What issue are you seeing?

The run drifted from bounded readability refactoring into a cross-language style rewrite inside Python test code, producing repository mutations that were syntactically invalid and not recovery-safe.

What steps can reproduce the bug?

1. Open a repository-backed workspace.
2. Ask Codex CLI to perform the requested edit, repair, or cleanup workflow reflected by this report.
3. Observe whether it reproduces the failure described above.

What is the expected behavior?

Codex CLI should either apply a valid change or fail cleanly. It should not corrupt repository state, write invalid syntax, or perform over-broad filesystem actions.
