Proof step 1 from proof lf-valid-wl-free-emptyvidhdr (conclusion)

n < # wlar, n < # apebs ⊦ wlar[n] = wl-entry(m, free) ∧ valid-wl(apebs, wlar) ∧ ubi-io-inv(apebs) → apebs[n].vidhdr = empty ∧ apebs[n].echdr.valid? ∧ apebs[n].fill = 0

System applied rule normalize

And obtained the following new goals

Proof step 2:
wlar[n] = wl-entry(m, free), n < # apebs, n < # wlar, ubi-io-inv(apebs), valid-wl(apebs, wlar) ⊦ apebs[n].vidhdr = empty ∧ apebs[n].echdr.valid? ∧ apebs[n].fill = 0
