GitOps Reconciler
Software componentInfrastructureInfrastructurearc:GitOpsReconciler
An in-cluster, pull-based controller that continuously compares declarative desired state in a version-control repository with live cluster state and applies diffs until they match.
Responsibility. Keeps cluster state converged to version-controlled desired state.
Also known as: Continuous reconciliation, GitOps continuous delivery

Design guidance
- SHOULD treat the repository as the single source of truth and revert unauthorized manual changes.
- SHOULD assess resource health (replicas ready, endpoints bound) after sync rather than declaring success on apply.
- SHOULD roll back by reverting commits (not resetting history) so rollbacks are recorded and reviewable.
- SHOULD periodically rebuild clusters from the repository to validate disaster recovery.
Quantitative guidance
As stated by the sources; verify before use.
- Repository polling typically every few minutes (~3 minutes) (Ch4.4).
