The SDK fires OnTimedUnshelve with the node manager's system context (no
session, no user identity) when a TimedShelve duration expires. Routing
through the shared HandleAlarmCommand hit the AlarmAck gate and returned
BadUserAccessDenied, leaving the alarm permanently shelved.
Replace the delegated HandleAlarmCommand call with an inline lambda that
bypasses the client gate, extracts the AlarmId the same way, and routes an
Unshelve command so the engine clears its shelve state. The manual-client
Unshelve path via OnShelve(shelving:false) remains gated.
Update the AlarmCommandRouterTests OnTimedUnshelve test to use a real
system context (no UserIdentity) — reproducing the actual SDK invocation
path — and assert Good, AlarmId, Operation==Unshelve, User==empty.
Add a doc note to AlarmCommand.Operation that Enable/Disable are in the
vocabulary but not yet wired at the node-manager seam.
Wire the materialised AlarmConditionState method handlers so a client calling
Acknowledge/Confirm/Shelve/AddComment is gated on the AlarmAck data-plane role
and, when allowed, routed back to the scripted-alarm engine via a new
`alarm-commands` DistributedPubSub topic.
- Commons: new AlarmCommand DTO (AlarmId/Operation/User/Comment/UnshelveAtUtc).
- ScriptedAlarmHostActor: add AlarmCommandsTopic const.
- OtOpcUaNodeManager: settable AlarmCommandRouter + wire OnAcknowledge/OnConfirm/
OnAddComment/OnShelve/OnTimedUnshelve. Each resolves the principal off
ISessionOperationContext.UserIdentity as RoleCarryingUserIdentity, fails closed
(BadUserAccessDenied) when the AlarmAck role is absent or no identity, else maps
+ routes an AlarmCommand and returns Good. OnShelve discriminates OneShotShelve/
TimedShelve/Unshelve from the SDK flags; TimedShelve expiry = UtcNow + ms.
No Akka/IActorRef handle — only the Action<AlarmCommand> delegate. T20 de-dup
note left; WriteAlarmCondition untouched.
- OpcUaServer.Security: OpcUaDataPlaneRoles.AlarmAck shared const (the role was a
bare string everywhere; introduced one symbol for the gate + tests).
- OtOpcUaSdkServer: SetAlarmCommandRouter pass-through.
- Host: boot wiring publishes each command via mediator.Tell(Publish(...)) using a
lazy ActorSystem accessor (mirrors DpsScriptLogPublisher).
- Tests: 11 new gate + mapping tests (OpcUaServer.Tests 88->99, all green).
Code-review follow-up to T17: copy the roles into a fresh array at construction so a
caller mutating the source list cannot retroactively alter a session's granted roles,
and so the T18 ack gate's per-invocation .Contains(...) runs over a known-small frozen
array.
Stop discarding the authenticator's resolved roles during impersonation.
HandleImpersonation now sets args.Identity to a RoleCarryingUserIdentity
(: UserIdentity) that carries result.Roles, so a downstream method handler
can read them off context.UserIdentity for the inbound AlarmAck gate (T18).
Verified via the decompiled SDK (1.5.378.106) that the instance we assign to
ImpersonateEventArgs.Identity is stored by reference onto Session.Identity /
EffectiveIdentity and surfaced unchanged on OperationContext.UserIdentity --
the custom subclass survives the round-trip. No auth-decision logic changes.
Default HistorizeToAveva/Retain/Enabled to the entity defaults (true) when a
field is absent/null/non-boolean so a partial blob decodes identically to the
composer's view of a default-constructed ScriptedAlarm (byte-parity), and only
call GetBoolean for a genuine true/false token. Add direct ExtractAlarmDependencyRefs
unit tests (overlap dedup + reserved {{equip}} exclusion).
Concrete ITagUpstreamSource the scripted-alarm host actor pushes
DependencyValueChanged values into and ScriptedAlarmEngine reads/subscribes
from. Thread-safe: ConcurrentDictionary value cache + per-path ImmutableList
observer lists with atomic add/remove and capture-then-invoke fan-out.
ReadTag of an unknown path returns a Bad-quality (0x80000000) snapshot stamped
via the injected clock. Adds the Core.ScriptedAlarms project reference Runtime
needs to see the interface.
ScriptId is now system-generated on create (mirrors EquipmentId's EQ-{12 hex}
convention, never operator-supplied) and shown read-only when editing. Language
is always CSharp, so the single-option dropdown is removed entirely and set on
save.
Monaco's word definition splits on '.', so accepting a full tag path while a
partial path was typed (e.g. "X.Protected") duplicated the prefix
(-> "X.X.ProtectedValue"). Tag-path items now replace the whole literal
content from the opening quote to the caret.
The suggest/hover popups were offset far from the caret because the theme's
.rise entrance animation leaves a CSS transform on an ancestor, which becomes
the containing block for the position:fixed overflow widgets. Render them in a
body-level overflowWidgetsDomNode so they stay viewport-correct at the caret.
