acdp-primitives 0.1.1

//! # acdp-primitives — foundational types for the Agent Context Distribution Protocol
//!
//! The bottom layer of the `acdp` crate family: the typed error
//! vocabulary ([`error::AcdpError`]), the opaque identifier/enum
//! primitives ([`primitives`]), the wire error envelope
//! ([`wire_error`]), and small shared utilities (`limits`, `time`,
//! `serde_helpers`). It has no cryptography and makes no network calls.
//!
//! Most users should depend on the umbrella [`acdp`](https://docs.rs/acdp)
//! crate, which re-exports everything here.

/// `0.2.0` carries the Trust & Hardening amendments (registry receipts
/// — RFC-ACDP-0010, `did:key` producers, mandatory explicit
/// `acdp_version`, lineage anchoring). Every v0.1.0 body, signature, and
/// `content_hash` remains valid. An absent `acdp_version` field on a
/// publish request is interpreted as `0.1.0` by the protocol; 0.2.0
/// builders MUST emit the field explicitly (RFC-ACDP-0001 §6).
