Struct ChallengeResponse 

pub struct ChallengeResponse {
    pub challenge: String,
    pub session_id: String,
    pub expires_at: String,
    pub tee_attestation: Option<Value>,
}

Server responds from POST /auth/challenge.

Canonical shape: { challenge, sessionId, expiresAt }. teeAttestation is a VTA-specific top-level field documented as a vendor extension — Nitro-Enclave deployments populate it; non- TEE deployments omit it.

Fields

challenge: String

base64url-encoded one-time nonce.

session_id: String

Opaque session identifier the producer echoes into the matching authenticate document.

expires_at: String

ISO-8601 timestamp after which the challenge MUST NOT be honored.

tee_attestation: Option<Value>

VTA-specific (optional): TEE attestation evidence bound to the challenge nonce. Present when the VTA is running inside a Nitro Enclave; proves the challenge was generated within the trusted boundary. Absent for non-TEE deployments.
