All the Little Things
summary
Code starts as a 43-line conditional around Gilded Rose and a tick method that Flogs 45 and the class Flogs 50; tests guide refactoring into seams, then many small steps that briefly raise complexity but let tests stay green. The code becomes an item factory (Gilded Rose module), four item classes with tick, and a config hash; Backstage Flogs ~12 and average class Flog ~7, a ~75% complexity drop. seams and characterization tests make Conjured trivial to add and small, focused objects replace the sprawling ifs.
