---

## Phase 1: Foundation (Days 1-3)

### ✅ Day 1 - Completed

#### 1. Accessibility Tools Setup

**Installed Dependencies:**
```json
{
  "devDependencies": {

- `focusElement()` - Smart focus with scroll behavior

**Global CSS** (`app/globals.css`) - 119 lines added:
- Focus indicators: `:focus-visible` with coral outline (#FF8B7D)
- Skip navigation link with keyboard-only visibility
- Screen reader only class (`.sr-only`)
- Reduced motion support (`@media (prefers-reduced-motion: reduce)`)
- High contrast mode support
- Touch target helper class (44x44px minimum)

#### 2. Skip Navigation

- Meets WCAG 2.4.1 (Bypass Blocks) Level A requirement

**Root Layout Integration** (`app/layout.tsx`):
- Wrapped app with `AxeProvider` for dev-time testing
- Added `SkipNavigation` component at top of body
- Wrapped children in `<main id="main-content" tabIndex={-1}>`
- Provides skip target and programmatic focus capability

#### 3. ARIA Labels & Dialog Accessibility

**Dialogs Updated** (6 components):
1. **ChildDialog** (`components/children/ChildDialog.tsx`):
   - Added `aria-labelledby="child-dialog-title"`
   - Added `aria-describedby="child-dialog-description"`
   - Error alerts with `role="alert"`

2. **InviteMemberDialog** (`components/family/InviteMemberDialog.tsx`):

   - Verification code input with `aria-label="Six digit verification code"`
   - Loading indicator with `role="status"` and `aria-label`
   - Security icon with `aria-hidden="true"`
   - Error alerts with `role="alert"`

**Voice Input Accessibility** (`components/voice/VoiceFloatingButton.tsx`):
- Voice dialog with `aria-labelledby` and `aria-describedby`
- Microphone button with `aria-label` and `aria-pressed`
- Status text with `role="status"` and `aria-live="polite"`
- Classification result with `role="status"`
- Error messages with `role="alert"`
- Processing indicators with `aria-hidden="true"` on CircularProgress
- Unknown command dialog with ARIA labels
- Activity type select with `labelId` and `aria-label`

---

## ESLint Results

**Accessibility Warnings Found**: 7 instances of `jsx-a11y/no-autofocus`

**Analysis**:
- All autofocus instances are intentional and improve UX
- Used in dialogs where immediate keyboard input is expected:
  - Login/register forms
  - MFA verification code input
  - Child creation dialog
  - Family invitation dialog
  - Password reset forms
- Configured as "warn" rather than "error" to allow intentional use
- Each instance provides clear context and expected behavior

**Other Linter Issues** (non-accessibility):
- 38 unescaped quote errors (cosmetic, not accessibility)
- 15 React Hook dependency warnings (functionality, not accessibility)

---

### ✅ Day 2 - Keyboard Navigation Audit (In Progress)

**Audit Findings**:

✅ **Navigation Components** - Good keyboard support:
- `TabBar.tsx` - MUI BottomNavigation has built-in keyboard support
- `MobileNav.tsx` - MUI Drawer and List components are keyboard accessible
- All navigation items are properly focusable with Tab key

✅ **Dialogs & Modals** - Excellent keyboard support:
- MUI Dialog components have built-in focus trap
- Escape key to close
- Tab key cycles through dialog elements
- All 6 updated dialogs (Child, InviteMember, DeleteConfirm, RemoveMember, JoinFamily, MFAVerification)

✅ **Voice Input** - Good keyboard support:
- VoiceFloatingButton uses MUI Fab (keyboard accessible)
- Dialog keyboard navigation works properly

❌ **Critical Issue Fixed** - Quick Action Cards:
- **Problem**: Used `<Paper onClick={}>` which is not keyboard accessible
- **Solution**: Changed to `<Paper component="button">` with:
  - `onKeyDown` handler for Enter and Space keys
  - `aria-label` for screen readers
  - `:focus-visible` styles with white outline
