+### phase21_performance_indexes
+
+Adds four composite indexes covering the highest-traffic multi-column query patterns: `(facility_id, inspection_date)` and `(inspector_id, inspection_date)` and `(status, inspection_date)` on `inspections`; `(facility_id, status)` on `issues`. All single-column indexes already exist from phase12. Uses `INFORMATION_SCHEMA.STATISTICS` existence check — safe to re-run.
+
+**Deploy order for phase21:**
+```bash
+flask db upgrade
+sudo systemctl restart gunicorn
 ```
