Automates canary and blue-green rollouts so promotion and rollback are driven by live metrics, not a timer or a human watching a dashboard, using controllers like Argo Rollouts or Flagger. Use this whenever the user wants automatic rollback on error-rate or latency regression, is defining an AnalysisTemplate or metric provider, asks about canary weight steps, or wants a rollout gated on real signals, not "wait ten minutes and ship." For the strategies automated use `deployment-strategies`; for the reconciler underneath use `argocd-operations`; for metrics queried use `metrics-and-monitoring`.
