# Designesy — /contracts/a11y Canonical page: https://www.designesy.org/contracts/a11y --- ## Accessibility Accessibility is structural — it shapes the first version, not the last audit. This contract makes that principle machine-checkable. Version 0.1.0 · provisional · [machine export](https://www.designesy.org/contracts/a11y.json) ## Source authority axe-core 4.13.0 (Deque Systems) W3C WCAG 2.2 (W3C Recommendation, 2023-10-05) W3C Accessibility Conformance Testing — act-rules.github.io ## Conformance WCAG 2.2 Level AA (includes all A and AA from WCAG 2.0, 2.1, 2.2) `axe ruleset --wcag22 designesy-a11y-ruleset.json` axe rule → ACT rule ID → WCAG success criterion → WCAG principle → remediation hint ## Verification — 11 checks 11 checks. PASS=1, WARN=0.5, FAIL=0, N/A=excluded. Score = (points/applicable) × 100. A≥90, B≥80, C≥70, D≥60, F<60. ## Open questions - Server-side execution: CDP (existing infrastructure) vs Playwright (axe native driver)? - AAA targeting: which WCAG 2.2 AAA criteria should Designesy target selectively? - BridgePCA: adopt as contrast algorithm, or keep WCAG 2.2 with documented deviation? - Accessibility floor: raise from 60% to 70%? - Second-source triangulation: run IBM Equal Access Checker alongside axe?
