Proof step 12 from proof inv-markbad (previous step)

pebs[m] = mkpeb(buf, m0, false), err0 = ESUCCESS, m < # pebs, mtd-cons(pebs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪pebs[m].bad := true⟫ mtd-cons(pebs)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 13:
pebs[m] = mkpeb(buf, m0, false), err0 = ESUCCESS, m < # pebs, mtd-cons(pebs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ mtd-cons(pebs[m, pebs[m].bad:= true])
