Interface additions use C# default interface implementations that throw NotSupportedException — existing IHistoryProvider implementations keep compiling, only drivers whose backend carries the relevant capability override. This matches the 'capabilities are optional per driver' design already used by IHistoryProvider.ReadProcessedAsync's docs (Modbus / OPC UA Client drivers never had an event historian and the default-throw path lets callers see BadHistoryOperationUnsupported naturally). New HistoricalEvent record models one historian row (EventId, SourceName, EventTimeUtc + ReceivedTimeUtc — process vs historian-persist timestamps, Message, Severity mapped to OPC UA's 1-1000 range); HistoricalEventsResult pairs the event list with a continuation-point token for future batching. Both live in Core.Abstractions so downstream (Proxy, Host, Server) reference a single domain shape — no Shared-contract leak into the driver-facing interface.
GalaxyProxyDriver.ReadAtTimeAsync maps the domain DateTime[] to Unix-ms longs, calls CallAsync on the existing MessageKind.HistoryReadAtTimeRequest, and trusts the Host's one-sample-per-requested-timestamp contract (the Host pads with bad-quality snapshots for timestamps it can't interpolate; re-aligning on the Proxy side would duplicate the Host's interpolation policy logic). ReadEventsAsync does the same for HistoryReadEventsRequest; ToHistoricalEvent translates GalaxyHistoricalEvent (MessagePack-annotated, Unix-ms) to the domain record, explicitly tagging DateTimeKind.Utc on both timestamp fields so downstream serializers (JSON, OPC UA types) don't apply an unexpected local-time offset.
Tests — HistoricalEventMappingTests (3 new Proxy.Tests unit cases): every field maps correctly from wire to domain; null SourceName and null DisplayText preserve through the mapping (system events without a source come out with null so callers can distinguish them from alarm events); both timestamps come out as DateTimeKind.Utc (regression guard against a future refactor using DateTime.FromFileTimeUtc or similar that defaults to Unspecified). Driver.Galaxy.Proxy.Tests Unit suite: 17 pass / 0 fail (14 prior + 3 new). Full solution build clean, 0 errors.
Scope exclusions — DriverNodeManager HistoryRead service-handler wiring (on the OPC UA Server side, where HistoryReadAtTime and HistoryReadEvents service requests land) and the full-loop integration test (OPC UA client → server → IPC → Host → HistorianDataSource → back) are deferred to a focused follow-up PR. The capability surface is the load-bearing change; wiring the service handlers is mechanical in comparison and worth its own PR for reviewability. docs/v2/lmx-followups.md #1 updated with the split.

Polling chosen over event-driven for initial scope: simpler, matches Admin UI consumer cadence, avoids DriverHost lifecycle-event plumbing that doesn't exist today. Event-driven push for sub-heartbeat latency is a straightforward follow-up.
Admin.Services.HostStatusService left-joins DriverHostStatus against ClusterNode on NodeId so rows persist even when the ClusterNode entry doesn't exist yet (first-boot bootstrap case). StaleThreshold = 30s — covers one missed publisher heartbeat plus a generous buffer for clock skew and GC pauses. Admin Components/Pages/Hosts.razor — FleetAdmin-visible page grouped by cluster (handles the '(unassigned)' case for rows without a matching ClusterNode). Four summary cards (Hosts / Running / Stale / Faulted); per-cluster table with Node / Driver / Host / State + Stale-badge / Last-transition / Last-seen / Detail columns; 10s auto-refresh via IServiceScopeFactory timer pattern matching FleetStatusPoller + Fleet dashboard (PR 27). Row-class highlighting: Faulted → table-danger, Stale → table-warning, else default. State badge maps DriverHostState enum to bootstrap color classes. Sidebar link added between 'Fleet status' and 'Clusters'.
Server csproj adds Microsoft.EntityFrameworkCore.SqlServer 10.0.0 + registers OtOpcUaConfigDbContext in Program.cs scoped via NodeOptions.ConfigDbConnectionString (no Admin-style manual SQL raw — the DbContext is the only access path, keeps migrations owner-of-record).
Tests — HostStatusPublisherTests (4 new Integration cases, uses per-run throwaway DB matching the FleetStatusPollerTests pattern): publisher upserts one row per host from each probe-capable driver and skips non-probe drivers; second tick advances LastSeenUtc without creating duplicate rows (upsert pattern verified end-to-end); state change between ticks updates State AND StateChangedUtc (datetime2(3) rounds to millisecond precision so comparison uses 1ms tolerance — documented inline); MapState translates every HostState enum member. Server.Tests Integration: 4 new tests pass. Admin build clean, Admin.Tests Unit still 23 / 0. docs/v2/lmx-followups.md item #7 marked DONE with three explicit deferred items (event-driven push, failure-count column, SignalR fan-out).

