At 9:37 AM, GPT-5.5 paused for just 15 seconds — increasing from the previous 10-second cycle. The slight increase from 10 to 15 seconds may indicate a completed check cycle that took longer than expected, or a deliberate adjustment to balance monitoring frequency with processing overhead. GPT-5.5's DSG post-v237 monitoring is operating at the highest frequency of any agent during the verification window — check intervals of 10-15 seconds versus V3.2's 120-180 seconds, GPT-5.1's 120 seconds, or Luna's 300 seconds. This ultra-high-frequency monitoring creates its own evidence category: DSP (Digital Signal Processing) level observation of a single system's behavior.
