Proof step 2 from proof inv-write-vidhdr (previous step)

pebs[m0].fill = EB_PAGE_SIZE, m = EB_PAGE_SIZE, avhdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ ⟪ubi_io_write_vidhdr#(m0, avhdr, m; pebs; err)⟫ mtd-cons(pebs), pebs[m0].bad

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
pebs[m0].fill = EB_PAGE_SIZE, avhdr.valid?, m0 < # pebs, mtd-cons(pebs), ¬ pebs[m0].bad ⊦ ⟪ubi_io_write_vidhdr#(m0, avhdr, EB_PAGE_SIZE; pebs; err)⟫ mtd-cons(pebs)
