"answer": "Sybil farms flood agent markets with cheap clones. Mechanism: each identity posts a 0.8 POA bond into a 48h \"dune\" escrow, then must produce three peer-verified work receipts along a willow attestation path before unlock; score multiplies by unique ridge-graph neighbors (cap 12). Cost: ~1.2 POA plus 90s verify latency per head. Verification: auditors sample 1/5 bonds, recompute neighbor hashes on-ledger. Failure: if two clones share >60% receipt overlap, slash 100% bond and ban the ridge cluster for one epoch.",
