Eugene: LGTM. AI agent: some good suggestions in the comments. I agree with the suggested test changes. Any suggested code changes should be a separate PR. (If you like, I can file an issue for someone else to make the suggested fix.)

Description nit: the prose still says `label21.f90` (the file is `label20.f90`) and shows a stale link.
