Loadingone moment…
A freight brokerage. Loads land from the dispatch system every fifteen minutes; carriers come from a compliance vendor in one extract a night. A load booked at 14:00 can name a carrier approved at 13:40 — one the warehouse will not see until 02:00. Today those loads are silently dropped: 0.4% of them, disproportionately the newest carriers, and nothing has ever failed.
The schedule for each side — and the fact that you control one of them and not the other.

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.
