## Tools (as reported by the server, not verified)

- `keyhalve\_verify`: Verify a KeyHalve-sealed document. Accepts a verify URL, the raw text of a KeyHalve QR code, or a document id \(vp\_…, kh\_…, cb\_…\). Returns the cryptographic verdict: whether the seal exists, its live status \(active/revoked/expired\), ciphertext integrity against the issuance commitment, the KeyHalve r
- `keyhalve\_status`: Live status of a KeyHalve-sealed document by id: active, revoked \(with reason/time\), or outside its validity window. Lighter than keyhalve\_verify — status only, no integrity or rail checks. Use for "is this still good right now?"
- `keyhalve\_explain`: Plain-language explanation of what a KeyHalve verification verdict means and why it can be trusted \(blind rail, three-share custody, commitments, revocation\). Optionally focused on one topic.
