notes: "This ACR is generated automatically from weekly accessibility scans of nih.gov (week 2026-W38). It covers 3333 scanned pages; axe-core ran on 22 pages and Siteimprove Alfa on 11 pages. Automated tools find roughly a third of real barriers — this report should be supplemented with manual AT testing and user research before making conformance claims. \"supports\" means no automated failure was detected this week, not that the criterion is fully met."
evaluation_methods_used: "Automated: axe-core  and Siteimprove Alfa, running in headless Chromium (Playwright). Rules are mapped to WCAG 2.2 success criteria. Manual AT testing has not been conducted — add manual findings directly to this YAML file."
