If unavailable, perform these checks manually: identify table lock duration, confirm a rollback path exists, enumerate backfill steps, and run `EXPLAIN ANALYZE` on affected queries.\n2. **Choose deployment pattern:** expand-contract for column changes (see Key Safety Rules above), phased rollout for table-level changes, zero-downtime for everything touching large tables.\n\n**HARD GATE — Migration Safety Check:**\n- [ ] Safety risks reviewed; rollback strategy defined and tested\n- [ ] Performance impact assessed with `EXPLAIN`\n- [ ] Backfill requirements and deployment order identified\n\n**If gate fails:** Redesign the migration approach before proceeding.\n\n---\n\n## Phase 2: Development Testing\n\nDeploy each migration file independently.\n\n**Test each migration in sequence:**\n```bash\nrails db:migrate && rails db:rollback && rails db:migrate\nbundle exec rspec spec/models/order_spec.rb spec/features/order_flow_spec.rb\n```\n\n**HARD GATE — Development Tests:**\n- [ ] Each migration runs, rolls back, and re-runs successfully (idempotent)\n- [ ] Application tests pass; no N+1 queries introduced\n\n**If gate fails:** Fix migration or application code before proceeding.\n\n---\n\n## Phase 3: Staging Deployment\n\n**Prerequisites:** Staging DB must match production in size, data shape, and PostgreSQL version.\n\n```bash\nRAILS_ENV=staging bundle exec rails db:migrate\ncurl https://staging.example.local/api/health\ncurl https://staging.example.local/api/orders\nRAILS_ENV=staging bundle exec rails db:rollback\n```\n\n**HARD GATE — Staging Verification:**\n- [ ] Migration completes without errors on staging data volume\n- [ ] Smoke tests pass; error rate unchanged; rollback confirmed working\n\n**If gate fails:** Do not proceed to production. Fix and re-deploy to staging.\n\n---\n\n## Phase 4: Production Deployment\n\n**Pre-deployment checklist:**\n- Staging deployment verified\n- Team notified; deployment window scheduled during low-traffic period\n- Rollback command ready to execute\n\n```bash\nRAILS_ENV=production bundle exec rails db:migrate\n\n# Monitor in real-time\ntail -f log/production.log\nheroku pg:diagnostics --app production-app\n\n# Smoke tests\ncurl https://api.example.local/health\ncurl https://api.example.local/api/orders\n\n# Rollback if needed\n# RAILS_ENV=production bundle exec rails db:rollback\n```\n\n**HARD GATE — Production Monitoring (first 15 minutes):**\n- [ ] Migration completes without errors\n- [ ] Error rate < 0.1% (no spike from baseline)\n- [ ] p99 API latency < 500 ms\n- [ ] DB CPU and lock wait times within normal range\n- [ ] Smoke tests pass\n\n**If gate fails:** Roll back immediately if error rate or latency exceeds thresholds. Investigate before redeploying.\n\n---\n\n## Output Style\n\nWhen completing a migration cycle, produce a **Migration Report**:\n\n```\n## Migration Report\n\n**Plan**\n- Change: <description>\n- Pattern: <expand-contract | phased rollout | zero-downtime>\n- Rollback strategy: <steps>\n- Lock assessment: <duration and type>\n\n**Development**\n- Migration file(s): <paths>\n- Idempotent cycle: PASS | FAIL\n- Test suite: PASS | FAIL\n- N+1 check: PASS | FAIL\n\n**Staging**\n- Migration time: <duration>\n- Smoke tests: PASS | FAIL\n- Rollback tested: YES | NO\n\n**Production**\n- Deploy timestamp: <datetime>\n- Post-migration error rate: <rate> vs baseline <rate>\n- p99 latency: <ms>\n- Monitoring result: STABLE | ROLLED BACK\n```\n\n---\n\n## Error Recovery\n\n**Migration fails in production:**\n1. Assess error logs and database state\n2. If critical: `RAILS_ENV=production rails db:rollback`\n3. Investigate root cause → redesign → restart full cycle from Phase 1\n\n**Rollback itself fails:**\n1. Engage DBA for manual intervention\n2. Document incident and improve migration process\n","tagline":"Use when running a safe migration loop: plan, test up/down, staging, production.
