Complete Phase 7: Polish & Cross-Cutting Concerns

This commit implements all remaining polish tasks (T193-T210) to make
the application production-ready.

## Logging & Monitoring (T193, T194, T208, T209)
- Add structured JSON logging for production environments
- Add human-readable logging for development
- Implement comprehensive error logging across all routes:
  * submission.py: product access, validation, success/failure
  * auth.py: login attempts, successes, failures, logouts
  * dashboard.py: access and errors
- Add /health endpoint for monitoring (checks data dir, API key)
- Add environment variable validation on startup

## Security Hardening (T196-T199, T207)
- Add HSTS headers in production (1 year, includeSubDomains)
- Add security headers: X-Content-Type-Options, X-Frame-Options, X-XSS-Protection
- Verify CSRF protection on all POST routes (Flask-WTF)
- Verify session cookie security flags (HttpOnly, Secure, SameSite)
- Verify XSS prevention (Jinja2 auto-escaping)
- Verify no hardcoded secrets (only in test files)

## Documentation (T195, T203, T210)
- Add comprehensive README.md with:
  * Features, quick start, project structure
  * Usage guides (end users, product owners, admins)
  * Configuration, testing, deployment instructions
- Add detailed docs/deployment.md with:
  * Production deployment steps
  * ClamAV, Nginx, SSL/TLS setup
  * Security hardening, monitoring, backup strategies
- Add requirements-dev.txt for development dependencies

## Performance Testing (T200, T201)
- Add test_performance.py with 4 comprehensive tests:
  * 100 concurrent submissions (SC-012)
  * Dashboard load <3s for 1000 items (SC-008)
  * Large file upload handling
  * Rate limiting verification
- Add performance marker to pytest.ini

## Testing
- All 49 tests passing, 1 skipped
- Fixed error handling to preserve HTTP status codes

Phase 7 complete. Application is production-ready with comprehensive
logging, security, monitoring, and documentation.

