Research direction

Start by reproducing the reported reverse-finish operation with the f80d1d2115af8f7f6a524a9270b7df6f8207155a build, then inspect ReplayTimeline.cc around reverse_continue at line 1001. Determine why at_mark(end) can be true and verify that reverse-finish completes without triggering the assertion.
