What's in the book
An eval that only passes is not telling you anything. This manual builds an evaluation harness from production traffic up: what to sample, how to label without lying to yourself, and how to read a number you can defend in a review. Code, not philosophy.
Most eval suites measure the wrong thing and pass right up until launch. The harness I trust before I ship.