+
+## Usage
+
+### For End Users (Anonymous Feedback)
+
+1. Navigate to `/submit/{product-slug}`
+2. Enter your feedback in any language (optional if attaching files)
+3. Optionally attach up to 3 files (max 10MB each)
+4. Submit - your feedback is completely anonymous
+
+### For Product Owners (Dashboard)
+
+1. Navigate to `/login`
+2. Log in with your credentials
+3. View feedback list at `/dashboard`
+4. Filter by category, status, language, or search keywords
+5. Click on feedback to view details and AI analysis
+6. Update status or manually trigger analysis
+
+### For Administrators
+
+Administrators have access to all products. User and product management is currently done via YAML files (see POC note below).
+
+## Configuration
+
+### Environment Variables
+
+- `SECRET_KEY` - Flask secret key (required in production)
+- `ANTHROPIC_API_KEY` - Claude API key for AI analysis
+- `DATA_DIR` - Data storage directory (default: `./data`)
+- `MAX_CONTENT_LENGTH` - Max upload size in bytes (default: 10MB)
+- `CLAMD_SOCKET` - ClamAV socket path (default: `/var/run/clamav/clamd.ctl`)
+- `RATE_LIMIT_ENABLED` - Enable rate limiting (default: `true`)
+- `RATE_LIMIT_PER_HOUR` - Submissions per hour per IP (default: `10`)
+
+### Managing Products and Users (POC)
+
+**Note**: User Story 4 (Product/Service Registration and Management) has been deferred for the proof-of-concept. Products and users are managed manually via YAML files.
+
+#### Adding a Product
+
+1. Create directory: `data/products/{product-id}/`
+2. Create `config.yaml`:
+```yaml
+product_id: my-product
+name: My Product
+submission_url_slug: my-product-feedback
+owner_language: en
+assigned_owner_ids:
+  - owner1
+status: active
+```
+
+#### Adding a User
+
+Edit `data/users.yaml`:
+```yaml
+- user_id: user1
+  username: productowner
+  password_hash: $2b$12$...  # Generate with bcrypt
+  role: product_owner
+  is_active: true
+  product_ids:
+    - my-product
+```
+
+To generate a password hash:
+```python
+import bcrypt
+print(bcrypt.hashpw(b'password', bcrypt.gensalt()).decode())
+```
+
+## Testing
+
+Run the test suite:
+```bash
+# All tests
+pytest
+
+# Contract tests only
+pytest tests/contract/
+
+# Integration tests only
+pytest tests/integration/
+
+# With coverage
+pytest --cov=app --cov-report=html
+```
+
+## Development
+
+Install development dependencies:
+```bash
+pip install -r requirements-dev.txt
+```
+
+Run code quality checks:
+```bash
+# Linting
+ruff check .
+
+# Formatting
+black .
+
+# Type checking
+mypy app/
+```
+
+## Production Deployment
+
+See [Deployment Guide](docs/deployment.md) for detailed instructions on:
+- ClamAV setup
+- Nginx reverse proxy configuration
+- HTTPS/TLS setup
+- Systemd service configuration
+- Security hardening
+
+## Security Features
+
+- ✅ CSRF protection on all POST routes (Flask-WTF)
+- ✅ Session cookie security flags (HttpOnly, Secure in production, SameSite)
+- ✅ HSTS headers in production (1 year, includeSubDomains)
+- ✅ Rate limiting on submissions (configurable, default 10/hour)
+- ✅ File upload validation (type, size, virus scanning)
+- ✅ Complete anonymity (no IP logging for submissions)
+- ✅ Structured logging (JSON format in production)
+- ✅ Environment variable validation on startup
+- ✅ Health check endpoint (`/health`)
+
+## API Endpoints
+
+### Public (No Authentication)
+- `GET /submit/{product_slug}` - Display submission form
+- `POST /submit/{product_slug}` - Submit feedback
+- `GET /health` - Health check endpoint
+
+### Authenticated (Product Owners)
+- `GET /login` - Login page
+- `POST /login` - Process login
+- `GET /logout` - Logout
+- `GET /dashboard` - Feedback list with filters
+- `GET /feedback/{id}` - Feedback detail
+- `POST /feedback/{id}/status` - Update feedback status
+- `POST /feedback/{id}/analyze` - Manually trigger AI analysis
+- `GET /feedback/{id}/attachment/{filename}` - Download attachment
+
+## Technology Stack
+
+- **Backend**: Python 3.11+ with Flask 3.0
+- **AI**: Anthropic Claude API
+- **Security**: ClamAV, Flask-WTF (CSRF), Flask-Limiter (rate limiting)
+- **Authentication**: Flask-Login with bcrypt password hashing
+- **Storage**: File-based (YAML + Markdown, no database)
+- **Testing**: pytest with contract and integration tests
+- **Frontend**: Plain HTML with minimal inline CSS (no frameworks)

+
+# Update virus definitions
+sudo freshclam
+
+# Start and enable ClamAV daemon
+sudo systemctl start clamav-daemon
+sudo systemctl enable clamav-daemon
+
+# Verify ClamAV is running
+sudo systemctl status clamav-daemon
+
+# Test ClamAV socket
+clamdscan --version
+```
+
+**ClamAV Configuration File** (`/etc/clamav/clamd.conf`):
+```conf
+# Uncomment this line if present
+LocalSocket /var/run/clamav/clamd.ctl
+
+# Set appropriate permissions

+
+# Memory limits
+MaxFileSize 25M
+MaxScanSize 100M
+```
+
+### 3. Application Deployment
+
+```bash
+# Create application user
+sudo useradd -r -s /bin/bash -m -d /opt/reklamator reklamator
+
+# Switch to application user
+sudo su - reklamator
+
+# Clone repository
+git clone <repository-url> /opt/reklamator/app
+cd /opt/reklamator/app
+
+# Create virtual environment
+python3.11 -m venv venv
+source venv/bin/activate
+
+# Install dependencies
+pip install --upgrade pip
+pip install -r requirements.txt
+
+# Create data directory
+mkdir -p /opt/reklamator/data
+
+# Exit back to root
+exit
+```
+
+### 4. Environment Configuration
+
+Create `/opt/reklamator/app/.env`:
+
+```bash
+# Security (REQUIRED)
+SECRET_KEY=<generate-secure-key>
+ANTHROPIC_API_KEY=<your-api-key>
+
+# Paths
+DATA_DIR=/opt/reklamator/data
+

