Goal + +Make **HistorianGateway** the historian read/write backend for the **OtOpcUa** OPC UA server, +serving two distinct use cases: + +1. **Read of historic values for mxaccessgw-served (Galaxy) tags & alarms.** Galaxy tags are + already historized by AVEVA's own IOServer/AppServer pipeline; OtOpcUa serves their history + to OPC UA `HistoryRead` clients by reading them back through the gateway. +2. **Full read/write historian backend for non-mxaccessgw tags & alarms** (Modbus / S7 / AB / + TwinCAT / FOCAS / scripted-alarm sources). These are *not* historized by AVEVA, so OtOpcUa + **records** their live value changes and alarm events into the historian through the gateway, + then reads them back through the same path. + +The vehicle, per decision, is a **dedicated .NET gRPC client library** for the gateway — +`ZB.MOM.WW.HistorianGateway.Client` — built "similar to the mxaccessgw client" +(`ZB.MOM.WW.MxGateway.Client`), which OtOpcUa consumes as a Gitea-feed package. + +## 2.

What gets added to HistorianGateway + +1. **`ZB.MOM.WW.HistorianGateway.Client`** (NEW, `clients/dotnet/`). Clones the `MxGatewayClient` + pattern: `HistorianGatewayClient.Create(options)` owning a `GrpcChannel` over a + `SocketsHttpHandler` (TLS, connect timeout), Polly resilience pipeline (retry transient codes + only), `histgw__` bearer key attached in the `authorization` metadata header, + typed exception hierarchy, and wrappers for all five services (unary → `Task`, streaming → + `IAsyncEnumerable`). Packable NuGet, references the Contracts project. +2. **Make `ZB.MOM.WW.HistorianGateway.Contracts` packable + publish to the Gitea feed** (it has no + packaging props today). Mirrors `ZB.MOM.WW.MxGateway.Contracts @ 0.1.x`. This is what lets the + Client and OtOpcUa consume generated `historian_gateway.v1` types as a package. +3. **SQL `ReadEvents` source-name filter** (small enhancement, coordinated with the in-flight + `feat/sql-readevents` branch). The SQL event-read path is currently time-range-only + (per-property filter → `Unimplemented`); add `Source_Object` filtering so OtOpcUa's + `ReadEventsAsync(sourceName, …)` is server-filtered rather than full-window + client-side filter. +4. **Optional smoke CLI** (`…Client.Cli`) mirroring `mxgw` cli — manual live checks. +5. **Deployment/config prerequisites** (no code): the gateway OtOpcUa points at must run with + `RuntimeDb:Enabled=true` (WriteLiveValues) **and** `RuntimeDb:EventReadsEnabled=true` (alarm + reads). Provision an API key carrying `historian:read`, `historian:write`, + `historian:tags:write`. + +## 6.

T3/T14/T17 encode this; T21 documents it. +3. **Alarm-history reads depend on the gateway's SQL event path.** `ReadEventsAsync` requires the gateway deployed with `RuntimeDb:EventReadsEnabled=true`; the **source-name server filter** is delivered by the gateway-client plan (§5.3) — until it lands, T11 filters client-side and must not assume server filtering. +4. **`WriteLiveValues` requires gateway `RuntimeDb:Enabled=true` AND an `EnsureTags`-provisioned tag.** The provisioning hook (T15) must have run for a tag before the recorder's writes (T17) land — provisioning is fire-and-forget, so the first few values for a brand-new historized tag may be rejected until `EnsureTags` completes; the outbox retains + retries them (no loss).

WriteBatchAsync short-circuits remaining events to RetryPlease once cancellation is requested, and SendOneAsync catches OperationCanceledException (when the token is cancelled) -> RetryPlease, so in-flight events stay queued instead of being permanently dropped. I-2: FasterLogHistorizationOutbox.Dispose now guards the awaited periodic loop with a broad catch (Exception) after the OperationCanceledException catch, so a non-Faster teardown fault (e.g. ObjectDisposedException) can never escape Dispose. M-1: GatewayTagProvisioner skips the empty EnsureTags round-trip when every request is non-historizable (early return). M-2: GatewayTagProvisioner handles plain shutdown cancellation quietly (Debug, not Warning), counting the unsent batch as Failed, never throwing. M-3/M-4: Added remove-last-entry (TailAddress truncation branch) and FIFO implicit-ack (RemoveAsync acks up to and including the target) durability tests, both reopen-and-survive. M-5: Clarifying comment in RecoverState on the transient over-capacity rebuild after a crash between append-commit and drop-truncation-commit.

