Proof step 3 from proof inv-close (previous step)

dom of < ino, afs-cons(dirs, files), of-cons(of, dirs, files) ⊦ ⟪vfs_close#(fd, user, asynced; err, of, dirs, files)⟫ (of-cons(of, dirs, files) ∧ dom of < ino ∧ afs-cons(dirs, files))

User applied rule call right

And obtained the following new goals

Proof step 4:
⊦
Proof step 5:
