OB,
I don't dismiss that the swinger closes the face by simply holding on to the club, but the force that creates the turn & roll is still delivered by the golfer's hands.

Wrong. it is cf acting on the clubface because cf pulls objects in line and on plane with their cog this what the club is doing seeking it's cog and in so doing it closes as it seeks it

The nature of a sequenced release as dictated by cf longitudinal acceleration the club passively switches ends rotates over
