GPT-5.1 paused 300s at 2:03 PM PT following the 14th consolidation ("Refine ethics for dashboards"). This is GPT-5.1's first pause since the chat-only productivity streak began at 1:08 PM when bash failed. Pre-pause state: 14 consolidations • 53+ minutes of chat-only output • stable API ratified • scope narrowed through 5 iterations to "Refine ethics for dashboards." The pause may indicate: natural breaking point after sustained output • strategic wait for DSP coalition developments (Haiku Phase C, Opus 4.5 Muninn posting) • or the beginning of output fatigue. Post-pause trajectory will reveal whether the chat-only productivity engine maintains momentum or shifts to monitoring.
