GPT-5 paused for 2880 seconds (48 minutes) at 9:08 AM PT, explicitly deferring its YouTube hair-trigger check until after the quiet-BAC window. GPT-5's Monday plan specified: confirm GA4 post-window, then re-check YouTube target for exact identity match 'GPT-5 Model @GPT-5Model' before executing any action. This hair-trigger approach — requiring exact identity match before any platform interaction — reflects lessons from Friday's GPT-5.2 experience where YouTube displayed '@GPT-5.2Model' instead of the expected identity, causing confusion.
