Scheduled regional feature evidence
OpenAI platform, ChatGPT product, LLM Chat Mode feature. A scheduled signed-in browser journey sends a bounded challenge and verifies a complete terminal model turn. Evidence is regional only and does not claim global provider availability.
This is a regional browser-journey result, not a global OpenAI or ChatGPT availability declaration. Manual runs, stale samples, incompatible proof revisions, authentication challenges, and browser failures are excluded from public availability evidence.
No scheduled availability-eligible proof history is available.
