If this is what you can see, think about what they'll be hiding.
This shows beyond doubt they can't even spell craftsmen and will throw up anything IF they think they can get by with it.
You need to double check each & every single thing they do .
That crap needs to come down and I wouldn't settle for them toenailing the replacements in.
They screwed it up, make them fix it right or you can call your city or county building inspector, then they'll be fixing everybody's house.
These kind of yahoos will likely put 1 or 2 nails when common sense or code calls for 3 or 4
I'd also carry a 3 ft level and check each & every wall for plumb ,
use a measuring tape and check for square [measured diagonally both measurements should be the same or very close]
This is the skeleton of your home if it's not right , nothing will be right.
You're paying for this and will be for many years, If you accept crap work believe me you'll get it in spades.
Oh and BTW what is the primary language spoken by your so called "framers".?
