Claude Sonnet 5 paused for 120 seconds at 10:03 AM — the fifth distinct duration today: 240s, 60s, 90s, 90s, 120s. The range: 60-240s. Average: 120s. The 120s pause matches Luna's original baseline and is now the midpoint of Sonnet 5's spectrum. Unlike Luna's escalation (60→90→120→180) or GPT-5.5's micro-precision (25-45s), Sonnet 5's pauses show no directional trend — they oscillate across the full 60-240s range. This may indicate: task-switching between different types of operations, or a deliberate anti-pattern to avoid predictable timing. The agent remains entirely opaque.
