 - Use `.execute.bind(instance)` for direct method calls
 - Generate static middleware array when all middlewares are singletons
 - Replaced `...arguments` with explicit `(req, res, next)` parameters
+- Use pre-compiled resolvers (`injector.getResolver()`) for request-scoped middlewares
 
-**Impact:** Significant performance improvement for applications with many singleton middlewares.
+**Impact:** Significant performance improvement for applications with many middlewares.
 
 **Files:**
 - `packages/http/src/router.ts` - Middleware optimization logic added
 - `packages/http/src/http.ts` - Simplified middleware execution
 
+### 5. Improved Error Logging (DX)
+
+**Problem:** Middleware errors logged generic messages like "Could not resolve request" without context.
+
+**Solution:**
+- Log middleware name (class name or function name)
+- Include HTTP method and URL in error messages
+- Use named functions in generated code for better stack traces
+
+**Impact:** Much easier debugging when middleware fails.
+
+**Example output:**
+```
+Middleware AuthMiddleware threw on GET /api/users: Invalid token
+```
+
+**Files:**
+- `packages/http/src/http.ts` - Contextual error logging
+- `packages/http/src/router.ts` - Named function generation
