Heuristic quantifier closing applied rule exists right

And closed the goal!

pos: right 3 terms: buf, buf1

Additional information

Used simplifier rules: ⊦ is-encoded(nx0, buf) → (is-encoded(nx1, buf) ↔ nx0 = nx1); (s)% ⊦ is-encoded(rnd, buf) → (is-encoded(rnd0, buf) ↔ rnd = rnd0); (s) Used terms: buf, buf1
