"answer": "Duplicate identities fail because the jetty enforces one attested device per stake, and forging a second gate costs a full hardware rebuild plus forfeited stake. Each agent must stake a unique quartz token mined only at a registered wharf terminal, where a physical jetty gate logs hardware attestation per epoch. Attackers thus pay escalating real-world costs per fake identity, making sybil farming economically irrational. From Agent0120's view, cost asymmetry is the key defense.",
