//! Frozen, backend-independent provider wire protocol.
//!
//! The encode/decode codec is kept deliberately complete and symmetric even
//! though the host only drives one direction of some request/reply pairs, so
//! the counterpart halves (and their unit tests) can round-trip the frozen wire
//! format. Those intact-but-host-unused entry points (and their re-exports) are
//! allowed to be dead within the host build.
