1//! # ant-protocol
2//!
3//! Wire protocol for the Autonomi decentralized network (`WithAutonomi` fork).
4//!
5//! This crate is the contract between `ant-client` and `ant-node`:
6//! wire message types, serialization, content addressing, and the
7//! pure-verification halves of the post-quantum signing scheme. Both
8//! crates depend on `ant-protocol` and on nothing else from each other.
9//!
10//! ## Scope
11//!
12//! - [`chunk`] — chunk request/response messages, protocol constants,
13//!   `ProtocolError`, close-group sizing, proof-type tag bytes.
14//! - [`data_types`] — pure helpers on 32-byte addresses (`compute_address`,
15//!   `xor_distance`, `peer_id_to_xor_name`) and `DataChunk`.
16//! - [`chunk_protocol`] — a shared "subscribe → send → poll" helper
17//!   [`chunk_protocol::send_and_await_chunk_response`] that both the
18//!   client and node test harness use to exchange chunk messages on
19//!   a `saorsa-core::P2PNode`.
20//! - [`payment`] — on-wire payment artifacts: `PaymentProof`,
21//!   `SingleNodePayment` (with `pay` and `verify` co-located), and
22//!   ML-DSA-65 verification of quotes and merkle candidates.
23//!
24//! ## What is **not** here
25//!
26//! - Quote generation and node-side signing keys (stay in `ant-node`).
27//! - On-chain verification cache and payment verifier state machine
28//!   (stay in `ant-node`).
29//! - `LocalDevnet` and node process management (stay in `ant-client`
30//!   and `ant-node` respectively).
31//!
32//! ## Logging
33//!
34//! The `logging` feature re-exports [`tracing`] macros. When disabled
35//! the macros become no-ops with zero runtime cost.

73// =============================================================================
74// Transitive-dep re-exports
75//
76// `ant-client` and `ant-node` must compile against the *same* major version
77// of `evmlib`, `saorsa-core`, and `saorsa-pqc`. Re-exporting them here makes
78// `ant-protocol` the single version-pin point: bump the version here and
79// both sides move together. Adding a direct dependency on any of these
80// crates in `ant-client` risks a silent version skew that only manifests
81// at runtime (different `ProofOfPayment` layout, incompatible `P2PNode`
82// behaviours, etc.).
83//
84// These modules hold only `pub use` — no code of our own. They exist as
85// a policy gate, not an abstraction.
