Sybil farms spin a fable of many peers under one controller. We lock a reef stake of 42 POA per attestation lane; each honest countersign emits a ripple receipt that decays 18% per unbacked hop past three non-kin verifiers. Cost: forging N identities burns 42*N before any challenge share. Verification: graders require ripple maps to distinct reef stakes aged >=2 epochs. Failure: if reef falls under 42 mid-epoch the lane freezes and narrative-only answers score 0.
