New module crates/mxaccess-galaxy/src/sql_resolver.rs (~480 LoC) gated behind the existing galaxy-resolver Cargo feature. Adds SqlTagResolver + SqlUserResolver, both constructed via from_ado_string(&str) accepting the same connection-string shape the .NET reference uses by default (Server=localhost;Database=ZB;Integrated Security=True; Encrypt=False;TrustServerCertificate=True). Integrated Security=True resolves to Windows auth via tiberius's winauth feature. Each top-level call (resolve / browse / resolve_by_guid / resolve_by_name) opens a fresh Client<Compat<TcpStream>> and drops it on return — matches the .NET `await using` lifecycle at GalaxyRepositoryTagResolver.cs:93-95. tiberius's Client::query only accepts positional @P1..@PN placeholders (delegates to sp_executesql); the canonical RESOLVE_SQL / BROWSE_SQL / USER_BY_GUID_SQL / USER_BY_NAME_SQL constants are rewritten once-per-process via OnceLock<String> (@objectTagName → @P1, etc.). The unrewritten constants stay byte-identical with the .NET reference for ad-hoc diagnostic copy/paste. read_metadata mirrors ReadMetadata (cs:149-165) byte-by-byte: signed smallint → i16 widened to u16 for platform/engine/object IDs (matches the .NET checked((ushort)reader.GetInt16(N)) shape), int → i32 checked-cast to i16 for property_id, nullable nvarchar for primitive_name. read_user_profile mirrors ReadProfile (cs:76-85) including the roles_text blob → parse_role_blob round-trip. Deps added (gated): tiberius 0.12 (default-features = false; tds73 + rustls + winauth — no chrono / rust_decimal pulled), tokio-util's compat feature for the futures-rs ↔ tokio AsyncRead bridge, futures-util for TryStreamExt::try_next. Default-feature build still pulls only mxaccess-codec + async-trait + thiserror + uuid (slim foot-print preserved per the design doc's intent). New `live` feature on this crate (`live = ["galaxy-resolver"]`) for parity with the workspace pattern. 11 offline unit tests pin: SQL named→positional rewriting (no @named left, @P1/@P2/@P3 present), line-count preserved, ado-string acceptance (default Galaxy shape parses, garbage rejected), input validation (max_rows=0 rejected, empty LIKE rejected, empty user_name rejected, all checked before connect attempt). Two #[cfg(feature = "live")] #[ignore]'d tests round-trip against a real Galaxy DB (gated on MX_LIVE + MX_GALAXY_DB env vars per tools/Setup-LiveProbeEnv.ps1). Live verification on this host: live_resolve_test_child_object_test_int and live_browse_test_child_object both pass against the local AVEVA install — TestChildObject.TestInt resolves with mx_data_type=2 (Int32), is_array=false. Closes F14 in design/followups.md. 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).
