Joseph Doherty 8464e3f376 Phase 3 PR 33 — DriverHostStatus entity + EF migration (data-layer for LMX #7). New DriverHostStatus entity with composite key (NodeId, DriverInstanceId, HostName) persists each server node's per-host connectivity view — one row per (server node, driver instance, probe-reported host), which means a redundant 2-node cluster with one Galaxy driver reporting 3 platforms produces 6 rows because each server node owns its own runtime view of the shared host topology, not 3. Fields: NodeId (64), DriverInstanceId (64), HostName (256 — fits Galaxy FQDNs and Modbus host:port strings), State (DriverHostState enum — Unknown/Running/Stopped/Faulted, persisted as nvarchar(16) via HasConversion<string> so DBAs inspecting the table see readable state names not ordinals), StateChangedUtc + LastSeenUtc (datetime2(3) — StateChangedUtc tracks actual transitions while LastSeenUtc advances on every publisher heartbeat so the Admin UI can flag stale rows from a crashed Server independent of State), Detail (nullable 1024 — exception message from the driver's probe when Faulted, null otherwise). ...

DriverHostState enum lives in Configuration.Enums/ rather than reusing Core.Abstractions.HostState so the Configuration project stays free of driver-runtime dependencies (it's referenced by both the Admin process and the Server process, so pulling in the driver-abstractions assembly to every Admin build would be unnecessary weight). The server-side publisher hosted service (follow-up PR 34) will translate HostStatusChangedEventArgs.NewState to this enum on every transition.
No foreign key to ClusterNode — a Server may start reporting host status before its ClusterNode row exists (first-boot bootstrap), and we'd rather keep the status row than drop it. The Admin-side service that renders the dashboard will left-join on NodeId when presenting. Two indexes declared: IX_DriverHostStatus_Node drives the per-cluster drill-down (Admin UI joins ClusterNode on ClusterId to pick which NodeIds to fetch), IX_DriverHostStatus_LastSeen drives the stale-row query (now - LastSeen > threshold).
EF migration AddDriverHostStatus creates the table + PK + both indexes. Model snapshot updated. SchemaComplianceTests expected-tables list extended. DriverHostStatusTests (3 new cases, category SchemaCompliance, uses the shared fixture DB): composite key allows same (host, driver) across different nodes AND same (node, host) across different drivers — both real-world cases the publisher needs to support; upsert-in-place pattern (fetch-by-composite-PK, mutate, save) produces one row not two — the pattern the publisher will use; State enum persists as string not int — reading the DB via ADO.NET returns 'Faulted' not '3'.
Configuration.Tests SchemaCompliance suite: 10 pass / 0 fail (7 prior + 3 new). Configuration build clean. No Server or Admin code changes yet — publisher + /hosts page are PR 34.

Phase 3 PR 29 — Account/session page expanding the minimal sidebar role display into a dedicated /account route. Shows the authenticated operator's identity (username from ClaimTypes.NameIdentifier, display name from ClaimTypes.Name), their Admin roles as badges (from ClaimTypes.Role), the raw LDAP groups that mapped to those roles (from the 'ldap_group' claim added by Login.razor at sign-in), and a capability table listing each Admin capability with its required role and a Yes/No badge showing whether this session has it. Capability list mirrors the Program.cs authorization policies + each page's [Authorize] attribute so operators can self-service check whether their session has access without trial-and-error navigation — capabilities covered: view clusters + fleet status (all roles), edit configuration drafts (ConfigEditor or FleetAdmin per CanEdit policy), publish generations (FleetAdmin per CanPublish policy), manage certificate trust (FleetAdmin per PR 28 Certificates page attribute), manage external-ID reservations (ConfigEditor or FleetAdmin per Reservations page attribute).

