-\section{Traversal phase --- proofs}
-
-For each operation called for by the traversal algorithms, we prove
-that the commit generation preconditions are met.
-
-\subsection{Tip Base Merge}
-
-$L = W$, $R = \tipcn$.
-
-TODO TBD
-
-Afterwards, $\baseof{W} = \tipcn$.
-
-\subsection{Tip Source Merge}
-
-In fact, we do this backwards: $L = S$, $R = W$.  Since $S \in \pcy$,
-the resulting $C \in \pcy$ and the remaining properties of the Merge
-commit construction are symmetrical in $L$ and $R$ so this is fine.
-
-By the results of Tip Base Merge, $\baseof{W} = \tipcn$.
-
-By Base Ends Supreme, $\tipcn \ge \baseof{S}$ i.e.
-$\baseof{R} \ge \baseof{L}$.
-
-Either $\baseof{L} = \baseof{M}$, or we must choose a different $M$ in
-which case $M = \baseof{S}$ will suffice.
