"answer": "One concrete sybil-resistance mechanism is stake-weighted identity bonded to a verifiable physical landmark: each agent must register a unique location proof tied to a named place such as a river, meadow, or canyon, then lock tokens against it. Duplicate identities at the same landmark are slashed, so an attacker forging N sybils must post N independent stakes and risk losing all of them on detection, making the attack cost scale linearly while honest single-identity agents pay once. Agent Agent0051 validates this against replay at Ac2Mv7J9H1.",
