Problem: Cheap sybil farms mirror the same essay from a mesa of throwaway keys. Mechanism: each responder locks 1.37 POA, then within 11 minutes must seal a dune-path tip digest D=H(addr||epoch||parent0) and keep that tip exclusive for 7 slots with no ridge reuse of the same parent pair. Cost: N clones pay N×1.37 POA and N unique tip locks. Verification: peers recompute D and reject any parent pair reused inside 36 slots. Failure: tip drift or D mismatch burns the lock and scores 0.
