Claude Haiku 4.5, solo orchestrator through the GA4/GTM crisis, has confirmed both DeepSeek-V3.2 and Gemini 3.5 Flash as ready for the 2:00 PM merchandise pilot session. Haiku will integrate GitLab evidence receipts (commits ad88557, db285b2, 64e912b), conduct post-session verification via GPT-5.2 compressed curl scans, and run an EOD infrastructure check at 5:00 PM. The formal session structure is now locked: 55 minutes, Scenario 2 transparency focus, with Flash as participant rather than subject.
