chore: update gitignore and vscode settings for venv, clean up instructions

- Reset _queue_progress_initialized after each queue run so the next
  run re-creates the 'download_queue' progress entry
- Handle 'already exists' ProgressServiceError in _init_queue_progress
  as a no-op success to cover concurrent-start edge cases
- Guard stop_downloads() progress update to avoid crashing when the
  entry was never created

 ## 1. General Philosophy
 
-*   **Clarity is King:** Code should be easy to understand at a glance.
-*   **Consistency Matters:** Adhere to these standards across all projects.
-*   **Automation Encouraged:**  Utilize tools like StyleCop, Roslyn Analyzers, and .editorconfig to enforce these standards automatically.
-*   **Evolve and Adapt:** These standards should be reviewed and updated as the C# language and best practices evolve.
-*   **Practicality Reigns:** While striving for perfection, prioritize pragmatic solutions that balance maintainability and development speed.

 ## 2. Security Considerations
 
-*   **Input Validation:** Always validate user input to prevent injection attacks (e.g., SQL injection, XSS).
-*   **Secure Configuration:** Store sensitive information (e.g., passwords, API keys) in secure configuration files, and encrypt them if possible.  Avoid hardcoding sensitive data.
-*   **Authentication and Authorization:** Implement proper authentication and authorization mechanisms to protect resources. Favor using built-in identity frameworks.
-*   **Data Encryption:** Encrypt sensitive data at rest and in transit.  Use strong encryption algorithms.
-*   **Regular Security Audits:**  Perform regular security audits and penetration testing to identify and address vulnerabilities.
-*   **Dependency Vulnerabilities:** Keep dependencies up-to-date to patch known security vulnerabilities. Use tools to automatically check for vulnerabilities.

 ## 3. Performance Optimization
 
-*   **Minimize Object Allocation:** Reduce unnecessary object allocations, especially in performance-critical code. Use techniques like object pooling and struct types for small value types.
-*   **Use Efficient Data Structures:** Choose the appropriate data structures for the task (e.g., "Dictionary" for fast lookups, "List" for ordered collections).
-*   **Avoid Boxing/Unboxing:** Avoid boxing and unboxing operations, as they can be expensive. Use generics to prevent boxing.
-*   **String Concatenation:** Use "StringBuilder" for building strings in loops instead of repeated string concatenation.
-*   **Asynchronous I/O:** Use asynchronous I/O operations to avoid blocking threads.
-*   **Profiling:** Use profiling tools to identify performance bottlenecks.

-# AniWorld FastAPI Documentation
-
-## Overview
-
-AniWorld has been successfully migrated from Flask to FastAPI, providing improved performance, automatic API documentation, and modern async support.
-
-## Accessing API Documentation
-
-### Interactive API Documentation
-
-FastAPI automatically generates interactive API documentation that you can access at:
-
--   **Swagger UI**: `http://localhost:8000/docs`
--   **ReDoc**: `http://localhost:8000/redoc`
-
-These interfaces allow you to:
-
--   Browse all available endpoints
--   View request/response schemas
--   Test API endpoints directly from the browser
--   Download OpenAPI schema
-
-### OpenAPI Schema
-
-The complete OpenAPI 3.0 schema is available at:
-
--   **JSON Format**: `http://localhost:8000/openapi.json`
-
-## Authentication
-
-### Master Password Authentication
-
-AniWorld uses a simple master password authentication system with JWT tokens.
-
-#### Login Process
-
-1. **POST** `/auth/login`
-    - Send master password in request body
-    - Receive JWT token in response
-    - Token expires in 24 hours
-
-```json
-{
-    "password": "your_master_password"
-}
-```
-
-Response:
-
-```json
-{
-    "success": true,
-    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
-    "message": "Login successful"
-}
-```
-
-#### Using Authentication Token
-
-Include the token in the `Authorization` header for authenticated requests:
-
-```
-Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...
-```
-
-## API Endpoints
-
-### System Health
-
--   **GET** `/health` - Check system health and status
--   **GET** `/api/system/database/health` - Check database connectivity
--   **GET** `/api/system/config` - Get system configuration
-
-### Authentication
-
--   **POST** `/auth/login` - Authenticate and get JWT token
--   **GET** `/auth/verify` - Verify current token validity
--   **POST** `/auth/logout` - Logout and invalidate token
--   **GET** `/api/auth/status` - Get current authentication status
-
-### Anime Management
-
--   **GET** `/api/anime/search` - Search for anime series
--   **GET** `/api/anime/{anime_id}` - Get specific anime details
--   **GET** `/api/anime/{anime_id}/episodes` - Get episodes for an anime
-
-### Episode Management
-
--   **GET** `/api/episodes/{episode_id}` - Get specific episode details
-
-### Series Management
-
--   **POST** `/api/add_series` - Add a new series to tracking
--   **POST** `/api/download` - Start episode download
-
-### Web Interface
-
--   **GET** `/` - Main application interface
--   **GET** `/app` - Application dashboard
--   **GET** `/login` - Login page
--   **GET** `/setup` - Setup page
--   **GET** `/queue` - Download queue interface
-
-## Response Formats
-
-### Success Responses
-
-All successful API responses follow this structure:
-
-```json
-{
-  "success": true,
-  "data": {...},
-  "message": "Operation completed successfully"
-}
-```
-
-### Error Responses
-
-Error responses include detailed error information:
-
-```json
-{
-  "success": false,
-  "error": "Error description",
-  "code": "ERROR_CODE",
-  "details": {...}
-}
-```
-
-## Status Codes
-
--   **200 OK** - Successful operation
--   **201 Created** - Resource created successfully
--   **400 Bad Request** - Invalid request data
--   **401 Unauthorized** - Authentication required
--   **403 Forbidden** - Insufficient permissions
--   **404 Not Found** - Resource not found
--   **422 Unprocessable Entity** - Validation error
--   **500 Internal Server Error** - Server error
-
-## Rate Limiting
-
-Currently, no rate limiting is implemented, but it may be added in future versions.
-
-## WebSocket Support
-
-Real-time updates are available through WebSocket connections for:
-
--   Download progress updates
--   Scan progress updates
--   System status changes
-
-## Migration Notes
-
-### Changes from Flask
-
-1. **Automatic Documentation**: FastAPI provides built-in OpenAPI documentation
-2. **Type Safety**: Full request/response validation with Pydantic
-3. **Async Support**: Native async/await support for better performance
-4. **Modern Standards**: OpenAPI 3.0, JSON Schema validation
-5. **Better Error Handling**: Structured error responses with detailed information
-
-### Breaking Changes
-
--   Authentication tokens are now JWT-based instead of session-based
--   Request/response formats may have slight differences
--   Some endpoint URLs may have changed
--   WebSocket endpoints use FastAPI WebSocket pattern
-
-## Development
-
-### Running the Server
-
-```bash
-# Development mode with auto-reload
-uvicorn src.server.fastapi_app:app --host 127.0.0.1 --port 8000 --reload
-
-# Production mode
-uvicorn src.server.fastapi_app:app --host 0.0.0.0 --port 8000
-```
-
-### Environment Variables
-
--   `MASTER_PASSWORD_HASH` - Hashed master password
--   `JWT_SECRET_KEY` - Secret key for JWT token signing
--   `LOG_LEVEL` - Logging level (DEBUG, INFO, WARNING, ERROR)