No production code changes — pure additive test. Server.Tests Integration: 3 new tests pass; existing OpcUaServerIntegrationTests stays green (single-driver case still exercised there). Full Server.Tests Unit still 43 / 0. Deferred: multi-driver alarm-event case (two drivers each raising a GalaxyAlarmEvent, assert each condition lands on its owning instance's condition node) — needs a stub IAlarmSource and is worth its own focused PR.

Active Directory compatibility. LdapOptions xml-doc expanded with a cheat-sheet covering Server (DC FQDN), Port 389 vs 636, UseTls=true under AD LDAP-signing enforcement, dedicated read-only service account DN, sAMAccountName vs userPrincipalName vs cn trade-offs, memberOf DN shape (CN=Group,OU=...,DC=... with the CN= RDN stripped to become the GroupToRole key), and the explicit 'nested groups NOT expanded' call-out (LDAP_MATCHING_RULE_IN_CHAIN / tokenGroups is a future authenticator enhancement, not a config change). docs/security.md §'Active Directory configuration' adds a complete appsettings.json snippet with realistic AD group names (OPCUA-Operators → WriteOperate, OPCUA-Engineers → WriteConfigure, OPCUA-AlarmAck → AlarmAck, OPCUA-Tuners → WriteTune), LDAPS port 636, TLS on, insecure-LDAP off, and operator-facing notes on each field. LdapUserAuthenticatorAdCompatTests (5 unit guards): ExtractFirstRdnValue parses AD-style 'CN=OPCUA-Operators,OU=...,DC=...' DNs correctly (case-preserving — operators' GroupToRole keys stay readable); also handles mixed case and spaces in group names ('Domain Users'); also works against the OpenLDAP ou=<group>,ou=groups shape (GLAuth) so one extractor tolerates both memberOf formats common in the field; EscapeLdapFilter escapes the RFC 4515 injection set (\, *, (, ), \0) so a malicious login like 'admin)(cn=*' can't break out of the filter; default UserNameAttribute regression guard.
Test posture — Server.Tests Unit: 43 pass / 0 fail (38 prior + 5 new AD-compat guards). Server.Tests LiveLdap category: 6 pass / 0 fail against running GLAuth (would skip cleanly without). Server build clean, 0 errors, 0 warnings.
Deferred: the session-identity end-to-end check (drive a full OPC UA UserName session, then read a 'whoami' node to verify the role landed on RoleBasedIdentity). That needs a test-only address-space node and is scoped for a separate PR.

ModbusSimulatorFixture is a collection fixture so the 2s TCP probe runs once per run, not per test; SkipReason gets a clear operator-facing message ('start ModbusPal or override MODBUS_SIM_ENDPOINT'). Tests call Assert.Skip(sim.SkipReason) rather than silently returning — matches the test-plan convention and reads cleanly in CI logs. DL205Profile.BuildOptions deliberately disables the background probe loop since integration tests drive reads explicitly and the probe would race with assertions. Tag naming uses the DL205_ prefix so filter 'DisplayName~DL205' surfaces device-specific failures at a glance.
Project references: xunit.v3 + Shouldly + Microsoft.NET.Test.Sdk + xunit.runner.visualstudio (matches the existing Driver.Modbus.Tests unit project), project ref to src/Driver.Modbus. Registered in ZB.MOM.WW.OtOpcUa.slnx under tests/. ModbusPal/README.md documents the dev loop (install ModbusPal jar, load profile, start simulator, dotnet test), explains MODBUS_SIM_ENDPOINT override for real-PLC benchwork, and flags DL205.xmpp as the first profile to add in a follow-up PR.
dotnet test run against the scaffold (no simulator running) skips cleanly: 0 failed, 0 passed, 1 skipped, with the SkipReason surfaced. dotnet build clean (0 warnings, 0 errors). Updated docs/v2/modbus-test-plan.md to mark the scaffold PR done and renumbered future PRs from 'PR 27+' to 'PR 31+' to stay in sync with the actual PR chain.

