Just checked. And from the NEC, appears to me that if the attic has
stairs, then the cable needs to be protected by guard strips if it's
run across rafters and within 7 ft of the attic floor. If it's only
accessible by scuttle hole, then said protection only applies within
6 ft of the scuttle hole. 320.23 is what applies. That section is
for type AC cable, but in the NM section it says that section also
applies to NM.
Perhaps you are not picturing what I have correctly.
The Romex is stapled to the ridge board. It doesn't run across the rafters.
The rafters are a good inch above the Romex. In other words, it closely
follows a running board - the ridge board - as required/allowed by 320.15.

320.15 doesn't specifically address attics. 320.23 does and it says that
any cable run across the face of joists, rafter or studs in an attic
has to be "protected by a guard strip" at least as high as the cable, unless
it's over 7 ft above the floor of the attic. It doesn't draw a distinction
between parallel or perpendicular. If I understand it correctly,
you have it stapled to the bottom of the ridgeboard. While the code
doesn't specifically say ridge board, it sounds like it would fall into
the same category. They want the cable either on the side of the joist, stud,
rafter, or if it's on the face, then protected by something at least as high as it is. At least that is my understanding.
Again, I don't see anything wrong with what you did from a safety
standpoint. I'm just citing what the code says. If they say you can't
run a romex up the bottom of a rafter without a guard strip,
unless it's 7 ft above the floor, then I would think the same applies to your ridgeboard location.
Allow me to try and clear this up.
Assume the white line in the photo below is the Romex. It comes up into the
attic, runs along the rafter and then runs along what I call the "face" of
the ridge board (the "8" in a 1x8).
Thanks...I figured I was OK.
The only thing I didn't mention was that I ran out of Romex so the wiring
is a mixture of Romex, BX cable, K&T and some bell wire. The bell wire is
only used for the Danish 107-2-DI receptacle that I had lying around. If
you trim and bend the prongs of a standard US plug you can get it into
those Danish receptacles...sort of.
I don't think it's anything an inspector would have an issue with. ;-)