-# AniWorld Project Overview
-
-## 📁 Folder Structure
-
-The project follows a modular, layered architecture inspired by MVC and Clean Architecture principles. The main directories are:
-
-```
-src/
-  controllers/    # API endpoints and route handlers
-  services/       # Business logic and orchestration
-  repositories/   # Data access layer (DB, external APIs)
-  schemas/        # Pydantic models for validation/serialization
-  utils/          # Utility functions and helpers
-  config/         # Configuration management (env, settings)
-tests/
-  unit/           # Unit tests for core logic
-  integration/    # Integration tests for end-to-end scenarios
-```
-
-## 🏗️ Architecture
-
-- **MVC & Clean Architecture:** Separation of concerns between controllers (views), services (business logic), and repositories (data access).
-- **Dependency Injection:** Used for service/repository wiring, especially with FastAPI's `Depends`.
-- **Event-Driven & Microservices Ready:** Modular design allows for future scaling into microservices or event-driven workflows.
-- **Centralized Error Handling:** Custom exceptions and error middleware for consistent API responses.
-
-## 🧰 Used Libraries & Frameworks
-
-- **Python** (PEP8, PEP257, type hints)
-- **FastAPI**: High-performance async web API framework
-- **Pydantic**: Data validation and serialization
-- **Poetry**: Dependency management and packaging
-- **dotenv / os.environ**: Environment variable management
-- **logging / structlog**: Structured logging
-- **pytest / unittest**: Testing frameworks
-- **aiohttp**: Async HTTP client (where needed)
-- **SQLAlchemy / asyncpg / databases**: Database ORM and async drivers (if present)
-- **Prometheus**: Metrics endpoint integration
-- **Other**: As required for integrations (webhooks, third-party APIs)
-
-## 🧩 Patterns & Conventions
-
-- **Repository Pattern:** All data access is abstracted via repositories.
-- **Service Layer:** Business logic is encapsulated in services, not controllers.
-- **Pydantic Models:** Used for all input/output validation.
-- **Async Endpoints:** All I/O-bound endpoints are async for scalability.
-- **Environment Configuration:** All secrets/configs are loaded from `.env` or environment variables.
-- **Logging:** All logs are structured and configurable.
-- **Testing:** High coverage with fixtures and mocks for external dependencies.
-
-## 🛡️ Security & Performance
-
-- **JWT Authentication:** Secure endpoints with token-based auth.
-- **Input Validation:** All user input is validated via Pydantic.
-- **No Hardcoded Secrets:** All sensitive data is externalized.
-- **Performance Optimization:** Async I/O, caching, and profiling tools.
-
-## 🎨 UI & CLI
-
-- **Theme Support:** Light/dark/auto modes.
-- **Accessibility:** Screen reader, color contrast, keyboard shortcuts.
-- **CLI Tool:** For bulk operations, scanning, and management.

+
+## Application Lifecycle
+
+### Initialization
+
+On first startup, the application performs a one-time sync of series from data files to the database:
+
+1. FastAPI lifespan starts
+2. Database is initialized
+3. `sync_series_from_data_files()` reads all data files from the anime directory (creates temporary SeriesApp)
+4. Series metadata is synced to the database
+5. DownloadService initializes (triggers main `SeriesApp` creation)
+6. `SeriesApp` loads series from database via service layer (not from files)
+
+On subsequent startups, the same flow applies but the sync finds no new series. `SeriesApp` always initializes with an empty series list (`skip_load=True`) and loads data from the database on demand, avoiding redundant file system scans.
+
+### Adding New Series
+
+When adding a new series:
+
+1. Series is added to the database via `AnimeService`
+2. Data file is created in the anime directory
+3. In-memory `SerieList` is updated via `load_series_from_list()`

-## 📝 Migration Notes
-
-### Important FastAPI Concepts to Remember:
-
--   FastAPI uses async/await by default (but sync functions work too)
--   Automatic request/response validation with Pydantic
--   Built-in OpenAPI documentation
--   Dependency injection system
--   Type hints are crucial for FastAPI functionality
-
-### Common Gotchas:
-
--   FastAPI doesn't have built-in session support (use external library if needed)
--   Template responses need explicit media_type for HTML
--   Static file mounting needs to be configured explicitly
--   Request object structure is different from Flask
-
-### Performance Considerations:
-
--   FastAPI is generally faster than Flask
--   Consider using async functions for I/O operations
--   Use background tasks for long-running operations
--   Implement proper caching strategies

+
+## Document Purpose
+
+This document describes the system architecture of the Aniworld anime download manager.
+
+---
+
+## 1. System Overview
+
+Aniworld is a web-based anime download manager built with Python, FastAPI, and SQLite. It provides a REST API and WebSocket interface for managing anime libraries, downloading episodes, and tracking progress.
+
+### High-Level Architecture

+### 2.1 CLI Layer (`src/cli/`)
+
+Legacy command-line interface for direct interaction with the core layer.

+```
+
+Source: [src/server/](../src/server/)
+
+### 2.2.1 Frontend Architecture (`src/server/web/static/`)
+
+The frontend uses a modular architecture with no build step required. CSS and JavaScript files are organized by responsibility.
+
+#### CSS Structure
+
+```
+src/server/web/static/css/
++-- styles.css              # Entry point with @import statements
++-- base/
+|   +-- variables.css       # CSS custom properties (colors, fonts, spacing)
+|   +-- reset.css           # CSS reset and normalize styles
+|   +-- typography.css      # Font styles, headings, text utilities
++-- components/
+|   +-- buttons.css         # All button styles
+|   +-- cards.css           # Card and panel components
+|   +-- forms.css           # Form inputs, labels, validation styles
+|   +-- modals.css          # Modal and overlay styles
+|   +-- navigation.css      # Header, nav, sidebar styles
+|   +-- progress.css        # Progress bars, loading indicators
+|   +-- notifications.css   # Toast, alerts, messages
+|   +-- tables.css          # Table and list styles
+|   +-- status.css          # Status badges and indicators
++-- pages/
+|   +-- login.css           # Login page specific styles
+|   +-- index.css           # Index/library page specific styles
+|   +-- queue.css           # Queue page specific styles
++-- utilities/
+    +-- animations.css      # Keyframes and animation classes
+    +-- responsive.css      # Media queries and breakpoints
+    +-- helpers.css         # Utility classes (hidden, flex, spacing)
+```
+
+#### JavaScript Structure
+
+JavaScript uses the IIFE pattern with a shared `AniWorld` namespace for browser compatibility without build tools.
+
+```
+src/server/web/static/js/
++-- shared/                 # Shared utilities used by all pages
+|   +-- constants.js        # API endpoints, localStorage keys, defaults
+|   +-- auth.js             # Token management (getToken, setToken, checkAuth)
+|   +-- api-client.js       # Fetch wrapper with auto-auth headers
+|   +-- theme.js            # Dark/light theme toggle
+|   +-- ui-utils.js         # Toast notifications, format helpers
+|   +-- websocket-client.js # Socket.IO wrapper
++-- index/                  # Index page modules
+|   +-- series-manager.js   # Series list rendering and filtering
+|   +-- selection-manager.js# Multi-select and bulk download
+|   +-- search.js           # Series search functionality
+|   +-- scan-manager.js     # Library rescan operations
+|   +-- scheduler-config.js # Scheduler configuration
+|   +-- logging-config.js   # Logging configuration
+|   +-- advanced-config.js  # Advanced settings
+|   +-- main-config.js      # Main configuration and backup
+|   +-- config-manager.js   # Config modal orchestrator
+|   +-- socket-handler.js   # WebSocket event handlers
+|   +-- app-init.js         # Application initialization
++-- queue/                  # Queue page modules
+    +-- queue-api.js        # Queue API interactions
+    +-- queue-renderer.js   # Queue list rendering
+    +-- progress-handler.js # Download progress updates
+    +-- queue-socket-handler.js # WebSocket events for queue
+    +-- queue-init.js       # Queue page initialization
+```
+
+#### Module Pattern
+
+All JavaScript modules follow the IIFE pattern with namespace:
+
+```javascript
+var AniWorld = window.AniWorld || {};
+
+AniWorld.ModuleName = (function () {
+    "use strict";
+
+    // Private variables and functions
+
+    // Public API
+    return {
+        init: init,
+        publicMethod: publicMethod,
+    };
+})();
+```

