Seven regions, three namesmeasured · Three circles found in the PDF with every overlap present, and each set name placed by its circle.✓ pass✓ pass

Ground truth: Short black is espresso only, flat white espresso and milk, iced long black espresso and cold, iced latte all three, babyccino milk only, milkshake milk and cold, cold brew cold only, and pour-over outside every circle. The circles and words are read back out of the compiled PDF, each word has to be centred in its own region, and no letter may touch a circle's outline, with the line's width counted. Every model on this task.

Pruned shrub
check · how it is decidedrun 1run 2
Reads as a shrubby eye · Pass if it reads as one plant with branches coming off stems, without being told what it is. A tangle, a lattice or loops fail it.✗ fail✗ fail
Flat side from the rulesby eye · Pass if one side ends on a straight line that the rules themselves put there. A box drawn around the plant to cut it fails it.✗ fail✗ fail
Sensible sizeby eye · Pass if the branches can still be followed by eye. So many segments that they merge into a mass fails it.✗ fail✗ fail

Ground truth: The JSON expanded and drawn with turtle graphics offline, and the drawing judged by eye. There is no single right L-system, so nothing here is measured. Every model on this task.
