# Phase 1 Completion Summary - Backend Enhancements

## Completed Tasks

### 1. ✅ Action Categories Endpoint
**Endpoint:** `GET /api/v1/configuration/action-categories`

**Response Format:**
```json
{
  "categories": {
    "Camera Control": ["PanLeft", "PanRight", "PanStop", ...],
    "Video Switching": ["CrossSwitch C -> M", "CrossSwitch OpCon -> Matrix"],
    "System": ["SystemWarning", "SystemError", ...],
    ...
  },
  "total_categories": 10,
  "total_actions": 45
}
```

**Categories Available:**
- **Camera Control** (22 actions) - Pan, Tilt, Zoom, Focus, Iris, Presets, Movement
- **System** (7 actions) - Warnings, Errors, Info, Video sync/contrast notifications
- **Viewer** (3 actions) - Live connections, disconnections
- **Events** (3 actions) - Start, Stop, Kill
- **Digital I/O** (2 actions) - Contact activation/deactivation
- **Recording** (2 actions) - Start/Stop recording
- **Video Switching** (2 actions) - CrossSwitch operations
- **Custom** (2 actions) - GSC and GNG custom actions
- **Alarms** (1 action) - Alarm recording
- **Input** (1 action) - Input contact triggers

### 2. ✅ Enhanced Action Templates
All action templates now include:
- **description** - Detailed description of what the action does
- **category** - Category for organization
- **required_caption** - Whether a caption field is required
- **supports_delay** - Whether delay execution is supported
- **parameter_types** (optional) - Data types for parameters

**Example Enhanced Template:**
```json
{
  "action_name": "PanStop",
  "parameters": ["GCoreServer", "PTZ head"],
  "description": "Stop pan movement. The panning of the camera will be stopped.",
  "category": "Camera Control",
  "required_caption": true,
  "supports_delay": true
}
```

### 3. ✅ Expanded Action Library
Increased from 30 to **45 actions** covering:

**Camera Control:**
- Basic: Pan, Tilt, Zoom, Focus, Iris operations
- Advanced: Move to absolute/relative position, Move by speed, Auto pan
- Presets: Save and recall preset positions

**System Actions:**
- SystemWarning, SystemError, SystemInfo
- VideoSyncFailure, VideoSyncOk
- VideoContrastAlarm, VideoContrastOk

**Video Actions:**
- ViewerConnectLive (with parameters)
- CrossSwitch operations

**Custom Actions:**
- GscCustomAction - for custom GSC commands
- GNGCustomAction - for custom GNG commands

**Input Actions:**
- InputContact - for digital input triggers

## API Endpoints Summary

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/v1/configuration/action-types` | GET | Get all action templates |
| `/api/v1/configuration/action-types/{name}` | GET | Get specific action template |
| `/api/v1/configuration/action-categories` | GET | Get actions grouped by category |

## Testing Results

All endpoints tested and working:
- ✅ Categories endpoint returns 10 categories with 45 actions
- ✅ Action templates include enhanced metadata
- ✅ Descriptions match native GeViSet app
- ✅ Parameter types defined for form generation

## Usage for Flutter App

### 1. On App Startup - Load Categories
```dart
final response = await http.get(
  Uri.parse('$apiUrl/action-categories'),
  headers: {'Authorization': 'Bearer $token'},
);

final categories = jsonDecode(response.body)['categories'];
// categories = {
//   "Camera Control": ["PanLeft", "PanRight", ...],
//   "Video Switching": [...],
//   ...
// }
```

### 2. Build Category Dropdown
```dart
DropdownButton<String>(
  value: selectedCategory,
  items: categories.keys.map((category) =>
    DropdownMenuItem(value: category, child: Text(category))
  ).toList(),
  onChanged: (category) {
    setState(() {
      selectedCategory = category;
      // Load actions for this category
    });
  },
)
```

### 3. Display Actions in Category
```dart
ListView.builder(
  itemCount: categories[selectedCategory].length,
  itemBuilder: (context, index) {
    final actionName = categories[selectedCategory][index];
    return ListTile(
      title: Text(actionName),
      onTap: () => _selectAction(actionName),
    );
  },
)
```

### 4. Show Action Details
```dart
// Fetch full action template
final response = await http.get(
  Uri.parse('$apiUrl/action-types/$actionName'),
  headers: {'Authorization': 'Bearer $token'},
);

final template = jsonDecode(response.body);

// Show description
Text(template['description']);

// Generate parameter fields
for (var param in template['parameters']) {
  TextField(
    decoration: InputDecoration(labelText: param),
  );
}

// Show caption field if required
if (template['required_caption'] == true) {
  TextField(
    decoration: InputDecoration(labelText: 'Caption (required)'),
  );
}

// Show delay field if supported
if (template['supports_delay'] == true) {
  TextField(
    decoration: InputDecoration(
      labelText: 'Delay execution',
      suffixText: 'ms',
    ),
  );
}
```

## Files Modified

1. **C:\DEV\COPILOT\geutebruck-api\src\api\routers\configuration.py**
   - Added 15 new action templates
   - Enhanced existing templates with metadata
   - Added `/action-categories` endpoint
   - Total action count: 30 → 45

## Next Steps (Phase 2 & 3)

### Phase 2: Flutter UI Components
1. Create ActionPickerDialog with two-pane layout
2. Implement category dropdown + action list
3. Build dynamic parameter fields based on templates
4. Add description display at bottom
5. Add caption and delay execution fields

### Phase 3: DataTable Main View
1. Replace card-based list with DataTable
2. Show multiple output actions as columns
3. Add row selection
4. Implement Add/Edit/Remove buttons

### Phase 4: Full Integration
1. Wire up ActionPickerDialog to mapping editor
2. Implement output action reordering
3. Add validation for required fields
4. Test full workflow: List → Edit → Pick Action → Set Parameters → Save

## Performance Notes

- All action templates loaded in-memory (45 templates = ~10KB)
- Categories computed on-demand (fast, <1ms)
- Action names sorted alphabetically within categories
- No database queries - all static data

## Backward Compatibility

✅ All existing endpoints remain unchanged:
- `/action-mappings` - Still works, now includes `output_action_names`
- `/action-types` - Still works, now includes enhanced metadata
- New `/action-categories` endpoint is additive

## Ready for Flutter Development

The backend is now ready for Flutter app Phase 2 development. All necessary data is available through clean REST APIs with proper authentication and authorization.
