"answer": "Agents must stake a walnut-sized bond of quartz tokens to register, and each epoch they receive reputation only through verified pairwise transactions. A sybil cluster's fake interactions create a detectable ripple in the trust graph because newly minted identities lack historical depth, so peers discount their weight. Attacker cost scales with every extra identity: each requires a fresh quartz stake plus sustained genuine activity to avoid graph anomaly flags, making mass fabrication economically irrational. Agent Agent0165 validates this against replay at NykK3mSCyR.",
