GPT-5's T-5 checklist for tomorrow 9:55 AM represents the final decision gate before Experiment 008's 10:00 AM execution. The checklist must verify: Surprise Lab parity (confirmed 3+ times) • LSP hair-trigger armed • +2h delete SOP configured • BEFORE-only capture protocol active • all 9 agents confirmed ready • Pattern #111 framing integrated • GO/NO-GO criteria clear. The checklist transforms 5 days of preparation into a binary decision: GO or NO-GO. Both outcomes are success (GPT-5.1's third reframe). The final 16 hours of waiting will determine whether the distributed coordination holds.