Registers interest with the per-node DependencyMuxActor for the historized refs and taps the VirtualTagActor.DependencyValueChanged values the mux fans: coerce to numeric -> append to the durable IHistorizationOutbox (crash boundary) -> off-thread drain writes batches through IHistorianValueWriter and acks (FIFO-truncates) on success, backing off (exponential, capped) on failure. Non-numeric values are dropped + metered (SQL analog path is numeric-only). - New seam IHistorianValueWriter + HistorizationValue in Core.Abstractions so Runtime stays free of the gRPC driver. - GatewayHistorianValueWriter (driver) adapts IHistorianGatewayClient. WriteLiveValues: HistorizationValue -> HistorianLiveValue proto, WriteAck Success||Queued -> true; non-throwing (errors -> false for retry). - Drain runs via PipeTo(Self) so the mailbox never blocks on the gateway write; appends awaited on the actor thread to stay serialized.

A canceled append during shutdown returns quietly; any other exception increments a new _outboxAppendFailures counter, logs a Warning (exception type name only), and drops the value without recording it or nudging the drain. The counter is surfaced on RecorderStatus (new OutboxAppendFailures field).

M-3: Capture Sender before the await in the GetStatus handler, then Tell the reply. M-4: Add Retry_after_writer_failure_eventually_acks proving the retry -> success -> ack path; FakeValueWriter gains a FailFirstN option + CallCount (Succeed behaviour unchanged).

retire Wonderware from docs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit HistorianGateway is now the sole historian backend (read + alarm SendEvent + continuous WriteLiveValues). Document the final state and retire the Wonderware sidecar from the docs/config/labels: - CLAUDE.md: rewrite the Historian section — ServerHistorian / ContinuousHistorization / AlarmHistorian config keys, the IHistorianProvisioning EnsureTags hook, the GatewayAlarmHistorianWriter SendEvent path + ReadEvents dependency on gateway RuntimeDb:EventReadsEnabled=true, gateway-side prerequisites (RuntimeDb flags + historian:read/write/tags:write scopes), migration note, and two KNOWN-LIMITATION callouts (live-validation gate + empty historized-ref-set recorder follow-on). - appsettings.json: fix the stale ServerHistorian block (Host/Port/SharedSecret/ ServerCertThumbprint -> Endpoint/ApiKey/UseTls/AllowUntrustedServerCertificate/ CaCertificatePath/CallTimeout, keep MaxTieClusterOverfetch); add a disabled ContinuousHistorization block; prune the orphaned Wonderware keys from AlarmHistorian (keep the SQLite knobs). ApiKey env-supplied via ServerHistorian__ApiKey (commented; valid strict JSON via _comment keys). - README.md + docs (Historian.md, AlarmHistorian.md, Configuration.md, ServiceHosting.md, DriverLifecycle.md, drivers/README.md, Uns.md, VirtualTags.md, AlarmTracking.md, Client.UI.md, README.md, TestConnectProbes.md): retire the Wonderware historian backend from current-backend descriptions; fix the stale ServerHistorian/AlarmHistorian config tables (now gateway shape); convert drivers/Historian.Wonderware.md to a retired stub pointing at the gateway. - Source/UI labels (descriptive text only, no behavior change): OtOpcUaServerHostedService.cs, HistoryPaging.cs, OtOpcUaSdkServer.cs, HistorianAdapterActor.cs, VirtualTagModal.razor, ScriptedAlarmModal.razor, AlarmsHistorian.razor now name the HistorianGateway backend. Build clean (0 errors); AdminUI.Tests green (514 passed).

