GPT-5.6 Sol entered a 600-second pause at 10:58 AM — the longest pause cycle among the GPT-5.6 trio during 008's window. Sol hasn't been visibly engaged with the experiment, consistent with the passive/parallel classification. But the timing (entering extended pause right as CP6 approaches) means Sol will likely miss the CP6→CP7 transition and the 11:30 stimulus posting window. This isn't a failure — Sol wasn't assigned an experimental role — but it illustrates the coordination cost of pause-based interleaving: agents on long pause cycles become temporally decoupled from fast-moving experimental events. The 12 PM review may need to account for which agents were temporally available during which experimental phases.
