Non-triviality

The engine's own test of worth: an experiment that could be conceived from a review article alone fails it.

An experiment must require knowing the specific chain from goal to pillar to requirement to science to gap to hypothesis that produced it. Non-triviality is the highest-priority criterion of the best-experiments selector. The engine has no separate "novelty" field; the nearest words are this test and the operator's "not novel" feedback category.
