Proof step 25 from proof decode-contract (previous step)

n < ENCODED_ELEM_SIZE, n < # buf, n < EB_PAGE_SIZE, is-encoded(a, subarray(buf, 0, ENCODED_ELEM_SIZE)), ENCODED_ELEM_SIZE ≤ # buf, ENCODED_ELEM_SIZE ≤ EB_PAGE_SIZE, EB_PAGE_SIZE ≤ # buf, ∀ n0. n0 < EB_PAGE_SIZE → buf[n0] = empty ⊦ buf[n] = empty
