Proof step 24 from proof eq-io-readdir (previous step)

⟨err := err0⟩ (err = err1), dirs1[m] = mkdir(m3, md0, m4, m5, entries), m ∈ dirs1, ⌊err0⌋ ⊦ ∃ strings. ⟨strings0 := strings; fail#(; ; err)⟩ (strings0 = strings1 ∧ err = err1), dom entries = strings1 ∧ ESUCCESS = err1

Heuristic symbolic execution applied rule assign left

And obtained the following new goals
