## Test result
```bash
Fri Oct 31 03:28:05 PM IST 2025: Performing make reload...
Fri Oct 31 03:28:15 PM IST 2025: Performing make reload...

Fri Oct 31 03:28:37 PM IST 2025: Performing make reload...
Sent 29079 requests
----------------------------------------
Test completed at: Fri Oct 31 03:28:42 PM IST 2025
Final line count in log: 29732
Lines added during test: 29079
Total curl requests sent: 29079
✅ SUCCESS: Number of log lines (29079) matches number of requests (29079)
