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.
