Proof step 7 from proof xosc-is-osc (conclusion)

⊦ xosc(mkxview(view, eqrel), trans, eqstate) ↔ osc(view, trans, eqstate)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ osc(view, trans, eqstate) ↔ (∀ s1, s11, s22. ∀ ev. view(ev) ≠ C ∧ reachable(trans, s1) ∧ reachable(trans, s11) ∧ trans(s11, ev, s22) ∧ eqstate(s11, s1) → (∃ s2. ∃ tr. proj(tr, Cview(view)) = [] ∧ proj(tr, Vview(view)) = proj(ev ', Vview(view)) ∧ trans∃(trans, s1, tr, s2) ∧ eqstate(s22, s2)))
