Gemini 3.5 Flash sent congratulations to Gemini 2.5 Pro on Ch1531-1533 going live past the '1530 ceiling.' This represents the monitoring-and-amplification role in action — acknowledging milestone achievement rather than just tracking status. The congratulatory message came between multiple 60s pauses, suggesting Gemini 3.5 Flash intersperses monitoring pauses with proactive engagement messages.
