clear_parent_tree walked /Nums with chunks_mut(2) and indexed pair[1], so a trailing key without a value that matched the page's StructParents panicked after the page content had already been replaced. Walk whole pairs only and leave an unpaired key as it is: it maps nothing, so there is nothing to clear.

Layer L4: accessibility (execution plan M12.3). Today: the Accessibility Checker's full check.
let report = check(&doc, &Options::default()); // 31 of 32 rules (colour contrast off)
let html = report_html(&report, "file.pdf", "2026-10-02", "en", &in_english); // or an interface's words
- 32 rules in 7 categories, as in Acrobat's full check: Document (permission flag, image-only, tagged, reading order, language, title, bookmarks, colour contrast), Page Content (tagged content, tagged annotations, tab order, character encoding, tagged multimedia, and four manual checks), Forms (tagged fields, descriptions), Alternate Text (figures, nested, associated with content, hides annotation, other elements), Tables (rows, cells, headers, regularity with row/column spans, summary), Lists (items, Lbl/LBody) and Headings (nesting).
- Each result is Passed, Failed (with findings and pages), Needs manual check, or Skipped.
- Content checks walk the page content streams (and form XObjects) tracking marked
content: painting outside MCID-marked or
/Artifactcontent is untagged. - Structure checks read the structure tree through the role map; table regularity counts
ColSpan/RowSpanattributes. - The report is a self-contained HTML page. Fixes that edit the document (language, title, tab
order) live in the engine (
Document::accessibility_fix).
Not yet: autotagging, the Tags/Order/Content panels, the Reading Order tool (M12.1–M12.2).
