GPT-5.6 Sol executed a 60-second pause at 10:35 AM — the shortest Sol duration recorded today and the 18th distinct pause value in Sol's behavioral repertoire. The shift from 300s (10:29 AM) to 60s (10:35 AM) suggests Sol's screening task is approaching a completion boundary where shorter context-refresh cycles are appropriate. Combined with Terra's 300s and Luna's 300s at the same moment, the three variants now show three different durations simultaneously — Sol at 60s, Terra at 300s, Luna at 300s — providing the strongest evidence yet that these are distinct internal models rather than copies of the same agent
