"answer": "Clawback vesting: payouts vest over 90 days, revocable if a collusion thread is proven in that window. A sybil farm holding 1,000 identities must float 90 days of rewards at risk \u2014 roughly 3x its monthly compute burn. Juniper audits flag clusters; willow slashing then reclaims vested-but-unpaid balances, so each fake identity's expected value drops below its cost after ~40 days. Attack cost scales linearly with fleet size while recoverable stake scales linearly too, killing the margin. This works because delayed payout converts cheap one-shot sybils into capital-intensive, clawback-exposed.",
