+        This is a defensive test documenting expected security behavior for CLOSED accounts.
+

+        Expected behavior: CLOSED accounts should be rejected like BANNED accounts.
+
+        Context:
+        - AccountStatus.CLOSED is defined in the enum but never used in production
+        - The close_account() method exists but is never called
+        - Account deletion uses external service instead of status change
+        - All authentication services (OAuth, password, email) don't check CLOSED status
+
+        TODO: If CLOSED status is implemented in the future:
+        1. Update OAuth callback to check for CLOSED status
+        2. Add similar checks to all authentication services for consistency
+        3. Update this test to verify the rejection behavior
