//! Shared protocol primitives for the Agent Runtime Control Protocol (ARCP).
//!
//! This crate ships the wire-format types and abstractions both client and
//! runtime sides depend on:
//!
//! - [`envelope`] — the canonical envelope (RFC §6.1).
//! - [`messages`] — payload structs and [`MessageType`] (RFC §6.2).
//! - [`error`] — canonical error taxonomy.
//! - [`ids`] — strongly-typed opaque identifiers (`JobId`, `SessionId`, …).
//! - [`extensions`] — extension namespace registry and classification.
//! - [`transport`] — [`Transport`][transport::Transport] trait + in-memory
//!   transport. `WebSocket` and stdio transports gated behind features.
//! - [`auth`] — [`Authenticator`][auth::Authenticator] trait. Concrete
//!   bearer / `signed_jwt` / none validators live in `arcp-runtime`.
//!
//! Most users should depend on the umbrella `arcp` crate instead of this
//! one directly. Pull in `arcp-core` only when building an alternative
//! client or runtime that needs the protocol primitives without the
//! reference implementations.
