Proof step 9 from proof okarray-put-nopath-01 (previous step)

okarray(val, byte_type, i, st), is_valid_ref(str, r0, st) ⊦ path∃(str, val .refval, r0, st), okarray(val .refval, byte_type, st[r0 -- sk, val1]) ∧ (st[r0 -- sk, val1][val .refval -- _length]) .intval = i

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 8:
val = refval(r) ∧ is_referencevalue(val), okarray(val, byte_type, i, st), is_valid_ref(str, r0, st) ⊦ path∃(str, r, r0, st), okarray(r, byte_type, st[r0 -- sk, val1]) ∧ (st[r0 -- sk, val1][r -- _length]) .intval = i
