Below is a clean implementation demonstrating service encapsulation with dependency injection:

<?php

use App\Models\User;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Log;

class TechnicalArchitectureService
{
    /**
     * Execute optimized domain logic with transaction safety
     */
    public function processBatch(array $payload): bool
    {
        return DB::transaction(function () use ($payload) {
            // Process business logic cleanly
            Log::info('Processing optimized payload', ['count' => count($payload)]);
            return true;
        });
    }
}

3. Key Takeaways & Best Practices

• Keep controllers thin by delegating complex business workflows to dedicated domain action classes or services.
