# Documentation: LabDetails Interfaces

## 1. Purpose

This module defines four marker interfaces for the LabDetails feature within an MVVM (Model-View-ViewModel) architecture. The interfaces establish type contracts for two distinct UI components: a main LabDetails view with its corresponding view model, and a LabDetails menu view integrated with a ribbon control system. These interfaces enable dependency injection, testability, and loose coupling between UI components and their consumers.

## 2. Public Interface

### ILabDetailsView
**Signature:** `public interface ILabDetailsView : IBaseView { }`

A marker interface extending `IBaseView`. Represents the main view contract for LabDetails functionality. No members are defined beyond those inherited from `IBaseView`.

---

### ILabDetailsViewModel
**Signature:** `public interface ILabDetailsViewModel : IBaseViewModel { }`

A marker interface extending `IBaseViewModel`. Represents the view model contract paired with `ILabDetailsView`. No members are defined beyond those inherited from `IBaseViewModel`.

---

### ILabDetailsMenuView
**Signature:** `public interface ILabDetailsMenuView : IRibbonView { }`

A marker interface extending `IRibbonView`. Represents a menu view contract for LabDetails that integrates with a ribbon control system. No members are defined beyond those inherited from `IRibbonView`.

---

### ILabDetailsMenuViewModel
**Signature:** `public interface ILabDetailsMenuViewModel : IRibbonViewModel { }`

A marker interface extending `IRibbonViewModel`. Represents the view model contract paired with `ILabDetailsMenuView`. No members are defined beyond those inherited from `IRibbonViewModel`.

## 3. Invariants

- Each view interface (`ILabDetailsView`, `ILabDetailsMenuView`) must have a corresponding view model interface (`ILabDetailsViewModel`, `ILabDetailsMenuViewModel`) following the MVVM pairing pattern.
- All interfaces are marker interfaces with no additional members; any behavioral contracts are inherited from their respective base interfaces (`IBaseView`, `IBaseViewModel`, `IRibbonView`, `IRibbonViewModel`).
- The specific invariants enforced by `IBaseView`, `IBaseViewModel`, `IRibbonView`, and `IRibbonViewModel` are not visible in the provided source.

## 4. Dependencies

### This module depends on:
- `DTS.Common.Base` — provides `IBaseView` and `IBaseViewModel` base types
- `DTS.Common.RibbonControl` — provides `IRibbonView` and `IRibbonViewModel` base types

### What depends on this module:
- Not determinable from the provided source alone. Consumers would typically include concrete implementations of these interfaces and any modules that reference LabDetails views or view models through these contracts.

## 5. Gotchas

- **Marker interfaces:** All four interfaces define no members of their own. They serve purely
