      What this check looks for
    Description, as the server wrote it
    Run an automated accessibility check (axe-core + Lighthouse) on ONE public http(s) web page and return a score, badge tier, and the most important violations with CSS selectors so you can suggest fixes. Takes up to ~1–2 minutes. Automated checks cannot prove WCAG conformance: 'no automated errors found' still needs manual review. Only public pages are accepted (private/localhost addresses are rejected). (공개 웹 페이지 1개 자동 접근성 검사. 자동 검사는 준수를 증명하지 못하며 수동 확인이 남음.)

    Why it is in this group

    • The name "a11y_get_result" says "get": a word for reading.
    Description, as the server wrote it
    Fetch the summary of a previously saved web accessibility check by its result ID (WIA-A11Y-XXXXXXXX), including top violations. Only results of web page checks are returned. (저장된 접근성 검사 결과 요약 조회.)

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
