From 70d7166a39bfefcae420f3ba61ecad4f93a3bc88 Mon Sep 17 00:00:00 2001 From: Joseph Doherty Date: Mon, 18 May 2026 04:38:46 -0400 Subject: [PATCH 1/4] =?UTF-8?q?test(server):=20harden=20deferred=20authz?= =?UTF-8?q?=20gates=20=E2=80=94=20task=20#12=20Browse/Subscribe/Call/Alarm?= =?UTF-8?q?Ack?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add DeferredGateHardeningTests (28 unit tests) covering the Phase 6.2 compliance-checklist gaps left by the per-gate unit suites that shipped with the gate implementations: - Lax-mode fall-through for CreateMonitoredItems and Call gates (null identity and identity-without-LDAP-groups both skip denial in lax mode, consistent with BrowseGatingTests.Lax_mode_null_identity) - Flag isolation: Subscribe-only grant does NOT imply Read; Read-only grant does NOT imply Subscribe; HistoryRead-only grant does NOT imply Read and vice versa (Phase 6.2 compliance: "HistoryRead uses its own flag") - Alarm-bit isolation: AlarmAcknowledge alone does not grant AlarmConfirm or AlarmShelve; Browse alone does not grant AlarmAcknowledge - AlarmShelve falls through to OpcUaOperation.Call in MapCallOperation (documents the ShelvedStateMachine per-instance NodeId limitation noted in the implementation, with the follow-up path: MethodCall grant covers it) - Complete OpcUaOperation→NodePermissions mapping coverage for all deferred operations (Browse, CreateMonitoredItems, TransferSubscriptions, Call, AlarmAcknowledge, AlarmConfirm, AlarmShelve) — both positive and wrong-bit negative cases - Multi-group union for deferred gates (grp-browse ∪ grp-ack gives both Browse and AlarmAcknowledge without leaking Read or Call) Build: 0 errors on Server.csproj (verified against main repo build which carries the gRPC-generated Galaxy driver artifacts the isolated worktree lacks — that pre-existing gap is unrelated to these changes). Test count: 247 → 275 (+28 unit, 0 failures).

The plan's Stream G wiring of these methods to OPC UA `MethodCall` dispatch on the condition nodes (so OPC UA client method calls reach the engine with the authenticated principal) is noted in the e2e smoke doc as "not yet wired through `DriverNodeManager.MethodCall` dispatch."

That path changed: the production implementation uses `Driver.Historian.Wonderware.Client` (`WonderwareHistorianClient.WriteBatchAsync`) over a named-pipe sidecar, not Galaxy.Host. There is no separate `docs/v2/historian-alarm-api.md` artifact documenting the SDK entry point as the plan called for; the implementation detail is in `WonderwareHistorianClient.cs` inline. | +| D.3 — `Driver.Galaxy.Shared` contract additions (`HistorianAlarmEventRequest` / `Response` / `ConnectivityStatusNotification`) | **Changed** | The plan routed alarm writes through Galaxy.Host IPC. The shipped implementation uses `Driver.Historian.Wonderware.Client` (a standalone sidecar project) instead. `HistorianAlarmEventRequest` / `HistorianAlarmEventResponse` as named protos never shipped; the equivalent contract is the `AlarmHistorianEventDto` / `WriteAlarmEventsRequest` / `WriteAlarmEventsReply` MessagePack DTOs in `Driver.Historian.Wonderware.Client/Ipc/`. Galaxy.Host still exists as the mxaccessgw entry point but does not carry historian writes. | +| D.4 — `Driver.Galaxy.Host` handler for alarm writes | **Changed** | Not shipped via Galaxy.Host. The sidecar (`Driver.Historian.Wonderware.Client`) is the production path. `IAlarmHistorianWriter` is implemented by `WonderwareHistorianClient`, not by a Galaxy.Host frame handler. | +| D.5 — Drain worker in main server (poll SQLite queue, batch 100 events, exponential backoff) | **Done** | `SqliteStoreAndForwardSink.StartDrainLoop`; backoff ladder 1s → 2s → 5s → 15s → 60s; `Phase7Composer.ResolveHistorianSink` starts it with a 2-second drain cadence | +| D.6 — Per-alarm `HistorizeToAveva` toggle; `AlarmHistorizationPolicy` per source | **Done** | `ScriptedAlarm.HistorizeToAveva` column (default `true`); `Phase7EngineComposer.RouteToHistorianAsync` checks it; Galaxy defaults `false` | +| D.7 — `/alarms/historian` diagnostics view in Admin (queue depth, drain rate, last error, retry dead-lettered) | **Done** | `AlarmsHistorian.razor`; `HistorianDiagnosticsService.cs` | +| D.8 — Tests | **Done** | `SqliteStoreAndForwardSinkTests.cs`; `Phase7ComposerWriterSelectionTests.cs` covers historian-writer resolution | + +Shipped as PR #182 (14 tests).

There is no separate `/virtual-tags` tab UI — virtual tags are managed through the script service alone; no VirtualTag list/edit form exists in the Admin UI. The per-tag fields (`EquipmentId`, `DataType`, `ChangeTriggered`, `TimerIntervalMs`, `Historize`) are accessible via the `VirtualTagService` backend but have no corresponding UI form. | +| F.3 — `/scripted-alarms` tab (alarm type, severity, message template, `HistorizeToAveva`, detail page with shelve/ack state read-only) | **Partial** | No dedicated scripted-alarms tab razor page exists (confirmed by Glob + Grep searches). Scripted alarm CRUD (`ScriptedAlarmService`) exists as a service but has no Admin UI page. | +| F.4 — Test harness (modal, synthetic inputs, output + logger display) | **Partial** | `ScriptTestHarnessService.cs` is complete and tested. `ScriptsTab.razor` calls `Harness.RunVirtualTagAsync` with zero-value synthetic inputs derived from the extractor. A full interactive input-form modal was not shipped — the harness zeroes all inputs automatically rather than prompting the operator per-tag. | +| F.5 — Script log viewer (SignalR tail of `scripts-*.log` filtered by `ScriptName`, load-more) | **Not started** | No SignalR stream of the scripts log is wired in the Admin UI.
