We are talking about undetectable reality. Obviously ALL math is
undetectable. Indetectable certainly does mean no observable
consequences. Words actually mean things. If there are some sort of
secondary consequences then obviously that is detectability.

But it is interesting to draw the line between indetectable reality, and
unreal fantasy (mathematics). Nobody can detect the square root of minus
one or even "2" for that matter, yet as an analogy to reality that sort
of thing has proven more fruitful than one might expect for fantasy.
