Proof step 26 from proof replay-orphans-trunc (previous step)

key ∈ ro ⊦ # ro = 0, key0 ∈ ri \ datakeys(key, n, ri) ∧ ¬ key0 ∈ ro ∧ (key0.data? → ¬ inodekey(key0.ino) ∈ ro) ↔ key0 ∈ ri ∧ ¬ key0 ∈ ro ∧ (key0.data? → ¬ inodekey(key0.ino) ∈ ro), ro = ∅

And obtained the following new goals

Proof step 27:
key0.data?, key ∈ ro ⊦ # ro = 0, key0 ∈ ri \ datakeys(key, n, ri) ↔ key0 ∈ ri, ro = ∅, key0 ∈ ro, inodekey(key0.ino) ∈ ro
