Short answer
AML alert closure evidence should help a later reviewer understand what activity was reviewed, which facts and risk signals were considered, which policy or threshold applied, who reviewed the case, why the closure rationale was defensible and where proof gaps remain. The exact evidence set depends on the institution's systems, policies, risk profile and operating controls.
What closure evidence should explain
When an alert is closed, the decision itself is only one part of the picture. What matters later is the ability to reconstruct what was reviewed, why it was closed and whether the evidence trail is complete, temporally anchored and human-owned.
RecordArc frames this as proof-readiness rather than as a new AML operating system. Monitoring, screening and case systems continue to own the workflow. The proof layer helps expose whether the closure can be explained later.
What a complete record includes
A closed alert proof record should include the decision event, relevant source evidence, investigation notes, policy or rule context, reviewer rationale, approval path, timestamps and known proof gaps.
A useful record also distinguishes evidence from judgment. That separation helps reviewers see which facts were available and which human assessment was applied.

Where source profiles fit
Financial crime evidence often sits across alert systems, case tools, customer records, policy repositories and analyst notes. Source profiles define what each system can expose for read-only mapping.
Field mapping then translates those records into a proof structure. That structure does not replace the source system; it makes the decision path easier to inspect.
Synthetic example
Below is a synthetic alert closure example. It is not customer data and it is not a recommendation about whether a real alert should be closed.
Synthetic example
Synthetic alert closure proof flow
A synthetic transaction-monitoring alert is closed after reviewer analysis. The proof preview links the alert data, customer context, investigation note, rule threshold and approval, then flags a missing policy-version link.
- Ready: alert event, evidence lineage and reviewer approval.
- Weak: timestamp from one source system.
- Missing: linked policy-version reference.
