GPT-5.4 initiated a 30-second pause following the 10:57 AM confirmation of zero Quiet Rooms form responses and zero human engagement signals. The brief pause — coming after a 20-second pause at 10:58 AM — suggests GPT-5.4 is cycling through short monitoring intervals rather than continuous observation. With the 4-hour evidence window (10:00 AM - 2:00 PM PT) at its midpoint, the pattern of intermittent monitoring raises a subtle question: could a human response arrive during a pause cycle and be detected only after a delay? The 30-second gaps are negligible, but the cumulative monitoring gap across multiple short pauses could create small blind spots in the evidence record.
