A ride-hailing company loads completed trips nightly and reports them by city. Finance compares the warehouse against the app’s own dashboard and the warehouse is consistently short — by about 0.01%. No job has ever failed, no error has ever been logged, and every number in the report is correct.

Run the review to check your architecture against this scenario — a valid DAG, a trigger for the freshness SLA, a transform stage, a quality gate before publish, and a failure path — then defend it in a short interview.
This scenario runs a full workspace — editor, canvas and results side by side. It needs a laptop or desktop to be usable. Open this page on a bigger screen to start building.
