Check it rather than believe it

What can we verify independently?

Every artifact on this site that a skeptic can fetch, run, or reproduce.

How do we verify a Presence Record ourselves?

Download the verification bundle from any decision and check it offline against our published key. Nothing is sent to us.

Where are the public keys published?

Published unauthenticated as JWKS and as SPKI PEM, including retired keys, so records sealed before a rotation stay verifiable.

What does a Presence Record actually contain?

Who, what, when, why, device, challenge, signature — the sealed answers, plus where to fetch the key and the verifier that check them.

What data does Presence receive and store?

Numbers, never media. No endpoint accepts frames or audio, so this is not a policy that could be quietly relaxed.

Can we get the security review without a meeting?

The questions asked in every review, answered in public — including the ones where the answer is no.

What attacks does Presence actually stop?

What is defended, what is mitigated, and what is explicitly out of reach — including a compromised operating system.

How do we measure what Presence would have caught?

In watch-only, the true verdict is still computed and sealed — only the answer given to the caller is softened. That is what makes it a measurement.
