Proof step 37 from proof inv-write-data-wl (previous step)

apebs[n2] = mkpeb(aehdr, avhdr, buf1, 0, false), n1 = align↑(datasize(buf, n1), EB_PAGE_SIZE), aehdr.valid?, avhdr.valid?, n2 < # apebs, ubi-io-inv(apebs), n1 ≤ LEB_SIZE, n1 ≤ # buf ⊦ datasize(buf, n1) = 0, ∃ err0. ⌊err0⌋ ∨ err0 = ESUCCESS
