#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.
