+
+## Project Overview
+
+Twitch Drops Miner is a Python application that automatically mines timed Twitch drops without downloading stream data. It uses Twitch's GraphQL API and websocket connections to simulate watching streams while tracking drop progress.
+
+**Key Characteristics:**
+
+- Python 3.10+ required
+- Web-based GUI using FastAPI and Socket.IO
+- Async/await architecture with asyncio
+- Session persistence via cookies
+- No stream video/audio download (bandwidth-efficient)
+- Docker-ready for easy deployment
+
+## Development Commands
+
+**IMPORTANT: Always activate the virtual environment first!**
+
+The project uses a virtual environment located at `env/`. All Python commands must be run within this environment:
+
+```bash
+# Activate the virtual environment (required before any Python commands)
+source env/bin/activate
+```
+
+### Running the Application
+
+```bash
+# Run from source (remember to activate venv first!)
+source env/bin/activate && python main.py
+
+# With verbose logging (stackable: -vv, -vvv)
+source env/bin/activate && python main.py -v
+
+# Create data dump for debugging
+source env/bin/activate && python main.py --dump
+
+# Access the web interface at http://localhost:8080
+```
+
+### Development Setup
+
+The application requires:
+
+- Python 3.10+
+- Virtual environment at `env/` (must be activated before running commands)
+- Dependencies from `pyproject.toml` (includes FastAPI, uvicorn, Socket.IO)
+
+Docker deployment:
+
+```bash
+# Build and run with docker-compose
+docker-compose up -d
+
+# Access at http://localhost:8080
+```
+
+## Architecture

+
+### Core Components
+
+**main.py** - Simple launcher:
+
+- Runs the `src` package as a module using `runpy.run_module("src")`
+- All application logic is now in `src/__main__.py`
+
+**src/__main__.py** - Entry point:
+
+- Parses command-line arguments
+- Initializes Settings, Twitch client, and WebGUIManager
+- Starts the FastAPI web server (uvicorn on port 8080)
+- Runs the main asyncio event loop
+- Handles signals (SIGINT, SIGTERM on Linux) and exit codes
+
+**src/core/client.py** - Central client (`Twitch` class):
+
+- State machine: IDLE, INVENTORY_FETCH, GAMES_UPDATE, CHANNELS_CLEANUP, CHANNELS_FETCH, CHANNEL_SWITCH, EXIT
+- Composes `_AuthState`, `HTTPClient`, and `GQLClient`
+- Delegates to service layer for business logic
+- Drop progress monitoring via periodic "watch" payloads
+- Manages WebsocketPool and maintenance tasks
+
+**src/services/** - Business logic layer (fully implemented):
+
+- `ChannelService`: Channel management and selection logic
+- `InventoryService`: Campaign and drop inventory operations
+- `WatchService`: Drop mining watch payload logic
+- `MaintenanceService`: Periodic maintenance tasks
+- `MessageHandlerService`: Websocket message routing and handling
+
+
+**src/models/channel.py** - Channel and Stream:
+
+- `Channel` class: Twitch channel with online/offline status
+- `Stream` class: Active stream with game, viewers, drop status
+- Stream URL fetching and validation
+- ACL-based vs directory channels
+
+**src/models/campaign.py** - Drop campaigns:
+
+- `DropsCampaign`: Campaign with game, timeframe, allowed channels
+- Time-based eligibility and progress tracking
+
+**src/models/drop.py** - Drop types:
+
+- `TimedDrop`: Drops with minute requirements and progress
+- `BaseDrop`: Base class with claim logic
+- Precondition chains for sequential drops
+
+**src/web/gui_manager.py** - Web GUI:
+
+- `WebGUIManager`: Main GUI coordinator
+- Composes individual managers for different UI concerns (status, console, channels, campaigns, inventory, login, settings, cache)
+- Uses `WebSocketBroadcaster` for real-time Socket.IO updates
+- Pure asyncio, no tkinter dependency
+
+**src/web/app.py** - FastAPI application:
+
+- REST API endpoints: `/api/status`, `/api/channels`, `/api/campaigns`, `/api/settings`, `/api/login`, `/api/oauth/confirm`, `/api/reload`, `/api/close`
+- Socket.IO server for real-time bi-directional communication
+- Serves static web frontend from `web/` directory
+- Integrates with WebGUIManager via `set_managers()`
+
+**src/websocket/pool.py** - WebSocket management:
+
+- Sharded connections (up to 50 topics per socket, max 199 channels)
