LLM session transcripts as part of the commit is a neat idea to consider, to be sure, but I know that I damn well don't want to read eight pages of "You're absolutely right! It's not a foo. It's a bar" slop (for each commit no less!) when I'm trying to find someone to git blame.

The solution is as it always has been: the commit message is where you convey to your fellow humans, succinctly and clearly, why you made the commit.

I like the idea of committing the initial transcript somewhere in the docs/ directory or something. I'll very likely start doing this in my side projects.
