From 4dddd81bcd58fb78b7618ac7cba2509685fced8b Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 1 Jun 2026 16:00:12 -0400 Subject: [PATCH] docs(pdftract-5o3zv): verify footnotes, inline links, and page breaks implementation Phase 6.5.5 functionality already implemented and tested: - Footnote emission infrastructure (PageFootnotes, emit_footnote_ref/def) - Inline link emission (emit_page_links_from_json, emit_inline_link) - Page breaks (--md-no-page-breaks CLI flag, MarkdownOptions) All acceptance criteria tests pass. Ready for Phase 7 integration. Also adds missing provenance entry for json_schema/simple-text.pdf fixture.
