This is an ad-hoc example and not a real test case.
--8<---------------cut here---------------start------------->8---
$ echo "foo" > ~/.cache/guix/inferiors/last-expiry-cleanup
$ cat ~/.cache/guix/inferiors/last-expiry-cleanup
foo
$ ./pre-inst-env guix time-machine --commit=9d795fb -- help
Usage: guix OPTION | COMMAND ARGS...
Run COMMAND with ARGS, if given.
--8<---------------cut here---------------end--------------->8---
As previously mentioned, the patch fixes:
- empty file
- non-integer
I am not able to imagine an incomplete file worse than \\x00.

I do not understand what you mean and I think you are overengineering.
If you are able to produce a corrupted file which breaks "guix
time-machine", then we can examine. Else let move on. :-)
Cheers,
