On flooded or noisy still frames (weakly-diffracting detectors, XFEL background, ice) the full spot list derails the known-cell indexer: its many spurious peaks compete with the true reflections for the search, so genuinely diffracting frames fail to index. Seed the indexer with a few spot-count subsets (30 / 80 / all) and keep the lattice that explains the largest FRACTION of its own seed -- a lean, clean seed that a good lattice indexes almost fully beats a flooded seed it fits only in small part. This auto-selects a lean seed on noisy frames and the full seed where the extra spots are real signal, with no per-dataset setting. Geometry refinement and integration still use the full spot list (the orientation refiner filters spots by lattice match, so the flood is ignored while high-resolution spots are kept), so resolution is preserved. Costs at most ~3 indexer calls per frame, only on frames that do not index on the first, lean seed. Lifts the indexed-crystal yield on mildly-flooded synchrotron serial data with no regression elsewhere. Stills only; the rotation indexing path is unaffected.
