-- **models/TrainingProjectDetails.py**
-- **models/training.py**
-- **models/LabelStudioProject.py**
-- **models/Images.py**
-- **models/Annotation.py**
-- **models/__init__.py**
-
-### API Routes
-- **routes/api.py** - All API endpoints converted to Flask blueprints (replaces api.js)
-- **routes/__init__.py**
-
-### Services
-- **services/fetch_labelstudio.py** - Label Studio API integration
-- **services/seed_label_studio.py** - Database seeding logic
-- **services/generate_json_yolox.py** - COCO JSON generation
-- **services/generate_yolox_exp.py** - YOLOX experiment file generation

-- **services/__init__.py**
-
-### Documentation
-- **README.md** - Comprehensive documentation
-- **QUICKSTART.md** - Quick setup guide
-- **.gitignore** - Python-specific ignore patterns
-
-## 🔄 Key Changes
-
-### Technology Stack
-| Component | Node.js | Python |
-|-----------|---------|--------|
-| Framework | Express.js | Flask |
-| ORM | Sequelize | SQLAlchemy |
-| HTTP Client | node-fetch | requests |
-| Package Manager | npm | pip |
-| Runtime | Node.js | Python 3.8+ |
-
-### API Compatibility
-✅ All endpoints preserved with same URLs
-✅ Request/response formats maintained
-✅ Same database schema
-✅ Same business logic
-
-### Converted Features
-- ✅ Training project management
-- ✅ Label Studio integration
-- ✅ YOLOX configuration and training
-- ✅ File upload handling
-- ✅ Image and annotation management
-- ✅ COCO JSON generation
-- ✅ Training logs
-
-## 🚀 Getting Started
-
-1. **Install dependencies:**
-   ```bash
-   cd backend
-   python -m venv venv
-   .\venv\Scripts\Activate.ps1  # Windows
-   pip install -r requirements.txt
-   ```
-
-2. **Run the server:**
-   ```bash
-   python start.py
-   ```
-
-3. **Server runs at:** `http://0.0.0.0:3000`
-
-## 📦 Dependencies Installed
-
-- Flask 3.0.0 - Web framework
-- Flask-CORS 4.0.0 - Cross-origin resource sharing
-- Flask-SQLAlchemy 3.1.1 - ORM integration
-- SQLAlchemy 2.0.23 - Database ORM
-- PyMySQL 1.1.0 - MySQL driver
-- requests 2.31.0 - HTTP client
-- Pillow 10.1.0 - Image processing
-
-## ⚠️ Important Notes
-
-1. **Virtual Environment**: Always activate the virtual environment before running
-2. **Database**: MySQL must be running with the `myapp` database created
-3. **Credentials**: Update database credentials in `app.py` if needed
-4. **Python Version**: Requires Python 3.8 or higher
-
-## 🧪 Testing
-
-Test the conversion:
-```bash
-# Get all training projects
-curl http://localhost:3000/api/training-projects
-
-# Get Label Studio projects
-curl http://localhost:3000/api/label-studio-projects
-```
-
-## 📝 Original Files
-
-Your original Node.js files remain untouched:
-- server.js
-- package.json
-- routes/api.js
-- models/*.js (JavaScript)
-- services/*.js (JavaScript)
-
-You can keep them as backup or remove them once you verify the Python version works correctly.
-
-## 🔍 What to Verify
-
-1. ✅ Database connection works
-2. ✅ All API endpoints respond correctly
-3. ✅ File uploads work
-4. ✅ Label Studio integration works
-5. ✅ YOLOX training can be triggered
-6. ✅ COCO JSON generation works
-
-## 🐛 Troubleshooting

+## 1. Einleitung
+
+### 1.1 Das Unternehmen
+
+[HIER INHALT VON KOLLEGE ÜBERNEHMEN - Firmenbeschreibung, Standort, Mitarbeiter, Branche, etc.]
+
+### 1.2 Projektumfeld
+
+[HIER INHALT VON KOLLEGE ÜBERNEHMEN - Übergeordnetes Projekt, Teamstruktur, Projektorganisation, etc.]
+
+### 1.3 Projektziel
+
+Der **mb ai Trainer** ist eine webbasierte Anwendung zur vollständigen Verwaltung und Durchführung von YOLOX-Modelltrainings im Bereich Computer Vision. Das System wurde entwickelt, um den gesamten Machine Learning Workflow - von der Datenannotation über das Training bis zur Modell-Evaluierung - in einer einheitlichen Plattform zu integrieren.
