Consider a production Laravel application that needs to use Custom value transformation. How should the developer approach the requirement, and what should be checked before releasing it? Assume the system receives real users, real data and concurrent requests. The correct approach is to identify where custom value transformation belongs, define its inputs and outputs, protect the boundary with validation and authorization where applicable, consider database and performance implications, and add automated tests for the expected behavior. Concept-specific reasoning: Custom casts can encapsulate more specialized conversion rules when built-in casts are insufficient. A useful implementation pattern is: protected function casts(): array { return [ 'is_active' => 'boolean', 'settings' => 'array', ]; }
