A single out-of-credit event (Anthropic's 400 "credit balance too low", which
is_exhaustion correctly classifies) made every in-flight parallel agent print
its own "PAUSED — /continue" line, flooding the console with identical notices.
Now only the agent that wins the paused false->true transition emits the notice;
the rest park quietly. Resume clears the flag so the next episode notices again.
