- Encrypted per-user provider credentials storage

Admin Interface:
- Complete admin panel with Livewire components
- User management with CRUD operations
- API key management with testing capabilities
- Budget system with limits and reset schedules
- Usage logs with filtering and CSV export
- Model pricing management with cost calculator
- Dashboard with Chart.js visualizations

Database Schema:
- MariaDB migrations for all tables
- User provider credentials (encrypted)
- LLM request logging
- Budget tracking and rate limiting
- Model pricing configuration

API Implementation:
- OpenAI-compatible endpoints
- Budget checking middleware
- Rate limit enforcement
- Request logging jobs
- Cost calculation service

Testing:
- Unit tests for all provider services
- Provider factory tests

-## 📝 Nächste Schritte
+## 🔐 Sicherheit
 
-### 1. Models erstellen
+### Production Checklist
 
-Folge dem Implementierungskonzept in `LARAVEL_IMPLEMENTATION.md`:
+Vor dem Production-Einsatz:
 
+1. ✅ `.env` Konfiguration:
+   ```env
+   APP_ENV=production
+   APP_DEBUG=false
+   APP_KEY=... (sicher generieren!)
+   ```
+
+2. ✅ Admin-Passwort ändern
+
+3. ✅ MariaDB Root-Passwort ändern
+
+4. ✅ phpMyAdmin deaktivieren oder absichern
+
+5. ✅ SSL/TLS einrichten
+
+6. ✅ Laravel Caches aktivieren:
    ```bash
-docker compose exec laravel php artisan make:model GatewayUser
+   php artisan config:cache
-docker compose exec laravel php artisan make:model ApiKey
+   php artisan route:cache
-docker compose exec laravel php artisan make:model UsageLog
+   php artisan view:cache
-docker compose exec laravel php artisan make:model Budget
+   php artisan optimize
-docker compose exec laravel php artisan make:model ModelPricing
    ```
 
-### 2. Controllers implementieren
+### API-Key Verschlüsselung
 
-```bash
+Provider API-Keys werden verschlüsselt in der Datenbank gespeichert:
-docker compose exec laravel php artisan make:controller DashboardController
+- Verwendung von Laravel's Encryption
-docker compose exec laravel php artisan make:controller GatewayUserController --resource
+- Basiert auf APP_KEY
-```
+- Automatische Ver-/Entschlüsselung
 
-### 3. Views erstellen
+---
 
-Die Views werden in `laravel-app/resources/views/` erstellt.
+## 📊 Monitoring & Analytics
