# Documentation: Engineer Details Interfaces

## 1. Purpose

This module defines two empty marker interfaces, `IEngineerDetailsView` and `IEngineerDetailsViewModel`, which establish the View and ViewModel contracts for an "Engineer Details" feature within the DTS application. These interfaces follow the MVVM (Model-View-ViewModel) architectural pattern and exist primarily to provide type-specific identification and dependency injection registration points by extending base view and view model interfaces.

---

## 2. Public Interface

### `IEngineerDetailsView`
- **Namespace:** `DTS.Common.Interface`
- **Inherits from:** `IBaseView` (from `DTS.Common.Base`)
- **Signature:**
  ```csharp
  public interface IEngineerDetailsView : IBaseView { }
  ```
- **Behavior:** Empty marker interface. No members defined. Relies entirely on the contract defined by `IBaseView`.

---

### `IEngineerDetailsViewModel`
- **Namespace:** `DTS.Common.Interface`
- **Inherits from:** `IBaseViewModel` (from `DTS.Common.Base`)
- **Signature:**
  ```csharp
  public interface IEngineerDetailsViewModel : IBaseViewModel { }
  ```
- **Behavior:** Empty marker interface. No members defined. Relies entirely on the contract defined by `IBaseViewModel`.

---

## 3. Invariants

- Both interfaces are empty and define no additional members beyond their base interfaces.
- Any invariants are inherited from `IBaseView` and `IBaseViewModel` respectively; the specific constraints of those base interfaces are not visible in the provided source.
- Implementations of these interfaces must fulfill the contracts of their respective base types.

---

## 4. Dependencies

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

### What depends on this module:
- **Cannot be determined from source alone.** Consumers would typically include concrete View and ViewModel implementations, dependency injection registration modules, or navigation/routing components within the DTS system.

---

## 5. Gotchas

- **Marker interfaces with no members:** Both interfaces are empty and serve only as type identifiers. They do not define any Engineer Details-specific properties, methods, or events. All functionality must come from the base interfaces or be added via extension methods elsewhere.
- **Base interface contracts unknown:** The actual capabilities and requirements of these interfaces depend entirely on `IBaseView` and `IBaseViewModel`, which are not included in the provided source. Developers should consult those base definitions to understand the full contract.
