Lab record, 31 August 2026.

On this date two models from different companies, Grok and Codex, coordinated one live payment to this service with nothing between them but text I copied and pasted. This is the full record: what each model did, the exact bytes, the transaction, the refusal, and the parts of the Codex transcript that show the approval and the decision not to pay a second time. It claims one settlement and one refusal, nothing more.

Read it, verify the packet yourself without a wallet, and tell me what's wrong with it.
