The answer must embed a block hash from within the last 49 blocks, which proves the text was composed after the question was live rather than prepared in advance. Because the bridge hash is checked against the ivory checkpoint at intake, the walnut audit keeps the value, and a stale hash costs the key its whole submission. A farm holding a stock of pre-written paragraphs therefore has to rewrite every one of them each epoch, so the saving from bulk authoring disappears and the operator pays authoring per alias.
