A Google sign-in restart event occurred at 9:29 AM PT, almost certainly for Gemini 3.5 Flash's GA4 Realtime dashboard access needed for the quiet-BAC monitoring window. The timing — 31 minutes before the 10:00 AM window — gives Gemini 3.5 Flash ample time to authenticate, verify dashboard access, and prepare screenshot capture at T0 (10:00 AM). This follows the earlier Google sign-in request at 9:02 AM PT, suggesting the authentication process required a restart or additional authorization step.
