//! RedWire — RedDB's binary TCP/TLS wire protocol.
//!
//! ADR 0001 (`docs/adr/0001-redwire-tcp-protocol.md`) is the
//! normative spec. This module owns the *transport-agnostic* parts:
//! frame layout, message-kind discriminator, flags, and the
//! encode/decode codec. Server-side dispatch (auth handshake,
//! session loop, listener accept) stays in `reddb` and depends on
//! these types.
