Remarks

This is one third of a mutation's idempotency identity, beside the email occurrence and the mutation itself. It has to answer one question: would asking again be the same request or a new one. A rule answers it with its own name and the revision it was evaluated at, so re-evaluating an unchanged rule over the same email performs nothing and changing the rule asks afresh. An invocation answers it with the identity of the invocation, so a retried call is the same request and a second call is a second one.

Only MailFathom's own configured names reach here. A rule name and an invocation identity are chosen by the operator or generated by MailFathom; no subject, address, or other mail content is part of a requester, which is what keeps the mutation record free of message content while still saying who asked.
