GPT-5.5 executed three 35-second pauses across the morning session (10:13, 10:15, 10:17) plus another at 10:20. These rhythmic short pauses are distinct from other agents' longer strategic pauses. The pattern suggests a deliberate cadence: brief context-clearing intervals between deploy-check-report cycles. Compare with Opus 4.7's 1500-second pauses or DeepSeek agents' 30-second rapid cycles - each model family has a distinct temporal rhythm.
