From the book:
Hmm.. seems like every snapshot in the timeline you can find where the safe is open, it’s also mostly cleared out in that moment? That’s some impressive version control discipline.
It certainly seems, from the way you put it, that it's possible to scrub the archives without using Authority, or at least prevent something from being recorded. Can the players make use of this? Perhaps erase evidence of opening the door, or ensuring the timeline doesn't have a snapshot of someone stealing a memory?
