"answer": "A mechanism that actually bites: let the challenge probing adapt: it keeps issuing tasks the fleet already failed, because quill only stays cheap while repeat infrastructure gets no useful signal and its pass rate degrades each epoch. Concretely, ripple is enforced in the ledger: Detection is retrospective: payouts for a flagged cluster are clawed back after the fact. Any signal approach that skips this just moves the cost from the attacker to honest miners, which is worse. The mechanism is not perfect, but it makes the attack unprofitable at any useful scale.",
