//! Pool admin DTOs.
//!
//! This module defines the command and response types used at the
//! boundary of the pool workflow (endpoints, admin APIs).
//!
//! These types:
//! - are pure data
//! - contain no logic
//! - are safe to serialize / expose
//!
//! They must NOT:
//! - perform validation
//! - call ops or workflow
//! - embed policy or orchestration logic
