+``` + +## WCAG 2.2 Core Compliance Checklist + +### 1. Perceivable (Information must be presentable) + +- [ ] **Text Alternatives**: All non-text content has a text alternative (Alt text or labels). +- [ ] **Contrast**: Text meets 4.5:1; UI components/graphics meet 3:1 contrast ratios. +- [ ] **Adaptable**: Content reflows and remains functional when resized up to 400%. + +### 2. Operable (Interface components must be usable) + +- [ ] **Keyboard Accessible**: Every interactive element is reachable via keyboard/switch control. +- [ ] **Navigable**: Focus order is logical, and focus indicators are high-contrast (SC 2.4.11). +- [ ] **Pointer Gestures**: Single-pointer alternatives exist for all dragging or multipoint gestures. +- [ ] **Target Size**: Interactive elements are at least 24x24 CSS pixels (SC 2.5.8). + +### 3. Understandable (Information must be clear) + +- [ ] **Predictable**: Navigation and identification of elements are consistent across the app. +- [ ] **Input Assistance**: Forms provide clear error identification and suggestions for fix. +- [ ] **Redundant Entry**: Avoid asking for the same info twice in a single process (SC 3.3.7). + +### 4. Robust (Content must be compatible) + +- [ ] **Compatibility**: Maximize compatibility with assistive tech using valid Name, Role, and Value. +- [ ] **Status Messages**: Screen readers are notified of dynamic changes via ARIA live regions. + +--- + +## Anti-Patterns + +| Issue | Why it fails | +| :------------------------- | :------------------------------------------------------------------------------------------------- | +| **"Click Here" Links** | Non-descriptive; screen reader users navigating by links won't know the destination. | +| **Fixed-Sized Containers** | Prevents content reflow and breaks the layout at higher zoom levels. | +| **Keyboard Traps** | Prevents users from navigating the rest of the page once they enter a component. | +| **Auto-Playing Media** | Distracting for users with cognitive disabilities; interferes with screen reader audio. | +| **Empty Buttons** | Icon-only buttons without an `aria-label` or `accessibilityLabel` are invisible to screen readers. | + +## Accessibility Decision Record Template + +For major UI decisions, use this format: + +```markdown +# ADR-ACC-[000]: [Title of the Accessibility Decision] + +## Status + +Proposed | **Accepted** | Deprecated | Superseded by [ADR-XXX] + +## Context + +_Describe the UI component or workflow being addressed._ + +- **Platform**: [Web | iOS | Android | Cross-platform] +- **WCAG 2.2 Success Criterion**: [e.g., 2.5.8 Target Size (Minimum)] +- **Problem**: What is the current accessibility barrier?
