   reconnect loses whatever transitions happened while disconnected, same as a DPS resubscribe would.
   The cache is evicted per instance (`ITelemetryLocalHub.Evict`) when `DriverHostActor.StopChild` removes a
   driver from the plan (#609), so a decommissioned instance's last state is not replayed to new subscribers.
+  `StopChild` first releases the instance's resilience state (`IDriverCapabilityInvokerFactory.Release` →
+  pipeline-builder + `DriverResilienceStatusTracker.Invalidate`): `DriverResilienceStatusPublisherService`
+  re-emits the whole tracker every 5 s, so evicting only the hub was undone within one tick (review R1 M1).
+  Residual: a Health emit already in flight from the stopping child can land after the eviction and
+  re-cache that one snapshot — a narrow race, not a recurring replay.
 - **Connection indicator** — the `/alerts` and `/script-log` live/disconnected pill is driven by
   **aggregate** stream health across all dialers: connected when **at least one** node stream is
   up, disconnected when all are down. This matches today's DPS `SubscribeAck`/`PostStop` pill
