Change what the AI said. Watch Raptor catch it.

This is the exact answer the governed run produced. When Raptor sealed it, it recorded the answer’s SHA-256 fingerprint in the hash chain you just saw. Edit a single character below — a dose, a name, the “Yes” into a “No” — and the fingerprint stops matching. That mismatch is the whole point: with Raptor, no one can quietly rewrite what the AI did.

That check ran against this demo’s receipt, live in your browser. Want to prove it’s not a trick? Verify a real, published Raptor receipt yourself — the client-side verifier recomputes the proof and Raptor’s signature entirely in your browser, with no account and without trusting Raptor. Or paste any receipt hash for a quick server-side check.