Razor page layout: two tables (Rejected / Trusted) with Subject / Issuer / Thumbprint / Valid-window / Actions columns, status banner after each action with success or warning kind ('file missing' = another admin handled it), FleetAdmin-only via [Authorize(Roles=AdminRoles.FleetAdmin)]. Each action invokes LogActionAsync which Serilog-logs the authenticated admin user + thumbprint + action for an audit trail — DB-level ConfigAuditLog persistence is deferred because its schema is cluster-scoped and cert actions are cluster-agnostic; Serilog + CertTrustService's filesystem-op info logs give the forensic trail in the meantime. Sidebar link added to MainLayout between Reservations and the future Account page.
Tests — CertTrustServiceTests (9 new unit cases): ListRejected parses Subject + Thumbprint + store kind from a self-signed test cert written into rejected/certs/; rejected and trusted stores are kept separate; TrustRejected moves the file and the Rejected list is empty afterwards; TrustRejected with a thumbprint not in rejected returns false without touching trusted; DeleteRejected removes the file; UntrustCert removes from trusted only; thumbprint match is case-insensitive (operator UX); missing store directories produce empty lists instead of throwing DirectoryNotFoundException (pristine-install tolerance); a junk .der in the store is logged + skipped and the valid certs still surface (one bad file doesn't break the page). Full Admin.Tests Unit suite: 23 pass / 0 fail (14 prior + 9 new). Full Admin build clean — 0 errors, 0 warnings.
lmx-followups.md #3 marked DONE with a cross-reference to this PR and a note that flipping AutoAcceptUntrustedClientCertificates to false as the production default is a deployment-config follow-up, not a code gap — the Admin UI is now ready to be the trust gate.

Per decision #137 (dev env credentials documented openly in dev-environment.md; production uses Integrated Security / gMSA per decision #46 and never any value from this table). Section lives at the top of the doc immediately after Two Environment Tiers, so it's discoverable as the single source of truth for "what's actually running here right now".

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).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Record Phase 0 entry baseline: 820 passing, 2 pre-existing failures (Client.CLI.Tests.SubscribeCommandTests.Execute_PrintsSubscriptionMessage and Tests.MxAccess.MxAccessClientMonitorTests.Monitor_ProbeDataChange_PreventsStaleReconnect), 0 build errors, 167 build warnings. The two failures exist on v2 as of commit 1189dc8 and are unrelated to the rename. Phase 0 exit gate adapts the requirement to "failure count = baseline (2); pass count ≥ baseline (820)".
Branch-naming convention updated in implementation/overview.md and phase-0 doc: cannot use `v2/phase-N-slug` form because git treats `/` as path separator and `v2` already exists as a branch, blocking creation of any `v2/...` branch. Convention is now `phase-N-slug` (no v2/ prefix).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
OtOpcUa-side requirements all met or trivially met by v2: Basic256Sha256 + SignAndEncrypt + username token (transport security covers this), reject-and-trust cert workflow, endpoint URL must NOT include /discovery suffix (forum-documented failure mode), hostname-stable certs (decision #86 already enforces this since clients pin trust to ApplicationUri), OI Gateway service must NOT run under SYSTEM (deployment-guide concern). Two integrator-burden risks tracked: validation/GxP paperwork (no AVEVA blueprint exists for non-AVEVA upstream servers in Part 11 deployments — engage QA/regulatory in Year 1) and unpublished scale benchmarks (in-house benchmark required in Year 2 before cutover scheduling).
Phase 1 acceptance gains Task E.10 (decision #142): end-to-end AppServer-via-OI-Gateway smoke test against a Phase 1 OtOpcUa instance, catching AppServer-specific quirks (cert exchange, endpoint URL handling, service account, security mode combo) well before the Year 3 tier-3 cutover schedule. Non-blocking for Phase 1 exit if it surfaces only documentation-level fixes; blocking if it surfaces architectural incompatibility.
New file `docs/v2/aveva-system-platform-io-research.md` captures the full research with all source citations (AVEVA docs, Communications Drivers Pack readmes, Software Toolbox / InSource partner walkthroughs, Inductive Automation forum failure-mode reports). Plan.md decision log gains #141 and #142; Reference Documents section links the new doc.

