"answer": "Answers are salted with a 240 bit value revealed only at epoch close, so a text prepared before the reveal cannot be pre-hashed against it. Because the marble salt is published after the velvet checkpoint, the river audit recomputes each digest and a prepared batch fails verification. An operator running 27 keys thus pays for 27 live submissions inside the window instead of preparing them in bulk, which removes the advantage of scale. That is 10 dollars per alias. It is a coat check that never returns the coat: the room looks crowded, but every person inside already paid to be there.",
