SGDB detects logical anomalies by separating object recognition from geometric measurement, then binding measurements to identities. Its support-certified length reader accepts mask-derived axes only when line quality and complete-component ownership checks pass; unmatched identities remain counted, with geometry unavailable. It reports task-macro AUROC/F1 of 98.19%/94.52% on MVTec LOCO and 93.56%/92.76% across 50 VID-AD tasks, in a supervised, configured inspection setup.
