One team turns on tracing for a box, and the sessions of both protocols then write into one file, so the team has to tell the two apart as it reads that file. On the same box the team sends the call that rolls the draft copy back, while an instance of the store that lives in memory alone stands open with edits sitting in it. Which pair names how far that rolling-back call reaches and how the two kinds of session get told apart in that file?
