Proof step 1 from proof lpt-free-unref-remove-wbufs (conclusion)

⊦ lpt-free-unref(remove-wbufs(ns, lpt)) ↔ lpt-free-unref(lpt)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ (∀ n. n < # lpt ∧ lpt.mapIndices(ns, λ lp. lp.size:= LEB_SIZE)[n].flags = LP_FREE → lpt.mapIndices(ns, λ lp. lp.size:= LEB_SIZE)[n].ref-size = 0) ↔ (∀ n. n < # lpt ∧ lpt[n].flags = LP_FREE → lpt[n].ref-size = 0)

Rule argument
