Proof step 8 from proof crash-neutral-contains (previous step)

fo.inodes?, ro.inodes?, log-cons(log, fs), ri-inj(fi), ri-inj(ri) ⊦ (⌊EIO⌋ ∨ EIO = ESUCCESS) ∧ ⟨err := EIO; if err = ESUCCESS then boolvar := key ∈ ri else boolvar := ?⟩ true

Heuristic simplifier applied rule simplifier

And obtained the following new goals
