Are there any examples of 'perfect' software? (sh.itjust.works)

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?

TeX. Best documented source, and last bug found was 12 years ago.

    The 2021 release of Tex included several bug-fixes, so not quite 12 years:

    See also the following list of potential bugs, that may be included in the planned 2029 release of Tex:

    That said, Tex is still an impressive piece of software
