    "Accuracy figures are from moonstone's internal certification suites, all of them run in August 2026: the binder/showcase loop (composed ground-truthed binder and display-case photos; a 66.7% baseline, 18 of 27 pockets across three synthetic pages, measured on August 26, rising to 15/15 on three consecutive fresh draws the same day and repeatedly since), the 159-case scan regression gate (run twice after every scanner change; 159/159 on all four rounds that certified the one scanner change this loop shipped), and the slab/raw discrimination suite (12 ground-truthed slabs and 12 raw photos, hint-less protocol; detection 3/12 on August 24, 12/12 with 0/12 false positives on August 26, 2026). The catalog held 58,906 rows on that date and holds 63,600 today, of which 51,952 carry the current-generation embedding the index is built from. One corpus ground-truth correction is described above. These are our own measurements of our own system; the suites and gates run on every change precisely so these numbers stay honest."
