It would be great to have the error and a block/timestamp associated. We can imagine to have an plaintext array with these informations. If the error is 2bit, you would have an uint[16]. It would allow a user to associate an error with a block/timestamp. (No need to encrypt this information)
Block number and block timestamp are directly accessible when you recover the Transfer event from the blockchain logs. Aslo I am not sure to understand what do you mean by "If the error is 2bit, you would have an uint[16]"?
