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/.

d11dd0520b Galaxy IPC unblock — live dev-box E2E path
Three root-cause fixes to get an elevated dev-box shell past session open
through to real MXAccess reads:

1. PipeAcl — drop BUILTIN\Administrators deny ACE. UAC's filtered token
   carries the Admins SID as deny-only, so the deny fired even from
   non-elevated admin-account shells. The per-connection SID check in
   PipeServer.VerifyCaller remains the real authorization boundary.

2. PipeServer — swap the Hello-read / VerifyCaller order. ImpersonateNamedPipeClient
   returns ERROR_CANNOT_IMPERSONATE until at least one frame has been read
   from the pipe; reading Hello first satisfies that rule. Previously the
   ACL deny-first path masked this race — removing the deny ACE exposed it.

3. GalaxyIpcClient — add a background reader + single pending-response
   slot. A RuntimeStatusChange event between OpenSessionRequest and
   OpenSessionResponse used to satisfy the caller's single ReadFrameAsync
   and fail CallAsync with "Expected OpenSessionResponse, got
   RuntimeStatusChange". The reader now routes response kinds (and
   ErrorResponse) to the pending TCS and everything else to a handler the
   driver registers in InitializeAsync. The Proxy was already set up to
   raise managed events from RaiseDataChange / RaiseAlarmEvent /
   OnHostConnectivityUpdate — those helpers had no caller until now.

4. RedundancyPublisherHostedService — swallow BadServerHalted while
   polling host.Server.CurrentInstance. StandardServer throws that code
   during startup rather than returning null, so the first poll attempt
   crashed the BackgroundService (and the host) before OnServerStarted
   ran. This race was latent behind the Galaxy init failure above.

Updates docs that described the Admins deny ACE + mandatory non-elevated
shells, and drops the admin-skip guards from every Galaxy integration +
E2E fixture that had them (IpcHandshakeIntegrationTests, EndToEndIpcTests,
ParityFixture, LiveStackFixture, HostSubprocessParityTests).

Adds GalaxyIpcClientRoutingTests covering the router's
request/response match, ErrorResponse, event-between-call, idle event,
and peer-close paths.

Verified live on the dev box against the p7-smoke cluster (gen 6):
driver registered=1 failedInit=0, Phase 7 bridge subscribed, OPC UA
server up on 4840, MXAccess read round-trip returns real data with
Status=0x00000000.

Task #112 — partial: Galaxy live stack is functional end-to-end. The
supplied test-galaxy.ps1 script still fails because the UNS walker
encodes TagConfig JSON as the tag's NodeId instead of the seeded TagId
(pre-existing; separate issue from this commit).

71339307fa Doc refresh (task #203) — driver docs split + drivers index + IHistoryProvider-aware HistoricalDataAccess
Restructure the driver-facing docs to match the OtOpcUa v2 multi-driver
reality (Galaxy, Modbus, S7, AB CIP, AB Legacy, TwinCAT, FOCAS, OPC UA Client
— 8 drivers total; Galaxy ships as three projects) and the capability-interface
architecture where every driver opts into IDriver + whichever of IReadable /
IWritable / ITagDiscovery / ISubscribable / IHostConnectivityProbe /
IPerCallHostResolver / IAlarmSource / IHistoryProvider / IRediscoverable it
supports. Doc scope follows the code: one-driver-specific docs scoped to that
driver, cross-driver concerns live once at the top level, per-driver specs
cross-link to docs/v2/driver-specs.md rather than duplicate.

What changed per file:

- docs/MxAccessBridge.md -> docs/drivers/Galaxy.md (git mv + rewrite): retitled
  "Galaxy Driver", reframed as one of seven drivers. Added Project Split table
  (Shared .NET Standard 2.0 / Host .NET 4.8 x86 / Proxy .NET 10) and Why
  Out-of-Process section citing both the MXAccess bitness constraint and Tier C
  stability isolation per docs/v2/plan.md section 4. Added IPC Transport
  section covering pipe naming, MessagePack framing, DACL that denies Admins,
  shared-secret handshake, heartbeat, and CallAsync<TReq,TResp> dispatch.
  Moved file paths from src/ZB.MOM.WW.LmxOpcUa.Host/MxAccess/* to
  src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Host/Backend/MxAccess/* and added the
  Shared + Proxy key-file tables. Added CapabilityInvoker + OTOPCUA0001
  analyzer callout. Cross-linked to drivers/README.md, Galaxy-Repository.md,
  HistoricalDataAccess.md.

- docs/GalaxyRepository.md -> docs/drivers/Galaxy-Repository.md (git mv +
  rewrite): retitled "Galaxy Repository — Tag Discovery for the Galaxy
  Driver", opened with a comparison table showing how every driver's
  ITagDiscovery source is different (AB CIP @tags walker, TwinCAT
  SymbolLoaderFactory, FOCAS CNC queries, OPC UA Client Session.Browse, etc).
  Repositioned GalaxyRepositoryService as the Galaxy driver's
  ITagDiscovery.DiscoverAsync implementation. Updated paths to
  Driver.Galaxy.Host/Backend/GalaxyRepository/*. Added IRediscoverable section
  covering the on-change-redeploy IPC path.

- docs/drivers/README.md (new): index with ground-truth driver table —
  project path, stability tier, wire library, capability-interface list, and
  one notable quirk per driver. Verified against the driver csproj files and
  class declarations on focas-pr3-remaining-capabilities (the most recent
  branch containing every driver). Galaxy gets its own dedicated docs; the
  other seven drivers cross-link to docs/v2/driver-specs.md. Lists the full
  Core.Abstractions capability surface, DriverTypeRegistry, CapabilityInvoker,
  and OTOPCUA0001 analyzer.

- docs/HistoricalDataAccess.md (rewrite): reframed around IHistoryProvider as
  a per-driver optional capability interface. Replaced v1 HistorianPluginLoader
  / AvevaHistorianPluginEntry plugin architecture with the v2 story —
  Historian.Aveva was merged into Driver.Galaxy.Host/Backend/Historian/ and
  IPC-forwarded through GalaxyProxyDriver. Documented all four IHistoryProvider
  methods (ReadRawAsync / ReadProcessedAsync / ReadAtTimeAsync /
  ReadEventsAsync), CapabilityInvoker wrapping with DriverCapability.HistoryRead,
  and the per-driver coverage matrix (Galaxy + OPC UA Client implement; the
  six protocol drivers don't and return BadHistoryOperationUnsupported). Kept
  the cluster-failover + health-counter + quality-mapping detail for the
  Galaxy Historian implementation. Flagged one gap: Proxy forwards all four
  history message kinds but the Host-side HistoryAggregateType -> AnalogSummary
  column mapping may surface GalaxyIpcException{Code="not-implemented"} on a
  given branch until the Phase 2 Galaxy out-of-process gate lands.

Driver list built against ground truth (src on focas-pr3-remaining-capabilities):
  Driver.Galaxy.{Shared,Host,Proxy}, Driver.Modbus, Driver.S7, Driver.AbCip,
  Driver.AbLegacy, Driver.TwinCAT, Driver.FOCAS, Driver.OpcUaClient.
Capability interface lists verified against each *Driver.cs class declaration.
Aveva Historian ported to Driver.Galaxy.Host/Backend/Historian/; no separate
Historian.Aveva assembly on v2 branches.
