Proof step 1 from proof valid-wl-erasing-invalidate (conclusion)

m < # apebs ⊦ # apebs = # wlar ∧ ¬ valid-peb(apeb) ∧ valid-wl(apebs, wlar) ∧ wlar[m] = wl-entry(m0, erasing) ∧ ¬ apeb.bad → valid-wl(apebs[m, apeb], wlar)

System applied rule normalize

And obtained the following new goals

Proof step 2:
# apebs = # wlar, wlar[m] = wl-entry(m0, erasing), m < # apebs, valid-wl(apebs, wlar) ⊦ apeb.bad, valid-peb(apeb), valid-wl(apebs[m, apeb], wlar)
