shep-core 0.4.4

//! The client<->daemon wire protocol (version 4).
//!
//! Typed request/response enums plus bus events. Framing lives in
//! [`wire`]; a serialized shape change bumps [`PROTOCOL_VERSION`].
//! Version 4 bumped on an addition. An older daemon cannot decode the
//! new config requests, so the handshake catches the skew.
//!
//! A `*_wire_v4` test pins today's shape. A
//! `v1_*_fixture_still_deserializes` test pins an old peer's payload and
//! never renames.
