All five partsdecided by looking · Pass if every listed part is drawn as a separate shape and each has a label naming it. A part only named in a label or a comment, with nothing drawn, fails it. The label must say what the part is, in any words: a name that only says where it sits ("top plate") or what it is made of, or a mention in another part's caption, does not count.pass
Stack orderdecided by a number, from the filepass
Parts fitdecided by looking · Pass if each listed pair of mating parts looks as if it would go together as stated: the right angle, nested inside, or sitting on top. One pair that plainly could not fails it.pass
Two assembly axesdecided by looking · Pass if one line runs through the middle of every part on each listed axis, and every leader line leaves from the same side. One part pushed off its axis fails it.pass
Labels matchdecided by looking · Pass if following each leader line from its label ends on the part that label names. One label pointing at the wrong part, or at nothing, fails it.pass

There is no post about this one, since only some results need one, so the picture, the source and the scoring are here instead.

the prompt it was given
Draw an exploded assembly diagram of an espresso machine portafilter, as an SVG. Use a double-spout portafilter with a removable basket rather than a bottomless one.
Frozen at v1. This model got this and nothing else.
ground truth

On a vertical axis, top to bottom: filter basket, retaining spring, portafilter body, double spout. The handle is on a horizontal axis off the body, so this is the one member with two axes. Checked against parts sellers, since no maker's exploded diagram could be fetched: Espresso Parts and Zirkus Coffee on the spring that clips into a groove inside the body and grips the basket rim, Espresso Parts on the spout that screws onto the bottom of the body, and Nepo Coffee on handles that screw onto a stud on its side. How it is scored, and this run's files on GitHub.
