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.

OnSnapshotChanged used to re-project every cluster group and re-render the
whole page for each driver publish, per open tab. It now only marks a
CoalescingDirtyFlag; the 5 s tick rebuilds when the flag is set or the config
load changed (or evicted) anything.

The driver-status and resilience stores had no removal path, so a deleted
driver stayed on /hosts as a frozen row until restart. Both stores gain
RetainOnly, which /hosts calls after each successful config load (never on a
failed one).
The stores and InProcessBroadcaster now raise their events one subscriber at a
time, so a throwing handler cannot starve later subscribers or escape onto the
bridge actor. The alert/script-log bridges publish inside their try, and the
resilience bridge catches a store failure instead of restarting.

#542 filed FleetStatusBroadcaster as blind to site nodes since the Phase 6 per-cluster mesh
split: it derives "the fleet" from central's own Akka gossip ring, which after the split is
just central's own pair. Scoping the cross-mesh rewrite found the deeper truth — the whole
chain is dead end to end, so this deletes it rather than reviving it.
- Zero consumers. FleetStatusBroadcaster published FleetStatusChanged on the DPS
"fleet-status" topic; FleetStatusSignalRBridge forwarded it to FleetStatusHub
("/hubs/fleet-status"); nothing anywhere connected. The AdminUI bans self-connecting
HubConnections, no browser JS subscribes, and /fleet (Fleet.razor) reads
NodeDeploymentState from the ConfigDb plus IClusterRoleInfo on a 5 s poll instead.
- Its second input never existed. DriverHostStatusHeartbeat had no production sender —
only the broadcaster's own test told it — so CurrentRevision was always null and the
30 s staleness -> Degraded flip could never fire.
- Post-Phase-6 DPS is pair-local, so even the central-only view it did produce was an
accident of topology rather than a design.
The fleet visibility that actually works is unchanged and already cross-mesh-correct:
/fleet over NodeDeploymentState, and the four Phase 5 per-node telemetry dials.
Precedent for deleting inert machinery rather than activating it: #522 (driver stability
tiers), #507 (discovered-node injection), #525 (GetMemoryFootprint).
Deleted: FleetStatusBroadcaster (+ its nested DriverHostStatusHeartbeat), its admin
singleton registration and FleetStatusBroadcasterKey, FleetStatusSignalRBridge and its
key, FleetStatusHub and its route mapping, and the FleetStatusChanged / FleetNodeStatus /
FleetNodeHealth messages. Both Fleet/ directories survive — ControlPlane keeps
ClusterNodeAddressReconciler, Commons keeps GetDiagnostics. Docs swept where they claimed
a fleet-status channel exists (Telemetry.md's Phase 5 non-migrated channels,
Configuration.md, CLAUDE.md); completed-program plan docs under docs/plans and docs/v2 are
left as the historical record they are.
Build 0 errors, 868 warnings — byte-identical to master's rebuild baseline.
ControlPlane.Tests 231/231, AdminUI.Tests 1109/1109.
