Closes out the F25 operation matrix. AsbClient now wraps every
IASBIDataV2 operation:
Lifecycle: connect / disconnect / send_end / send_preamble / keep_alive
Items: register_items / unregister_items / read / write
Subscriptions:create_subscription / add_monitored_items / publish
/ delete_monitored_items / delete_subscription
Write cb: publish_write_complete
API additions:
* `build_publish_write_complete_request_body()` — empty wrapper
per `AsbContracts.cs:204-205`. No body fields beyond inherited
ConnectionValidator.
* `decode_publish_write_complete_response` — returns count of
`<ItemWriteComplete>` elements observed. Per-element decode
(Status + WriteHandle) deferred to a later iteration since
ItemWriteComplete is regular WCF DataContract rather than the
binary fast-path.
* `build_delete_monitored_items_request_body` — same MonitoredItem
shape as AddMonitoredItems but omits RequireId per `cs:268-277`.
* `decode_delete_monitored_items_response` — per-item Status array.
* Client wrappers: `publish_write_complete()`,
`delete_monitored_items(subscription_id, items)`.
6 new tests:
* `publish_write_complete_body_is_empty_wrapper` — body shape.
* `publish_write_complete_response_counts_item_write_complete_elements`
— counts 2 / 0 elements correctly.
* `publish_write_complete_response_zero_when_no_callbacks`.
* `delete_monitored_items_body_carries_subscription_id_and_items`.
* `delete_monitored_items_body_omits_require_id_field`.
* `delete_monitored_items_response_round_trip`.
Workspace: 701 tests pass (was 695, +6).
Stubbed for future iterations:
* ItemWriteComplete per-element decode (Status + WriteHandle) once
a live capture confirms the WCF DataContract XML wire form.
* Optional MonitoredItem fields (Active / TimeDeadband /
ValueDeadband / UserData) — same wire-byte uncertainty.
* Optional WriteValue fields (Comment / Timestamp / etc.).
All wire-byte caveats trace back to live-probe reconciliation
against an actual AVEVA VM.

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.
