    This is a decent derivation, if a little verbose, but I find myself doubting the disclaimer at the top:

    If you're writing by hand and trying to avoid accusations of AI-generated content, it's really easy not to write bulleted lists where each item starts with a boldface summary like "A clean bijection in the middle." Or drive home a point with such pithy italicized mottos as "The complexity was never in the map. It was in the basis." If you didn't use AI in the writing here, you have trained yourself very well to write like an LLM.

      So many shibboleths. Zero chance it's not AI.
