PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Typo in Command The example command for running tests with JUnit XML output appears to have a duplicated uv run nox -s test -- segment. This should be corrected to ensure the command is valid and functions as intended. uv run nox -s test -- uv run nox -s test -- --cov_report=xml
