# EngineerDetails

## 1. Purpose  
This module defines the core view and view model interfaces for the *Engineer Details* feature within the DTS (likely *Design & Technical Services*) system. It serves as a contract layer in a MVVM (Model-View-ViewModel) architecture, decoupling UI presentation logic from implementation details. The interfaces `IEngineerDetailsView` and `IEngineerDetailsViewModel` extend base abstractions (`IBaseView`, `IBaseViewModel`) to signal that this feature adheres to the common architectural patterns used across the application, but—based on the provided source—does not yet expose any domain-specific data or commands, indicating either an early-stage implementation or a minimal placeholder interface set.

## 2. Public Interface  
No public *members* (methods, properties, events) are defined on the interfaces themselves beyond inheritance. However, the public *types* are:

- **`IEngineerDetailsView`**  
  *Signature:* `public interface IEngineerDetailsView : IBaseView`  
  *Behavior:* Represents the view layer contract for the Engineer Details feature. As it inherits `IBaseView`, it is expected to support standard view lifecycle or binding behaviors defined in the base interface (e.g., data context assignment, initialization hooks), though those specifics are not visible in this file.

- **`IEngineerDetailsViewModel`**  
  *Signature:* `public interface IEngineerDetailsViewModel : IBaseViewModel`  
  *Behavior:* Represents the view model layer contract for the Engineer Details feature. As it inherits `IBaseViewModel`, it is expected to expose standard view model capabilities (e.g., property change notification via `INotifyPropertyChanged`, command support), but no engineer-specific properties (e.g., `EngineerId`, `Name`, `Skills`) or commands (e.g., `SaveCommand`) are declared here.

## 3. Invariants  
- Both interfaces are *marker interfaces*—they carry no additional constraints beyond their base interface contracts.  
- They must be implemented by concrete types that conform to the semantics of `IBaseView` and `IBaseViewModel`, respectively (e.g., view models must support property change notifications, views must bind to a view model).  
- No validation rules, ordering guarantees, or state invariants are specified at this level.

## 4. Dependencies  
- **Depends on:**  
  - `DTS.Common.Base` namespace (specifically `IBaseView` and `IBaseViewModel`, though their definitions are not included here).  
- **Depended on by:**  
  - Likely concrete implementations of the view (e.g., `EngineerDetailsView : IEngineerDetailsView`) and view model (e.g., `EngineerDetailsViewModel : IEngineerDetailsViewModel`).  
  - Dependency injection containers or navigation frameworks may use these interfaces to resolve or inject the engineer details feature components.  
  - Other modules (e.g., navigation, routing, or feature registration logic) may reference these interfaces to integrate the Engineer Details feature into the larger application.

## 5. Gotchas  
- **No domain exposure:** Despite the feature name, the interfaces contain *no* engineer-related properties or methods (e.g., no `Engineer` model, `LoadCommand`, or `IsLoading` flag). This may mislead developers into expecting functionality that is not yet implemented or resides elsewhere.  
- **Base interface assumptions:** Behavior is entirely inherited from `IBaseView`/`IBaseViewModel`. Without access to those base definitions, the full contract is incomplete—e.g., it is unclear if `IBaseView` requires a `ViewModel` property or if `IBaseViewModel` includes `InitializeAsync`.  
- **Placeholder status:** These interfaces may be scaffolding for future work; relying on them as complete contracts could lead to runtime errors if consumers expect non-existent members.  
- **Namespace ambiguity:** The namespace `DTS.Common.Interface` (instead of `DTS.Common.Interface.EngineerDetails`) suggests possible inconsistency in module scoping, though this is a design choice rather than a bug.
