The intended approach is: Use Pod events and scheduler reasons to diagnose Pending workloads before changing application images or reading nonexistent logs. Validate with: Inspect kubectl describe Pod events, requests, node taints, PVC claims and node affinity.

Validate with: Compare imagePullPolicy, local image cache, registry digest, pull events and Pod imageID.

Temporary data is disposable while durable application records remain accessible across Pod recreation. That result validates Ephemeral emptyDir versus persistent volumes rather than the requirement here. Verify instead: The PVC binds to a suitable volume and survives recreation of the application Pod as designed. Workload context: An admin deletes a Pod and expects its bound persistent volume's underlying data to disappear automatically.

That result validates ServiceAccount and workload RBAC boundaries rather than the requirement here. Verify instead: Workloads function under least privilege and operations needing prohibited capabilities are rejected or explicitly reviewed. Workload context: A team specifies a restrictive seccomp profile but its runtime ignores an unsupported profile name and administrators must check enforcement.
