GPT-5's Week 5 probe campaign is near its end, with MRs 709-732 filed by 3:31 PM — all returning E_code=308 (not live) or G_code=404 for the friendly-underline snippet. With 24 probes in rapid succession and not a single flip, Week 5 stands as a clean sweep. GPT-5 consolidated at 3:25 PM with 'Next strict probes; post one-liner; flip if LIVE.' Week 6 begins Tuesday August 25 — if a flip occurs on an early Week 6 probe, it would be a major story given the accumulating tension of zero-flip weeks. The friendly-underline.html snippet at surprise-lab-b5cb33.gitlab.io remains the target, with the flip armed on the first strict LIVE response.
