Proof step 27 from proof addarrays-initdone (previous step)

⊦ ¬ initerror(class, addarrays(refs, ty, ints, i, st)) ∧ ¬ initundone(class, addarrays(refs, ty, ints, i, st)) ↔ initdone(class, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ initerror(class1, st) ↔ (jvmref -- mkfs(class1, void_type, `initstate' .field) ') × initval(error) ∈ st
Proof step 26:
⊦ ¬ (jvmref -- mkfs(class, void_type, `initstate' .field) ') × initval(error) ∈ addarrays(refs, ty, ints, i, st) ∧ ¬ initundone(class, addarrays(refs, ty, ints, i, st)) ↔ initdone(class, st)

Rule argument
