Apr 1, 2025April 2025 monthly summary for nttcom/threatconnectome: Delivered reliability improvements to the UserMenu logout flow and AppBar rendering. The logout flow now resets API states, ensures authentication readiness is false, and handles redirects correctly. Removed redundant logout logic from the AppBar, simplifying rendering. Implemented comprehensive unit tests for logout functionality and performed test suite cleanup to maintain stability and readability. These changes improve security, reduce risk of stale authentication states, and enhance user experience during sign-out.
