January 2025 highlights for alliance-genome/agr_curation focused on delivering user-facing clarity, strengthening data integrity, and improving performance. Key features include: (1) UI improvements for External Identifier labeling by standardizing to 'Primary External ID' across the UI and displaying MOD release versions for data loads (including AGM associations); (2) internal consolidation of validation logic and data provider handling to standardize cross-references across annotation types, with caching and lazy loading to improve data access. Major bug fix: corrected Xref persistence to ensure validated cross-references are reliably added from xref responses, preserving data integrity. Accompanying improvements include caching of ontology and vocabulary terms, initialization hardening, and test/data consistency enhancements. Value delivered: clearer, more trustworthy data representations, faster load/display of data, and safer, more scalable validation workflows, enabling more reliable releases and data-driven decisions. Technologies/skills demonstrated include frontend UI changes, data modeling and validation, caching and lazy loading strategies, test-driven improvements, and code hygiene (checkstyle) and migration alignment in production hotfix contexts.
