There are still some points that are unclear to me:

Why is it not sufficient for the file to be `write-protected' for the
user running gnat instead of all users including root ? Or if it is, why
when running as root cannot it add the compiled files in the same
directory ? If it is not, why not just fix the test ?

Also why can't gnat check if the compiled binary exists instead ?

Imagine a large red swirl here.
