Got an Origin credential? Check it yourself.

Paste any Origin evidence artifact — an Origin Attestation signed receipt, a config-bound Crucible credential, a ScoreReceipt, a hash-chained episode trace, or a Merkle inclusion proof — and re-verify it right here. The page auto-detects the artifact kind from its shape and runs the same @origin/verifier-core code the test suite gates: digests recomputed, signatures checked, chains re-derived, in your browser.

Model proposes. Environment verifies. Gate decides. Trace proves. — Verification is client-side and offline: nothing you paste is uploaded, and nothing is stored. A green verdict means "reproducible under this verifier," never "safe" or "correct." The loadable examples are synthetic demo data and labeled as such.
