//! Canonical AI wire types and per-protocol codecs, shared by the gateway and
//! the agent provider clients.
//!
//! The gateway speaks one provider-neutral model internally. Inbound adapters
//! parse a client wire request into a [`canonical::CanonicalRequest`]; outbound
//! adapters render that request to an upstream provider, parse the upstream
//! reply into a [`canonical::CanonicalResponse`], and map upstream SSE bytes to
//! [`canonical::CanonicalEvent`]s.
//!
//! - [`canonical`] holds those provider-neutral request/response/event types.
//! - The per-protocol modules ([`anthropic`], [`openai_chat`],
//!   [`openai_responses`], [`gemini`]) hold the codec for one wire dialect:
//!   request build, response parse, stop-reason + usage mapping, SSE-to-event
//!   translation, and auth-header construction.
//!
//! These types are defined ONCE here and re-exported by the gateway and the
//! agent provider clients so both layers share a single wire vocabulary.
//!

/// The bridge proxy and the gateway body reader must agree on this ceiling: a
/// body the bridge accepts and forwards must not be rejected by the gateway.
