Interview Prompt
A daily revenue pipeline runs from a cron entry on a developer's laptop: bash dumps a CSV, scp moves it, a Python script loads Snowflake, then emails a Looker URL. When the laptop sleeps the pipeline silently fails; SSH timeouts overwrite the previous good CSV; there are no retries or dependency tracking. Apply the section's DAG framing and convert this to a real orchestrated pipeline.
