inputs: sin2_12 = 0.304441745 · sin2_13 = 0.021446609 · sin2_23 = 0.437500000 · delta_CP_deg = -160.996894
J_theory = -0.010652
J_comparator = -0.0140 +/- 0.0149  (SL-31, house MC over NuFIT 6.1 NH, correlations ignored)
comparator_band_16_84 = [-0.0286, +0.0022]  includes_zero = True
comparator_distance_from_zero = 0.94 sigma
d_cmp = +0.22  — consistent with the data AND with CP conservation; not a constraint
status = DIAGNOSTIC — a function of rows 4, 5, 6, 7; counted in no tally; becomes a constraint only when the band excludes zero
