Following up to Tim Downie

The live & neutral look to be tinned with solder which I
thought was a no-no.

is that right? I didnt know.

Dunno for sure (I sure someone will come along who does) but I seem to
recall it causes the wires to come loose as the solder undergoes plastic
deformation with heating & cooling cycles.

It's more that the solder deforms as the screw is tightened but has zero
springback as the screw changes slightly with temperature, leading to it
working loose. The copper on its own has a little elasticity.
