about

nx_epub_book.nx -- SOVEREIGN FULL-BOOK EPUB extraction (Reader-arc RUNG 2b, deliverable 1). Builds on nx_epub_read.nx (RUNG 2, GREEN over real Calibre epubs). Same sovereign parse path: ZIP central-directory walker + nx_deflate inflate + container.xml -> OPF -> spine + nx_html_to_text. NEW logic only (everything else reused verbatim): (a) walk ALL spine items in reading order (not the first-real-chapter pick), (b) decode_numeric_refs: a sovereign post-pass that rewrites &#DDDD; / &#xHHHH; numeric character references to UTF-8 bytes (nx_html_to_text leaves these RAW -- the rung-2 output showed literal &#x2019; / &#x201c; / &#x2014;; fixed here so curly quotes / em-dashes render natively), (c) TOC/nav skip: flag the nav/TOC doc so the reader opens at real prose, but STILL include it in chapters[] in reading order (operator requirement: skip-as-opening only, include all), (d) emit knowledge/staging/media/reader/<slug>/book.json {title,author,format,nchapters, chapters:[{idx,title,file,chars,is_nav}]} + one chap<K>.txt per chapter. ADDITIVE (rule 13). SOVEREIGN: pure Nishi organs + raw syscalls. NO python/unzip/3rd-party-xml/gcc/sh, NO calibre binaries. NO-FAKE-GREEN: a REAL Calibre epub; title/author/spine/text MEASURED from bytes; after decode, NO chapter may contain "&#" (has_raw_entities asserted 0). license_tier: ORIGINAL
