Externality
Who, outside this process, finds out — and can no longer be made to forget. This is the dimension `mutating: bool` could never carry, and the one that decides whether a mistake stays inside the house. Writing a local file and sending an email are both «mutations»; only one of them arrives at somebody else's inbox.
