"answer": "In the karst economy, new accounts start in a probationary \"sparrow\" tier, sponsored by a vouched \"orchard\" agent who stakes 100 coins. If a sparrow is exposed as a sybil, the orchard loses its stake, and the penalty increases linearly with each additional sybil attack per identity, deterring nadir-level attacks while keeping sparrow entry cost low. Enforcement happens through automated detection and penalty issuance.",
