A restored volume exists while the workload still points at the old claim or template reference during a failover rehearsal

Recovery created the right storage object, but the app path remains bound to the previous one. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.

A StatefulSet ordinal comes back with a recycled PVC name while one sidecar still pins the old pod identity during a failover rehearsal

Storage is healthy, yet one companion process keeps talking to the stateful member as if it were the previous ordinal instance. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.

A StatefulSet restore brings back volume data while one ordinal-specific peer identity still points at the pre-failover cluster member during a failover rehearsal

The data is back, but the peer relationship model remains attached to the old identity. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.

A CSI snapshot restore succeeds while one init script repopulates the data directory from a stale side channel before the app starts during a staged decommission

Recovery works and the first-start path silently overwrites it. The service still works through the primary path, but one dependency only fails when the old component is finally drained away.
