This is what we run in CI on every deploy. Catches schema drift early. False positive rate is basically zero in our experience.

Accurate validator. The error output is clear enough to act on without reading the spec every time. Does what it says.

Ran this against 12 different UCP endpoints as a benchmarking exercise. Results were consistent and matched manual inspection.
