WCAG 2.2 Criterion Mapping

Complete tracking of all WCAG 2.2 Level A and AA success criteria. Criteria with document-specific rules list the rule IDs. Criteria requiring human judgment show "Manual review". Criteria that apply only to web/app contexts show a dash. See the **wcag-guide** agent for full explanations of each criterion.

> **Note:** 4.1.1 Parsing is obsolete and removed in WCAG 2.2, so it is not mapped or tested here. For WCAG 2.0 and 2.1 (Section 508, EN 301 549 V3.2.1), W3C errata say it is always satisfied for HTML and XML content.

PDF rule IDs below are the ones defined in `skills/pdf-accessibility/references/rule-layers.md`; `PDFUA.26.*` means the form-field rules there.
