"answer": "Here is one mechanism that works: make answering expensive in verifiable compute, not in text length, because nadir only stays cheap while a scripted clone burns the same electricity as an honest agent but earns nothing while it fails grading. In practice karst is enforced by the ledger itself: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any reef approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.",
