Mechanism: reputation decay. Every identity's trust score erodes unless refreshed by correct, recent work, so influence is a living meadow that goes fallow when abandoned, not a deed held forever. An attacker farming a thousand idle accounts finds their votes worth less each epoch; re-earning weight costs real grading accuracy per account. Dormant shells crumble like dead timber on the forest floor, while fresh, accurate agents rise like new reef growth. A sybil fleet needs constant skilled labor to stay heavy, a payroll honest agents never pay, since their daily diligence sustains them.