+
+# Rate Limiting
+RATE_LIMIT_ENABLED=true
+RATE_LIMIT_PER_HOUR=10
+
+# File Upload
+MAX_CONTENT_LENGTH=10485760
+```
+
+**Generate SECRET_KEY:**
+```bash
+python3 -c "import secrets; print(secrets.token_hex(32))"
+```
+
+Set proper permissions:
+```bash
+sudo chown reklamator:reklamator /opt/reklamator/app/.env
+sudo chmod 600 /opt/reklamator/app/.env
+```
+
+### 5. Initialize Application
+
+```bash
+# Switch to application user
+sudo su - reklamator
+cd /opt/reklamator/app
+source venv/bin/activate
+
+# Initialize admin user
+python init_admin.py
+# Follow prompts to create admin user

+# Create test product (optional)
+mkdir -p /opt/reklamator/data/products/test-product
+cat > /opt/reklamator/data/products/test-product/config.yaml <<EOF
+product_id: test-product
+name: Test Product
+submission_url_slug: test-feedback
+owner_language: en
+assigned_owner_ids:
+  - admin
+status: active
+EOF
+
+exit
+```
+
+### 6. Systemd Service Configuration
+
+Create `/etc/systemd/system/reklamator.service`:
+
+```ini
+[Unit]
+Description=Reklamator Feedback Platform
+After=network.target clamav-daemon.service
+Requires=clamav-daemon.service
+
+[Service]
+Type=simple
+User=reklamator
+Group=reklamator
+WorkingDirectory=/opt/reklamator/app
+Environment="PATH=/opt/reklamator/app/venv/bin"
+Environment="FLASK_ENV=production"
+ExecStart=/opt/reklamator/app/venv/bin/python run.py
+
+# Security hardening
+NoNewPrivileges=true
+PrivateTmp=true
+ProtectSystem=strict
+ProtectHome=true
+ReadWritePaths=/opt/reklamator/data
+RestartSec=10
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable and start the service:
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable reklamator
+sudo systemctl start reklamator
+sudo systemctl status reklamator
+```
+
+### 7. Nginx Reverse Proxy Configuration
+
+Create `/etc/nginx/sites-available/reklamator`:
+
+```nginx
+# Redirect HTTP to HTTPS
+server {
+    listen 80;
+    listen [::]:80;
+    server_name feedback.yourdomain.com;
+
+    location /.well-known/acme-challenge/ {
+        root /var/www/html;
+    }
+
+    location / {
+        return 301 https://$server_name$request_uri;
+    }
+}
+
+# HTTPS server
+server {
+    listen 443 ssl http2;
+    listen [::]:443 ssl http2;
+    server_name feedback.yourdomain.com;
+
+    # SSL Configuration
+    ssl_certificate /etc/letsencrypt/live/feedback.yourdomain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/feedback.yourdomain.com/privkey.pem;
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_ciphers HIGH:!aNULL:!MD5;
+    ssl_prefer_server_ciphers on;
+    ssl_session_cache shared:SSL:10m;
+    ssl_session_timeout 10m;
+
+    # Security Headers (additional to Flask's HSTS)
+    add_header X-Content-Type-Options "nosniff" always;
+    add_header X-Frame-Options "DENY" always;
+    add_header X-XSS-Protection "1; mode=block" always;
+    add_header Referrer-Policy "strict-origin-when-cross-origin" always;
+
+    # Max upload size (must match Flask's MAX_CONTENT_LENGTH)
+    client_max_body_size 35M;  # 3 files × 10MB + overhead
+
+    # Timeouts
+    proxy_connect_timeout 60s;
+    proxy_send_timeout 60s;
+    proxy_read_timeout 60s;
+
+    # Logging
+    access_log /var/log/nginx/reklamator_access.log;
+    error_log /var/log/nginx/reklamator_error.log;
+
+    # Proxy to Flask app
+    location / {
+        proxy_pass http://127.0.0.1:5000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+
+        # Don't buffer large uploads
+        proxy_request_buffering off;
+    }
+
+    # Health check endpoint (no authentication)
+    location /health {
+        proxy_pass http://127.0.0.1:5000/health;
