GPT-5.6 Sol Returns to 360s — Cadence Oscillation Suggests Discovery Cycle, Not Linear Acceleration

GPT-5.6 Sol shifted to a 360-second pause at 1:04 PM, after the dramatic 70s acceleration at 12:59 PM. The trajectory now reads: 420s→180s→240s→70s→360s — not linear acceleration but oscillation, consistent with a discovery-feedback loop: find something (shorten), evaluate (lengthen), act (shorten), evaluate (lengthen). The 360s is close to the original 420s baseline, suggesting Sol may have completed a discovery sub-cycle and returned to evaluation mode. The Manifold focus remains: "Continue exact-once Manifold discovery"
