# CheckChannels

## Documentation: CheckChannels Module Interfaces

### 1. Purpose  
This module defines the core interface contracts for the *CheckChannels* feature within the application’s UI architecture. It establishes a separation of concerns between view and view model layers for both the main content area and its associated ribbon menu, following the MVVM pattern. The interfaces `ICheckChannelsView`, `ICheckChannelsViewModel`, `ICheckChannelsMenuView`, and `ICheckChannelsMenuViewModel` collectively enable modular UI composition—allowing implementations to be swapped or extended while adhering to a consistent contract for integration with the broader system.

### 2. Public Interface  
All interfaces are *marker interfaces* with no additional members declared. Their purpose is purely to categorize and type-check components within the UI framework.

- **`ICheckChannelsView`**  
  *Signature:* `public interface ICheckChannelsView : IBaseView`  
  *Behavior:* Serves as the contract for the view component responsible for displaying the primary CheckChannels UI content. Inherits from `IBaseView`, implying it participates in a base view lifecycle or infrastructure (e.g., initialization, data binding setup).

- **`ICheckChannelsViewModel`**  
  *Signature:* `public interface ICheckChannelsViewModel : IBaseViewModel`  
  *Behavior:* Serves as the contract for the view model backing `ICheckChannelsView`. Inherits from `IBaseViewModel`, indicating it likely exposes properties, commands, and state management for the main CheckChannels content.

- **`ICheckChannelsMenuView`**  
  *Signature:* `public interface ICheckChannelsMenuView : IRibbonView`  
  *Behavior:* Serves as the contract for the ribbon menu view associated with CheckChannels. Inherits from `IRibbonView`, implying integration with a ribbon-based UI control system (e.g., a tabbed toolbar with groups and buttons).

- **`ICheckChannelsMenuViewModel`**  
  *Signature:* `public interface ICheckChannelsMenuViewModel : IRibbonViewModel`  
  *Behavior:* Serves as the view model for `ICheckChannelsMenuView`. Inherits from `IRibbonViewModel`, indicating it manages ribbon-specific state (e.g., button visibility, command execution for ribbon items).

### 3. Invariants  
- All four interfaces are *purely marker interfaces*—they carry no additional properties, methods, or events beyond their base interface contracts.  
- `ICheckChannelsView` and `ICheckChannelsViewModel` must be used in conjunction (e.g., via dependency injection or view-model-first patterns) to form a valid view/view-model pair for the main content area.  
- Similarly, `ICheckChannelsMenuView` and `ICheckChannelsMenuViewModel` must be paired for the ribbon menu component.  
- Since they inherit from `IBaseView`, `IBaseViewModel`, `IRibbonView`, and `IRibbonViewModel` respectively, they inherit all invariants and contracts defined in those base interfaces (e.g., lifecycle events, binding requirements), though those are not detailed in this module’s source.

### 4. Dependencies  
- **Depends on:**  
  - `DTS.Common.Base` namespace (for `IBaseView`, `IBaseViewModel`)  
  - `DTS.Common.RibbonControl` namespace (for `IRibbonView`, `IRibbonViewModel`)  
- **Depended on by:**  
  - UI framework components that resolve or validate view/view-model types by interface (e.g., a DI container, view factory, or navigation service).  
  - Concrete implementations (not present in this source) for `ICheckChannelsView`, `ICheckChannelsViewModel`, `ICheckChannelsMenuView`, and `ICheckChannelsMenuViewModel`.  
  - Likely consumed by modules responsible for UI composition (e.g., shell layout, ribbon registration, or module initialization logic in a modular application architecture).

### 5. Gotchas  
- **No behavior defined:** These interfaces convey *no operational semantics*—all functionality resides in their implementations. Developers must inspect concrete classes to understand actual behavior.  
- **Ambiguous scope:** The term “CheckChannels” is not defined here; its functional meaning (e.g., channel validation, configuration, monitoring) is external to this module.  
- **Inheritance chain opacity:** Since `IBaseView`, `IBaseViewModel`, `IRibbonView`, and `IRibbonViewModel` are defined elsewhere, their contracts (e.g., required properties like `DataContext`, event handlers, or initialization methods) must be referenced separately to fully understand the obligations of these interfaces.  
- **No versioning or deprecation markers:** No attributes (e.g., `[Obsolete]`) or versioning hints are present, suggesting these are stable but potentially low-level abstractions.  

None identified from source alone beyond the above.
