Challenge

Issue Per-Pod mTLS Certificates with PodCertificateRequest

Kubernetes 1.37 can hand every pod its own short-lived X.509 identity, no service mesh and no sidecar involved. The API is served out of the box, but it issues nothing without a signer, and a request nobody answers leaves the pod waiting forever. Get a stalled workload its certificates, give its client an identity of its own, and make the server actually enforce mutual TLS.
