I'm going with bacteria but for lols I tell you what might have happened at the end of the turn.
Above Vulcano's Forge constructors begin construction of a massive reflective surface. 74/100 construction goes smoothly
The newly named forge increases industry. 55/100 construction could go better two miners had kinks in their plates and will need to be repaired.
88/100 In the asteroid belt nearest massive chunks of ice, carbon, and nitrogen are located and quickly and efficiently moved into orbit ready to be dropped when the terraformer main AI (you) deams nessecary. More can be found and moved.
On New Terra the new solar array is aimed and 78/100 fired at the planet warming it up, about 5 ocean however it lacks greenhouse gasses so the array will need to be constantly on it.
Atmosheric density: If your in 300 foot deep canyon its a quarter of being on top of Everest.
Composition: Low methane though plenty of carbon and even some traces of oxygen. No real poisons that can't be easily dealt with.
The Bacteria are created: 77/100 (you guys have pretty nice luck) The bacteria are obligate anaerobe so that will solve some problems of disposal, moreover the soil turns out to be modestly nitrogen rich so I took the liberty of creating fixers.
Temprature usually is freezing 32 F or for you Metric users 0C
Low plate movemont shouldn't be a problem.
crust thickness 20 miles
soil isn't to badly packed.
magnetic field is strong enough for the task at hand.
Relay stations: 49/100 1 constructor is destroyed and three more are damage by accidently crossing the main beam.
You manage to make 2,000,000 worth of humans in comfortable positions though more if not, however atmosphere is not their yet.
Assets in a minute: 5 synthesizers to make life.
