A deep dive into how Laravel's route binding pipeline works internally. Covers the full lifecycle from raw URI segment to resolved model: the SubstituteBindings middleware, explicit vs implicit binding, how Eloquent's resolveRouteBinding() executes queries, scoped child bindings via parent relationships, soft-delete support with withTrashed(), backed enum resolution, and three customization extension points (Route::model(), Route::bind(), overriding resolveRouteBinding()). Includes a step-by-step walkthrough of a nested scoped binding request and practical tips for real applications.
