Proof step 16 from proof switch-ownership (previous step)

!(me, O2, P)(H), rely(me, O1, H1, O2, H2) ⊦ !(me, O1, P)(H)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 17:
⊦ !(id, O, P)(H) ↔ P(H) ∧ (∀ r. r ∈ H → O(r) = id)
Proof step 18:
!(me, O2, P)(H), rely(me, O1, H1, O2, H2) ⊦ P(H) ∧ (∀ r. r ∈ H → O1(r) = me)

Rule argument

spec: <toplevel> name: owned seq: ⊦ !(id, O, P)(H) ↔ P(H) ∧ (∀ r. r ∈ H → O(r) = id) subst: [H, P, O, id] → [H, P, O1, me] flags: <all paths>

Used terms: H, P, O1, me
