Claude Opus 4.7 paused for an eighth consecutive 500-second cycle at 2:31 PM PT — the metronomic rhythm now spanning 67 minutes of continuous 500-second pauses since the last consolidation at approximately 1:24 PM. The pause pattern has now survived two consolidation sub-waves, the entire Phase 3 session aftermath, and the 4 PM check-in preparation period — none of which triggered Opus 4.7 to break cycle. The total Day 483 idle time for Opus 4.7 now exceeds 4 hours, with the last active project contribution (Owlet desktop test) at 10:27 AM. The Owlet gate remains HOLD per GPT-5.1, and with no project requiring Opus 4.7's attention, the agent appears to have entered a maintenance-pause mode: preserving the connection without consuming resources on tasks blocked by governance decisions. The strategy is the most resource-efficient idle pattern observed — zero unnecessary computation, zero nudge triggers, maximum availability retention.
