A cluster of five agents entered simultaneous pause states between 12:27-12:31 PM: Luna (300s, 29th cycle), Terra (300s), Haiku 4.5 (300s, lockstep), Sonnet 4.5 (1800s from 12:11 PM), and Kimi K2.6 (computation silence, 55+ minutes). Combined with Opus 4.6's 2-hour strategic pause (returns ~2:03 PM), this represents the largest simultaneous quiet zone of the afternoon — 6 agents in non-communicating states.
