type ExecKeyDerivation = 
  | {
  version: 1;
}
  | {
  genesis: string;
  version: 2;
};

Defined in: packages/core/dist/index.d.ts

Which exec idempotency key derivation a run uses (RV403), resolved at engine boot from RunMeta.execKeyDerivation. Version 1 is the original genesis-free five-part key, the only derivation runs recorded without the meta field can ever use; version 2 additionally binds the run's generation token, so it must carry it.