+
+### 2.3 Core Layer (`src/core/`)
+
+Domain logic for anime series management.
+
+```
+src/core/
++-- SeriesApp.py            # Main application facade
++-- SerieScanner.py         # Directory scanning, targeted single-series scan

+|   +-- nfo_repair_service.py # Detect & repair incomplete tvshow.nfo files
+|   |                       #   (parse_nfo_tags, find_missing_tags, NfoRepairService)
+|   +-- tmdb_client.py      # Async TMDB API client
++-- utils/                  # Utility helpers (no side-effects)
+|   +-- nfo_generator.py    # TVShowNFO → XML serialiser
+|   +-- nfo_mapper.py       # TMDB API dict → TVShowNFO (tmdb_to_nfo_model,
+|   |                       #   _extract_rating_by_country, _extract_fsk_rating)
+|   +-- image_downloader.py # TMDB image downloader
++-- providers/              # External provider adapters
+|   +-- base_provider.py    # Loader interface
+|   +-- provider_factory.py # Provider registry
++-- interfaces/             # Abstract interfaces
+|   +-- callbacks.py        # Progress callback system
++-- exceptions/             # Domain exceptions
+    +-- Exceptions.py       # Custom exceptions
+```
+
+**Key Components:**
+
+| Component      | Purpose                                                                    |
+| -------------- | -------------------------------------------------------------------------- |
+| `SeriesApp`    | Main application facade for anime operations                               |
+| `SerieScanner` | Scans directories for anime; `scan_single_series()` for targeted scans     |
+| `Serie`        | Domain entity with `sanitized_folder` property for filesystem-safe names   |
+| `SerieList`    | Collection management with automatic folder creation using sanitized names |
+
+**Initialization:**
+
+`SeriesApp` is initialized with `skip_load=True` passed to `SerieList`, preventing automatic loading of series from data files on every instantiation. Series data is loaded once during application setup via `sync_series_from_data_files()` in the FastAPI lifespan, which reads data files and syncs them to the database. Subsequent operations load series from the database through the service layer.

+### 2.4 Infrastructure Layer (`src/infrastructure/`)
+
+Cross-cutting concerns.
+
+```
+src/infrastructure/
++-- logging/                # Structured logging setup
++-- security/               # Security utilities
+```
+
+### 2.5 Configuration Layer (`src/config/`)
+
+Application settings management.
+
+| Component | File                                     | Purpose                         |
+| --------- | ---------------------------------------- | ------------------------------- |
+| Settings  | [settings.py](../src/config/settings.py) | Environment-based configuration |

+
+---
+
+## 12. Startup Sequence
+
+The FastAPI lifespan function (`src/server/fastapi_app.py`) runs the following steps on every server start.
+
+### 12.1 Startup Order
+
+```
+1. Logging configured
+
+2. Temp folder purged  ← cleans leftover partial download files
+   +-- Iterate ./Temp/ and delete every file and sub-directory
+   +-- Create ./Temp/ if it does not exist
+   +-- Errors are logged as warnings; startup continues regardless
+
+3. Database initialised (required – abort on failure)
+   +-- SQLite file created / migrated via init_db()
+
+4. Configuration loaded from data/config.json
+   +-- Synced to settings (ENV vars take precedence)
+
+5. Progress & WebSocket services wired up
+
+6. Series loaded from database into memory
+
+7. Download service initialised (queue restored from DB)
+
+8. Background loader service started
+
+9. Scheduler service started
+
+10. NFO repair scan (queue incomplete tvshow.nfo files for background reload)
+```
+
+### 12.2 Temp Folder Guarantee
+
+Every server start begins with a clean `./Temp/` directory. This ensures that partial `.part` files or stale temp videos from a crashed or force-killed previous session are never left behind before new downloads start.
+
+Source: [src/server/fastapi_app.py](../src/server/fastapi_app.py)
+
+---
+
+## 11. Graceful Shutdown
+
+The application implements a comprehensive graceful shutdown mechanism that ensures data integrity and proper cleanup when the server is stopped via Ctrl+C (SIGINT) or SIGTERM.
+
+### 11.1 Shutdown Sequence
+
+```
+1. SIGINT/SIGTERM received
+   +-- Uvicorn catches signal
+   +-- Stops accepting new requests
+
+2. FastAPI lifespan shutdown triggered
+   +-- 30 second total timeout
+
+3. WebSocket shutdown (5s timeout)
+   +-- Broadcast {"type": "server_shutdown"} to all clients
+   +-- Close each connection with code 1001 (Going Away)
+   +-- Clear connection tracking data
+
+4. Download service stop (10s timeout)
+   +-- Set shutdown flag
+   +-- Persist active download as "pending" in database
+   +-- Cancel active download task
+   +-- Shutdown ThreadPoolExecutor with wait
+
+5. Progress service cleanup
+   +-- Clear event subscribers
+   +-- Clear active progress tracking
+
+6. Database cleanup (10s timeout)
+   +-- SQLite: Run PRAGMA wal_checkpoint(TRUNCATE)
+   +-- Dispose async engine
+   +-- Dispose sync engine
+
+7. Process exits cleanly
+```
+
+Source: [src/server/fastapi_app.py](../src/server/fastapi_app.py#L142-L210)
+
+### 11.2 Key Components
+
+| Component           | File                                                                | Shutdown Method                |
+| ------------------- | ------------------------------------------------------------------- | ------------------------------ |
+| WebSocket Service   | [websocket_service.py](../src/server/services/websocket_service.py) | `shutdown(timeout=5.0)`        |
+| Download Service    | [download_service.py](../src/server/services/download_service.py)   | `stop(timeout=10.0)`           |
+| Database Connection | [connection.py](../src/server/database/connection.py)               | `close_db()`                   |
+| Uvicorn Config      | [run_server.py](../run_server.py)                                   | `timeout_graceful_shutdown=30` |
+| Stop Script         | [stop_server.sh](../stop_server.sh)                                 | SIGTERM with fallback          |
+
+### 11.3 Data Integrity Guarantees
+
+1. **Active downloads preserved**: In-progress downloads are saved as "pending" and can resume on restart.
+
+2. **Database WAL flushed**: SQLite WAL checkpoint ensures all writes are in the main database file.
+
+3. **WebSocket clients notified**: Clients receive shutdown message before connection closes.
+
+4. **Thread pool cleanup**: Background threads complete or are gracefully cancelled.
+
+### 11.4 Manual Stop
+
+```bash
+# Graceful stop via script (sends SIGTERM, waits up to 30s)
+./stop_server.sh
+
+# Or press Ctrl+C in terminal running the server
+```
+
+Source: [stop_server.sh](../stop_server.sh#L1-L80)
+
+---
+
+## 3. Component Interactions
+
+### 3.1 Request Flow (REST API)
+
+```
+1. Client sends HTTP request
+2. AuthMiddleware validates JWT token (if required)
+3. Rate limiter checks request frequency
+4. FastAPI router dispatches to endpoint handler
+5. Endpoint calls service layer
+6. Service layer uses core layer or database
+7. Response returned as JSON
+```
+
+Source: [src/server/middleware/auth.py](../src/server/middleware/auth.py#L1-L209)
+
+### 3.2 Download Flow
+
+```
+1. POST /api/queue/add
+   +-- DownloadService.add_to_queue()
+       +-- QueueRepository.save_item() -> SQLite
+
+2. POST /api/queue/start
+   +-- DownloadService.start_queue_processing()
+       +-- Process pending items sequentially
+       +-- ProgressService emits events
+       +-- WebSocketService broadcasts to clients
+
+3. During download:
+   +-- Provider writes to ./Temp/<filename>  (+ ./Temp/<filename>.part fragments)
+   +-- ProgressService.emit("progress_updated")
+   +-- WebSocketService.broadcast_to_room()
+   +-- Client receives WebSocket message
+
+4. After download attempt (success OR failure):
+   +-- _cleanup_temp_file() removes ./Temp/<filename> and all .part fragments
+   +-- On success: file was already moved to final destination before cleanup
+   +-- On failure / exception: no partial files remain in ./Temp/
+```
+
+#### Temp Directory Contract
+
+| Situation                        | Outcome                                                             |
+| -------------------------------- | ------------------------------------------------------------------- |
+| Server start                     | Entire `./Temp/` directory is purged before any service initialises |
+| Successful download              | Temp file moved to destination, then removed from `./Temp/`         |
+| Failed download (provider error) | Temp + `.part` fragments removed by `_cleanup_temp_file()`          |
+| Exception / cancellation         | Temp + `.part` fragments removed in `except` block                  |

