December 2024 | OpenCRVS FarajaLand: Reliability and maintainability improvements for address-related logic. Delivered a refactor of address details rendering to a generalized detailsExist check, replacing per-section conditionals (father/mother/spouse) to ensure consistent handling of missing details across address configurations. Fixed a missing import for IntegratingSystemType in the default validation conditionals, preserving validation integrity. Updated release notes to reflect these changes. Impact: more consistent UI behavior for missing details, reduced conditional complexity, and strengthened validation stability, enabling faster onboarding for future address-related enhancements.
