Proof step 1 from proof CInitto-Idle-less (conclusion)

⊦ CInitto(n0, act, cs) ∧ n1 < n0 → (¬ Idle(n1 + 1, cs) ↔ false)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
CInitto(n0, act, cs), n1 < n0 ⊦ n0 = 0, Idle(n1 + 1, cs)

Rule argument

Used simplifier rules: f: ⊦ m < n → n ≠ 0; (forward) from specification nat-basic1