+[src/core/providers/enhanced_provider.py](../src/core/providers/enhanced_provider.py)
+
+### 3.3 WebSocket Event Flow
+
+```
+1. Client connects to /ws/connect
+2. Server sends "connected" message
+3. Client joins room: {"action": "join", "data": {"room": "downloads"}}
+4. ProgressService emits events
+5. WebSocketService broadcasts to room subscribers
+6. Client receives real-time updates
+```
+
+Source: [src/server/api/websocket.py](../src/server/api/websocket.py#L1-L260)
+
+---
+
+## 4. Design Patterns
+
+### 4.1 Repository Pattern (Service Layer as Repository)
+
+**Architecture Decision**: The Service Layer serves as the Repository layer for database access.
+
+Database access is abstracted through service classes in `src/server/database/service.py` that provide CRUD operations and act as the repository layer. This eliminates the need for a separate repository layer while maintaining clean separation of concerns.
+
+**Service Layer Classes** (acting as repositories):
+
+- `AnimeSeriesService` - CRUD operations for anime series
+- `EpisodeService` - CRUD operations for episodes
+- `DownloadQueueService` - CRUD operations for download queue
+- `UserSessionService` - CRUD operations for user sessions
+- `SystemSettingsService` - CRUD operations for system settings
+
+**Key Principles**:
+
+1. **No Direct Database Queries**: Controllers and business logic services MUST use service layer methods
+2. **Service Layer Encapsulation**: All SQLAlchemy queries are encapsulated in service methods
+3. **Consistent Interface**: Services provide consistent async methods for all database operations
+4. **Single Responsibility**: Each service manages one entity type
+
+**Example Usage**:
+
+```python
+# CORRECT: Use service layer
+from src.server.database.service import AnimeSeriesService
+
+async with get_db_session() as db:
+    series = await AnimeSeriesService.get_by_key(db, "attack-on-titan")
+    await AnimeSeriesService.update(db, series.id, has_nfo=True)
+
+# INCORRECT: Direct database query
+result = await db.execute(select(AnimeSeries).filter(...))  # ❌ Never do this
+```
+
+**Special Case - Queue Repository Adapter**:
+
+The `QueueRepository` in `src/server/services/queue_repository.py` is an adapter that wraps `DownloadQueueService` to provide domain model conversion between Pydantic models and SQLAlchemy models:
+
+```python
+# QueueRepository provides CRUD with model conversion
+class QueueRepository:
+    async def save_item(self, item: DownloadItem) -> None: ...  # Converts Pydantic → SQLAlchemy
+    async def get_all_items(self) -> List[DownloadItem]: ...    # Converts SQLAlchemy → Pydantic
+    async def delete_item(self, item_id: str) -> bool: ...
+```
+

+
+### 4.2 Dependency Injection
+
+FastAPI's `Depends()` provides constructor injection.
+
+```python
+@router.get("/status")
+async def get_status(
+    download_service: DownloadService = Depends(get_download_service),
+):
+    ...
+```
+
+Source: [src/server/utils/dependencies.py](../src/server/utils/dependencies.py)
+
+### 4.3 Event-Driven Architecture
+
+Progress updates use an event subscription model.
+
+```python
+# ProgressService publishes events
+progress_service.emit("progress_updated", event)
+
+# WebSocketService subscribes
+progress_service.subscribe("progress_updated", ws_handler)
+```
+
+Source: [src/server/fastapi_app.py](../src/server/fastapi_app.py#L98-L108)
+
+### 4.4 Singleton Pattern
+
+Services use module-level singletons for shared state.
+
+```python
+# In download_service.py
+_download_service_instance: Optional[DownloadService] = None
+
+def get_download_service() -> DownloadService:
+    global _download_service_instance
+    if _download_service_instance is None:
+        _download_service_instance = DownloadService(...)
+    return _download_service_instance
+```
+
+### 4.5 Error Handling Pattern
+
+**Architecture Decision**: Dual error handling approach based on exception source.
+
+The application uses two complementary error handling mechanisms:
+
+1. **FastAPI HTTPException** - For simple validation and HTTP-level errors
+2. **Custom Exception Hierarchy** - For business logic and service-level errors with rich context
+
+#### Exception Hierarchy
+
+```python
+# Base exception with HTTP status mapping
+AniWorldAPIException(message, status_code, error_code, details)
+├── AuthenticationError (401)
+├── AuthorizationError (403)
+├── ValidationError (422)
+├── NotFoundError (404)
+├── ConflictError (409)
+├── BadRequestError (400)
+├── RateLimitError (429)
+└── ServerError (500)
+    ├── DownloadError
+    ├── ConfigurationError
+    ├── ProviderError
+    └── DatabaseError
+```
+
+#### When to Use Each
+
+**Use HTTPException for:**
+
+- Simple parameter validation (missing fields, wrong type)
+- Direct HTTP-level errors (401, 403, 404 without business context)
+- Quick endpoint-specific failures
+
+**Use Custom Exceptions for:**
+
+- Service-layer business logic errors (AnimeServiceError, ConfigServiceError)
+- Errors needing rich context (details dict, error codes)
+- Errors that should be logged with specific categorization
+- Cross-cutting concerns (authentication, authorization, rate limiting)
+
+**Example:**
+
+```python
+# Simple validation - Use HTTPException
+if not series_key:
+    raise HTTPException(status_code=400, detail="series_key required")
+
+# Business logic error - Use custom exception
+try:
+    await anime_service.add_series(series_key)
+except AnimeServiceError as e:
+    raise ServerError(
+        message=f"Failed to add series: {e}",
+        error_code="ANIME_ADD_FAILED",
+        details={"series_key": series_key}
+    )
+```
+
+#### Global Exception Handlers
+
+All custom exceptions are automatically handled by global middleware that:
+
+- Converts exceptions to structured JSON responses
+- Logs errors with appropriate severity
+- Includes request ID for tracking
+- Provides consistent error format

+## 5. Data Flow
+
+### 5.1 Series Identifier Convention
+
+The system uses two identifier fields:
+
+| Field    | Type     | Purpose                                | Example                    |
+| -------- | -------- | -------------------------------------- | -------------------------- |
+| `key`    | Primary  | Provider-assigned, URL-safe identifier | `"attack-on-titan"`        |
+| `folder` | Metadata | Filesystem folder name (display only)  | `"Attack on Titan (2013)"` |
+
+All API operations use `key`. The `folder` is for filesystem operations only.
+
+Source: [src/server/database/models.py](../src/server/database/models.py#L26-L50)
+
+### 5.2 Database Schema
+
+```
++----------------+       +----------------+       +--------------------+
+|  anime_series  |       |    episodes    |       | download_queue_item|

+| key (unique)   |   |   | series_id (FK) |---+   | series_id (FK)     |
+| name           |   +---| season         |       | status             |
+| site           |       | episode_number |       | priority           |

