summary

Builds a tiny coffee machine app commit by commit, measures method complexity with flog, and watches scores climb from ~5.5 to 25.5 as conditionals and optional ingredients accumulate. Reintroduces duplication by rehydration to surface missing abstractions, extracts polymorphic beverage classes, adds a factory and null object, and drops complexity back into the “awesome” range so adding soup requires no edits. Ends with a churn vs complexity workflow to find hot spots.
