YES
Did not drop rules.
Inlined conditions for 0 rules.
Left-inlined conditions for 0 rules.
Due to Ifrit-method removed 0 infeasible rules.
Did not use redundant rules method.
INFEASIBLE because

problem pos(0()) ->* true()
obtained from
root-nonreachability
requires
  [problem obtained from
  narrowing is proven infeasible
  using the symbol transition graph on
  false() ->* true()
  ,problem obtained from narrowing
  is proven infeasible
  since unification failed for
  pos(0()) ~ true()]

where | is used as a fresh function symbol, since it is illegal in the input format.
