Nothing in this lesson asked you to write a line of application code — every earlier lesson in this track did that, and that's exactly what let you skip straight to directing here. The skill this capstone actually tested is the one every lab in this track drilled into you one command at a time: never settle for "it ran" — verify it's right. A recipe site is small enough to hold that judgment call in your head all at once. The next lesson hands you the version where getting it wrong costs someone a real appointment.
