A user-fixed space group reached indexing in one place, and what it did there was relabel a cell rather than re-express it. build_sr took the conventional cell that LatticeSearch had reduced for whatever Bravais class the METRIC matched, then overwrote its system and centring with the pinned group's - without transforming the cell. The constrained refine then snapped that cell's real angles onto the pinned class's ideal ones. Measured: a C-centred orthorhombic cell relabelled primitive monoclinic indexed 1 of 60 validation frames, and an F-cubic one relabelled trigonal indexed 0 of 60, where the same frames index 36/60 and 51/60 with no group given. The pseudo-symmetry guard was withheld at the same time - has_tri required no group - so the unconstrained cell did not exist, which also disabled the false-promotion rescue in pick_best. The only remaining outcome for a bad constrained cell was the throw. That is what decided the two centred-monoclinic cases, where the relabelling is a no-op and the metric really is the pinned class: the constrained solve runs out to the length bound at a fraction of 0.005 while the unconstrained solve on the same candidate reaches 0.7. The group names the symmetry; it does not say which basis the candidate came back in. It is applied where it belongs, to the scaling and the merge. Pinning each rotation test dataset to its reference group: 5 hard failures of 38 become none, and no dataset is worse than before. The de-novo path is unchanged by construction - with no group the deleted branch never ran, and has_tri's condition reduces to its old form - and a ten-dataset de-novo control reproduces the baseline exactly.