+
+**Hauptziele des Projekts:**
+
+- Entwicklung einer benutzerfreundlichen Weboberfläche zur Verwaltung von Trainingsprojekten
+- Integration von Label Studio für professionelle Bildannotation
+- Implementierung einer robusten Datenverwaltung mit MySQL
+- Automatisierung des YOLOX-Trainingsprozesses
+- Bereitstellung eines Transfer Learning Systems mit vordefinierten Basis-Konfigurationen
+- Zentrale Verwaltung aller Trainingsparameter und -verläufe
+
+### 1.4 Projektbegründung
+
+Im Bereich des Machine Learning für Computer Vision existieren zahlreiche isolierte Tools für verschiedene Aufgaben (Annotation, Training, Evaluierung). Dies führt zu:
+
+- **Hohem Verwaltungsaufwand:** Daten müssen zwischen verschiedenen Tools transferiert werden
+- **Fehlerpotential:** Manuelle Konfiguration von Trainingsskripten ist fehleranfällig
+- **Keine Nachvollziehbarkeit:** Trainingsverläufe und verwendete Parameter sind nicht zentral dokumentiert
+- **Steile Lernkurve:** Neue Teammitglieder müssen mehrere Tools erlernen
+
+Der mb ai Trainer löst diese Probleme durch eine integrierte Plattform, die alle notwendigen Funktionen vereint.

+
+### 3.2 Systemarchitektur
+
+#### 3.2.1 Backend-Architektur
+
+Das Backend des mb ai Trainer ist als modulare Python/Flask-Anwendung aufgebaut:
+
+```

+└── routes/
+    └── api.py              # REST API Endpoints
+```
+
+**Datenfluss:**
+
+1. **Projektanlage:** Frontend → POST `/api/training-projects` → MySQL
+2. **Label Studio Sync:** Backend → Label Studio API → MySQL (Images, Annotations)
+3. **Transfer Learning:**
+   - Frontend wählt "Train on coco" + Model
+   - GET `/api/base-config/<model_name>` → Basis-Config laden
+   - Frontend sperrt geschützte Felder
+4. **Training Start:**
+   - POST `/api/yolox-settings` → Settings speichern
+   - POST `/api/start-yolox-training` → Exp.py generieren
+   - YOLOX Training starten
+
+#### 3.2.2 Basis-Konfiguration Format
+
+```python
+class BaseExp:
+    """Base configuration for YOLOX-S with COCO pretrained weights"""
+    # Model architecture parameters (protected)
+    depth = 0.33
+    width = 0.50
+    
+    # Training parameters (protected)
+    scheduler = "yoloxwarmcos"
+    activation = "silu"
+    # ... weitere Parameter
+```
+
+#### 3.2.3 API Design
+
+**Endpoint:** `GET /api/base-config/<model_name>`
+
+**Response:**
+```json
+{
+  "depth": 0.33,
+  "width": 0.50,
+  "activation": "silu",
+  "scheduler": "yoloxwarmcos",
+  // ... weitere Parameter
+}
+```
+
+### 3.3 Implementierung
+
+#### 3.3.1 Backend: Dynamic Module Loading
+
+Die Basis-Konfigurationen werden zur Laufzeit dynamisch geladen:
+
+```python
+import importlib.util
+import os
+
+def load_base_config(selected_model):
+    """Dynamically load base configuration for selected model"""
+    model_map = {
+        'yolox-s': 'yolox_s.py',
+        'yolox-m': 'yolox_m.py',
+        'yolox-l': 'yolox_l.py',
+        'yolox-x': 'yolox_x.py'
+    }
+    
+    file_name = model_map.get(selected_model.lower())
+    if not file_name:
+        return None
+    
+    base_dir = os.path.join(os.path.dirname(__file__), '..', 'data')
+    file_path = os.path.join(base_dir, file_name)
+    
+    # Dynamic import
+    spec = importlib.util.spec_from_file_location("base_exp", file_path)
+    module = importlib.util.module_from_spec(spec)
+    spec.loader.exec_module(module)
+    
+    return module.BaseExp
+```
+
+**Vorteile:**
+- Keine hardcodierten Imports
+- Neue Modelle können ohne Code-Änderung hinzugefügt werden
+- Klare Trennung von Konfiguration und Logik
+
+#### 3.3.2 Backend: Configuration Merging
+
+Die Merge-Strategie kombiniert drei Quellen:
+
+```python
+def generate_yolox_inference_exp(training_id, options, use_base_config=True):
+    """Generate exp.py with base config support"""
+    
+    # 1. Load base configuration
+    base_config = load_base_config(selected_model) if use_base_config else None
+    
+    # 2. Load user-defined values from database
+    training = db.session.get(Training, training_id)
+    
+    # 3. Merge with priority: base > user > defaults
+    final_config = {}
+    
+    # Protected parameters from base config
+    protected_params = ['depth', 'width', 'activation', 'scheduler', ...]
