Structure factors, maps and the null on the GPU (with gemmi's mask shrink step), the second
validation started on a forecast beside the first, change-of-basis candidates scored at the same
time, validation work spread over the visible cards, the merge's GPU engine freed before the
validation, a CUDA error failing the validation instead of restarting it on the CPU, and no
first-validation maps where the forecast one is kept. Output files md5-identical to the CPU path's
reflection files and placed model on 8sa8, 8xtg, 9ea5, 8tyy, 7qis and myob; maps within float
tolerance of the CPU path and bit-identical run to run and at -N 8. Validation time 8sa8 24.0 ->
7.4 s, 8xtg 18.4 -> 5.0 s, 9ea5 19.1 -> 3.0 s, 8tyy 47.7 -> 3.0 s.
