What is Scope composition in Laravel, and what role does it play in a real application? In Laravel, scope composition should be understood as part of a larger application architecture rather than as an isolated API call. Multiple scopes can be chained together to express readable business filters. A strong understanding includes its purpose, the layer where it belongs, the data or request flow it affects, and the situations where another mechanism may be more appropriate. Practical context: Local and reusable query scopes let a model define common filtering rules in a consistent, composable way. The specific focus here is scope composition: Multiple scopes can be chained together to express readable business filters. This question is designed to test not only terminology, but also how the concept fits into Laravel's request, application, database, security, or deployment workflow.
