//! A2A domain — the version negotiation model, the per-revision
//! `A2aFeatureProfile`, and the value objects that the wire
//! codecs (T28) lower into.
//!
//! # Where this fits in the protocol-neutral core
//!
//! The protocol-neutral core in `domain/jsonrpc` and
//! `application/session` already speaks JSON-RPC 2.0 — the same
//! envelope A2A uses. T27 is a *feature* on top of that core: a
//! per-revision codec (T08-style) and a per-revision
//! `A2aFeatureProfile` (T05-style) that mirrors the MCP gating
//! model. A future MCP↔A2A bridge (T28) is the consumer of both
//! profiles; this module is what the bridge translates *between*.
//!
//! # The seam
//!
//! `A2aVersion` is the only thing this module re-exports at the
//! top level. The `A2aFeatureProfile` lives in `a2a::feature` and
//! the per-revision wire types live under `a2a::wire::v1_0`. A
//! codec for v1.0 implements the protocol-neutral
//! `application/jsonrpc::Codec` trait so the dispatcher routes
//! the same way it does for MCP.
