- Line 51: Update the findRoutedMiddleware generation to conditionally wrap
serialized middleware handlers with wrapHandlerWithTracing when traceH3 is
enabled, matching the route-handler path while preserving the existing behavior
when tracing is disabled. Add the corresponding trace-enabled template
assertion.

The test name claims
route-rules -> global -> routedorder, but Line 112 checks onlyglobal, routed. The test can pass if route-rule middleware runs at a different position. Add a route-rule order marker and assert the complete sequence.🤖 Prompt for AI Agents

- Line 100: Update the routed middleware handling in findRoutedMiddleware to use
a middleware-specific tracing wrapper that emits type "middleware" instead of
the route-oriented wrapHandlerWithTracing behavior, while preserving the
existing tracingChannel.h3 guard and handler wrapping flow.

Resolves #4557
❓ Type of change
📚 Description
When registering route-scoped middleware (
middleware: trueon route patterns),findRoutedMiddlewarepreviously serialized entries usingserializeHandler, which produced{ route, method, meta, handler }descriptor objects. The generatedapp.tspasses the matching data directly toh3as middleware (middleware.push(...findRoutedMiddleware(...).map(r => r.data))), causingTypeError: fn is not a functionduring request handling.This fix updates
findRoutedMiddlewareinsrc/build/virtual/routing.tsto serialize entries usingserializeHandlerFn(matching global middleware behavior), ensuring callable handler functions are emitted. Added unit test and integration test verifying route-scoped middleware execution.📝 Checklist
