Getting a Handle on Legacy Code
summary
Starts with the Gilded Rose kata, adds support for conjured items that must degrade quality twice as fast, and proves it with focused specs plus Golden‑Master checks using the approvals gem. Uses SimpleCov to drive tests to 100% line coverage briefly, runs flog to show complexity falling (update_quality ~155 → ~45), extracts methods (update_item, increase/decrease_quality), and commits baby‑step refactors. The feature is implemented and tests pass, leaving the code measurably cleaner and the behavior verified.
