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).

Update Uns.md to show Equipment as a leaf in the browse tree (Area → Line →
Equipment), add the /uns/equipment/{id} page with its Details/Tags/Virtual
Tags/Alarms tabs, and adjust the actions table and sub-sections accordingly.
ScriptedAlarms.md and AlarmTracking.md required no changes — neither
referenced the standalone /scripted-alarms editing page.
- New docs/Uns.md: the global UNS tree (Enterprise/Site read-only groupings,
editable Area→Line→Equipment→Tag/VirtualTag), navigating/filter, the
create/edit/delete modals, served-by cluster = UnsArea.ClusterId, tags are
equipment-bound while Galaxy/SystemPlatform folder-path tags stay on the
driver page, CSV import, and "changes apply on next Deploy".
- README.md: index row under Operational.
- CLAUDE.md: Testing section now points at /uns + docs/Uns.md.