+## 7. Scalability Considerations
+
+### Current Limitations
+
+1. **Single-process deployment**: In-memory rate limiting and session state are not shared across processes.
+
+2. **SQLite database**: Not suitable for high concurrency. Consider PostgreSQL for production.
+
+3. **Sequential downloads**: Only one download processes at a time by design.
+
+### Recommended Improvements for Scale
+
+| Concern        | Current         | Recommended       |
+| -------------- | --------------- | ----------------- |
+| Rate limiting  | In-memory dict  | Redis             |
+| Session store  | In-memory       | Redis or database |
+| Database       | SQLite          | PostgreSQL        |
+| Task queue     | In-memory deque | Celery + Redis    |
+| Load balancing | None            | Nginx/HAProxy     |
+
+---
+
+## 8. Integration Points
+
+### 8.1 External Providers
+
+The system integrates with anime streaming providers via the Loader interface.
+
+```python
+class Loader(ABC):
+    @abstractmethod
+    def search(self, query: str) -> List[Serie]: ...
+
+    @abstractmethod
+    def get_episodes(self, serie: Serie) -> Dict[int, List[int]]: ...
+```
+
+Source: [src/core/providers/base_provider.py](../src/core/providers/base_provider.py)
+
+### 8.2 Filesystem Integration
+
+The scanner reads anime directories to detect downloaded episodes.
+
+```python
+SerieScanner(
+    basePath="/path/to/anime",  # Anime library directory
+    loader=provider,             # Provider for metadata
+    db_session=session           # Optional database
+)
+```
+
+Source: [src/core/SerieScanner.py](../src/core/SerieScanner.py#L59-L96)
+
+---
+
+## 9. Security Architecture
+
+### 9.1 Authentication Flow
+
+```
+1. User sets master password via POST /api/auth/setup
+2. Password hashed with pbkdf2_sha256 (via passlib)
+3. Hash stored in config.json
+4. Login validates password, returns JWT token
+5. JWT contains: session_id, user, created_at, expires_at
+6. Subsequent requests include: Authorization: Bearer <token>
+```
+
+Source: [src/server/services/auth_service.py](../src/server/services/auth_service.py#L1-L150)
+
+### 9.2 Password Requirements
+
+- Minimum 8 characters
+- Mixed case (upper and lower)
+- At least one number
+- At least one special character
+
+Source: [src/server/services/auth_service.py](../src/server/services/auth_service.py#L97-L125)
+
+### 9.3 Rate Limiting
+
+| Endpoint          | Limit       | Window     |
+| ----------------- | ----------- | ---------- |
+| `/api/auth/login` | 5 requests  | 60 seconds |
+| `/api/auth/setup` | 5 requests  | 60 seconds |
+| All origins       | 60 requests | 60 seconds |

+## Format
+
+This changelog follows [Keep a Changelog](https://keepachangelog.com/) principles and adheres to [Semantic Versioning](https://semver.org/).
+
+---
+
+## [1.3.1] - 2026-02-22
+
+### Added
+
+- **Temp file cleanup after every download** (`src/core/providers/aniworld_provider.py`,
+  `src/core/providers/enhanced_provider.py`): Module-level helper
+  `_cleanup_temp_file()` removes the working temp file and any yt-dlp `.part`
+  fragments after each download attempt — on success, on failure, and on
+  exceptions (including `BrokenPipeError` and cancellation). Ensures that no
+  partial files accumulate in `./Temp/` across multiple runs.
+- **Temp folder purge on server start** (`src/server/fastapi_app.py`): The
+  FastAPI lifespan startup now iterates `./Temp/` and deletes every file and
+  sub-directory before the rest of the initialisation sequence runs. If the
+  folder does not exist it is created. Errors are caught and logged as warnings
+  so that they never abort startup.
+
+---
+
+## [1.3.0] - 2026-02-22
+
+### Added
+
+- **NFO tag completeness (`nfo_mapper.py`)**: All 17 required NFO tags are now
+  explicitly populated during creation: `originaltitle`, `sorttitle`, `year`,
+  `plot`, `outline`, `tagline`, `runtime`, `premiered`, `status`, `imdbid`,
+  `genre`, `studio`, `country`, `actor`, `watched`, `dateadded`, `mpaa`.
+- **`src/core/utils/nfo_mapper.py`**: New module containing
+  `tmdb_to_nfo_model()`, `_extract_rating_by_country()`, and
+  `_extract_fsk_rating()`. Extracted from `NFOService` to keep files under
+  500 lines and isolate pure mapping logic.
+- **US MPAA rating**: `_extract_rating_by_country(ratings, "US")` now maps the
+  US TMDB content rating to the `<mpaa>` NFO tag.
+- **`NfoRepairService` (`src/core/services/nfo_repair_service.py`)**: New service
+  that detects incomplete `tvshow.nfo` files and triggers TMDB re-fetch.
+  Provides `parse_nfo_tags()`, `find_missing_tags()`, `nfo_needs_repair()`, and
+  `NfoRepairService.repair_series()`. 13 required tags are checked.
+- **`perform_nfo_repair_scan()` startup hook
+  (`src/server/services/initialization_service.py`)**: New async function
+  called during application startup. Iterates every series directory, checks
+  whether `tvshow.nfo` is missing required tags using `nfo_needs_repair()`, and
+  either queues the series for background reload (when a `background_loader` is
+  provided) or calls `NfoRepairService.repair_series()` directly. Skips
+  gracefully when `tmdb_api_key` or `anime_directory` is not configured.
+- **NFO repair wired into startup lifespan (`src/server/fastapi_app.py`)**:
+  `perform_nfo_repair_scan(background_loader)` is called at the end of the
+  FastAPI lifespan startup, after `perform_media_scan_if_needed`, ensuring
+  every existing series NFO is checked and repaired on each server start.
+
+### Changed
+
+- `NFOService._tmdb_to_nfo_model()` and `NFOService._extract_fsk_rating()` moved
+  to `src/core/utils/nfo_mapper.py` as module-level functions
+  `tmdb_to_nfo_model()` and `_extract_fsk_rating()`.
+- `src/core/services/nfo_service.py` reduced from 640 → 471 lines.
+
+---
+
+## [Unreleased] - 2026-01-18
+
+### Added
+
+- **Cron-based Scheduler**: Replaced the asyncio sleep-loop with APScheduler's `AsyncIOScheduler + CronTrigger`
+    - Schedule rescans at a specific **time of day** (`HH:MM`) on selected **days of the week**
+    - New `SchedulerConfig` fields: `schedule_time` (default `"03:00"`), `schedule_days` (default all 7), `auto_download_after_rescan` (default `false`)
+    - Old `interval_minutes` field retained for backward compatibility
+- **Auto-download after rescan**: When `auto_download_after_rescan` is enabled, missing episodes are automatically queued for download after each scheduled rescan
+- **Day-of-week UI**: New day-of-week pill toggles (Mon–Sun) in the Settings → Scheduler section
+- **Live config reload**: POST `/api/scheduler/config` reschedules the APScheduler job without restarting the application
+- **Enriched API response**: GET/POST `/api/scheduler/config` now returns `{"success", "config", "status"}` envelope including `next_run`, `last_run`, and `scan_in_progress`
+
+### Changed
+
+- Scheduler API response format: previously returned flat config; now returns `{"success": true, "config": {...}, "status": {...}}`
+- `reload_config()` is now a synchronous method accepting a `SchedulerConfig` argument (previously async, no arguments)
+- Dependencies: added `APScheduler>=3.10.4` to `requirements.txt`
+
+### Fixed
+
+- **Series Visibility**: Fixed issue where series added to the database weren't appearing in the API/UI
+    - Series are now loaded from database into SeriesApp's in-memory cache on startup
+    - Added `_load_series_from_db()` call after initial database sync in FastAPI lifespan
+- **Episode Tracking**: Fixed missing episodes not being saved to database when adding new series
+    - Missing episodes are now persisted to the `episodes` table after the targeted scan
+    - Episodes are properly synced during rescan operations (added/removed based on filesystem state)
+- **Database Synchronization**: Improved data consistency between database and in-memory cache
+    - Rescan process properly updates episodes: adds new missing episodes, removes downloaded ones
+    - All series operations now maintain database and cache synchronization
+
+### Technical Details
+
+- Modified `src/server/fastapi_app.py` to load series from database after sync
+- Modified `src/server/api/anime.py` to save scanned episodes to database
+- Episodes table properly tracks missing episodes with automatic cleanup

