Proof step 8 from proof okfieldinits-class (previous step)

is_fskey(sk) ∧ val = initial_value(sk .fs .type) ∧ sk .fs .class = class0 ∧ sk .fs .type ≠ abstract_type ∧ okfieldinits(class0, fis0), ∀ class0, class, ty, fieldvar. okfieldinits(class0, fis0) ∧ mkfs(class, ty, fieldvar) ' ∈ fis0 .keys → class = class0 ⊦ class = class0, mkfs(class, ty, fieldvar) ' ≠ sk ∧ ¬ mkfs(class, ty, fieldvar) ' ∈ fis0 .keys
