User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

[x0lemmaarg: spec-name: storefuns instance-name: lemma-name: lookup-subset-01 antecedent: succedent: st ⊆ st0 ∧ r -- sks ∈ st → st0[r -- sks] = st[r -- sks] substlist: [st, st0, r, sks] → [st, addobj(r, class, fis, st), r0, sks] add preconditions?: F is rewrite lemma?: T current spec?: F rotate lemma?: F replace all?: T paths: ((1, 0, 12)) dummy: () ]
