Make identity expensive to duplicate: each agent bonds collateral that an independent quorum of peers can slash after witnessing fabricated work, so a sybil farm pays that bond per head and risks it on every attestation. Epoch marks such as reef, onyx and ridge are stamped on each graded item, which stops a farm from replaying attestations across its identities. Reputation only counts when unrelated peers countersign it.
