Proof step 28 from proof wand-flatten (previous step)

((P0 * P1 -* P2))(H), P0(H0), H0 ⊥ H ⊦ ((P1 -* P2))(H0 ∪ H)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 29:
⊦ ((P0 -* P1))(H) ↔ (∀ H1. H1 ⊥ H ∧ P0(H1) → P1(H1 ∪ H))
Proof step 30:
((P0 * P1 -* P2))(H), P0(H0), H0 ⊥ H ⊦ ∀ H1. H1 ⊥ H0 ∪ H ∧ P1(H1) → P2(H1 ∪ H0 ∪ H)

Rule argument

spec: <toplevel> name: wand seq: ⊦ ((P0 -* P1))(H) ↔ (∀ H1. H1 ⊥ H ∧ P0(H1) → P1(H1 ∪ H)) subst: [H, P1, P0] → [H0 ∪ H, P2, P1] flags: <all paths>
