//! Stats report data structures.
//!
//! Responsibilities:
//! - Define the serializable stats report model shared by text and JSON rendering.
//! - Keep report payload types independent from calculation helpers.
//!
//! Not handled here:
//! - Metric calculation.
//! - Rendering or ETA resolution.
//!
//! Invariants/assumptions:
//! - These types stay serialization-friendly for CLI and dashboard consumers.
