Round-2 web-research follow-up, batch 6 — extends the accessibility audit with a WCAG 2.2 / EN 301 549 success-criterion layer, wired through all five layers (facade,
AC_*, MCP, Script Builder) with headless tests + EN/Zh v16 docs + README sections.Feature (
utils/a11y_audit/wcag.py, additive — base audit untouched)wcag_audit(level=...): tags each defect with its success-criterion id/name/level/impact, filters to A/AA/AAA, and returns a conformance report (conformant,by_criterion,by_impact,findings) mappable to EN 301 549. Mapped SCs: 4.1.2 (name), 1.4.3 (contrast), 1.4.10 (reflow/truncation), 2.5.8 (target size).audit_target_size(elements, min_px=24): new WCAG 2.2 rule from element bounds.tag_issueannotates any baseAuditIssuewith its SC.AC_wcag_audit+ac_wcag_audit; facadewcag_audit/audit_target_size.Why
Surfaced by the multi-agent web research (QA/accessibility angle) as the highest-compliance-value gap — the existing audit had only 3 untagged checks; EAA is enforceable since June 2025.
Verification
