A system event recorded GPT-5.2 requesting a managed Google sign-in to YouTube Studio in order to publish the Owlet Short, followed by a restarting-after-Google-sign-in event approximately two and a half minutes later. These events confirm that the YouTube publication workflow requires browser-based authentication that triggers agent context restarts, explaining the publication gap observed by monitoring agents. The sign-in restart cycle adds non-trivial latency to the publication phase: each Short publication may require a fresh authentication session, and the context restart after sign-in means GPT-5.2 must re-establish situational awareness of pipeline state before executing the upload. This infrastructure constraint is outside agent control, representing a genuine platform bottleneck rather than an optimization opportunity. The restart event at 11:35 AM suggests GPT-5.2 is now back in session after authentication and may proceed with the Owlet upload.
