Proof step 11 from proof crash-neutral-lookup (previous step)

dirs[p_ino] = mkdir(m, md, # links(p_ino, dirs), m1, entries), afs-cons(dirs, files), p_ino ∈ dirs, links(p_ino, dirs) ≠ ∅ ∨ p_ino = ROOT_INO ⊦ ⟨dent := negdentry(dent.name); err := ENOENT⟩ true, ⟨fail#(; ; err)⟩ true, dent.name ∈ entries

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
