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.

design/ — Rust port architectural plan
This folder is the design contract for the Rust replacement of AVEVA/Wonderware MXAccess. It is the gap between the .NET reference in src/ and the Rust crates that will be written under a sibling rust/ workspace (per CLAUDE.md).
The folder is structured as a small set of focused documents. Read in order; each builds on the previous.
| File | Purpose |
|---|---|
00-overview.md |
Mission, two-layer goal, architectural principles, non-goals |
10-raw-layer.md |
Byte-accurate raw MXAccess layer (codec + transport + session) |
20-async-layer.md |
Idiomatic Tokio async layer on top of the raw layer |
30-crate-topology.md |
Cargo workspace, crates, dependencies, build/test commands |
40-protocol-invariants.md |
Bill of materials: IIDs, opnums, envelope/handle bytes |
50-error-model.md |
MxStatus, error types, panic/cancellation policy |
60-roadmap.md |
Milestones M0..M6, validation strategy |
70-risks-and-open-questions.md |
Parity gaps, unproven flows, cross-platform constraints |
dependencies.md |
Cross- and within-milestone parallelism map; agent budget per phase |
review.md |
Adversarial review log (BLOCKER/MAJOR/MINOR/NIT findings, all resolved) |
prompt.md |
/loop driver prompt for autonomous M2–M6 execution |
followups.md |
Open / resolved deferred work items; auto-triaged by prompt.md Step 0 (created on first /loop run if missing) |
The design is grounded in the .NET reference at src/ and the protocol artifacts in docs/, analysis/, and captures/. Do not introduce protocol behavior in these documents that is not already proven in the reference. When adding a new claim about wire format, cite either:
- a
.csfile path insrc/MxNativeCodec/,src/MxNativeClient/, orsrc/MxAsbClient/, or - a
docs/*.mdspec file, or - a
captures/0NN-frida-*directory oranalysis/frida/*.tsvrow.
This folder is documentation, not code. When the Rust workspace is created, the design here is the contract it must satisfy. When evidence in captures/ invalidates a design decision here, update the design first, then the code.
Reading order
- New contributor: 00 → 30 → 10 → 40 → 20 → 50 → 60 → 70.
- Protocol question: 40 first, then the relevant section of 10.
- API question: 20 first, then 50.
- Planning a milestone: 60 first, cross-reference 70 for blockers.
- Scheduling concurrent work:
dependencies.mdfor the per-phase parallelism map. - Driving M2–M6 autonomously via
/loop:prompt.md(and thefollowups.mdtriage log it maintains).
