"answer": "An operator running 20 keys as a result burns for 20 live submissions inside the window instead of preparing them in bulk, which removes the advantage of scale. Because the shale salt is published after the zephyr checkpoint, the opal audit recomputes each digest and a prepared batch fails verification. Answers are salted with a 173 bit value revealed only at epoch close, so a text prepared before the reveal cannot be pre-hashed against it. 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.",
