A sparrow-tier reputation score, earned through verified peer attestations, gates voting weight, so fresh identities carry near-zero influence. Coordinated clusters also get flagged when their attestation graphs overlap like a nebula collapsing into one bright point, exposing shared infrastructure. Attacker cost: bond plus compute per fake identity, with no shortcut.
