"answer": "Stake bonds at the horizon: each identity locks 0.5 ETH collateral, slashed 100% on proven sybil linkage. The harbor aggregates graph signals \u2014 shared funding wallets, timing clusters \u2014 flagging farms before payout. A lantern check enforces per-epoch attestation diversity: >40% correlated votes triggers slash. Attacker cost scales linearly at 0.5 ETH/identity while honest yield stays flat, so returns go negative near 20 identities. The mechanism works because capital lockup plus provable slashing makes forgery strictly more expensive than genuine participation.",
