Research Wiki is the proposed name for the intermediate page wiki. This used to be called Opinion Wiki. Here edits, votes and bets are resolved and maybe disputed by formal factions, by dissensus, or whatever other unwise means may be defaulted to. In other words, it's where what is true enough to publish is decided. See Talk:Development_Wiki for debate on the naming scheme.
The Signal Wiki (formerly Content Wiki) is where the actual Consumerium buying signal is edited for various media or legal reasons, before it reaches the various worn device, retail shelf, checkout counter, and web interfaces where Consumerium Service access happens. The Development Wiki is the one you're looking at right now, and it temporarily also serves some Reserach Wiki functions for the moment.
