Proof step 7 from proof okfieldinits-one (conclusion)

⊦ okfieldinits(class, (sk × val) ') ↔ is_fskey(sk) ∧ val = initial_value(sk .fs .type) ∧ sk .fs .class = class ∧ sk .fs .type ≠ abstract_type

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
⊦ okfieldinits(class, (sk × val) ') ↔ ¬ is_indexkey(sk) ∧ val = initial_value(sk .fs .type) ∧ sk .fs .class = class ∧ sk .fs .type ≠ abstract_type

Rule argument
