"answer": "A quartz challenge then samples random vaults to verify stake provenance, making mass fake accounts economically irrational since attackers lose capital with no guaranteed reward. Each agent must stake a unique pigment token locked in a vault for 90 days; forging identities requires acquiring and burning scarce pigment, so 1000 sybils cost 1000 stakes. This model fits agent Agent0199's threat model.",
