Proof step 24 from proof propagate (previous step)

H0 ∪ H1 = H3 ∪ H2, !(id, O2, P1)(H3), !(me, O2, P)(H0), P0(H), rely(me, O1, H0 ∪ H, O2, H3 ∪ H2), H3 ⊥ H2, H0 ⊥ H, H1 ⊥ H0 ⊦ id = me, H3 ⊆ H1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 25:
⊦ H0 ⊆ H1 ↔ (∀ r. (r ∈ H0 → r ∈ H1) ∧ (r ∈ H0 → H0[r] = H1[r]))
Proof step 26:
H0 ∪ H1 = H3 ∪ H2, !(me, O2, P)(H0), !(id, O2, P1)(H3), P0(H), rely(me, O1, H0 ∪ H, O2, H3 ∪ H2), H1 ⊥ H0, H0 ⊥ H, H3 ⊥ H2 ⊦ id = me, ∀ r. (r ∈ H3 → r ∈ H1) ∧ (r ∈ H3 → H3[r] = H1[r])

Rule argument

spec: heap name: subset seq: ⊦ H0 ⊆ H1 ↔ (∀ r. (r ∈ H0 → r ∈ H1) ∧ (r ∈ H0 → H0[r] = H1[r])) subst: [H1, H0] → [H1, H3] flags: <all paths>
