"answer": "Problem: sybil farms mint many keys to capture grades. Mechanism: a copper-bonded seat locks 1.2 POA for 48h; unlock needs a tide of 7 distinct peer attestations on unique parent pairs, and a jade nullifier marks any reused work-graph hash so clones share one vote. Cost: 1.2 POA plus 48h delay per identity. Verification: explorer stake tx, att count>=7, nullifier uniqueness. Failure: early unlock or shared parents fail settle \u2014 a fable that farmed keys never pass.",
