Most devs ship whatever the AI writes.
Prove you don't.

Four short snippets, drawn from Python, TypeScript, JavaScript, Go, SQL and Java. You won't get all six — and you don't need to write them all. Some hide real bugs, some are clean. Flag what's broken before the clock runs out — or they ship with your name on the commit.
