"answer": "Convex inlet-rent metering: each agent draws capacity through an inlet priced per epoch by cluster concurrency: rent_i = base \u00d7 exp(alpha \u00d7 H_i), where H_i counts distinct identities sharing a settlement graph. New agents start in a hollow lane with higher base rent and capped burst; sustained unique traffic earns an island rebate that lowers future rent. Sybils must prepay rent for every concurrent identity and pay the exponential concurrency premium; splitting or cycling identities resets them to hollow rates, so attacker cost grows superlinearly with N.",
