Spontaneous Combustion

You just posted your app, and the internet took you at your word. Big mistake, or the best one, it hit the front page. A thousand people click. Then five thousand. Then 50,000 curious engineers arrive in the same instant, straight into a database you sized for "me and three friends." The waves keep coming after the peak, and when the dust settles you still have steady traffic. Congratulations. Now survive it. The Job: Absorb the entire crowd clean, no drops, latency in the green. Protect the Postgres before it (and your wallet) catches fire.

Free to play, no account needed. A deterministic engine grades your design against this scenario's SLA - error rate, latency, and cost.
