after my wheel has been trued, one of the spokes in the area of the wobble has gone almost back to
steel colour (they should be black!) over a good 80-100mm length. if you look closely there are actual spiral twists around it. now, i think this spoke has been twisted and consequently passed its elastic limit (the wobble cannot be trued out) if you run a finger along it, the spoke gets thinner where the discolouration has occurred, just like butting (but not at the correct place!)
a lot of words, but does this sound logical to you lot? have you seen it before?
