- If you don't mind, can we look at this again? I found several discussions, but they are old and don't convince me.

Here is a screenshot from Einstein's 1905 ELECTRODYNAMICS OF MOVING BODIES:
My understanding is that here Einstein says that the rod, the 2 observers and the 2 clocks are in the moving system, one observer & clock at each end of the rod. From their point of view they are not moving. They can very well be enclosed in an opaque box, no windows, the motion is uniform, so they can't tell if they move or not (relative to any other system). So they can apply the criterion of synchronism that was described in §1 for synchronization of not moving clocks. Does Einstein here say (so it seems to me) that these 2 observers see the ray of light moving with the speed V-v from A to B and with speed V+v from B to A?
