Doc refresh (task #205 ) — requirements updated for multi-driver OtOpcUa three-process deploy
...
Per-file summary:
- docs/reqs/OpcUaServerReqs.md — rewritten driver-agnostic. OPC-001..OPC-013 re-scoped to multi-driver address-space composition + capability dispatch; OPC-014 AuthorizationGate + permission trie; OPC-015 dynamic ServiceLevel via RedundancyCoordinator; OPC-017 surgical generation-apply rebuild; OPC-012 capability dispatch via CapabilityInvoker (decision #143 idempotence-aware retry); OPC-013 per-host Polly isolation (decision #144 ); OPC-019 OpenTelemetry metrics. Transport-security profile matrix (OPC-010) + UserName/LDAP (OPC-011) preserved.
- docs/reqs/GalaxyRepositoryReqs.md — scope clarified as Galaxy-driver-only (not platform). GR-001..GR-004 tied to ITagDiscovery.DiscoverAsync + IRediscoverable; all SQL runs inside OtOpcUa.Galaxy.Host and streams to Proxy via named pipe. GR-008 capability wrapping via CapabilityInvoker added. Cross-links to docs/v2/driver-specs.md + docs/GalaxyRepository.md.
- docs/reqs/MxAccessClientReqs.md — scope clarified as Galaxy-Host-only. MXA-001..MXA-009 preserved (STA pump, register/unregister, subscription refcount, auto-reconnect, probe, COM cleanup, operation metrics, error translation). MXA-010 Proxy-side capability wrapping + MXA-011 pipe ACL + per-process shared secret (OTOPCUA_ALLOWED_SID / OTOPCUA_GALAXY_SECRET) added.
- docs/reqs/ServiceHostReqs.md — rewritten for three-process deployment. Shared section (SVC-SHARED-001/002) for Serilog + bootstrap-only appsettings. SRV-* for OtOpcUa.Server (net10 x64, Microsoft.Extensions.Hosting + AddWindowsService, in-process driver hosting, redundancy-node bootstrap). ADM-* for OtOpcUa.Admin (Blazor Server, cookie+LDAP auth, CanEdit/CanPublish policies, sole DB writer, Prometheus /metrics, audit logging). GHX-* for OtOpcUa.Galaxy.Host (TopShelf, net48 x86, named-pipe IPC bootstrap, STA backend lifecycle, crash handling tied to supervisor).
- docs/reqs/ClientRequirements.md — restructured as numbered, verifiable requirements. SHR-* for Client.Shared (single IOpcUaClientService, ConnectionSettings, failover, cross-platform certs, type-coercing write, UI-thread neutrality). CLI-001..CLI-011 cover connect/read/write/browse/subscribe/historyread/alarms/redundancy. UI-001..UI-008 cover connection panel, tree browser, each tab, connection-state reflection, cross-platform build. Reference design content (IOpcUaClientService shape, models, view-model map, mock layout) preserved.
- docs/reqs/StatusDashboardReqs.md — retired cleanly. Replaced with a pointer to docs/v2/admin-ui.md + HLR-015 / HLR-016 / HLR-017 / ADM-*. Mapping table shows each retired DASH-001..DASH-009 requirement's replacement (live cluster-node view via SignalR, Prometheus metrics, driver-instance detail views, etc.). Note that a formal AdminUiReqs.md can be written later if needed for cert compliance.
HighLevelReqs.md was already at the target shape (HLR-001..HLR-018 with Revision header noting retired HLR-009) as of commit f217636; verified identical and no additional edit required.

Implement LmxOpcUa server — all 6 phases complete
...
Full OPC UA server on .NET Framework 4.8 (x86) exposing AVEVA System
Platform Galaxy tags via MXAccess. Mirrors Galaxy object hierarchy as
OPC UA address space, translating contained-name browse paths to
tag-name runtime references.
Components implemented:
- Configuration: AppConfiguration with 4 sections, validator
- Domain: ConnectionState, Quality, Vtq, MxDataTypeMapper, error codes
- MxAccess: StaComThread, MxAccessClient (partial classes), MxProxyAdapter
using strongly-typed ArchestrA.MxAccess COM interop
- Galaxy Repository: SQL queries (hierarchy, attributes, change detection),
ChangeDetectionService with auto-rebuild on deploy
- OPC UA Server: LmxNodeManager (CustomNodeManager2), LmxOpcUaServer,
OpcUaServerHost with programmatic config, SecurityPolicy None
- Status Dashboard: HTTP server with HTML/JSON/health endpoints
- Integration: Full 14-step startup, graceful shutdown, component wiring
175 tests (174 unit + 1 integration), all passing.
