+# Documentation: Customer Details Interfaces
+
+## 1. Purpose
+
+This module defines two marker interfaces—`ICustomerDetailsView` and `ICustomerDetailsViewModel`—that establish type identity for customer details components within a Model-View-ViewModel (MVVM) architecture. These interfaces exist to provide a contract for customer-specific views and view models, enabling type-safe binding, dependency injection, and navigation patterns while inheriting core behaviors from base interfaces in the `DTS.Common.Base` namespace.
+
+---
+
+## 2. Public Interface
+
+### `ICustomerDetailsView`
+- **Namespace:** `DTS.Common.Interface`
+- **Inheritance:** `IBaseView` (from `DTS.Common.Base`)
+- **Signature:**
+  ```csharp
+  public interface ICustomerDetailsView : IBaseView { }
+  ```
+- **Behavior:** Empty marker interface. Any concrete view implementing this interface signals that it represents a customer details screen. All actual behavior and members are inherited from `IBaseView`.
+
+### `ICustomerDetailsViewModel`
+- **Namespace:** `DTS.Common.Interface`
+- **Inheritance:** `IBaseViewModel` (from `DTS.Common.Base`)
+- **Signature:**
+  ```csharp
+  public interface ICustomerDetailsViewModel : IBaseViewModel { }
+  ```
+- **Behavior:** Empty marker interface. Any concrete view model implementing this interface signals that it provides the presentation logic for a customer details view. All actual behavior and members are inherited from `IBaseViewModel`.
+
+---
+
+## 3. Invariants
+
+- **Type identity guarantee:** Any class implementing `ICustomerDetailsView` or `ICustomerDetailsViewModel` must also satisfy the contracts of `IBaseView` or `IBaseViewModel` respectively.
+- **No additional members:** Neither interface defines its own properties, methods, or events; they rely entirely on their base interfaces for functionality.
+- **Naming convention:** The interfaces follow a naming pattern suggesting a 1:1 correspondence between `ICustomerDetailsView` and `ICustomerDetailsViewModel`.
+
+**Note:** Specific invariants regarding `IBaseView` and `IBaseViewModel` cannot be determined from the provided source files.
+
+---
+
+## 4. Dependencies
+
+### This module depends on:
+- `DTS.Common.Base` — Provides `IBaseView` and `IBaseViewModel` base interfaces.
+
+### What depends on this module:
+- Cannot be determined from the provided source files alone. Likely consumers include:
+  - Concrete view implementations (e.g., WinForms, WPF, or web views displaying customer details)
+  - Concrete view model implementations for customer details
+  - Navigation or routing services that resolve views by interface type
+  - Dependency injection configurations
+
+---
+
+## 5. Gotchas
+
+- **Empty marker interfaces:** Both interfaces define no members of their own. If `IBaseView` and `IBaseViewModel` also lack meaningful members, these interfaces serve purely as type markers. This design is intentional for type discrimination but may confuse developers expecting explicit contracts.
+- **Base interface contracts unknown:** The actual capabilities and requirements of these interfaces are entirely determined by `IBaseView` and `IBaseViewModel`. Developers must consult those base definitions to understand what members must be implemented.
+- **Potential tight coupling to base types:** Any changes to `IBaseView` or `IBaseViewModel` will ripple to all implementers of these customer details interfaces.
