What occurs if no objects are available to be shuffled into a library?

When there are no objects to be shuffled into a library, a shuffle still cannot occur. In fact, the appropriate resolution under the rules is that the library remains unchanged. This is consistent with the understanding of shuffling in Magic: The Gathering, where shuffling requires at least one object to participate in the process. Therefore, if there are no objects available, the library remains the same as before; nothing is added or altered.

The shuffling mechanics in Magic specifically state that the act of shuffling necessitates the actual participation of cards or objects to shuffle, indicating that the absence of such objects precludes any shuffling action from taking place. Thus, the correct conclusion is that if no objects are available to be shuffled into a library, the library remains unchanged as no shuffle occurs.
