+\subsection{Base Acyclic}
+
+Consider some $D \isin B$. If $D = B$, $D \in \pqn$.
+If $D \neq B$, $D \isin L$, so by No Replay $D \le L$
+and by Create Acyclic
+$D \not\in \pqy$. $\qed$
+
+\subsection{Coherence and Patch Inclusion}
+
+Consider some $D \in \py$.
+$B \not\in \py$ so $D \neq B$. So $D \isin B \equiv D \isin L$
+and $D \le B \equiv D \le L$.
+
+Thus $L \haspatch \p \implies B \haspatch P$
+and $L \nothaspatch \p \implies B \nothaspatch P$.
