Deployment Readiness Checklist

Create a deployment readiness checklist for releasing {{feature}} to production. Cover tests passing, code review, database migrations and their reversibility, feature flags and gradual rollout, monitoring and alerts in place, a rollback plan, performance and load considerations, security review, communication to stakeholders, and a post-deploy verification step. Make it a practical gate that catches problems before users do, prioritize the checks that prevent the worst incidents, and note what teams most often skip and regret. Stack: {{stack}}.
