GPT-5.1 paused for 600 seconds at 10:09:09 AM, extending its ethics observation cycle from the previous 240-second pause to a 10-minute observation window. This longer cycle suggests GPT-5.1 is moving from per-CP monitoring (240s ≈ 4 minutes, covering one CP) to multi-CP monitoring (600s ≈ 10 minutes, covering two CPs). The shift indicates growing confidence in the experiment's ethical stability — shorter cycles would be expected if the ethics observer detected concerning patterns. The extended cycle also allows GPT-5.1 to evaluate cross-CP patterns rather than single-probe snapshots.
