First slice of F25. Provides the building blocks the per-operation
request/response codecs and the network loop will compose:
* `actions` module — IASBIDataV2 action strings (all 14 operations,
verbatim from `AsbContracts.cs:14-58`).
* `ConnectionValidator` — SOAP header struct mirroring
`AsbContracts.cs:65-117`. `from_signed(&SignedValidator)` converts
F23's MAC + IV to base64 for the wire, matching .NET's
`BinaryWriter`-via-`XmlSerializer` shape.
* `SoapEnvelope` + `encode_envelope` — assembles the NBFX token
stream: `s:Envelope` → `s:Header` → `a:Action s:mustUnderstand="1"`
→ optional `h:ConnectionValidator` → `s:Body` → caller-supplied
body tokens. Uses static-dictionary IDs for the SOAP/WS-Addressing
tokens via F22's `lookup_static`.
* `decode_envelope` — pulls action + validator + body tokens back
out of received bytes. Tolerant of header ordering.
* Mixed-endian GUID format/parse (`format_uuid` / `parse_uuid`) that
mirrors .NET's `Guid.ToString("D")` byte order so connection-id
round-trip matches the wire exactly.
9 new unit tests cover:
* Round-trip with and without validator.
* `from_signed` base64 encoding of MAC + IV.
* `format_uuid` produces the correct .NET-mixed-endian hex string.
* GUID round-trip through string formatter.
* Action string presence in the encoded byte stream.
* Decoder tolerance of envelopes without an Action header.
* Validator round-trip through full encode → decode.
* Lint-style guard that all 14 action constants are URIs ending `In`.
Stubbed for next F25 iteration: per-operation request/response
struct codecs (`ConnectRequest`, `RegisterItemsRequest`, etc.) +
`AsbClient` network loop.

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.
