LEVEL 1 IS MARKET MAKER. THE TUTORIAL ROUND IS THE MARKET FORCES LAB.
Level 1 asks whether you know the idea. This one asks whether you can use it on something messy. Every round is a brief drawn from what is actually happening right now — model pricing, export controls, a reunion tour, a grid under strain — and three linked steps that build on each other. You also stake how sure you are before each answer, which turns out to be the hardest part.
Briefs rotate: the engine prefers cases you have not seen recently, so a second run is genuinely different material.
Being well calibrated means your High stakes land far more often than your Low ones. If they do not, the problem is not the economics — it is that you cannot yet tell which of your answers to trust, and that is worth knowing.
