Proof step 12 from proof ac-in-03 (previous step)

sk .fs = mkfs(class0, ty, fieldvar), jvmref -- _type ∈ addclass(class1, (sk × val) ' + fis0, st), jvmref ∈ addclass(class1, (sk × val) ' + fis0, st), ∀ class, st0. jvmref -- _type ∈ addclass(class, fis0, st0) ∧ jvmref ∈ addclass(class, fis0, st0) → jvmref -- _type ∈ st0 ⊦ _type = sk, _type ∈ fis0, jvmref -- _type ∈ st, ¬ is_indexkey(sk) ∧ class0 ≠ class1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ is_indexkey(fv .1) → addclass(class, fv ' + fis, st) = addclass(class, fis, st)
Proof step 9:
¬ is_indexkey((sk × val) .1), sk .fs = mkfs(class0, ty, fieldvar), jvmref -- _type ∈ addclass(class1, (sk × val) ' + fis0, st), jvmref ∈ addclass(class1, (sk × val) ' + fis0, st), ∀ class, st0. jvmref -- _type ∈ addclass(class, fis0, st0) ∧ jvmref ∈ addclass(class, fis0, st0) → jvmref -- _type ∈ st0 ⊦ _type = sk, _type ∈ fis0, jvmref -- _type ∈ st, ¬ is_indexkey(sk) ∧ class0 ≠ class1
Proof step 11:
is_indexkey((sk × val) .1), sk .fs = mkfs(class0, ty, fieldvar), jvmref -- _type ∈ addclass(class1, fis0, st), jvmref ∈ addclass(class1, fis0, st), ∀ class, st0. jvmref -- _type ∈ addclass(class, fis0, st0) ∧ jvmref ∈ addclass(class, fis0, st0) → jvmref -- _type ∈ st0 ⊦ _type = sk, _type ∈ fis0, jvmref -- _type ∈ st, ¬ is_indexkey(sk) ∧ class0 ≠ class1
