If some process changes just one byte (or one word) back and forth
then the possibility of this is 25%. Whether such a process can
exist, I don't know... I could not imagine that anyone would want
to change the file when we add it to the repository. In any case,
it is wrong to call it a _paranoic_ mode if there is even a small
(but practically feasable) chance of this to happen.
