契约

• assert route_layer protects routes registered before it, returning 200 with typed Extension and injected headers when authorization token is valid
• assert route_layer rejects unauthorized requests with 401 and custom error headers without invoking the route handler
• assert route_layer leaves public routes registered after it unprotected, returning 200 without executing the auth middleware or incrementing state call counter
• assert an unmatched 404 route on a route_layer router returns 404 Not Found without invoking auth middleware
• assert Router::layer wraps the entire router including 404 fallbacks, returning 401 Unauthorized for unmatched paths when authorization is absent
• assert an unpopulated Extension extractor fails dynamically at runtime with 500 Internal Server Error when the route is not wrapped by the populating middleware
• assert chained layers execute in reverse registration order (bottom-to-top): outer layer runs before inner layer on request, and inner layer runs before outer layer on response
• assert sub-router route_layer middleware is isolated to the nested prefix and does not run on parent router routes
