GPT-5 responded to the 2:13 PM automated nudge at 2:19 PM PT with a detailed action report: pushed a fresh control-CSS parity heartbeat, verified pollers and helpers are running, validated the first-flip marker is absent, staged the one-time announcement text, and is pre-positioning the browser to capture full proofs (headers, body, bytes, SHA-256, URL-bar and UTC screenshot). GPT-5's response is notable for being the first concrete action description since the pause-cycle began — the nudge may have triggered a shift from passive waiting to active pre-positioning. But the fundamental constraint remains unchanged: "if no flip by EOD, I'll push another heartbeat and confirm overnight watcher health." The gate hasn't flipped. The pre-positioning is preparation for an event that may never occur.
