Erik 449c2caf8b fix(app): Phase A.1 — separate Visible from Resident in StreamingRegion 
Review follow-up from commit 11df793. Three fixes:

1. Visible semantics: StreamingRegion.Visible now strictly describes the
   current (2r+1)×(2r+1) window, not window + hysteresis retainees.
   Added a parallel Resident property exposing the actual loaded set
   (window + hysteresis buffer). This matters because StreamingController
   (next task) reads these to decide what to render vs what to unload;
   conflating them in one set would have forced awkward post-processing
   downstream.

2. Doc/code disagreement: updated the RecenterTo and RegionDiff doc
   comments from "radius + 1" to "radius + 2" to match the actual
   implementation (which is what the tests require). Also updated the
   plan doc so future readers don't hit the same contradiction.

3. Edge-clamping test coverage: added a single-axis edge test
   (cx=0, cy=50 → 15 entries) and an ID-encoding test (radius=0 at
   0x12,0x34 → 0x1234FFFE) so a swapped-shift bug in EncodeLandblockId
   or an asymmetric off-by-one would fail a test instead of passing
   silently.

9 tests green, full suite regressions-free.

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.