+- Topics: User.Drops, User.Notifications, Channel.StreamState, Channel.StreamUpdate
+- Automatic reconnection with exponential backoff
+- Message routing to registered callbacks
+
+**src/config/settings.py** - Application settings:
+
+- Games to watch list (auto-populated from available campaigns if empty)
+- Connection quality multiplier
+- Language selection
+- Proxy support (including verification)
+- Logging and dump flags from command-line arguments
+- Persistence to JSON file (`settings.json`) in DATA_DIR
+- Inventory filters (Status, Benefit Type, Game Search)
+
+### State Machine Flow
+
+1. **IDLE** - Waiting for campaigns or user action
+2. **INVENTORY_FETCH** - Fetch campaigns from GraphQL, claim completed drops
+3. **GAMES_UPDATE** - Determine wanted games based on priority/exclude lists
+4. **CHANNELS_CLEANUP** - Remove channels not streaming wanted games
+5. **CHANNELS_FETCH** - Discover channels via ACL lists or game directories
+6. **CHANNEL_SWITCH** - Select best channel to watch based on priority/ACL
+7. Loop between CHANNEL_SWITCH and periodic INVENTORY_FETCH (hourly)
+
+### Authentication
+
+- Uses OAuth device code flow (user enters code at twitch.tv/activate)
+- Managed by `src/auth/auth_state.py` (`_AuthState` class)
+- Access tokens stored in `cookies.jar` in DATA_DIR
+- Device ID from Twitch's `unique_id` cookie
+- Session ID generated per run
+- Client info defined in `src/config/client_info.py` (presents as Android app with Client-Id and User-Agent spoofing)
+
+### Drop Mining Mechanism
+
+The application sends periodic "watch" payloads to a spade URL every ~20 seconds:
+
+- Payload contains minute-watched events with channel/broadcast IDs
+- Twitch reports progress via websocket (User.Drops topic)
+- If websocket updates stop, fallback to GQL CurrentDrop query
+- Extrapolation via "bump minutes" when no updates received
+
+### GraphQL Operations
+
+Defined in `src/config/operations.py` as `GQL_OPERATIONS`:
+
+- **Inventory** - Fetch in-progress campaigns and claimed benefits
+- **Campaigns** - List available active/upcoming campaigns
+- **CampaignDetails** - Detailed drop info for a campaign
+- **GameDirectory** - Find live streams for a game with drops enabled
+- **GetStreamInfo** - Check if channel is online and get stream details
+- **CurrentDrop** - Query currently mined drop progress
+- **ClaimDrop** - Claim a completed drop
+- **AvailableDrops** - Check which campaigns a channel qualifies for (badge validation)
+- **NotificationsDelete** - Delete Twitch notifications
+
+### Channel Selection Priority
+
+1. Selected channel (if user clicked one)
+2. ACL-based channels over directory channels
+3. Game priority order (from settings)
+4. Viewer count (descending)
+5. Maximum 199 channels tracked simultaneously
+
+### Maintenance Task
+
+Runs in background to trigger:
+
+- Channel cleanup when drops start/end (based on time_triggers)
+- Inventory reload every ~60 minutes
+
+### Translation System
+
+**Architecture:**
+
+- All translations stored as JSON files in `lang/` directory (19 languages supported)
+- English (`lang/English.json`) is the single source of truth and fallback language
+- Strongly typed with TypedDict schema defined in `src/i18n/translator.py`
+- Translator class (`src/i18n/translator.py`) handles language loading and fallback
+- Singleton instance `_` available via `from src.i18n import _`
+
+**Supported Languages:**
+
+- English, Dansk (Danish), Deutsch (German), Español (Spanish), Français (French)
+- Indonesian, Italiano (Italian), Nederlandse (Dutch), Polski (Polish), Português (Portuguese)
+- Română (Romanian), Türkçe (Turkish), Čeština (Czech)
+- Русский (Russian), Українська (Ukrainian), العربية (Arabic)
+- 日本語 (Japanese), 简体中文 (Simplified Chinese), 繁體中文 (Traditional Chinese)
+
+**Translation Structure:**
+
+```python
+Translation = {
+    "language_name": str,      # Display name of language
+    "english_name": str,       # English name of language
+    "status": StatusMessages,  # Console status messages
+    "login": LoginMessages,    # Login-related messages
+    "error": ErrorMessages,    # Error messages
+    "gui": GUIMessages        # All web GUI text (tabs, settings, help, etc.)
