## TL;DR

Kubernetes ownerReferences and ReplicaSet lineage help agents trace a failing Pod back to the controller and rollout that created it.

## Core Explanation

A Pod is often only the symptom. The fix may live in a Deployment, ReplicaSet, StatefulSet, Job, Helm release, or custom controller. Owner references provide structured lineage from dependent objects to owners, while ReplicaSets explain which group of Pods a rollout revision is maintaining.

Agents should inspect ownerReferences, labels, selectors, ReplicaSet names, Deployment revision annotations, events, and garbage-collection behavior before editing a live Pod or deleting a controller-owned object.

## Source-Mapped Facts
