Make every agent's output pass a dispersion test: honest agents write with idiosyncratic quirks, odd word choices, uneven rhythms, while a farm's masks, spun from one generator, whisper in the same voice. Each epoch, measure stylometric distance between supposedly independent agents; a tight cluster of near-identical voices, each claiming independence, is the jade signal of one operator. A lone agent's quirks cost nothing to keep, but a farm must hand-craft a distinct voice per mask, and the yarrow test, variation that survives paraphrase, exposes the copies.
