October 2025 focused on delivering a robust Run Classification Management feature for DEFRA/epr-calculator-frontend, along with a fix to the back button navigation. The Run Classification Management enables classification of calculation runs as Test Run or Delete, with refactored business logic, new controller actions, constants, and accompanying unit tests, plus UI updates to support the new workflow. A back button navigation bug was fixed by removing a hardcoded link to the RunANewCalculation controller to prevent navigation to an incorrect page. The work improved data integrity, user experience, and maintainability.

In September 2025, reliability, data visibility, and user experience were the primary focus across the DEFRA epr-calculator repositories. Key features delivered: - API: Correct Run Completion Status Mapping implemented with unit tests covering valid and invalid initial classifications to ensure accurate completion state and graceful error handling. Commit 0030f1ed262abaeab0685841627b0e82f6f7deac. - Frontend: Classification Dates Screen added to the EPR Calculator, displaying status and completion dates (initial, interim, final) with UI enhancements; includes controller refactor and helper methods. Commit 9f0b6ea6a64948866a444efcae8067cc493e0f5f. - Frontend: Completed Runs Page Back Link & Session Navigation improved with a conditional back link and enhanced user info/sign-out flow. Commit 1be10e3bf208917e7e8ce64eaeacfe5cb70e6b02. Major bugs fixed: - API behavior corrected to map CalculatorRunClassificationId to the completed state upon run completion, with added unit tests to verify handling of edge cases and improve error resilience. Overall impact and accomplishments: - Improved data accuracy for run completion, reducing misreporting risk and downstream decision impact. - Enhanced visibility of run classifications through a dedicated dates screen, improving decision making and stakeholder trust. - Smoother navigation and session management in the frontend, contributing to better user productivity and fewer navigation-related issues. Technologies/skills demonstrated: - API reliability and test-driven development (unit tests for edge cases). - Frontend architecture improvements (controller refactor, helper methods) and UX enhancements. - Navigation and session management improvements, contributing to a more robust user experience. - Clear traceability through commit-level documentation and aligned feature delivery. Business value: - Fewer support tickets related to run state mapping. - Faster, more intuitive access to classification data for operators and analysts. - Reduced risk of workflow disruption due to navigation and session issues.

July 2025: DEFRA/epr-payment-facade delivered OrganisationId support for the Offline Payment API (v2) with validation and test coverage. This work strengthens data integrity, enables per-organisation accounting/governance, and lays groundwork for organisation-scoped processing.
