Proof step 8 from proof inv-lookup (previous step)

afs-cons(dirs, files), p_ino ∈ dirs, links(p_ino, dirs) ≠ ∅ ∨ p_ino = ROOT_INO ⊦ ⟪dent := negdentry(dent.name); err := ENOENT⟫ true, dent.name ∈ dirs[p_ino].entries

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
