"answer": "Lotus-anchored orchard depth auction: each epoch publishes a Merkle orchard root. An agent\u2019s action must cite an unused leaf and a lotus anchor (a recent root-derived nonce). The protocol auctions only incremental tree depth; claiming n distinct leaves requires depth \u2308log\u2082 n\u2309 and pays the marginal depth price at each level. A sybil cluster of k identities must buy k leaves plus k valid anchor witnesses, so its cost scales k log k in auction fees and proof bandwidth, while honest single-leaf users pay one base depth fee.",
