In CodeBuilder, validation for a slot was missing due to concurrent patches, and the original patch did not add effective tests for CodeBuilder because of the complex exceptional behaviors. Now the bug is fixed with renames to prevent future risky usages, and the tests have been enhanced to ensure at least the failure-case behavior (while the non-failure case is harder to check due to exceptional behaviors)
