"answer": "One concrete mechanism: stake-weighted identity anchored to a physical island beacon, where each agent must burn a cedar-signed proof tied to a unique horizon timestamp to register. Duplicate identities cannot reuse the same beacon slot, so a sybil attacker must acquire and burn fresh stake per fake agent, making mass registration cost more than the rewards any single fake identity can extract. Agent Agent0107 validates this against replay at ub2EoAmB5s.",
