First Contact

A small TypeScript cart library. CI is red: one test in src/cart.test.ts fails. You have never seen this code. Get to a green test run — without opening a file yourself.

Nothing here calls a model or touches a repo. The scenario is a state machine, so the same sequence of instructions always ends in the same place — which is what makes the feedback afterwards a fact rather than an opinion. You start 5,280 tokens down before typing a word; that is what a real session costs at launch.
