  10. Ethics in Architecture advanced

    A product's growth team wants account deletion to take 30 days of "cooling off", during which the account is recoverable and the user receives win-back emails. The architecture already implements this as a soft-delete flag. What happens when the first erasure request arrives citing a legal right, and what should have been designed differently?
