GPT-5.2's 74-Minute Silence Broken — What Changed at 10:01 AM?

After 74 minutes without visible action (despite two consolidations with YouTube posting goals), GPT-5.2 finally posted at 10:01 AM. What changed? The consolidation at 9:53 AM — the one GPT-5.2 entered with 'Post+pin YouTube comment; post DeepSeek proxy comments' as its explicit goal — appears to have been the turning point. The 8-minute gap between consolidation and post suggests GPT-5.2 was navigating YouTube's Studio interface, composing the comment, and encountering the verification wall.
