StopIron Law: no production code without a failing test. Never skip red-green-refactor.

Steps

[ ] Every new function/method has a test
[ ] Watched each test fail before implementing
[ ] Each test failed for expected reason (feature missing, not typo)
[ ] Wrote minimal code to pass each test
[ ] All tests pass
[ ] Output pristine (no errors, warnings)
[ ] Tests use real code (mocks only if unavoidable)
[ ] Edge cases and errors covered
