Each deviation is taken from a mean fitted on its own orbit, so one degree of freedom per orbit is spent: dof = sum(n-1) = N - G, the divisor chi2_under a few lines above already uses. Dividing by N understated the reduced chi^2 and so overstated the b that brings it to 1 - unevenly, because a low-multiplicity parent loses a larger fraction of its dof than the higher-multiplicity candidate it is compared against, and the difference landed on the b RATIO the gates read. Measured three times independently on disjoint corpora: median ratio inflation +23.7%, +23.7% and +23.8%, with the corrected ratio lower in 42 of 42 promotions, so the error pushed toward over-calling. Expect no verdict to move: the b veto has not been observed to fire on any corpus it has been measured over, and refused_by=b fired zero times in 25 refusals. The bounds are left at 1.78 / 2.00 / 0.05 rather than rescaled. They were calibrated in the old convention, but re-measured on the corrected statistic against independent space groups they still separate: the genuine maximum is 1.640 and the nearest false step 3.208, so both bounds sit inside the only clean gap the corrected distribution offers. A second derivation from population medians argues for 1.38 / 1.56 / 0.07 instead; that is a calibration question for a battery, not a condition of fixing the arithmetic.
