Erik 11974c2099 feat(net): track + echo movement sequence counters 
Sprint 1a of the audit remediation plan.

Extracts the 4 movement sequence counters from inbound server messages
and echoes them in outbound MoveToState + AutonomousPosition instead
of hardcoded zeros:

- instanceSequence (slot 8 in CreateObject PhysicsData timestamps)
- teleportSequence (slot 4, also from PlayerTeleport 0xF751)
- serverControlSequence (slot 5)
- forcePositionSequence (slot 6, also from UpdatePosition 0xF748)

Source: holtburger player/types.rs:237-245, mutations.rs:182-706.
The server uses these to detect stale/reordered movement packets.
Previously all zeros → server couldn't distinguish epoch boundaries.

Changes:
- CreateObject.Parsed: +4 sequence fields extracted from timestamps
- UpdatePosition.Parsed: +3 sequence fields from trailing u16s
- WorldSession: tracks 4 counters, updates from CreateObject/
  UpdatePosition/PlayerTeleport for the player's own GUID
- GameWindow: passes tracked values to MoveToState.Build and
  AutonomousPosition.Build

acdream

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.
