It seems only necessary to assume that, whatever this
polarization might be, it's the same for both photons of
any given pair, and it's produced via emission.

This "sameness" of polarization of both photons of
a pair via emission process is the unvarying condition
that's required to produce predictable rates of
coincidental detection.

It's not a variable, and because it's requirement
can be deduced, it's not hidden either.

So far, we have a local picture with no hidden variables.

The rate of coincidental detection varies as some circular
function of the angular difference between the transmission
axes of the two separated polarizers.

We've included a variable (unhidden) in the predictive
formula, but it still looks like a local picture to me.

Comments?
