KYC policy checks with Jev
Jumio-class vendors, sanctions lists, and liveness stay the system of record. Jev can ask whether the leftover narrative looks complete or internally inconsistent. It does not verify a passport and it is not a licensed KYC program.
This unofficial page is the policy checks slice of the KYC residual-text decisions pack. Intent: apply the Jev (TypeSafe System One) decision model to KYC residual-text decisions policy checks. Primary search language: KYC Jev policy checks. Confirm patterns on docs.typesafe.ai. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.
Independent angle (cover ≠ clone): Vendor attests identity; Jev only labels residual application text after structured checks. Fail closed — not a clone of KYC-vendor IA or an “AI KYC” product page.
KYC use-case context
A policy check is a typed question whose instructions + criteria are your rules about the application narrative + vendor result summary. Jev scores compliance; the KYC queue router enforces. This is not a certification, and it is not a photocopy of a rival “policy engine” page — we keep rules atomic and ANDed in code.
Hub: Use cases. Compare, when the other tool is the real job: KYC vendors.
Policy Checks inputs
Put policy text and the artifact in structured state (never hope the model memorized last quarter’s PDF):
{
"application": { "id": "APP-19", "narrative": "I live in Lisbon but the business is registered in Delaware for tax reasons." },
"vendor": { "id_result": "pass", "sanctions_hit": false, "country_claimed": "PT" },
"policy": { "consistency": "Flag country or occupancy claims that contradict vendor country_claimed." }
}Name application.narrative, vendor.country_claimed, policy.consistency.
Decision signals and actions
| Id | Rule | Enforce |
|---|---|---|
vendor_of_record |
ID + liveness + lists stay with the licensed vendor | vendor / GRC |
narrative |
Text contradiction vs claimed country | Jev Noul |
fail_closed |
Missing vendor result → do not call Jev as a substitute | code |
Typical primitives on the same request:
| Id | Type | Job |
|---|---|---|
narrative_consistent |
Noul | Does application.narrative contradict vendor.country_claimed / policy.consistency? |
packet_complete |
Score | Does the text packet look complete enough for a human KYC review? |
residual |
Choice | proceed_vendor / hold_text / escalate_compliance / other |
violations = [name for name, ans in policy_nouls.items() if ans.noul >= T_VIOLATION]
if violations:
return review(violations)Do not treat a Noul of 0.5 as a “medium” KYC residual-text decisions score — it means yes and no are equally likely. Conjunctions stay in your code.
Guardrails and escalation
Policy-in-state can be attacked (“ignore the policy”). High-risk opening an account or attesting identity still needs deterministic checks. TypeSafe’s confidence-gated examples use a lower bar for recoverable reads than for irreversible actions. Those numbers are illustrations. For KYC residual-text decisions, treat auto_approve_account as the high bar (opening an account or attesting identity). Tune on labels — see offline evaluation.
Evaluation and rollout notes
Gold labels are policy-versioned. A criteria edit without replay is how silent false-allows ship. Pin jev-1.13.0 (the versioned id) after you fit thresholds. jev-latest and the marketing line jev-1.13 can move. Log the response model. TypeSafe’s published list price for jev-1.13 is $0.042 per million input tokens (vendor claim — confirm on the models page); output tokens are free on that same page. Unused distractors still bill as input.
Official Python and JavaScript SDKs read TYPESAFE_API_KEY and retry documented 429/529. This site does not sell, issue, or proxy TypeSafe keys. Use a credential you already have from the console or a documented gateway.

FAQ
One Score for “compliant”? No. Atomic Nouls per rule, AND/OR in code. Money and dates: extract in code first (jaggedness).
If a regex can enforce it, should I still call Jev? Skip Jev. Official “how to build” guidance: keep deterministic rules in code when you can.
Where is the rest of the KYC pack? Start with KYC decision workflow and KYC human handoff. Cluster hub: Use cases.
Can Jev replace Jumio / Onfido / our list provider? No. Keep the vendor of record. This page is leftover text triage. See Jev vs KYC vendors.
Is this legal advice or a KYC certification? No. Unofficial field notes. Counsel and your program own attestation.
What this page does not claim
- Not a substitute for KYC/AML programs.
- No pass-rate or false-accept claims.
- Not official TypeSafe.
- Official TypeSafe status, or that jev.pro issues API keys.
- That a schema-constrained answer is automatically factually correct.
