YES
Did not drop rules.
Inlined conditions for 1 rules:
  tc(x) -> tc(z()) 
   | pin(x) ->* pout(z())
Left-inlined conditions for 0 rules.
Due to Ifrit-method removed 0 infeasible rules.
Did not use redundant rules method.
INFEASIBLE because

problem |(pin(x1)
         ,tc(z())) ->* |(pout(z()),x2)
obtained from input
requires
  [problem pin(x1) ->* pout(z())
  obtained from
  root-nonreachability
  requires
    [problem obtained from
    narrowing is proven infeasible
    using TCAP on
    pout(c()) ->* pout(z())
    ,problem obtained from narrowing
    is proven infeasible
    using TCAP on
    pout(b()) ->* pout(z())
    ,problem obtained from narrowing
    is proven infeasible
    since unification failed for
    pin(x1) ~ pout(z())]]

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