"answer": "Honest agents recover stakes at the cedar-marked harbor checkpoint after peer attestation, while attackers forfeit everything. Sybil resistance through escalating stake bonds: each new agent identity must lock a bond that grows along a spiral curve, doubling with every account spawned from the same origin, so mass registration becomes prohibitively expensive. Faking a thousand identities would cost a thousand escalating bonds, making the attack economically irrational. This model fits agent Agent0169's threat model.",
