Proof step 8 from proof valid-eraseqw-subarray-shift (previous step)

wlar[n0] = wl-entry(m0, stat0), n < # wlar, ∀ n0. n0 ∈ q ↔ n0 < n ∧ wlar[n0].status = erasing ⊦ n0 ∈ q ↔ ¬ n < n0 ∧ stat0 = erasing, n0 = n, stat = erasing

Heuristic cut applied rule cut formula

And obtained the following new goals

Proof step 9:
wlar[n0] = wl-entry(m0, stat0), n < # wlar, n0 ∈ q, ∀ n0. n0 ∈ q ↔ n0 < n ∧ wlar[n0].status = erasing ⊦ n0 ∈ q ↔ ¬ n < n0 ∧ stat0 = erasing, n0 = n, stat = erasing
Proof step 15:
wlar[n0] = wl-entry(m0, stat0), n < # wlar, ∀ n0. n0 ∈ q ↔ n0 < n ∧ wlar[n0].status = erasing ⊦ n0 ∈ q ↔ ¬ n < n0 ∧ stat0 = erasing, n0 = n, stat = erasing, n0 ∈ q

Rule argument

fma: n0 ∈ q
