Joseph Doherty 006af51768 docs: post-PR-7.2 cleanup — audit + three-track scrub
Audit (three parallel agent passes) found 43 markdown files carrying
stale references to the deleted Galaxy.Host/Proxy/Shared projects
after the v2-mxgw merge. This commit lands the prioritized fixes.

Track 1 — high-traffic in-place rewrites (3 files, ~454 lines deleted)
- README.md (202 → 91 lines): drops .NET 4.8 / x86 / TopShelf install
  text; leads with the multi-driver .NET 10 server identity and points
  at scripts/install/Install-Services.ps1 and the parity rig.
- docs/v2/driver-specs.md §1 Galaxy (~289 → ~66 lines): replaces the
  Tier-C out-of-process spec with a Tier-A in-process description
  matching the current GalaxyDriver code, with the four-section
  GalaxyDriverOptions JSON shape pulled verbatim from
  Config/GalaxyDriverOptions.cs.
- docs/drivers/Galaxy.md (211 → 92 lines): full rewrite around the
  current Browse/Runtime/Health/Config sub-folders.

Track 2 — historical banners (5 files)
- lmx_mxgw.md, lmx_mxgw_impl.md, lmx_backend.md,
  docs/v2/Galaxy.ParityMatrix.md,
  docs/v2/implementation/phase-2-galaxy-out-of-process.md each get a
  " Completed 2026-04-30 — historical record" banner block. lmx_mxgw.md
  also fixes two dead links (`docs/Galaxy.Driver.md` and
  `docs/v2/Galaxy.Driver.md`) → `docs/drivers/Galaxy.md`.

Track 3 — v1 archive sweep (10 git mv + 1 new index + 2 in-place scrubs)
- Moved 10 v1 docs under docs/v1/ preserving subpath structure:
  AlarmTracking, Configuration, DataTypeMapping, HistoricalDataAccess,
  Subscriptions (top-level); drivers/Galaxy-Repository,
  drivers/Galaxy-Test-Fixture; reqs/GalaxyRepositoryReqs,
  reqs/MxAccessClientReqs, reqs/ServiceHostReqs.
- New docs/v1/README.md is the shared archive banner + per-file table.
- docs/README.md repointed to the v1 paths and updated to reflect the
  v2 two-process deploy shape (Server + Admin + optional
  OtOpcUaWonderwareHistorian).
- docs/v2/Galaxy.ParityRig.md got a historical banner + four inline
  scrubs marking the OtOpcUaGalaxyHost service / Driver.Galaxy.Host
  EXE / Driver.Galaxy.ParityTests project as deleted-in-PR-7.2.

The repo's live-reading surface (README + CLAUDE.md + docs/v2/) now
describes only the post-PR-7.2 architecture. v1 docs are preserved as
a labelled archive under docs/v1/.

v1 documentation archive

This folder contains documentation that described the original v1 in-process MXAccess architecture (Galaxy.Host + Galaxy.Proxy + Galaxy.Shared three-project split, .NET 4.8 x86 + COM apartment, the OtOpcUaGalaxyHost Windows service). That architecture was retired in PR 7.2 (merged 2026-04-30 at commit ae7106d). These docs are kept as the historical record of how the system worked before the v2-mxgw migration; treat their content as accurate at the time of writing, NOT as current state.

For current architecture see:

  • CLAUDE.md — agent-facing v2 overview
  • docs/drivers/Galaxy.md — current Galaxy driver doc
  • docs/v2/Galaxy.ParityRig.md — current testing setup
  • docs/v2/Galaxy.Performance.md — observability + perf
  • lmx_mxgw.md (in repo root) — design rationale for the migration
File What it covered
AlarmTracking.md v1 alarm-tracking flow through the in-process MXAccess client
Configuration.md v1 server configuration (OTOPCUA_GALAXY_* env vars now live in mxaccessgw config)
DataTypeMapping.md Galaxy mx_data_type → OPC UA type mapping (still accurate as a reference; the live mapping logic is in src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy/Browse/DataTypeMap.cs)
HistoricalDataAccess.md v1 IHistoryProvider on the Host side; current path is the server-level HistoryRouter + Wonderware sidecar
Subscriptions.md v1 MXAccess subscription mechanics; current path uses gateway StreamEvents
drivers/Galaxy-Repository.md v1 Host-side ZB SQL repository client; the gateway owns this path now
drivers/Galaxy-Test-Fixture.md v1 test-fixture setup (parity tests + Galaxy.Host EXE spawn)
reqs/GalaxyRepositoryReqs.md, reqs/MxAccessClientReqs.md Original Phase 0 requirements; satisfied in mxaccessgw repo today
reqs/ServiceHostReqs.md Service-hosting requirements including OtOpcUaGalaxyHost (GHX-* section); only OtOpcUa server hosting remains in scope post-7.2