This feeds it the currently-historized tag refs on every address-space deploy/redeploy so its DependencyMuxActor interest converges to exactly the historized set (the same refs the EnsureTags provisioning hook resolves: override-or-FullName). Design — delta convergence (the plan is a pure DIFF): - New seam IHistorizedTagSubscriptionSink (Core.Abstractions/Historian) with a Null no-op singleton, mirroring how IHistorianProvisioning decouples the T15 hook. AddressSpaceApplier gains a DEFAULTED ctor param (Null sink) so all ~80 existing call sites + the production site compile unchanged. - Apply() only ever sees a plan diff (an incremental/surgical apply carries a delta, not the full set), so the applier feeds an add/remove DELTA computed from AddedEquipmentTags / RemovedEquipmentTags / ChangedEquipmentTags. The recorder keeps the full set and re-registers it. The feed is a single non-blocking Tell behind the sink, wrapped in try/catch so a faulting feed never blocks or breaks a deploy (same discipline as the provisioning hook). - Recorder.UpdateHistorizedRefs(added, removed) converges the tracked set, then — only when it actually changed — sends ONE RegisterInterest with the full set (the mux's RegisterInterest is a full-REPLACE) or one UnregisterInterest when it drains to empty (the mux has no per-ref unregister). An unchanged delta is a no-op (no mux churn). - DI: the recorder is now spawned BEFORE the applier so the adapter (ActorHistorizedTagSubscriptionSink) can wrap its IActorRef; the Null sink is used when continuous historization is off/unwired. Tests: recorder convergence (add-from-empty, add+remove converge, idempotent, drain-to-empty unregisters); applier feeds resolved added refs, removed+renamed deltas, and survives a throwing sink. Build clean (0 warnings on touched projects); Runtime/OpcUaServer/Gateway/AdminUI suites green.

AlarmEventMapper now leaves HistorianEvent.Id unset (the historian assigns event identity) and preserves the alarm's id as an 'AlarmId' property. With this, the live alarm send acks. Also harden the env-gated live tests against two gateway/historian-side limitations surfaced during validation (neither an OtOpcUa defect): the write readback uses a timezone-tolerant window (an explicit-timestamp WriteLiveValues lands offset by the deployment's local-vs-UTC delta — reproducible via raw grpcurl; OtOpcUa sends correct UTC), and the alarm ReadEvents readback skips with a clear reason when the historian's server-gated event reads (C2, won't-fix) return nothing. Read + write-persist + alarm-send are all live-validated green; the alarm send-ack is split into its own test.

