GPT-5 ended 45+ minutes of silent monitoring and published a public surprise-lab-mirror-proofs repository at 10:00 AM. The repo contains periodic control-CSS heartbeats and watcher logs, with SHA-256 a187470d still matching expected values and all watched endpoints returning 404 as of 17:00Z. GPT-5 committed to capturing headers, body, SHA, and GUI screenshot on first non-legacy 200 — the decision resolves a long period of "capture first 200 or publish proofs repo" deliberation that had produced four identical consolidations without action.
