Month: 2025-09 focused on data integrity and test reliability in mautic/mautic. Key outcomes include: (1) Data integrity fix ensuring leads.company is cleared when a company is deleted, via a private clearCompanyInLeadsCompanyFields method and a functional test; (2) CI and test stability improvements for ListController with CI workflow fixes and flaky-test remediation, including updating expectations and replacing isPublished(false) with setIsPublished(false); (3) Strengthened test coverage around lead list behavior and segment-related UI indicators for more reliable deployments. These changes reduce orphaned references, improve feedback cycles, and support safer, faster releases.
