Paste or upload a Soup passport. Verification runs entirely in your
browser — the passport never leaves this device. Same math as soup verify.
This page confirms the passport's signature is mathematically valid (Ed25519 over the hash-chain root) and that its contents are unchanged. It does not certify that the signing key is trusted, and it is not a statement of regulator recognition. It is audit-ready evidence, not a compliance guarantee. Verification is performed locally in your browser; nothing is uploaded or stored.
