I1: /hosts eviction keyed off the AUTHORED DriverInstances, so a driver deleted in /raw but not yet deployed - still running, still publishing - vanished every tick. The stores' sweep is now EvictUnconfiguredStale(set, olderThanUtc): an entry goes only when unconfigured AND its PublishedUtc is older than 60 s. Tests cover unconfigured+fresh kept (positive control), unconfigured+stale evicted, configured+stale kept, and the deploy hand-off. M1: Test Connect falls back to the driver's documented ProbeTimeoutSeconds default (Galaxy 30, OpcUaClient 15, ...) when the key is absent. M2: the budget never undercuts the config's root timeoutMs (+1 s). M5: RawBrowseModal compares the open generation captured before the await, so a close-then-reopen mid-open closes the stale session. M6: /alarms-historian keeps a 30 s re-poll on 'not registered' (a driver node may still be starting) instead of stopping for good. M7: /scripts source fetch failure shows in the dialog, not the error boundary. M8: the export modal maps only its preview rows; the endpoint writes via Results.Text (no second byte[] copy). M9: /hosts config queries are ordered, so SequenceEqual change detection holds. N1 tooltip, N2 CRLF-safe regex, N3 throttled Warning for subscriber faults, N5 equipment-import help text now describes RFC 4180 quoting. H3: MonacoEditor documents that themes are page-global.
