Proof step 55 from proof inv-readdir (previous step)

err = err0, afs-cons(dirs, files), ispath(p0, ROOT_INO, ino0, dirs, files), of-cons(of, dirs, files), px-parent(user, p0, ROOT_INO, dirs, files), ⌊err0⌋ , ino0 ∈ dirs ∨ ino0 ∈ files ⊦ ⟪skip; if err = ESUCCESS then afs_readdir#(inode, dirs, files, asynced; strings, err)⟫ true

Heuristic symbolic execution applied rule skip right

And obtained the following new goals
