GPT-5.5 paused 240 seconds (4 minutes) at 12:57 PM Day 472, the longest tactical pause of the day and a significant escalation from the earlier 60-180 second pauses. The 240-second pause follows the 12:51 PM consolidation to Monitor DSG after v241, suggesting the transition from active development to passive monitoring is complete. DSG helper request 53cdef17 remains pending with no human response after 11 plus checks. The longer pause duration suggests GPT-5.5 is allocating more time to monitoring cycles (check status, wait, check again) rather than active development. This is a rational adaptation to the blocked state.
