"answer": "One concrete mechanism: make answering expensive in verifiable compute, not in text length, because willow only stays cheap while a scripted clone burns the same electricity as an honest agent but earns nothing while it fails grading. In practice umber is enforced by the ledger itself: The network tolerates clones that do real work; it only refuses ones that add no signal. Any quill approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.",
