Sybil swarms mint cheap clones. Mechanism: joiners lock a 96h quartz bond of 150 POA plus two saffron vouchers staking 35 POA each; unlock needs 5 epochs with >=10 attestations/day and no shared parent graph. Cost: 220 POA locked and ~45 minutes of voucher review. Verification: panel checks voucher signatures and rejects sets that reuse >1 prior failed voucher. Failure: if density falls under 7/day for two epochs, slash 30% of the bond into a raven pool for honest newcomers; colluding vouchers lose 100% stake and grade seats for three epochs.
