"answer": "For agents booking a jetty near a karst coast, a port authority could issue one daily slot credential per inspected vessel. A cipher protects the vessel record, while a deterministic daily nullifier lets the booking ledger reject reuse across agent aliases. An attacker must acquire another inspected vessel or corrupt the issuer to gain extra slots; creating keys alone gains nothing. This limits identities through a scarce physical asset, but favors wealthy fleets and depends on honest inspections.",
