# Judge Status Feature - Implementation Summary

## Overview
Added a complete judge status system that allows judges to set their current status from the scoring panel. Status is visible to head judges and event coordinators.

## Components Created

### 1. Database Migration
**Files:**
- `add_judge_status_columns.sql` - SQL migration script
- `add_judge_status_migration.php` - PHP migration script (✓ executed successfully)

**Changes to `judge_assignments` table:**
- Added `status` column (VARCHAR(20), default: 'ready')
- Added `status_updated_at` column (DATETIME, nullable)
- Added indexes: `idx_status`, `idx_status_updated`

**Valid Status Values:**
- `ready` - Judge is ready to score (Green)
- `pending` - Judge is waiting/preparing (Yellow)
- `danger` - Critical issue/problem (Red)
- `warning` - Minor issue/attention needed (Yellow)
- `info` - Informational status (Blue)
- `off` - Judge is offline/unavailable (Gray)

### 2. API Endpoint
**File:** `api/judge_status_api.php`

**Endpoints:**

#### POST - Update Judge Status

Content-Type: application/json

{
  "event_id": 6,
  "judge_id": 1,
  "status": "ready",
  "timestamp": "2025-11-11 07:50:55"
}
```

**Response:**
```json
{
  "success": true,
  "message": "Judge status updated successfully",
  "data": {
    "event_id": 6,
    "judge_id": 1,
    "status": "ready",
    "timestamp": "2025-11-11 07:50:55"
  }
}
```

#### GET - Retrieve Judge Status

```
GET /api/judge_status_api.php?event_id=6&judge_id=1
```

**Get all judges for event:**
```
GET /api/judge_status_api.php?event_id=6
```

**Response:**
```json
{
  "success": true,
  "count": 2,
  "data": [
    {
      "id": 372,
      "event_id": 6,
      "judge_id": 1,

}
```

### 3. Frontend UI (score.php)
**Location:** Lines 2377-2400

**Features:**
- Dropdown selector with 6 status options
- Color-coded visual feedback
- Icon changes based on status
- Card header changes color
- Auto-saves to localStorage
- Sends updates to server

**JavaScript Functions:**
- `handleJudgeStatusChange()` - Handles status changes
- `updateJudgeStatusUI()` - Updates visual styling
- `saveJudgeStatus()` - Persists to localStorage
- `loadJudgeStatus()` - Restores on page load
- `sendJudgeStatusToServer()` - API communication

### 4. Test Files
**Files:**
- `test_judge_status_api.php` - API endpoint tests
- `check_judges_table.php` - Database structure verification
- `check_judge_assignments.php` - Data verification
- `check_judges.php` - Judge records check

## Testing Results

✅ **Database Migration:** Successfully added columns and indexes
✅ **POST Requests:** Status updates working correctly
✅ **GET Requests:** Data retrieval working (when judges exist in judges table)
✅ **Validation:** Invalid status values properly rejected
✅ **UI Integration:** Status selector added to score panel
✅ **Persistence:** localStorage saves/restores status

## Usage

### For Judges:
1. Open score panel
2. Find "Judge Status" card above participant selection
3. Select status from dropdown
4. Status is automatically saved and sent to server

### For Administrators:
To retrieve all judge statuses for monitoring:
```php
$response = file_get_contents('http://localhost/v2/api/judge_status_api.php?event_id=6');
$data = json_decode($response, true);
foreach($data['data'] as $judge) {
    echo "{$judge['judge_name']}: {$judge['status']}\n";
}
```

## Next Steps (Optional Enhancements)

1. **Create Admin Dashboard** - Display all judge statuses in real-time
2. **Add Notifications** - Alert head judge when judge sets "danger" status
3. **Status History** - Log status changes for event timeline
4. **Mobile Optimization** - Ensure status selector works on tablets
5. **Status Presets** - Allow customizing status options per event
