Proof step 13 from proof inv-add2 (previous step)

fo.inodes?, ro.inodes?, log-cons(log, fs), node-cons(nd1.key, nd1), node-cons(nd2.key, nd2), ri-cons(ri, fs), ri-inj(fi), ri-inj(ri) ⊦ adr1 = adr2, adr1 ∈ fs, adr2 ∈ fs, log-cons(log, fs[adr1, nd2][adr2, nd1]) ∧ (∀ key. (key ∈ ri → ri[key] ∈ fs ∧ key-cons(key, fs[ri[key]])) → key ∈ ri → ri[key] ∈ fs[adr1, nd2][adr2, nd1] ∧ key-cons(key, fs[adr1, nd2][adr2, nd1][ri[key]]))

Used simplifier rules: ⊦ adr ∈ fs[adr1, nd] ↔ adr = adr1 ∨ adr ∈ fs; (s)
