## Core Integration Points

### 1. Container Integration Hub
```dart
// All packages integrate with Container for dependency injection
class ServiceProvider {
  final Container container;
  
  // Current Integration
  void register() {
    container.registerSingleton<Service>(ServiceImpl());
  }
  
  // Laravel-Compatible Enhancement
  void register() {
    // Add contextual binding
    container.when(Service).needs<Logger>().give(FileLogger());
    
    // Add tagged binding
    container.tag([
      EmailNotifier,
      SmsNotifier,
      PushNotifier
    ], 'notifications');
  }
}
```

### 2. Event System Integration
```dart
// Events package integrates with multiple packages
class EventServiceProvider {
  // Current Integration
  void register() {
    // Queue Integration
    container.singleton<QueuedEventDispatcher>((c) => 
      QueuedEventDispatcher(
        queue: c.make<QueueContract>(),
        broadcaster: c.make<BroadcasterContract>()
      )
    );
    
    // Bus Integration
    container.singleton<CommandDispatcher>((c) =>
      CommandDispatcher(
        events: c.make<EventDispatcherContract>(),
        queue: c.make<QueueContract>()
      )
    );
  }
  
  // Laravel-Compatible Enhancement
  void register() {
    // Add event discovery
    container.singleton<EventDiscovery>((c) =>
      EventDiscovery(c.make<Reflector>())
    );
    
    // Add after commit handling
    container.singleton<DatabaseEventDispatcher>((c) =>
      DatabaseEventDispatcher(
        events: c.make<EventDispatcherContract>(),
        db: c.make<DatabaseManager>()
      )
    );
  }
}
```

### 3. Queue and Bus Integration
```dart
// Queue and Bus packages work together for job handling
class QueuedCommandDispatcher {
  // Current Integration
  Future<void> dispatch(Command command) async {
    if (command is ShouldQueue) {
      await queue.push(QueuedCommandJob(command));
    } else {
      await commandBus.dispatch(command);
    }
  }
  
  // Laravel-Compatible Enhancement
  Future<void> dispatch(Command command) async {
    // Add job middleware
    var job = QueuedCommandJob(command)
      ..through([
        RateLimitedMiddleware(),
        WithoutOverlappingMiddleware()
      ]);
      
    // Add job batching
    if (command is BatchableCommand) {
      await queue.batch([job])
        .allowFailures()
        .dispatch();
    } else {
      await queue.push(job);
    }
  }
}
```

### 4. Route and Core Integration
```dart
// Route package integrates with Core for HTTP handling
class RouterServiceProvider {
  // Current Integration
  void register() {
    container.singleton<Router>((c) =>
      Router()
        ..use(LoggingMiddleware())
        ..use(AuthMiddleware())
    );
  }
  
  // Laravel-Compatible Enhancement
  void register() {
    // Add model binding
    container.singleton<RouteModelBinder>((c) =>
      RouteModelBinder(
        models: c.make<ModelRegistry>(),
        db: c.make<DatabaseManager>()
      )
    );
    
    // Add subdomain routing
    container.singleton<SubdomainRouter>((c) =>
      SubdomainRouter(
        domains: c.make<DomainRegistry>(),
        router: c.make<Router>()
      )
    );
  }
}
```

### 5. Process and Queue Integration
```dart
// Process package integrates with Queue for background tasks
class ProcessManager {
  // Current Integration
  Future<void> runProcess(String command) async {
    var process = await Process.start(command);
    queue.push(ProcessMonitorJob(process.pid));
  }
  
  // Laravel-Compatible Enhancement
  Future<void> runProcess(String command) async {
    // Add scheduling
    scheduler.job(ProcessJob(command))
      .everyFiveMinutes()
      .withoutOverlapping()
      .onFailure((e) => notifyAdmin(e));
      
    // Add process pools
    processPool.job(command)
      .onServers(['worker-1', 'worker-2'])
      .dispatch();
  }
}
```

### 6. Model and Event Integration
```dart
// Model package integrates with Events for model events
class ModelEventDispatcher {
  // Current Integration
  Future<void> save(Model model) async {
    await events.dispatch(ModelSaving(model));
    await db.save(model);
    await events.dispatch(ModelSaved(model));
  }
  
  // Laravel-Compatible Enhancement
  Future<void> save(Model model) async {
    // Add transaction awareness
    await db.transaction((tx) async {
      await events.dispatch(ModelSaving(model));
      await tx.save(model);
      
      // Queue after commit
      events.afterCommit(() =>
        events.dispatch(ModelSaved(model))
      );
    });
  }
}
```

## Package-Specific Integration Points

### 1. Container Package
```dart
// Integration with other packages
class Container {
  // Current
  void bootstrap() {
    registerSingleton<EventDispatcher>();
    registerSingleton<QueueManager>();
    registerSingleton<CommandBus>();
  }
  
  // Enhanced
  void bootstrap() {
    // Add service repository
    registerSingleton<ServiceRepository>((c) =>
      ServiceRepository([
        EventServiceProvider(),
        QueueServiceProvider(),
        BusServiceProvider()
      ])
    );
    
    // Add deferred loading
    registerDeferred<ReportGenerator>((c) =>
      ReportGenerator(c.make<Database>())
    );
  }
}
```

### 2. Events Package
```dart
// Integration with other packages
class EventDispatcher {
  // Current
  Future<void> dispatch(Event event) async {
    if (event is QueuedEvent) {
      await queue.push(event);
    } else {
      await notifyListeners(event);
    }
  }
  
  // Enhanced
  Future<void> dispatch(Event event) async {
    // Add broadcast channels
    if (event is BroadcastEvent) {
      await broadcast.to(event.channels)
        .with(['queue' => queue.connection()])
        .send(event);
    }
    
    // Add event subscribers
    await container.make<EventSubscriberRegistry>()
      .dispatch(event);
  }
}
```

### 3. Queue Package
```dart
// Integration with other packages
class QueueManager {
  // Current
  Future<void> process() async {
    while (true) {
      var job = await queue.pop();
      await job.handle();
    }
  }
  
  // Enhanced
  Future<void> process() async {
    // Add worker management
    worker.supervise((worker) {
      worker.process('default')
        .throughMiddleware([
          RateLimited::class,
          PreventOverlapping::class
        ])
        .withEvents(events);
    });
  }
}
```
