You wrote all your tests. You hit 100% coverage. You deployed with confidence. Then some user types "🎉" in the name field and your entire database implodes because nobody thought to test what happens when someone treats form validation like a suggestion. 100% test coverage just means you tested 100% of the scenarios you could imagine—not the ones users will definitely try. Your tests passed. Your app didn't.
