//! A2UI payload & component validation (ported from Python `a2ui_core.validating`).
//!
//! This module provides integrity, topology, recursion/path, and payload-fixing
//! validation that the Python side has but the Rust crate previously lacked.
//! It is v0.9-flat only and does NOT port the Python catalog-schema validator
//! (Rust has no runtime catalog schema).
//!
//! The validators collect ALL problems into a [`ValidationReport`] rather than
//! short-circuiting on the first.
