Summary
- Throwaway code that answers a single design or logic question through an interactive prototype.
- Choose between two branches: a terminal app for testing state machines and business logic, or multiple toggleable UI variations on a single route for design exploration Minimal setup with one command to run; state lives in memory with no persistence unless the question explicitly requires it Surface full state after every action so changes are immediately visible and the prototype's answer is clear Delete or fold validated decisions back into production code once the question is answered; capture the verdict before cleanup
