Pristine

Pristine

<priss-teen>

new; untouched; unused;

something in its original state.

The paper was pristine because she could not think of a thing to write.

Memory trick:
pristine reminds of pri or prior

At work:
I undid the changes and the program is pristine again. We can add the changes again until we find the problem.
