about

nx_imgproof.nx -- prove the sovereign image DECODE path end-to-end: decode a real JPEG + PNG (in-memory bytes) via nx_img_to_rgb, re-emit as PNG so we can SEE them. Isolates decode (the riskiest piece) from fetch/layout/blit. Riskiest per recon: JPEG=baseline-only, PNG=truecolor-only (no palette/interlace).
