…ith mutual TLS The instance manager's remote webserver previously had no caller authentication, meaning any process with access to the pod network could trigger backups, instance manager upgrades, or WAL archival operations. The operator now generates an in-memory ECDSA P-256 client certificate on startup and reconciles its SHA-256 public key fingerprint into the cluster status. The instance manager reads the expected fingerprint from its cached cluster object and rejects requests to sensitive endpoints that do not present a matching certificate.