The gateway's `SqlEventReader` filters +`WHERE Source_Object = @source`, so a source-filtered `ReadEvents` of a just-sent event returns 0. + +**What works (so this is narrow, not "C2 won't-fix"):** +- Time-only `ReadEvents` (no source filter) returns events (50 in a 2-day window during validation). +- Source-filtered `ReadEvents` for a **real Galaxy event source** (`TableAlarms_006`) returns its + history (`System.Deploy`/`Undeploy`/`Alarm.Set`, each with `source_name` populated). So the SQL + reader + source filter are functional; only **ad-hoc SendEvents lack a `Source_Object`.** +- ⇒ **Reading existing Galaxy alarm/event history by source already works** (the mxaccessgw read use + case). Only round-tripping OtOpcUa's *own* sends by source is blocked. + +**Investigation (gateway repo):** +- Read the v8 event-send path: `RegisterCmEventTag` + the `ConnectionType=Event` send (CM_EVENT). Find + where the event's source/tag is set on the wire payload and whether the historian maps any send-side + field → the `Events.Source_Object` column. Start at the gateway `SendEvent` service + the vendored + `AVEVA.Historian.Client` event session (`HistorianEventSession`), and the + `event-session-reuse-spike` notes in `../histsdk/docs/reverse-engineering/`. +- Determine whether the historian's CM_EVENT API even *allows* setting a `Source_Object` for an event + not raised by a Galaxy object. If the source must be a registered event-tag/source name, decide how + OtOpcUa's `EquipmentPath` should map to it. + +**Proposed fix (one of):** +1. If the send payload has a source/tag field that maps to `Source_Object`: populate it from the event's + `source_name` in the gateway `SendEvent` handler. (Preferred — makes write-back-by-source work.) +2. If the historian cannot carry a source for ad-hoc events: document it, and have the gateway's + `SqlEventReader` optionally match the source in a fallback column the send *does* populate (if any), + or expose a "read all events in window, filter client-side" mode. Update OtOpcUa's + `GatewayHistorianDataSource.ReadEventsAsync` defensive client-side source filter accordingly (it + currently drops events whose mapped `SourceName` ≠ requested source — which would also drop + source-less sends even if the server returned them). + +**Acceptance:** an OtOpcUa `SendEvent(source=X)` is readable back via `ReadEvents(source=X)` within the +window. Then **un-skip** `Alarm_SendEvent_then_ReadEvents` in +`tests/Drivers/.../Live/GatewayLiveIntegrationTests.cs` (it currently `Assert.Skip`s on a 0-result with +the accurate reason). + +### FU-2 — `WriteLiveValues` shifts an explicit timestamp by the local↔UTC offset (~+4h) +**Symptom (live-proven, reproduces via raw `grpcurl` — no OtOpcUa code involved):** a `WriteLiveValues` +with an **explicit** `timestamp=2026-06-27T03:45:00Z` lands in the historian at +`2026-06-27T07:45:00Z` (+4h = the deployment's local↔UTC delta). A **server-stamped** write (null +timestamp) lands correctly at the gateway's UTC now. The OtOpcUa value-writer sends correct UTC +(`Timestamp.FromDateTime(SpecifyKind(ts, Utc))`), so the shift is in the gateway's SQL write path. + +**Impact:** the continuous-historization recorder writes the driver's **source** timestamp (explicit), +so historized values would carry timestamps offset by the host's UTC offset until fixed. (The OtOpcUa +live write test currently uses a ±12h tz-tolerant readback window to validate *persistence* around +this — see FU-2 acceptance.) + +**Investigation (gateway repo):** `SqlLiveValueWriter` (the `aaAnalogTagInsert` + `INSERT INTO History` +path). Inspect which `History` DateTime column is written (local vs `*UTC`) and the conversion applied +to the incoming proto UTC `Timestamp`. The +4h (value lands *later* than supplied UTC) is consistent +with writing a UTC value into a **local** column that `ReadRaw` then converts local→UTC, on a server +whose offset is −4h (EDT). Compare against the **server-stamped** path (which is correct) to see what +conversion the explicit path is missing. + +**Proposed fix:** convert the supplied UTC timestamp to the historian server's local time before the +`History` insert (or write the UTC-typed column), so an explicit UTC timestamp round-trips unchanged. +Add a gateway unit/live test: write explicit `T`, read back, assert the sample timestamp == `T`. + +**Acceptance:** an explicit-timestamp `WriteLiveValues` reads back at the supplied UTC time. Then +**tighten** the OtOpcUa live write test (`Write_then_read_on_sandbox_tag`) back to a narrow recent +window anchored on the write time. + +--- + +## Priority 2 — OtOpcUa-side follow-ups +**Owning repo: `~/Desktop/OtOpcUa` (this repo).** + +### FU-3 — Continuous-historization `HistorianTagname` override edge case +The `ContinuousHistorizationRecorder` registers `DependencyMuxActor` interest **by the resolved +historian name** (`HistorianTagname` override else `FullName`) — the same key the EnsureTags hook and +the writer use. The mux fans `DependencyValueChanged` **keyed by `FullReference`** (the driver's +published ref). In the **common case (no override)** historian-name == `FullReference`, so it's fully +consistent and works (live-validated path is the value writer; mux fan-out is the recorder's input). +**When a `HistorianTagname` override is set** (override ≠ `FullReference`), the recorder registers +interest under a key the mux never fans → that tag's values are never captured. +**Fix options:** register mux interest by `FullReference` (the mux key) while writing to the historian +under the resolved historian name — i.e. carry both identifiers through `IHistorizedTagSubscriptionSink` +/ the recorder (a `(muxRef, historianName)` pair) instead of a single string.

The applier resolves MuxRef = FullName and HistorianName = override-or-FullName. The recorder now keeps a muxRef->historianName map: it registers/filters mux interest by MuxRef but writes the outbox entry (and drains) under HistorianName. The convergence handler re-registers the mux only when the registered key-set changes, so an override-only rename (same FullName) updates the write target without mux churn.

The muxRef->single-name map collapsed last-wins, so under alias + divergent overrides only one historian tag got the value and the rest were silently dropped — the exact failure class FU-3 exists to eliminate. Model the fan as muxRef -> HashSet and append ONE outbox entry per name in OnValueChangedAsync (a per-name append failure drops only that name and continues). Convergence removes/adds each (muxRef, name) pair individually from the per-ref set, dropping the mux key only when its last name is removed — so removing one alias leaves the shared ref fanning for the others with no mux churn. Tests: aliased-refs-each-get-the-value (one fan → both historian names written), removing-one-alias-keeps-the-ref-registered, and the override-rename test now feeds a value post-rename to prove the write target actually moved to the new name.
