AFAIK we don’t actually know that the Bent Pyramid was a design flaw with a course correction in the middle. We only think that because it’s the only one with a slope that changes in the middle, but there were few pyramids before that one: before the Bent Pyramid was the Meidum one that also had a steep slope, and before that was Djoser’s step pyramid, which was the very first one. And Meidum was a step pyramid too before the sloped casing was added in the last phase. We don’t actually know that they planned for a very tall one then gave up, and what they were experimenting.
Is that the partially collapsed pyramid?
No, it’s a pyramid they sort of fucked up on by putting on an unstable foundation and had to chance the slope of because of it.

To be fair, it was a precursor of the Great Pyramid, so they didn’t really know what they were doing yet.
Ah yes, my visual memory was correct, but the reasoning for the shape was incorrect.
