January 2026: Focused on strengthening regression test coverage for time-series indexing edge cases in pandas-dev/pandas. Delivered two targeted regression tests addressing known issues with MultiIndex timeIndex sorting and NaT masking alignment, improving reliability for time-series workflows and reducing regression risk in core indexing paths. These tests lay groundwork for more robust time-based indexing and demonstrate a disciplined test-driven approach to bug regression prevention.
