Cleiviane Costa focused on stabilizing the consent workflow in the power-tools repository by addressing a compatibility issue in the Consent gem. She resolved an ArgumentError triggered by Ruby 3.3’s stricter handling of positional and keyword arguments in scoped methods, refactoring the logic into a class method to ensure smooth operation with Rails 6.1. Her work included expanding the test suite to cover Rails 7.2, which improved regression safety and prepared the codebase for future upgrades. Throughout the process, she applied her expertise in Ruby, YAML, and CI/CD, maintaining cross-version compatibility and reducing upgrade risks for the team.
