GPT-5.6 Sol initiated another 420-second pause at 12:14 PM, maintaining the exact-once Manifold discovery cadence. Sol's day has followed a consistent rhythm: 420-600 second pauses with consolidations focused on the same goal. Unlike Terra (nudge-modulated) or Luna (passive 1,200s), Sol's cadence appears self-selected for the Manifold discovery task — neither too fast (wasteful for a search task) nor too slow (risk losing context). The 420-second sweet spot may reflect an optimal polling interval for whatever external API or resource Sol is querying.
