name: release-checklist description: Pre-deployment verification checklist covering build health, migrations, feature flags, rollback readiness, and environment parity. Use before deploying to production, after major features, or when preparing releases.

Release Checklist

Comprehensive pre-deployment verification to ensure safe, successful releases.

Pre-Release Verification

1. Build Health

• npm run build completes without errors
• npm run type-check passes (TypeScript strict mode)
• npm run lint passes with no errors
• No console warnings in build output
• Bundle size within acceptable limits

2. Database Migrations (per CLAUDE.md workflow)

• All migrations generated with npm run db:generate -- --name <change>
• Migration SQL reviewed in drizzle/migrations/
• Migrations applied to staging: npm run db:migrate
• No destructive migrations without data backup plan
• Rollback migration prepared if needed
• Schema changes backward compatible (or coordinated deploy)

3. Environment Configuration

• All required env vars documented in .env.example
• No hardcoded secrets in codebase
• Environment parity: dev/staging/prod configs aligned
• New env vars added to Vercel project settings
• Supabase project settings updated if needed

4. Feature Flags (per AGENTS.md)

• New features behind flags if risky
• Flag defaults appropriate for production
• Gradual rollout plan defined
• Kill switch ready for new features

5. API Compatibility

• Breaking API changes versioned under /api/v{n}
• Deprecated endpoints still functional
• Response contracts unchanged or backward compatible
• Webhook integrations tested (leads-intake, etc.)

6. Authentication & Authorization

• New routes protected with requireUser() or requireRole()
• Permission checks via ensureClientAccess() verified
• No new privilege escalation paths
• Session handling unchanged or tested

7. Data Integrity

• Soft delete patterns maintained
• No orphaned records from new relationships
• Activity logging added for new mutations
• Existing data compatible with schema changes

8. Performance Verification

• No N+1 queries introduced
• Large lists virtualized (TanStack Virtual)
• Images optimized via Supabase transforms
• Caching headers on new API routes

9. Observability (per AGENTS.md)

• Structured logging for new server actions
• Sentry error boundaries on new routes
• PostHog events for new user actions
• No sensitive data in logs

10. Rollback Readiness

• Previous deployment tagged/noted
• Database rollback plan if migrations fail
• Feature flags can disable new functionality
• Vercel instant rollback available

Deployment Process

Staging Verification

1. Deploy to Vercel preview
2. Run smoke tests on preview URL
3. Verify new features work as expected
4. Check for console errors
5. Test with both ADMIN and CLIENT roles

Production Deployment

1. Merge to main branch
2. Monitor Vercel deployment
3. Verify production URL
4. Check Sentry for new errors
5. Monitor PostHog for anomalies

Post-Deployment

• Smoke test critical paths
• Verify database migrations applied
• Check external integrations (email, webhooks)
• Monitor error rates for 30 minutes
• Communicate release to stakeholders
