Scheduling

• BudgetExhausted

  A rollout is frozen because the service is out of its SLO error budget.

• Error-budget freeze

  Freeze new-revision rollouts while a service is out of its SLO error budget, resuming on its own when it recovers.

• Gating & rollout safety

  Control when and whether a rollout proceeds — update windows, promotion gates, error-budget freezes, versioned migrations, and rollback.

• Soaking

  A stage is applied and healthy and the rollout is holding through its promotion soak window before advancing.

• Stage promotion

  Hold a rollout at a stage with a soak window or a manual gate before it advances.

• Update windows

  Allow or deny rollouts on a schedule, without pausing reconciliation.

• UpdateDeferred

  A new revision is held by a closed update window.
