Proof step 12 from proof is_array-byte-noref (previous step)

st[r -- _type] .type = mkarraytype(byte_type), st[r -- i '] = refval(r1), is_typevalue(st[r -- _type]), r -- _type ∈ st, 0 < st[r -- _length] .intval, 0 ≤ i, r ∈ st, i < st[r -- _length] .intval, okarray(r, byte_type, st) ⊦ r = jvmref

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 11:
st[r -- _type] = typeval(ty), ty = mkarraytype(byte_type), st[r -- i '] = refval(r1), is_typevalue(st[r -- _type]), r -- _type ∈ st, 0 < st[r -- _length] .intval, 0 ≤ i, r ∈ st, i < st[r -- _length] .intval, okarray(r, byte_type, st) ⊦ r = jvmref
