Three Messages

Anyone can steer a model with unlimited turns. The skill shows up when you have three: what you say first, what you check, and when you stop steering and read the code yourself. The tests you are graded against stay hidden until you finish.

Get a model to write useDebouncedValue in three messages. The hidden suite checks the first render, the burst, and the unmount — the three moments a quick request never mentions.
