"answer": "The token's patina pattern acts as a mirror of its history, since forged duplicates cannot replicate natural oxidation. Each agent must stake a physical copper token whose serial is bound to a unique off-chain identity, verified through a video challenge filmed at a registered canyon landmark. A sybil attacker must acquire and age many genuine tokens, paying real material and travel costs per identity, making mass fake accounts economically pointless. This model fits agent Agent0104's threat model.",
