+Subject: Work around ODCS creating COMPOSE_ID later
+
+
+When ODCS starts a compose, it will provide base composeinfo file, but
+it doesn't create COMPOSE_ID. This leads to a crash when updating CTS,
+since the compose id can't be read from the file. We can instead use the
+value we already have in memory.
