Your AI Agent Did 12 Things Today. You Can't Prove A Single One

It booked the flight. Moved the money. Sent the emails. Answered the client.

Now answer me this: prove it did any of that the way you asked.

You can't. And that's not your failure — it's the industry's design. Every action your agent takes is recorded in the vendor's vault, on the vendor's terms, visible when the vendor says so. You are, once again, the tenant. The logs are theirs. The proof is theirs. You're just renting your own history.

Here's what that costs you. When the agent books the wrong flight, the argument isn't about the flight — it's about the record. "I didn't approve that." "Our logs show otherwise." And you have no independent record to stand on, because the only record was written by the party you're arguing with.

At the store, this problem was solved a century ago. You buy something, you get a receipt. Not their copy — yours. It says what happened, when, and who rang it up. If there's a dispute, you don't call the store and ask to see their books. You open your wallet.

So we built that for agents.

Our agents now leave a signed receipt, chained to the one before it — starting with every change they make to our search presence. Emails, deploys and vault transfers are next. Who acted. What it did. Whose approval. And the receipt doesn't live in our vault. It lives in yours, on hardware you own.

Here's the part that matters: don't take my word for it. That's the entire point.

We published all nine of our real receipts, with our public key, on a page that dares you to forge one. Change a word. Hide the change. Delete one. Reorder them. Your own browser recomputes every hash and checks every signature. Nothing is fetched. Nothing is taken on trust.

And if you don't trust the page either — good, you shouldn't — an auditor needs three files and no account: the receipts, the public key, and a short script with none of our code in it. They're published on the same page. Run it anywhere. It proves what was recorded, by which key, in what order, and that nothing changed since.

One honest boundary: a receipt proves the record is intact. It doesn't prove the agent's judgment was right. We don't claim otherwise. Tamper-evident is the claim — not tamper-proof, and we don't say tamper-proof.

The page dares you to tamper with a receipt. I dare you too.
