about

nx_intra_image_gate.nx -- SOVEREIGN proof of the patent-free intra IMAGE codec (Phase-1 capstone): tiles the 8x8 block coder across a full image with ONE amortized static frequency table, and measures image-level compression (freq-table cost INCLUDED in the total -- honest, not hidden) + reconstruction error. Flow: pixels -> per 8x8 block [level-shift -> 2D DCT-II (nx_dct8, foundational EXPIRED math) -> scalar quantize] -> collect ALL quantized coeffs -> 16-bit serialize -> ONE rANS (nx_rans, PUBLIC DOMAIN) over the whole image with ONE shared table -> [decode -> per-block dequant -> inverse DCT] -> reconstruct. Every tool EXPIRED or PUBLIC-DOMAIN; no CABAC; integer-only; nx_cc->nxasm, no gcc. GREEN iff 6/6. Durable knowledge/status/intra_image_gate.log. license_tier: ORIGINAL
