Staples vs nails
(OP)
The inspector discovered that staples (1-3/4" x 16 ga.) were being used instead of 8d nails on residential roof sheathing. They are at same spacing specified for the nails i.e. 6:12" o.c.
Trusses are spaced at 24".
I can't anywhere in IRC Code that recommends nominal spacing for staples. The roof diaphragm is typically not designed for diaphragm shear due to wind forces.

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

Wood framing is redundant as designed, not so much as built.
You specify five nails, a contractor will use three. ... and people who don't know any better will use twelve. ... Habitat homes didn't even lose a shingle in Andrew.

I've also found that guys with nail or staple guns, whether paid or volunteer, tend to have no trouble pulling the trigger as many or more times than specified; their trouble is in hitting some framing while doing it.
