just noticed the rear wheel on my hemlock is not central, is set to one side by a few mm. wheel runs true has even spoke tension. its not caused any issues, only noticed it today when cleaning. complete rear end is new so im sure nothings bent.
any one come across this before? should i be worried about it?

Dish? Pop wheel in wrong way round, is it still offset? which way?

Or spacers put in on the wrong side during a hub rebuild ?
