+## Launch prompt
+
+```
+Add a hook on session clear and exit to ensure that if a session was started, finalize has completed fully and no additional turns that need to be added to the transcript have happened (update the transcript and republish if so - understand that it may have already been published - still update it and push remotely).
+
+```
+
+## Deferred decisions
+
+_Autonomous-mode low-confidence calls the driver made and would have
+liked operator input on. Appended as the session runs; surfaced at
+finalize. Empty if none._
