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

err0 = err1, root.dir?, fids-cons(root, fs, ofh), pre-readdir(path, err, user, root, fs, ofh) ⊦ ⟪if err = ESUCCESS then strings := dom root[path].entries else strings := ?⟫ true

Heuristic conditional right split applied rule if right

And obtained the following new goals

Proof step 6:
err = ESUCCESS, err0 = err1, root.dir?, fids-cons(root, fs, ofh), pre-readdir(path, err, user, root, fs, ofh) ⊦ ⟪strings := dom root[path].entries⟫ true
Proof step 7:
err0 = err1, root.dir?, fids-cons(root, fs, ofh), pre-readdir(path, err, user, root, fs, ofh) ⊦ ⟪strings := ?⟫ true, err = ESUCCESS
