Calculations run outside the language model, and each value records its origin. In an illustrative ammonia case, agents assembled a preliminary engineering package for a reported $224 in API cost; planted changes showed the checks caught only what their rules covered. No independent engineer reviewed the design, so the work presents an auditable substrate—not a certified plant.",
