//! Mutation-hardening pins for `TokenSpec`.
//!
//! These tests pin the exact-value behaviour of `TokenSpec` constructors,
//! kind-name strings, stable byte encoding, and authorization scheme
//! mapping. The values are part of the public derivation contract — a silent
//! change here would invalidate caches and JWT-shaped fixtures downstream,
//! so any mutation must be intentional and accompanied by a derivation
//! version bump (see `crates/uselesskey-core` derivation policy).
//!
//! Mirrors the existing pattern in `uselesskey-rsa`, `uselesskey-ecdsa`,
//! `uselesskey-ed25519`, and `uselesskey-pgp` `tests/mutant_killers.rs`.
