Cognitive Code complexity

You can find all about it here:

I was looking at the cognitive code complexity of the anytype-heart (which is written in my favourite language), but there are some complex parts in there. (I use a max complexity of 11 in my own projects, but I've used 50 here)

Here's the result:
