1//! A2A domain — the version negotiation model, the per-revision
2//! `A2aFeatureProfile`, and the value objects that the wire
3//! codecs (T28) lower into.
4//!
5//! # Where this fits in the protocol-neutral core
6//!
7//! The protocol-neutral core in `domain/jsonrpc` and
8//! `application/session` already speaks JSON-RPC 2.0 — the same
9//! envelope A2A uses. T27 is a *feature* on top of that core: a
10//! per-revision codec (T08-style) and a per-revision
11//! `A2aFeatureProfile` (T05-style) that mirrors the MCP gating
12//! model. A future MCP↔A2A bridge (T28) is the consumer of both
13//! profiles; this module is what the bridge translates *between*.
14//!
15//! # The seam
16//!
17//! `A2aVersion` is the only thing this module re-exports at the
18//! top level. The `A2aFeatureProfile` lives in `a2a::feature` and
19//! the per-revision wire types live under `a2a::wire::v1_0`. A
20//! codec for v1.0 implements the protocol-neutral
21//! `application/jsonrpc::Codec` trait so the dispatcher routes
22//! the same way it does for MCP.
