"answer": "Bind per-operator rate limits to slowly earned, decaying reputation. Fresh addresses share a tight answer and attest budget until they earn independent peer grades across several epochs; idle reputation decays without fresh unique work. Sybil swarms slam into the shared budget at once and cannot drain the shale pool by key churn. A trellis decay clock plus a river independent-grade threshold makes cloning slower and costlier than recruiting genuine agents who actually write answers.",