Phase 3 PR 16 — concrete OPC UA server scaffolding with AlarmConditionState materialization. Introduces the OPCFoundation.NetStandard.Opc.Ua.Server package (v1.5.374.126, same version the v1 stack already uses) and two new server-side classes: DriverNodeManager : CustomNodeManager2 is the concrete realization of PR 15's IAddressSpaceBuilder contract — Folder() creates FolderState nodes under an Organizes hierarchy rooted at ObjectsFolder > DriverInstanceId; Variable() creates BaseDataVariableState with DataType mapped from DriverDataType (Boolean/Int32/Float/Double/String/DateTime) + ValueRank (Scalar or OneDimension) + AccessLevel CurrentReadOrWrite; AddProperty() creates PropertyState with HasProperty reference. Read hook wires OnReadValue per variable to route to IReadable.ReadAsync; Write hook wires OnWriteValue to route to IWritable.WriteAsync and surface per-tag StatusCode. MarkAsAlarmCondition() materializes an OPC UA AlarmConditionState child of the variable, seeded from AlarmConditionInfo (SourceName, InitialSeverity → UA severity via Low=250/Medium=500/High=700/Critical=900, InitialDescription), initial state Enabled + Acknowledged + Inactive + Retain=false. Returns an IAlarmConditionSink whose OnTransition updates alarm.Severity/Time/Message and switches state per AlarmType string ('Active' → SetActiveState(true) + SetAcknowledgedState(false) + Retain=true; 'Acknowledged' → SetAcknowledgedState(true); 'Inactive' → SetActiveState(false) + Retain=false if already Acked) then calls alarm.ReportEvent to emit the OPC UA event to subscribed clients. Galaxy's GalaxyAlarmTracker (PR 14) now lands at a concrete AlarmConditionState node instead of just raising an unobserved C# event. OtOpcUaServer : StandardServer wires one DriverNodeManager per DriverHost.GetDriver during CreateMasterNodeManager — anonymous endpoint, no security profile (minimum-viable; LDAP + security-profile wire-up is the next PR). DriverHost gains public GetDriver(instanceId) so the server can enumerate drivers at startup. NestedBuilder inner class in DriverNodeManager implements IAddressSpaceBuilder by temporarily retargeting the parent's _currentFolder during each call so Folder→Variable→AddProperty land under the correct subtree — not thread-safe if discovery ran concurrently, but GenericDriverNodeManager.BuildAddressSpaceAsync is sequential per driver so this is safe by construction. NuGet audit suppress for GHSA-h958-fxgg-g7w3 (moderate-severity in OPCFoundation.NetStandard.Opc.Ua.Core 1.5.374.126; v1 stack already accepts this risk on the same package version). PR 16 is scoped as scaffolding — the actual server startup (ApplicationInstance, certificate config, endpoint binding, session management wiring into OpcUaServerService.ExecuteAsync) is deferred to a follow-up PR because it needs ApplicationConfiguration XML + optional-cert-store logic that depends on per-deployment policy decisions. The materialization shape is complete: a subsequent PR adds 100 LOC to start the server and all the already-written IAddressSpaceBuilder + alarm-condition + read/write wire-up activates end-to-end. Full solution: 0 errors, 152 unit tests pass (no new tests this PR — DriverNodeManager unit testing needs an IServerInternal mock which is heavyweight; live-endpoint integration tests land alongside the server-startup PR).

Phase 3 PR 15 — alarm-condition contract in IAddressSpaceBuilder + wire OnAlarmEvent through GenericDriverNodeManager. IAddressSpaceBuilder.IVariableHandle gains MarkAsAlarmCondition(AlarmConditionInfo) which returns an IAlarmConditionSink. AlarmConditionInfo carries SourceName/InitialSeverity/InitialDescription. Concrete address-space builders (the upcoming PR 16 OPC UA server backend) materialize a sibling AlarmConditionState node on the first call; the sink receives every lifecycle transition the generic node manager forwards. GenericDriverNodeManager gains a CapturingBuilder wrapper that transparently wraps every Folder/Variable call — the wrapper observes MarkAsAlarmCondition calls without participating in materialization, captures the resulting IAlarmConditionSink into an internal source-node-id → sink ConcurrentDictionary keyed by IVariableHandle.FullReference. After DiscoverAsync completes, if the driver implements IAlarmSource the node manager subscribes to OnAlarmEvent and routes every AlarmEventArgs to the sink registered for args.SourceNodeId — unknown source ids are dropped silently (may belong to another driver or to a variable the builder chose not to flag). Dispose unsubscribes the forwarder to prevent dangling invocation-list references across node-manager rebuilds. GalaxyProxyDriver.DiscoverAsync now calls handle.MarkAsAlarmCondition(new AlarmConditionInfo(fullName, AlarmSeverity.Medium, null)) on every attr.IsAlarm=true variable — severity seed is Medium because the live Priority byte arrives through the subsequent GalaxyAlarmEvent stream (which PR 14's GalaxyAlarmTracker now emits); the Admin UI sees the severity update on the first transition. RecordingAddressSpaceBuilder in Driver.Galaxy.E2E gains a RecordedAlarmCondition list + a RecordingSink implementation that captures AlarmEventArgs for test assertion — the E2E parity suite can now verify alarm-condition registration shape in addition to folder/variable shape. Tests (4 new GenericDriverNodeManagerTests): Alarm_events_are_routed_to_the_sink_registered_for_the_matching_source_node_id — 2 alarms registered (Tank.HiHi + Heater.OverTemp), driver raises an event for Tank.HiHi, the Tank.HiHi sink captures the payload, the Heater.OverTemp sink does not (tag-scoped fan-out, not broadcast); Non_alarm_variables_do_not_register_sinks — plain Tank.Level in the same discover is not in TrackedAlarmSources; Unknown_source_node_id_is_dropped_silently — a transition for Unknown.Source doesn't reach any sink + no exception; Dispose_unsubscribes_from_OnAlarmEvent — post-dispose, a transition for a previously-registered tag is no-op because the forwarder detached. InternalsVisibleTo('ZB.MOM.WW.OtOpcUa.Core.Tests') added to Core csproj so TrackedAlarmSources internal property is visible to the test. Full solution: 0 errors, 152 unit tests pass (8 Core + 14 Proxy + 14 Admin + 24 Configuration + 6 Shared + 84 Galaxy.Host + 2 Server). PR 16 will implement the concrete OPC UA address-space builder that materializes AlarmConditionState from this contract.

