What determines the frequency of the new combat service beacon missions? Is it Quanta AI, virtual AI, or probability volume encounters?

It's Quanta. So it's Quanta that goes through and basically says, 'Okay, hey, in this area, we're going to spawn this many,' and then of varying skill levels or varying threat levels. And then from there, the servers pick them up. But it is Quanta in the background saying spawn here, spawn there.
