Proof step 5 from proof valid-eraseqw-unmap (previous step)

wlar[n, wl-entry(m1, erasing)][n0] = wl-entry(m, stat0), wlar[n] = wl-entry(m0, stat), n < # wlar, ∀ n. n ∈ q ↔ n < # wlar ∧ wlar[n].status = erasing ⊦ n0 ∈ q + eq-entry(n, lref) ' ↔ n0 < # wlar ∧ stat0 = erasing, n0 = n, stat = erasing

And obtained the following new goals

Proof step 6:
wlar[n] = wl-entry(m0, stat), wlar[n0] = wl-entry(m, stat0), n < # wlar, ∀ n. n ∈ q ↔ n < # wlar ∧ wlar[n].status = erasing ⊦ n0 ∈ q ↔ n0 < # wlar ∧ stat0 = erasing, n0 = n, stat = erasing
