Test Registry
The 2415 executable tests behind Insights analysis, ranking, and New Internet scoring. Each test has a stable ID, suite, weight, severity, output schema, trace span name, and remediation guidance. No mock scoring is published as real data, and accessibility checks now include the W3C WAI standards/guidelines matrix (including ACT, WCAG 2.2/2.1/2.0, EPUB Accessibility 1.1, ARIA, ATAG, UAAG, and related guidance).
