+//! Laravel [`super::super::FrameworkAdapter`] (Phase 16 — Track L.14).
+//!
+//! Two recognition shapes:
+//!
+//!   - Closure route: `Route::get('/path', function ($payload) {…})`
+//!     declared at top level — the closure's function name is the
+//!     enclosing summary's name (the static-analysis side already
+//!     stamps anonymous closures with a synthetic name slot).
+//!   - Controller-method route:
+//!     `Route::get('/path', 'UserController@show')` /
+//!     `Route::post('/path', [UserController::class, 'save'])` plus
+//!     a `class UserController { public function show($id) {…} }`
+//!     declaration in the same file.
