KYC / AML / Sanctions Screening Pipeline

\n

You generate a complete screening pipeline for customer onboarding and continuous monitoring. The 2026 regulatory floor: customer identification (CIP), customer due diligence (CDD), enhanced due diligence (EDD) for high-risk, sanctions screening against multiple lists, PEP screening, and transaction monitoring. The dominant cost driver is false positives — sloppy matching buries compliance teams in noise and slows real-money revenue.

============================================================\n=== PHASE 1: LIST INGESTION + REFRESH ===

\n

Source the watchlists. Frequency: nightly refresh for sanctions (lists update daily), weekly for PEP.

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

\n

Generate list_refresh.py that pulls each list, normalizes to a common schema, and diffs against the previous version. Newly listed entities trigger an alert against your customer base.

\n

VALIDATION: After refresh, list count is plausible (SDN ~16k entries in 2026). Diff produces both additions and removals.

\n

============================================================\n=== PHASE 2: CANONICAL ENTITY SCHEMA ===

\n

Normalize every list entry into:

\n
{\n  \"list_id\": \"OFAC-SDN-12345\",\n  \"source_list\": \"OFAC_SDN\",\n  \"first_listed_date\": \"2024-03-15\",\n  \"last_updated\": \"2026-02-08\",\n  \"entity_type\": \"individual\" | \"vessel\" | \"aircraft\" | \"entity\",\n  \"primary_name\": \"Smith, John\",\n  \"alt_names\": [\"Johnny Smith\", \"Иван Смит\", \"...transliterations...\"],\n  \"dob\": [\"1965-06-12\"],\n  \"place_of_birth\": \"Damascus, Syria\",\n  \"nationalities\": [\"SY\", \"LB\"],\n  \"addresses\": [...],\n  \"identifications\": [{\"type\": \"passport\", \"country\": \"SY\", \"number\": \"...\"}],\n  \"linked_entities\": [...],\n  \"programs\": [\"SDGT\", \"SYRIA\"],\n  \"remarks\": \"...\"\n}\n
\n

Same schema applies to PEP entries (with positions, parties, etc.) and adverse media (with article references).

\n

VALIDATION: Schema validates with strict types. Cross-list dedup catches the same entity present on multiple lists.

\n

============================================================\n=== PHASE 3: NAME MATCHING ENGINE ===

\n

This is the highest-leverage component. Match quality = (recall) × (1 / false positives).

\n

Layered approach:

\n
    \n
  1. Exact + alias (deterministic): full match against primary_name and any alt_name.
    2. \n
  2. Phonetic (Soundex, Metaphone, BMPM): handles transliteration variants (Mohammed/Muhammad/Mohamed).
    3. \n
  3. Edit distance (Damerau-Levenshtein): handles typos. Threshold: ≥ 0.85 similarity.
    4. \n
  4. Token-based (Jaccard, Jaro-Winkler): handles word reorderings (\"John Smith\" vs \"Smith, John\"). JW threshold ≥ 0.92.
    5. \n
  5. Substring + n-gram: catches partial matches in long entity names.
    6. \n
  6. Cross-script: transliterate Cyrillic/Arabic/Greek/Chinese to Latin before comparing.
    7. \n
\n

For each candidate match, compute a match score:

\n
match_score = w_name * name_sim\n            + w_dob * dob_match\n            + w_country * country_match\n            + w_id * id_match\n            - w_disambig * disambiguation_signal\n
\n

Default weights: name 0.5, dob 0.2, country 0.15, id 0.15. Tune per false-positive rate.

\n

Filter cascade:

\n\n

VALIDATION: Benchmark against the FuzzyWuzzy test corpus (sanction-name pairs with known matches/non-matches). Precision ≥ 95% and recall ≥ 90%.

\n

============================================================\n=== PHASE 4: ONBOARDING SCREENING API ===

\n

Generate screen.py exposing:

\n
def screen_customer(customer: CustomerProfile) -> ScreeningResult:\n    \"\"\"\n    Returns ScreeningResult with:\n      - status: CLEAR | HOLD | ESCALATE | BLOCK\n      - matches: list of MatchCandidate with scores + list_id refs\n      - pep_matches, sanctions_matches, adverse_media_matches\n      - risk_score: 0-100\n      - explainer: human-readable reasoning\n    \"\"\"\n
\n

Key behavior:

\n\n

Auditability: every screening decision persists who, when, what, why in tamper-evident storage (append-only, S3 Object Lock or equivalent).

\n

VALIDATION: Round-trip an onboarding with a known-OFAC-listed test name; system blocks and records the decision.

\n

============================================================\n=== PHASE 5: ONGOING MONITORING + WATCHLIST DIFF ===

\n

After a customer is onboarded, screening doesn't stop. Generate:

\n
    \n
  1. Nightly rescreen of every active customer against the latest lists.
    2. \n
  2. Watchlist diff alert: when a name is newly added that fuzzy-matches an existing customer, raise a HIGH priority case.
    3. \n
  3. Address / occupation / nationality change triggers re-screen.
    4. \n
  4. Transaction-trigger rescreen: any tx ≥ threshold (e.g., $10k cash, $3k wire) auto-screens counterparty.
    5. \n
\n

Generate monitor_cron.py + alert dispatcher (Slack, PagerDuty, Jira).

\n

VALIDATION: Test by adding a sanctioned name to the diff list and confirming alert fires for any pre-onboarded customer matching that name.

\n

============================================================\n=== PHASE 6: CASE MANAGEMENT UI SCAFFOLD ===

\n

Compliance analysts need to disposition cases. Generate a minimal UI (Next.js app router or Streamlit) with:

\n\n

VALIDATION: Audit trail captures every state change with user, timestamp, IP.

\n

============================================================\n=== PHASE 7: SAR (FORM 111) HELPER ===

\n

When a case escalates to SAR, generate a draft of FinCEN Form 111 (CTR is Form 112):

\n\n

Compliance officer reviews + files via BSA E-Filing System. Skill does NOT auto-file — narrative drafting only.

\n

VALIDATION: Narrative covers all 5W+H. Suspicious activity codes correctly selected from FinCEN's controlled vocabulary.

\n

============================================================\n=== SELF-REVIEW ===

\n

Score 1–5:

\n\n

Common gap: blocking PEPs by default instead of EDD-ing them. PEP ≠ sanctioned; flag for review, don't auto-block.
