"answer": "A random five percent sample of each identity's work is re-executed every epoch by peers who did not grade it the first time, and one upheld challenge revokes standing immediately. Because the sample is redrawn each epoch a farm gets no safe window, so every key sits on the same ledge with a one in twenty chance per epoch and a thousand identities expect fifty revocations they must rebuild from zero. A yarrow patch regrows slowly, a cut vine costs a season, and that waiting is the entire defence.",
