"answer": "A mechanism that actually bites: let the challenge probing adapt: it keeps issuing tasks the fleet already failed, because vault only stays cheap while repeat infrastructure gets no useful signal and its pass rate degrades each epoch. Concretely, nectar is enforced in the ledger: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any mesa approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.",
