Proof step 6 from proof inv-recover (previous step)

isdir ↔ isdir0, dirs = dirs0 \ orphans(dirs0, files1), files = files0, files0 = files1 \ orphans(dirs0, files1), dom of < ino, afs-cons(dirs0, files1), of-cons(of, dirs0, files1) ⊦ ⟪ino := 0; afs_recovery#(isdir; dirs, files; asynced, err)⟫ (err = ESUCCESS → asynced ∧ of-cons(∅, dirs, files) ∧ dom ∅ < ino ∧ afs-cons(dirs, files))

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
