March 2026: Delivered a robust enhancement to the Report Selection Filter in ministryofjustice/bichard7-next-core. Implemented comprehensive validation for date ranges and dropdown selections, improved user feedback with clear error messages, and refactored date handling using date-fns to improve reliability and maintainability. Changes included moving date range inputs into a dedicated component, refining min/max date logic, and updating tests to cover validation scenarios and edge cases (including API call checks and validation message constants). Result: fewer invalid report runs, improved user experience, and a cleaner, more maintainable codebase. This work is captured in commit 1c9cde0b1f64c744a1c2481c8f5c541c6358ea1c with co-authors irenegrandeh and Richard Race.
