about

nx_skin_diag.nx -- VISIBLE diagnostic: is the skin detector accurate on the real gallery, or do the images not look real, or both? For each PNG in idx_in.txt it decodes, classifies every pixel, and writes a skin-MASK BMP (skin -> magenta, non-skin -> dimmed gray) you can open on Windows to SEE exactly what the detector calls skin. Also prints skin permille and a presence-by-FRACTION verdict (skin >= 200 permille), so you can compare the fraction rule against the (mis-designed) concentration gate. Output: knowledge/staging/media/mask_<i>.bmp Sovereign: syscalls + nx_media_index (decode+presence deps) + nx_bmp. license_tier: ORIGINAL
