//! Module: dto::component_provisioning
//!
//! Responsibility: carry one canonical Fleet Component provisioning plan across boundaries.
//! Does not own: plan derivation, validation, persistence, root effects, or receipts.
//! Boundary: the Coordinator retains the complete plan and sends each root only its exact batch.
