Proof step 5 from proof inv-format (previous step)

ino = LEB_SIZE, ino0 = ino ⊦ ⟪ino := 0; afs_format#(n, isdir, ino0, md; 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
