Feb 1, 2026February 2026 – sul-dlss/hungry-hungry-hippo: Key features delivered, major bug fixes, overall impact, and technologies demonstrated. Key features delivered: - GitHub integration lifecycle: Consolidated changes, added GitHub fields to the user model, improved validation messaging for repository checks, and removal of the GitHub integration feature to reduce maintenance risk. - Deposits UI enhancements: Added a Deposit Status column and reorganized deposits table for clarity. - Depositor search usability: Added instructional text to guide users on how to enter druids for the depositor search. - Crossref metadata sanitization: Stripped HTML and XML tags from metadata fields to improve data cleanliness. - License selection UI overhaul: Replaced article license component with a works license component and introduced new parameters to streamline license handling. Major bugs fixed: - Breadcrumbs title display: Breadcrumb-derived page titles no longer render HTML entities, improving display and usability. - FK constraint handling for deletions: Grouped fixes to prevent constraint errors when deleting related records. - Depositor notification clarity: Enhanced notification text and alert rendering to reflect deposit status more clearly; updated tests accordingly. Overall impact and accomplishments: - Strengthened data integrity, user experience, and deposit workflow reliability across the app. Reduced maintenance surface by removing deprecated integration paths and improved testing coverage for deposit-related processes. Technologies/skills demonstrated: - Ruby on Rails, ActiveRecord constraint handling, SQL-level fixes, data sanitization, test-driven development (RSpec), UI/UX refinements, email workflow updates, and component-based license handling.

Aug 1, 2025August 2025: Stability improvement in hungry-hungry-hippo via standardized Faraday connection error handling in RorService and proper error propagation during API calls. Implemented through two commits converting custom connection failures to StandardError and removing unnecessary exceptions to let Faraday::Error surface. Result: clearer errors, faster debugging, and more reliable external API interactions.