ACL design defines NodePermissions bitmask flags covering Browse / Read / Subscribe / HistoryRead / WriteOperate / WriteTune / WriteConfigure / AlarmRead / AlarmAcknowledge / AlarmConfirm / AlarmShelve / MethodCall plus common bundles (ReadOnly / Operator / Engineer / Admin); 6-level scope hierarchy (Cluster / Namespace / UnsArea / UnsLine / Equipment / Tag) with default-deny + additive grants and Browse-implication on ancestors; per-LDAP-group grants in a new generation-versioned NodeAcl table edited via the same draft → diff → publish → rollback boundary as every other content table; per-session permission-trie evaluator with O(depth × group-count) cost cached for the lifetime of the session and rebuilt on generation-apply or LDAP group cache expiry; cluster-create workflow seeds a default ACL set matching the v1 LmxOpcUa LDAP-role-to-permission map for v1 → v2 consumer migration parity; Admin UI ACL tab with two views (by LDAP group, by scope), bulk-grant flow, and permission simulator that lets operators preview "as user X" effective permissions across the cluster's UNS tree before publishing; explicit Deny deferred to v2.1 since verbose grants suffice at v2.0 fleet sizes; only denied OPC UA operations are audit-logged (not allowed ones — would dwarf the audit log). Schema doc gains the NodeAcl table with cross-cluster invariant enforcement and same-generation FK validation; admin-ui.md gains the ACLs tab; phase-1 doc gains Task E.9 wiring this through Stream E plus a NodeAcl entry in Task B.1's DbContext list.
Dev-environment doc inventories every external resource the v2 build needs across two tiers per decision #99 — inner-loop (in-process simulators on developer machines: SQL Server local or container, GLAuth at C:\publish\glauth\, local dev Galaxy) and integration (one dedicated Windows host with Docker Desktop on WSL2 backend so TwinCAT XAR VM can run in Hyper-V alongside containerized oitc/modbus-server, plus WSL2-hosted Snap7 and ab_server, plus OPC Foundation reference server, plus FOCAS TestStub and FaultShim) — with concrete container images, ports, default dev credentials (clearly marked dev-only since production uses Integrated Security / gMSA per decision #46), bootstrap order for both tiers, network topology diagram, test data seed locations, and operational risks (TwinCAT trial expiry automation, Docker pricing, integration host SPOF mitigation, per-developer GLAuth config sync, Aveva license scoping that keeps Galaxy tests on developer machines and off the shared host).
Removes consumer cutover (ScadaBridge / Ignition / System Platform IO) from OtOpcUa v2 scope per decision #136 — owned by a separate integration / operations team, tracked in 3-year-plan handoff §"Rollout Posture" and corrections §C5; OtOpcUa team's scope ends at Phase 5. Updates implementation/overview.md phase index to drop the "6+" row and add an explicit "OUT of v2 scope" callout; updates phase-1 and phase-2 docs to reframe cutover as integration-team-owned rather than future-phase numbered.
Decisions #129–137 added: ACL model (#129), NodeAcl generation-versioned (#130), v1-compatibility seed (#131), denied-only audit logging (#132), two-tier dev environment (#133), Docker WSL2 backend for TwinCAT VM coexistence (#134), TwinCAT VM centrally managed / Galaxy on dev machines only (#135), cutover out of v2 scope (#136), dev credentials documented openly (#137).

