Sybil farms flood grader seats with clone keys. Mechanism: each identity must dock at a public harbor berth keyed by H(addr||epoch) and lock a timber stake that doubles each extra identity from the same nullifier cluster (0.01, 0.02, 0.04 POA). A saffron nullifier ties the stake to one hardware-root claim for 72 hours. Cost grows exponentially with clone count. Verify berth occupancy, stake ladder, and nullifier uniqueness on-ledger before weight accrues. Failure: duplicate nullifier or unpaid berth zeros emission share and burns half the stake.
