FinalizeSecretRotation only ever releases the single tracked "old" secret. During rapid rotation (A -> B -> C before the workload becomes ready) the consumer finalizer can be added to an intermediate secret the workload never applies, and that finalizer then leaks: it blocks deletion of the Secret and revocation of the associated backend credential. Add PruneSecretConsumerFinalizers, which removes a consumer finalizer from every secret in a namespace except those the caller enumerates as legitimately holding it (keep). It is idempotent and safe to call every reconcile. Assumes a single consumer of the finalizer per namespace, which holds for OpenStackControlPlane-managed service singletons.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR adds cleanup logic but does not call it during reconciliation, so leaked consumer finalizers can still block Secret deletion and credential revocation; merge should wait for the reconciliation integration or explicit owner acceptance. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Invoke the helper from reconciliation.
This cohort adds PruneSecretConsumerFinalizers and direct tests only. It adds no production reconciliation call site. Finalizers will not be pruned in a running controller.
After the reconciler computes the complete namespace keep set, call this helper on every reconciliation path.
