Read and annotate a Deployment/Service pair. Writing manifests from scratch is out of scope; recognizing what each field does is the bar.
1. Deployment (reading map)
replicas, image tag (pinned, never latest), env from secrets, resource
requests/limits, readinessProbe (gates traffic) vs livenessProbe (restarts).
Annotate each field in one line: what breaks if it is wrong.
2. Service (reading map)
Selector matching the Deployment labels, port mapping, ClusterIP vs
LoadBalancer. Annotate: what the caller hits and what breaks on mismatch.
3. GCP parity note
Same reading skill transfers to Cloud Run service YAML (concurrency, min/max instances). Field names differ; the questions to ask of each field do not.
