An area or line could be named "Packaging" or "Line 1", save cleanly, and then
fail the NEXT deployment with UnsSegmentInvalid. Because a deployment snapshots
the whole database, one badly-named area blocked EVERY cluster's deploy - and
whoever hit that was usually not whoever typed the name. Only the equipment form
carried the rule; the deploy gate held its own private copy.
The rule now lives once, on Configuration.Validation.UnsSegment, and both ends
call it. DraftValidator no longer restates it.
Enforced in UnsTreeService, not just on the forms:
- Create/Update Area, Line and Equipment reject an invalid name before touching
the row.
- The CSV import reports a bad name as an ERROR, not a skip - a skip means "you
already have this row", which would tell the operator the equipment exists
when it does not. Good rows in the same batch still insert.
A form attribute could never have covered the import, and with no bUnit in this
repo a rule only a form enforces is also a rule no test can reach. The forms
keep an attribute for the immediate message, but it now references the shared
pattern rather than restating it - a second copy is how these drifted apart.
One behaviour change beyond the fix: UnsSegment.AttributePattern admits
"_default", which the equipment form's hand-written literal rejected. The form
was stricter than the gate it was mirroring, so a _default row was uneditable
through the AdminUI.
Tests: 41, falsified with three production mutations - dropping the CreateArea
guard reds exactly the CreateArea rejections, turning the import error back into
a skip reds only the import test, and narrowing AttributePattern reds only the
attribute/IsValid agreement. Every rejection is paired with a name that must
still be accepted, or a guard that refused everything would pass.
Live-verified on docker-dev: the area modal now refuses "Packaging" in place
with the rule spelled out, "packaging-b" saves, and a CSV import of two rows
reports Inserted 1 / Skipped 0 / Errors 1 naming the offending row - the path no
form attribute reaches. Rig cleaned up and a further deployment sealed.

Uns.md Tags section rewritten to the reference-only model (UnsTagReference list,
cluster-scoped picker, effective-name uniqueness, {{equip}}/RefName); CLAUDE.md
gains a v3 Batch 3 paragraph. ScriptEditor.md was updated by WP4.

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.
