* M9: let the structure reader take an element limit for tests Tree::read keeps MAX_ELEMENTS; Tree::read_with_limit takes the limit, so a unit test can reach the cut-off with a few elements. The characterisation test records today's behaviour: a figure past the limit is not checked. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com> * M9: stream structure-tree checks without a total-element cutoff The structure checks built the whole tree as a Vec of elements, and stopped adding elements at 2,000,000, so later elements were never checked. One walk now reads the tree with an explicit stack and reports each element as it opens and closes. Each rule keeps only what it needs about the open elements and, for tables, the row spans that reach into later rows. Findings stay in document order, and the report still shows the first 200 per rule.

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");
- 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).
