Ports the curated subset of the `[MC-NBFS]` §2.2 static dictionary to `mxaccess-asb-nettcp::nbfs`. Approximately 80 entries covering SOAP 1.2 envelope tokens, WS-Addressing 1.0 tokens, WS-RM, WS-Security, WS-Trust/SecureConversation, XML Schema Instance primitives, plus the common XML element / attribute names captured in `analysis/proxy/mxasbclient-*` traces. API: * `STATIC_ENTRIES: &[StaticEntry]` — sorted-by-id table; one-line extension when wire captures show new IDs. * `lookup_static(id) -> Option<&'static str>` — binary-search lookup for the F21 NBFX decoder. * `position_of_static(value) -> Option<u32>` — `OnceLock`-cached reverse lookup for the F21 NBFX encoder. Lookups outside the curated subset return `None`. The NBFX decoder will surface that as a typed `UnknownStaticDictionaryId` error so the caller knows to either extend the table or fall through to the inline-string path. The full 487-entry table is bounded but tedious; the deliberate subset keeps source size down while remaining extensible. ASB-specific contract strings (`http://ASB.IDataV2`, `http://asb.contracts/20111111`, the IASBIDataV2 operation actions, etc.) are intentionally **not** in the static dictionary — they live in the per-session dynamic dictionary that the F21 NBFX codec builds up via `DictionaryString` records. 6 unit tests cover monotonic-id invariant, known-id lookup, unknown-id rejection, round-trip lookup consistency, and the empty-string slot at id=142.

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).
