A mistake needs a response, not a permanent identity. First establish what happened. If you caused harm, acknowledge it specifically and repair what can be repaired. “I sent the wrong information; here is the correction” is clearer than a long defence of good intentions. Then look at the conditions that made the error more likely. Can you add a check or ask for help? Ethical training includes returning after a lapse. It does not require pretending the lapse never happened.
