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>
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.
