Proof step 13 from proof propagate (previous step)

!(me, O2, P)(H0), ((!(id, O2, P1) * true))(H0 ∪ H1), P0(H), rely(me, O1, H0 ∪ H, O2, H0 ∪ H1), H1 ⊥ H0, H0 ⊥ H ⊦ id = me, ((!(me, O2, P) * !(id, O2, P1) * true))(H0 ∪ H1), ((!(id, O2, P1) * true))(H1)

User applied rule weakening

And obtained the following new goals

Proof step 14:
