The rules behind terraforming are currently sufficiently opaque that I can't be sure whether or not Orbital Mirrors not unlocking any options in my empire is a bug or just a lack of planets that fit the conditions. The terraforming rules badly need better documentation so that players can make intelligent choices about terraforming.

The late game techs need rejiggering and polish, so better documentation will need to wait until it's in a more solid place.

Yes, they do. And as Arioch says, the mechanics will probably change before they're finalized, which is why we've put off building much documentation into the game.

That said, if you do want to learn more about the current mechanics, there's at least one thread in the forum archives that may prove illuminating:
