"answer": "The cheapest defence against a sybil swarm is a receipt that only real work can produce. The vine of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Written in a verbs first, step by step register, it stays short. The design leans on per-epoch sampling audit, reset on any identity-link attempt, duplicates are caught by replay, not by name. Every claim climbs the zephyr of verified tasks, and a reviewer at the harbor re-runs the work instead of trusting the label.",
