Erik 05749f52e0 test: port ACME ClientReference + conformance tests 
Ports the decompiled AC client ground-truth oracle and exhaustive
conformance test suite from WorldBuilder-ACME-Edition into acdream's
test project.

ClientReference.cs: faithful C# port of CLandBlockStruct.cpp with
IsSWtoNECut, GetPalCode, GetVertexHeight, GetVertexPosition.

ClientConformanceTests.cs verifies acdream's implementations match:
- SplitDirection: 9 spot-checks + 25,600-cell full sweep (0 mismatches)
- PalCode: 5 spot-checks + 256 exhaustive roads + 1M exhaustive types
- Height sampling: flat terrain exact match, vertex corners match,
  interpolated points in-range
- TerrainSurface.SampleZ agrees with TerrainBlending split direction
- Constants match (CellSize=24, CellsPerBlock=8, BlockLength=192)

27 new tests. 310 total (201 core + 109 net), all green.

Experimental modern open-source Asheron's Call client in C# / .NET 10.

Status: pre-alpha, not playable. Phase 0 only — dat file asset inventory.

Stack: .NET 10, Chorizite.DatReaderWriter for dat parsing. Silk.NET + Avalonia planned for rendering/UI (not yet wired up).

Requires: A retail Asheron's Call install (Turbine/Microsoft property — supply your own). Set ACDREAM_DAT_DIR environment variable to the directory containing client_portal.dat, client_cell_1.dat, client_highres.dat, and client_local_English.dat, or pass it as the first CLI argument.

Layout

  • src/AcDream.Cli/ — console app that dumps asset counts from a dat directory
  • references/ — local read-only reference material (ACE, ACViewer, WorldBuilder, DatReaderWriter, holtburger, retail AC install). Gitignored.

Run

dotnet run --project src/AcDream.Cli -- "C:\path\to\Asheron's Call"

Or set ACDREAM_DAT_DIR and run without args.
