Problem

A 30-engineer company has one daily Python ETL: it runs on a cron, lands rows in Snowflake, and feeds a Looker BI dashboard. The transform has no orchestrator owning its schedule, no observability watching its output, hardcoded credentials, no catalog, no CI runner, and no cost attribution. Apply the section's six-undercurrents framing and add each one as named tooling around the four roles already on the canvas.
