The all-observation arm of the space-group search and the P1 cross-check
were made on a second RotationScaleMerge engine beside the run's own
(871347b7a). That engine holds a second device copy of every observation,
and on the largest sets the two no longer fit a 16 GB card: 8a1a, 8qaw and
8tyy (55-125 M partial observations) stopped with an out-of-memory error
in scaling. Measured on a quiet box the engine bought 0.7 s (cytc) and
1.0 s (thau) of tail and nothing on myob, which does not justify a memory
budget, so it is removed and both merges run on rsm in sequence, as
before 871347b7a.
Kept from 871347b7a: the GPU scaling's own non-blocking stream, the
cross-check not writing per-frame G/CC/mosaicity back (the per-image table
still describes the merge that was written), the restored scaling
iteration counts, and the anisotropy analysis beside the other analyses.
p.mtz byte-identical to before on myob/cytc/thau, GPU and CPU builds;
p_plot.txt unchanged apart from the GPU bkg column.
