# Documentation: ICheckTriggerView and ICheckTriggerViewModel

## 1. Purpose

This module defines two marker interfaces—`ICheckTriggerView` and `ICheckTriggerViewModel`—that establish the View and ViewModel contracts for a "CheckTrigger" feature within an MVVM (Model-View-ViewModel) architecture. These interfaces serve as type identifiers, inheriting from base framework interfaces (`IBaseView` and `IBaseViewModel` respectively) without adding additional members. They exist to enable type-safe binding, dependency injection, or navigation registration within the DTS.CommonCore system.

## 2. Public Interface

### `ICheckTriggerView`
- **Signature:** `public interface ICheckTriggerView : IBaseView { }`
- **Namespace:** `DTS.Common.Interface`
- **Behavior:** Empty marker interface extending `IBaseView`. Provides no additional members beyond those inherited from `IBaseView`. Intended to be implemented by View components associated with CheckTrigger functionality.

### `ICheckTriggerViewModel`
- **Signature:** `public interface ICheckTriggerViewModel : IBaseViewModel { }`
- **Namespace:** `DTS.Common.Interface`
- **Behavior:** Empty marker interface extending `IBaseViewModel`. Provides no additional members beyond those inherited from `IBaseViewModel`. Intended to be implemented by ViewModel components associated with CheckTrigger functionality.

## 3. Invariants

- Any class implementing `ICheckTriggerView` must also satisfy the contract of `IBaseView` (defined in `DTS.Common.Base`).
- Any class implementing `ICheckTriggerViewModel` must also satisfy the contract of `IBaseViewModel` (defined in `DTS.Common.Base`).
- The actual member requirements for these interfaces are determined entirely by their base interfaces, which are not shown in the provided source.

## 4. Dependencies

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

### What depends on this module:
- **Unclear from source alone.** Consumers would include any View or ViewModel classes implementing these interfaces, as well as any navigation, routing, or dependency injection infrastructure that registers or resolves these types.

## 5. Gotchas

- **Marker interfaces with no members:** Neither interface defines any properties, methods, or events. All contractual behavior is inherited from `IBaseView` and `IBaseViewModel`. Developers implementing these interfaces must consult the base interface definitions to understand required members.
- **Naming convention:** The "CheckTrigger" naming suggests a specific feature domain, but the purpose and behavior of this feature cannot be determined from these interface definitions alone.
- **No explicit View-ViewModel pairing:** While the naming suggests these interfaces are paired (View/ViewModel), there is no compile-time enforcement of this relationship in the source.
