Lands the user-resolver half of M3 stream A. Pure-Rust foundation — the tiberius-backed SQL impl is logged as F14 and stays gated behind the existing galaxy-resolver Cargo feature. New - role_blob.rs (~270 LoC, 12 tests including a garbage-between-roles edge case) — port of ParseRoleBlob (cs:87-133). Sliding-window scan over hex-decoded UTF-16LE bytes; rejects non-printable code units; case-insensitive dedup. Pure function, no I/O. - user.rs (~290 LoC, 8 tests including 4 tokio-driven InMemoryUserResolver cases) — GalaxyUserProfile (port of cs:5-11) + from_columns helper bridging into role_blob + UserResolver async trait + UserResolverError with NotFound / Backend variants. - sql.rs additions: USER_SELECT_SQL + USER_BY_GUID_SQL + USER_BY_NAME_SQL constants (port of cs:135-148). Inline concatcp! macro composes the base SELECT with each WHERE clause at compile time without pulling const_format. Cargo.toml: added uuid (Galaxy user_guid is a uniqueidentifier). design/followups.md: added F14 (P2) for the tiberius-backed SQL impl behind the galaxy-resolver feature. Test count delta: 427 -> 446 (+19; mxaccess-galaxy 30 -> 49). All four DoD gates green. 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.