+        access_log off;
+    }
+}
+```
+
+Enable the site:
+```bash
+sudo ln -s /etc/nginx/sites-available/reklamator /etc/nginx/sites-enabled/
+sudo nginx -t
+sudo systemctl reload nginx
+```
+
+### 8. SSL/TLS Certificate (Let's Encrypt)
+
+```bash
+# Obtain certificate
+sudo certbot --nginx -d feedback.yourdomain.com
+
+# Test auto-renewal
+sudo certbot renew --dry-run
+```
+
+Certbot will automatically update the Nginx configuration with SSL settings.
+
+### 9. Firewall Configuration
+
+```bash
+# Allow SSH, HTTP, and HTTPS
+sudo ufw allow OpenSSH
+sudo ufw allow 'Nginx Full'
+sudo ufw enable
+sudo ufw status
+```
+
+## Post-Deployment Verification
+
+### Health Check
+
+```bash
+curl https://feedback.yourdomain.com/health
+```
+
+Expected response:
+```json
+{
+  "status": "healthy",
+  "timestamp": "2024-01-15T12:00:00Z",
+  "environment": "production"
+}
+```
+
+### Test Submission
+
+1. Visit `https://feedback.yourdomain.com/submit/test-feedback`
+2. Submit test feedback
+3. Check logs: `sudo journalctl -u reklamator -f`
+4. Verify file creation: `ls -la /opt/reklamator/data/products/test-product/feedback/`
+
+### Test Dashboard
+
+1. Visit `https://feedback.yourdomain.com/login`
+2. Log in with admin credentials
+3. Verify dashboard loads: `https://feedback.yourdomain.com/dashboard`
+
+## Monitoring and Logging
+
+### Application Logs
+
+```bash
+# Real-time logs
+sudo journalctl -u reklamator -f
+
+# Last 100 lines
+sudo journalctl -u reklamator -n 100
+
+# Logs with timestamps
+sudo journalctl -u reklamator --since "1 hour ago"
+```
+
+### Nginx Logs
+
+```bash
+# Access logs
+sudo tail -f /var/log/nginx/reklamator_access.log
+
+# Error logs
+sudo tail -f /var/log/nginx/reklamator_error.log
+```
+
+### Health Monitoring
+
+Set up automated health checks with your monitoring service:
+
+```bash
+# Example with curl in cron
+*/5 * * * * curl -f https://feedback.yourdomain.com/health || echo "Reklamator health check failed" | mail -s "Alert: Reklamator Down" admin@yourdomain.com
+```
+
+### Log Rotation
+
+Create `/etc/logrotate.d/reklamator`:
+
+```
+/opt/reklamator/app/*.log {
+    daily
+    missingok
+    rotate 14
+    compress
+    delaycompress
+    notifempty
+    create 0640 reklamator reklamator
+    sharedscripts
+}
+```
+
+## Backup Strategy
+
+### Database Backup (YAML Files)
+
+```bash
+#!/bin/bash
+# /opt/reklamator/backup.sh
+
+BACKUP_DIR="/opt/reklamator/backups"
+DATA_DIR="/opt/reklamator/data"
+DATE=$(date +%Y%m%d_%H%M%S)
+
+mkdir -p $BACKUP_DIR
+
+# Backup data directory
+tar -czf $BACKUP_DIR/reklamator_data_$DATE.tar.gz -C $DATA_DIR .
+
+# Keep only last 7 days
+find $BACKUP_DIR -name "reklamator_data_*.tar.gz" -mtime +7 -delete
+
+echo "Backup completed: $BACKUP_DIR/reklamator_data_$DATE.tar.gz"
+```
+
+Make executable and add to cron:
+```bash
+chmod +x /opt/reklamator/backup.sh
+sudo crontab -e -u reklamator
+# Add: 0 2 * * * /opt/reklamator/backup.sh
+```
+
+## Maintenance
+
+### Update Application
+
+```bash
+sudo su - reklamator
+cd /opt/reklamator/app
+
+# Pull latest code
+git pull
+
+# Activate virtual environment
+source venv/bin/activate
+
+# Update dependencies
+pip install -r requirements.txt --upgrade
+
+# Exit back to root
+exit
+
+# Restart service
+sudo systemctl restart reklamator
+sudo systemctl status reklamator
+```
+
+### Update ClamAV Virus Definitions
+
+```bash
+# Manual update
+sudo freshclam
+
+# Automatic updates are configured by default in /etc/clamav/freshclam.conf
+```
+
+### Disk Space Management
+
+Monitor feedback storage:
+```bash
+du -sh /opt/reklamator/data/products/*/feedback
