Proof step 5 from proof init-out-01 (previous step)

⊦ _uninit ∈ st[_out, val] ∧ ¬ jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∨ jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st[_out, val] ∧ st[jvmref -- mkfs(class1, void_type, `initstate' .field) '] = initval(undone) ↔ jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∧ st[jvmref -- mkfs(class1, void_type, `initstate' .field) '] = initval(undone) ∨ ¬ jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∧ _uninit ∈ st

Heuristic pl case distinction applied rule case distinction

And obtained the following new goals

Proof step 4:
