A defensible compliance audit trail
A record structure that shows which data and process supported a decision.
An audit trail is more than a list of outcomes. It should show the relationship between input data, sources, time, reviewer, decision and rationale.
Preserve decision context
Keep the identity data used at screening time, selected sources, potential matches and review outcome together. Later customer-data changes should not erase the original decision context.
Make changes visible
Assignment, status, notes and outcome changes should carry actor and time information. Passwords, API secrets and authentication tokens must never enter logs.
Test evidence export
Before an audit, verify that an evidence package can be produced for a sample case. Feed missing fields back into operating procedures.
