It would show on the edges too (and on Keycode)

I don't know how, but probably here (if (3) is not the answer).

As ((the density change is also across the unexposed frame line)) and you
are not seeing stripes, it's not a camera speed variation nor a loose
It could be some sort of in-camera bloop white light flashing during
pulldown; worth checking.
> 4 Pre-exposure from the bag?
It would show on the edges, and the half sec period will not be that
Now two questions:
16 or 35 mm stock?
Is the Keycode density totally unaffected ?