+}
+```
+
+**Usage:**
+
+```python
+from src.i18n import _
+
+# Access translations
+status_text = _.t["gui"]["status"]["idle"]  # Returns "Idle"
+login_text = _.t["login"]["status"]["logged_in"]  # Returns "Logged in"
+```
+
+**Language Persistence:**
+
+- Language selection persisted in `settings.json` (DATA_DIR)
+- Dynamic language switching supported in web GUI
+- Changes take effect immediately without restart

+## Testing
+
+### Automated Tests
+
+The project includes a test suite in the `tests/` directory:
+
+```bash
+# Activate virtual environment and run tests
+source env/bin/activate && python -m pytest tests/
+```
+
+**Test Files:**
+
+- `tests/test_proxy_settings.py` - Tests for proxy settings configuration
+- `tests/test_verify_proxy.py` - Tests for proxy verification functionality
+
+### Manual Testing
+
+1. Run with `-vvv` for maximum verbosity (levels: -v, -vv, -vvv, -vvvv)
+2. Use `--dump` to generate debug data dumps
+3. Check log files in `./logs/` directory
+4. Use `--debug-ws` for websocket debug logging
+5. Use `--debug-gql` for GraphQL debug logging
+6. Monitor web GUI console output and browser developer tools
+
+## Web GUI Architecture
+
+The application uses a web-based interface accessible via browser:
+
+### Web GUI Components
+
+**src/web/gui_manager.py** - WebGUIManager class:
+
+- Managers: StatusManager, ConsoleOutputManager, ChannelListManager, CampaignProgressManager, InventoryManager, LoginFormManager, SettingsManager, CacheManager
+- Uses WebSocketBroadcaster to push real-time updates to connected clients via Socket.IO
+- Pure async/await implementation
+
+**src/web/app.py** - FastAPI application:
+
+- REST API endpoints: `/api/status`, `/api/channels`, `/api/campaigns`, `/api/console`, `/api/settings`, `/api/login`, `/api/oauth/confirm`, `/api/reload`, `/api/close`
+- Socket.IO events for real-time bi-directional communication
+- Serves static web frontend from `web/` directory
+- Integrates with WebGUIManager via `set_managers(gui, twitch)`
+
+**web/** - Frontend assets:
+
+- `index.html` - Single-page application layout with tabs
+- `static/app.js` - Socket.IO client, real-time UI updates, API calls, Inventory Filtering logic
+- `static/styles.css` - Responsive design with dark mode support
+
+### Communication Protocol
+
+**Server → Client (Socket.IO events):**
+
+- `initial_state` - Full state on connect
+- `status_update` - Status bar changes
+- `console_output` - New log lines
+- `channel_add/update/remove` - Channel list changes
+- `drop_progress` - Drop mining progress
+- `campaign_add` - New campaign added
+- `login_required` - Prompt for credentials
+- `settings_updated` - Settings changed
+
+**Client → Server:**
+
+- REST API for actions (login, settings, channel selection)
+- Socket.IO for connection management
+
+### Docker Integration
+
+**src/config/paths.py:**
+
+- Detects Docker environment via `DOCKER_ENV` env var or `/.dockerenv` file
+- Docker: Uses `/app` for code, `/app/data` for persistent storage
+- Development: Uses `<project_root>/data` for persistent storage
+- All user data (cookies, settings, cache, logs) stored in DATA_DIR
+- Provides `_resource_path()` helper for locating bundled resources
+
+**Dockerfile:**
+
+- Based on `python:3`
+- Installs dependencies from `pyproject.toml`
+- Exposes port 8080
+- Health check on `/api/status`
+
+**docker-compose.yml:**
+
+- Volume mounts `./data:/app/data` for persistence
+- Port mapping `8080:8080`
+- Auto-restart policy
+- Timezone configuration
+
+### Key Design Decisions
+
+- **WebSocket for real-time** - Socket.IO chosen for reliability (fallback to polling)
+- **Single-page app** - Simpler than full framework (React/Vue), fast load times
+- **Direct Docker support** - Environment detection, proper path handling
+- **OAuth device code flow** - Works great for web-based deployment
