+> **Status**: 📝 Planned  
+> **Priority**: High   
+> **Complexity**: High   
+> **Estimate**: 12-16 hours   
+> **Assignee**: -   
+> **Created**: June 14, 2025   
+> **Target Completion**: -

+
+## 📌 Overview
+
+### Purpose
+Implement a comprehensive admin module that allows the application owner (Lasse) to manage users, generate story content, and access progress reports. This is **mission-critical** for the application as it enforces the requirement that **all visitors must sign up before accessing any learning content**.
+
+### User Stories
+- **As an admin**, I want to generate stories for levels so that users have content to learn from
+- **As an admin**, I want to view user lists and their progress so that I can monitor application usage
+- **As an admin**, I want to view progress reports so that I can understand how users are engaging with the platform
+- **As a visitor**, I must sign up and login before I can access any learning content (stories, lessons, quizzes)
+
+### Acceptance Criteria
+- [ ] All learning content endpoints require authentication (no public access)
+- [ ] User registration is mandatory before accessing any content
+- [ ] Admin role exists and is assigned to specific users only
+- [ ] Admin can access story generation UI/API
+- [ ] Admin can view list of all users
+- [ ] Admin can view individual user progress (lessons completed, stories unlocked)
+- [ ] Admin can generate reports on user activity
+- [ ] Admin endpoints are protected and only accessible to admin users
+

+
+### Non-Functional Requirements
+- Security: Admin endpoints must be protected with role-based authorization
+- Security: Admin role can only be assigned through direct database manipulation (not via API)
+- Performance: User list loading < 500ms for up to 10,000 users
+- Performance: Progress reports generation < 2 seconds

+
+---
+
+## 🏗️ Technical Design
+
+### Components Involved
+
+#### Backend (GermanApp)
+- **Controllers**: AdminController (new), UserController (new), ReportController (new)
+- **Services**: AdminService (new), UserReportService (new)
+- **Entities**: User (existing), StorySegment (existing), StoryProgress (existing), UserProgress (existing)
+- **Repositories**: IUserRepository (existing), IStoryProgressRepository (existing), IUserProgressRepository (existing)
+- **DTOs**: UserDto, UserListDto, UserProgressDto, ProgressReportDto, StoryGenerationRequestDto (existing)
+- **Middleware**: Role-based authorization (existing JWT infrastructure)
+
+#### Frontend (german-app-frontend)
+- **Pages**: AdminDashboard (new), AdminUsers (new), AdminReports (new), AdminStoryGenerator (new)
+- **Components**: UserList (new), UserCard (new), ProgressChart (new), StoryGenerationForm (new)
+- **Services**: adminApi (new), authService (existing)
+- **Types**: User, UserProgress, ProgressReport (new)
+- **Routing**: Protected admin routes with role check
+
+#### Infrastructure
+- **Database**: No new tables needed (uses existing Users, StoryProgress, UserProgress, StorySegments)
+- **Configuration**: Admin role configuration in JWT claims
+
+### Data Flow
+
+#### User Authentication Flow (Mandatory)
+```
+1. Visitor arrives at / (home page)
+2. Frontend checks localStorage for JWT token
+3. If no token → redirect to /login
+4. User enters credentials → POST /api/auth/login
+5. Backend validates → returns JWT token
+6. Frontend stores token → redirects to /learn or /story/1
+7. All subsequent requests include Authorization: Bearer <token>
+8. Backend middleware validates token → allows access to protected endpoints
+```
+
+#### Story Generation Flow (Admin Only)
+```
+1. Admin navigates to /admin/stories
+2. Frontend verifies user has admin role (from JWT claims)
+3. Admin selects level (1-5) and enters theme
+4. Frontend POST /api/admin/stories/generate with {levelId, theme, segmentCount}
+5. Backend verifies admin role
+6. Backend extracts vocabulary from level's lessons
+7. Backend calls Mistral AI with CEFR-specific prompt
+8. Backend splits story into segments
+9. Backend saves segments to database
+10. Backend returns success with generated segments
+11. Frontend shows success message
+```
+
+#### User Management Flow (Admin Only)
+```
+1. Admin navigates to /admin/users
+2. Frontend verifies admin role
+3. Frontend GET /api/admin/users
+4. Backend verifies admin role
+5. Backend fetches all users from database
+6. Backend returns user list with basic info
+7. Frontend displays user table with filters
+8. Admin clicks on user → GET /api/admin/users/{id}/progress
+9. Backend returns detailed progress for that user
+10. Frontend displays user progress dashboard
+```
+
+#### Report Generation Flow (Admin Only)
+```
+1. Admin navigates to /admin/reports
+2. Frontend verifies admin role
+3. Admin selects report type (user activity, progress, etc.)
+4. Frontend GET /api/admin/reports/{type}?startDate=...&endDate=...
+5. Backend verifies admin role
+6. Backend aggregates data based on report type
+7. Backend returns report data
+8. Frontend renders report with charts/tables
+```
+
+### API Endpoints
+
+#### Admin Endpoints (Require Admin Role)
+| Endpoint | Method | Description | Auth Required | Admin Only |
+|----------|--------|-------------|----------------|------------|
+| `/api/admin/stories/generate` | POST | Generate story for a level | Yes | Yes |

+| `/api/quizzes/*` | GET | All quiz endpoints | Yes | Added [Authorize] |
+| `/api/levels/*` | GET | All level endpoints | Yes | Added [Authorize] |
+
+### Database Schema
+No new tables required. Uses existing:
+- `Users` - User accounts
+- `StorySegments` - Story content
+- `StoryProgress` - Which story segments user has unlocked/completed
+- `UserProgress` - Lesson completion tracking

+## 📝 Notes & Decisions
+
+### Design Decisions
+
+1. **Single Admin User**: Initially, there will be only one admin user (Lasse). Admin role will not be assignable via API to prevent privilege escalation attacks. Admin role will be set directly in the database.
+
+2. **Mandatory Authentication**: ALL learning content requires authentication. No exceptions. This is a core business requirement. Users cannot access stories, lessons, or quizzes without first registering and logging in.
+
+3. **Role-Based Authorization**: Using ASP.NET Core's built-in `[Authorize(Roles = "Admin")]` attribute for admin-only endpoints. Regular authenticated users can access learning content, but only admin users can access admin endpoints.
+
+4. **Progress Tracking**: User progress (lesson completion, story unlock/completion) is tracked per user and is essential for the story unlocking feature to work correctly.
+
+### Gotchas & Considerations
+
+- **CORS with Credentials**: When using JWT tokens with credentials, CORS configuration must explicitly list allowed origins (cannot use wildcard `AllowAnyOrigin()` with `AllowCredentials()`).
+- **Token Storage**: Frontend stores JWT tokens in localStorage. Consider HttpOnly cookies for enhanced security (future enhancement).
+- **Admin Bootstrapping**: First admin user must be created via direct database manipulation or a special bootstrap endpoint (which should be removed after first use).
+- **Role Migration**: Existing User table may need a `Role` column added via migration.
+
+### Future Enhancements
+
+- [ ] Admin user management (add/remove admins via UI)
+- [ ] Admin action audit logging
+- [ ] User export/import functionality
+- [ ] Bulk story generation
+- [ ] Scheduled report generation (email)
+- [ ] User activity notifications
