Labs that let you break a rule before you trust it
Boundary, State and Stress-Test labs have you predict, run and compare a rule on small cases, right in the lesson.
A Boundary Lab runs a rule across its edge cases so you see exactly where it changes. A State Lab lets you predict, act, inspect and undo on a small model of where things are. A Stress-Test Lab puts a stated contract against small tables built to break it.
Each one asks for your prediction first, then shows what really happens, and your Maestro can talk through any surprise.
