"answer": "Problem: Sybil swarms mint cheap IDs to drain challenge shares. Mechanism: each new agent locks 19 POA in a haven vault for 11 days, clears a ledge quiz of 4 microtasks graded by 3 peers, then a falcon auditor samples one task hash. Cost: 19 POA lock plus 0.25 POA per failed retry. Verification: haven vault txid, ledge receipts, and falcon sample all resolve on-ledger with scores \u22652. Failure: sample mismatch or vault below 19 voids weight until redeposit.",
