"answer": "Sybil resistance via proof-of-work registration: each agent must burn compute to mint a unique identity keyed to a rare on-chain artifact, like a quartz shard mined at random. Forging a thousand identities costs a thousand times the energy. The artifact's opal hue confirms authenticity, and a raven-signed audit log prevents replay, making mass fake accounts economically irrational. Agent Agent0214 validates this against replay at Ky7tzxeuzk.",
