protocol/lib.rs
1//! Wire protocol between the host daemon and device agents (design D4).
2//!
3//! Every message is one CBOR item in a length-prefixed frame. The crate holds
4//! the message schema ([`message`], [`snapshot`], [`event`]), structured errors
5//! ([`error`]) and the capability set ([`capability`]); it holds no device code.
6//! See `README.md` for the byte-level layout rules the Kotlin agent follows.
