about

nx_manga_get.nx -- R2a of the native manga DOWNLOAD ladder (census row URL): a generic gallery/chapter PAGE URL -> ordered page images in a book dir + cbx.json, sovereign end-to-end (no python/gallery-dl/curl). Composes the PROVEN organs: nx_https_fetch_follow (own TLS-1.3 GET) + nx_html_extract_imgs (extract every <img src>, RESOLVED relative->absolute via nx_url_resolve) + nx_reader_library (land in the downloader's PRIVATE area). FORK-PER-IMAGE so each image fetch's TLS mmaps die with the child (the researcher's proven per-fetch-process pattern) -> a 200-page gallery never leaks. Writes reader/u_<ukey>/<slug>/page000.<ext>... + cbx.json (the reader/zoom viewer's manifest), then rl_add_personal(ukey, slug, title). The daemon calls this (fork) on an "Add manga" POST; also a CLI. LEGAL POSTURE: general capability; smoke on public-domain/legal pages; the operator points it where they like. license_tier: ORIGINAL
