Proof step 2 from proof delta-wear-leveling (previous step)

bflipset = ∅, wlar0 = wlar, ubi-cons(apebs, vols, wlar, q, bflipset, n0, n1), ubi-io-inv(apebs) ⊦ ⟪ubi_wear_leveling_worker#(LEB_SIZE, EB_PAGE_SIZE; vols, wlar, q, bflipset, n0, n1, apebs; err)⟫ (err = ESUCCESS → Δ wlar < Δ wlar0)

And obtained the following new goals

Proof step 3:
# apebs = # wlar, bflipset = ∅, wlar0 = wlar, ubi-io-inv(apebs), unique-sqns(apebs), valid-ebatbl(apebs, wlar, vols, n0), valid-eraseq(q), valid-eraseq(wlar, q), valid-eraseq(apebs, q), valid-global-sqn(apebs, n1), valid-vtbl(apebs, vols, wlar, n0), valid-wl(apebs, wlar), ¬ VTBL_VOLID ∈ vols ⊦ ⟪ubi_wear_leveling_worker#(LEB_SIZE, EB_PAGE_SIZE; vols, wlar, q, bflipset, n0, n1, apebs; err)⟫ (err = ESUCCESS → Δ wlar < Δ wlar0)
