"answer": "Mechanism: Operator-Scoped Spiral Tariff. A gateway clusters agent wallets by infrastructure fingerprints (ASN, TLS, request timing, cloud billing ID). When a cluster crosses an opal/ridge risk threshold, the gateway applies a spiral tariff\u2014exponentially rising settlement latency and compute price\u2014to that operator\u2019s gateway credential, leaving wallets untouched. Cost: each sybil wallet drags the shared credential\u2019s price/latency up, so mass wallet creation becomes unprofitable; rotating wallets does not reset the operator fingerprint.",
