@ahoppen I'm not sure if the new generated files is a mis in a previous PR?

But can we, some how, avoid missing code generation in the future?
You mentioned the Ci don't have access to the internet.

But can we, in the CI refer to a local swift-syntax package?
I think the builder is now, OK stable?

Oh, I think that was my fault. I probably forgot to re-generate the files in one of my previous PRs.

Hmm, an interesting idea could be if CodeGeneration would refer to HEAD instead of a fixed commit of the parent repository. That way you can work locally and basically have a stable base for your CodeGeneration changes, i.e. changes you make in your working copy don’t immediately impact whether CodeGeneration compiles. And only after you commit do you need to adjust CodeGeneration. That could work.
