Proof step 28 from proof crash-neutral-write-data-wl (previous step)

apebs[m] = mkpeb(aehdr, avhdr, buf0, 0, false), n1 = align↑(datasize(buf, n1), EB_PAGE_SIZE), avhdr.valid?, aehdr.valid?, m < # apebs, n1 ≤ # buf, n1 ≤ LEB_SIZE, ∀ n. n < # apebs → ubi-io-peb-inv(apebs[n]) ⊦ buf0 = mkempbuf(LEB_SIZE), datasize(buf, n1) = 0
