I cannot find a relay for the low beam bulbs at all. I just made a new
discovery though: the positive side of the low-beam fuse sockets are live,
even when the lights are switched off.

How does this reconcile with "What I have now discovered is that there
is no voltage
between one side of the fuse socket and the other"?