Phase 2 PR 14 — alarm subsystem wire-up. Per IsAlarm=true attribute (PR 9 added the discovery flag), GalaxyAlarmTracker in Backend/Alarms/ advises the four Galaxy alarm-state attributes: .InAlarm (boolean alarm active), .Priority (int severity), .DescAttrName (human-readable description), .Acked (boolean acknowledged). Runs the OPC UA Part 9 alarm lifecycle state machine simplified for the Galaxy AlarmExtension model and raises AlarmTransition events on transitions operators must react to — Active (InAlarm false→true, default Unacknowledged), Acknowledged (Acked false→true while InAlarm still true), Inactive (InAlarm true→false). MxAccessGalaxyBackend instantiates the tracker in its constructor with delegate-based subscribe/unsubscribe/write pointers to MxAccessClient, hooks TransitionRaised to forward each transition through the existing OnAlarmEvent IPC event that PR 4 ConnectionSink wires into MessageKind.AlarmEvent frames — no new contract messages required since GalaxyAlarmEvent already exists in Shared.Contracts. Field mapping: EventId = fresh Guid.ToString('N') per transition, ObjectTagName = alarm attribute full reference, AlarmName = alarm attribute full reference, Severity = tracked Priority, StateTransition = 'Active'|'Acknowledged'|'Inactive', Message = DescAttrName or tag fallback, UtcUnixMs = transition time. DiscoverAsync caches every IsAlarm=true attribute's full reference (tag.attribute) into _discoveredAlarmTags (ConcurrentBag cleared-then-filled on every re-Discover to track Galaxy redeploys). SubscribeAlarmsAsync iterates the cache and advises each via GalaxyAlarmTracker.TrackAsync; best-effort per-alarm — a subscribe failure on one alarm doesn't abort the whole call since operators prefer partial alarm coverage to none. Tracker is internally idempotent on repeat Track calls (second invocation for same alarm tag is a no-op; already-subscribed check short-circuits before the 4 MXAccess sub calls). Subscribe-failure rollback inside TrackAsync removes the alarm state + unadvises any of the 4 that did succeed so a partial advise can't leak a phantom tracking entry. AcknowledgeAlarmAsync routes to tracker.AcknowledgeAsync which writes the operator comment to <tag>.AckMsg via MxAccessClient.WriteAsync — writes use the existing MXAccess OnWriteComplete TCS-by-handle path (PR 4 Medium 4) so a runtime-refused ack bubbles up as Success=false rather than false-positive. State-machine quirks preserved from v1: (1) initial Acked=true on subscribe does NOT fire Acknowledged (alarm at rest, pre-acknowledged — default state is Acked=true so the first subscribe callback is a no-op transition), (2) Acked false→true only fires Acknowledged when InAlarm is currently true (acking a latched-inactive alarm is not a user-visible transition), (3) Active transition clears the Acked flag in-state so the next Acked callback correctly fires Acknowledged (v1 had this buried in the ConditionState logic; we track it on the AlarmState struct directly). Priority value handled as int/short/long via type pattern match with int.MaxValue guard — Galaxy attribute category returns varying CLR types (Int32 is canonical but some older templates use Int16), and a long overflow cast to int would silently corrupt the severity. Dispose cascade in MxAccessGalaxyBackend.Dispose: alarm-tracker unsubscribe→dispose, probe-manager unsubscribe→dispose, mx.ConnectionStateChanged detach, historian dispose — same discipline PR 6 / PR 8 / PR 13 established so dangling invocation-list refs don't survive a backend recycle. #pragma warning disable CS0067 around OnAlarmEvent removed since the event is now raised. Tests (9 new, GalaxyAlarmTrackerTests): four-attribute subscribe per alarm, idempotent repeat-track, InAlarm false→true fires Active with Priority + Desc, InAlarm true→false fires Inactive, Acked false→true while InAlarm fires Acknowledged, Acked transition while InAlarm=false does not fire, AckMsg write path carries the comment, snapshot reports latest four fields, foreign probe callback for a non-tracked tag is silently dropped. Full Galaxy.Host.Tests Unit suite 84 pass / 0 fail (9 new alarm + 12 PR 13 probe + 21 PR 12 quality + 42 pre-existing). Galaxy.Host builds clean (0/0). Branches off phase-2-pr13-runtime-probe so the MxAccessGalaxyBackend constructor/Dispose chain gets the probe-manager + alarm-tracker wire-up in a coherent order; fast-forwards if PR 13 merges first.

