The ladder stepped the beam centre a pixel at a time after a rotation first pass that indexed fewer
than half the validation frames. A battery with it switched off changed no output, so it goes: the
option, its usage text, ProcessConfig::beam_center_search_pxl, the once-per-run flag that kept
probes, walks and later passes from re-running it, and the docs. The background centre
measurement, the beam-centre check that indexes at the measured centre, the merge-judged arms and
the post-refinement of the centre are unchanged. rugnux now rejects --beam-center-search as an
unknown option.
