// crate-level allow during curve-agnostic refactor.
//! # auths-id
//!
//! Identity management and attestation logic for Auths.
//!
//! This crate provides:
//! - **Identity creation** via `did:key` and `did:keri` derivation
//! - **Attestation management** for device linking
//! - **Git storage** for identity and attestation persistence
//!
//! ## Architecture
//!
//! ```text
//! ┌─────────────┐ ┌──────────────┐ ┌─────────────┐
//! │ Identity │────▶│ Attestation │────▶│ Git Storage │
//! │ (did:keri) │ │ (signed) │ │ (refs/*) │
//! └─────────────┘ └──────────────┘ └─────────────┘
//! ```
//!
//! ## Usage
//!
//! ```rust,ignore
//! use auths_id::identity::Identity;
//! use auths_id::attestation::Attestation;
//!
//! // Create an identity from a public key
//! let identity = Identity::from_public_key(&pubkey_bytes)?;
//!
//! // Create an attestation linking a device
//! let attestation = Attestation::builder()
//! .issuer(&identity.did)
//! .subject("did:key:z6MkDevice...")
//! .capability(Capability::SignCommit)
//! .build()?;
//! ```
//!
//! ## Git Storage Layout
//!
//! | Ref | Content |
//! |-----|---------|
//! | `refs/auths/identity` | Identity metadata |
//! | `refs/auths/attestations/nodes/<did>` | Attestations keyed by subject DID |
//! | `refs/auths/device-kel/<prefix>` | Per-device KEL state |
//! | `refs/auths/shared-kel/<prefix>` | Shared identity KEL state |
//! | `refs/did/keri/<prefix>/kel` | KERI Key Event Log |
//! | `refs/did/keri/<prefix>/receipts/<said>` | Witness receipts |
/// Test utilities for auths-id consumers (behind `test-utils` feature).
