Proof step 7 from proof bflipset-subarray-erase-old-add (previous step)

wlar[n1] = wl-entry(m, stat), n < n1, n0 + 1 < # wlar, n < # wlar, n0 < n, n0 < # wlar, n1 ∈ bflipset, ∀ n1. n1 ∈ bflipset → n1 < n ∧ wlar[n1].status = used ⊦ # bflipset = 0, bflipset = ∅, n1 = n, n1 = n0

And obtained the following new goals

Proof step 8:
wlar[n1] = wl-entry(m, stat), n0 < n1, n < n1, n0 + 1 < # wlar, n < # wlar, n0 < n, n0 < # wlar, n0 + 1 < n1, n1 ∈ bflipset, ∀ n1. n1 ∈ bflipset → n1 < n ∧ wlar[n1].status = used ⊦ # bflipset = 0, bflipset = ∅, n1 = n, n1 = n0
