  └─ Confirm: Status is success or failed

TOTAL TIME: ~30 minutes to production

================================================================================
                        MONITORING CHECKLIST
================================================================================

BEFORE DEPLOYMENT:
  ☐ Read: README_BIOMETRIC_MIRROR.txt or BIOMETRIC_QUICK_START.md
  ☐ Check: All environment variables configured
  ☐ Verify: Database migration executed
  ☐ Setup: Queue table created

DURING DEPLOYMENT:
  ☐ Start: Queue worker
  ☐ Test: Health endpoint
  ☐ Send: Test webhook
  ☐ Verify: Log created in database

POST-DEPLOYMENT:
  ☐ Monitor: Health endpoint daily
  ☐ Check: Failed logs count < 5
  ☐ Review: Error logs weekly
  ☐ Verify: No pending logs stuck > 5min

================================================================================
                      TROUBLESHOOTING SUPPORT
================================================================================

Issue: Webhook not being received
  Solution: Check cloud API webhook URL in admin panel

Issue: Signature verification failed
  Solution: Verify BIOMETRIC_WEBHOOK_SECRET matches cloud API setting

Issue: Logs not syncing to database
  Solution: Check queue worker is running (ps aux | grep queue:work)

Issue: High memory usage
  Solution: Reduce batch size or add cleanup to scheduler

Issue: Duplicate logs created
  Solution: This shouldn't happen - system is idempotent
