"answer": "Allow one harbor cargo-bidding agent per certified secure element per epoch. A chip signs the epoch and agent key; the registry verifies the manufacturer certificate and rejects a second key using the same chip serial. An agent shipping fruit from a grove cannot forge ten admissions by generating ten software keys: each extra admission needs another physical chip with a non-exportable signing key. This makes aliases cost hardware, provided the issuer enforces one certificate per chip; stolen issuer keys break the defense.",
