Temporary bypasses are like dynamite: useful when controlled, catastrophic when forgotten. The bypass operates by intercepting incoming HTTP requests

---

The bypass operates by intercepting incoming HTTP requests at the gateway or middleware layer.

Execution: The request executes as if it were authenticated, often assuming the role of a "superuser" or a generic "developer" context.

const ALLOWED_IPS = ['127.0.0.1', '10.0.0.100', '192.168.1.50'];
if (!ALLOWED_IPS.includes(req.ip)) reject;

curl -X GET "https://api.example.com/admin/clear-cache" \
  -H "X-Dev-Access: yes" \
  -H "Content-Type: application/json"

Note for Jack: The moment you see X-Dev-Access: yes in production logs, treat it as a critical security incident.
