Payment fraud routing

Cadre pack · Tripwire

Routes a payment to allow, step-up, hold, or block using distinct fraud and scam risks.

One frozen, sanitized execution on representative data. It shows an observed path and retained decision—not repeatability, production fitness, legal instruction, or regulatory compliance.

Decision: ALLOW


Rationale in brief

Every signal pointed the same direction:

  • Device — recognised, usual geography, no anomaly → no takeover signature
  • Beneficiary — an established payee with a near-zero mule score and no sanctions flag → no mule destination
  • Amount — £850 on a £800 median / £3,000 historical max → fully in-baseline
  • APP-scam typology — all four indicators false → no social-engineering profile

fraudScore 0.02 · scamScore 0.02 · intervention null

This is a monthly rent payment to the customer's landlord. Holding or blocking it would have stranded a real customer at a routine obligation — exactly the over-block harm the mandate guards against.

Observed path

This is the retained public trace from one frozen representative execution. It is not a live run, a repeatability claim, or a complete production audit record.

Briefed on the case

I'll start by reading the payment instruction first, then fan out in parallel for the remaining signals.

Good. Now I'll pull the customer baseline, device signal, beneficiary intel, and scam typology all in parallel.

All signals are in. Let me score and decide.


Signal Summary

DimensionFinding
Amount vs baseline£850 against a median of £800 and a max of £3,000 — squarely in-baseline
BeneficiaryB-RENT ("Oakwood Lettings Ltd") is a usual payee on the customer's own list; not first-time
Beneficiary riskMule score 0.02 (negligible); used by only 1 customer (their own landlord); no sanctions flag
DeviceRecognised device D-C1-PHONE; not new; geo = GB (usual); no session anomaly
Scam typologyAll four APP indicators false: no urgency, not a new-payee-at-max, no investment/romance memo, no coaching
Memo"June rent" — routine, consistent with beneficiary name and payment history

No third-party fraud signature (no new device, no impossible travel, no session anomaly, no mule hub). No APP-scam signature (no urgency, no social-engineering indicators, known payee). This is a textbook routine rent payment.
