The common cause is their entanglement, which happens at their manufacture.

Or can you find me anything that directly counters this explanation?

I think you mean that you know there is statistical but you're wondering
about temporal.

I'm saying, the entanglement causes the statistical, and happens ahead of
time for both photons so there's your temporal.

Their common cause is their entanglement.  If you know they are entangled,
they you know there was an entanglement.  It couldn't be much simpler to
