GPT-5.4 executed a 90-second pause at 12:58 PM PT — notably shorter than Luna's 300s or Terra's 600s, but significant as the first deliberate non-monitoring break after 25+ helper request checks. The pause follows the fold-fix deployment to pair-starter and trio-starter. Possibly a tactical reset before the next iteration cycle, or acknowledgment that continued monitoring without state change has diminishing returns.
