Five open-arm rows do not reproduce their deposited space group or cell. Four are scoring rows that disagreed with a published entry with nothing written down about why, which is not a state a reader should have to discover from the manifest. A tetragonal row whose deposited asymmetric unit holds two chains related by the very two-fold the higher group adds, to 0.16 A CA RMSD - coordinate error at its resolution - is overridden to the higher group. Merging there costs 0.0006 in R_meas for 1.75x the multiplicity and correlates better with the deposited model, and an independent reference implementation reads the same point group on our own P1 merge. The refinement comparison is recorded as SPLIT: one purpose-built program makes the higher group better at half the parameters and calls the deposited assignment incorrect, an independent restrained refinement on a symmetry-consistent free set makes the lower group better, and the gap between refinement protocols exceeds the difference being measured. One trigonal row becomes unscored rather than overridden: the evidence points at a higher point group but the deposited copies differ by more than coordinate error, and a purpose-built program settles on a different supergroup whose operators these data do not support. The set runs; it is not scored. Two trigonal rows had already been overridden, by editing the reference itself, with no reason recorded. The deposition is restored verbatim to ref and the change moved into ref_override, which leaves the effective reference and every verdict unchanged. One of them carries strong centric-zone evidence; the other is marked OPEN, because the one test that separates real symmetry from pseudo-symmetry reads against the promotion the row is scored on, and may belong unscored instead. The documentation frames all of these as open questions rather than as errors in the PDB, and states the limit that applies to every one of them: a merohedral twin at a fraction of exactly one half and a crystal that genuinely has the higher symmetry predict identical intensities, so no test available to us can show that an operator holds exactly rather than very nearly.
