[M2] mxaccess-callback: tokio TCP exporter (wave 3 main)
Lands the M2 wave 3 main course — the INmxSvcCallback callback exporter.
Pure-tokio TCP server that mirrors src/MxNativeClient/ManagedCallbackExporter.cs
and lets a Rust client receive callbacks from NmxSvc.exe.
New
- exporter.rs (~700 LoC, 10 tests) — port of ManagedCallbackExporter.cs.
CallbackExporter::bind starts a TcpListener + accept loop; per-connection
serve task walks Bind / AlterContext / Request / Auth3 PDUs and dispatches
IRemUnknown (opnums 3/4/5) and INmxSvcCallback (opnums 3/4) requests.
Hand-rolled BindAck encoder mirroring cs:226-254 (single acceptance entry,
NDR20 transfer syntax).
- ExporterIdentities { oxid, oid, callback_ipid, rem_unknown_ipid } — exposes
both `random()` (production) and `fixed()` (tests). Mirrors the .NET
RandomUInt64 + Guid.NewGuid pattern at cs:14-20.
- CallbackEvent enum — typed diagnostic stream replacing .NET's
List<string> log (cs:12,33-42,315-321). Variants: ClientConnected,
AcceptError, Bind, Auth3Ignored, Request, RemQueryInterface,
CallbackInvoked, UnhandledRequest, ClientDisconnected, ProtocolError.
- IUNKNOWN_IID const re-exported alongside the other IIDs.
Tests cover real-socket round-trips: Bind+RemQueryInterface (with IUNKNOWN
returning S_OK), Bind+unknown opnum -> Fault, Bind+DataReceived ->
CallbackInvoked event + 12-byte success response, and graceful shutdown.
Test count delta: 344 -> 354 (+10).
Open followups touched: none new. F2 (verify_signature path) still
gated on a live status-frame fixture under tests/fixtures/m2-status-frame/.
F6 / F9 still need the windows-rs and DceRpcTcpClient ports respectively.

Initial project state: .NET reference, design, Rust port (M0+M1), evidence
rust / build / test / clippy / fmt (push) Has been cancelled
Layout:
- src/ .NET 10 x64 reference: MxNativeCodec, MxNativeClient,
MxAsbClient, probes, tests, harnesses. Executable spec.
- design/ Architectural plan for the Rust port (M0–M6), error
model, protocol invariants, risks (R1–R16), adversarial
review log (review.md).
- rust/ Rust workspace. M0 skeleton + M1 codec parity.
mxaccess-codec: 215 unit tests + 2 cross-implementation
parity tests (byte-identical against .NET reference).
Other crates are M0 stubs awaiting M2+.
- captures/ Frida + netsh + pcap evidence per CLAUDE.md
("captures are evidence, not throwaway logs").
- analysis/ Decompiled C# (frida/proxy/decompiled-*),
Ghidra exports for native DLLs (`exports/` only —
working state at `projects/` and AVEVA's input
binaries at `input/` are gitignored).
- docs/ Reverse-engineering reference docs.
- tools/ Setup-LiveProbeEnv.ps1 (Infisical credential fetcher),
Compute-Crc.ps1 (.NET parity helper).
- .github/workflows/ Rust CI: fmt + build + test + clippy on Windows.
- LICENSE MIT (Joseph Doherty, 2026).
Verified:
- cargo test --workspace → 217 passed (215 unit + 2 .NET parity), 0 failed
- cargo clippy --workspace -- -D warnings → clean
- cargo fmt --all -- --check → clean
- cargo publish --dry-run -p mxaccess-codec → packages cleanly
Excluded from history (see .gitignore):
- **/bin, **/obj, **/target — build artifacts
- analysis/ghidra/projects/ — Ghidra working state (regenerable)
- analysis/ghidra/input/ — AVEVA proprietary DLLs (vendor IP)