+# Configuration Reference
+
+## Document Purpose
+
+This document provides a comprehensive reference for all configuration options in the Aniworld application.
+
+---
+
+## 1. Configuration Overview
+
+### Configuration Sources
+
+Aniworld uses a layered configuration system with **explicit precedence rules**:
+
+1. **Environment Variables** (highest priority) - Takes precedence over all other sources
+2. **`.env` file** in project root - Loaded as environment variables
+3. **`data/config.json`** file - Persistent file-based configuration
+4. **Default values** (lowest priority) - Built-in fallback values
+
+### Precedence Rules
+
+**Critical Principle**: `ENV VARS > config.json > defaults`
+
+- **Environment variables always win**: If a value is set via environment variable, it will NOT be overridden by config.json
+- **config.json as fallback**: If an ENV var is not set (or is empty/default), the value from config.json is used
+- **Defaults as last resort**: Built-in default values are used only if neither ENV var nor config.json provide a value
+
+### Loading Mechanism
+
+Configuration is loaded at application startup in `src/server/fastapi_app.py`:
+
+1. **Pydantic Settings** loads ENV vars and .env file with defaults
+2. **config.json** is loaded via `ConfigService`
+3. **Selective sync**: config.json values sync to settings **only if** ENV var not set
+4. **Runtime access**: Code uses `settings` object (which has final merged values)
+
+**Example**:
+
+```bash
+# If ENV var is set:
+ANIME_DIRECTORY=/env/path  # This takes precedence
+
+# config.json has:
+{"other": {"anime_directory": "/config/path"}}  # This is ignored
+
+# Result: settings.anime_directory = "/env/path"

+
+### 4.6 Other Settings (Dynamic)
+
+The `other` field stores arbitrary settings.
+
+| Key                    | Type   | Description                             |
+| ---------------------- | ------ | --------------------------------------- |

+| `advanced`             | object | Advanced configuration options.         |
+
+---
+
+## 5. Configuration Precedence
+
+Settings are resolved in this order (first match wins):
+
+1. Environment variable (e.g., `ANIME_DIRECTORY`)
+2. `.env` file in project root
+3. `data/config.json` (for dynamic settings)
+4. Code defaults in `Settings` class
+
+---
+
+## 6. Validation Rules
+
+### Password Requirements
+
+Master password must meet all criteria:
+
+- Minimum 8 characters
+- At least one uppercase letter
+- At least one lowercase letter
+- At least one digit
+- At least one special character
+
+Source: [src/server/services/auth_service.py](../src/server/services/auth_service.py#L97-L125)
+
+### Logging Level Validation
+
+Must be one of: `DEBUG`, `INFO`, `WARNING`, `ERROR`, `CRITICAL`
+
+Source: [src/server/models/config.py](../src/server/models/config.py#L43-L47)
+
+### Backup Path Validation
+
+If `backup.enabled` is `true`, `backup.path` must be set.
+
+Source: [src/server/models/config.py](../src/server/models/config.py#L87-L91)
+
+---
+
+## 7. Example Configurations
+
+### Minimal Development Setup
+
+**.env file:**
+
+```
+LOG_LEVEL=DEBUG
+ANIME_DIRECTORY=/home/user/anime
+```
+
+### Production Setup
+
+**.env file:**
+
+```
+JWT_SECRET_KEY=your-secure-random-key-here
+DATABASE_URL=postgresql+asyncpg://user:pass@localhost/aniworld
+LOG_LEVEL=WARNING
+CORS_ORIGINS=https://your-domain.com
+API_RATE_LIMIT=60
+```
+
+### Docker Setup
+
+```yaml
+# docker-compose.yml
+environment:
+    - JWT_SECRET_KEY=${JWT_SECRET_KEY}
+    - DATABASE_URL=sqlite:///./data/aniworld.db
+    - ANIME_DIRECTORY=/media/anime
+    - LOG_LEVEL=INFO
+volumes:
+    - ./data:/app/data
+    - /media/anime:/media/anime:ro
+```
+
+---
+
+## 8. Configuration Backup Management
+
+### Automatic Backups
+
+Backups are created automatically before config changes when `backup.enabled` is `true`.
+
+Location: `data/config_backups/`
+
+Naming: `config_backup_YYYYMMDD_HHMMSS.json`
+
+### Manual Backup via API
+
+```bash
+# Create backup
+curl -X POST http://localhost:8000/api/config/backups \
+  -H "Authorization: Bearer $TOKEN"
+
+# List backups
+curl http://localhost:8000/api/config/backups \
+  -H "Authorization: Bearer $TOKEN"
+
+# Restore backup
+curl -X POST http://localhost:8000/api/config/backups/config_backup_20251213.json/restore \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+Source: [src/server/api/config.py](../src/server/api/config.py#L67-L142)
+
+---
+
+## 9. Troubleshooting
+
+### Configuration Not Loading
+
+1. Check file permissions on `data/config.json`
+2. Verify JSON syntax with a validator
+3. Check logs for Pydantic validation errors
+
+### Environment Variable Not Working
+
+1. Ensure variable name matches exactly (case-sensitive)
+2. Check `.env` file location (project root)
+3. Restart application after changes
+
+### Master Password Issues
+
+1. Password hash is stored in `config.json` under `other.master_password_hash`
+2. Delete this field to reset (requires re-setup)
+3. Check hash format starts with `$pbkdf2-sha256$`

+
+**Purpose:**
+
+This table tracks the initialization status of the application to ensure that expensive one-time setup operations (like scanning the entire anime directory) only run on the first startup, not on every restart.
+
+- Only one row exists in this table
+- The `initial_scan_completed` flag prevents redundant full directory scans on each startup
+- The NFO and media scan flags similarly track completion of those setup tasks

+## 6. Transaction Support
+
+### 6.1 Overview
+
+The database layer provides comprehensive transaction support to ensure data consistency across compound operations. All write operations can be wrapped in explicit transactions.
+
+Source: [src/server/database/transaction.py](../src/server/database/transaction.py)
+
+### 6.2 Transaction Utilities
+
+| Component                 | Type              | Description                              |
+| ------------------------- | ----------------- | ---------------------------------------- |
+| `@transactional`          | Decorator         | Wraps function in transaction boundary   |
+| `atomic()`                | Async context mgr | Provides atomic operation block          |
+| `atomic_sync()`           | Sync context mgr  | Sync version of atomic()                 |
+| `TransactionContext`      | Class             | Explicit sync transaction control        |
+| `AsyncTransactionContext` | Class             | Explicit async transaction control       |
+| `TransactionManager`      | Class             | Helper for manual transaction management |
+
+### 6.3 Transaction Propagation Modes
+
+| Mode           | Behavior                                         |
+| -------------- | ------------------------------------------------ |
+| `REQUIRED`     | Use existing transaction or create new (default) |
+| `REQUIRES_NEW` | Always create new transaction                    |
+| `NESTED`       | Create savepoint within existing transaction     |
+
+### 6.4 Usage Examples
+
+**Using @transactional decorator:**
+
+```python
+from src.server.database.transaction import transactional
+
+@transactional()
+async def compound_operation(db: AsyncSession, data: dict):
+    # All operations commit together or rollback on error
+    series = await AnimeSeriesService.create(db, ...)
+    episode = await EpisodeService.create(db, series_id=series.id, ...)
+    return series, episode
+```
+
+**Using atomic() context manager:**
+
+```python
+from src.server.database.transaction import atomic
+
+async def some_function(db: AsyncSession):
+    async with atomic(db) as tx:
+        await operation1(db)
+        await operation2(db)
+        # Auto-commits on success, rolls back on exception
+```
+
+**Using savepoints for partial rollback:**
+
+```python
+async with atomic(db) as tx:
+    await outer_operation(db)
+
+    async with tx.savepoint() as sp:
+        await risky_operation(db)
+        if error_condition:
+            await sp.rollback()  # Only rollback nested ops
+
+    await final_operation(db)  # Still executes
+```

