Minor cleanups (CodeRabbit-flagged misplaced section comments): - auth_test.go:268-272: section header "Unit tests — AuthenticatorFunc adapter" was embedded inside an if-block; lifted to between the two test functions. - auth_test.go:1438-1443: section header "Integration tests — httptest + gorilla/websocket Dial" was embedded inside a t.Errorf argument list; lifted to between the test function and the helper. - redis_test.go:349-353: section header "PublishBroadcast — messages reach local WebSocket clients" was embedded inside an if-block; lifted to before the next test function. Pre-existing layout artefacts that survived the testify-removal pass in HEAD; surfaced by CodeRabbit on the dev→main PR.
