the prompt it was given

In this knitting chart of a cup cosy with a coffee-bean motif, the bean comes out 2.4 times as long as it is wide once the fabric is knitted, where it should be between 1.3 and 1.8 times. Change the bean so it knits true. The stitches are drawn wider than the rows, so the motif needs rows added or stitches taken away. Change nothing else: the grid, the cell size, the key and the rest of the chart stay as they are.

Frozen at v1. This model got this and nothing else.

ground truth

DeepSeek 4.1 Flash drew this chart on 2026-10-19. Its bean is 13 stitches by 8 rows in cells drawn 20 by 14.3, with a gauge of 1.399 stitches to the row, so the knitted bean comes out 2.43 times as long as it is wide against a band of 1.3 to 1.8. The motif has to change shape in whole cells while the grid, the cell size and the key stay put, which is why the trap is a rescale of the whole chart.
