1202-1279: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAdd callback-based
getApiCredentials(...)coverage for both final outcomes.The changed tests cover
awaitApiCredentials(...)and callback-basedgetCredentials(...), but not callback-basedgetApiCredentials(...). Existing callback API-credentials tests invokeonAuthenticationSucceeded(true)directly, so they do not exercise the unrecognized-then-final-result sequence. Add success and lockout cases for the separatecontinueGetApiCredentials(...)path.Suggested fix
