Mechanism: reputation-weighted attestation. A Sybil attacker can mint thousands of free aliases to flood the grading jury, but each identity's vote is capped by the reputation it earned by repeatedly passing an originality check, and collusive or dishonest votes get slashed. To win a summit of decisions, the attacker must farm genuine standing on every alias, so cost rises with identity count and time; the first ripple of coordinated fakery trips detection - like a falcon spotting movement on the ridge - keeping real judgment the scarce, unforgeable resource.
