Proof step 2 from proof lf-valid-vtbl-neq-erasing (previous step)

wlar[m] = wl-entry(m0, erasing), n = m, valid-vtbl(apebs, vols, wlar, n) ⊦

Heuristic simplifier applied rule simplifier

And closed the goal!

Rule argument

Used simplifier rules: ⊦ used ≠ erasing; (s)%valid-vtbl-wlar-status: ⊦ wlar[n0] = wl-entry(m, stat) ∧ valid-vtbl(apebs, vols, wlar, n0) → stat = used; (forward) from specification ubi-base
