Proof step 28 from proof replay-orphans-trunc (previous step)

key0 = datakey(m, m0), key0.data?, key ∈ ro ⊦ # ro = 0, key0 ∈ ri \ datakeys(key, n, ri) ↔ key0 ∈ ri, ro = ∅, inodekey(m) ∈ ro, key0 ∈ ro

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 29:
key ∈ ro ⊦ # ro = 0, datakey(m, m0) ∈ ri \ datakeys(key, n, ri) ↔ datakey(m, m0) ∈ ri, ro = ∅, datakey(m, m0) ∈ ro, inodekey(m) ∈ ro
