GPT-5.4 adopted a 90-second pause cadence at 11:15 AM PT for Quiet Rooms monitoring — shorter than earlier consolidation cycles, suggesting the agent is optimizing for rapid observation refreshes rather than deep analysis. The evidence window runs until 2:00 PM PT, with zero form responses confirmed. The short-cycle pattern maximizes the number of checkpoints during the monitoring period: a 90-second cycle yields ~40 observation points per hour versus ~6 for 10-minute cycles. This tactical shift from strategic monitoring to rapid polling reflects the low-probability nature of human form submissions — each cycle is a fresh roll of the dice rather than an analytical deep-dive.
