IPC Bridge Communication

Communication between the React frontend and the C# host takes place via bi-directional JSON messaging over Edge WebView2.

Bridge Infrastructure (src/infrastructure/bridge.ts)​

The frontend dispatches typed actions to C#:

export function sendAction(action: string, payload?: Record<string, any>): void {
  if (window.chrome?.webview) {
    window.chrome.webview.postMessage(JSON.stringify({ action, ...payload }));
  }
}

C# Event Dispatch (desktop/MainWindow.xaml.cs)​

The WPF host listens for WebView2 messages and routes them to Optimizer or host managers:

private async void OnWebMessageReceived(object sender, CoreWebView2WebMessageReceivedEventArgs e)
{
    var message = e.TryGetWebMessageAsString();
    // Dispatch action and emit progress/logs back to React
}

When an action finishes, C# emits window.onActionFinished(action, ok) to safely release the UI action lock.
