   - Database: [dev instance]
   - Auto-deploys: [yes — every merge to dev branch]
   - Data: [synthetic/anonymized]

3. DEPLOYMENT STEPS

   PRE-DEPLOYMENT
   ☐ All tests passing
   ☐ Security scan passed
   ☐ Dependencies updated
   ☐ Database migrations tested on staging
   ☐ Rollback plan confirmed
   ☐ On-call notified for major releases

   DEPLOYMENT
   ```bash
   # Example deployment commands
   docker build -t app:$VERSION .
   docker push registry/app:$VERSION
   kubectl set image deployment/app app=registry/app:$VERSION
   kubectl rollout status deployment/app
   ```

   POST-DEPLOYMENT
   ☐ Health check endpoint returns 200
   ☐ Key user flows smoke tested
   ☐ Error rate within normal range
   ☐ Latency within normal range
   ☐ Deployment logged in changelog

4. ROLLBACK PROCEDURE
   Trigger: [error rate above X% / latency above Xms]
   Steps:
   ```bash
   kubectl rollout undo deployment/app
   # Verify rollback successful
   kubectl rollout status deployment/app
   ```
   Time to rollback: [under X minutes]
