• [nitpick] Variable name basicDirectResponseManifests is plural but holds a single manifest path. Consider renaming to basicDirectResponseManifest for clarity.

	basicDirectResponseManifests       = filepath.Join(fsutils.MustGetThisDir(), "testdata", "basic-direct-response.yaml")

.github/workflows/pr-kubernetes-tests.yaml:46

• The CI regex now includes DirectResponse but doesn’t include the LoadTesting suite. Add |^TestKgateway$$/^LoadTesting$$ to ensure load tests run in CI.

          go-test-run-regex: '^TestKgateway$$/^DynamicForwardProxy$$|^TestKgateway$$/^Deployer$$|^TestKgateway$$/^RouteDelegation$$|^TestKgateway$$/^Lambda$$|^TestKgateway$$/^AccessLog$$|^TestKgateway$$/^LocalRateLimit$$|^TestKgateway$$/^Cors$$|^TestKgateway$$/^BackendConfigPolicy$$|^TestKgateway$$/^Metrics$$|^TestKgateway$$/^HttpListenerPolicy$$|^TestKgateway$$/^Tracing$$|^TestKgateway$$/^DirectResponse$$'

• The code uses filepath.Join but has no import for "path/filepath". Please add import "path/filepath" to avoid compilation errors.

• The test now asserts RouteReasonUnsupportedValue instead of RouteReasonBackendNotFound. Verify that the plugin’s status reason was intentionally changed and matches implementation.
