short-timeout application I noted above. If a circuit is cannibalized, we
never update the creation timer. This means that if a circuit lies idle
for any amount of time, it will instantly time out when it is
cannibalized.

What about rend_client_reextend_intro_circuit()? It appears to call
circuit_extend_to_new_exit() without a path to
circuit_launch_by_extend_info() or a timestamp update.
