Who is making a request, and what they are allowed to do. Three kinds: a user may act only
on their own accounts; a system service is a trusted internal caller acting on the
platform's behalf (its writes keep working through a maintenance pause); an operator is a
human running a manual, fully-audited action — the only kind allowed to run adjust and
reverse. Build one with userActor, systemActor, or operatorActor rather than
hand-writing the tagged union.
