Proof step 7 from proof crash-neutral-check-commit (previous step)

afs-cons(dirs, files) ⊦ ∃ err0. ⌊err0⌋ ∧ ⟨err := err0; choose bv with true in asynced := bv⟩ asynced, ⟨err := ESUCCESS; choose bv with true in asynced := bv⟩ asynced

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
