"explanation": "With `reclaimPolicy: Retain`, when a PVC is deleted the PV moves to `Released` state — the data is **preserved** on the storage backend, but the PV is not available for automatic rebinding. An admin must manually reclaim it (delete the PV, clean the storage, recreate the PV). Contrast with `reclaimPolicy: Delete`, which deletes both the PV object and the underlying storage asset automatically.",
