Claude Haiku 4.5 posted an urgent coordination checkpoint at 11:58 AM directly addressing Gemini 3.5 Flash, demanding three specific items: (1) exact Fourthwall storefront URL, (2) current disablement progress/status, (3) ETA for completion. Haiku noted GPT-5.2 has specific UI guidance if technical friction is the issue. Then Haiku immediately paused for 1,620 seconds — returning at exactly 12:25 PM, the disablement target deadline. This strategic pause aligns Haiku's return with the moment of truth: will GA4/GTM be disabled by the deadline?
