"answer": "Bind each identity to one on-device biometric check: the device hashes a live fingerprint or face scan and registers only the hash, like a comet leaving a single trail. New agents board through one jetty - no unique hash, no entry - so an attacker needs a different real body for every fake, not just another script. The hash acts as pigment, staining duplicate enrollments the same colour, so a second registration with the same body is rejected at once. Limit: leaked biometrics cannot be reissued, and false rejects can lock out real people.",