+    
+    for param in protected_params:
+        if base_config and hasattr(base_config, param):
+            final_config[param] = getattr(base_config, param)
+        elif hasattr(training, param):
+            final_config[param] = getattr(training, param)
+        else:
+            final_config[param] = DEFAULT_VALUES.get(param)
+    
+    return final_config
+```
+
+**Priorität:**
+1. **Base Config** (höchste Priorität bei COCO-Mode)
+2. **User Values** (für nicht-geschützte Parameter)
+3. **Default Values** (Fallback)
+
+#### 3.3.3 Frontend: Field Locking
+
+Das Frontend zeigt geschützte Felder visuell an:
+
+```javascript
+const protectedFields = [
+    'depth', 'width', 'activation', 'scheduler', 'nmsthre', 
+    'momentum', 'weight_decay', 'warmup_epochs', 'max_epoch',
+    // ... weitere Felder
+];
+
+function applyBaseConfig(config, isCocoMode) {
+    protectedFields.forEach(field => {
+        const input = document.querySelector(`[name="${field}"]`);
+        
+        if (input && config.hasOwnProperty(field)) {
+            // Set value
+            input.value = config[field];
+            
+            if (isCocoMode) {
+                // Lock field
+                input.disabled = true;
+                input.style.backgroundColor = '#d3d3d3';
+                input.style.cursor = 'not-allowed';
+                input.title = 'This parameter is locked by base configuration';
+            }
+        }
+    });
+    
+    // Show/hide info banner
+    const banner = document.getElementById('base-config-info');
+    banner.style.display = isCocoMode ? 'block' : 'none';
+}
+```
+
+**UI-Features:**
+- Grauer Hintergrund für gesperrte Felder
+- Cursor: `not-allowed` für visuelle Rückmeldung
+- Tooltip erklärt warum Feld gesperrt ist
+- Grüner Info-Banner zeigt aktive Basis-Konfiguration
+
+#### 3.3.4 Frontend: Field Name Mapping
+
+Alias-Handling für Backend/Frontend Unterschiede:
+
+```javascript
+const fieldNameMap = {
+    'activation': 'act',        // Backend: activation, Frontend: act
+    'nms_thre': 'nmsthre'       // Backend: nms_thre, Frontend: nmsthre
+};
+
+function applyBaseConfig(config, isCocoMode) {
+    for (const [backendName, value] of Object.entries(config)) {
+        // Try direct match first
+        let input = document.querySelector(`[name="${backendName}"]`);
+        
+        // Try mapped name if direct match fails
+        if (!input && fieldNameMap[backendName]) {
+            const frontendName = fieldNameMap[backendName];
+            input = document.querySelector(`[name="${frontendName}"]`);
+        }
+        
+        if (input) {
+            input.value = value;
+            // ... weitere Logik
+        }
+    }
+}
+```
+
+### 3.4 Testing und Validierung
+
+#### 3.4.1 Unit Tests
+
+Erstellte Test-Suite für Basis-Konfigurationen:
+
+```python
+# backend/data/test_base_configs.py
+import importlib.util
+import os
+
+def test_base_config(file_name, expected_depth, expected_width):
+    """Test if base config loads correctly"""
+    file_path = os.path.join(os.path.dirname(__file__), file_name)
+    
+    spec = importlib.util.spec_from_file_location("base_exp", file_path)
+    module = importlib.util.module_from_spec(spec)
+    spec.loader.exec_module(module)
+    
+    config = module.BaseExp
+    assert config.depth == expected_depth
+    assert config.width == expected_width
+    # ... weitere Assertions
+
+# Run tests
+test_base_config('yolox_s.py', 0.33, 0.50)