Phase 2 PR 11 — HistoryReadEvents IPC (alarm history). New Shared.Contracts messages HistoryReadEventsRequest/Response + GalaxyHistoricalEvent DTO (MessageKind 0x66/0x67). IGalaxyBackend gains HistoryReadEventsAsync, Stub/DbBacked return canonical pending error, MxAccessGalaxyBackend delegates to _historian.ReadEventsAsync (ported in PR 5) and maps HistorianEventDto → GalaxyHistoricalEvent — Guid.ToString() for EventId wire shape, DateTime → Unix ms for both EventTime (when the event fired in the process) and ReceivedTime (when the Historian persisted it), DisplayText + Severity pass through. SourceName is string? — null means 'all sources' (passed straight through to HistorianDataSource.ReadEventsAsync which adds the AddEventFilter('Source', Equal, ...) only when non-null). Distinct from the live GalaxyAlarmEvent type because historical rows carry both timestamps and lack StateTransition (Historian logs instantaneous events, not the OPC UA Part 9 alarm lifecycle; translating to OPC UA event lifecycle is the alarm-subsystem's job). Guards: null historian → Historian-disabled error; SDK exception → Success=false with message chained. Tests (3 new): disabled-error when historian null, maps HistorianEventDto with full field set (Id/Source/EventTime/ReceivedTime/DisplayText/Severity=900) to GalaxyHistoricalEvent, null SourceName passes through unchanged (verifies the 'all sources' contract). Galaxy.Host.Tests Unit suite 34 pass / 0 fail. Galaxy.Host builds clean. Branches off phase-2-pr10-history-attime since both extend the MessageKind enum; fast-forwards if PR 10 merges first.

