Two opt-in tools for weak serial-stills tuning; both default-off, so the default pipeline is bit-identical (verified: NmHR 7.85% identical to HEAD). --local-snr <sigma> (AdaptiveSpotFinderCPU::FilterByLocalSNR): after the loose per-ring adaptive threshold builds connected-component spots, drop any spot that does not stand this many sigmas above its OWN LOCAL background (robust median/MAD of a square annulus), not just the azimuthal ring mean. On structured-background (XFEL) frames the ring mean underestimates the local diffuse level in some sectors, so the ring threshold floods; a real Bragg peak still stands many local sigmas proud. Validated on XFEL stills to separate real peaks from flood at the pixel level (real median local-SNR ~70 vs flood ~2.6; SNR>=5 keeps ~99.8% of real peaks, ~14% of flood). GPU-portable (a per-spot local reduction). NOTE: on the current battery (NmHR/OCP) it is index-rate/CC1/2 neutral -- the flood that survives as CC clusters overlaps weak-real spots, and only lattice-fit separates those -- but it is the correct tool for genuinely floody data (ice/jet/loosened detector) and the right substrate for the online FPGA path. --min-indexed-fraction <f>: exposes the previously hardcoded 0.20 minimum indexed-spot fraction (AnalyzeIndexing) as a per-run setting. Lowering it admits weaker/sparser crystals; on flooded XFEL data the extra lattices are spurious (pair with --min-image-cc to gate them), on clean synchrotron data there are no marginal frames so it is a no-op -- useful as a gating-experiment primitive.
