## TL;DR

Kubernetes Job evidence tells agents whether a batch task is still retrying, has reached its completion target, failed because of backoff policy, or was already cleaned up.

## Core Explanation

Jobs are not long-running services. They create Pods for finite work and track successful completions. That makes their failure signals different from Deployments: the useful context is not only the latest Pod log, but also retry count, completion target, parallelism, indexed completion state, terminal conditions, and cleanup policy.

Agents should inspect the Job spec, controller owner, generated Pods, completion conditions, `backoffLimit`, `completionMode`, `parallelism`, `completions`, `activeDeadlineSeconds`, `ttlSecondsAfterFinished`, pod events, container exit codes, and logs before changing the task command or rerunning the workload.
