Proof step 6 from proof okarrays-one-01 (previous step)

sk .fs = mkfs(class, ty, fieldvar) ⊦ okarrays(r, (sk × val) ', st) ↔ is_integervalue(val) ∧ ¬ is_indexkey(sk) ∧ is_arraytype(ty) ∧ okarray(st[r -- sk], ty .type, val .intval, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
sk .fs = mkfs(class, ty, fieldvar) ⊦ okarrays(r, (sk × val) ', st) ↔ is_integervalue(val) ∧ ¬ is_indexkey(sk) ∧ is_arraytype(ty) ∧ okarray(st[r -- sk], ty .type, val .intval, st)
