Sadly I never thought to trying to publish a white paper with my co workers while I was working on this. I'd love the chance to do so. We did do many internal company presentations on the matter however.
That being said as far as I know there isn't any published works on a "Reverse Query Engine" or RQM for short which is the name we settled on internally for this subsystem within Firestore.
