+# Additional Pages Implementation - 2025-11-16
+
+## Summary
+
+Built out **Login** and **Settings** pages (Tasks T105-T109, T120), added React Router for navigation, and implemented protected routes.
+
+## What Was Built
+
+### 1. Auth Service (T105-T107)
+**File**: `frontend/src/services/auth.ts`
+
+Functions:
+- `login()` - Redirect to `/auth/login` for HF OAuth
+- `getCurrentUser()` - GET `/api/me` to fetch user profile
+- `getToken()` - POST `/api/tokens` to generate new API token
+- `logout()` - Clear token and redirect
+- `isAuthenticated()` - Check if user has token
+- `getStoredToken()` - Get current token from localStorage
+
+### 2. Login Page (T108)
+**File**: `frontend/src/pages/Login.tsx`
+
+Features:
+- ✅ Centered card layout with app branding
+- ✅ "Sign in with Hugging Face" button (primary)
+- ✅ "Continue as Local Dev" button (for development)
+- ✅ Clean, professional dark mode design
+- ✅ Responsive layout
+
+Local dev mode sets a dummy token in localStorage for testing without backend OAuth.
+
+### 3. Settings Page (T109, T120)
+**File**: `frontend/src/pages/Settings.tsx`
+
+Features:
+- ✅ **Profile Card**
+  - User avatar (from HF profile or fallback initials)
+  - Username and user ID display
+  - Vault path
+  - Sign Out button
+
+- ✅ **API Token Card**
+  - Bearer token display (password field)
+  - Copy to clipboard button (with success feedback)
+  - "Generate New Token" button
+  - MCP configuration example with actual token
+
+- ✅ **Index Health Card**
+  - Note count display
+  - Last updated timestamp
+  - Last full rebuild timestamp
+  - "Rebuild Index" button with loading state
+  - Success message after rebuild
+
+### 4. Routing & Protected Routes
+**File**: `frontend/src/App.tsx`
+
+Added React Router v6:
+- `/login` - Public login page
+- `/` - Protected main app (requires auth)
+- `/settings` - Protected settings page (requires auth)
+- Auto-redirect to `/login` if not authenticated
+
+### 5. Navigation Integration
+
+**Updated MainApp.tsx**:
+- Added Settings button (gear icon) in header
+- Clicking navigates to `/settings`
+- Back button in Settings returns to `/`
+
+## Pages Flow

+```
+
+## Dark Mode
+
+All pages use dark mode by default (set in `main.tsx`).
+
+## Dependencies Added
+
+```bash
+npm install react-router-dom
+```
+
+## Backend Integration Status
+
+Pages are **fully built** but show loading states or errors because backend APIs don't exist yet:
+
+- Login page: Works (local dev mode bypasses OAuth)
+- Settings page:
+  - Profile: Shows "Loading user data..." (needs `GET /api/me`)
+  - API Token: Shows token from localStorage (needs `POST /api/tokens`)
+  - Index Health: Shows "Loading index health..." (needs `GET /api/index/health`)
+  - Rebuild Index: Button present (needs `POST /api/index/rebuild`)
+
+## What Works Right Now
+
+✅ Login page displays
+✅ Local dev login works (sets token, redirects to main app)
+✅ Protected routes redirect to login if no token
+✅ Settings page displays with proper layout
+✅ Token copy to clipboard works
+✅ Navigation between pages works
+✅ Back button works
+✅ Sign out clears token and returns to login
+
+## What Needs Backend
+
+⏳ HF OAuth flow (backend routes `/auth/login`, `/auth/callback`)
+⏳ User profile data (`GET /api/me`)
+⏳ Token generation (`POST /api/tokens`)
+⏳ Index health data (`GET /api/index/health`)
+⏳ Index rebuild (`POST /api/index/rebuild`)
+
+## Files Created
+
+```
+frontend/src/
+├── services/
+│   └── auth.ts              (new - 76 lines)
+└── pages/
+    ├── Login.tsx            (new - 59 lines)
+    └── Settings.tsx         (new - 255 lines)
+
+Modified:
+├── App.tsx                  (updated - added routing)
+└── pages/MainApp.tsx        (updated - added settings button)
+```
+
+## Task Status
+
+✅ T105 - Auth service login function
+✅ T106 - Auth service getCurrentUser function
+✅ T107 - Auth service getToken function
+✅ T108 - Login page with HF OAuth button
+✅ T109 - Settings page with profile and token
+✅ T120 - Rebuild index button in settings
+
+## Testing
+
+### Login Page
+1. Navigate to http://localhost:5173/
+2. Should redirect to `/login` (no token)
+3. Click "Continue as Local Dev"
+4. Should redirect to main app
+
+### Settings Page
+1. From main app, click Settings icon (⚙️)
+2. Should show Settings page with 3 cards
+3. Profile shows "Loading..." (expected - no backend)
+4. Token shows "local-dev-token"
+5. Click Copy button → token copied to clipboard
+6. Index Health shows "Loading..." (expected - no backend)
+
+### Navigation
+1. Click Back button → returns to main app
+2. Click Settings icon → returns to settings
+3. Sign out from settings → returns to login page
+
+All navigation works perfectly!
+
+## Summary
+
+**3 new pages built and integrated**:
+- ✅ Login page with HF OAuth + local dev mode
+- ✅ Settings page with profile, tokens, and index health
+- ✅ Routing with protected routes
+
+**Ready for backend integration** - Once you implement the backend auth routes (T095-T104), the pages will be fully functional!
