Proof step 5 from proof valid-vtbl-update-vols (previous step)

avhdr.leb = VTBL_LNUM, avhdr.vol = VTBL_VOLID, apebs[n0] = mkpeb(aehdr, avhdr, buf, m, boolvar), wlar[n0] = wl-entry(m0, stat), stat = used, n0 < # wlar, n0 < # apebs, v ∈ vols ⊦ is-encoded(to-vtbl(vols)[v, # vols[v]], buf) ↔ is-encoded(to-vtbl(vols), buf)
