//! Module: api::authority_restore
//!
//! Responsibility: expose authority snapshot/restore-fence workflows to generated endpoints.
//! Does not own: authentication, history proof, transition validation, or persistence.
//! Boundary: converts internal workflow failures into the public Canic error contract.
