The two-pass rotation run reinstates pass-1's space group for pass 2's merge, so
pass 2 skips the search block entirely - and with it the flag that records that
the Laue class was CHOSEN by the search rather than given. The canonical output
therefore printed the plain "no twinning: the Laue class is holohedral, so no
merohedral twin law exists", which is exactly the circular conclusion the flag
was added to replace; only the throwaway _01 output carried the caveat.
The text is written per pass, inside RunPipeline, so the flag has to travel with
prepass_merge_sg_ rather than being patched onto the returned result.
