# Documentation: IRealtimeSettingsView and IRealtimeSettingsViewModel

## 1. Purpose

This module defines two marker interfaces—`IRealtimeSettingsView` and `IRealtimeSettingsViewModel`—for the RealtimeSettings feature within the SystemSettings domain. These interfaces follow the Model-View-ViewModel (MVVM) pattern, establishing type identity for views and view models that handle real-time system configuration. They serve as extension points for concrete implementations while maintaining consistency with the broader application architecture through their base interfaces.

## 2. Public Interface

### `IRealtimeSettingsView`
- **Namespace:** `DTS.Common.Interface`
- **Signature:** `public interface IRealtimeSettingsView : IBaseView { }`
- **Behavior:** An empty marker interface that inherits from `IBaseView`. It provides no additional members beyond those defined in its base interface. Used to identify view components responsible for rendering real-time settings UI.

### `IRealtimeSettingsViewModel`
- **Namespace:** `DTS.Common.Interface`
- **Signature:** `public interface IRealtimeSettingsViewModel : IBaseViewModel { }`
- **Behavior:** An empty marker interface that inherits from `IBaseViewModel`. It provides no additional members beyond those defined in its base interface. Used to identify view model components that manage state and logic for real-time settings.

## 3. Invariants

- Any class implementing `IRealtimeSettingsView` must also fulfill the contract of `IBaseView`.
- Any class implementing `IRealtimeSettingsViewModel` must also fulfill the contract of `IBaseViewModel`.
- The exact members required by `IBaseView` and `IBaseViewModel` are not visible in the provided source; their contracts must be obtained from `DTS.Common.Base` to understand full implementation requirements.

## 4. Dependencies

### This module depends on:
- `DTS.Common.Base` — Provides `IBaseView` and `IBaseViewModel` base interfaces.

### What depends on this module:
- **Cannot be determined from source alone.** Consumers would typically be concrete view and view model classes within the `SystemSettings/RealtimeSettings` feature area, but no implementations are shown in the provided files.

## 5. Gotchas

- **Empty interfaces:** Both interfaces define no members of their own. This suggests they are either:
  - Marker interfaces used solely for type identification/registration purposes.
  - Work-in-progress placeholders where domain-specific members have not yet been defined.
  
- **Base interface contracts unknown:** Without visibility into `IBaseView` and `IBaseViewModel`, developers cannot determine what methods, properties, or events must be implemented to satisfy these interfaces.

- **File path vs. namespace mismatch:** The files are located in `Common/DTS.Common/Interface/SystemSettings/RealtimeSettings/`, but the declared namespace is `DTS.Common.Interface`. The subfolders (`SystemSettings/RealtimeSettings`) do not affect the namespace, which may cause confusion when locating types.
