Proof step 4 from proof okfieldinits-abstract (previous step)

fs = mkfs(class, ty, fieldvar1), okfieldinits(class, fis0), mkfs(class, abstract_type, fieldvar) ' ∈ (fs ' × initial_value(ty)) ' + fis0, ∀ class0, fieldvar0. ¬ okfieldinits(class0, fis0) ∨ ¬ mkfs(class0, abstract_type, fieldvar0) ' ∈ fis0 ⊦ ty = abstract_type

And obtained the following new goals

Proof step 3:
okfieldinits(class, fis0), mkfs(class, abstract_type, fieldvar) ' ∈ fis0, ∀ class0, fieldvar0. ¬ okfieldinits(class0, fis0) ∨ ¬ mkfs(class0, abstract_type, fieldvar0) ' ∈ fis0 ⊦ ty = abstract_type
