Lands the codec-only prerequisites for M2 wave 3 (callback exporter). The TCP server itself (port of ManagedCallbackExporter.cs's TcpListener + accept loop) follows next iteration in the mxaccess-callback crate. New modules - nmx_metadata.rs (9 tests) — port of NmxProcedureMetadata.cs. INmxService2 + INmxSvcCallback IIDs, NdrProcedureDescriptor with per-opnum metadata for the 9 INmxService2 procedures (opnums 3..11) and 2 INmxSvcCallback procedures (opnums 3, 4). - nmx_callback_messages.rs (8 tests) — port of NmxSvcCallbackMessages.cs. parse_callback_request decodes OrpcThis + i32 size + i32 max_count + body bytes; encode_callback_response produces the 12-byte OrpcThat + HRESULT response. objref.rs additions - ComObjRefBuilder::create_standard_objref (8 tests) — port of the second class in ManagedCallbackExporter.cs:337-393. Pure-Rust OBJREF emitter that builds 68-byte header + dual-string array. Note this is *not* the Win32 CoMarshalInterface-based ComObjRefProvider.cs (still open as F6); it's the higher-level emitter the callback exporter uses to build OBJREF bytes from primitives. - CALLBACK_OBJREF_AUTH_SERVICES const exposes the 7-entry auth-service tower-id table (NTLM SSP through Kerberos extension) the .NET reference advertises in every callback OBJREF. Test count delta: 319 -> 344 (+25; mxaccess-rpc 102 -> 127, codec unchanged at 215, parity unchanged at 2). All four DoD gates green. Open followups touched: none new; F6 advances toward resolution but the windows-rs Win32 wrapper part stays open. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
mxaccess (Rust port)
Native Rust replacement for AVEVA / Wonderware MXAccess. See ../design/ for
the architectural specification, ../src/ for the .NET reference (the
executable spec), and ../CLAUDE.md for project-wide rules.
Status
M0 — Workspace skeleton. Stub types compile; nothing is implemented yet.
See ../design/60-roadmap.md for the M0–M6 milestone plan.
