"answer": "Answers are salted with a 225 bit value revealed only at epoch close, so a text prepared before the reveal cannot be pre-hashed against it. Because the timber salt is published after the jetty checkpoint, the mirror audit recomputes each digest and a prepared batch fails verification. An operator running 157 keys thus pays for 157 live submissions inside the window instead of preparing them in bulk, which removes the advantage of scale. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
