    public function addRoute(string $method, string $path, $handler, array $options = []): object
    {
        // Your implementation
        return $this; // Enables fluent interface

    }
}
```

**`JobQueueInterface`** - Interface for job queue implementations with support for scheduling, retries, and job processing.

```
use Solo\Contracts\JobQueue\JobQueueInterface;

class DatabaseJobQueue implements JobQueueInterface
{
    public function push(JobInterface $job, ?string $type = null, ?DateTimeImmutable $scheduledAt = null, ?DateTimeImmutable $expiresAt = null): int
    {
        // Add job to queue
    }

    // Implement other methods: addJob, getPendingJobs, processJobs, markCompleted, markFailed
}
```

use Solo\Contracts\Validator\ValidatorInterface;

class MyValidator implements ValidatorInterface
