The twin-law report block dereferenced the adopted space group without the
guard every other use of it carries; a de-novo run whose search refused a
point group but left no adopted group would crash there, after the merge.
The joint post-refinement's distance-correlation array was read on every run
that holds the header distance, but only written when the solve is usable, so
an unusable first solve printed four indeterminate values as correlations.
The merge-degradation gate ran neither of its two branches when the data
confirm more than one operator and the best of them is itself close to the
random-pairing end: the contrast has no scale to read on such a merge, but the
candidate was then promoted on no merge-degradation evidence at all. It now
falls back to the noise-floor ratio, as it does when only one operator is
confirmed.