  - Proper focus indicator matching hover state
- **File**: `app/page.tsx` (lines 136-173)

✅ **List Items** - Good keyboard support:
- Activities list uses MUI ListItem components
- Properly keyboard navigable

**Keyboard Navigation Checklist**:
- [x] Audit tab order across all pages
- [x] Verify keyboard access to all interactive elements
- [x] Test modal/dialog keyboard navigation (MUI built-in)
- [x] Fix non-keyboard accessible elements (Quick Actions fixed)
- [ ] Document keyboard shortcuts for users

### ✅ Day 2-3 - Semantic HTML & Landmarks

**Landmark Regions Added**:

- ✅ `<nav>` - Added to both navigation components:
  - MobileNav Toolbar (component="nav", aria-label="Primary navigation")
  - MobileNav Drawer (role="navigation", aria-label="Main menu")
  - TabBar (component="nav", aria-label="Primary navigation")
- ✅ `<main>` - Already exists in root layout (app/layout.tsx)

**Heading Hierarchy Fixed**:
- ✅ All page titles changed from h4 to proper h1:
  - app/page.tsx - "Welcome Back" (already fixed)
  - app/(auth)/login/page.tsx - "Welcome Back" (already fixed)
  - app/activities/page.tsx - "Recent Activities"
  - app/children/page.tsx - "Children"
  - app/family/page.tsx - "Family"
  - app/settings/page.tsx - "Settings"
- ✅ All subsection headings changed from h6 to proper h2:
  - app/children/page.tsx - "No children added yet"
  - app/family/page.tsx - "Family Share Code", "Family Members"
  - app/settings/page.tsx - "Profile Information", "Notifications", "Appearance", "Account Actions"

**Files Modified**:
- `components/layouts/MobileNav/MobileNav.tsx` - Added header, nav landmarks
- `components/layouts/TabBar/TabBar.tsx` - Added nav landmark
- `app/activities/page.tsx` - h1 heading
- `app/children/page.tsx` - h1 + h2 headings

- [ ] Add ARIA labels to data visualizations (charts - not yet implemented)

### ✅ Day 3 - Focus Management

**Focus Management Hook Created** (`hooks/useFocusManagement.ts`):
- ✅ `useFocusOnRouteChange()` - Automatically focuses h1 heading on page navigation
- ✅ Screen reader announcements for route changes (aria-live region)
- ✅ `useFocusTrap()` - Returns focus to previous element when modals close
- ✅ `useFocusOnNotification()` - Focuses important notifications/toasts
- ✅ Page title mapping for friendly screen reader announcements

**Provider Integration** (`components/providers/FocusManagementProvider.tsx`):
- ✅ Created client-side provider wrapper
- ✅ Integrated into root layout (app/layout.tsx)
- ✅ Automatic focus management across all pages

**Features Implemented**:
1. **Route Change Focus** - Moves focus to h1 on navigation (WCAG 2.4.3)
2. **Screen Reader Announcements** - "Navigated to [Page Name]" via aria-live
3. **Focus Restoration** - useFocusTrap hook for modals (MUI Dialogs already handle this)
4. **Notification Focus** - useFocusOnNotification hook available for important alerts

**Files Created**:
- `hooks/useFocusManagement.ts` (173 lines)
- `components/providers/FocusManagementProvider.tsx` (17 lines)

**Files Modified**:
- `app/layout.tsx` - Integrated FocusManagementProvider

**Testing Checklist**:

### Manual Testing:
- [ ] Keyboard-only navigation (no mouse)
- [ ] Screen reader testing (NVDA, JAWS, VoiceOver, TalkBack)
- [ ] High contrast mode verification
- [ ] Text scaling (200%) verification
- [ ] Reduced motion verification

### Tools to Use:
- Chrome DevTools Lighthouse
- axe DevTools browser extension

## Known Issues

1. **Autofocus warnings** - Intentional for UX, configured as warnings
2. **Color contrast** - Needs full audit with contrast checker utility
3. **Heading hierarchy** - Needs audit across all pages
4. **Landmarks** - Main landmark added to root, need page-specific landmarks
5. **Alt text** - Need to audit all images for descriptive alt text
