# PowerAndBattery

### Purpose
This module defines the contract interfaces for the Power and Battery settings feature within the system settings hierarchy. It follows the Model-View-ViewModel (MVVM) pattern, providing empty marker interfaces that extend base view and view model contracts, allowing concrete implementations to be injected and swapped at runtime.

### Public Interface

**`IPowerAndBatteryView`** (`IPowerAndBatteryView.cs`)
- **Signature:** `public interface IPowerAndBatteryView : IBaseView { }`
- **Behavior:** Marker interface for Power and Battery settings views. Inherits from `IBaseView` but defines no additional members.

**`IPowerAndBatteryViewModel`** (`IPowerAndBatteryViewModel.cs`)
- **Signature:** `public interface IPowerAndBatteryViewModel : IBaseViewModel { }`
- **Behavior:** Marker interface for Power and Battery settings view models. Inherits from `IBaseViewModel` but defines no additional members.

### Invariants
- Both interfaces must remain empty marker interfaces, relying entirely on their base contracts (`IBaseView`, `IBaseViewModel`) for functionality.
- The View-ViewModel pairing is implied by naming convention but not enforced at compile time.

### Dependencies
- **Depends on:** `DTS.Common.Base` (specifically `IBaseView` and `IBaseViewModel`)
- **Dependents:** Unknown from source alone—likely consumed by concrete implementations in a UI layer and dependency injection configuration.

### Gotchas
- The interfaces define no Power/Battery-specific members. Any domain-specific properties or methods must be added to these interfaces or handled through the base interfaces' mechanisms. The current design suggests either a placeholder implementation or that all required behavior is already defined in the base interfaces.
