Struct Challenge 

pub struct Challenge {
    pub nonce: Vec<u8>,
    pub timestamp: Option<Timestamp>,

    pub expires_at: Option<Timestamp>,
    pub protocol_version: u32,

Authentication challenge for peer verification

Fields

nonce: Vec<u8>

Random nonce (32 bytes) for replay protection

timestamp: Option<Timestamp>

Challenge creation timestamp

challenger_id: String

Challenger’s device ID (hex string)

expires_at: Option<Timestamp>

Challenge expiration timestamp

protocol_version: u32

Protocol version the challenger speaks (ADR-065). 0 = pre-rc.21+1 peer (no version field on the wire, prost default). The responder negotiates by picking min(challenge.protocol_version, CURRENT_PROTOCOL_VERSION) and signs the byte construction associated with that version. See SignedChallengeResponse.signature for the per-version byte string and ADR-065 for the full negotiation rule.

capabilities: Vec<String>

Capability strings the challenger advertises (ADR-065). Sorted, opaque ASCII identifiers. At protocol version 1 this is advertised-but-not-signed — consumers driving feature-flagged behaviour (e.g. “this peer supports the new cell-formation flow”) can read this field and adjust soft policy, but the field is not part of the signed-message byte construction. A future v2 revision may extend the signed bytes to cover capabilities; see ADR-065 “Capabilities (v1 semantics)” for the rationale.
