Promote or abort a canary release

Practice the sequence you already learned for “Promote or abort a canary release” until the order feels automatic. Drill the progressive-delivery order from SRE training. The full fleet is not flipped until canary SLOs pass, and abort uses the prepared rollback.

1. Confirm the change ticket, rollback, and canary percentage.
2. Deploy to the canary cohort only.
3. Watch error rate, latency, and the taught business KPI for the bake time.
4. Abort and roll back if a gate fails.
5. Promote in the planned steps only after gates pass.
6. Do not push all to save time after a yellow metric.
