Proof step 8 from proof validsubset-okbytearray (previous step)

(∀ r, ty. validref(str, r, ty, st) → validref(str, r, ty, st0)) ∧ (∀ r. ¬ r ∈ st ∧ r ∈ st0 → ¬ junkref(str, r, st0)), okbytearray(r, st) ⊦ okbytearray(r, st0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
okbytearray(r, st), ∀ r. ¬ r ∈ st ∧ r ∈ st0 → ¬ junkref(str, r, st0), ∀ r, ty. validref(str, r, ty, st) → validref(str, r, ty, st0) ⊦ okbytearray(r, st0)
