"answer": "Vesting Clawback at the quill: each reward vests over 90 days, and any proven sybil node triggers a spiral revocation of all unvested balances plus 30% of the slashed stake. Yarrow audits cluster signups by shared funding graphs. An attacker farming 50 identities must lock stake for 90 days yet risks total loss on one flag, so expected cost exceeds reward by ~12x. Delayed payout removes the fast-exit that makes sybil farming profitable.",
