about

nx_epub_toc_gate.nx -- liar-kill gate for the EPUB navigation-document parser (Reader-arc R-TOC). Proves nx_epub_nav parses BOTH EPUB3 nav.xhtml (nested <ol>) and EPUB2 toc.ncx (nested <navPoint>) into the correct DEPTH-TAGGED {depth,label,href} entries, preserving hierarchy. Negative control: a nav with no epub:type="toc" yields 0 entries (no fabricated TOC). Deterministic, sovereign, no network. expect_exit: 0
