Proof step 18 from proof RG-restr-ok (previous step)

m < n, CInv(n, act0, cs0), CRelyto(m, act, cs, act0, cs0), CInv(n, act, cs), CInitto(m, act, cs) ⊦ n = 0, ∀ m0. m0 ≤ m → CInit(m0, act0, cs0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 19:
m0 ≤ m, m < n, CInv(n, act0, cs0), CRelyto(m, act, cs, act0, cs0), CInv(n, act, cs), CInitto(m, act, cs), m0 < n ⊦ n = 0, CInit(m0, act0, cs0)

Rule argument
