Consider a production Laravel application that needs to use Private files. 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 private files 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: Sensitive documents should normally be stored on private disks with controlled download responses. A useful implementation pattern is: $request->validate([ 'document' => ['required', 'file', 'max:5120'], ]); $path = $request->file('document') ->store('documents');