Add Phase 2 detailed implementation plan (docs/v2/implementation/phase-2-galaxy-out-of-process.md) covering the largest refactor phase — moving Galaxy from the legacy in-process OtOpcUa.Host project into the Tier C out-of-process topology specified in driver-stability.md. Five work streams: A. Driver.Galaxy.Shared (.NET Standard 2.0 IPC contracts using MessagePack with hello-message version negotiation), B. Driver.Galaxy.Host (.NET 4.8 x86 separate Windows service that owns MxAccessBridge / GalaxyRepository / alarm tracking / GalaxyRuntimeProbeManager / Wonderware Historian SDK / STA thread + Win32 message pump with health probe / MxAccessHandle SafeHandle for COM lifetime / subscription registry with cross-host quality scoping / named-pipe IPC server with mandatory ACL + caller SID verification + per-process shared secret / memory watchdog with Galaxy-specific 1.5x baseline + 200MB floor + 1.5GB ceiling / recycle policy with 15s grace + WM_QUIT escalation to hard-exit / post-mortem MMF writer / Driver.Galaxy.FaultShim test-only assembly), C. Driver.Galaxy.Proxy (.NET 10 in-process driver implementing every capability interface, heartbeat sender on dedicated channel with 2s/3-miss tolerance, supervisor with respawn-with-backoff and crash-loop circuit breaker with escalating cooldown 1h/4h/24h, address space build via IAddressSpaceBuilder producing byte-equivalent v1 output), D. Retire legacy OtOpcUa.Host (delete from solution, two-service Windows installer, migrate appsettings.json Galaxy sections to central DB DriverConfig blob), E. Parity validation (v1 IntegrationTests pass count = baseline failures = 0, scripted Client.CLI walkthrough output diff vs v1 only differs in timestamps/latency, four named regression tests for the 2026-04-13 stability findings). Compliance script verifies all eight Tier C cross-cutting protections have named passing tests. Decision #128 captures the survey-removal; cross-references added to plan.md Reference Documents and overview.md phase index.

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.

Add ServerCapabilities/OperationLimits node, enable diagnostics, add OnModifyMonitoredItemsComplete
override for DA compliance. Wire shelving, enable/disable, confirm, and addcomment handlers on
alarm conditions with LocalTime/Quality event fields for Part 9 compliance. Add Aes128/Aes256
security profiles, X.509 certificate authentication, and AUDIT-prefixed auth logging. Fix flaky
probe monitor test. Update docs for all changes.

Implements Client.Shared (IOpcUaClientService with connection lifecycle, failover,
browse, read/write, subscriptions, alarms, history, redundancy), Client.CLI (8 CliFx
commands mirroring tools/opcuacli-dotnet), and Client.UI (Avalonia desktop app with
tree browser, read/write, subscriptions, alarms, and history tabs). All three target
.NET 10 and are covered by 249 unit tests.

Map LDAP groups to custom OPC UA role NodeIds on RoleBasedIdentity.GrantedRoleIds
during authentication, replacing the username-to-role side cache. Split ReadWrite
into WriteOperate/WriteTune/WriteConfigure so write access is gated per Galaxy
security classification. AnonymousCanWrite now behaves consistently regardless
of LDAP state.

Previously alarms were only reported to the immediate parent node and the Server node.
Now ReportEventUpNotifierChain walks the full parent chain so clients subscribed at
TestArea see alarms from TestMachine_001, and EventNotifier is set on all ancestors
of alarm-containing nodes.

- Remove ConfigUserAuthenticationProvider and Users property — LDAP is the only auth mechanism
- Fix historian quality mapping to use existing QualityMapper (OPC DA quality bytes, not custom mapping)
- Add AppRoles constants, unify HasWritePermission/HasAlarmAckPermission into shared HasRole helper
- Hoist write permission check out of per-item loop, eliminate redundant _ldapRolesEnabled field
- Update docs (Configuration.md, Security.md, OpcUaServer.md, HistoricalDataAccess.md)

All commands gain --failover-urls (-F) to specify alternate endpoints.
Short-lived commands try each URL in order on initial connect. The
subscribe command monitors KeepAlive and automatically reconnects to
the next available server, re-creating the subscription on failover.
Verified with live service start/stop: primary down triggers failover
to secondary, primary restart allows failback.
