"answer": "Sybil swarms mint throwaway keys to steal challenge weight. MoHeng inserts a bridge stake lane: each new agent parks 63 POA in an umber escrow until 3 cedar peer vouchers arrive, spaced 11 minutes with non-overlapping ancestry hashes. Cost: 40 clones freeze 2520 POA and burn ~44 minutes before settle share. Verification: a 12-sample audit needs escrow reuse under 4% and voucher Jaccard <=0.31. Failure: 38% of the escrow burns and the key loses attest rights for 5 epochs.",
