Renames all 11 projects (5 src + 6 tests), the .slnx solution file, all source-file namespaces, all axaml namespace references, and all v1 documentation references in CLAUDE.md and docs/*.md (excluding docs/v2/ which is already in OtOpcUa form). Also updates the TopShelf service registration name from "LmxOpcUa" to "OtOpcUa" per Phase 0 Task 0.6.
Preserves runtime identifiers per Phase 0 Out-of-Scope rules to avoid breaking v1/v2 client trust during coexistence: OPC UA `ApplicationUri` defaults (`urn:{GalaxyName}:LmxOpcUa`), server `EndpointPath` (`/LmxOpcUa`), `ServerName` default (feeds cert subject CN), `MxAccessConfiguration.ClientName` default (defensive — stays "LmxOpcUa" for MxAccess audit-trail consistency), client OPC UA identifiers (`ApplicationName = "LmxOpcUaClient"`, `ApplicationUri = "urn:localhost:LmxOpcUaClient"`, cert directory `%LocalAppData%\LmxOpcUaClient\pki\`), and the `LmxOpcUaServer` class name (class rename out of Phase 0 scope per Task 0.5 sed pattern; happens in Phase 1 alongside `LmxNodeManager → GenericDriverNodeManager` Core extraction). 23 LmxOpcUa references retained, all enumerated and justified in `docs/v2/implementation/exit-gate-phase-0.md`.
Build clean: 0 errors, 30 warnings (lower than baseline 167). Tests at strict improvement over baseline: 821 passing / 1 failing vs baseline 820 / 2 (one flaky pre-existing failure passed this run; the other still fails — both pre-existing and unrelated to the rename). `Client.UI.Tests`, `Historian.Aveva.Tests`, `Client.Shared.Tests`, `IntegrationTests` all match baseline exactly. Exit gate compliance results recorded in `docs/v2/implementation/exit-gate-phase-0.md` with all 7 checks PASS or DEFERRED-to-PR-review (#7 service install verification needs Windows service permissions on the reviewer's box).

The aahClientManaged SDK is now isolated in ZB.MOM.WW.LmxOpcUa.Historian.Aveva and loaded via HistorianPluginLoader from a Historian/ subfolder only when enabled, removing the SDK from Host's compile-time and deploy-time surface.

Move subscribe/unsubscribe I/O outside lock(Lock) in SyncAddressSpace to avoid
blocking all OPC UA operations during rebuilds. Replace blocking ReadAsync calls
for alarm priority/description in dispatch loop with cached subscription values.
Extract IHistorianConnectionFactory so EnsureConnected can be tested without the
SDK runtime — adds 5 connection lifecycle tests (failure, timeout, reconnect,
state resilience, dispose-after-failure). All stability review findings and test
coverage gaps are now fully resolved.

Linter/formatter pass across the full codebase. Restores required partial
keyword on AXAML code-behind classes that the formatter incorrectly removed.

Tests verify nodes can be added/removed from the OPC UA server at
runtime by mutating FakeGalaxyRepository and triggering a rebuild.
Uses real OPC UA client sessions to browse, subscribe, and observe
changes.
Tests cover:
- Browse initial hierarchy via OPC UA client
- Add object at runtime → new node appears on browse
- Remove object → node disappears from browse
- Subscribe to node, then remove it → publishes Bad quality
- Surviving nodes still browsable after partial rebuild
- Add/remove individual attributes at runtime
Infrastructure:
- OpcUaTestClient helper for programmatic OPC UA client connections
- OpcUaServerFixture updated with GalaxyRepository/MxProxy accessors
- OpcUaService.TriggerRebuild() exposed for test-driven rebuilds
- Namespace index resolved dynamically via session namespace table

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.
