Code Review

This pull request addresses a flaky test by relaxing a strict assertion. The test now correctly validates that either the model's output reflects the requested persona or the reasoning behind the output acknowledges it. This is a more robust approach for testing language models, which can be non-deterministic. The implementation is clean, and the improved assertion message will aid in debugging future test failures. The change is sound and I have no concerns.
