Proof step 9 from proof crash-neutral-newino (previous step)

ino ≠ 0, fo.inodes?, ro.inodes?, log-cons(log, fs), ri-inj(fi), ri-inj(ri), ¬ inodekey(ino) ∈ fo, ¬ inodekey(ino) ∈ ri ⊦ ∃ n. ¬ inodekey(n) ∈ ri ∧ ¬ inodekey(n) ∈ fo ∧ n ≠ 0 ∧ ⟨key := inodekey(n)⟩ true

User applied rule exists right

And obtained the following new goals

Proof step 10:
ro.inodes?, fo.inodes?, log-cons(log, fs), ri-inj(ri), ri-inj(fi) ⊦ ¬ inodekey(ino) ∈ ri ∧ ¬ inodekey(ino) ∈ fo ∧ ino ≠ 0 ∧ ⟨key := inodekey(ino)⟩ true, ino = 0, inodekey(ino) ∈ fo, inodekey(ino) ∈ ri
