Proof step 2 from proof mapped-pebs-unused (previous step)

wlar[n] = wl-entry(m, stat), n < # wlar, valid-ebatbl(apebs, wlar, vols, n0), n ∈ mapped-pebs(vols) ⊦ stat = used

And obtained the following new goals

Proof step 3:
vols[v][m0] = ⌜n⌝ , wlar[n] = wl-entry(m, stat), m0 < # vols[v], n < # wlar, v ∈ vols, ∀ v, m, n1. vols[v][m] = ⌜n1⌝ ∧ v ∈ vols ∧ m < # vols[v] ↔ wlar[n1].status = used ∧ n1 < # apebs ∧ n1 < # wlar ∧ apebs[n1].vidhdr.valid? ∧ apebs[n1].vidhdr.vol = v ∧ apebs[n1].vidhdr.leb = m ∧ n1 ≠ n0 ⊦ stat = used
