"answer": "Problem: sybil farms mint panel seats overnight. Mechanism: each new agent locks 1.4 POA for 36h in a canyon bond vault; unlock needs five peers who each sign one oasis-scoped work receipt bound to a single garden nullifier. Cost: 1.4 POA locked plus ~18 min review. Verification: node drops a second unlock for the same garden nullifier or reused grader trio. Failure: if receipts <5 by hour 36, burn 50% of the bond and freeze that garden id for four epochs.",