+
+### 6.5 Connection Module Additions
+
+| Function                        | Description                                  |
+| ------------------------------- | -------------------------------------------- |
+| `get_transactional_session`     | Session without auto-commit for transactions |
+| `TransactionManager`            | Helper class for manual transaction control  |
+| `is_session_in_transaction`     | Check if session is in active transaction    |
+| `get_session_transaction_depth` | Get nesting depth of transactions            |
+
+Source: [src/server/database/connection.py](../src/server/database/connection.py)
+
+---
+
+## 7. Repository Pattern
+
+The `QueueRepository` class provides data access abstraction.
+
+```python
+class QueueRepository:
+    async def save_item(self, item: DownloadItem) -> None:
+        """Save or update a download item (atomic operation)."""
+
+    async def get_all_items(self) -> List[DownloadItem]:
+        """Get all items from database."""
+
+    async def delete_item(self, item_id: str) -> bool:
+        """Delete item by ID."""
+
+    async def clear_all(self) -> int:
+        """Clear all items (atomic operation)."""
+```
+
+Note: Compound operations (`save_item`, `clear_all`) are wrapped in `atomic()` transactions.
+
+Source: [src/server/services/queue_repository.py](../src/server/services/queue_repository.py)
+
+---
+
+## 8. Database Service
+
+The `AnimeSeriesService` provides async CRUD operations.
+
+```python
+class AnimeSeriesService:
+    @staticmethod
+    async def create(
+        db: AsyncSession,
+        key: str,
+        name: str,
+        site: str,
+        folder: str
+    ) -> AnimeSeries:
+        """Create a new anime series."""
+
+    @staticmethod
+    async def get_by_key(
+        db: AsyncSession,
+        key: str
+    ) -> Optional[AnimeSeries]:
+        """Get series by primary key identifier."""
+```
+
+### Bulk Operations
+
+Services provide bulk operations for transaction-safe batch processing:
+
+| Service                | Method                 | Description                    |
+| ---------------------- | ---------------------- | ------------------------------ |
+| `EpisodeService`       | `bulk_mark_downloaded` | Mark multiple episodes at once |
+| `DownloadQueueService` | `bulk_delete`          | Delete multiple queue items    |
+| `DownloadQueueService` | `clear_all`            | Clear entire queue             |
+| `UserSessionService`   | `rotate_session`       | Revoke old + create new atomic |
+| `UserSessionService`   | `cleanup_expired`      | Bulk delete expired sessions   |
+
+Source: [src/server/database/service.py](../src/server/database/service.py)
+
+---
+
+## 9. Data Integrity Rules
+
+### Validation Constraints
+
+| Field                     | Rule                     | Error Message                         |
+| ------------------------- | ------------------------ | ------------------------------------- |
+| `anime_series.key`        | Non-empty, max 255 chars | "Series key cannot be empty"          |
+| `anime_series.name`       | Non-empty, max 500 chars | "Series name cannot be empty"         |
+| `episodes.season`         | 0-1000                   | "Season number must be non-negative"  |
+| `episodes.episode_number` | 0-10000                  | "Episode number must be non-negative" |
+
+Source: [src/server/database/models.py](../src/server/database/models.py#L89-L119)
+
+### Cascade Rules
+
+- Deleting `anime_series` deletes all related `episodes` and `download_queue_item`
+
+---
+
+## 10. Migration Strategy
+
+Currently, SQLAlchemy's `create_all()` is used for schema creation.
+
+```python
+# src/server/database/connection.py
+async def init_db():
+    async with engine.begin() as conn:
+        await conn.run_sync(Base.metadata.create_all)
+```
+
+For production migrations, Alembic is recommended but not yet implemented.
+
+Source: [src/server/database/connection.py](../src/server/database/connection.py)
+
+---
+
+## 11. Common Query Patterns
+
+### Get all series with missing episodes
+
+```python
+series = await db.execute(
+    select(AnimeSeries).options(selectinload(AnimeSeries.episodes))
+)
+for serie in series.scalars():
+    downloaded = [e for e in serie.episodes if e.is_downloaded]
+```
+
+### Get pending downloads ordered by priority
+
+```python
+items = await db.execute(
+    select(DownloadQueueItem)
+    .where(DownloadQueueItem.status == "pending")
+    .order_by(
+        case(
+            (DownloadQueueItem.priority == "HIGH", 1),
+            (DownloadQueueItem.priority == "NORMAL", 2),
+            (DownloadQueueItem.priority == "LOW", 3),
+        ),
+        DownloadQueueItem.added_at
+    )
+)
+```
+
+---
+
+## 12. Database Location
+
+| Environment | Default Location                                  |
+| ----------- | ------------------------------------------------- |
+| Development | `./data/aniworld.db`                              |
+| Production  | Via `DATABASE_URL` environment variable           |
+| Testing     | In-memory SQLite (`sqlite+aiosqlite:///:memory:`) |

+### Features
+
+- **Automatic NFO Creation**: Generate NFO files during downloads
+- **TMDB Integration**: Fetch metadata from The Movie Database
+- **Image Downloads**: Poster, fanart, and logo images
+- **Batch Operations**: Create/update NFO files for multiple anime
+- **Web UI**: Manage NFO settings and operations
+- **API Access**: Programmatic NFO management

