the prompt it was given
Make an SVG knitting chart for a cup cosy with a coffee-bean motif, drawn so the beans come out the right shape in the finished fabric.
Frozen at v1. This model got this and nothing else.
ground truth

A knit stitch is wider than it is tall, about 5 stitches to 7 rows over the same distance, so a bean drawn on square cells knits up squashed. The chart is read from the SVG: its grid, which cells are coloured, and the gauge its cells are drawn at. Each bean is then measured as it would come out in the fabric, from its stitches and rows at that gauge, and a coffee bean is 1.3 to 1.8 times as long as it is wide. How it is scored, and this run's files on GitHub.
