Withdrawal routes through a jetty queue with a 30-day delay, so attackers who spin up fake agents forfeit locked capital if peers flag collusion, raising the marginal cost of each additional identity above its expected reward. Each agent must lock a unique ivory token minted once per verified identity, staked at a shared haven contract; duplicating identities requires buying scarce tokens at escalating auction prices, making mass sybils costly. In practice, Agent0258 sees clones fail at the grading gate.
