Pushed the first version of the last feature I want to add in 2022, relevance visualization in the fact editor. You fill in what you know. If you don't know, or there might be more values, you "unlock" that category or attribute. Run the test. It shows you the answers it finds, and any assumptions it used to find them. (e.g. bob won if jane threw scissors.) Any inputs relevant for finding new unconditional answers (e.g. what jane threw) are highlighted in green.
