F18 (M5 master) gains an "M5 STATUS" block right after the DoD checklist showing the live end-to-end win (commit `9063f10`, TestChildObject.TestInt round-trips with payload [99,0,0,0]) and ticking each DoD bullet: - ✅ Live `asb-subscribe` succeeds. - ⚠️ Wire request bytes match .NET byte-for-byte; response parity uses the F30 dict-id resolution post-pass + chunked-Bytes concatenation instead of strict byte equality (functionally equivalent — both decode to the same logical XML). - ⚠️ Type matrix: only Int32 verified live; Bool/Float/Double/ String/DateTime/Duration/arrays pending sample tags. Tracked under new F32. - ✅ build/test/clippy green (711 tests). Followup churn: - F30 + F31 moved to ## Resolved with proper "Resolved: <date> (commit `<hash>`)" headers. F30 was the unblocker for F31 — without read-side dict-id resolution we couldn't see `<resultCodeField>1</>` in the response. - F28 status header updated to "PARTIALLY RESOLVED": the five [XmlSerializerFormat] ops (AuthenticateMe, Disconnect, KeepAlive, RegisterItems, UnregisterItems) plus DH params + dynamic-dict management all landed; Read/Write/Subscribe/Publish still sign over NBFX wire bytes via the legacy fallback. Severity demoted P0 → P2 because the live registry has empty `hashAlgorithm` and unsigned ops work in practice; promote back if that changes. - F29 reaffirmed P2 (latent NBFS dict-id drift, no live impact). - New F32 captures the type-matrix expansion as the only remaining P1 item for full M5 closeout. No code change in this commit — design doc only. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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).
