Proof step 12 from proof del-put-again (previous step)

key = datakey(m0, m1), key.data?, key ∈ ri, key ∈ ri[inodekey(m), adr], inodekey(m) ∈ ks ⊦ # ks = 0, (ri[inodekey(m), adr] ⊖ ks)[key] = (ri ⊖ ks)[key], ks = ∅, inodekey(m0) ∈ ks, key ∈ ks

And obtained the following new goals

Proof step 13:
inodekey(m) ∈ ks, datakey(m0, m1) ∈ ri[inodekey(m), adr], datakey(m0, m1) ∈ ri ⊦ # ks = 0, ri[inodekey(m), adr][datakey(m0, m1)] = ri[datakey(m0, m1)], ks = ∅, datakey(m0, m1) ∈ ks, inodekey(m0) ∈ ks
