Proof step 9 from proof bflipset-subarray-next (previous step)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 10:
wlar[n0] = wl-entry(m, stat), n < # wlar, n < n0, n0 ∈ bflipset, ∀ n0. n0 ∈ bflipset → n0 < n ∧ wlar[n0].status = used ⊦ # bflipset = 0, bflipset = ∅, n0 = n

Rule argument
