Rollback Procedure

To rollback a service, identify the last healthy release in the deployment dashboard, pause the rollout, redeploy the previous image tag, and verify service-level synthetic checks. For database migrations, prefer backward-compatible expand/contract releases.

Checkout rollback must verify abandoned reservation cleanup. Billing rollback must verify no payment capture job is running with mixed schema assumptions. Authentication rollback must keep previous JWKS keys published until all access tokens expire.
