Wire DI composition root

[Sstark97]

Phase 5: CLI Presentation

Wire dependency injection composition root and verify AOT compilation.

ServiceRegistration

In Infrastructure/Cli/Composition/ServiceRegistration.cs

Register all services:

public static class ServiceRegistration
{
    public static IServiceCollection AddDevSweepServices(
        this IServiceCollection services,
        OutputFormat outputFormat,
        bool autoConfirm)
    {
        // Domain services
        services.AddSingleton<VersionSorter>();
        
        // Use cases
        services.AddScoped<IAnalyzeUseCase, AnalyzeUseCase>();
        services.AddScoped<ICleanupUseCase, CleanupUseCase>();
        services.AddScoped<IModuleDiscoveryUseCase, ModuleDiscoveryUseCase>();
        
        // Infrastructure adapters
        services.AddSingleton<IFileSystem, PhysicalFileSystem>();
        services.AddSingleton<IProcessManager, SystemProcessManager>();
        services.AddSingleton<ICommandRunner, SystemCommandRunner>();
        services.AddSingleton<IEnvironmentProvider, SystemEnvironmentProvider>();
        
        // Output formatter strategy
        services.AddSingleton<IOutputFormatter>(sp => outputFormat switch
        {
            OutputFormat.Rich => new SpectreOutputFormatter(),
            OutputFormat.Plain => new PlainTextOutputFormatter(),
            OutputFormat.Json => new JsonOutputFormatter(),
            _ => new SpectreOutputFormatter()
        });
        
        // Interaction strategy
        services.AddSingleton<IUserInteraction>(sp => autoConfirm
            ? new AutoConfirmInteraction()
            : new InteractiveConsole());
        
        // Module registry
        var registry = new ModuleRegistry();
        registry.Register(new JetBrainsModule());
        registry.Register(new DockerModule());
        registry.Register(new HomebrewModule());
        registry.Register(new DevToolsModule());
        registry.Register(new StaleProjectsModule());
        registry.Register(new SystemModule());
        services.AddSingleton(registry);
        
        return services;
    }
}

Program.cs

Entry point with DI setup:

var services = new ServiceCollection();
services.AddDevSweepServices(outputFormat, autoConfirm);

var provider = services.BuildServiceProvider();
var analyzeUseCase = provider.GetRequiredService<IAnalyzeUseCase>();
// Execute command...

AOT Verification

• Verify dotnet publish -c Release -r osx-arm64 succeeds
• Check for AOT warnings (trim analysis)
• Verify binary runs: ./devsweep --help
• Test published binary size (~10-15MB target)
• Verify cold start time (<100ms)

Tests Required

In tests/Infrastructure/Cli/Composition/ServiceRegistrationTests.cs:

• All services resolve correctly
• Output formatter strategy selection
• Interaction strategy selection
• Module registry contains all modules

Definition of Done

• ServiceRegistration complete
• Program.cs entry point working
• All services registered and resolvable
• AOT compilation succeeds without warnings
• Published binary tested and functional
• Tests verify DI container configuration
