Proof step 10 from proof ac-out (previous step)

sk .fs = mkfs(class1, ty, fieldvar), is_fskey(sk), ∀ class1, st, val. class1 = `java.lang.Object' .class ∨ addclass(class1, fis0, st[_out, val]) = (addclass(class1, fis0, st)[_out, val]) ⊦ addclass(class1, (sk × val0) ' + fis0, st[_out, val]) = (addclass(class1, (sk × val0) ' + fis0, st)[_out, val]), class1 = `java.lang.Object' .class

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 9:
sk = fs ', fs = mkfs(class1, ty, fieldvar), is_fskey(sk), ∀ class1, st, val. class1 = `java.lang.Object' .class ∨ addclass(class1, fis0, st[_out, val]) = (addclass(class1, fis0, st)[_out, val]) ⊦ addclass(class1, (sk × val0) ' + fis0, st[_out, val]) = (addclass(class1, (sk × val0) ' + fis0, st)[_out, val]), class1 = `java.lang.Object' .class
