Temporary Autonomous Zoners, yes you!

[Tinitus]

1. But is this premise permanent or not

No. It is limited to the time of existence of the universe.

2. Does it become temporary, if say, the permanency permeates the temporary confines of its non-existence, thereby becoming permanent if only for a fraction of a temporary permanence?

No. Something that happens for a limited amount of time is not permanent.
