Come on in! Making yourself at home in a new codebase
summary
Contribution targets rubygems.org and a single “good first issue” drive the work: reproduce a bug where adding an owner sometimes silently fails, trace creation paths via git history and controller/model call stacks, and learn by interactive debugging in the Rails console. Fix wraps the create flow in an ActiveRecord transaction and raises ActiveRecord::Rollback on failure so the database never leaves partial state. Tests reveal the original silent-success behavior; PRs update an out-of-date ERD and close the stale issue.
