It’s the tensioner for a Pinion gearbox. Unfortunately they don’t use ISCG so it’s bolted to the Blackspire bash taco (holes drilled to accommodate), which is then mounted to the ISCG.
What’s cool about it rather than a derailleur hanger mounted tensioner is that it moves up and out of harms way when you smoke it on something.
It doesn’t have a clutch, but the spring tension and path of travel make it really quiet too.
The Pinion distributor in the states stocks all kinds of small parts and they seem very friendly and knowledgeable- though I’ve had limited dealings.

I’ll note as well it’s much better adjusted in photo two.
