Consider a production Laravel application that needs to use Security awareness. 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 security awareness 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: Transformations should not accidentally reveal secrets or bypass authorization when data is serialized. A useful implementation pattern is: protected function fullName(): Attribute { return Attribute::get( fn () => trim($this->first_name . ' ' . $this->last_name) ); }
