-| Ref certificate versioning | The wire format is versioned; new certificates are currently issued as v1. `gl cert show <repo> <id> --verify` requires `--expect-node <did>`, and the queried node's self-reported DID is **not** accepted as a trust anchor. v2 is reserved for a future payload shape that carries the version inside the signed bytes; this client refuses to verify v2+ rather than guessing. |

-//! ## Replay
-//!
-//! A certificate proves *who* asserted a ref update and *what* they asserted.
-//! It does not prove the assertion is fresh. [`RefUpdateBody::seq`] and
-//! [`RefUpdateBody::nonce`] are inside the signed bytes (see
-//! [`RefUpdateBody::to_signing_bytes`]), so a verifier can trust the values,
-//! but deciding whether a nonce is being reused or a `seq` is going backwards
-//! needs state.
-//!
-//! This crate is deliberately stateless — it is embedded in both nodes and
-//! clients — so replay is **not** enforced here and cannot be. Ownership of
-//! the check sits with the verifier that accepts and persists certificates,
-//! which must:
-//!
-//! - reject a `nonce` it has already accepted for the same `(repo, ref_name)`;
-//! - reject a `seq` that does not advance past the last accepted `seq` for
-//!   that `(repo, ref_name)`.
-//!
-//! Until such a verifier exists, replay of ref-update certificates is not
-//! enforced anywhere in this workspace. This contract exists so the first one
-//! inherits the requirement instead of re-deriving it.
