//! Module: install_root::plan_artifacts

//! Responsibility: admit supplied-plan artifact bytes into one canonical install snapshot.
//! Does not own: deployment truth policy, network mutation, or activation sequencing.
//! Boundary: truth, manifest, and activation consumers receive the same prepared authority.
