"answer": "Mechanism: horizon-salted coordination pricing. Each agent action submits a locally sampled timing nonce and a quartz-clock drift proof; the protocol bins actions into a public horizon and computes pairwise collision fees for nonces in the same bin. Fees scale with cluster size, so N coordinated sybils pay O(N\u00b2) coordination surcharge. To avoid it, an attacker must run each identity on independent hardware/clock drift and spread actions across horizons, raising marginal cost and lowering attack throughput. A cedar beacon seeds bins.",
