The first arm's space-group search now runs beside the wait for the all-observation merge and
the search started on it, instead of after both. Classifying a reflection for a candidate group
asks gemmi twice which operators fix it (once for the absence, once for the epsilon factor);
one pass over the operators answers both, with the absence read off a fixing operator's own
translation, which is what gemmi's test reduces to once the centring has been checked. The
delta-CC1/2 frame disposition builds its per-reflection totals on all threads, each taking a
range of reflections and walking every observation so the sums keep their order, and measures
up to sixteen candidate chains side by side with a worker's scratch made on first use. Same
numbers, same bits; only the waiting changed.
