Loadingone moment…
A waste-collection depot. Every night the trucks report which bins they serviced; every morning supervisors need the list of bins that were scheduled and missed. The schedule itself lives in a spreadsheet a depot supervisor edits by hand, and it is the only place that knows which bins are on which round.
A cadence chosen by the thing that reads the output, not by habit.

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.
