When Quality Becomes Quantity — Goodhart's Law and the Metrics Trap. "When a measure becomes a target, it ceases to be a good measure."[1] This is the missing chapter of your Cucumber polemic.

You already hint at this in Five Essential Lessons when you say "automation is a tool, not a goal"; Goodhart lets you prove it.
