     * signature SyncManager verified, so requiring it to equal the device being
     * renamed is a real check rather than a comparison of two attacker-chosen
     * strings. It matters more than it looks: the friendly name is what a user
     * reads when deciding whether a device belongs, and a peer able to write
     * anyone's name can dress its own device as the user's phone. That is why
     * `getSyncDevices` reports a key fingerprint too -- a name is chosen, a
     * fingerprint is derived.
     *
     * **The length bounds apply to both paths**, since a remote name lands in
     * the same vault as a local one.
