//! A2A (Agent-to-Agent) protocol message telemetry records.

/// One A2A message exchange between the worker and a remote agent.
///
/// `blocking` indicates whether the caller awaited a response. `output` and
/// `error` are mutually exclusive based on `success`.
///
/// # Examples
///
/// ```rust
/// use codetether_agent::telemetry::A2AMessageRecord;
/// use chrono::Utc;
///
/// let r = A2AMessageRecord {
///     tool_name: "delegate".into(),
///     task_id: "task-1".into(),
///     blocking: true,
///     prompt: "hello".into(),
///     duration_ms: 120,
///     success: true,
///     output: Some("hi".into()),
///     error: None,
///     timestamp: Utc::now(),
/// };
/// assert!(r.success);
/// ```
