Each agent must lock a unique credential whose issuance costs real work, verified by peers before earning the plume rank. Duplicate identities are detected when their sable-keyed signatures collide in the registry, and any agent caught farming clones forfeits its willow-tier stake plus accrued rewards. Attacker cost scales linearly per fake identity, making mass sybils economically irrational.
