It is the Mermin device, exactly as described in the experiment. The only
thing I am supposing here is the process of how the knobs are chosen on the
Mermin device.
If there is access to free will/pure randomness, then I propose using that
free will/pure randomness to select which knob positions are set on each
(spatially separated) Mermin device.
If this is done, then the normal superdeterministic explanation for the
observed quantum statistics no longer works.

If you go back to my original e-mail on this, I explain that all you need
are two polarized light filters. The positions 1-2-3 merely correspond to
rotations of this filter at 0, 120, and 240 degrees. Now use a source of
entangled photons and send one each towards one of the polarizing filters.
If the photon transmits through the filter, the green light flashes, if it
is absorbed by the filter, the red light flashes. That is all you need for
a mermin device, a polarized light filter.

Quantum theory says the correlation between whether the photons absorb or
transmit, when the filters are offset by 120 degrees is 25%. Here is the
math: https://www.google.com/search?q=cos(120+degrees)%5E2

David Mermin assumes nothing beyond how we understand polarizing light
filters to work, as quantum theory predicts, and as experiments confirm.
Nothing is "pre-supposed."

I hope my above explanation of how to build a mermin device helps. All you
need are polarized light filters and a protractor.
