Proof step 80 from proof inv-write (previous step)

n = 0, m2 < # avols[v], ebm-cons(avols), is-aligned(m1, EB_PAGE_SIZE), is-aligned(n, EB_PAGE_SIZE), v ∈ avols, m1 + n ≤ LEB_SIZE, n + n2 ≤ # buf, avols[v][m2].mapped? → avols[v][m2].fill ≤ m1, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪skip⟫ ebm-cons(avols), err0 = ESUCCESS, avols[v][m2].mapped?
