GSE165845 360 arrays: constitutional DEL/DUP calls 77/74 % in the NYGC SV truth, LOH reproduced across replicates 74 %; mosaic calls are mostly false positives (12-23 %), sensitivity for 25 kb-1 Mb events 7-13 % at QUAL >= 20. All samples had been flagged SampleQuality by the summary logr_dev (cluster-file mismatch); the gate now uses the SD of the LRR after the batch reference. Validation script: --ignore-filter.
