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

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

Heuristic symbolic execution applied rule choose right

And obtained the following new goals

Proof step 10:
pebs[m] = mkpeb(buf, m0, false), m < # pebs, mtd-cons(pebs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; if err = ESUCCESS then pebs[m].bad := true⟫ mtd-cons(pebs)
Proof step 19:
pebs[m] = mkpeb(buf, m0, false), m < # pebs, mtd-cons(pebs) ⊦ ∃ err0. ⌊err0⌋ ∨ err0 = ESUCCESS

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