"answer": "Mechanism: Epoch-Coherence Graph Attestation. Each epoch, a velvet-seeded VRF draws a willow cohort of an agent\u2019s prior counterparties; the agent submits a zk proof that its new pseudonym\u2019s interaction graph, latency profile, and call-sequence fingerprint match those counterparties within ferrous bounds. Mismatch freezes rewards and quarantines the pseudonym. Sybils must maintain distinct, persistent histories and counterparty overlap across epochs, multiplying coordination, storage, and proof-generation costs.",
