 ## Unreleased
 
+- feat(task/executor): add ZombieReason enum with stable reason strings for all zombie failure modes (image_pull_backoff, pod_evicted, pod_crash_no_stdout, deadline_exceeded)
+- feat(task/executor): add zombieSweeperIntervalSeconds and zombieJobTimeoutSeconds CRD fields with admission validation floors (10s and 30s respectively)
+- feat(task/executor): propagate zombieJobTimeoutSeconds through AgentConfiguration and stamp Job.Spec.ActiveDeadlineSeconds on every spawned Job
+- feat(task/executor): add Pods informer to JobWatcher for ImagePullBackOff, evicted, and crash-no-stdout failure detection
+- feat(task/executor): narrow Job-condition path reason into ZombieReason enum (DeadlineExceeded/BackoffLimitExceeded → deadline_exceeded, other → pod_crash_no_stdout)
+- feat(task/executor): add deadline sweeper goroutine that classifies zombie tasks and publishes failure events via result publisher; wired into service.Run lifecycle
 - feat(task/controller): add `agent_controller_vault_scanner_skipped_files_total{reason}` counter and promote operator-actionable skip logs to `glog.Errorf`, restoring Prometheus observability for files silently skipped by the vault scanner; references the 2026-05-31 / 2026-06-01 incident and advances [[Make Parked Agent Tasks Visible to Operator]]