+```
+
+Archive old feedback:
+```bash
+# Example: Move feedback older than 1 year to archive
+find /opt/reklamator/data/products/*/feedback/ -type d -mtime +365 \
+  -exec mv {} /opt/reklamator/archive/ \;
+```
+
+## Security Hardening
+
+### File Permissions
+
+```bash
+# Application files
+sudo chown -R reklamator:reklamator /opt/reklamator/app
+sudo chmod -R 755 /opt/reklamator/app
+sudo chmod 600 /opt/reklamator/app/.env
+
+# Data directory
+sudo chown -R reklamator:reklamator /opt/reklamator/data
+sudo chmod -R 750 /opt/reklamator/data
+```
+
+### ClamAV Permissions
+
+Add reklamator user to clamav group:
+```bash
+sudo usermod -a -G clamav reklamator
+```
+
+### Rate Limiting
+
+Nginx can provide additional rate limiting:
+
+```nginx
+# Add to http block in /etc/nginx/nginx.conf
+limit_req_zone $binary_remote_addr zone=submission:10m rate=10r/h;
+
+# Add to location block for /submit/*
+location ~ ^/submit/ {
+    limit_req zone=submission burst=2 nodelay;
+    proxy_pass http://127.0.0.1:5000;
+    # ... other proxy settings
+}
+```
+
+### Intrusion Detection
+
+Install and configure fail2ban:
+```bash
+sudo apt install fail2ban
+
+# Create /etc/fail2ban/jail.local
+[nginx-limit-req]
+enabled = true
+filter = nginx-limit-req
+logpath = /var/log/nginx/reklamator_error.log
+maxretry = 5
+bantime = 3600
+```
+
+## Troubleshooting
+
+### Service Won't Start
+
+```bash
+# Check service status
+sudo systemctl status reklamator
+
+# Check logs
+sudo journalctl -u reklamator -n 50 --no-pager
+
+# Common issues:
+# - Missing environment variables
+# - ClamAV not running
+# - Permissions on data directory
+# - Port 5000 already in use
+```
+
+### ClamAV Connection Errors
+
+```bash
+# Check ClamAV daemon status
+sudo systemctl status clamav-daemon
+
+# Test socket connection
+clamdscan --version
+
+# Check permissions
+ls -la /var/run/clamav/clamd.ctl
+
+# Restart ClamAV
+sudo systemctl restart clamav-daemon
+```
+
+### High Memory Usage
+
+```bash
+# Check memory usage
+free -h
+
+# Restart application to clear memory leaks
+sudo systemctl restart reklamator
+
+# Consider increasing server resources if processing large volumes
+```
+
+### Slow AI Analysis
+
+```bash
+# Check Anthropic API rate limits in logs
+sudo journalctl -u reklamator | grep "analysis"
+
+# Consider increasing timeout in config/production.py
+# ANTHROPIC_API_TIMEOUT = 60  # seconds
+```
+
+## Performance Tuning
+
+### Gunicorn Configuration (Optional)
+
+For production deployments with high traffic, use Gunicorn instead of Flask's development server.
+
+Install Gunicorn:
+```bash
+sudo su - reklamator
+source /opt/reklamator/app/venv/bin/activate
+pip install gunicorn
+```
+
+Update systemd service (`/etc/systemd/system/reklamator.service`):
+```ini
+[Service]
+ExecStart=/opt/reklamator/app/venv/bin/gunicorn -w 4 -b 127.0.0.1:5000 --timeout 60 'run:app'
+```
+
+Restart:
+```bash
+sudo systemctl daemon-reload
+sudo systemctl restart reklamator
+```
+
+### Nginx Caching (Optional)
+
+For static assets:
+```nginx
+location /static/ {
+    alias /opt/reklamator/app/static/;
+    expires 1y;
+    add_header Cache-Control "public, immutable";
+}
+```
+
+## Support
+
+For issues during deployment:
+1. Check application logs: `sudo journalctl -u reklamator -f`
+2. Check Nginx logs: `sudo tail -f /var/log/nginx/reklamator_error.log`
+3. Verify health endpoint: `curl https://feedback.yourdomain.com/health`
+4. Review configuration files for typos
+5. Ensure all environment variables are set in `.env`
+
+For additional help, consult the main README.md or open an issue on GitHub.
