+# Documentation: IQASettingsView and IQASettingsViewModel Interfaces
+
+## 1. Purpose
+
+This module defines two marker interfaces, `IQASettingsView` and `IQASettingsViewModel`, which represent the View and ViewModel contracts for a QA (Quality Assurance) Settings feature within the system settings domain. These interfaces follow the Model-View-ViewModel (MVVM) architectural pattern and serve as extension points for concrete implementations, inheriting from base view and viewmodel abstractions. Their role is to provide type identity for QA settings-related views and viewmodels within the DTS application framework.
+
+## 2. Public Interface
+
+### `IQASettingsView`
+- **Namespace:** `DTS.Common.Interface`
+- **Declaration:** `public interface IQASettingsView : IBaseView { }`
+- **Inheritance:** Extends `IBaseView` from `DTS.Common.Base`
+- **Members:** None defined
+- **Behavior:** Serves as a marker interface for QA Settings view implementations. Any concrete view implementing this interface must also satisfy the `IBaseView` contract.
+
+### `IQASettingsViewModel`
+- **Namespace:** `DTS.Common.Interface`
+- **Declaration:** `public interface IQASettingsViewModel : IBaseViewModel { }`
+- **Inheritance:** Extends `IBaseViewModel` from `DTS.Common.Base`
+- **Members:** None defined
+- **Behavior:** Serves as a marker interface for QA Settings viewmodel implementations. Any concrete viewmodel implementing this interface must also satisfy the `IBaseViewModel` contract.
+
+## 3. Invariants
+
+- Any class implementing `IQASettingsView` must also implement all members of `IBaseView` (exact members unspecified in provided source).
+- Any class implementing `IQASettingsViewModel` must also implement all members of `IBaseViewModel` (exact members unspecified in provided source).
+- Both interfaces are public and must remain accessible for external implementations.
+- The interfaces define no additional members beyond their base interfaces, implying they are intended purely for type discrimination or future extensibility.
+
+## 4. Dependencies
+
+### This module depends on:
+- `DTS.Common.Base` — Provides `IBaseView` and `IBaseViewModel` base interfaces that these interfaces extend.
+
+### What depends on this module:
+- **Cannot be determined from source alone.** Concrete view and viewmodel classes implementing these interfaces, as well as any registration, navigation, or dependency injection infrastructure that resolves these types, would depend on this module.
+
+## 5. Gotchas
+
+- **Empty marker interfaces:** Both interfaces define no members of their own. The rationale for having separate interfaces rather than using `IBaseView`/`IBaseViewModel` directly is not clear from the source—it may be for type identification, dependency injection registration, or future extensibility.
+- **Base interface contracts unknown:** The actual requirements imposed by `IBaseView` and `IBaseViewModel` are not visible in the provided source, making it unclear what implementers must provide.
+- **Naming convention:** The file path (`SystemSettings/QASettings`) suggests these are part of a larger settings hierarchy, but the relationship to other settings interfaces is not documented in the source.
