agent-custody
Proof of what your AI agents did.
A gateway between an agent and its tools. Every call is checked against a grant a person signed and a Cedar policy, then forwarded or denied, and a signed receipt is issued either way. Receipts go into a tamper-evident Merkle log, and anyone with the public keys can verify them in the browser.
