# Reactor Maintenance

C# WinUI 3 + Win2D level editor for the deterministic grid simulation described in `docs/design.md`.

## Projects

- `src/ReactorMaintenance.Simulation`: UI-independent level model, editor operations, validation, forecasts, simulation turns, versioned JSON serialization, and deterministic balancing defaults.
- `src/ReactorMaintenance.Win2D`: Win2D editor app for authoring terrain, underground fuel/coolant/electricity networks, props, leaks, doors, surface hazards, robot start, loading/saving levels, ending turns, interacting with props, and activating a ready reactor.
- `tests/ReactorMaintenance.Simulation.Tests`: unit tests for deterministic simulation behavior.

## Commands

```powershell
dotnet test tests\ReactorMaintenance.Simulation.Tests\ReactorMaintenance.Simulation.Tests.csproj
dotnet build src\ReactorMaintenance.Win2D\ReactorMaintenance.Win2D.csproj -p:Platform=x64 -p:EnableWindowsTargeting=true
dotnet run --project src\ReactorMaintenance.Win2D\ReactorMaintenance.Win2D.csproj -p:Platform=x64
```

The WinUI/XAML compiler is Windows-specific. On Linux, the simulation tests run normally, but the Win2D app build must be verified in a Windows-capable environment.
