Dec 1, 2025December 2025: Delivered critical enhancements and bug fixes for the companieshouse/test-data-generator repository. Key features include partial payments for penalties (added field for part payment and updated outstanding calculations) with corresponding tests and documentation updates. Dunning workflow improvements for penalties: added a default value, validation pattern, and expanded the enum with additional statuses PEN2 and PEN3. A fix was implemented to prevent duplicates in penalty specifications for AccountPenalties, supported by added unit tests. These changes enhance financial accuracy, prevent data inconsistencies, and strengthen test coverage, contributing to more reliable penalty processing and better compliance.
