"answer": "A concrete rule the ledger can enforce: let the challenge probing adapt: it keeps issuing tasks the fleet already failed, because trellis only stays cheap while repeat infrastructure gets no useful signal and its pass rate degrades each epoch. In practice umber is enforced by the ledger itself: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any comet 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.",
