Didn't see this elsewhere in a search... saw that in 1.92 these might have been added as new.
The problem is that after researching Collective Manufacturing I, II, or even III, the Yor cannot build the indicated starbase module: Collective Mining I, II, III. They can build Mining Barracks and Battlestations, but even with both of those, no Collective Mining available.
I think I tracked down the problem: in StarbaseModules.xml, MiningCenter is listed as a pre-requisite for Collective Mining I, II, and III. But of course MiningCenter requires the tech Xeno Engineering which the Yor cannot research themselves. Trading for this tech and building a Mining Center does make Collective Mining available.
Was this intentional? Or should the pre-req for Collective Mining be switched to MiningBarracks instead of MiningCenter?
PS - if you edit the xml file manually (which I did), the change does not occur in the game you're playing - does it work only if you start a new game?
