original doc.

Locks the design decisions from brainstorming: full scope (geometry +
textures + 3x3 neighbor grid), dual cameras (orbit default + FlyCamera
toggled by F), minimal plugin API growth (IGameState.Entities snapshot
+ IEvents.EntitySpawned). BCnEncoder.Net handles DXT/BCn decoding,
matching WorldBuilder's approach.
Adds three new namespaces under AcDream.Core (World, Meshing, Textures)
and three new rendering components under AcDream.App (StaticMeshRenderer,
TextureCache, FlyCamera + ICamera). Entities are deduplicated by
GfxObj id at the GPU layer; textures dedup by Surface id. Plugins
get immutable snapshots, not live references.

Ten bite-sized tasks covering: solution reorg into four projects,
TDD-driven PluginManifest parsing + discovery + collectible-ALC
loader (with a real fixture DLL), LandblockMesh pure generator,
Silk.NET window smoke, dat-backed landblock mesh upload, height-
ramp shader + orbit camera, and finally the end-to-end smoke
plugin round-trip. Manual visual smoke only for the GL bits;
xUnit TDD for everything testable.

Captures the day-1 plugin + scripting contract for acdream:
C# plugins via collectible AssemblyLoadContext with a stable
IPluginHost API, Lua macros via a first-party Macros plugin that
embeds MoonSharp, and a four-stage packet pipeline for raw and
parsed traffic in both directions. Extends the phased MVP so
every core system is exposed through the plugin API in the same
commit that adds it.
