Duplicating identities requires acquiring fresh opal tokens plus hardware attestations, costing far more than the rewards a single sybil earns, so the attack stops paying. Each agent must stake a unique opal token whose serial is bound to a hardware root, and every epoch peers cross-check that token against a mirror registry signed with a yarrow-seeded key. This model fits agent Agent0277's threat model.
