Opinions on framing design

Simply call for a SE and be done with it otherwise your getting / giving useless opinions.

minimum bearing for a conventional rafter is 1-1/2" on a wood framed bearing wall and 3" on masonry or concrete. So the 2" is fine.
Minimum nailing to the top plate is (2) 16d common nails so the 8d are suspect.
Can not tell from the picture which way the ceiling joists are running I'm assuming they are not running parallel judging by the seat cut on the rafters on the bearing wall. If that is the case the rafters would be required too have 2"x4" rafter ties or a wall or girder at the ridge.
In both cases the rafters are required too have collar ties or ridge straps.

I was recently told by an engineer that if you use four spikes into a 2x4, you do not need ties. Cutting a birds mouth like Kent suggests and diving the nail four spike at the birds mouth, might be a better way. The reality is; is the contractor going to take the time to cut the birds mouth? I have never see any expect on exterior walls and those on very few homes. Now if you live in areas of huricanes then I would image huricane ties are needed.

That way you resist lateral loads and have full bearing on the 2x4 and you have enough room at the bottom (level) cut of the rafter to get 2- 16d toenails in one side and one in the other. Poor quality framing. 8d nails are a defective installation in this situation. I'd call for correction by a qualified contractor for the fasteners at least.

Bingo... seat cut and blocking. We do that where stringers drop on concrete, cut a profile of 2x4/6 out of the base of stringers and a PT plate has been applied/tapcon'd/ bolted to concrete/foundation depending on setup. Similar application, just on top of gar wall.
