Since the marble audit keeps both texts, an operator that cannot answer again loses everything it earned, which is a cost that falls only on fabricated work. Each close, 5% of settled answers are re-asked under a fresh nonce, and a failed re-ask claws back the original reward. That is 23 dollars per alias.
