Check a Record Join the Waitlist

Layer 03 · After it finishes · Touchstone

Is the result actually true?

A sealed record shows what your AI did. It does not show whether the work was any good. “The tests pass” is a claim, and an AI saying so is not evidence.

Touchstone takes the claim and tries to break it. Real checks run, what they print is kept, and a plain rule with no AI in it hands down the verdict: supported, refuted, or not provable yet.

What you get

Built to prove your AI wrong.

A check that sets out to agree finds agreement. This one sets out to break the claim, and one surviving counterexample outweighs any pile of good news. If nothing can reach the claim, it says so instead of guessing.

How Touchstone works, in full →

What it does not prove

Its limits, before you rely on it.

  • Checked at that moment

    not an attestation

    SUPPORTED means “checked against the evidence captured at that moment, auditable from the dossier.” Where a person has to sign, that signature sits outside this tool.

  • As good as the checks

    not all-seeing

    A verdict covers what the plan thought to check. A claim no check can reach comes back UNVERIFIABLE instead of being guessed at, and that is the honest answer.
