Lets an agent manage local identities and public contact cards, and hide a message inside ordinary-looking cover text via concealment carriers, while inspecting and verifying sealed notes and encrypted capsules entirely on the user's own machine. Passphrases and plaintext stay in the companion CLI, and neither server has any outbound network capability.
