Proof step 85 from proof RG-restr-ok (previous step)

act2(m + 1) ↔ act1(m + 1), Idle(m + 1, cs1) ↔ Idle(m + 1, cs3), Idle(m + 1, cs2) ↔ Idle(m + 1, cs3), act3(m + 1) ↔ act1(m + 1), m < n, CInv(n, act1, cs1), CInv(n, act3, cs3), Rely(m + 1, cs2, cs3), CInv(n, act2, cs2), Rely(m + 1, cs1, cs2) ⊦ n = 0, Rely(m + 1, cs1, cs3)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 86:
⊦ Rely(m, cs1, cs2) ∧ Rely(m, cs2, cs3) ∧ Inv(cs1) → Rely(m, cs1, cs3)
Proof step 87:
¬(Rely(m + 1, cs1, cs2) ∧ Rely(m + 1, cs2, cs3) ∧ Inv(cs1)), act2(m + 1) ↔ act1(m + 1), Idle(m + 1, cs1) ↔ Idle(m + 1, cs3), Idle(m + 1, cs2) ↔ Idle(m + 1, cs3), act3(m + 1) ↔ act1(m + 1), m < n, CInv(n, act1, cs1), CInv(n, act3, cs3), Rely(m + 1, cs2, cs3), CInv(n, act2, cs2), Rely(m + 1, cs1, cs2) ⊦ n = 0, Rely(m + 1, cs1, cs3)
