Mirrors `AsbContracts.cs:109-114` — same payload shape as AuthenticateMe (Data + InitializationVector under ConsumerAuthenticationData) but under the `<DisconnectRequest>` wrapper. Sent one-way + signed (regular HMAC, no force) per `AsbContracts.cs:22` (`IsOneWay = true`). API additions: * `build_disconnect_request_body(data, iv)` — NBFX token stream for the DisconnectRequest body. * `AsbClient::disconnect()` — builds a fresh encrypted authentication-data blob via F23's `create_authentication_data()` (encrypts `local_pub || remote_pub` under the derived AES key with a fresh IV), wraps it in a DisconnectRequest, sends one-way signed. 2 new tests: * `disconnect_request_carries_data_and_iv_under_correct_wrapper` — outer element name + Data/IV byte-payload order. * `disconnect_writes_signed_one_way_envelope` — end-to-end via `tokio::io::duplex` peer; verifies the SizedEnvelope payload contains the `:disconnectIn` action string. With Disconnect landed, AsbClient now covers the full session lifecycle: send_preamble → connect → register_items / read / keep_alive / unregister_items → disconnect → send_end → stream shutdown 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.
