Proof step 2 from proof delta-erase-worker-helper (previous step)

wlar0 = wlar, wlar[n].ec + UBI_ERASE_RETRIES < ecs(wlar).max, n < # wlar ⊦ [ubi_erase_worker_helper#(n; wlar, apebs; err)] ∃ m, stat. m ≠ 0 ∧ m ≤ UBI_ERASE_RETRIES + 1 ∧ Δ wlar + m = Δ wlar0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
wlar0 = wlar, wlar[n].ec + UBI_ERASE_RETRIES < ecs(wlar).max, n < # wlar ⊦ [ubi_erase_worker_helper#(n; wlar, apebs; err)] ∃ m. m ≠ 0 ∧ m ≤ UBI_ERASE_RETRIES + 1 ∧ Δ wlar + m = Δ wlar0
