Materialize each native alarm ONCE at the raw tag (ConditionId = RawPath, Raw
realm); wire the single condition as an SDK event notifier of each referencing
equipment's UNS folder so one ReportEvent fans to every root without
re-reporting per root (which would break Server-object dedup + Part 9 ack
correlation).
- New sink method WireAlarmNotifiers(alarmNodeId, alarmRealm,
notifierFolderNodeIds, notifierFolderRealm) on IOpcUaAddressSpaceSink,
forwarded through DeferredAddressSpaceSink + SdkAddressSpaceSink +
NullOpcUaAddressSpaceSink (the forwarding-trap guard); auto-covered by the
DeferredSinkForwardingReflectionTests realm + forwarding guards + a
hand-written forward test.
- OtOpcUaNodeManager: the normative AddNotifier(isInverse) pair + idempotent
EnsureFolderIsEventNotifier per equipment folder; tracked per condition in
_alarmNotifierWiring. Teardown symmetry: RemoveNotifier(bidirectional:true) on
RebuildAddressSpace, RemoveAlarmConditionNode, and RemoveEquipmentSubtree so no
inverse-notifier entry leaks across redeploys.
- AddressSpaceApplier.MaterialiseRawSubtree wires notifiers for each native alarm
tag, resolving its ReferencingEquipmentPaths (Area/Line/Equipment) to the
EquipmentId folder NodeIds via BuildEquipmentIdByFolderPath.
- AlarmTransitionEvent gains ReferencingEquipmentPaths (empty default); /alerts
renders the referencing-equipment list as display metadata.
- Un-skipped + rewrote the native-alarm dark tests
(DriverHostActorNativeAlarmTests x6, DriverHostActorNativeAlarmAckRoutingTests
x1) for the v3 raw-condition model; new NodeManagerMultiNotifierAlarmTests
proves multi-notifier wiring + teardown symmetry (no leaked duplicates after a
re-trip) + applier wiring test.

Final F15 batch wires up the SignalR-backed live pages, ports the bulk
equipment importer, and progressively enhances the Script source editor
with Monaco.
Message contracts:
- Commons.Messages.Alerts.AlarmTransitionEvent — fires on every alarm
state transition; published on the `alerts` DPS topic by future
ScriptedAlarmActor (F9) emits.
- Commons.Messages.Logging.ScriptLogEntry — one log line emitted by a
hosted script; published on the `script-logs` DPS topic by future
VirtualTagActor (F8) + ScriptedAlarmActor (F9) emits.
(Folder named "Logging" to dodge .gitignore's "logs/" rule.)
SignalR plumbing:
- AlertHub gains MethodName + bridge actor (AlertSignalRBridge)
- ScriptLogHub introduced; ScriptLogSignalRBridge follows the same
DPS-subscribe → IHubContext fan-out pattern as FleetStatusSignalRBridge
- WithOtOpcUaSignalRBridges now spawns all three bridges
- MapOtOpcUaHubs maps /hubs/script-log alongside the existing hubs
Pages:
- /alerts live alarm tail, 200-row capacity
- /script-log live script-log tail with level + script
filter, 500-row capacity
- /clusters/{id}/equipment/import — CSV bulk Equipment add with preview
(Name/MachineCode/UnsLineId/Driver +
optional ZTag/SAPID/Manufacturer/Model;
skips rows whose MachineCode already
exists in the fleet)
- ScriptEdit progressively enhanced with Monaco editor via JSInterop —
the textarea remains Blazor's source of truth and Monaco syncs into it
on every keystroke so @bind keeps working; falls back gracefully if
the CDN is unreachable.
MainLayout nav gains a "Live" section (Deployments, Alerts, Alarms
historian) and a "Scripts" link under Scripting. ClusterEquipment
surfaces the new Import CSV button.
Tally: F15 ships ~42 razor pages + 3 SignalR hubs + 3 bridge actors.
Microsoft.AspNetCore.SignalR.Client added (was already in central PM).
All 104 v2 tests remain green.
