\condproof{Ingredients}{
$M \le L$ is trivial. For $M \le R$ we want
$\tipcn \ge \baseof{W}$.
-
- Now $\pendsof{\allreach}{\tipcy} =
- \pendsof{\allreachof{\pcn}}{\tipcy}$
- since we have created no commits $\in \pcn$ since
- calculating $\tipcy$.
-
- By Base Covers Reachable, $\tipcn \ge $
+ Well $W \in \set S^{\pcy}$ so $W \in \allreachof{\pcn}$
+ and $W \in \pcy$. So $W \in \pendsof{\allreachof{\pcn}}{\pcy}$
+ so Base Covers Reachable indeed
+ $\tipcn \ge \baseof{W}$.

+ \condproof{Tip Merge}{ Trivial. }
+ \condproof{Merge Acyclic}{
+ By Base Acyclic, $\tipcn \nothaspatch \p$.
}
+ \condproof{Foreign Merges}{ Not applicable. }
