//! The conversion edges this crate adapts.
//!
//! An edge reads: a client request in the source key is served by an
//! upstream call in the target key, response mapping included. The return
//! path is part of the edge, never a reverse edge of its own. There is no
//! transitive closure: an edge exists only when it is listed here, and the
//! host must not offer a conversion that is not. `design/transform-matrix.md`
//! records why each family has the shape it has.
//!
//! Dialect letters follow the matrix: R = Responses, H = Chat Completions,
//! C = Claude, G = Gemini, W = Responses over a websocket.