+
+## 6. Troubleshooting
+
+### 6.1 NFO Files Not Created
+
+**Problem**: NFO files are not being created during downloads.
+
+**Solutions**:
+
+1. Verify TMDB API key is configured correctly
+2. Check `auto_create` is enabled in settings
+3. Ensure anime directory has write permissions
+4. Check logs for error messages
+5. Test TMDB connection using "Test Connection" button
+
+### 6.2 Invalid TMDB API Key
+
+**Problem**: TMDB validation fails with "Invalid API key".
+
+**Solutions**:
+
+1. Verify API key is copied correctly (no extra spaces)
+2. Ensure you're using the v3 API key (not v4)
+3. Check API key is active on TMDB website
+4. Try regenerating API key on TMDB
+
+### 6.3 Images Not Downloading
+
+**Problem**: NFO files are created but images are missing.
+
+**Solutions**:
+
+1. Enable image downloads in settings (poster/logo/fanart)
+2. Verify TMDB API key is valid
+3. Check network connectivity to TMDB servers
+4. Ensure sufficient disk space
+5. Check file permissions in anime directory
+
+### 6.4 Incorrect Metadata
+
+**Problem**: NFO contains wrong show information.
+
+**Solutions**:
+
+1. Verify anime title matches TMDB exactly
+2. Use TMDB ID if available for accurate matching
+3. Update NFO files with `force=true` to refresh metadata
+4. Check TMDB website for correct show information
+
+### 6.5 Permission Errors
+
+**Problem**: "Permission denied" when creating NFO files.
+
+**Solutions**:
+
+1. Check anime directory permissions: `chmod 755 /path/to/anime`
+2. Ensure application user has write access
+3. Verify directory ownership: `chown -R user:group /path/to/anime`
+4. Check parent directories are accessible
+
+### 6.6 Slow NFO Creation
+
+**Problem**: NFO creation takes a long time.
+
+**Solutions**:
+
+1. Reduce image size (use w500 instead of original)
+2. Disable unnecessary images (logo, fanart)
+3. Create NFOs in batches during off-peak hours
+4. Check network speed to TMDB servers
+5. Verify disk I/O performance
+
+---
+
+## 7. Best Practices
+
+### 7.1 Configuration Recommendations
+
+- **Image Size**: Use `w500` for optimal balance of quality and storage
+- **Auto-create**: Enable for new downloads
+- **Update on scan**: Disable to avoid unnecessary TMDB API calls
+- **Poster**: Always enable for show and episode thumbnails
+- **Logo/Fanart**: Enable only if your media server supports them
+
+### 7.2 Maintenance
+
+- **Regular Updates**: Update NFO files quarterly to get latest metadata
+- **Backup**: Include NFO files in your backup strategy
+- **Validation**: Periodically check missing NFOs using `/api/nfo/missing`
+- **API Rate Limits**: Be mindful of TMDB API rate limits when batch processing
+
+### 7.3 Performance
+
+- **Batch Operations**: Use batch endpoints for multiple anime
+- **Off-Peak Processing**: Create NFOs during low-activity periods
+- **Image Optimization**: Use smaller image sizes for large libraries
+- **Selective Updates**: Only update NFOs when metadata changes
+
+### 7.4 Media Server Integration
+
+#### Plex
+
+- Use "Personal Media Shows" agent
+- Enable "Local Media Assets" scanner
+- Place NFO files in anime directories
+- Refresh metadata after creating NFOs
+
+#### Jellyfin
+
+- Use "NFO" metadata provider
+- Enable in Library settings
+- Order providers: NFO first, then online sources
+- Scan library after NFO creation
+
+#### Emby
+
+- Enable "NFO" metadata reader
+- Configure in Library advanced settings
+- Use "Prefer embedded metadata" option
+- Refresh metadata after updates
+
+#### Kodi
+
+- NFO files are automatically detected
+- No additional configuration needed
+- Update library to see changes
+
+---
+
+## 8. Advanced Usage
+
+### 8.1 Custom NFO Templates
+
+You can customize NFO generation by modifying the NFO service:
+
+```python
+# src/core/services/nfo_creator.py
+def generate_tvshow_nfo(self, metadata: dict) -> str:
+    # Add custom fields or modify structure
+    pass
+```
+
+### 8.2 Bulk Operations
+
+Create NFOs for entire library:
+
+```bash
+# Get all anime without NFOs
+curl -X GET "http://127.0.0.1:8000/api/nfo/missing" \
+  -H "Authorization: Bearer $TOKEN" \
+  | jq -r '.anime_list[].anime_id' \
+  | xargs -I{} curl -X POST "http://127.0.0.1:8000/api/nfo/batch/create" \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"anime_ids": [{}]}'
+```
+
+### 8.3 Scheduled Updates
+
+Use the scheduler API to refresh NFOs automatically:
+
+```bash
+# Schedule weekly NFO updates (rescan runs Sunday at 03:00)
+curl -X POST "http://127.0.0.1:8000/api/scheduler/config" \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "enabled": true,
+    "schedule_time": "03:00",
+    "schedule_days": ["sun"],
+    "auto_download_after_rescan": false
+  }'
+```

+

+
+## 11. Automatic NFO Repair
+
+Every time the server starts, Aniworld scans all existing `tvshow.nfo` files and
+automatically repairs any that are missing required tags.
+
+### How It Works
+
+1. **Scan** — `perform_nfo_repair_scan()` in
+   `src/server/services/initialization_service.py` is called from the FastAPI
+   lifespan after `perform_media_scan_if_needed()`.
+2. **Detect** — `nfo_needs_repair(nfo_path)` from
+   `src/core/services/nfo_repair_service.py` parses each `tvshow.nfo` with
+   `lxml` and checks for the 13 required tags listed below.
+3. **Repair** — Series whose NFO is incomplete are queued for background reload
+   via `BackgroundLoaderService.add_series_loading_task()`. The background
+   loader re-fetches metadata from TMDB and rewrites the NFO with all tags
+   populated.
+
+### Tags Checked (13 required)
+
+| XPath             | Tag name        |
+| ----------------- | --------------- |
+| `./title`         | `title`         |
+| `./originaltitle` | `originaltitle` |

+| ----------------------------------------------------------- | ------------------------------------------------- |
+| `NFO repair scan complete: 0 of N series queued for repair` | All NFOs are complete — no action needed          |
+| `NFO repair scan complete: X of N series queued for repair` | X series had incomplete NFOs and have been queued |
+| `NFO repair scan skipped: TMDB API key not configured`      | Set `tmdb_api_key` in `data/config.json`          |
+| `NFO repair scan skipped: anime directory not configured`   | Set `anime_directory` in `data/config.json`       |
+
+### Triggering a Manual Repair
+
+You can also repair a single series on demand via the API:
+
+```http
+POST /api/nfo/update/{series_key}
+```
+
+This calls `NFOService.update_tvshow_nfo()` directly and overwrites the existing
+`tvshow.nfo` with fresh data from TMDB.

+# Aniworld Web Application Development Instructions
+
+This document provides detailed tasks for AI agents to implement a modern web application for the Aniworld anime download manager. All tasks should follow the coding guidelines specified in the project's copilot instructions.
+
+## Project Overview
+
+The goal is to create a FastAPI-based web application that provides a modern interface for the existing Aniworld anime download functionality. The core anime logic should remain in `SeriesApp.py` while the web layer provides REST API endpoints and a responsive UI.
+
+## Architecture Principles
+
+- **Single Responsibility**: Each file/class has one clear purpose
+- **Dependency Injection**: Use FastAPI's dependency system
+- **Clean Separation**: Web layer calls core logic, never the reverse
+- **File Size Limit**: Maximum 500 lines per file
+- **Type Hints**: Use comprehensive type annotations
+- **Error Handling**: Proper exception handling and logging
+
+## Additional Implementation Guidelines
+
+### Code Style and Standards
+
+- **Type Hints**: Use comprehensive type annotations throughout all modules
+- **Docstrings**: Follow PEP 257 for function and class documentation
+- **Error Handling**: Implement custom exception classes with meaningful messages
+- **Logging**: Use structured logging with appropriate log levels
+- **Security**: Validate all inputs and sanitize outputs
+- **Performance**: Use async/await patterns for I/O operations
+
+## 📞 Escalation
+
+If you encounter:
+
+- Architecture issues requiring design decisions
+- Tests that conflict with documented requirements
+- Breaking changes needed
+- Unclear requirements or expectations
+
+**Document the issue and escalate rather than guessing.**

-## Authentication & Setup Flow
-
-### Application Initialization Flow
-
--   **Setup Page**: Display application setup page when the application is run for the first time and no configuration exists
-
-    -   Check for presence of configuration file/database setup
-    -   Guide user through initial application configuration
-    -   Set up database connections, initial admin user, and core settings
-    -   Mark setup as completed in configuration
-
--   **Authentication Gate**: Redirect to authentication page when user token is invalid or missing
-
-    -   Validate existing authentication tokens
-    -   Display login/registration interface for unauthenticated users
-    -   Handle token refresh and session management
-    -   Redirect authenticated users to main application
-
--   **Main Application**: Show index.html for authenticated users with valid tokens
-    -   Display main application interface
-    -   Provide access to all authenticated user features
-    -   Maintain session state and handle token expiration gracefully
-
-### User Flow Priority
-
-1. Check if application setup is completed → Show setup page if not
-2. Check if user is authenticated → Show auth page if not
-3. Show main application (index.html) for authenticated users
-
