Proof step 26 from proof junkrefs-levelsubset (previous step)

st[r -- i '] = refval(r0), level⊆(str, str0), st[r -- _type] .type ≤ ty, 0 ≤ i, 0 < st[r -- _length] .intval, is_array(str0, r, st), is_array(str, r, st), i < st[r -- _length] .intval, junkrefs(str0, r0 ' + refs, st[r -- _type] .type .type, st), ∀ str1, str2, ty0, st0. level⊆(str1, str2) ∧ junkrefs(str2, r0 ' + refs, ty0, st0) → junkrefs(str1, r0 ' + refs, ty0, st0) ⊦ r = jvmref, junkrefs(str, r0 ' + refs, st[r -- _type] .type .type, st)

And closed the goal!
