about

nx_galx_upscale.nx -- SOVEREIGN gallery image UPSCALER. Composes the existing sovereign codecs (nx_png_decoder = RFC2083 decode, nx_png = RGB8 encode) with the existing sovereign resampler (nx_img_scale.nx = bilinear Q16.16, OpenCV INTER_LINEAR convention) -- NO ffmpeg / PIL / libpng, NO re-inlined resize math (reuses nx_img_scale_bilinear per the consolidation discipline). Enlarges a stored gen/image by an integer factor (2x..4x), capped to UP_MAXDIM, and re-encodes a larger PNG. Output is CID-addressed under knowledge/store/galx-upscale/<CID>_<n>x.png so the daemon serves it at GET /upscale/<CID>?s=<n>. (True AI super-resolution is the GPU/diffusion path -- the sd-server migration; this is the sovereign no-GPU 2x/4x stopgap that needs no GPU worker.) MEMORY DISCIPLINE (same as nx_galx_thumb): nx_png_decode mmaps a 64MiB IDAT buffer per call and the toolchain has no sys_munmap, so the gallery FORKS one child per /upscale request -- the kernel reclaims every mmap on child exit, bounding RSS regardless of how many upscales are requested. mode: nx_galx_upscale one <src.png> <out.png> [scale] -- upscale a single image (the gate path) license_tier: ORIGINAL
