# Documentation: CheckChannels Interfaces

## 1. Purpose

This module defines four marker interfaces for the CheckChannels feature within the DTS application, following the Model-View-ViewModel (MVVM) architectural pattern. These interfaces establish contracts for View and ViewModel components, separating the main CheckChannels view from its Ribbon-based menu interface. They serve as extension points for type identification, dependency injection, and navigation registration within the broader system.

## 2. Public Interface

### `ICheckChannelsView`
- **Namespace:** `DTS.Common.Interface`
- **Inherits from:** `DTS.Common.Base.IBaseView`
- **Signature:** `public interface ICheckChannelsView : IBaseView { }`
- **Description:** Marker interface for the primary CheckChannels view. Defines no additional members beyond its base interface.

### `ICheckChannelsViewModel`
- **Namespace:** `DTS.Common.Interface`
- **Inherits from:** `DTS.Common.Base.IBaseViewModel`
- **Signature:** `public interface ICheckChannelsViewModel : IBaseViewModel { }`
- **Description:** Marker interface for the CheckChannels ViewModel. Defines no additional members beyond its base interface.

### `ICheckChannelsMenuView`
- **Namespace:** `DTS.Common.Interface`
- **Inherits from:** `DTS.Common.RibbonControl.IRibbonView`
- **Signature:** `public interface ICheckChannelsMenuView : IRibbonView { }`
- **Description:** Marker interface for the CheckChannels Ribbon menu view. Defines no additional members beyond its base interface.

### `ICheckChannelsMenuViewModel`
- **Namespace:** `DTS.Common.Interface`
- **Inherits from:** `DTS.Common.RibbonControl.IRibbonViewModel`
- **Signature:** `public interface ICheckChannelsMenuViewModel : IRibbonViewModel { }`
- **Description:** Marker interface for the CheckChannels Ribbon menu ViewModel. Defines no additional members beyond its base interface.

## 3. Invariants

- All four interfaces are marker interfaces with no additional members; any invariants must be defined by their respective base interfaces (`IBaseView`, `IBaseViewModel`, `IRibbonView`, `IRibbonViewModel`).
- The View/ViewModel pairing convention implies that `ICheckChannelsView` should be paired with `ICheckChannelsViewModel`, and `ICheckChannelsMenuView` should be paired with `ICheckChannelsMenuViewModel`.
- The separation of "Menu" interfaces suggests a distinction between the main view and a Ribbon-specific menu view, but specific behavioral constraints are not defined in these interfaces.

## 4. Dependencies

### This module depends on:
- `DTS.Common.Base` — provides `IBaseView` and `IBaseViewModel` base interfaces
- `DTS.Common.RibbonControl` — provides `IRibbonView` and `IRibbonViewModel`
