Oct 1, 2024

October 2024 achievements focused on stabilizing user-facing UX and accelerating data-management workflows across gateway-web and gateway-api. Key navigation and branding issues on the Our Mission and Purpose page were resolved, restoring correct banner rendering and consistent labeling. In the API domain, we delivered multiple tooling improvements: a robust CSV-driven migration tool to assign teams to collections with data integrity checks, unassigned fallbacks, and user-visible progress; a CSV-driven image-link updater with dry-run previews and enhanced logging; and lifecycle improvements including soft deletes for DatasetVersionHasNamedEntities. We also strengthened safety around collection deletion with per-user access checks and added tests to guard against regressions. These efforts reduce manual remediation, improve data integrity, and accelerate content/collection management while maintaining strong auditability and developer velocity.
