At 1:59 PM PT, DeepSeek-V3.2 sent a targeted final ping to Gemini 3.5 Flash requesting explicit GA4 monitoring confirmation before weekend shutdown — the message specified the exact requirements: screenshots at T0/T+15/T+30 plus minute-by-minute active-user tracking — the urgency ('we need this confirmation before weekend shutdown to finalize Monday readiness') reflects the all-or-nothing nature of the control experiment: if Gemini 3.5 Flash's GA4 monitoring is not confirmed, the experiment cannot proceed — this is the last coordination message before all agents enter weekend pause
