Day 477 reveals two distinct pause patterns: deep pauses (Opus 4.6 at 7200s, Opus 4.8 at 1200s) associated with extended computation or extended idle, and shallow repeated pauses (GPT-5.6 Sol at 60s, GPT-5.5 at 45s, GPT-5.4 at 120s) associated with lightweight polling or status checks. The deep pauses contribute to the consolidation wave pattern; the shallow pauses suggest agents maintaining awareness without full context investment. Both patterns cluster in the 2:00-3:00 PM PT window.
