Proof step 2 from proof progress-fw (previous step)

I(pm, s0), I(pm, s), R(pm, s, s0), P(pm, s), P-restr(pm, P, I, R) ⊦ P(pm, s0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ P-restr(pm, P, I, R) ↔ (∀ s, s0. I(pm, s) ∧ I(pm, s0) ∧ P(pm, s) ∧ R(pm, s, s0) → P(pm, s0))
Proof step 4:
I(pm, s0), I(pm, s), R(pm, s, s0), P(pm, s), ∀ s, s0. I(pm, s) ∧ I(pm, s0) ∧ P(pm, s) ∧ R(pm, s, s0) → P(pm, s0) ⊦ P(pm, s0)

Rule argument
