1//! Wire-protocol family for an upstream AI provider.
2//!
3//! [`WireProtocol`] names the *request/response shape* a provider speaks, not
4//! the vendor. It is the single key that both the gateway's outbound adapters
5//! and the agent-flow provider clients resolve a wire codec from: `minimax`
6//! speaks [`WireProtocol::Anthropic`]; `moonshot` and `qwen` speak
7//! [`WireProtocol::OpenAiChat`]. Decoupling the protocol from the provider name
8//! is what lets a new vendor reuse an existing codec by declaring its protocol.
