//! Compiled-artifact support for `camel compile` (openspec changes
//! `cli-compile` and `multidoc`).
//!
//! The artifact format appends a marked trailer to a copy of the current
//! executable: v1 is `payload || manifest || fixed footer` (68-byte footer),
//! v2 is `CAMELTR1 || content || index || manifest || footer` (76-byte
//! footer) bundling a multi-document virtual store. This module owns the
//! pieces:
//!
//! - [`trailer`] — deterministic EOF trailer codec (v1 and v2 framing).
//! - [`manifest`] — canonical operational manifest embedded next to the
//!   payload.
//! - [`sources`] — explicit multi-document source selection, resolution,
//!   and confinement (multidoc Task 1.2).
//! - [`store`] — re-export of the canonical virtual-document store model
//!   from `camel-dsl`.
//!
//! The artifact embeds authoring text, never `RouteDefinition` or compiled
//! steps: DSL stays responsible for parsing and interpolation, runtime for
//! lowering and lifecycle.
