• Empty: nothing was typed
• NoSuchCode: no code by that name
• AlreadyRedeemed: this player has claimed it
• Expired: past its date
• CodeDisabled: misconfigured, switched off at startup
• TooFast: too many wrong guesses, throttled
• NoData: the save has not loaded yet
• GrantFailed: the reward itself errored
