Seven new high-level methods on NmxClient (port of cs:303-466). Each takes a GalaxyTagMetadata + typed WriteValue (re-exported from mxaccess-codec), builds the inner NMX body, wraps in NmxTransferEnvelope, and dispatches via the existing transfer_data opnum. Methods landed - write (cs:303-324) - write2 (cs:326-349, with explicit FILETIME timestamp) - write_secured2 (cs:351-380, dual user tokens via secured_write::resolve_observed_user_token; single-user secured = same id) - advise_supervisory (cs:382-399, ItemControl envelope) - send_observed_pre_advise_metadata (cs:401-420, hardcoded target platform/engine = (1, 1) per the .NET reference) - register_reference (cs:422-441, accepts caller-built NmxReferenceRegistrationMessage) - un_advise (cs:443-466, deliberately uses NmxTransferMessageKind::Write per cs:457 — the .NET reference's divergence from AdviseSupervisory's ItemControl envelope, preserved verbatim per CLAUDE.md unknown-bytes rule) Internal encode_*_transfer_body helpers extracted as pub(crate) fn for testability — mirrors the .NET reference's `internal static` shape. NmxClientError gained two new variants: Codec(CodecError) for metadata->reference-handle and value-encode failures, and UnsupportedDataType for the kind-resolution path. Cargo.toml: added mxaccess-galaxy as a dep on mxaccess-nmx. design/followups.md: F13 moved to Resolved. Test count delta: 459 -> 468 (+9 in mxaccess-nmx; 8 -> 17). Tests cover each encode helper standalone (envelope-kind + length checks) plus real-socket round-trip tests for write / advise_supervisory / send_observed_pre_advise_metadata. All four DoD gates green. 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.
