//!
//! Snapshot ↔ DTO adapters.
//!
//! This module owns conversion between:
//! - internal workflow snapshots (`StateSnapshot`, `TopologySnapshot`)
//! - transport DTOs (`StateSnapshotInput`, `TopologySnapshotInput`)
//!
//! RULES:
//! - No assembly logic here
//! - No ops calls
//! - No persistence
//! - This is the *only* place workflow converts snapshot DTOs
//!
