OK, question.

Seems that this code was largely machine-generated. So I assume that
you're in possession of the scripts/prompts/whatever which were used to
generate this code.

(Can you please briefly describe the process which you used here?)

So how are we to maintain this? Will other developers have to go in
and hack this machine-generated output by hand? Or would it be better
to provide (in-tree) other developers with the means to regenerate this code,
presumably using Claude?

IOW, this feels a bit like shipping the .s file without giving us the .c
file!
