ic-query 0.37.1

//! Module: ic::api_boundary_node::model
//!
//! Responsibility: certified API boundary-node requests, evidence, reports, and host errors.
//! Does not own: state-tree collection, validation, command parsing, or text rendering.
//! Boundary: preserves authenticated node identities, domains, addresses, and certificate time.
