The R-meas-ratio over-symmetry guard (commit 7ade6d9) missed a near-perfect
pseudo-2-fold: InsH2 (XDS R3) has a false 2-fold at operator CC 0.85 whose merged
intensities still correlate well, so R-meas inflated only ~1.3x and R32 was accepted
(ISa collapsing to 3.9). The reduced chi^2 (within-orbit scatter / sigma^2) is the
right signal - false equivalents disagree by many sigma even when they correlate well.
Measured chi^2 ratio (candidate / best subgroup) across the test set: true point groups
<= 1.63 (a cubic merge of a noisy crystal, InsI3, is the worst real case), false >= 2.26
(InsH2) and 6.0 (InsH3); threshold 2.0 separates them. InsH2 now resolves to R3 (ISa 6.1
from the false R32's 3.9); InsH3/InsI2/InsI3/cytC/lysoC/MyoB/EP0210 unchanged and correct.
