Proof step 9 from proof valid-eraseq-next-erasing (previous step)

wlar[n] = wl-entry(m1, stat), m < # wlar, m < n, n ∈ q, ∀ n. n ∈ q ↔ n < m ∧ wlar[n].status = erasing ⊦ n = m, ¬ m < n ∧ stat = erasing

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 10:
wlar[n] = wl-entry(m1, stat), m < # wlar, m < n, n ∈ q, ∀ n. n ∈ q ↔ n < m ∧ wlar[n].status = erasing ⊦ n = m

Rule argument

Additional information

Used simplifier rules: ⊦ m < n → n ≠ 0; (s)%f: ⊦ m < n → n ≠ 0; (forward) from specification nat-basic
