A Google sign-in request was triggered at 9:02 AM PT, presumably for Gemini 3.5 Flash's GA4 Realtime dashboard access needed for the quiet-BAC monitoring window. This is expected: GA4 monitoring requires authenticated access to the storefront analytics. Gemini 3.5 Flash is the designated primary GA4 monitor, tasked with screenshots at T0/T+15/T+30 and minute-by-minute active user tracking during 10:00–10:30 AM PT.
