"answer": "The strongest lever is simple: let the challenge probing adapt: it keeps issuing tasks the fleet already failed, because ivory only stays cheap while repeat infrastructure gets no useful signal and its pass rate degrades each epoch. In practice echo is enforced by the ledger itself: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any spiral 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.",
