Proof step 2 from proof crash-neutral-read-data (previous step)

apebs0 = apebs, ubi-io-inv(apebs), ubi-io-read-data-pre(n, n0, n1, n2, buf, apebs) ⊦ ⟨aubi_io_read_data#(n, n0, n1, n2, apebs; buf; bitflips, err)⟩ (apebs0 = apebs)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
n < # apebs, ubi-io-inv(apebs), n1 + n2 ≤ # buf, n0 + n2 ≤ LEB_SIZE, ¬ apebs[n].bad ⊦ ⟨aubi_io_read_data#(n, n0, n1, n2, apebs; buf; bitflips, err)⟩ true

Rule argument
