I wonder whether you would have got a different result if you had dug down
to the expanded metal mesh and tested that?

Knowing little about electrics I didn't want to say but I thought some
mention of the metal mesh would have been made before now?

If it ended up near or touching some old cabling/pipework etc. Then
when the wet plaster was applied over it and now it's dry? Or am I
still not understanding electrics... ;-)
