# EngineerDetails

## 1. Purpose  
This module defines the foundational view and view model interfaces for the *Engineer Details* feature within the DTS (likely *Dispatch & Tracking System*) application. It serves as a contract layer in a MVVM (Model-View-ViewModel) architecture, decoupling the UI presentation logic (`IEngineerDetailsView`) from its data-binding context (`IEngineerDetailsViewModel`). These interfaces extend base abstractions (`IBaseView`, `IBaseViewModel`) to ensure consistent structural patterns across the application’s modular UI components, specifically for screens displaying or editing engineer-related information.

## 2. Public Interface  
No public *functions*, *properties*, or *methods* are declared directly in either interface beyond their inheritance. Both interfaces are empty markers, inheriting from base abstractions:

- `interface IEngineerDetailsView : IBaseView`  
  Represents the view layer for the Engineer Details feature. As an empty interface, it conveys no behavior beyond its role as a typed marker for dependency injection, navigation, or UI composition (e.g., to bind to a concrete view class like `EngineerDetailsView : IEngineerDetailsView`).

- `interface IEngineerDetailsViewModel : IBaseViewModel`  
  Represents the view model layer for the Engineer Details feature. Similarly empty, it serves as a typed marker for the associated data context, likely used to inject or resolve the correct view model instance (e.g., `EngineerDetailsViewModel : IEngineerDetailsViewModel`). Actual properties (e.g., `Engineer`, `IsReadOnly`, `SaveCommand`) would be defined in the concrete implementation or in `IBaseViewModel`.

## 3. Invariants  
- Both interfaces must be implemented by classes that adhere to the contracts of their respective base interfaces (`IBaseView` and `IBaseViewModel`).  
- The interfaces themselves impose no additional runtime constraints (e.g., validation, state guarantees), as they contain no members.  
- The *engineer-specific* semantics are entirely deferred to implementations and the underlying domain model (e.g., `Engineer` entity), not defined here.

## 4. Dependencies  
- **Depends on**:  
  - `DTS.Common.Base` namespace (specifically `IBaseView` and `IBaseViewModel`).  
- **Depended on by**:  
  - Likely consumed by UI framework code (e.g., navigation services, view resolution logic, dependency injection containers) to resolve or bind view/view model pairs.  
  - Concrete implementations (e.g., `EngineerDetailsView`, `EngineerDetailsViewModel`) in other modules/projects.  
  - *Not inferred*: No direct dependencies *from* this module on other parts of the codebase beyond `DTS.Common.Base`.

## 5. Gotchas  
- **Empty interfaces**: These interfaces carry no behavior—developers must consult concrete implementations (not provided here) to understand actual properties, commands, or lifecycle hooks.  
- **No versioning or extensibility clues**: The interfaces are sealed in purpose but not in extensibility; future engineer-related features (e.g., `IEngineerDetailsViewV2`) may break assumptions if they rely solely on these marker interfaces.  
- **Ambiguity in scope**: "Engineer Details" could imply read-only display, editing, or both—this module does not clarify the feature’s scope.  
- **None identified from source alone.**
