Proof step 11 from proof okarray-1dim-03 (previous step)

⊦ r = r0, okarray(refval(r), boolean_type, i, addarray(r0, ty0, i0, st)) ↔ okarray(refval(r), boolean_type, i, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ okarray(val, ty, i, st) ↔ okreftype(val, mkarraytype(ty), st) ∧ val .refval ≠ jvmref ∧ (val .refval -- _length) × intval(i) ∈ st ∧ 0 ≤ i ∧ is_arrayref(val .refval, i, st) ∧ (∀ j. 0 ≤ j ∧ j < i → oktype(st[val .refval -- j '], ty, st))
Proof step 10:
⊦ r = r0, okreftype(refval(r), mkarraytype(boolean_type), addarray(r0, ty0, i0, st)) ∧ refval(r) .refval ≠ jvmref ∧ (refval(r) .refval -- _length) × intval(i) ∈ addarray(r0, ty0, i0, st) ∧ 0 ≤ i ∧ is_arrayref(refval(r) .refval, i, addarray(r0, ty0, i0, st)) ∧ (∀ j. 0 ≤ j ∧ j < i → oktype(addarray(r0, ty0, i0, st)[refval(r) .refval -- j '], boolean_type, addarray(r0, ty0, i0, st))) ↔ okarray(refval(r), boolean_type, i, st)
