Proof step 9 from proof refine-markbad (previous step)

apebs[m] = mkpeb(aehdr, avhdr, buf, m0, false), pebs[m] = mkpeb(buf0, m1, boolvar), ¬ boolvar, m < # apebs, m < # pebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs) ⊦ ⟪mtd_asm_markbad#(m; pebs; err)⟫ ⟨aubi_io_markbad#(m; apebs; err0)⟩ (abs(pebs, apebs) ∧ err = err0)

Proof step 10:
apebs[m] = mkpeb(aehdr, avhdr, buf, m0, false), pebs[m] = mkpeb(buf0, m1, false), m < # apebs, m < # pebs, abs(pebs, apebs), abs-peb(mkpeb(buf0, m1, false), mkpeb(aehdr, avhdr, buf, m0, false)), mtd-cons(pebs), ubi-io-inv(apebs) ⊦ ⟪mtd_asm_markbad#(m; pebs; err)⟫ ⟨aubi_io_markbad#(m; apebs; err0)⟩ (abs(pebs, apebs) ∧ err = err0)
