//! Host-portable pure helpers.
//!
//! The single canonical implementation of the algorithms each host SDK
//! needs to call into: JSON-tree diffing, URL pattern matching, and
//! session state-machine decisions.
//!
//! Every helper is pure (no I/O, no clocks, no native handles; JSON or
//! strings in, JSON or strings out) and is exported on all four binding
//! surfaces — native Rust, wasm-bindgen (`js` feature), WASI C FFI
//! (`wasi` feature), and UniFFI (`uniffi` feature). The cross-SDK
//! fixtures in `engine-compatibility-tests/fixtures/portable/` assert
//! byte-equal output across every host.
