Screening
OFAC SDN + Consolidated, UN, EU, UK OFSI: Oyelaran (fuzzy, 0.71) (score 0.71) — discounted. Name-only overlap on a common surname. Date of birth, nationality and all secondary identifiers diverge. Discounted under the institution's two-discriminator rule. Global PEP register: No match (score 0.11) — discounted. No PEP, RCA or close-associate match above the 0.85 review threshold.
Disposition
The activity cannot be resolved at this level and is referred to a senior investigator for determination. Referral is mandatory under the institution's escalation policy on the following grounds: deposit pattern consistent with deliberate threshold avoidance. This determination was produced by heelius-investigator-4.2 · policy-pack us-bsa-2026.08 with a calibrated confidence of 68% and is subject to the institution's quality-assurance sampling programme.
Agree with the escalation. Would have cited the Brazil wire's invoice reference explicitly in the findings section — it is in the evidence but not in the prose.
