+
+---
+
+## Phase 1: Foundation (Days 1-3)
+
+### ✅ Day 1 - Completed
+
+#### 1. Accessibility Tools Setup
+
+**Installed Dependencies:**
+```json
+{
+  "devDependencies": {
+    "eslint-plugin-jsx-a11y": "^6.10.2",
+    "jest-axe": "^10.0.0",
+    "@axe-core/react": "^4.10.2",
+    "eslint-config-next": "^15.5.4"

+  "dependencies": {
+    "react-focus-lock": "^2.13.6",
+    "focus-trap-react": "^11.0.4"
+  }
+}
+```
+
+**ESLint Configuration** (`.eslintrc.json`):
+- Extended `plugin:jsx-a11y/recommended`

+  - `jsx-a11y/tabindex-no-positive`: error
+
+**Development Testing** (`components/providers/AxeProvider.tsx`):
+- Auto-loads `@axe-core/react` in development mode
+- Logs violations to console for immediate feedback
+- Configured rules: color-contrast, label, button-name, link-name
+- Only runs in development to avoid production performance impact
+
+**Accessibility Utilities** (`lib/accessibility.ts`):
+- `announceToScreenReader()` - Screen reader announcements with aria-live
+- `prefersReducedMotion()` - Detects user motion preferences
+- `trapFocus()` - Focus trap for modals/dialogs
+- `getFocusableElements()` - Query focusable elements
+- `getContrastRatio()` - WCAG contrast ratio calculator
+- `meetsContrastRequirements()` - AA/AAA compliance checker
+- `generateA11yId()` - Unique IDs for ARIA attributes
+- `isElementFocusable()` - Visibility and focusability checker
+- `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
+
+**Component Created** (`components/common/SkipNavigation.tsx`):
+- "Skip to main content" link for keyboard users
+- Visually hidden until focused
+- Smooth scroll to `#main-content`
+- 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`):
+   - Added `aria-labelledby="invite-dialog-title"`
+   - Added `aria-describedby="invite-dialog-description"`
+   - Error alerts with `role="alert"`
+
+3. **DeleteConfirmDialog** (`components/children/DeleteConfirmDialog.tsx`):
+   - Added `role="alertdialog"` for destructive action
+   - Added `aria-labelledby` and `aria-describedby`
+   - Warning icon with `aria-hidden="true"`
+
+4. **RemoveMemberDialog** (`components/family/RemoveMemberDialog.tsx`):
+   - Added `role="alertdialog"`
+   - Added ARIA labels
+   - Warning icon with `aria-hidden="true"`
+
+5. **JoinFamilyDialog** (`components/family/JoinFamilyDialog.tsx`):
+   - Added `aria-labelledby` and `aria-describedby`
+   - Error alerts with `role="alert"`
+
+6. **MFAVerificationDialog** (`components/auth/MFAVerificationDialog.tsx`):
+   - Added `aria-labelledby` and `aria-describedby`
+   - 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)

+- Fixed password visibility button (added `aria-label`)
+- Fixed missing h1 headings on login and home pages
+- Fixed color contrast violations:
+  - Updated theme `text.secondary` color: #718096 → #4A5568 (7:1+ contrast)
+  - Fixed "Maternal" header color in MobileNav
+  - Fixed "Resend Email" button contrast in EmailVerificationBanner
+  - Updated all Quick Action card colors to WCAG AA (4.5:1 minimum)

+
+---
+
+### ✅ 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**:
+- ✅ `<header>` - Added to MobileNav AppBar (component="header")
+- ✅ `<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
+- `app/family/page.tsx` - h1 + h2 headings
+- `app/settings/page.tsx` - h1 + h2 headings

+- [ ] Add ARIA live regions for toast notifications (Snackbar already has role="alert")
+- [ ] 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)

+
+### 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
+- NVDA (Windows)
+- JAWS (Windows)
+- VoiceOver (macOS/iOS)
+- TalkBack (Android)
+
+---
+
+## 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
