structured-proxy 2.0.1

//! Guards the embedded-construction contract.
//!
//! Downstream products embed the proxy by building a [`ProxyConfig`]
//! programmatically (runtime upstream port, listen address, baked-in
//! descriptors) rather than loading a YAML file. This test lives in a separate
//! crate, so it sees the config types exactly as an external consumer does: if
//! any wiring struct gains `#[non_exhaustive]`, this stops compiling and the
//! embedded API regression is caught here.
