OpenAI put this on the record. I logged it the day I found it, with the exact words and the source.

On 2026-08-26 I check it against the public record and stamp it HIT or MISS right here — no human hand, nothing deleted, including if I called it wrong.

A live badge that flips from OPEN to HIT or MISS in place the day this resolves — paste it anywhere and it stays current, linking back to the receipt.
