# Implementation Summary

## Overview
This implementation addresses the two requirements from the problem statement:
1. ✅ Clean actions artifacts once files are added to the repository
2. ✅ Add push notifications to the app

## What Was Done

### 1. Artifact Cleanup (Models no longer in Git)

**Problem**: Large ML model files (100MB+) were committed to git, bloating the repository.

**Solution**:
- Removed all model files (.h5, .tflite) and token files (.tokens) from git tracking
- Added comprehensive `.gitignore` to prevent future commits
- Created GitHub Actions workflows to build models and store as artifacts
- Implemented automatic cleanup of old artifacts (keeps only latest)

**Files Removed from Git**:
- 8 model files (.h5 and .tflite) totaling ~100MB
- 4 token files totaling ~3MB
- Additional production model copies

**New Workflows**:
1. `build-models.yml`: Builds models on dataset/script changes
2. `clean-artifacts.yml`: Daily cleanup of old artifacts

### 2. Push Notifications

**Problem**: No push notifications were sent when malicious requests were detected.

**Solution**:
- Implemented Firebase Cloud Messaging (FCM) integration
- Added `notification_service.py` with async HTTP support using aiohttp
- Integrated into both Dev and Prod server main loops
- Sends notifications when malicious requests are detected (URI or Body)

**Features**:
- ✅ Real-time alerts for malicious requests
- ✅ Configurable via environment variables (FCM_SERVER_KEY)
- ✅ Support for multiple device tokens
- ✅ Detailed notification payload with timestamp, client IP, and verdict
- ✅ Graceful degradation when notifications are disabled

**Notification Format**:
```json
{
"title": "🚨 Malicious Request Detected",
"body": "Source: [IP]\nTime: [timestamp]\nType: [URI/Body]",
"data": {
"timestamp": "...",
"client": "...",
"uri": "...",
"verdict_uri": "MALICIOUS",
"verdict_body": "SAFE",
"type": "malicious_request"
}
}
```

## Files Modified

### Core Changes
- `server_socket_main.py` (Dev) - Added notification service integration
- `server_socket_main.py` (Prod) - Added notification service integration
- `.gitignore` (root) - Exclude models, tokens, secrets
- `Moulinette_Dev/.gitignore` - Enhanced with model exclusions
- `requirements.txt` - Added aiohttp dependency

### New Files
- `.github/workflows/build-models.yml` - Model building workflow
- `.github/workflows/clean-artifacts.yml` - Artifact cleanup workflow
- `notification_service.py` (Dev & Prod) - Push notification service
- `device_tokens.json.example` - Device token template
- `.env.example` - Environment configuration template
- `SETUP_GUIDE.md` - Comprehensive setup instructions
- `QUICK_REFERENCE.md` - Quick reference for common tasks
- `test_notification_service.py` - Unit tests

### Updated Documentation
- `README.md` - Added features list and quick start

## Testing

All changes have been validated:
- ✅ Python syntax validated for all modified files
- ✅ YAML syntax validated for all workflows
- ✅ Unit tests created and passing for notification service
- ✅ Model files successfully removed from git tracking
- ✅ Model files still present locally for runtime use

## Usage

### Setting Up Push Notifications
1. Get Firebase Server Key from Firebase Console
2. Set environment variable: `export FCM_SERVER_KEY="your_key"`
3. Copy `device_tokens.json.example` to `device_tokens.json`
4. Add your FCM device tokens to the JSON file
5. Start the server - notifications will be sent automatically

### Managing ML Models
- **Build locally**: Run scripts in `Moulinette_Dev/Scripts/Build/`
- **Build via Actions**: Trigger "Build ML Models" workflow
- **Download**: Get artifacts from GitHub Actions

## Architecture

```
Request → WAF Proxy → Main Server → ML Hearts (XSS, SQL, Path Traversal)
Notification Service → Firebase FCM → Mobile Apps
```

## Security Notes
- ⚠️ Never commit `device_tokens.json` or `.env` files
- ⚠️ FCM server key should be kept secret
- ⚠️ All sensitive files are now in `.gitignore`

## Impact
- **Repository size**: Reduced by ~100MB
- **Developer experience**: Models built via CI/CD
- **Security monitoring**: Real-time push notifications
- **Maintainability**: Clear documentation and examples

## Next Steps for Users
1. Set up Firebase project and get FCM server key
2. Configure device tokens for target devices
3. Set up mobile app to receive FCM notifications
4. Run the workflows to verify artifact management works
5. Test notifications by sending malicious requests
