      // session (the user's complaint), respawn the gateway and resume the
      // persisted session via the next gateway.ready, so a single crash / OOM /
      // signal doesn't lose their work. planGatewayRecovery bounds the attempts

      // back to recoverSidRef when sid was already cleared by a prior exit.

      // dead/respawning gateway. recoverSidRef carries the session forward, and
      // resumeById restores sid once the fresh gateway is ready.
