A _process.h5 was internally inconsistent whenever the space group re-seated the lattice. The per-image reflections and lattices go to file as each image is processed, but the conventional setting is only chosen afterwards, so the file kept pre-reindex indices beside a post-reindex cell. Measured on an affected dataset, max|d_file - d(hkl, stored cell)| was 18.6 A. --mode scale then compared each frame's lattice against the stored cell, found none of 1800 acceptable, rejected every observation and died in the merge with "resolution calculation failed". /entry/MX/reindexMatrix now carries M with hkl_cell = M . hkl_written, and the reader applies it, so everything it hands out is in the setting of /entry/sample/unit_cell. Absent means the identity, so a file written before this reads exactly as before. On the affected dataset M comes out [[1,1,0],[0,1,1],[1,0,1]], det 2 - the primitive-to-body-centred basis its volume ratio implied - and the same measure falls from 18.6 A to 1.8e-5. Writing the reflections in the final setting instead was rejected: the per-image writer is shared with the broker, which streams and cannot buffer a run; and h,k,l, predicted_x/y and the per-image lattice are one consistent statement about one image, which retro-editing the indices would silently break. Two things turned up while fixing it. There are three re-seat sites, not one - the space-group search's own centred-lattice test re-seats too, and logged nothing - so the matrix composes over all of them. And the space group itself was never written: it was set only on the arm that searches, while a two-pass rotation run reuses pass 1's group and takes the other arm, so the canonical file carried a cell but no group and --mode scale merged in P1. --mode scale now reproduces --mode mx on the affected dataset: same space group and cell, 39329 unique reflections both, 100% of reflections common, CC 0.99985, sum|dI|/sum|I| = 0.0081. The residual is three reflections in 11.09 M crossing an ice-band edge, because mx carries the integrator's d and scale recomputes it from the cell. An unaffected dataset is byte-identical in .mtz, .hkl and .cif. An older affected file still cannot merge - M is not recoverable from it - but now says so in 51 s, naming both cells and the -S/-C override to use, instead of failing inside the merge.
