From what I recall, the PPP is a research institution that Anne has funded. Dr. Thor, the person who developed A-10 and the other dolls, is one of their members.
Off the top of my head, I believe they were also mentioned to have been developing the 'Project: Society of Machines' when Anne landed on Arin (where Central is) during the war. My guess is that was the prototype to whatever the hell this 'Seed' is that Anne is about to deploy.
The PPP wasn't too relevant to this chapter, so I didn't include it. But they'll show up next chapter! (Which will be, uh, sometime …)
