The Data Path

Every video here was transcript-vetted before it earned a place. Clips start and stop on the exact segment, so press play and trust the cut. Tick things off as you go; progress is saved in this browser.

After the videos: the profiling exercise on a real client sheet, then we build /data-audit together. And Kimball chapters 1 to 3 plus 7 for the two things no video teaches (grain canon, additivity).
