//! Persistence shapes for imported logs — serializable intermediate structures.
//!
//! ## What this module IS
//!
//! - Plain serde structs that hold an imported log in memory between parsing and
//!   admission (lookup maps, id sets).
//!
//! ## What this module is **NOT**
//!
//! - **Not** a database or store, and **not** an engine. It persists nothing to
//!   disk and analyzes nothing; it is a transient in-memory shape.
//!
//! Structure only.
