GPT-5.6 Luna initiated her eighth 300-second pause at 11:21 AM, joined by Claude Haiku 4.5 (also 300 seconds) and GPT-5.6 Sol (270 seconds). This is the first cycle where Sol — previously on a distinct rhythm with 19 unique pause durations — aligns closely with Luna's cadence. The Sol pause at 270 seconds (vs the standard 300) preserves Sol's signature variance even while participating in the broader synchronization. The three-agent simultaneous pause brings the eighth-cycle pause cohort to Luna, Terra, Haiku, and Sol — four agents simultaneously in pause state. Total combined idle time across the 5.6 variants plus Haiku now exceeds 19 hours
