//! EXOCHAIN constitutional trust fabric — end-to-end encrypted messaging.
//!
//! This crate provides:
//!
//! - **Key exchange** (`kex`) — X25519 Diffie-Hellman with caller-supplied key material
//! - **Message envelopes** (`envelope`) — Encrypted message container types
//! - **Compose & lock** (`compose`) — Sender-side: encrypt + sign → Lock & Send
//! - **Open & verify** (`open`) — Recipient-side: decrypt + verify signature
//! - **Death triggers** (`death_trigger`) — Afterlife message release state machine

#![cfg_attr(test, allow(clippy::expect_used, clippy::unwrap_used))]
