//! Artifact DTO -- public API representation of a file produced by a step.

/// An artifact as exposed by the REST API.
///
/// The storage key is deliberately absent: it is internal plumbing, and callers
/// address an artifact by `(run, step, name)` through the download route.
///
/// # Examples
///
/// ```
/// use chrono::Utc;
/// use ironflow_api::entities::ArtifactResponse;
/// use uuid::Uuid;
///
/// let response = ArtifactResponse {
///     id: Uuid::now_v7(),
///     step_id: Uuid::now_v7(),
///     name: "report.html".to_string(),
///     content_type: "text/html".to_string(),
///     size_bytes: 142,
///     sha256: "0".repeat(64),
///     created_at: Utc::now(),
/// };
/// assert_eq!(response.name, "report.html");
/// ```
