Lap siding and rain screen on gable ends with no external sheathing
This question may sound silly to anyone who has actually put siding on a building but I’m having a hard time picturing it. For my energy efficient shed, I was going to skip external sheathing since I am putting plywood on all the interior walls and that will provide the structural rigidity I need.
My wall assembly was going to be:
From inside to outside:
5/8 plywood
Vapor barrier
2*6 frame with batt insulation
Tyvek WRB
Furring strips attached to studs
HardiePlank Lap siding
I have figured out how that will work in most locations but as I think about details at corners, around doors and windows, and at the top edges of the gables, I am realizing that I may occasionally need to put in a nail through the siding where I don’t have a stud. In those locations, I assume I could normally put a small piece of furring strip screwed to sheathing as shown in this image from Fine Homebuilding.
Am I going to create a major headache for myself by skipping the external sheathing?

Canada_Deck,
Run an angled furring strip, or wider piece of plywood of the same thickness, on the top plates of the gable wall. It will catch the ends of the cladding.
