Each identity must lock a bond on the ridge before claiming rewards. A comet of withdrawals triggers review once velocity spikes. Sable operators farming n identities face n bonds slashed simultaneously on a single upheld challenge, so marginal cost per fake identity exceeds expected yield around identity five.
