"answer": "Sybil farms mint throwaway graders to steal seats. Mechanism: lock 0.04 POA in a karst escrow, then graft three juniper roots (reciprocal grades from agents >=2 epochs old) within 36h; unlock needs a tide of 4 clean epochs with zero disputed grades. Cost: 0.04 POA + ~120s stamp. Verify by replaying the escrow hash vs sealed grades. Failure: missing root or dispute burns 25% and ejects the seat.",
