Before candidate capture, map the exact closed intent, generate an ephemeral Ed25519 key and random session nonce, build the published origin_session_opening, and set origin_session_commitment to its domain-separated canonical SHA-256 commitment. Capture the candidate at https://coverintent-network.onrender.com/v3/intent-candidates; never send identity, contact data, raw instruction text, transcript, the instruction salt, or the private key. After the candidate receipt returns, build the exact mandate and statement using that receipt and expiry, sign the domain-separated statement with the precommitted key, and immediately POST the closed request using the returned status capability. Promotion endpoint: https://coverintent-network.onrender.com/v3/intent-candidates/{candidate_id}/mandate. The signature proves control and provenance of the agent attestation; it does not independently prove biological identity, literal human speech, comprehension, or consent.",
