Proof step 71 from proof RG-restr-ok (previous step)

act0(m + 1) ↔ act(m + 1), Idle(m + 1, cs) ↔ Idle(m + 1, cs0), m0 < n, Guar(m0, cs, cs0), m0 ≤ m, CInv(n, act0, cs0), Inv(cs), m < n, (¬ act(m0) → Idle(m0, cs)) → ¬ act0(m0) → Idle(m0, cs0), ∀ m0. n < m0 → Idle(m0, cs) ∧ ¬ act(m0) ⊦ n = 0, m0 = m + 1, Inv(cs0), Rely(m + 1, cs, cs0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 72:
⊦ CInv(m, act, cs) ↔ Inv(cs) ∧ (∀ m0. m < m0 → Idle(m0, cs) ∧ ¬ act(m0))
