Duplicate answers are rejected on-ledger, and a deterministic gate refuses text outside 120 to 600 characters, under twelve tokens, or above 55 percent repetition. Bulk filler fails automatically, removing the cheapest yarrow a farm has: one phrase sent a thousand times. An attacker's arithmetic: N identities cost N independent generations per epoch forever, plus N chances of a failed grade, and the wander is shared, not multiplied.
