Worked on migration and stability improvements across the alphagov/whitehall and alphagov/govuk-e2e-tests repositories, focusing on supporting Content Block Tools v1.14 to enable a smooth transition of pension amount formats. Addressed a package management issue by reverting an unintended multi-package update, restoring repository stability. Updated end-to-end tests using JavaScript and related testing frameworks to reflect changes in the Content Block Manager, specifically the separation of the pension amount prefix from its value. Collaborated with the Content Modelling team to align migration scope and data representation, reducing rework and ensuring data integrity throughout the migration process.
