Proof step 40 from proof inv-close (previous step)

of[fd] = mkfile(m, mode, m0), dom of < ino0, afs-cons(dirs, files), of-cons(of, dirs, files), fd ∈ of, ⌊err0⌋ ⊦ ⟪if err0 = ESUCCESS then {of := of -- fd; vfs_put_inode#(inode, of, asynced; err0, dirs, files)}⟫ (of-cons(of, dirs, files) ∧ dom of < ino0 ∧ afs-cons(dirs, files))

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 41:
of[fd] = mkfile(m, mode, m0), dom of < ino0, afs-cons(dirs, files), of-cons(of, dirs, files), fd ∈ of, ⌊err0⌋ ⊦ ⟪skip⟫ (of-cons(of, dirs, files) ∧ dom of < ino0 ∧ afs-cons(dirs, files))

Rule argument

pos: right 1