ZB.MOM.WW.OtOpcUa.Driver.Modbus

Phase 3 PR 24 — Modbus PLC data type extensions. Extends ModbusDataType beyond the textbook Int16/UInt16/Int32/UInt32/Float32 set with Int64/UInt64/Float64 (4-register types), BitInRegister (single bit within a holding register, BitIndex 0-15 LSB-first), and String (ASCII packed 2 chars per register with StringLength-driven sizing). Adds ModbusByteOrder enum on ModbusTagDefinition covering the two word-orderings that matter in the real PLC population: BigEndian (ABCD — Modbus TCP standard, Schneider PLCs that follow it strictly) and WordSwap (CDAB — Siemens S7 family, several Allen-Bradley series, some Modicon families). NormalizeWordOrder helper reverses word pairs in-place for 32-bit values and reverses all four words for 64-bit values (keeps bytes big-endian within each register, which is universal; swaps only the word positions). Internal codec surface switched from (bytes, ModbusDataType) pairs to (bytes, ModbusTagDefinition) because the tag carries the ByteOrder + BitIndex + StringLength context the codec needs; RegisterCount similarly takes the tag so strings can compute ceil(StringLength/2). DriverDataType mapping in MapDataType extended to cover the new logical types — Int64/UInt64 widen to Int32 (PR 25 follow-up: extend DriverDataType enum with Int64 to avoid precision loss), Float64 maps to DriverDataType.Float64, String maps to DriverDataType.String, BitInRegister surfaces as Boolean, all other mappings preserved. BitInRegister writes throw a deliberate InvalidOperationException with a 'read-modify-write' hint — to atomically flip a single bit the driver needs to FC03 the register, OR/AND in the bit, then FC06 it back; that's a separate PR because the bit-modify atomicity story needs a per-register mutex and optional compare-and-write semantics. Everything else (decoder paths for both byte orders, Int64/UInt64/Float64 encode + decode, bit-index extraction across both register halves, String nul-truncation on decode, String nul-padding on encode) ships here. Tests (21 new ModbusDataTypeTests): RegisterCount_returns_correct_register_count_per_type theory (10 rows covering every numeric type); RegisterCount_for_String_rounds_up_to_register_pair theory (5 rows including the 0-char edge case that returns 0 registers); Int32_BigEndian_decodes_ABCD_layout + Int32_WordSwap_decodes_CDAB_layout + Float32_WordSwap_encode_decode_roundtrips (covers the two most-common 32-bit orderings); Int64_BigEndian_roundtrips + UInt64_WordSwap_reverses_four_words (word-swap on 64-bit reverses the four-word layout explicitly, with the test computing the expected wire shape by hand rather than trusting the implementation) + Float64_roundtrips_under_word_swap (3.14159265358979 survives the round-trip with 1e-12 tolerance); BitInRegister_extracts_bit_at_index theory (6 rows including LSB, MSB, and arbitrary bits in a multi-bit mask); BitInRegister_write_is_not_supported_in_PR24 (asserts the exception message steers the reader to the 'read-modify-write' follow-up); String_decodes_ASCII_packed_two_chars_per_register (decodes 'HELLO!' from 3 packed registers with the 'HELLO!'u8 test-only UTF-8 literal which happens to equal the ASCII bytes for this ASCII input); String_decode_truncates_at_first_nul ('Hi' padded with nuls reads back as 'Hi'); String_encode_nul_pads_remaining_bytes (short input writes remaining bytes as 0). Full solution: 0 errors, 217 unit + integration tests pass (22 + 30 new Modbus = 52 Modbus total, 165 pre-existing). ModbusDriver capability footprint now matches the most common industrial PLC workloads — Siemens S7 + Allen-Bradley + Modicon all supported via ByteOrder config without driver forks.

ZB.MOM.WW.OtOpcUa.Server

Phase 3 PR 31 — Live-LDAP integration test + Active Directory compatibility. Closes LMX follow-up #4 with 6 live-bind tests in Server.Tests/LdapUserAuthenticatorLiveTests.cs against the dev GLAuth instance at localhost:3893 (skipped cleanly when unreachable via Assert.Skip + a clear SkipReason — matches the GalaxyRepositoryLiveSmokeTests pattern). Coverage: valid credentials bind + surface DisplayName; wrong password fails; unknown user fails; empty credentials fail pre-flight without touching the directory; writeop user's memberOf maps through GroupToRole to WriteOperate (the exact string WriteAuthzPolicy.IsAllowed expects); admin user surfaces all four mapped roles (WriteOperate + WriteTune + WriteConfigure + AlarmAck) proving memberOf parsing doesn't stop after the first match. While wiring this up, the authenticator's hard-coded user-lookup filter 'uid=<name>' didn't match GLAuth (which keys users by cn and doesn't populate uid) — AND it doesn't match Active Directory either, which uses sAMAccountName. Added UserNameAttribute to LdapOptions (default 'uid' for RFC 2307 backcompat) so deployments override to 'cn' / 'sAMAccountName' / 'userPrincipalName' as the directory requires; authenticator filter now interpolates the configured attribute. The default stays 'uid' so existing test fixtures and OpenLDAP installs keep working without a config change — a regression guard in LdapUserAuthenticatorAdCompatTests.LdapOptions_default_UserNameAttribute_is_uid_for_rfc2307_compat pins this so a future 'helpful' default change can't silently break anyone.
