Proof step 2 from proof inv-write-data-wl (previous step)

pebs[m0].fill = 2 * EB_PAGE_SIZE, m = EB_PAGE_SIZE, m0 < # pebs, is-aligned(n, EB_PAGE_SIZE), mtd-cons(pebs), n ≤ # buf, n ≤ LEB_SIZE ⊦ ⟪ubi_io_write_data_wl#(m0, n, buf, m; pebs; err)⟫ mtd-cons(pebs), pebs[m0].bad

And obtained the following new goals

Proof step 3:
pebs[m0].fill = 2 * EB_PAGE_SIZE, m0 < # pebs, is-aligned(n, EB_PAGE_SIZE), mtd-cons(pebs), n ≤ # buf, n ≤ LEB_SIZE, ¬ pebs[m0].bad ⊦ ⟪ubi_io_write_data_wl#(m0, n, buf, EB_PAGE_SIZE; pebs; err)⟫ mtd-cons(pebs)
