Proof step 31 from proof inv-write (previous step)

PEB_SIZE = n1 + m2 + n, PEB_SIZE = n0 + m1, pebs[m3] = mkpeb(buf0, m1, false), m3 < # pebs, n3 < n1, is-aligned(m2, EB_PAGE_SIZE), is-aligned(n, EB_PAGE_SIZE), is-aligned(m1, EB_PAGE_SIZE), mtd-cons(pebs), m1 ≤ m2, n2 + n ≤ # buf, m2 + n ≤ PEB_SIZE, m1 ≤ PEB_SIZE, ∀ n4. n4 < n0 → buf0[m1 + n4] = empty ⊦ buf0[(m2 + n) + n3] = empty

Proof step 32:
PEB_SIZE = n0 + m1, PEB_SIZE = n1 + m2 + n, pebs[m3] = mkpeb(buf0, m1, false), n3 < n1, m3 < # pebs, is-aligned(m1, EB_PAGE_SIZE), is-aligned(n, EB_PAGE_SIZE), is-aligned(m2, EB_PAGE_SIZE), mtd-cons(pebs), m1 ≤ PEB_SIZE, m2 + n ≤ PEB_SIZE, n2 + n ≤ # buf, m1 ≤ m2, (m2 + n) + n3 - m1 < n0 → buf0[m1 + ((m2 + n) + n3 - m1)] = empty ⊦ buf0[(m2 + n) + n3] = empty
