# 🏗️ **API-Driven Judge Scoring Architecture**

## **Overview**
This new architecture separates the scoring panel into clean, maintainable layers:

### **🎯 Key Benefits:**

1. **✅ API-First Design**
   - All database operations moved to dedicated API endpoints
   - Clean separation of data layer from presentation layer
   - Standardized JSON responses

2. **📱 Dynamic Interface Generation**
   - Form structure generated via API calls
   - Responsive design that adapts to event configuration
   - Real-time data updates

3. **🔧 Better Maintainability**
   - Single source of truth for data operations
   - Modular, reusable API functions
   - Easier testing and debugging

4. **🚀 Enhanced User Experience**
   - Real-time debug monitoring
   - Smooth API call tracking
   - Better error handling

## **🏗️ Architecture Components**

### **1. API Layer (`api/judge_score_api.php`)**
```php
// Endpoints available:
- get_judge_context    → Judge info & assigned events
- get_event_data      → Event details, heats, criteria, figures
- get_participants    → Participants for specific heat/run
- get_scoring_form    → Form structure & validation rules
- submit_score        → Submit new score
- update_score        → Update existing score
- get_latest_scores   → Recent judge scores
- get_participant_scores → All scores for participant
- get_heat_flow       → Active heat information
```

### **2. Presentation Layer (`judge/score_panel.html`)**
```javascript
// Dynamic interface generation:
- Bootstrap 5.3.0 responsive design
- Lucide icons for modern UI
- Real-time form population via API
- Touch-friendly mobile interface
- Debug panel for development
```

### **3. Data Flow**
```
User Interface → API Calls → Database → JSON Response → UI Update
```

---

## **📊 Debug System**

The new panel includes comprehensive debugging:

### **📥 Incoming Data Monitor:**
```json
{
  "event_info": {
    "event_id": "3",
    "event_name": "Hocki Klocki", 
    "event_date": "2025-07-28"
  },
  "judge_info": {
    "judge_id": "1",
    "judge_name": "admin",
    "user_type": "admin"
  },
  "participant_info": {
    "selected_participant": "1508",
    "heat_number": "1", 
    "run_number": "1"
  },
  "form_data": {
    "score_value": "85.5",
    "status": "scored",
    "figures_json": "{\"Rotation\":[\"720\",\"900\"]}"
  }
}
```

### **📤 API Call Tracking:**
- Real-time monitoring of all API requests
- Response time measurement
- Error logging and status tracking
- Request/response data inspection

---

## **🔄 Migration Benefits**

### **Before (Mixed PHP/SQL):**
```php
// Direct SQL in presentation layer
$stmt = $pdo->prepare("SELECT * FROM participants...");
$participants = $stmt->fetchAll();
// HTML mixed with PHP logic
```

### **After (Clean API):**
```javascript
// Clean API calls
const participants = await apiCall('GET', 'get_participants', {
  event_id: eventId,
  heat_number: heat,
  run_number: run
});
// Pure HTML/JS presentation
```

## **🔍 Debug Data Example**

When you open the debug panel, you'll see real-time data like:

```json
{
  "incoming_data": {
    "event_info": "Live event context",
    "judge_info": "Current judge session", 
    "participant_info": "Selected participant details",
    "form_data": "Current form state"
  },
  "api_calls": [
    {
      "method": "GET",
      "action": "get_participants", 
      "status": "success",
      "duration": "145ms",
      "timestamp": "2025-08-23T06:04:45.149Z"
    }
  ]
}
```

This provides complete visibility into the application's data flow and API performance.
