That does not restrict what a problem statement can specify.
If the computed mapping differs from the specified one the decider does
not solve the problem.
 

int sum(int x, int y) { return x + y; } sum(2,3) cannot return the sum
of 5 + 6.
 
DD correctly simulated by HH does have provably different behavior than
DD(DD) so HH is is not allowed to report on the behavior of DD(DD).

Huh? Then HH is not a correct simulator if it produces different
behaviour. Why is it not allowed?
