Compare two vintages of the same dataset and report where each column drifted. Covers columns added, removed and reordered, null-rate movement beyond a tolerance, a dominant type that changed, cardinality that moved, and a range that widened - which means values outside what anything downstream was built for, whatever the distribution looks like.
