Tracy McCormick focused on backend development for the samvera/hyku repository, addressing a bug affecting multi-tenant search metadata handling. Tracy implemented a safe fallback mechanism for search-only tenants, ensuring they relied on the basic available_works configuration rather than attempting to access flexible schema details, which previously caused errors. This solution improved the reliability of search results across different tenant configurations. Tracy also wrote targeted tests for the filtered_available_works method to validate the fix and maintain correct tenant-specific search behavior. The work was delivered as a targeted patch using Ruby and Ruby on Rails, with an emphasis on robust testing practices.
