"Track minimum radius could be dictated by a multi axle, four or more wheeled vehicle on a rigid chassis/wheelbase.
It's why they have swivelling bogeys on railway wagons.
A long rigid chassis can't negotiate tight curves."

I noticed your proposition of railway-like swivelling bogies, the only solution to accomodate long chassis in deep curved ruts.
Indeed, it is hard to imagine a classical four-wheeled oxcart with only front-axle swivelling system turning in some cart ruts places.

But in my view, if wheeled cart remains the solution (ok, only for some dummy persons like me), it must have been limited to single rigid axle, e.g. two-wheeled, to negociate even the tight curves sometimes met along the path. And sleds, although a better system for very heavy stones may have had difficulties in such curves.

Reconcile complementary logical solutions is not that easy.....

A twin bogies cart does not seem to have been devised during ancient remote times, it indeed looks like a very sophisticated device for those remote times and hard to build only of wood, whereas a single bogie cart seems unnecessary, unless you need to rotate the supporting plate regarding axle direction, maybe. But strong rotation control system is required, then.
I could not find exactly when the bogie was first introduced in transportation systems.
