In plain English
SAR/STR decision traceability preserves the evidence, internal policy, authority, reviewer judgment, approval, recorded filing or non-filing outcome, chronology, and limitations around a reporting decision. Obligations are jurisdiction-specific. RecordArc may reconstruct retained context, but it does not decide, recommend, draft for submission, approve, file, or transmit a SAR or STR.
A simple example
A later reviewer asks what retained escalation and review evidence supported a reporting decision. The answer must preserve jurisdiction, policy and human authority rather than imply automated filing judgment.
Five claim classes must remain separate
Law, regulatory guidance, an institution's internal policy, its operating practice, and RecordArc product capability are not interchangeable authorities. A traceability record should label each one explicitly.

United States source note: filing and non-filing documentation
FinCEN's October 9, 2025 FAQ states that the BSA and its implementing regulations do not generally require a financial institution to document a decision not to file a SAR. It also explains that an institution may choose documentation under risk-based internal policies and that a concise statement may often suffice, depending on the facts.
That US clarification must not be generalized to another jurisdiction or converted into a RecordArc requirement. A filed SAR has separate supporting-documentation rules, and institution-specific legal analysis remains outside this article.

Worked illustrative use case: a documented non-filing review
An illustrative US institution chooses under its internal policy to record a non-filing decision after an AML alert investigation. Retained context includes the alert and signal, relevant transaction and customer evidence, the internal policy version, investigation activity, reviewer rationale, escalation record, approval, and recorded non-filing outcome.
The policy version is retained, but the evidence package does not contain the delegation record that shows whether the approver held the required internal authority at that time.
Synthetic example
Internal traceability without a universal legal claim
The authority dimension is Weak and the delegation evidence is Missing/unverifiable. That gap concerns the institution's retained internal authority, not a claim that US law universally required this non-filing note.
- Decision event: recorded non-filing outcome under internal policy.
- Decision-time evidence: alert, investigation, policy version, rationale, escalation, and approval.
- Later-acquired context: follow-up quality review kept outside the original decision set.
- Limitation: the reconstruction does not establish legal sufficiency or whether the institution should have filed.
Filing and non-filing decisions require distinct proof questions
For a filed SAR or STR, a reviewer may ask which evidence supported the filing, which authority approved it, which filing record was retained, and whether supporting documentation is traceable. For a non-filing decision, the reviewer may instead ask which internal policy applied, what rationale and escalation were recorded, and whether the institution chose to retain a note.
The Decision Proof Layer can preserve those distinctions. It must not transform traceability into filing automation or present one jurisdiction's rule as universal.

What a later reviewer asks, what RecordArc reconstructs, and what it does not do
A later reviewer asks whether the jurisdiction and authority were identified, whether evidence and internal policy were available at decision time, whether reviewer and approver roles are traceable, and whether later changes have been kept separate.
RecordArc reconstructs the retained evidence, internal-policy version, human authority, chronology, recorded outcome, and disclosed limitations. It does not decide whether to file, recommend a filing outcome, draft a report for submission, transmit a filing, approve a decision, or certify compliance.
