Proof step 9 from proof bflipset-subarray-erase-old-add (previous step)

wlar[n1] = wl-entry(m, stat), 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, stat = used

Heuristic quantifier applied rule all left

And closed the goal!
