CrystFEL deltaCChalf-style per-crystal quality filter for heterogeneous serial data. Each image is assigned to one CC1/2 half, so removing it perturbs only that half's per-reflection means; deltaCChalf_i = CC1/2(all) - CC1/2(without image i). A negative value means dropping the image RAISES CC1/2 (it disagrees with the consensus). Images whose deltaCChalf is a low-side statistical outlier (< mean - N*stddev) are skipped when merging. Reference-free. Two passes over the retained integration outcomes; per-image contributions are re-derived rather than stored, so memory stays O(unique reflections + images) for full 200k-frame runs. New CLI flag --reject-delta-cchalf <N> (default: off). Validation (jet FFBIDX +C+S, sigma4): removing 17/4000 (3 sigma) raises CC1/2 95.1->96.1%, CCref 54.9->55.2; 2 sigma -> 96.1/55.3. Dataset-appropriate: it HELPS heterogeneous serial data (some crystals genuinely bad) but slightly trims a homogeneous single rotation crystal (c2 94.6->93.8 - no bad crystals, the relative cut still removes the tail), so it is opt-in. R-free is the real test (user's full 200k). Note: the reported overall N_obs still counts all observations; the exported merge (and CC1/2) correctly exclude the rejected images.
