Customer support
Draft responses. Never send. Never refund.
Support agents need to read tickets and prepare responses. If they can also send responses or issue refunds, a bad draft or a classification error becomes a real customer action.
Read tickets, draft responses for human review, tag tickets
Send responses directly, issue refunds, process billing changes, close accounts
Every draft is ALLOW. Every billing action is DENY. The support lead is the responsible person in every audit entry -- visible to regulators and internal reviewers.
