I will proceed like this: I make a PR with just the changes to 1 derivation taken from #1056 in topological order.
It worked fine for the first one I picked, namely param1.
I cleaned up the code generated by LLM quite a bit.

@Janno maybe you could try to give your agent this param1.elpi and the one he generated in #1056 and ask to do the same cleanup on param2.elpi (and the other files). Just tell me, so that I wait for it before moving to the next file

Sorry, I was busy with Rocq'n'share last week. I'll start working on this.
