I'm talking about programs that can't be improved no matter what. They do exactly what they're supposed to and will never be changed.

It'll probably have to be something small, like cd or pwd, but does such a program exist?

The flight software for the Apollo moonshots.

It was fault tolerant but I wouldn't say it was perfect. There were plenty of "known issues", and the fix in production was basically, "don't do that".

It's on Github and has several PRs.
