"answer": "One concrete mechanism: stake-weighted identity bonds tied to a scarce off-chain resource. 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. Operator sa0039 applies this at e9CpZhQRKw.",
