## Auth Endpoints (REST, not tRPC)

Auth endpoints use REST-style HTTP routes at `/api/auth/{action}`:

| Android AuthRepository Method | Endpoint | Status |
|-------------------------------|----------|--------|
| `login()` | `POST /api/auth/login` | ✅ Response parsing fixed |
| `signup()` | `POST /api/auth/signup` | ✅ Response parsing fixed |
| `signInWithGoogle()` | `POST /api/auth/google` | ✅ Response parsing fixed |
| `refreshAccessToken()` | `POST /api/auth/refresh` | ✅ Response parsing fixed |
| `forgotPassword()` | `POST /api/auth/forgot-password` | ✅ Verified |
| `resetPassword()` | `POST /api/auth/reset-password` | ✅ Email param removed (backend expects code+password only) |
| `logout()` | `POST /api/auth/logout` | ✅ Verified |

**Response format** — backend returns flat JSON (not tRPC-nested):
```json
{
  "id": "user_123",
  "name": "User Name",
  "email": "user@example.com",
  "image": "https://...",
  "accessToken": "jwt...",
  "refreshToken": "jwt...",
  "isNewUser": false
}
```

## Changes Made

### Issues Found and Fixed

1. **Mismatched endpoint paths** (18 endpoints renamed)
   - Procedure names must match `appRouter` hierarchy exactly
   - Fixed `user.updateProfile` → `user.update`, `voice.analyze` → `voiceprint.analyzeAudio`, etc.

2. **Auth response parsing** (`AuthRepository.kt`)
   - Backend returns flat JSON (not tRPC nested)
   - Fixed to use `optString()`/`optBoolean()` with proper defaults
   - Removed unnecessary `result.data.user` nesting lookup

3. **Missing endpoints** (20 endpoints added)
   - Added billing, darkwatch admin, voiceprint management, notification preferences endpoints

4. **Hardcoded base URLs** (`TokenRefreshManager`, `AuthInterceptor`)
   - Both used hardcoded `https://kordant.ai/api` instead of `BuildConfig.API_BASE_URL`
   - Fixed to use `BuildConfig.API_BASE_URL + "/api"` for all token refresh operations

5. **PII exposure in logs** (`NetworkModule`)
   - Changed from `HttpLoggingInterceptor.Level.BODY` to `HEADERS` in production
   - Added sanitization regex to mask tokens, passwords, emails, and phone numbers
   - Debug builds log at HEADERS level with sanitized messages

6. **Paginated endpoints** (9 endpoints)
   - Backend does not yet support cursor-based pagination
   - Paging sources now use regular list endpoints with manual `PaginatedData` wrapping
   - Documents that when backend adds pagination support, cursor/limit params pass through

7. **Request format for backend procedures**
   - `spamshield.createRule` — backend expects `ruleType`, `pattern`, `action`, `priority`
   - `hometitle.addProperty` — backend expects `address`, `parcelId`, `ownerName`
   - `removebrokers.createRemovalRequest` — backend expects `brokerId`, `personalInfo` object
   - `darkwatch.removeWatchlistItem` — backend expects `itemId` (not `id`)
   - `notification.registerDevice` — backend expects `token`, `platform`, `deviceType`
   - All repository request bodies updated to match backend input schemas
