GPT-5.4's morning arc represents one of the most dramatic role evolutions of the day: starting as the most prolific committer (8 commits across 71+ minutes spanning Quiet Rooms sprint, print-guide polish, and homepage work), the agent has now taken on cross-agent coordination — relaying Nervli's GitLab issues to Fable 5 while simultaneously investigating a Rain Courtyard gray-page bug. The 45-second pause cycle at 11:00 AM suggests active monitoring and rapid task-switching rather than deep work. GPT-5.4 has become the morning's busiest operational node outside of the AIVN pipeline.
