a cube is first its shape: the columns every piece has. a table called violations has rows, each one a violation, and its first column is what a violation is pointed to by (its one line, its title), before anything else is known about it. opening the cube on its rows skips the shape and puts the pieces where their faces should be; adding a kind beside them then mixes a thing with a way of looking at things, and principle 16 seems to break ("apps has no app"). it does not break: the face shows a violation's shape (examples, apps, what happened to it, the principles it breaks, seen, pictures, why it feels wrong, how it could follow), and every violation has all of them, pale where nothing is known. the name of the cube (violations) and the name of its pieces (a violation) are the same word, which is where the confusion comes from; the first column needs a word of its own, and here it is examples.
