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).

The HistorianGateway driver is now the sole historian read/write+alarm backend, so the
Wonderware sidecar projects are dead code. Removes the 5 Wonderware projects (driver,
.Client, .Client.Contracts, + their 2 test projects) from the solution and tree, and fully
retires the vestigial 'Historian.Wonderware' driver type (UI/probe-only; it had no driver
factory): the Host probe registration, the AdminUI driver-config surface (driver page,
tag-config editor/model/validator entry, address picker/builder, driver-type catalog +
dropdown + edit-router entries), and their tests. Prunes the now-unused Wonderware
connection fields (Host/Port/UseTls/ServerCertThumbprint/SharedSecret) from
AlarmHistorianOptions (keeping Enabled + the SQLite store-and-forward knobs) and refreshes
the stale XML docs that named Wonderware as the production backend.

AdminUI driver-instance pages serialized enum config fields (S7 CpuType,
Modbus DataType/Region, AbCip PlcFamily, ...) as JSON *numbers* because each
page's _jsonOpts lacked a JsonStringEnumConverter. The driver factories,
however, deserialize into string-typed DTOs (+ lenient ParseEnum) and throw
when binding a JSON number to a string? — so an AdminUI-authored config
containing any enum field produced a blob the driver could not parse,
faulting the driver on deploy. Proven end-to-end for S7 and Modbus; latent
for AbCip/AbLegacy/TwinCAT/FOCAS/Galaxy/Historian. Only OpcUaClient was safe
(its factory + probe already carried the converter).
Add JsonStringEnumConverter to all 9 driver-instance pages' _jsonOpts and the
8 missing driver probes' _opts (factories unchanged — already string-via-
ParseEnum; strictly more permissive, also lets pages load hand-seeded
string-enum configs back into the form).
Also fix DriverProbeHandshakeE2eTests.AbCip_Green_AgainstSim to probe a real
sim tag (TestDINT) — the no-tags @raw_cpu_type fallback is rejected by the
ab_server sim with ErrorBadParam (a real ControlLogix returns ErrorNotFound,
which the probe treats as reachable; hardware-gated follow-up).
Tests: reflection guard over all driver pages' _jsonOpts (AdminUI.Tests);
factory round-trip + numeric-form-throws guards for S7 and Modbus.
Found by running the never-before-run FB-9/FB-10 live verifies.
Code-review nits: trim the seed name so the in-session dropdown label matches
the server-trimmed persisted name; add a null-selectedId test for
ResolveScriptLabel; and note in CreateNewScriptAsync that the ordering
invariant is proxied by the pure helper (AdminUI has no bUnit).
After inline "New script" creates an SC-… id, the entry is now added
to _scripts BEFORE _form.ScriptId is set so the <InputSelect> has a
matching <option> on first render and the displayed label is correct.
Extracts VirtualTagModalHelpers.ResolveScriptLabel as a testable pure
helper (5 new unit tests in VirtualTagScriptDropdownTests).
The OPC UA address-space build pipeline was named after a v2-roadmap
milestone number rather than its domain. Rename the family to describe
what it does (build/diff/apply the OPC UA address space):
Phase7Composer -> AddressSpaceComposer
Phase7CompositionResult -> AddressSpaceComposition
Phase7Planner -> AddressSpacePlanner
Phase7Plan -> AddressSpacePlan
Phase7Applier -> AddressSpaceApplier
Phase7ApplyOutcome -> AddressSpaceApplyOutcome
The 9 Phase7*Tests suites follow suit; Phase7ScriptingEntitiesTests ->
ScriptingEntitiesTests (it tests the scripting migration, not the
pipeline). Log-message prefixes move to the new class names.
Pure mechanical rename, no behavioral change. EF migration classes/IDs
(AddPhase7ScriptingTables, ExtendComputeGenerationDiffWithPhase7) are
immutable and left untouched, as are historical design docs.
Build clean; OpcUaServer 261/261, Runtime 272/272, ScriptingEntities
12/12 green.
Subscribe ConnectionStateChanged before reading IsConnected (subscribe-then-read
idiom, matches DriverStatusPanel) so no transition is missed. Add
OnConnectionStateChanged handler that marshals to the circuit sync context via
InvokeAsync. Dispose unsubscribes both events.
Reconnect-overlay: App.razor loads _framework/blazor.web.js and contains no
custom #components-reconnect-modal element; .NET 10 Blazor's default reconnect
overlay is active automatically — no custom markup needed.
No unit tests; live-verify follows.
Dispose the CancellationTokenSource in AcknowledgeAsync and ShelveAsync
(the TimeSpan overload holds an internal timer — leaked without using).
Add StateHasChanged() to ShowOpResult so the result chip renders even if
a future caller omits the finally-block re-render.
